Abstract: Improved lighting apparatus for illuminating roofs having characteristic disparate slopes. Such apparatus includes at least one housing secured along the top edge of such roof, preferably between adjacent pairs of decorative beams. The apparatus has an elongate light source therealong and a reflector to direct light toward two disparate-sloping roof sections for bright and even illumination. A shroud along the housing prevents glare beyond the lower edge of the roof. The housing is preferably movably mounted for easy servicing.

Abstract: The improved bollard luminaire has an upwardly directed, elliptical main reflector and a lamp "nested" within such reflector and positioned at or near its lower focal point. An upper cone-shaped reflector receives light from the main reflector and directs it laterally through a transparent lens element. Such element provides a 360.degree. lateral light opening unobstructed by wiring, support posts or the like. Light reflected through such opening is relatively sharply focused along an axis about 70.degree. from vertical. Unreflected light from the lamp which "misses" both reflectors also provides a degree of "uplighting," often found useful for aesthetic purposes.

Abstract: A floodlight having a housing with a lateral wall forming an access opening, an access door which when closed is recessed within the housing, and articulated hinges which extend between the interior surface of the lateral wall and the inside surface of the door.

Abstract: A lighting unit comprising a lamp and a reflector provides high intensity, high efficiency, even illumination over an area of particular shape and size and has a cut-off angle which enables a person to approach close to the lighting unit without seeing the lamp or its reflection. The reflector comprises at least two spaced apart curved reflector surfaces which join each other along an edge line in a plane behind and spaced from the lamp. Points on the curve line of each reflector surface are spaced progressively farther away from the lamp than the edge line. Some points on the curve are located on the side of the plane remote from the lamp. The lighting unit, which may employ reflector surfaces in addition to those above mentioned, may be employed in systems wherein it projects light upwardly for downward reflection from a ceiling or projects light downwardly directly onto a work surface.

Abstract: A light fixture for use in indirect lighting including a fixture assembly for supporting an elongated high intensity lamp in generally horizontally disposed relationship and including a reflector assembly for directing light from the lamp against an opposing surface in an evenly distributed pattern. The reflector assembly includes a pair of opposed side reflectors, opposed end reflectors adjacent the ends of the side reflectors, and diagonally disposed reflector panels which join the end reflectors to the side reflectors.

Abstract: An indirect lighting fixture for illuminating a desk top with light reflected from a room ceiling and for close association with the desk side comprises a hollow base extending beneath the desk, a pair of laterally spaced apart hollow support legs connected to the outermost side corners of the base and extending upwardly alongside the desk, and a lamp compartment connected to the upper ends of the legs and extending over the desk top in cantilever fashion above eye level. The lamp compartment which is open at the top but provided with a lens contains a metal halide or high pressure sodium lamp and a reflector for aiming the lamp light directly onto the ceiling for reflection directly down onto the desk top. The base contains relatively heavy electrical ballast components for starting and operating the lamp which also serve to weight the base and stabilize the fixture.
