MULTI-COLOUR ILLUMINATION APPARATUS

摘要

A light engine is provided for a projection system, comprising a color wheel having a plurality of color phosphor portions; at least two light sources for illuminating the wheel at different locations for generating at least two time-sequenced beams of red, green and blue light, wherein the output beams are highly synchronized and exhibit substantially similar colorimetry, including spectrum and balance of red, green and blue light; and a digital micromirror device for modulating the time-sequenced beams of red, green and blue light to create an image. In another aspect, a light engine is provided for a tiled projection system having at least two projectors, comprising a color wheel having a plurality of color phosphor portions; a light source for generating a beam of light; a beam splitter for splitting the beam of light into at least two highly correlated beams to illuminate the wheel at different locations for generating at least two time-sequenced beams of identical red, green and blue light; and a digital micromirror device in each of the projectors for modulating the highly correlated beams to create a tiled image

1. A multi-color illumination apparatus for a projection system, comprising:
a phosphor color wheel having a plurality of color phosphor portions; at least two light sources for illuminating said wheel at different locations for generating at least two time-sequenced beams of red, green and blue light, wherein said beams are highly synchronized and exhibit substantially similar colorimetry, including spectrum and balance of red, green and blue light; and a spatial light modulator for modulating the time-sequenced beams of red, green and blue light to create an image.
