REFLECTOR AND SYSTEM
First Claim
Patent Images
1. An illumination system, comprising:
- a light source; and
a reflector, the reflector including;
a first optical interface adjacent the light source which redirects light emitted from the light source and incident on the first optical interface via Fresnel reflection; and
a second optical interface adjacent the first optical interface on a side opposite the light source, which reflects light passing through the first optical interface via total internal reflection back towards the first optical interface.

Abstract
An illumination system includes a light source and a reflector. The reflector includes a first optical interface adjacent the light source which redirects light emitted from the light source and incident on the first optical interface via Fresnel reflection. In addition, the reflector includes a second optical interface adjacent the first optical interface on a side opposite the light source, which reflects light passing through the first optical interface via total internal reflection back towards the first optical interface. Also, a light collection system includes such a reflector.
