LED lamp is a light-emitting diode, which uses solid semiconductor chip as light-emitting material. Compared with traditional lamps, LED lamp is energy-saving, environmental protection, color rendering and response speed is good. [3]
（1） Energy saving is the most prominent feature of LED lamp
In terms of energy consumption, the energy consumption of LED lamps is one tenth of that of incandescent lamps and one fourth of that of energy-saving lamps. This is one of the biggest features of LED lights. Now people advocate energy conservation and environmental protection, and it is precisely because of this feature of energy saving that led lamps are widely used, which makes LED lamps very popular. [3]
（2） It can work in high speed switch state
We usually walk on the road, will find that each LED screen or screen is unpredictable. This shows that led lights can be switched on and off at high speed. However, we usually use incandescent lamps, it can not reach such a working state. In ordinary life, if the number of switches is too much, it will directly lead to filament breakage. This is also an important reason for the popularity of LED lights. [3]
（3） Environmental protection
LED lamp does not contain any mercury and other heavy metal materials, but the incandescent lamp contains, which reflects the environmental characteristics of LED lamp. Now people attach great importance to environmental protection, so there will be more people willing to choose environmentally friendly LED lights. [3]
（4） Fast response
LED lamp also has a prominent feature, that is, the reaction speed is relatively fast. As soon as the power is turned on, the LED lights will be on. Compared with the energy-saving lamp we usually use, its reaction speed is faster. When turning on the traditional light bulb, it often takes a long time to illuminate the room, and it can only be lit up after the bulb is completely heated. [3]
（5） Compared with other light sources, LED lights are more "clean"
The so-called "clean" does not mean that the surface and interior of the lamp are clean, but the lamp belongs to a cold light source, which will not generate too much heat and will not attract insects who like light and heat. Especially in summer, there are more insects in the countryside.
Some insects like heat by nature. Incandescent lamps and energy-saving lamps will generate heat after using for a period of time. This heat is just what the insects like, so it is easy to attract insects. This will undoubtedly bring a lot of pollutants to the lamp surface, and the excretion of insects will make the room very dirty. However, LED light is a cold light source, will not attract insects to come over, so that there will not be insect excreta. So LED lights are more "clean.".
