Claim:
A uniformly illuminated light box that substantially eliminates hot spots, shadows, scalloping or other non-uniform light characteristics from the lighted panels, comprising: a frame; a translucent panel coupled to the frame, the translucent panel having an inner surface and an outer surface; a diffusion cavity adjacent the inner surface of the translucent panel; a plurality of light sources positioned within the light box; and a plurality of optical lenses, each optical lens of the plurality of optical lenses being operatively associated with an individual light source of the plurality of light sources, the plurality of optical lenses comprising optical lenses with at least two differing beam angles, the plurality of light sources and the plurality of optical lenses being arranged in the light box such that the optical lenses alternate between the at least two differing beam angles such that light emitted from the plurality of light sources is uniformly distributed throughout the diffusion cavity and across the translucent panel.
