Title: Optical illumination system and projection display device
Inventor: OGAWA TAKANORI
IPC: H04N5/74
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To attain improvement in the utilization efficiency of light by reducing the incident angle of light flux into an illumination area without extending an optical path length by reducing the width of light flux emitted from an optical illumination system through a light flux reducing means having a converging function for providing an optical afocal system and a function for making light parallel. SOLUTION: This system is provided with a light source 20, a first lens array 30, a condenser lens 60, a divergent lens 70, a second lens array 40 and a superimposer lens 50. The condenser lens 60 and the divergent lens 70 arranged between the first and second lens arrays 30 and 40 consist of the optical afocal system for converting the incident light flux to emission light flux having the width of light flux narrower than the width of that light flux. Since the width of entire light flux is reduced by this optical afocal system, an incident angle θ1 is reduced. Therefore, in the case of using an optical element with an illumination area 80 as a light incident plane, the utilization efficiency of light, with which the illumination area 80 is effectively irradiated, can be improved.
