Abstract
A surgical light apparatus is disclosed having a first light source generating visible light and heat energy radiation, an enclosure surrounding the first light source and including a lens substantially transparent to visible light and a reflector for reflecting light from the first light source through the lens, and a filter apparatus coupled to the enclosure and formed at least in part from a material that is substantially transparent to at least a portion of visible light radiation and that substantially blocks transmission of heat energy radiation. The filter apparatus is configured to block transmission of heat energy radiation from the first light source to the reflector and to intercept substantially all radiation from the first light source that otherwise would pass to the reflector and through the lens. The filter apparatus includes a plurality of filter elements configured to define at least one gap between two adjacent filter elements allowing air flow therethrough.
