    LED lamp works

    Release date:2018-04-10

    The LED is a solid-state semiconductor device capable of converting electrical energy into visible light, a light-emitting diode that converts electricity directly into light. The heart of the LED is a semiconductor chip, one end of the chip attached to a bracket, one end is negative, the other end connected to the power of the positive, so that the entire chip is encapsulated by epoxy resin. Semiconductor chip consists of two parts, part of the P-type semiconductor, in which the dominant hole inside, the other end is the N-type semiconductor, mainly electronic here. When these two semiconductors are connected, they form a P-N junction. When the current through the wire acting on the chip, the electron will be pushed to the P area, in the P area with the hole in the electronic composite, and then will be issued in the form of photon energy, which is the principle of LED light. And the wavelength of light is the color of light, is formed by the formation of P-N knot material.


    A single LED lamp can only work at low voltage (about 3V), low current (about a few milliamps), the light is very weak. In order to make full use of alternating current positive and negative half-cycle current, which requires an integrated circuit chip, the AC 220V power supply into voltage, current can be used to achieve a single LED lamp beads in series or in parallel; And LED assembly to match the DC to meet the requirements of LED lamp beads assembly, so that it can be normal light.
