LED Light
LED (Light Emitting Diode), a solid-state semiconductor device capable of converting electrical energy into visible light, can directly convert electricity into light. The heart of the LED is a semiconductor wafer. One end of the wafer is attached to a holder, one end is the negative pole, and the other end is connected to the positive pole of the power supply so that the entire wafer is encapsulated by epoxy resin.
The LED lamp is an electroluminescent semiconductor material chip, which is cured with silver or white glue to the bracket, and then connected to the chip and the circuit board by silver wire or gold wire, and sealed with epoxy resin to protect the inner core wire. Function, finally install the outer casing.
Energy-Saving Lamp
Energy-saving lamps, also known as power-saving bulbs, electronic bulbs, compact fluorescent lamps, and integrated fluorescent lamps, are lighting devices that combine fluorescent lamps with ballasts (ballasts).
The Comparison of LED Lights And Energy-Saving Lamps
1.Technical Comparison
The working principle of the energy-saving lamp is mainly to heat the lamp filament through the ballast, so that the filament starts to emit electrons, and the transition produces ionization, thereby emitting 253.7nm ultraviolet light, and the ultraviolet light excites the phosphor to emit light, because the temperature of the filament is 1160K when the fluorescent lamp works. Left and right, the temperature of the incandescent lamp is much lower than 2200K-2700K, so its life has also been greatly improved, reaching more than 5,000 hours.
The LED lamp is formed by series or parallel connection of LED lamp beads. These LED lamp beads are composed of light-emitting diodes. Under the action of the integrated circuit chip, the AC 220V power supply is converted into DC power with a voltage and current matching with the LED set. Meet the requirements of the LED lamp bead assembly, so that it can normally emit light.
2.Brightness (light flux) Comparison
Comparing the brightness of LED lights and energy-saving lamps, we will see the following data:
1W LED light = 3W energy saving lamp (CFL) = 15W incandescent lamp
3W LED light = 8W energy saving lamp (CFL) = 25W incandescent lamp
4W LED light = 11W energy saving lamp (CFL) = 40W incandescent lamp
8W LED light = 15W energy saving lamp (CFL) = 75W incandescent lamp
12W LED light=20W energy saving lamp (CFL)=100W incandescent lamp
We can see that LED lamps are much higher in brightness (light flux) than energy-saving lamps and ordinary incandescent lamps.
3.Life Comparison
The life of a typical LED lamp can be used for more than 50,000 hours, and some special LED lamps can reach 100,000 hours. Of course, the life of the LED lamp is determined by the chip and the driving factor. However, since the LED lamp does not have the problem of the filament being blown, the life of the LED lamp is much higher than that of other lamps.
The life of a general energy-saving lamp is about 5,000 hours, and it has reached more than 8,000 hours. That is, the energy-saving lamp needs to be replaced after one year.
In contrast, we can see that LED lights can be replaced after more than five years, which greatly saves the cost of replacing the bulbs.
4.Energy Saving Comparison
Who is more energy-efficient in LED lights and energy-saving lamps? We know that energy saving and high life have always been the two characteristics of LED products. How much energy saving is LED light compared with energy saving lamps?
In the case of the same luminous flux, one LED lamp consumes only 1/10 of the energy of the incandescent lamp and 1/4 of the energy-saving lamp. In home lighting, 10W LED lights use 100 hours, only consume 1 degree, far better than energy-saving lamps.
5.Security Comparison
In terms of safety, there is no doubt that LED lights still outperform energy-saving lamps. Since the energy-saving lamp contains heavy metals, it causes heavy metal pollution when the lamp is broken, so there is a hidden danger in terms of safety. Since the LED lamp is composed of a light-emitting diode, there is no such danger. Due to technical reasons, LED lamps are less susceptible to damage than energy-saving lamps, and consumers do not have to worry about damage caused by lamp or bulb rupture.
Analysis of The Advantages And Disadvantages of LED And Energy-Saving Lamps
LED Lamp Advantages:
1. Energy saving: The energy consumption of white LEDs is only 1/10 of that of incandescent lamps and 1/4 of energy-saving lamps.
2. Longevity: life expectancy of up to 100,000 hours, for ordinary home lighting can be described as "once and for all."
3.Can work in the high-speed state, energy-saving lamps if the frequent start or turn off the filament will be black and quickly broken.
LED Disadvantages:
High starting cost, poor color rendering, low efficiency of high power LED, constant current drive (requires dedicated drive circuit).
Energy Saving Lamp Advantages:
1. Compact structure and small size.
2. The luminous efficiency is high at 60Lm/w, and the power saving is over 80%, saving energy.
3. Can directly replace incandescent bulbs.
4. Long life, 6 to 10 times the incandescent lamp.
5. The inner wall of the tube is coated with a protective film and the triple spiral filament can greatly extend the service life.
Energy-Saving Lamps Disadvantages:
1. Mercury pollution in the production process and after use. At present, countries around the world pay considerable attention to mercury pollution.
2. Because it is a glass product, it is easy to be broken, it is not convenient to transport, and it is not easy to install.
3. Its power consumption is large.
4. Easy to damage, short life, energy saving does not save money.
Based on the above points, it is not difficult to find that with the development of the times and the concept of energy conservation, people are gradually gaining popularity. More and more energy-saving lamps will be replaced by LED lights.
