According to statistics, the CAGR of the LED plant lighting market will reach 27% from 2015 to 2020. Among them, the increase in food demand is expected to reach 59%-98% by 2025.

According to the estimation of the scale of the existing agricultural industry in the world, the demand for agricultural LED lighting fixtures and their control equipment will reach tens of billions of yuan in the next five years. Plant factories and greenhouse fill light will be the fastest growing LED lighting field with high technical content. The equipment is intelligent and systematic, and it is the focus of the development of the agricultural semiconductor lighting industry. It can be seen that with the increase in the penetration rate of global LED application agricultural lighting, the future market prospect is broad.

Although LED plant lighting has a broad market space, there are still some shortcomings in specific applications. Since LED plant lights need to comprehensively consider factors such as light intensity, spectrum, tube distribution uniformity, efficiency, and heat generation, and plant growth requires specific bands, different varieties, and growth cycles will have different light requirements, so plant factories need to Integrate plant species, growth stages, etc., and adjust the optimal growth curve in a timely manner.

The Analysis of LED Lighting And Health Problems

Previously, relevant experts and scholars have suggested that the blue light in the illumination has a certain weighted damage to the human retina. Recently, the relevant research found that LED lighting has induced health problems, saying that people who work and live in LED white light pollution environment for a long time, the retina and iris will be damaged to varying degrees, the visual acuity drops sharply, the incidence of cataract Up to 45%. It can also cause dizziness and upset, and even symptoms such as insomnia, loss of appetite, depression, physical weakness and the like.

According to optical experts, the reflected light of mirrored building glass is stronger than that of sunlight, and its reflectivity is as high as 82% to 90%. The light is almost completely reflected, which greatly exceeds the range that the human body can bear.

In addition, research papers have pointed out that LED lamps to contain lead, arsenic, and dozens of other dangerous substances. White LED lamps have the least lead content, but there is still a large amount of nickel, a heavy metal that can trigger an allergic reaction. The level of copper found in some LED lamps may pose a threat to the environment. If accumulated in rivers and lakes, it may poison aquatic organisms.
To this end, in response to related issues, we further explore the deep-seated reasons why LED lighting white light is questioned to affect human health and LED lamps are being questioned to bring heavy metal pollution.


The "sin" of LED lighting affecting vision health is not all in white light

Where is the harm of LED white light to human eye health?

First, let's look at the main causes of the wavelengths causing the hazards:
1. Cataract mainly causes damage from 700nm-1400nm red light to infrared light and 290nm-325nm medium wavelength ultraviolet light. It is generally called "infrared-induced cataract" and "ultraviolet-induced cataract", but currently LEDs for lighting basically have no infrared rays and no There is a mid-band ultraviolet ray;
2. Photoinduced keratitis is mainly caused by short-wavelength and medium-wavelength ultraviolet rays of 200nm to 320nm, but these ultraviolet rays are not present in LEDs for illumination;
3. Retinal hazard is mainly caused by photochemical damage of 400nm～500nm blue light, and retinal thermal damage of 400nm～1100nm visible to infrared, but the main effect of retinal thermal damage must be a high power of higher temperature for human eyes in less than 10 seconds. Illumination of lamps, there is basically no infrared light in the LEDs for lighting, and there is basically no high-power LED lamps used in close proximity. It can be seen that there is almost no ultraviolet light or infrared light in the LED lamps currently used for illumination, and the harm of LED white light to the human eye is mainly reflected in the "blue light" aspect.
However, many traditional lighting products, such as high-end lighting and high-power metal halide lamps used in shopping malls and stadiums, have both high-power infrared heat and "blue light", as well as "long-wave, medium-wave, and even short-wave ultraviolet rays." Even the incandescent lamps that people are most accustomed to having a large number of infrared rays, a small number of ultraviolet rays and blue light. White light can be decomposed into red-orange, yellow, green, blue, and purple. It can also be composed of red, green, and blue primary colors. Therefore, blue light is inevitably present in all lighting products.
Secondly, there are a large number of high-intensity infrared rays, ultraviolet rays and blue light in the sunlight. The sun is very strong, and its ground illumination is about a hundred times that of people's reading illuminance specifications. The blue light in the sun is the largest in its spectral power. Therefore, it is not necessary to talk about the blue light retina damage of LED white light to the human eye. After years of controversy and improvement, there is basically no risk of reaching the second class RG2 LED lamps. This kind of RG2 lamps is long-distance direct-view lamps at a long distance. It's perfectly fine, and it will damage the retina when it is close to the light for a long time. In contrast, people who look up directly at the noon sun for more than a second may have retinal damage. From this point of view, the risk of the sun reflected from the mirror surface of the building's curtain wall is relatively high (especially for children and young children who cannot avoid glare) because people do not need to look up too much and their eyes may look To strong reflected light. It can be seen that LED lighting and LED lighting are relatively safe.

In general, to solve the human eye health problems caused by LED white light, we can only return to find out how to suppress the blue light damage to the human eye.

