Luminescence principle

LED (Light Emitting Diode), light emitting diode, is a solid-state semiconductor device that converts electrical energy directly into light energy. The heart of the LED is a semiconductor chip, one end of the chip is attached to a bracket, is the negative electrode, the other end is connected to the positive electrode of the power supply, the entire chip is encapsulated by epoxy resin. A semiconductor chip consists of two parts, one is a P-type semiconductor, in which holes dominate, and the other is an N-type semiconductor, on which are mainly electrons. But when the two semiconductors are connected, a "P-N junction" is formed between them. When the current is applied to the chip through the wire, the electrons are pushed to the P region, where the electrons are combined with the holes, and then the energy is emitted in the form of photons, which is the principle of LED light. The wavelength of light determines the color of light, which is determined by the material forming the P-N junction.
