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.

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.
