Abstract:
1. A lighting fixture comprising: a housing having an opening and containing a fan and at least one heat-generating light bulb to produce light at the opening; a protective lens assembly positioned below the housing opening, the protective lens assembly including a top clear or translucent solid lens and a bottom clear or translucent lens having a central opening for passing air into the protective lens assembly, the bottom lens being spaced from the top lens to provide a first ventilation gap between the lenses while protecting the interior of the housing; and a transparent refractor having proximal and distal openings positioned with its proximal opening at the housing opening, the protective lens assembly being positioned with the bottom lens of the assembly at the distal opening of the refractor and the outer edge of the top lens spaced from the border of the distal opening of the refractor to form the second ventilation gap, whereby the fan may be operated to cool the light bulb by moving air through the central opening in the bottom lens to the first and second ventilation gaps and across the bulb.
