	New LED illumination optical engine for micro-projection display (EI CONFERENCE) 会议论文 OAI收割 5th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optoelectronic Materials and Devices for Detector, Imager, Display, and Energy Conversion Technology, April 26, 2010 - April 29, 2010, Dalian, China 作者: Meng Z.; Meng Z. 收藏 \| 浏览/下载：18/0 \| 提交时间：2013/03/25 A new optical engine consisting of LEDs rectangular CPC rectangular lens array and micro display chip DMD is designed by using of KOLA illumination algorithm for micro-projection display. Detail description and analysis of the rectangular CPC and rectangular lens array are provided. The influence due to the size of rectangular CPC and rectangular lens array is analysed for illuminance uniformity on the DMD chip and light energy efficiency of the optical engine system by software ZEMAX. Based on the analysis of parameter of rectangular lens array the size of rectangular lens array more decrease the illumination uniformity. Experimental results show that the proposed illumination light optical engine can obtain perfect rectangular focula with higher light uniformity more than 90 % and higher energy efficiency of 40 % to meet the needs of micro-projection display at the same time the designed illumination optical engine compared with other uniformizing light algorithm have advantages such as: lesser capacity high illumination uniformity. 2010 Copyright SPIE - The International Society for Optical Engineering.
	LED optical engine based on rectangular CPC for micro-projection display (EI CONFERENCE) 会议论文 OAI收割 4th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Advanced Optical Manufacturing Technologies, November 19, 2008 - November 21, 2008, Chengdu, China 作者: Meng Z.; Meng Z. 收藏 \| 浏览/下载：19/0 \| 提交时间：2013/03/25 With applications in digital display consumer electronics medicine automotive lighting traffic signals and general illumination the light-emitting diode (LED) is the world's most efficient light source being mass produced today[1]. However high cost is the main factor restricting widespread application of LED lighting and the packaging is the most expensive aspect of LED products. Light emitting diodes (LED) are regarded as the most important light sources in solid-state lighting for their advantages in energy efficiency long life vivid colors high reliability environmental protection safety and multiple applications. However application of LEDs in projection display exist many questions such as low illuminance uniformity and low energy efficiency by reason of luminescence distribution and constructure specificity for LED the study on application of LED in the micro-projection display and projection display is reported[2-8]. Considering the question mensioned above the rectangular CPC(Compound Parabolic Concentrator) system with three-color LED is applied in the projection display. 2009 SPIE.
	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：16/0 \| 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.
