Title: Research and realization of innovative LED illumination system for DLP projector
Abstract: With the development of DLP projection technology, DLP is gradually occupying LCD projector market. To the limitations and faults of mechanical color wheel in conventional DLP projection system, we study illumination structure based on high-power LED system. An innovative method is proposed. Through establishing test platforms, parameters of illumination system and constant current modules for high-Power LED are obtained. The results indicate that this method simplifies the structure of digital constant current source, reduces costs of system and improves accuracy. In the application of DLP stereo prototype projector, the proposed method meets the demands of high efficiency, rich color, long lifetime etc. Thus, more colorful and vivid image is showed, three-dimensional video performed by our innovative projector will become more fluent in the near future.
