ABSTRACT:
A luminaire especially adapted for use as an outdoor framing projector is weatherproof and has an optical system for projecting a beam of a variable size and focus. A housing made in extruded sections has a longitudinally continuous sealed joint between the sections formed by a dog-leg shaped lip on one adjacent section fitting into a correspondingly shaped recess on the other section, with a resilient sealing strip compressed between the lip and recess and a detent holding the lip and recess together. A fan forced interior air recirculation cooling system cools a lamp with the warmed air flowing longitudinally back to front past top and side walls of the housing provided with cooling fins and a return air duct adjacent to the bottom wall drawing air from the front of the housing back to the inlet of the fan. Daylight adjustment of the lamp relative to the reflector is allowed by providing the reflector with two holes which allow two reference beams to escape which are aligned with reference marks in the housing at the proper adjustment position. Lenses are supported from longitudinal flanges of the housing by bearing blocks which trap longitudinally running cylindrical bearings against the flanges and have clamp stands to secure the positions of the lenses.
