Abstract: A luminaire motorized shade or douser mechanism includes a lamp mounted within a reflector and a motorized shade unit that opens and closes in front of the lens of the reflector. The shade unit includes a motor, two rollers, two guide cables, a sheet of opaque flexible material or fabric, and an aluminum frame. The motor drives the roller to run the shade in front of the lens to cover it and also to uncover. The motorized shade or douser mechanism is used to effectively block the light emitting from the lamp and create a condition whereas no light leaves the lens of the luminaire.

Abstract: A light fixture includes a lamp mounted within a reflector. The reflector includes a first surface lying in a generally parabolic sheet and being bounded in the generally parabolic sheet by first and second edges. A pair of generally opposing surfaces are connected to the first surface at the first and second edges. The generally opposing surfaces have a shape such that the lamp provides a generally rectangular beam pattern when the reflector reflects or redirects light from the lamp.

Abstract: A touch sensitive switching apparatus for controlling the operation of an electrical load is disclosed. The apparatus includes a programmable controller and a touch sensor assembly. The controller is connected to the electrical load and is programmable to provide a repeatable sequence to operate the load wherein each step of the sequence is initiated by touching two contact surfaces of the touch sensor assembly. The controller can also be configured to duplicate a momentary switch wherein the load is energized as long as the contact surfaces of the touch sensor assembly are connected. The touch sensor assembly can be mounted in a wall panel. The assembly includes a conductive housing with a conductive rod positioned therein. A first fastener secures the rod within the housing, while a second fastener secures the assembly to the wall panel.

Abstract: A holder includes a support member and a reflector coupled to the support member. The reflector comprises a reflecting member with a predetermined focal axis for reflecting a portion of electromagnetic radiation in a preselected direction from an electromagnetic transmissive envelope placed adjacent the reflector. The envelope comprises an elongated source of electromagnetic radiation extending between two points within the envelope and which is displaced from a straight line. Rotatable receiving assemblies mounted to the support member position the envelope adjacent to the reflector with the envelope axis substantially parallel to the focal axis where rotation of the envelope axis around the focal axis compensates for the displacement of the elongated source.

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 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.

Abstract: An evacuation aid for a high rise building comprising a wind cone lighting device which can be operated for a substantial period of time under emergency power conditions such as from a battery supply. The wind cone is lighted by a single light rotating with the wind cone and powered through slip ring assemblies.

Abstract: A light fixture having a reflector for directing light beams generally in a first direction, such as an indirect lighting reflector, which has a tab that is partially punched out and bent to reflect a restricted spot of light in an opposite direction. This permits the highlighting or illumination of an area on the back side of the reflector without extra bulbs and without ugly add-on reflectors.

Abstract: A hanger for mounting elongated members relative to a wall surface which permits alignment of the elongated member in a direction perpendicular to the surface, and also in both directions along the surface. The uses of the hangers find particular application in hanging elongated fluorescent light troffers or mounting tubes, and for mounting other devices such as a lighted hand rail or an unlighted hand rail for stairways.
