Ambient lighting in surgical environments
An ambient lighting system for a hospital operating room environment and a method of using said system is described. An apparatus comprising the combination of a translucent sheet and a backlight LED panel or colored light source (colored lamp(s) or LED(s) in an alcove) provides a diffuse light when light from said panel, alcove, or other source is presented to the translucent sheet, is scattered, and represented as unfocused light on the exposed surface of the translucent sheet. Usage of the apparatus in an operating room provides a calming environment. The method and apparatus may be adapted to include wireless control over the intensity, color, and on/off state of the light. Further, usage of known translucent materials provides a sterile and safe surface.
1. 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.
2. The ambient lighting system of claim 1 , wherein said ambient light source is responsive to wireless control signals.
3. The ambient lighting system of claim 1 in which said translucent sheet is Avonite.
4. The ambient lighting system of claim 1 in which said light source is
(i) a focused, colored light,
(ii) an array of colored lights,
(iii) an array of colored, focused lights, or
(iv) an array of unfocused, colored lights.
5. The ambient lighting system of claim 1 in which said light source is an array of back-panels comprising at least one colored LED on at least one said back-panel.
