Light emitting principle of diode LED lamp

- Oct 12, 2017 -

Since the LED lamps enter the lighting market, the traditional lighting methods such as incandescent lamp have suffered a great deal of shock, which stems from the advantages of LED lighting principle. Led home lighting factory for everyone introduced the light-emitting diode, led and other principles, from which we can see the traditional lighting by the impact of the reasons.

LED is a light emitting diode, LED is the heart of a semiconductor chip, the chip is attached to one end of a stent, one end is negative, the other end is connected with the power supply of the cathode, the entire chip package to be epoxy resin. Semiconductor wafers consist of two parts, one is P type semiconductor, in which the hole dominates, and the other end is N type semiconductor, which is mainly electronic here. But when the two semiconductors are connected, they form a P-N junction between them. When the current passes through the wire acting on the wafer, the electrons are pushed into the P region, where electrons combine with holes and then emit energy in the form of photons in the P region.

Under such circumstances, LED has the advantages of energy saving, environmental protection, safety, long service life, low power consumption, low heat, high brightness, waterproof, shockproof, easy adjustment, micro light beam focused, simple maintenance, can be widely applied in various directions, display, decoration, backlight, ordinary lighting etc..
