ABSTRACT:
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.
