Background

An LED, i.e., a light emitting diode, is a solid-state semiconductor device capable of converting electrical energy into visible light, which can directly convert electricity into light. The heart of the LED is a semiconductor wafer, one end of the wafer is attached to a support, the other end of the wafer is a cathode, and the other end of the wafer is connected with an anode of a power supply, so that the whole wafer is packaged by epoxy resin. The semiconductor wafer is composed of two parts, one of which is a P-type semiconductor in which holes predominate and the other of which is an N-type semiconductor in which electrons predominate. When the two semiconductors are connected, a P-N junction is formed between them. When current is applied to the wafer through the wire, electrons are pushed to the P region where they recombine with holes and then emit energy in the form of photons, which is the principle of LED lamp illumination.