LED lamps cannot be "full" responsibility for heavy metal pollution

Many daily consumer products or their production processes use a lot of heavy metal elements such as nickel and copper. In the past, traditional lighting products also used heavy metal elements such as nickel and copper. For example, fluorescent wires have a large number of conductive wires in the fluorescent lamp. A large number of light sources are copper-plated, copper-plated iron wire, nickel-plated copper wire, nickel-plated iron wire, nickel-plated iron wire, etc. Most of the E27 and E14 lamp caps of energy-saving lamps are made of heavy metal nickel such as iron-plated nickel.
Of course, it is not a good thing to use these heavy metal materials in LEDs and in the production process. Nickel is the most common contact with allergic metals. Therefore, it is necessary to reduce the harm of nickel and other heavy metals to the human body and the environment. In the process of recycling, we must do a good job in environmental protection.

Why LED lights are repeatedly questioned

White light is a common light. Traditional fluorescent tubes and energy-saving lamps are also white lighting, but they are not very prominent for the health problems of the human eye. Why do LED lamps have such a big impact on human eye health? Even with the heavy metal pollution that many traditional lighting fixtures have, LED lamps will be “snapped out” in this respect. In response to the above questions, there are several reasons:
1) The advantages of LED lighting compared to traditional lighting are very obvious, but compared with traditional lighting products, LED still has some defects. For example, 1LED has a small light-emitting area. In the early days, many LED lamps did not undergo diffused light processing, resulting in high brightness and glare; 2 LED luminosity and chromaticity spatial distribution were uneven, resulting in uneven light and color of the illuminated surface; 3 even in the same color gamut 2 LEDs, for example, even if they meet the standard requirements in the 7-step color gamut, but the color difference between them may be obvious; in traditional lighting products, except for metal halide lamps, other lights do not appear; 4 At the same color temperature, theoretically and practically, LEDs are at a greater risk than blue light hazards of traditional lighting products. Especially in the early stage of LED development, LED has low light efficiency and high price. Many LED lighting products use high color temperature LED light-emitting diodes with higher light efficiency than low color temperature LEDs, which is another reason for high brightness and glare.
2) Human cognition and adaptability. The advantages of LED lighting compared with traditional lighting are very obvious, and the technology is developing very fast. The process of replacing traditional lighting with LED lighting is very fast. The difference between LED lighting and traditional lighting does make some people feel uncomfortable for a short time, especially in the early stage of LED lighting development. But after a while, most people have become accustomed to adapting.
3) Because traditional lighting is not a high-level industry, but it involves a lot of people, it is not very concerned by the technical staff. Most of the experts engaged in high-tech do not have the practical experience of traditional lighting, and the technicians engaged in traditional lighting also recognize the LED. Insufficient knowledge, both of which make it difficult to fully and accurately compare LEDs with traditional lighting, and it is difficult to fully understand the shortcomings of LEDs.
4) The early development of LED is still not in place. For example, the most important light efficiency indicators can not reflect higher than traditional lighting. Some of the LED lighting trends are not well understood. Some traditional lighting companies that are in a wait-and-see state may be in their own interests. Various occasions have made some comments that are not conducive to LED, which has produced a profound misleading to the public. At the same time, because there are no standards for initial LEDs, it is quite confusing. Many LED lighting products do have many problems.
 

Based on the above interpretation, LEDs are indispensable for the lighting industry and society. In fact, the human health problems that LED lighting may induce are not exclusive to them. The traditional lighting industry and products also exist, and some are even more serious. With the advancement of LED lighting technology, it is believed that such problems will be solved.

The Internal Relationship Between Light and Plants

Light and Photosynthesis

Photosynthesis is the process by which green plants absorb light energy, assimilate carbon dioxide and water, produce organic matter and release oxygen. Photosynthesis produces mainly sugars and stores energy. Light energy is the energy source of photosynthesis in plants, but plants absorb different amounts of light at different wavelengths, and their photosynthetic products are different. Studies have shown that under the irradiation of red light, leaves form a large amount of carbohydrate, with less protein. When the blue light is irradiated, the carbohydrate decreases while the protein content increases.

Light saturation phenomenon and light compensation point. Photosynthesis is a photobiochemical reaction. Within a certain range, the photosynthetic rate increases with the increase of light intensity, but beyond a certain range, when the light reaches a certain intensity, the photosynthetic rate does not increase. This phenomenon is called light saturation. The light saturation point of the heliophytes is higher than that of the heliophytes. Because when the group leaves are flourishing, the external light is very strong, reaching above the light saturation point of single leaf, while the light intensity inside the group is still below the light saturation point, the middle and lower leaf leaves make full use of the transmission light and reflected light, the group light rate will rise.

In addition, as the light decreases, the rate of photosynthesis gradually approaches the rate of respiration, reaching a point at which photosynthesis equals the rate of respiration. In the same leaf at the same time, the CO2 absorbed by the photosynthetic process and CO2 released by the respiration process is equivalent in an intensity of light, which is called the light compensation point. At this point, the photosynthetic accumulation and absorption of organic matter equal, the plant do not grow. Therefore, in order to ensure the normal growth of crops, the light intensity must be greater than the light compensation point. So how do you make the light more intense than the compensation point?

