基于高显色指数白光LED的混色研究
Health Lighting Research Based on Mixing White LEDs of High Color Rendering Index
摘要
Abstract
The color temperature ( TC ) , color rendering index ( Ra ) and blue light hazard ( LB ) were analyzed by experiments and theories after mixing low color temperature and high color index white LEDs with different color temperatures. We have further researched the change of blue light hazard ( LB ) under the condition of different current. We adopt the method of mixing three different low color temperature (2 200 K, 2 700 K, 4 000 K) white LEDs, in the same time, we observed and recorded the change of the color rendering index and the lighting effect. Than we could calculate the changes of blue light hazard (LB) through writing a MATLAB program. The results of experiment and simulation show that, we can obtain the high quality white LEDs of high color Rendering Index ( Ra12、13、23 > 95 ) and low-blue light hazard. It also can meet the demand of healthy lighting.关键词
