LIGHT BOXES WITH UNIFORM LIGHT DISTRIBUTION
First Claim
1. 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 space adjacent the inner surface of the translucent panel;
a light source positioned within the light box; and
an optical lens operatively associated with the light source, such that light emitted from the light source is uniformly distributed throughout the diffusion space and across the translucent panel.

Abstract
Light boxes for uniformly illuminating panels include a frame that supports one or more translucent panels. The light boxes further include a light source positioned within the light box. Example light sources can include fluorescent bulbs, incandescent lights, and/or light-emitting-diodes. In at least one implementation, a manufacturer positions a relatively limited number of light sources aimed and/or positioned in a particular way to uniformly distribute light throughout the light box and evenly across the translucent panels such that there are no shadows, hot spots or other non-uniform light patterns on the translucent panels.

18. An illuminated piece of furniture wherein the illuminated portion of the furniture has a uniform light distribution, comprising:
a light box that forms a substantially hollow region surrounded by one or more translucent panels, the light box comprising; a light fixture having a light source positioned such that light emitted by the light source is directed towards the one or more translucent panels; an optical element associated with the light source such that the light emitted by the light source is directed through the optical element and diffused at a predetermined beam angle. - View Dependent Claims (19, 20)
