MULTIPLE LIGHT SOURCE ILLUMINATION FOR IMAGE DISPLAY SYSTEMS

摘要

A method for transmitting light in an image display system includes generating a first cone of light (104) from a first light source (102). The first cone of light includes a plurality of light beams. A first portion (116) of the first cone is projected in an illumination path. A second portion (118) of the first cone is projected at a surface of a reflector (106). The second portion (118) of the first cone is reflected to project the second portion of the first cone in the illumination path. The first and second portions of the first cone are received at an entrance of an integrator rod (108). The second portion of the first cone increases the intensity of light received by the integrator rod.
