Do you know what LED lights are?
- Sep 26, 2018 -

LED, a light-emitting diode, is a solid-state semiconductor device that converts electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor wafer, one end of which is attached to a bracket, the other end is connected to the positive pole of the power supply, so that the entire wafer is encapsulated by epoxy resin.

It uses solid-state semiconductor chips as luminescent materials, which emit excess energy by recombination of carriers in semiconductors, and directly emits red, yellow, blue, green, blue, orange, purple and white light. LED lighting products are lighting appliances made from LED.