(1) Extended Photosynthetic Time

Lengthening photosynthetic time is to maximize the use of light time and improve the utilization rate of light energy. The specific measures are as follows:

1. Increase the multiple seed index. It means to increase the ratio of the harvested area of crops to the cultivated area in the whole year. Specific practice is the four seasons rotation, reasonable interplanting. In one year, various crops are skillfully matched, so as to make better use of light energy in time and space, shorten the idle time of fields and reduce the rate of light leakage.

2. Extend the growth period. On the premise of not affecting the farming system, the crop growth period should be extended appropriately.

3. Supplement of artificial light. Under the cultivation of small area, when the sunlight is insufficient or the sunlight time is too short, it can be supplemented by artificial light. LED growing lights are the ideal artificial light source, and the spectral composition is similar to that of sunlight.

《Why Does The LED Grow Lights Need to Dissipate Heat?》

《The Analysis of LED Grow Lights's Market Growth》

《The FAQ of LED Grow Lights》

(2) Increase Photosynthetic Area:The photosynthetic area is the green area of plants, mainly leaf area, which has the greatest impact on yield and is also an easy to control aspect.

1. Reasonably close planting. It mainly deals with the relationship between the group and the individual, the species is too sparse, the individual develops well, but the group is not fully developed, and the light energy utilization rate is low. If planted too tightly, the lower leaf receives less light and becomes a consuming organ below the light compensation point, the photosynthetic productivity will decrease and it will also decrease.

2. Change the plant type. High yield cultivars of good plant type were selected, that is, short stem, straight and thick leaf, dense tillering. In other words, it can increase the density of planting, increase the photosynthetic area, resist fertilizer, make full use of light energy and improve the utilization rate of light energy.

Improve photosynthetic efficiency. Good ventilation in the field, ensuring the supply of CO2, or increasing the concentration of CO2 in the field can improve the photosynthetic efficiency per unit area. At present, the commonly used method is, the first is to adjust to local conditions, to ensure ventilation. Second, organic farm manure and ammonium bicarbonate fertilizer were added, which not only increased nitrogen but also increased CO2 concentration in the field. The third is to use photorespiration inhibitors to inhibit photorespiration and improve light and ability.

The Relationship Between Light and Plant Growth

Generally speaking, the growth and development of plants are carried out under sunlight. Different spectra have different effects on many kinds of light reaction phenomena, such as photosynthesis, growth, development, a formation of chlorophyll, phototropism, and induction of photomorphogenesis.

(1)The effect of light on the growth of vegetative organs.

The seedling development is controlled by light. Seeds of cereal crops, sheaths and mesocotyls sown in the soil elongate until the light is seen. When the seedlings see light, the curly leaves open. Light inhibits stem elongation. Light also inhibits root growth of various crops, and the intensity of light is positively correlated with root growth inhibition.

(2) Phototropism of plant growth.

The ability of a plant to bend in the direction of light is called phototropism. If the leaves can be extended as far as possible in the best use of light energy position. The reason for the phototropism is that the light from one side can cause the auxin to be transported laterally to the backlight side, thus making the auxin on the back side more and the cell elongation is intense, so the plant grows to the light and bends. In addition, the study found that it was a short-wavelength light that played a role in the direction of light, while the red light was ineffective.

(3)The effects of sunlight on flowering and dormancy of plants

1. Effect of sunshine length on plant flowering. Plant flowering has photoperiod, and the length of sunlight has a decisive influence on the length of time from vegetative growth to flower stem formation. Studies have shown that the photoperiod of plant flowering, during the photoperiod and dark period, is the dark period. That is, short sunlight plants must exceed a critical dark period to form flower buds; Plants with long sunshine must be shorter than a critical dark period before they can bloom. The flash test proves the importance of the dark period.

2. Effects of light on plant dormancy. Many studies show that autumn leaves and winter dormancy of temperate plants are related to the length of sunshine. Short sunlight can push the plants into hibernation. For example, poplar trees, after being given a few days of short sunshine, will form a terminal bud even if the temperature is still quite high. If the short sunshine treatment continues (the temperature condition remains unchanged), the leaves will no longer grow, then gradually fade off and enter deep dormancy. If treated with long sunshine again, the plant can continue to grow without going into hibernation. Tree species such as acacia and poplar also reacted to the short sunshine. Therefore, in the introduction work of the northern botanical garden, short sunlight can be used to induce early dormancy of trees and enhance the ability to resist cold and winter.


(4)Light plays a certain role in inducing morphological formation, phototropism, and pigment formation.

For example, the blue-violet and blue-green light in visible light can inhibit the elongation of plants, thus causing plants to form short forms. Blue, blue and violet light can cause the sensitivity of plant phototropism and promote the formation of anthocyanins and other plant pigments. Blue light can activate the enzymes that assimilate CO2 in photosynthesis. Ultraviolet light can inhibit the growth factor formation and stem elongation. Alpine plants stem dwarf, leaf surface shrinking, stem leaves rich in anthocyanin, and so on, and high mountain blue, purple, green, such as shortwave light and more ultraviolet light.

In recent years, the application of colored films in agriculture has been more and more extensive. For example, compared with the natural color film, the seedling and root system of the light blue film are stronger, the seedling and root system of the former are quick to survive, the tillering is early and many, and the content of various nutrients of rice is higher. 


