Abstract
A light source reflector includes a structure having three or more internal reflective surfaces defining a first light entry aperture and a second light exit aperture having an area that is greater than the area of the entry aperture. A single light source, or a plurality of uniformly distributed light sources, such as one or more LEDs, located proximal the entry aperture provides illumination, which impinges on the reflective surfaces from the entry aperture and is reflected off the surfaces to provides a substantially uniform illumination pattern exiting the exit aperture. The reflector advantageously allows for the use of a source (e.g., LED(s)) that is smaller than the targeted area of illumination and also avoids creating hot-spots as the reflector does not focus the light, but rather reflects mirror images of the source off of the reflective surfaces.
