Abstract
A light having a shielded fixture housing which comprises a tapered reflector a halogen lamp at the narrowed end, a tempered glass shield at the light-emitting end at a selected distance from the halogen bulb, and vents disposed about the fixture to provide an airflow therethrough. Embodiments according to the present invention pass the Underwriters Laboratory “Cheesecloth Test” and provide a light with significantly reduced fire hazard. Further improvements include specifically disposed temperature sensors to interrupt the power to the lamp if the light is accidentally or intentionally misused.
Claims11
A light fixture for a high temperature light bulb, comprising:
- a chimney having substantially vertically oriented side member forming a closed channel and open first and second end, a generally planar member disposed at said channel first end and having openings therein to allow airflow to enter and flow therethrough and being connected to said side member;
- a tapered reflector having a first opening adapted to receive said channel second end and having a cross section expanding as distance from said chimney increases and terminating in a second end;
- a light bulb support receiving said high temperature light bulb and being disposed between said channel first end and said tapered reflector second end, said light bulb support providing clearance to said tapered reflector and said channel to permit airflow therethrough from said channel;
- and
- a solid transparent shield disposed at said second end of said tapered reflector mounted at a distance from said high temperature light bulb sufficient to provide a surface temperature of the surface distal from said high temperature light bulb below a selected temperature and further having a surface area less than the area of said tapered reflector second end to provide at least one opening for said airflow from said chimney to exit said tapered reflector second end.
A light fixture for a high temperature light bulb, comprising:
- a tapered reflector having an opening at a first end having a cross section expanding as distance from said first end increases toward a second end, wherein
- said second end comprises at least one opening therein to permit exiting airflow therethrough and wherein
- said tapered reflector further includes at least one aperture substantially at said first end of said tapered reflector;
- a light bulb support receiving said high temperature light bulb and being disposed in said tapered reflector between said first end and said second end, said light bulb support providing clearance to said tapered reflector to permit airflow therethrough;
- and
- a solid transparent shield disposed at said second end of said tapered reflector mounted at a distance from said high temperature light bulb sufficient to provide a surface temperature of the surface distal from said high temperature light bulb below a selected temperature.
