Information

LED, LED, is a solid state semiconductor device that converts electricity directly into Light. The heart of the LED is a semiconductor chip with one end attached to a scaffold, one end attached to a negative pole, and the other connected to the positive pole of the power supply, so that the whole chip is encapsulated in epoxy resin. A semiconductor chip consists of two parts: a P-type semiconductor, in which holes dominate, and an N-type semiconductor, in which electrons dominate. But when the two semiconductors are connected, they form a "P-N junction" between them. When an electric current is applied to the chip through the wire, the electrons are pushed into the P-zone, where they combine with the hole and emit energy in the form of photons, which is how leds light up. And the wavelength of light determines the color of light, which is determined by the material that forms the P-N junction. As shown in the figure, LED is composed of LED bracket, chip, lens, etc. LED bracket is an important part of LED.
