史高亮 led development of white light emitting diode (LED) technology continues to progress, bringing great potential solutions for energy-efficient lighting applications. High-brightness white LED popularity is the most important reason for its long life and luminous efficiency, when its brightness is maintained at 70%, life expectancy of up to 50,000 hours, outdoor area lighting can reach 12 years of operation time, large to drastically reduce the ongoing maintenance and replacement costs. Currently commercialized high power white LED, each lamp can reach 80-120 lumens of light output, efficiency of about 80 lm / W, and estimated in 2009 doubled in overall can reach 200 lumens per lamp luminous efficiency is expected to reach 160 lm / W. As a reference comparison, 100 W metal halide HID lamp can produce about 8, showcase lights, 000 lumen output, light output HID lamps are omnidirectional, Fuping showcase light bar professional production, so there will be light in the projected path of the large losses, but the LED is not the problem, Fuping showcase light bar manufacturers, because it has directivity, about 110 per package of 80 lm LED lamp to be able to replace 100 WHID lumen output, if the 2009 target is reached, this figure will be halved. LED light source of claim 1, the size of the chip size of the chip to side expressed great quality LED chip is better than small chips. Chip size is proportional to the price of the same. 2, LED colloidal colloid ordinary general epoxy resin, plus a UV LED and fire agents more expensive, high-quality outdoor LED lighting should be UV and fire. Fuping 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.
