Led lights features high efficiency, long service life, but because the color slants, easy to affect vision, not suitable for indoor lighting. While there are now advanced led testing instrument < http://www.semilamp.com > can detect their light color, but still can't do is perfect.
Taiwan's central university of photoelectric SunQingCheng groups using packaging technology, improve the color shift LED lights, international journal optical express "published the results of their study.
Taiwan's central university of neo-confucianism in the middle of the lee said, LED with high luminous efficiency, long life and low pollution advantages, is the trend of the development of the future; But because the colour maldistribution, can cause human body visual uncomfortable, so most used in outdoor, unfavorable use in indoor lighting.
The school of science and engineering SunQingCheng photoelectric, says that indoor illume should have appropriate brightness, comfortable light field, and space and time are all color sex; But now most of LED lights JianSe partial free, space is light color shift to produce LED among around slant blue, yellow "HuangYun", serious will at some point high beams of light color temperature formation, causes undesirable effect to human body.
SunQingCheng points out, the team adjust led chips position and phosphor structure, development first global led light color encapsulation technology can reduce led space color slants, more break of the literature best world record, also can let the led lights light into uniform white light, believe that can accelerate led used in indoor lighting of schedule, at present has applied for the United States, Taiwan and mainland China patent.
The technology is the most may change the indoor lighting, let the led lighting a better use of the technology.
