Abstract
In some embodiments, optical systems with a reflector and a lens proximate a light output opening of the reflector provide light output with high spatial uniformity and high efficiency. The reflectors are shaped to provide substantially angularly uniform light output and the lens is configured to transform this angularly uniform light output into spatially uniform light output. The light output may be directed into a light modulator, which modulates the light to project an image.
Claims30
An optical system comprising:
- a reflector comprising:
- a light input opening;
- a light output opening;
- and
- reflective interior sidewalls extending between the light input opening and the light output opening, and
- a lens proximate a light output opening of the reflector.
The optical system of claim 18, wherein a CPC curvature of two opposing interior sidewalls is different from a CPC curvature of others of the interior sidewalls.
