LED lamps are light-emitting diodes, which use solid semiconductor chips as luminescent materials. Compared with traditional lamps, LED lamps are energy-saving, environmentally friendly, and have good color rendering and response speed.

(1) Energy saving is the most prominent feature of LED lamps. 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. Nowadays, people advocate energy saving and environmental protection. It is precisely because of this feature of energy saving that LED lights are widely used, making LED lights very popular.

(2) It can work in high-speed switching state. We usually walk on the road, and we will find that the screen or picture composed of each LED is unpredictable. This shows that the LED light can perform high-speed switching work. However, for the incandescent lamps we usually use, such a working state cannot be achieved. In daily life, if the number of switches is too many, it will directly cause the filament of the incandescent lamp to break. This is also an important reason for the popularity of LED lights. [3] (3) Environmentally friendly LED lamps do not contain any heavy metal materials such as mercury, but are contained in fluorescent lamps, which reflects the environmental protection characteristics of LED lamps. Nowadays, people attach great importance to environmental protection, so more people are willing to choose environmentally friendly LED lights.

(4) Fast response speed Another prominent feature of LED lights is that the response speed is relatively fast. As soon as the power is turned on, the LED light will light up immediately. Compared with the energy-saving lamps we usually use, the reaction speed is faster. When turning on the traditional light bulbs, it often takes a long time to illuminate the room, and it can only light up after the light bulbs are completely heated.

(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 that the lamp is a cold light source and does not generate too much heat. Attracts light and heat-loving insects. Especially in summer, there are many bugs in rural areas. Some bugs are naturally fond of heat. Incandescent lamps and energy-saving lamps will generate heat after a period of use. This heat is exactly what bugs like, and it is easy to attract bugs. This will undoubtedly bring a lot of pollutants to the surface of the lamp, and the excrement of insects will also make the room very dirty. However, the LED light is a cold light source and will not attract bugs, so there will be no bug excrement. Therefore, LED lights are more "clean".
