Background

The light emitting diode, abbreviated As LED, is made of a compound containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), and the like. It is one of semiconductor diodes, and can convert electric energy into light energy; often abbreviated as LEDs. The light emitting diode is composed of a PN junction as common diodes, and also has unidirectional conductivity. When a forward voltage is applied to the light emitting diode, holes injected from the P region to the N region and electrons injected from the N region to the P region recombine with the electrons in the N region and the holes in the P region within a few micrometers near the PN junction, respectively, and spontaneous emission fluorescence is generated. The energy states of electrons and holes are different in different semiconductor materials. The more energy is released, the shorter the wavelength of light emitted, the more energy is released when electrons and holes recombine. The packaging of the LED semiconductor light emitting diode is a packaging of a light emitting chip, which is significantly different from the packaging of an integrated circuit, and the packaging of the LED is required to protect a wick and transmit light.
