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