What are the advantages of LEDs?

As a cold light source, LED has many advantages that traditional light sources cannot match. 1. It does not need to be inflated, does not need a glass shell, has good impact resistance, good shock resistance, is not easy to break, and is easy to transport.
2. The light source unit is smaller, which makes the lighting layout more flexible, and can better realize the effect of 'seeing the light but not the light source' in night scene lighting. 3. The composition of the luminescent spectrum can be better controlled, so it can be well used for partial or accent lighting in museums and exhibition halls. 4. In theory, it has a higher luminous efficiency than traditional light sources. In theory, the luminous efficiency of LED is greater than 200LM/W, so it has a huge energy-saving potential. 5. Longer life, the laboratory life can reach 100000h, and the light source can be turned on and off frequently without affecting its life, and the startup speed is very fast.
6. By controlling the size of the forbidden band of the semiconductor material in the semiconductor light-emitting layer, various colors of light can be emitted with higher chroma. 7. Mercury is not added to the light source, which is beneficial to protect the environment. 8. LED light has a strong directionality, which can better control the light and improve the lighting efficiency of the system. 9. Using low-voltage direct current, it has the advantages of small load and weak interference.
