The Principle Of The LED Led Light

Sep 04, 2018

Since the LED lamps entered the lighting market, traditional lighting methods such as incandescent lamps have suffered a great impact, which is due to the advantages brought by the led lighting principle. Led home lighting factory introduced the principle of LED led light, etc., from which we can see the reasons for the impact of traditional lighting.

    LED is a light-emitting diode. The heart of LED is a semiconductor wafer. One end of the chip is attached to a bracket. One end is a negative pole and the other end is connected to the positive pole of the power supply, so that the entire wafer is encapsulated by epoxy resin. The semiconductor wafer consists of two parts, one part is a P-type semiconductor, in which the hole dominates, and the other end is an N-type semiconductor, which is mainly electrons here. But when the two semiconductors are connected, they form a P-N junction. When a current is applied to the wafer through the wire, the electrons are pushed toward the P region where the electrons recombine with the holes and then emit energy in the form of photons.

    Under such circumstances, LED has the characteristics of energy saving, environmental protection, safety, long life, low power consumption, low heat, high brightness, waterproof, miniature, shockproof, easy dimming, concentrated beam, easy maintenance, etc., and can be widely used in various indications. , display, decoration, backlight, general lighting and other fields.
