Abstract
Disclosed herein is an improved dental operatory lamp having an LED light source that directs light to a reflector that in turn reflects the light to illuminate a treatment area. In one embodiment, the lamp is adapted for efficient transfer of heat from the light source and into the environment. In another embodiment, the lamp is adapted to generate a predetermined pattern of light optimal for the treatment area. In other embodiments, the lamp includes structural features that enable the lamp to maintain optimum light intensity and/or temperature. Also, disclosed herein are unique reflector embodiments that intentionally provide a generally smooth surface, without facets, that reflect light at all visible and infrared wavelengths.
