Abstract
A uniform illumination lighting module is disclosed herein. In some embodiments, the uniform illumination lighting module comprises a first optical medium, a lower reflective surface disposed adjacent to a bottom boundary of the first optical medium, a concave reflective surface disposed adjacent to a side boundary of the first optical medium, and a light source, wherein at least a portion of the first optical medium is disposed between the light source and the concave reflective surface. In some embodiments, the uniform illumination lighting module further comprises a second optical medium disposed adjacent to a top boundary of the first optical medium. In preferred embodiments, the concave reflective surface is substantially parabolic and the light source is disposed at a parabolic focus of the concave reflective surface.
