基于LED光源的DLP光学引擎的光学设计
Optical Design of DLP Optical Engine Based on LED Light Source
摘要
Abstract
A new DLP Optical Engine based on LED Light Source in the illuminating system for rear projection television(RPTV)is proposed.The prototype employs HD2+Digital Micromirror Device(DMD)as the image chip,and the Fly-Lens as the homogeneous elements.The principle of the optical design method based on etendue is analyzed to design the system structure.The Fly-Lens illumination system has been employed tO realize high light collection efficiency and the optical uniformities and the optical component design is discussed.The simulation result is also proposed.Finally,the prototype is manufactured and the test result is compared to the simulation result.The white field output flux is 112.3 lm,and the homochromatic output flux R-26.1 lm,G-51.4 lm and B-19.0 lm is achieved with timing sequence distribution for the three groups of LEDs R:G:B(10:15:11).The uniformities are below±20%.关键词