Therefore, the correct understanding of the relationship between light and plants is more conducive to the improvement of crop quality and yield.

The Analysis of LED Grow Light's Market Growth

At present, the competition in the global LED general lighting market is becoming increasingly fierce. The horticultural lighting industry may be a new opportunity for the LED industry to use LED technology to develop high value-added products to obtain greater profit margins. Due to global climate change, residential and industrial construction, agricultural land reduction, rapid population growth, food security, and other issues are prominent, resulting in urban food is difficult to meet people's needs, and LED horticultural lighting can solve these problems. LED gardening lighting is not restricted by the natural environment. The all-weather and efficient production method can not only greatly improve the land utilization rate, but also solve the increasingly prominent food safety problems, which is of strategic significance for solving the food problems of various countries.

With the continuous improvement of LED horticultural lighting technology, its application fields will become more and more extensive, including greenhouses, plant factories, family farming and so on. According to statistics, the CAGR of the LED horticultural lighting market will reach 27% from 2015 to 2020. Among them, the increase in food demand is expected to reach 59%-98% by 2025.


Compared with traditional plant lighting technology, LED technology has lower power consumption and can save a lot of energy costs. Moreover, LED-based lighting systems generate less heat and enable the illumination of crop-intensive areas. LED lights are installed near the bottom crops that are relatively unlit by surface crops, improving output consistency and increasing crop yields. Many experts said that LED plant lighting technology can not only improve efficiency, increase crop yield, but also achieve higher profits for customers. Adjustable LED solutions are also available to support lighting needs at all stages of the plant's growth cycle. The adjustability of the light allows farmers to adjust the light output to find the ideal proportion of light to maximize yield and grow a variety of crops.

With the combination of LED technology and plant lighting, many companies have also discovered this opportunity. But blind entry is not good for business and industry. At present, there are two types of enterprises in the field of LED plant lighting. One is to provide complete solutions including lamps, nutrient solution ratio, vertical farm facilities, intelligent management equipment, etc. The second is to focus on optoelectronic devices and launch special wavelengths according to different plants. LED business. New companies will find the right position, measure the input cost and return expectations, and choose the direction and operation mode.

《5 Ways To Maintain LED Lights》

The Problems And Solutions For Cannabis Cultivation

Phosphorus Deficiency

Phosphorus is an essential nutrient that it’s very important during flowering. It also helps with root and stems growth. It allows your plant to perform photosynthesis or convert light into energy. It assists at the beginning of your plant’s life during the germination phase and also is useful during your plant’s reproductive phase.

Signs of Phosphorus Deficiency
1. Leaves turn to a blue-green color
2. Lower leaves turn yellow and brown
3. The stem can turn a purple color
4. Leaves have blotches of brown or blue
5.Slow growth
6. Affected leaves start to curl
7. Lower leaves begin to die

Solution
1.Adjust pH to Correct Range
·In soil, phosphorus is best absorbed by the roots in the 6.2 - 7.0 pH
·In hydro, phosphorus is best absorbed by the roots in the 5.5 - 6.2 pH range
2.Make sure the temperature in the right range
Plants are comfortable with the room temperature, when it lower than 60°F (15°C), as well as large temperature swings, can make it harder for the plant to absorb phosphorus, it will cause phosphorus deficiency.
3.Give the Right Nutrients, do not overdose
If you are sure it’s phosphorus deficiency, you can add extra phosphorus to your plants, or you can use nutrients which include phosphorus, but do not over does.
4.Take Good Care of the Roots
Phosphorus deficiency will also cause root problem, proper watering and right PH will help to protect the root system to recover.

Tobacco Mosaic Virus

The tobacco mosaic virus is very fatal for many plants, like tomato, pepper, eggplant, tobacco, spinach... and the virus infection causes light and dark green mottled areas on the leaves. The dark green areas tend to be somewhat thicker than the lighter portions of the leaf. The leaf mottling is seen more easily if the affected plant surface is partially shaded. Stunting of young plants is common and often is accompanied by a distortion and fern-like appearance of the leaves. Older leaves curl downward and may be slightly distorted. Certain strains of the virus can cause a mottling, streaking, and necrosis of the buds. Infected plants are not killed, but they produce poor quality buds and low yields.


Solution
Virus diseases cannot be controlled once the plant is infected. Therefore, every effort should be made to prevent the introduction of virus diseases into the garden. Sanitation is the primary means of controlling virus diseases. Infected plants should be removed immediately to prevent the spread of the pathogens. The use of tobacco products during cultural practices should be avoided to prevent inoculation of plants with the tobacco mosaic virus. Those people using tobacco or working with infected plant material should wash their hands thoroughly in soapy water before handling your plants.

Spider Mites

Spider mites are not insects but are more closely related to spiders. Most spider mites have the ability to produce a fine silk webbing. They have tiny mouthparts modified for piercing individual plant cells and removing the contents. This results in tiny yellow or white speckles. When many of these feeding spots occur near each other, the foliage takes on a yellow or bronzed cast. Once the foliage of a plant becomes bronzed, it often drops prematurely. Heavily infested plants may be discolored, stunted or even killed. Web producing spider mites may coat the foliage with the fine silk which collects dust and looks dirty.


