1. LED energy-saving lamps are a new generation of lighting sources after compact fluorescent lamps (ordinary energy-saving lamps). LED energy-saving lamps are environmentally friendly, mercury-free, recyclable, low power, high luminous efficiency, and long-lasting. Long life, bright as soon as it is turned on, resistant to frequent switching, small light decay, rich colors, dimmable, and rich in changes.
2. In the 1960s, people already understood the basic knowledge that semiconductor materials can produce light. The first commercial diode was produced in 1960. LED is the abbreviation of English lightemitting diode. Its basic structure is a piece of electroluminescent semiconductor material, placed on a leaded shelf, and then sealed with epoxy resin around to protect the internal core wire. Therefore, LED has good earthquake resistance.
