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.
A surgical light apparatus having a light source and an enclosure surrounding the light source and including a reflector and a lens substantially transparent to visible light, the light source generating visible light and heat energy radiation, the apparatus comprising at least one filter element 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 at least one filter element being coupled to the enclosure and configured to block transmission of heat energy radiation from the light source to the reflector substantially over a 360° field of view about a longitudinal axis through the light source, the at least one filter element including a first end longitudinally spaced from a second end, and the at least one filter element being configured to define at least one gap located between the first and second ends.
An apparatus for cooling a surgical light fixture having a light source and an enclosure surrounding the light source, the enclosure including a reflector and a lens transparent to visible light, the reflector configured to reflect light from the light source towards the lens, the apparatus comprising a plurality of filter elements coupled to the enclosure between the light source and the reflector, the plurality of filter elements being formed at least in part from material that is substantially transparent to visible light radiation and that substantially blocks transmission of heat energy radiation, and the plurality of filter elements being configured to intersect substantially all radiation from the light source that otherwise would pass to the reflector and through the lens, the plurality of filter elements being configured to define at least one gap between two adjacent filter elements.
A surgical light apparatus comprising:
An apparatus for cooling a surgical light fixture having a light source and an enclosure surrounding the light source, the enclosure including a reflector and a lens transparent to visible light, the reflector configured to reflect light from the light source towards the lens, the apparatus comprising a filter coupled to the enclosure, the filter including means for blocking heat energy radiation emitted from the light source and means for permitting air flow between the reflector and the light source.
