Why can't the LED bulb break?

Date: 2018-12-27
LED bulb is an electroluminescent semiconductor chip. It is solidified on the bracket with silver glue or white glue, and then connected with the chip and circuit board with silver or gold wire. It is sealed with epoxy resin around it, which protects the inner core wire. Finally, the shell is installed, so the anti-seismic performance of the LED lamp is good.
 
 
 
LED light emitting diode (LED) is a kind of solid-state semiconductor device which can convert electric energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor wafer. One end of the wafer is attached to a bracket, the other end is connected with the positive pole of the power supply, so that the whole wafer is encapsulated by epoxy resin.
 
 
 
Semiconductor wafers consist of two parts, one is P-type semiconductor, in which holes dominate, and the other is N-type semiconductor, in which electrons dominate. But when the two semiconductors are connected, a P-N junction is formed between them. When the current acts on the chip through the wire, the electrons are pushed to the P region, where the electrons recombine with the holes and then emit energy in the form of photons, which is the principle of LED lamp luminescence. The wavelength of light, the color of light, is determined by the material that forms the P-N junction.
 
 
 
LED can directly emit red, yellow, blue, green, green, orange, purple, white light.
