	Study on chromaticity balance for LED exposure system (EI CONFERENCE) 会议论文 OAI收割 International Symposium on Photoelectronic Detection and Imaging 2007 - Laser, Ultraviolet, and Terahertz Technology, September 9, 2007 - September 12, 2007, Beijing, China 作者: Meng Z.; Meng Z. 收藏 \| 浏览/下载：17/0 \| 提交时间：2013/03/25 A standard white light compounding algorithm based on combination of CCD illumination acquisition with computer control is presented for LEDs. 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.
