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.
