1. The
LED light is a semiconductor material chip with electrophoretic glowing. It is cured to the bracket with silver or white glue, and then connects the chip and circuit board with a silver line or gold wire. The role of the line, finally install the shell, so the LED light has good shock resistance.
2. LED (LightemittingDiode), light -emitting diode, is a semiconductor device that can convert electrical energy into visible light. It can directly convert electrical into light. The heart of LED is a semiconductor chip. One end of the chip is attached to a bracket, one end is the negative electrode, and the other end connects the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin.
3. The semiconductor chip consists of two parts, one is the P -type semiconductor. In it, the acupuncture points are dominated. The other end is N -type semiconductor, which is mainly electrons here. But when these two semiconductors are connected, a P -N knot is formed between them. When the current passs through the wire to act on this chip, the electrons will be pushed to the P area. In the P area, the electron and acupoints will be compounded, and then the energy will be emitted in the form of a photon. This is the principle of LED light light. The wavelength of light is the color of light, which is determined by the material that forms the P -N knot.
