Abstract: An LED lighting control system incorporating a control IC for fast control of LED current in a switching Buck-type power supply through dedicated power supply control hardware with slow changing signals of temperature and input under control of firmware. The control IC optimizes the use of power from the source and optimizes the operating efficiency of the LED output while providing for a plurality of LED devices to be powered in parallel by a single controller.

Abstract: A lighting fixture frame and mounting panel apparatus that includes a frame formed with an interior wall circumscribing a central opening and a panel for mounting a lighting device. The frame is formed with inwardly projecting stop pads and resilient legs formed with inwardly projecting teeth, and the panel is received upwardly into the central opening until it is securely mounted in a panel slot formed between the lower surfaces of the pads and the upper surfaces of the teeth.
Abstract: A light fixture including a housing formed by a pan having parallel side walls terminating in mounting phalanges formed with O-ring rungs and further including retainer rails which engage the opposite side of a flexible lens to hold the lens against an O-ring in the O-ring runs to maintain a moisture resistant seal.

Abstract: A rectangular frame having side and end and side walls defining a downwardly opening receiving cavity for receipt upwardly therein of a pan having a laterally outwardly turned marginal flanges which overlie corresponding flanges in the frame and has mated mounting bores for receipt of mounting screws. Retains mounted on the opposite ends of the frame releasably engage the pan to hold it in position in the frame during shipping and storage and prior to mounting thereof.
Abstract: A light fixture with extruded wire way cover mount for quick engagement and disengagement of the wire way cover and fixture housing. The fixture housing is extruded to form a recessed channel with a pair of elongated, opposing retainer lips extending over the opposite sides of the channel to define respective retainer slots therebetween. A flexible wire way cover is provided and includes a pair of flanges for receipt in the respective retainer slots. A diffuser is also provided and is likewise formed with mounting flanges for receipt in respective diffuser retainer slots formed in the lateral side walls of the housing in overlying relation with the wire way cover.
Abstract: A fluorescent tube lighting fixture and method of fabrication characterized by the selection of a common channel housing including a central mounting bore wherein either a first circuit board device, including a single transistor mounting foot, or a second circuit board device, including two laterally spaced apart transistor mounting feet, may be selected for mounting to the common channel housing. To mount the first circuit board device to the channel housing, the first circuit board device is positioned on the channel housing and a fastener is inserted through a fastener bore of the single transistor mounting foot and mounting bore of the channel housing.
Abstract: An elongated transparent open ended tubular housing formed with an interior chamber for telescopical receipt of an elongated channel-shaped rail formed having opposed inturned longitudinal flanges defining therebetween passageways. A plurality of L-shaped mounting brackets are configured with respective horizontally disposed foot plates, the opposite marginal edges thereof forming sliders received slidably under the rail flanges. The opposite leg of the respective brackets then form vertically projecting mounting plates which mount respective sockets for receipt of the opposite ends of tubular electrical lamps to mount them with the bottom peripheral segments thereof recessed into said passageway. One mounting bracket is formed with an elongated strip disposed in heat exchange relationship with heat emitting electrical components to provide for efficient transfer to the channel which will act as a heat sink.
