Use of high-power light emitting side case: dual front phone boxes, boxes community use cases, good lighting effects Jinan shutter light, uniform light effect, low energy consumption, light box size 1.2m * 1.5m, use two lights on both sides of the rally . Light-emitting diode (LED) is a kind of electrical energy into light can solid device, its structure is dominated by PN junction chip, electrodes and optical system. LED's basic working principle is an electro-optical conversion process Jiangsu shutter light, when a forward bias is applied to both ends of the PN junction, PN junction barrier due to the reduction of positive charge will be diffused N-P zone region, N region also to the P zone electron diffusion, accumulation of non-equilibrium charge simultaneously formed in the two regions. Since the current injection of minority carriers generated relatively unstable Zhengzhou shutter lamp, for PN junction system, is injected into the valence band holes to be unbalanced and conduction band electrons complex, which will be the excess energy in the form of light external radiation, the energy of electrons and holes the greater the difference, the higher photon energy to produce. Energy differential of different sizes, frequency and wavelength of the light generated is different, the color of the corresponding light will be different. Shutter lights, high beam illumination, Jiangsu shutter lamps provide lighting Technology Co., Ltd. from far. Shutter lights, high beam illumination, Jiangsu rolling light is far Lighting Technology Co.
