Patent ID: 8002435

Claim:
An optical system for a LED fixture, comprising: a mounting surface; a plurality of individual LEDs attached to said mounting surface; a plurality of orientable lenses each having a base; a positioning sheet in contact with said base of each of said orientable lenses that provides force on said base of each of said orientable lenses in a direction towards said mounting surface, thereby compressing a portion of each of said orientable lenses between said mounting surface and said positioning sheet; wherein said base of each of said orientable lenses is adjacent to said mounting surface about a single LED of said plurality of LEDs; wherein said positioning sheet has a plurality of lens apertures, each of said lens apertures having at least one of an alignment protrusion and an alignment notch, each of said lens apertures surrounding one of said orientable lenses having a corresponding other of said alignment protrusion and said alignment notch, wherein said alignment protrusion and said alignment notch interface to position each of said orientable lenses at a predefined rotational angle; wherein each of said orientable lenses has a primary reflector at least partially surrounding a refracting lens; and wherein said refracting lens and said primary reflector of each of said orientable lenses collimate light emitted from said single LED to a reflective surface supported by said base of each of said orientable lenses and angled to reflect a majority of said light off a LED light output axis of said single LED.
