| Patent Number: |
7210806 |
| Title: |
High-Density Illumination System |
| Abstract: |
A compact and efficient optical illumination system featuring planar
multi-layered LED light source arrays concentrating their polarized or
un-polarized output within a limited angular range. The optical system
manipulates light emitted by a planar array of
electrically-interconnected LED chips positioned within the input
apertures of a corresponding array of shaped metallic reflecting bins
using at least one of elevated prismatic films, polarization converting
films, micro-lens arrays and external hemispherical or ellipsoidal
reflecting elements. Practical applications of the LED array illumination
systems include compact LCD or DMD video image projectors, as well as
general lighting, automotive lighting, and LCD backlighting.
