The computer adjust and control the working current of LEDs by using three-color LEDs illumination acquired by CCD camera  achieved chromaticity coordinates error between compounded white light and standard white light D65 less than the threshold beforehand setted by this technique  then acquiring needed standard white light. Compounded white light meet the chromaticity error demand that is able to be changed  at the same time the CCD illumination acquisition system is eliminated. The proposed algorithm improved the light energy utilization efficiency of LED  and eliminated the offset of central wavelength and chromaticity coordinates due to work current change of LEDs. Experimental results show that the proposed algorithm achieved lesser chromaticity error uv=0.001 relative to standard white light D65  enhanced chromaticity uniformity of illumination field.   Study on chroma balance based on grating spectrometer for LED (EI CONFERENCE) 会议论文  OAI收割 Light-Emitting Diode Materials and Devices II, November 12, 2007 - November 14, 2007, Beijing, China 作者:  Meng Z.;  Meng Z. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 A standard white light compounding algorithm based on combination of choma coordinates acquisition system with computer working current control system is presented for three-color LED. The chroma coordinates acquisition system consist of grating spectrometer and integrating sphere. The computer adjust and control the working current of three-color LED  then achieved chroma coordinates error between the compounded white light and standard white light D65  until the chroma coordinates is less than the threshold beforehand set by this technique. The compounded white light meet the chroma error demanded that is able to be changed  at the same time the chroma coordinates acquisition system and the working current control system are eliminated. The proposed algorithm the offset of central wavelength and the change of chroma coordinates due to working current variety for LEDs. Experimental results show that the proposed algorithm achieved lesser chroma error uv=0.001 relative to standard white light D65  enhanced chroma uniformity of illumination field.   Synthesis and characterization of white-light-emitting polyfluorenes containing orange phosphorescent moieties in the side chain 期刊论文  OAI收割 JOURNAL OF POLYMER SCIENCE PART A-POLYMER CHEMISTRY, 2007, 卷号: 45, 期号: 9, 页码: 1746-1757 作者:  Mei, Chongyu;  Ding, Junqiao;  Yao, Bing;  Cheng, Yanxiang;  Xie, Zhiyuan   |  收藏  |  浏览/下载：24/0  |  提交时间：2019/04/09 Conjugated Polymers  Iridium Complexes  Light-emitting Diodes (Led)  Metal-polymer Complexes  Organic Electroluminescence  Polyfluorene  White-emissive Polymers   Indoor Visible Light Data Transmission System Utilizing White LED Lights 期刊论文  OAI收割 IEICE Transactions on Communications, 2003, 卷号: E86B, 期号: 8, 页码: 2440-2454 - 收藏  |  浏览/下载：18/0  |  提交时间：2016/05/16 optical wireless communication  white LED light  illuminance  luminous intensity  RMS delay spread  indoor visible light communication system   白光LED用荧光玻璃陶瓷的发光性能研究 学位论文  OAI收割 作者:  李杨   |  收藏  |  浏览/下载：27/0  |  提交时间：2018/12/26 荧光玻璃陶瓷  Color Conversion Glass Ceramic  白光LED  White Light-emitting Diode  量子效率  Quantum Yield  可靠性性能  Reliability Property  散热性能  Heat Dissipation Property
