|20130088882||LIGHT FIXTURE WITH PERIPHERAL COOLING CHANNELS - An illustrative light fixture includes an emitter housing and airflow cooling channels. The airflow cooling channels are defined in the space between opposite edges of the emitter housing and a rim around the periphery of at least the opposite edges of the emitter housing. The airflow channels are further defined by fins spanning between the rim and opposite edges and spanning across a side of the housing opposite the illumination side.||04-11-2013|
|20130088865||LIGHT FIXTURE WITH INTERCHANGEABLE HEATSINK TRAYS AND REFLECTORS - An illustrative lighting system provides a single light housing and an associated lens cover that together interchangeably receive one of a selection of heat sink trays and one of a selection of light reflectors. Each of the selection of heat sink trays includes a different number and/or orientation of light emitter packages. Each the selection of light reflectors includes openings and surfaces matching the number and orientation of light emitter packages for one of the selection of heat sink trays.||04-11-2013|
|20120325982||MULTIPLE ANGLE MOUNTING ARM FOR LIGHT FIXTURES - An illustrative mounting arm for a light fixture provides multiple tilt angles based on the selected orientation of components of the mounting arm. The mounting arm includes a first and second arm portion, each having opposite ends oriented at different relative angles to provide the multiple tilt angles for the light. A support end arm or second arm portion connects directly or indirectly to a wall or other support structure. An intermediate or first arm portion couples between the second arm portion and a mounting pad portion of the light fixture. Each of the first and second arm portions are rotatable in orientation, thus changing the orientation of the angle ends, each combination of possible arm portion orientations displacing the light fixture and therefore the illumination pattern at a different elevation angle relative to the support structure.||12-27-2012|
|20120319591||PHOTOCELL CONTROLLED LED DRIVER CIRCUIT - An illustrative LED driver circuit includes an automatic on and off control function using a light sensing circuit having a light sensing element reacting to ambient light. The circuit uses flyback converter topology and a power factor correction (PFC) controller. The light sensing function is provided by coupling the light sensing circuit to a monitoring/disable function of the PFC controller, thus providing automatic on and off control of the LED driver circuit by using a light sensing element such as a photocell.||12-20-2012|
|20110286219||LED Housing with Heat Transfer Sink - An illustrative thermally managed light includes a light source, for example an LED array, a heatsink having a tapered outer surface, the light source thermally coupled with the heatsink, a housing having a tapered interior surface portion, and a securing device coupling the heatsink and the rear end of the housing. The securing device, for example a tensioning device, adapted to retain the outer surface of the heatsink in thermal contact with the tapered interior surface of the housing, thus transferring and dissipating the heat from the light source into the environment around the housing.||11-24-2011|
|20090257233||Adjustable Reflector Luminaire - The disclosure provides a luminaire having an adjustable light reflector affording a selection of flood pattern lighting.||10-15-2009|
