Abstract: A light assembly as used with street construction barricades is disclosed. In one embodiment, there is a base having a supporting platform with recesses in its upper surface, the recesses having a bottom, side walls and an open top. The recesses also have access holes in the bottom leading into the recesses from the exterior. A removable casing fits over the base to form a housing therewith. The casing has an interior cavity with side walls and a top extending above the recesses. A coupling connects the base to the casing upon substantially lateral movement of the base under the cavity. This restricts the vertical movement of the base relative to the casing. Batteries are insertable in the casing cavity so as to recede into the recesses upon assembly of the casing and base. The batteries will then block disassembly by limiting lateral movement of the casing relative to the base. A special tool is insertable in the access holes to push the batteries out of the recesses so as to allow disassembly.

Abstract: In a lighting fixture, a light source is partially surrounded by a reflector system mounted in a housing to direct light from the light source out through an aperture in the front of the housing. The reflector is cylindrically and parabolically shaped to provide a cut-off above a selected vertical angle and to provide a decreasing intensity with decreasing vertical angles from a maximum intensity to effect uniform distribution. A lens is provided in the aperture to achieve uniform distribution through a wide horizontal angle. The reflector system and the light source are pivotable within the housing about a fixed horizontal axis to adjust the vertical cut-off angle and the angle of the maximum intensity. A fixed reflector is mounted near the top of the aperture on the front wall of the housing to get more sideways distribution of the light when the light source is pivoted toward the back of the housing.

Abstract: A breakaway reuseable marker lamp suitable for airport runway usage utilizes a base which is threaded into existing electrical junction boxes along the runway and an upright post which is frictionally releaseably retained in a socket of the base for easy breakaway in response to impact by an aircraft or other vehicle and easily manually reinserted. The post includes inner and outer telescoping sections so as to vary the height of the post for changing local requirements. To avoid damage to wiring extending between base and post, the lower end of the post, which fits within the socket, has a beveled rim. Use of the rim helps prevent cutting or stripping of the electrical wiring which bears against the rim during separation of post and base.

Abstract: In a container comprising a plurality of panels held together by a support system having stiff collars at the corners of the panels and connecting members connecting together groups of said collars. At least some of the connecting members are elastic members, as a result of which the support system holds the panels together into a container of a desired polyhedral configuration under the tension of the elastic members.

Abstract: A luminaire for roadway lighting using a one-piece reflector developing at least two collimated beams in each longitudinal direction. The collimated beams impinge on sloping faces of a refractor to diverge the beams into a regular pattern covering the street with a sharp cutoff at predetermined longitudinal distances from the luminaire. The refractor employs a compressed parabola comprised of radial sections of comparatively large focal length with steps and risers. The complex shape of the one-piece reflector may readily be produced by a reflector finish applied to a molded plastic matrix. In the luminaire, the prismatic surfaces of the inclined walls of the refractor diverge the formerly collimated beams in a carefully controlled manner to produce very uniform distribution of light.
