发明名称 Metal halide accent fixture with adjustable reflector/beam spread
摘要 A metal halide light fixture includes three generally cylindrical parts including a lamp housing with a lamp and a lamp socket, an intermediate sleeve member secured to the lamp housing, and a third focusing housing secured to the intermediate sleeve member. The focusing housing includes a reflector member including a concave reflecting surface and a lens. The lamp housing carries a T-6 lamp or similar lamp which includes a cylindrical arc tube having a significant axial length. Rotating the focusing housing moves the reflector member which surrounds the lamp axially relative to the arc tube to shift the light output pattern from floodlight to spotlight. The lamp housing is connected to a mounting structure through a swivel connection. Wires from the lamp socket are fed through a port in the lamp housing and a channel in the mounting structure and are potted in place. Threaded connections between the three principal parts are protected by O-ring seals.
