Patent ID: 7841737

Claim:
An ambient lighting system for a hospital operating room, comprising: at least one ambient light source, each ambient light source comprising: (i) a non-porous translucent sheet with a low dielectric constant, wherein the translucent sheet comprises: a first surface, the first surface positioned proximal to and exposed to the hospital operating room; an interior; and a second surface substantially parallel to the first surface, the second surface positioned distal to and not exposed to the hospital operating room; (ii) a reflector, wherein the reflector is positioned further distal to the hospital operating room than the translucent sheet and in optical juxtaposition to the translucent sheet; and (iii) a light source, which is optionally colored, wherein the light source is positioned so as to be capable of directly illuminating the non-exposed surface of the translucent sheet and indirectly illuminating the non-exposed surface of the translucent sheet by reflection off the reflector; wherein the interior and the exposed surface of the translucent sheet provide a diffuse ambient light to the hospital operating room when the lighting source directly and indirectly illuminates the non-exposed surface, and wherein said ambient lighting system is disposed on a majority of walls of a hospital operating room.
