ABSTRACT:
The present invention provides an optical device configured for the creation of an asymmetric illumination beam pattern while additionally mixing the light created by two or more light-emitting elements. The optical device comprises a reflector body which extends between an entrance aperture and an exit aperture, wherein the two or more light emitting elements are positioned relative to the entrance aperture and light is reflected within the reflector body exiting at the exit aperture. The reflector body includes a first pair of walls including symmetric reflective elements and a second pair of walls orthogonal to the first pair of walls, wherein the second pair of walls includes asymmetric reflective elements. The first pair of walls provides a means for mixing the light generated by the two of more light-emitting elements and generating a symmetric beam pattern about a first axis. Along a second axis, orthogonal to the first axis, the second pair of walls provides a means for mixing the light generated by the two or more light-emitting elements and generating an asymmetric beam pattern.
