ABSTRACT:
A light collection system includes at least one light source, a light tunnel having reflective walls and a collimating plate at the light output end of the tunnel. The collimating plate includes an optical element array. The element array receives the light emitted from the light source and outputs part of the light at a desired cone angle and reflects the remainder back into the tunnel toward the light source. The light is “recycled” in the tunnel until the light either exits the collection system through the collimating plate or gets absorbed within the collection system.