Solution
Early detection of spider mites, before damage is noticed, is VERY important. The tiny spider mites can be detected only by a full and thorough leaf inspection (on both sides of the leaf). you can use 1 tablespoon of bleach to 1 gallon of 95°F, pH balanced, water in a spray bottle.) or use a miticide with Abamectin or lindane in it. That seems to work best. There are insect predators that can help in providing some control but this does not mean 100% eradication and in a consumable crop that is what we are after. The predator mite can help to control them if chemical sprays are not your thing.

Heat Stress

Plants are very sensitive to temperature, no matter indoor grow or outdoor grow when the temps are so high, low humidity or light too close the plants, the plants will have heat stress problem.


Sign of Heat Stress
Plants leaves will become yellow or brown spot, When the heats get too high, the edges of the serrated leaves will begin to curl up and the leaves will begin to “cup”

Solutions
Buying a temperature monitor to monitor the temps, according to the monitor to adjust the temps to help plants keep in a comfortable environment. For the indoor grow, a good ventilation system is very important, keep the light don’t close to your plants.


Iron Deficiency 

Iron is a necessary nutrient that helps plants grow tissues.And iron is needed to help enzymes function well or for chlorophyll to synthesize properly.

Signs of Iron Deficiency
1.Yellowing outside the veins of the plants' leaf, veins remain green
2.Young leaves show yellow from opposite tips of the leaf
3.Slow growth
4.Bigger leaves will start to yellow between the veins of the leaf
5.Leaves will start to show signs of burnt tips
6.Eventually, the leaf will fall off
7.Thin bud development

Solutions:
1. Adjust pH to Correct Range
·In soil, iron is best absorbed by the roots in the 6.0 - 6.5 pH range
·In coco coir or hydro, iron is best absorbed by the roots in the 5.5 - 6.5 pH range
2.Most plants growers don't need to add more iron in response to an iron deficiency，usually cal-mag supplement contains iron, so do not overdose.
3.Give proper water schedule, do not over water,the root system is important for plants to recover from iron deficiency.

Zinc Deficiency

Zinc is responsible for enzyme function and chlorophyll in the plants, and which affects the strength of all parts of the plant such as the stems, branches, stalks, and leaves.

Signs of Zinc Deficiency
1.Yellowing between the veins, in new and young leaves
2.New Leafs are small and thin and appear twisted
3.New leaf growth is pale yellow-green
4.Stems fail to grow and stretch leaving minute leafs
5.The tips of leaves appear burnt
6.Internode spacing is reduced
7.Growth is stunted
8.Buds are thin and light to the touch
9.During flowering, buds will start to twist
10.End yields are small

Solutions:
1.Adjust pH to Correct Range
·In soil, zinc is best absorbed by the roots in the 6.0 - 6.5 pH
·In hydro, zinc is best absorbed by the roots in the 5.5 - 6.0 pH
2.Give the Right Nutrients, not overdose
3.Take Good Care of the Roots, make sure proper watering system will help plants grow healthy and avoid a host of problems.

Magnesium Deficiency 

Magnesium is a mobile element, Magnesium deficiency usually starts in the middle of the plant and spreads to the younger leaves. Leaves turning yellow, or even white, with the veins remaining dark green, is the best indicator of Mag deficiency.Magnesium can be easily absorbed by plants when the PH range of is 5.0-7.0, also other factors may reduce or lock-out the mag uptake, such as a permanent humidity, low temperatures, or acid and cold substrates.

Solution:
As Calcium, magnesium deficiency usually appear together, so usually get a Cal-Mag supplement
1.Adjust the PH level:
·In soil, magnesium is best absorbed by the roots in the 6.0 - 7.0
·In hydro, magnesium is best absorbed by the roots in the 6.0 - 6.5 pH range
2.Adding more magnesium to your growing system, but not overdone,otherwise will also got trouble.
3.Flush your system with clean, pH'd water that contains a regular dose of plant-friendly nutrients that includes magnesium. Such as: spray with a 2 percent Epsom salt.

Calcium Deficiency

Calcium is important for the plant's growth, it helps provide structure to the plant, especially under LED growing.

Signs of Calcium Deficiency
1.Upper leaf issues show spotting first
2.Lower leaves curl and twist
3.Yellow, brown spots appear on leaf and tips
4.Stunted growth
5.Flower development is slow
6.Brown or dark spots on leaves
7.The random pattern of spots
8.Stems start to become weak
9.Roots become weak or begin to die

Solution：
Correct the PH level for your growth.Soil, 6.0 - 7.0 pH range. Hydro or coco coir, 5.5 - 6.5 pH range.
Add extra calcium, some growers use tap water with great success! Most tap water contains calcium and magnesium in small quantities.

5 Ways To Maintain LED Lights

LED Lights Are Vulnerable To Damage

1. Low-quality LED lamps are more prone to failure. Therefore, when buying, we should identify the brand manufacturers with quality assurance.

