1, LED is the abbreviation of English light emitting diode. Its basic structure is an electroluminescent semiconductor chip, which is solidified on the bracket with silver glue or white glue, then the chip and the circuit board are connected with silver wire or gold wire, and then the periphery is sealed with epoxy resin to protect the internal core wire. Finally, the shell is installed to make the led lamps have good seismic performance.
2.LED (Light Emitting Diode) is a solid semiconductor device that can convert electric energy into visible light, and it can directly convert electricity into light. The heart of LED is a semiconductor chip, one end of which is attached to the bracket, one end is the negative electrode, and the other end is connected to the positive electrode of power supply, so that the whole chip is encapsulated by epoxy resin. The semiconductor wafer consists of two parts, one is a P-type semiconductor, in which holes are dominant, and the other is an N-type semiconductor, mainly electrons.
