The use of LED lighting scale is an opportunity and a challenge for LED manufacturers?

Lumileds PHILPS Asia Marketing Director Mr. Zhou Xuejun, he believes that the prospect of LED is changing the entire industry. At present, LEDs has been used in outdoor lighting applications, shopping malls, hotels, and many other Home Furnishing, with the expansion of LED application and development, more and more lighting application requirements to achieve higher lower flux, more lm/W, LED products can cost more and faster return on investment period, the LED vendors will bring more opportunities and challenges. But in order to truly realize the use of LED lighting scale, LED manufacturers also need to light quality, performance and cost, reliability of three efforts.

He introduced elements of light quality is mainly reflected in the consistency, no significant difference and three color. Consistency requires that the product should be consistent with the quality of the light in the LED links, long-term use, and different environmental temperatures. At the same time, we should keep the color difference and good color rendering. In the LED performance improvement, but also need to use a variety of ways to further reduce product costs. Such as: to improve the LED epitaxial technology to increase the efficiency of light, the use of higher performance to improve the current, etc..

About LED reliability, he explained that the lumen maintenance rate, color stability, etc. are related to the reliability of supply chain. And the reliability of LED is not equal to the reliability of the whole LED system, because the whole LED system includes power supply, link, LEDs, optical design, heat dissipation and packaging technology, etc.. In order to specify in detail, he also cited the example of LUXEON RebEL.
