LED light system to improve the overall efficiency LED reliability, service life and reliability must be improved in order to optimize the system. Source: compact, efficient and choose the right color and output power. Control and drive: the use of electronic circuits LED constant current drive and control. Thermal management: To achieve a longer life must control the LED junction temperature, thermal model calculation using new technology and new materials, LED lamp technology is hot. Optical components: lenses, reflectors or light guide plate material is to focus light onto the target area or dispersed around, depending on the design needs. LED light source of claim 1, leakage current LED is one-way conductive light, if there is reverse current Yinchuan showcase light bar sales, is called leakage, leakage current is large LED showcase light bar, short life, low prices. 2, uses a different angle LED luminous light emitting angle is not the same. Special light-emitting angle, and higher prices. If all diffusion angle, and higher prices. 3, the key is the quality of life of different life, life is determined by the light fades. Light is small, long life, long life, high price. 4, chip LED luminous body for the chip, different chips, prices vary widely. Japan, the United States more expensive chips, generally made in Taiwan and chip prices lower than Japan, the United States. Yinchuan showcase light bar price, Shenzhen far illumination (certification), showcase light bar away from the Shenzhen Lighting Limited. Lighting Co., Ltd. Shenzhen far (www.zhenyuled.cn) (www.zhenyuanled.cn) is Xi'an, sodium leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . In Shenzhen far lighting leadership with the staff warmly welcome all inquiries negotiations to create lighting Shenzhen far better future.
