LED new breakthrough is expected to change the indoor lighting environment

LED lamp features high efficiency and long service life, but because of color, easy to affect vision, not suitable for indoor lighting. The director of the Sun Qingcheng team of National Central University optoelectronic packaging technology, improve the LED light color problems, "" International Journal Optics Express published its research results.

National Central University school dean Li Zhengzhong said, high luminous efficiency, the advantages of long service life, low pollution with LED, is the future development trend; but because of the uneven distribution of color, the body can cause visual discomfort, it is mostly used in outdoor, should not be used in indoor lighting.

The school of Optoelectronic Science and engineering department director Sun Qingcheng said that indoor lighting should have appropriate brightness, light and comfortable, color space and time homogeneous; but now most of them have LED light color problem space, color space refers to the LED light generating intermediate blue, yellow around the "yellow halo", serious beam will form a high temperature at certain angles, adverse effects on the human body.

Sun Qingcheng pointed out that the research team to adjust the position and structure of the LED chip fluorescent powder, LED color packaging technology development leading the world, can reduce the color space of LED, more to break the world record of the best literature, also can make the LED lamp light into a white uniform, that can accelerate the LED used in the process of indoor lighting, has the application of the United States, China and Taiwan Chinese patent.