How to buy LED lights? Read the following passage:
《Xinjia Teaches You How To Choose The Home Lighting》

2. LED lights that are not properly used according to the product instructions are prone to failures and hidden dangers. So when buying, must confirm the use method of the lamp with the salesperson.

3. When used, an excessive current exceeding the rated current of LED lamps will cause the danger of burning or breakdown of some components in LED drive power supply.

4. The problem of "water fog" of LED lamps, such as candle lamp, bulb lamp, projection lamp, etc. LED lamps are generally assembled from several different materials, such as metal for heat dissipation, plastic for lampshade, acrylic, etc. The lamps and lanterns can produce certain quantity of heat in the work, the heat expansion coefficient of different material is different, after using for a long time can produce a crack in the joint of different material and air inlet; When used in an environment with high humidity, the temperature inside and outside of the lampshade is different, and the heated gas inside the lampshade reaches the place of the lampshade and becomes cold. If the gas contains more water vapor at this time, the phenomenon of water mist and water bead will be generated, and this phenomenon will disappear after continuous lighting for some time. Therefore, humidity environment is also an important factor affecting LED lamp life.

The Method of LED Lights Maintenance

1. After buying back the LED lamp, don't be in a hurry to install it. Read the installation instructions carefully and install the lamp step by step according to the installation instructions.

2. Do not change the structure of the lamp during cleaning and maintenance, and do not change the components of the lamp at will. After maintenance, install the lamp as is, and do not leak or mistaken install the parts of the lamp.


3. Try not to use frequent switches when using lamps. Although the number of resistance switches of LED lights is about 18 times that of ordinary fluorescent lamps, too frequent will still affect the life of electronic components inside LED lights, thus affecting the life of lamps.

4. It should be noted that, except special LED lamps, ordinary LED lamps should be avoided to use in a humid environment. The too humid environment will affect the LED power supply of electronic components, electronic components affected by moisture, lamp life shortened. Accordingly, moistureproof is one of the key points that lamp ACTS the role of maintaining, especially the LED lamp of a toilet, bathroom and kitchen headlamp, want to install a moistureproof chimney, in order to prevent moisture to invade, avoid occurrence rust to erode damage or leakage of the electric short circuit.

5. The LED lamp should not be cleaned with water. Generally, it can be wiped with a dry cloth with water.

Analysis of The Technical Needs of Plant Lighting Users

Types of Plant Lighting
 
At present, the types of plant lighting include an incandescent lamp, a halogen lamp, fluorescent lamp, high-pressure sodium lamp, and LED lamp. LED, with its advantages of high luminous efficiency, low heat, small size, and long life, has obvious advantages in the field of plant lighting. According to the data analysis reported, it is estimated that the size of LED growth lamp will account for 61% of the plant lamp market in 2020.


Current Situation And Development Trend of LED Growing Lights Market
 
At present, the plant lighting market is mainly concentrated in the Middle East, the United States, Japan, China, Canada, the Netherlands, Vietnam, Russia, South Korea, and other regions. Since 2013, the global LED plant lighting market has entered a period of rapid development. According to statistics, the global LED grow lights market in 2014 was $100 million, and the market in 2016 was $575 million, forecast to grow to $14.24billion by 2020, and the annual compound growth rate is over 30%. The global plant factory plant lamp market is developing rapidly, and the scale is predicted to be as high as 19120000㎡  by 2020.

 
The Application Field of Plant Lights
 
The field of plant lighting, as one of the fields of agricultural lighting, has developed rapidly in recent years. Light plays an important role in the growth and development of plants in two aspects: as energy, it participates in the photosynthesis of plants and promotes the accumulation of plant energy; and as a signal, it regulates the growth and development of plants, such as the growth of buds, flowers, and stems. From this perspective, plant lighting can be divided into growth lighting and signal lighting, while growth lighting can be divided into full artificial light growth and supplementary light from the use of artificial light. Signal lighting can also be divided into buds, flowering, colored lights and so on. From the field of application, the field of plant lighting mainly includes seedling (including tissue seedling and seed seedling), garden landscape, plant factory, greenhouse planting and so on.
 
User's Technical Requirements of Plant Lights
 
Plant lighting is a comprehensive and cross-disciplinary industry, and the growth of plants is also a result of multiple factors. The technical requirements of plant lighting users concern not only the lighting part but also other factors. The technical requirements of plant lighting users will be analyzed from two perspectives below.
 
1.Analyze user technical requirements from the perspective of the patent layout
 
According to statistics, the first five IPC technical categories of patents applied in the application field of LED plant lighting are shown in the figure, respectively
 
(1) f21y101/02: involving miniature light sources, such as light-emitting devices or lighting systems of light-emitting diodes;
 
(2) a01g9/20: use light to grow flowers, vegetables or rice in an enabling breeding ground;
 

(3) F21s2/00: non-portable lighting device or its system with modular structure, etc.;

(4) A01G7/04: electric or magnetic treatment of plants to promote their growth. From the perspective of patent layout, the improvement of the miniature light source, lighting system, planting scheme, structural modularization, intelligent device, and system silly are the trends of patented layout, which largely reflects the technical requirements and trends of users of plant lighting.

