The system includes a blower having a forced air outlet with first a conduit connectings the outlet of the blower to an inlet of the light tube. A second conduit connects to an outlet of the light tube to form a circulating air path through which air is forced by the blower to ventilate the light tube. Preferably, the light tube comprises an elongate base member and an elongate light diffuser for supporting the lamps along the light tube. The light tube also includes an elongate track member having a tongue along its entire length which mates which a groove along the length of the base member to secure the track in the base member. Each of the individual lamps is supported in the elongate track member by an adapter track clip which is press-fitted, rather than twisted, into the track.

Abstract: The present invention provides a brightness equalizing light filter system which can be utilized as the bottom panel or as one of a set of bottom panels in an indirect fluorescent light fixture to evenly illuminate the fixture to approximately the same degree of brightness as the surrounding area which it lights. The brightness equalizing light filter system comprises a translucent diffuser panel with an opaque, electrically-connected pattern of thin metal film deposited thereon, wherein the density of the opaque pattern for each point on the panel is proportional to (or the linear function of) the intensity of light impinging on that point from the light source. The metal film serves both as the required electrical ground to act as a starting aid for the lamps and as a reflecting surface to increase the photometric efficiency of the fixture.

Abstract: A lighting fixture adapted for uniformly illuminating a wall surface by utilizing an asymmetric light reflection pattern. The fixture includes a support housing and an elongated concave-shaped reflector which is pivotably attached to the support housing and has multiple facet surfaces arranged for reflecting light from the centrally located light source out through a front opening, which is covered with an ultraviolet filtering glass diffusion plate. The reflector has major rear and minor front reflecting portions, each portion containing multiple facet surfaces arranged in upper and lower zones with varying angles measured relative to a central vertical plane selected for reflecting light from the light source uniformly out through the diffusion plate to provide an asymmetric lighting pattern for uniformly illuminating a wall surface.

Abstract: A stackable louver assembly for light fixtures which can be made of a high strength polycarbonate light transmitting plastic material and which has a sleeve and louver flange molded in one piece so that the sleeve will not be lost or discarded at the job site. The louver assembly becomes self-enclosed. The louver assemblies are made so they can be stacked one on top of the other and fastened with tie rods at desired locations. The sleeve that supports the louver flange is made with a surface that is generally parallel to the longitudinal axis of the assembly, and can be provided with v-type grooves to provide refraction of the light emanating from an interior lamp. The grooves can be molded into the plastic with no increase in cost, and will reduce glare and improve overall performance of the fixture. Likewise, the louver flanges may have surfaces that are provided with refraction grooves, as well.

Abstract: A banner support arm safety coupling rigidly mounts banner support arms to a pole and has a frangible or breakable portion so the coupling will break under loads on the banner before the pole fails. A safety line holds the coupling portion from completely separating after the frangible portion breaks.

Abstract: A sleeve type lamp stabilizer that is made so that it will fit over a lamp socket, to be rigidly held in place with respect to the socket. The stabilizer can be clamped to the socket or rigidly connected to the lamp housing which mounts the socket. The sleeve type stabilizer has pads that support the lamp at the lamp neck. The need for support results from the common practice to provide a small amount of clearance between the lamp socket and the mating base of the lamp to insure that the lamp will not corrode in place or otherwise become stuck in its socket when it is time to replace the lamp with present large lamps. This slight amount of play in the socket translates into a large amount of movement at the opposite end of the lamp and thus the independent support stabilizes the lamp, and prevents mechanical vibrations from prematurely causing lamp failure.

Abstract: A battery operated lamp and battery charger are disclosed. The lamp is equipped with a rechargeable battery and a battery charger stand. The lamp has a lamp support surface with a center terminal, and a second terminal spaced from the center which engages the center terminal and second terminal respectively on the lamp. Thus the two lamp terminals will engage the two respective charge terminals regardless of the position of orientation in which the lamp is placed on the charger. The charger circuit is powered from a power cord connected to a power line through a transformer a full wave rectifier to charging lines. These diodes and a switch are connected in parallel with two diodes. The lamp battery to be charged is connected in parallel with the charging lines. Thus, with the switch closed, the charging voltage is reduced to desired value by a voltage drop caused by the resistor and the three diodes in parallel with the battery.

Abstract: A lamp stabilizer adapted to be mounted to the housing of a light fixture includes a mounting bracket secured to the light fixture and an elongated rigid rod slidably mounted for axial movement with respect to the bracket. The lamp stabilizer has a lamp engaging socket mounted on one end of the rod for selective engagement with an outer end portion of a lamp mounted in the housing. The lamp engaging socket is generally frustum-shaped and has at least one layer of heat insulating and lamp cushioning material secured to an inner side thereof for direct engagement with the outer end portion of the lamp. The lamp engaging socket is positioned with respect to the lamp by moving the rod with respect to the mounting bracket. A friction clip is selectively securable along the axial length of the rod and when secured thereto, engages the mounting bracket to restrict movement of the rod in direction away from the lamp.
