LDE light-emitting principle of LED (Light Emitting Diode), light emitting diode, is a solid state semiconductor devices, which can be converted directly into electricity to light. LED heart is a semiconductor chip, Huxian showcase light bar direct wafer mounted on a bracket, one end is negative, the positive electrode and the other end connected to the power supply, so that the whole chip is epoxy encapsulated. Semiconductor chip consists of two parts, part of P-type semiconductor, the hole in it dominates the other side is N-type semiconductor, here is mainly electronic. But when the two semiconductor connected to form a PN junction between them. When the current through the wire act on the chip, the electron will be pushed to P zone electron hole recombination, and then will be issued in the form of photon energy in the P area, this is the principle of LED light. The wavelength of light that is the color of light, showcase lights, PN junction is formed by the material of the decision. Prospects LED LED lamps, Huxian showcase light bar professional, can choose different colors of LED light combined into a soft illumination of various modules, any installation led lighting in the living room, bedroom lighting sources may come from the ground, the wall , bay windows, furniture, accessories and so on. Therefore, the future will no longer be confined to a single room lighting fixtures, and will be converted to a single lighting No Lighting sense of overall shadowless lighting effects. Different light color and brightness of human physiology and psychology can have different effects, people in many cases do not need a very bright white, yellow or other colors may be more suitable for light physical and psychological needs. Three-color LED can achieve brightness, grayscale, color and choice of continuous transformation, so that the lighting scale from white common sense for a variety of colors of light Huxian showcase light bar light bar Showcase price _ _ Chun Chun far away illuminated by lighting Limited. Lighting Co., Ltd. Shenzhen far (www.zhenyuled.cn) (www.zhenyuanled.cn) strong, credible, in Xi'an of sodium and other industries has accumulated a large number of loyal customers.