 
 
2.Analyze from the user's perspective
 
The acceptance of plant lighting users to the industry has greatly influenced the development of the industry. For users of plant lighting, the cost of investment and use is the key issue.
 
2.1The Cost of LED Grow Lamps
 
The cost of LED lamps is directly related to the user's investment cost. Although the energy saving and spectrum advantages of LED lamps are obvious, the price of LED lamps is higher than that of other plant lighting lamps. Take cannabis lamps, for example, the same 600w lamp, the high-pressure sodium lamp plant lamp set price is about 300USD, and the LED plant lamp is about 2000USD. Most customers are more willing to start with small power lamps.
 
In the cost of lamps and lanterns, besides the outer casing of the lamp, drive cost, the cost of the lamp bead is compared with the ordinary lamp bead, the price is higher. Take the 2,835 lamp beads of 0.2w for example, the price of the plant lamp beads is about 4-7 times that of the general lamp beads. Of course, the price trend of LED beads is decreasing year by year, and the price of materials such as substrate materials, phosphor powder, and epitaxial wafers is decreasing year by year. The cost of chip manufacturing is also decreasing with the increase of production efficiency (upgrade of 2-inch to 4-inch wafers). The cost of the beads will fall to about 40 percent in 2015 in 2020, according to a report by the chi research consultancy.
 
2.2 The Using cost of LED plant lamps
 
Power cost and power performance are the main concerns of every plant lamp user. Power performance refers to the ratio of power input to output per unit of consumption. The output here is to point to output and quality two respects.
 
2. 2. 1 Light
 
As one of the main factors affecting plant growth and development, light spectrum, light intensity, and photoperiod affect plant growth and development. The light effect is closely related to power performance.
 
(1) spectrum
 
Wavelength range of 300 ~ 800 nm radiation called plant physiological active radiation (physiologically active radiation), but UVB (280-320 nm) and UVc (220-280 nm) band for plant growth and development of the secondary metabolites (produce). On the wavelength type of plant lamp beads, Osram introduced 450nm, 660nm, 730nm, 617nm, 623nm and 6000k white lamp beads. EDIson launched 39-410nm, 415-435nm, 450-460nm, 520-535nm, 585-600nm, 620-630nm, 660nm and 725-745nm light beads. On the monochrome lamp bead, the physiological effective radiation wavelength of the plant is basically covered, plant lamp manufacturer produces different applicable spectrum by different lamp bead combination. However, lamp beads in the UV band, or on the basis of technological reasons, or on the basis of cost, have not been widely used in plant lighting products like other wavelength lamp beads.
 
Although the spectrum can be diversified by a monochromatic lamp bead array, or by chip excitation phosphors. However, different plant species, different stages (seedling growth, vegetative growth, reproductive growth, flowering induction), and different application scenarios have different spectra of requirements.
 
There are many kinds of plants for users of plant lighting, such as red quinoa, salad lettuce, diced vegetables, dragon fruit, passion fruit, strawberry, tomato, cantaloupe, rose, okra, dendrobium, clematis, tissue seedling, tobacco seedling, sweet potato seedling, okra, hemp, and succulent plants. Their recognition and differentiation of spectra are not necessarily professional, but they are primarily concerned with the data of planting effect. Some users are interested in plant lighting products that mimic the sun's rays and think the spectrum similar to the suns would be more widely applicable. This is the compromise made by customers to increase energy consumption when the diversity and precision of the spectrum fail to meet customer demands.
 
(2) Light Intensity
 
The effect of light intensity on plant growth has two points, the compensation point of light and the saturation point of light. For users, the saturation point of light is not necessarily the best light intensity in the production application, which needs to consider the growth rate of plants and balance the production cost. Different crops and different stages have different needs for light intensity. The user needs the plant lighting manufacturer to provide the best light intensity and the combination and suspension mode needed to achieve this light intensity, and most plant lighting manufacturers do not have the technical reference.
 
In light intensity, the demand for plant lamp as a signal is lower than that of growth lamp as energy. As a signal lamp, its optimum light intensity is much lower than that of growth lamp, and its action light intensity (PPFD) is at 3-30 mmol/m2. S.
 
(3) Luminous Effect
 
Luminous efficiency is the ability to convert electrical energy into luminous energy. The higher the light efficiency, the higher the power performance and the lower the power cost. The plant lighting user is concerned with the full lighting effect (units: pressure mol/J). As a plant lamp supplier, the lighting effect of the plant lamp should be improved by the design of the lamp. Red light (660nm) beads are available for up to 3. 17 moles/J, and blue light (450nm) at 2. 5 moles per J. And in the purple light band light pearl effect is low. Mixed color lamp bead is the highest luminous effect is 2. 5 moles per J.
 
(4) Use of Light
 
Plant lighting, which replaces sunlight, is fully controllable. The illumination time, intensity and spectrum of a day are controllable. How to improve power performance by controlling the way light is a problem that most users of plant lighting pay attention to. Total photosynthetic radiation (DLI) refers to the total amount of sunlight accumulated by plants in 24 hours per unit area (per square meter). Plant lighting users, especially plant factory users, pay more attention to the "saturation value" of total photosynthetic radiation of plants to avoid the waste of light energy and electricity.

