High-power LED as a light source with a small size, low power consumption, heat, long life, fast response, low voltage safety, weather resistance, good direction and so on. Housing available PC pipe production, high temperature of 135 degrees, low temperature -45 degrees 1 life: high power LED lamp life of up to 50,000 hours 2. Energy saving: saving more than 80% of the high-pressure sodium lamp 3 green . High-power LED lamps do not contain lead, mercury and other pollution elements, no environmental pollution 4. Security: impact resistance, earthquake and strong, led hair light in the visible range, ultraviolet (UV) and infrared (IR) radiation. No filament and glass case, there is no problem of fragmentation of the traditional lamp, the human body without harm, no radiation; light-emitting diode (LED) is a kind of electrical energy into light energy can solid state devices, its structure is dominated by the PN junction chip electrodes and optical system. LED is a basic principle of electro-optical conversion process, when a forward bias is applied to the PN junction ends of double-sided light boxes with lights, due to lower PN junction barrier, the positive charge will be diffused N P zone area, N electronics area to P area also spread the accumulation of non-equilibrium charge simultaneously formed in two regions. Due to the current injection of minority carriers generated in the production of relatively unstable double-sided light box for a PN system, injected into the valence band holes to be unbalanced and conduction band electrons in complex double-sided light boxes, in which the excess energy will outward form of light radiation, the energy difference between the electron and hole the greater the double-sided light box, the higher photon energy produced. Energy level difference of different sizes, frequency and wavelength of light generated is different, the color of the corresponding light will be different. Double-sided light box _ _ far sided light boxes lighting (certified merchants) provided by far Lighting Technology Co., Ltd. Far Lighting Technology Co., Ltd. (www.ygzmkj.com) is specialized in the "Rolling lights, light boxes, light bar, side-emitting light bar, power side-emitting light bar" of the enterprise, the company of "honesty, hard service "concept, to provide you with the highest quality products and services.
