Conventional light sources are directly to consumers to buy, and LED module light source may also be in direct contact with the consumer in one day, which led to a higher module products require a lot. Finally, the product placement and product modules can be used to light the light source assembly direct consumer use, led module factory, but the optimal cost of the substrate, a light source module having a higher cost performance from people lighting requirements of view, LED module light source compared to SMD LED, led module purchase, at cost, reliability and assembly, etc. all have an absolute advantage. Thus, LED module light source in the future will be more general lighting applications shine. LED full color display is a new type of indoor and outdoor large-sized electronic media, with size, good environmental adaptability, high brightness, dynamic play and so on. With the further improvement of LED cost-effective, it can be widely used in advertising, stage, signs, traffic facilities, public places. LED as a new light-emitting device, led module manufacturers, with a proven energy-saving features. However, the large number of LED lamps component of LED full color display application has huge energy consumption; the same time, a large number of LED modules constitute LED display, Jiangsu led module, while the inner LED module is composed of a plurality of switching power supply, which kind of a lot of conventional switching power supply (without PFC correction) produce harmonic distortion can easily contaminate the public grid; therefore, electromagnetic compatibility and low power design LED display technology is an important direction of development. led module supply, Gao Jin Optoelectronics Technology (certified), Jiangsu led modules provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin. Jinan Gao Jin Optoelectronics Technology Co., Ltd.