 
 
2. 2. 2 System Scheme
 
The characteristics of high input and high production cost require the high efficiency of crop production in plant factories. Different from the traditional planting environment, the environmental factors of plant factories are fully controllable, which is also the basis of the efficient production of plant factories. At present, the industry mainly realizes the efficient production of plant factories from the intelligent management system, expert planting technology, and automatic operation platform.
 
Intelligent management systems, such as plant intelligent control technology based on Internet of things, plant plant plant monitoring system based on PLC, plant control system based on an embedded platform. Through these control systems, online detection, remote access, program update and networked intelligent control of plant factory temperature, humidity, light, co2 concentration, nutrient solution Ec, pH, Do and other elements can be realized.
 
Expert planting techniques. The plant factory is different from the traditional planting mode. No matter it is someone from other professional fields, or someone from traditional agriculture, investing or managing the plant factory, the expert planting technical requirements and guidance is essential. The growth and development of plants is the result of the interaction of wind, light, water, nutrients, gas, and bacteria. At present, there are research data on photo temperature coupling, photo temperature CO2 interaction and nutrient element coupling, while more interaction schemes are rarer. These systems are all designed on the basis of interaction of growth factors, but more planting data is needed to support the formation of export schemes. To save labor costs, automated operating systems are also the focus of the industry
 
Others
 
In addition, plant lighting users have corresponding technical requirements for the waterproof level, luminescence Angle, and heat dissipation system of lamps, lamp life, spectral effective life, and light decay.
 
 
With the maturity of LED lighting technology and the decline of LED cost, many enterprises are moving from the fiercely competitive general lighting market to the field of plant lighting, and the technical demand for plant lighting will become increasingly clear.

Pay Attention To The Following Points: Say Goodbye To Huge Electricity Bills!

Inspect Lighting Regularly

1. Regularly clean lighting lamps:

When lamps are not cleaned for a long time, dust accumulates gradually, such as lamp tube and reflection cover, resulting in lower output efficiency, so lamps should be cleaned at least every three months to maintain output efficiency.

2. Regularly replace the old lamp tube:

Incandescent bulbs and daylight bulbs use 80% of their life, the output beam is about 85%, so it should be replaced before the end of their life, reducing waste. For a large number of lighting households, the regular replacement of light source is particularly important. It can not only save labor cost and improve indoor illumination but also save electricity cost, economic and environmental protection.


Take Effective Lighting

1. Selection of local lighting

If you use comprehensive lighting to accompany reading, drawing, makeup... Such a specific activity or job is a waste of electricity. Accordingly, to the vision activity that needs higher illuminance, need to use a reading lamp, desk lamp to wait to serve as local lighting only commonly, provide need illuminance can.

2.Proper illumination

All places have their proper illumination, over and below are inappropriate, too high illumination waste electricity, low illumination is impaired vision health, affecting work efficiency.

Choose different lights at different positions. See this article for details:
《Xinjia Teaches You How To Choose The Home Lighting》

Use Natural Light Sources

1. Daylight utilization

I have good daylighting to an average household, can save electric bill up to 50% above in illume respect. On a clear day, open doors and Windows more often to let more sunlight into the room can make the room brighter. Bright lighting not only makes people happy but also contributes to energy conservation and environmental protection.

2.Building lighting

(1) clear glass is used as the window material to obtain the more abundant natural light source.

(2) the high window design can provide deep and uniform daylight light.

(3) energy saving effect can be achieved by adopting auxiliary daylight light such as light guide plate and light guide tube.

(4) the light color is adopted for indoor wall and curtain, which can improve the diffuse light effect and save electric energy.

(5) keep window glass clean to improve the lighting effect.


Use of Distribution And Control Systems

1. Reasonable lighting and switch circuit

Configuration is not reasonable lamps and lanterns and loop configuration, will cause electric energy to waste, for instance will lean window area lamps and lanterns of area of area of window and do not lean window to become same switch loop repeatedly, if want to close when being in daylight enough, when leaning window area lamps and lanterns, will cause not lean window area illuminative inadequacy. The following items should, therefore, be given priority in the design of lighting distribution systems:

(1) Each independent space should have its own switch.

(2) The larger living room should be divided into several areas according to the attributes of the space so that each area can independently control the lamps and lanterns.

(3) Large peripheral and core areas shall be independently controlled.

2. Automatic control of the lighting system

Lighting system adopts automatic control mode, which can eliminate energy loss caused by human negligence. The control mode is as follows:

(1) Provide timing control for specific space and working time.

(2) Use various sensor sensing lines, a human body, etc., or open and close doors to activate or close lamps (solar energy automatic sensing lamps can be used in courtyards).

(3) Use the daylight automatic sensing system to adjust the output of the light source and the action of turning on and off, so as to make full use of natural light to save electricity.


Replace Inefficient Lighting

LEDs consume a quarter as much energy as CFLs and a tenth as much as incandescent bulbs. And the LED has a lifespan of 25,000 hours, three to five times that of energy-saving lamps. Now the LED lamp has gradually replaced the lamps with the same function, and its advantages in energy saving and life are obvious. The picture below is a good example of how LEDs can save money.
