Korean-made light-emitting diode lamps will illuminate http://www.bgocled.com/ next year, as the Canadian city seeks street lights that are brighter and more durable, as well as energy-efficient, officials said Monday. Yuyang DNU, a Korean LED producer, will supply 20 units of 50-watt and 80-watt lights without charge to Vancouver and nearby Langley in southwestern Canada for a test operation, according to the Korea Trade-Investment Promotion Agency. The deal is to be signed Wednesday

Introduction of optical crystal power efficiency 170lm / W in warm white LED
With the rapid development of LED, LED luminous efficiency is always bigger and higher. Epistar R & D Center (Epistar Lab) has successfully developed a number of technologies, including a new generation of transparent substrate conversion process, increase the fine structure of the photon extraction efficiency can be improved with the current distribution uniformity, so that the red LED at a wavelength of 610 nm an efficiency of 174 lumens / watt. Meanwhile, in the high-voltage blue LED, as with the wavelength conversion material different from the traditional combination of formulas, verifiable good temperature of about 2800K warm white light efficiency of 170 lm / W, color rendering of 88. Today to achieve the above results, not only beyond the intended target, has continued to lead the industry. Epistar will continue to develop more advanced technologies to enhance product performance, together with downstream customers to extend the LED light source to the lighting market.
