Abstract:
An LED architectural luminaire (100) comprising a gull wing reflector (1), an LED mounting plate (200) and a central lens (9). The mounting plate (200) is disposed in said reflector (1) and includes a central flat mounting surface (201) flanked by a pair of angled mounting surfaces (202A, 202B), each of the mounting surfaces includes a strip of LEDs (3, 4A, 4B). The central lens (9) is disposed over and hingeably removabley connected to the mounting plate (200). End caps (8), light seals (6), and optional gaskets (7) are disposed on the ends of the luminaire.
Abstract:
Systems and methods for controlling a light emitting diode (LED) system having a plurality of LED arrays are provided. The lighting system can include a dimmable LED driver circuit configured to provide a driver output suitable for providing a driver current to the LED arrays. A current splitter circuit can be provided between the LED driver circuit and the plurality of LED arrays to control the ratio of current from the driver output provided to each of the plurality of LED arrays. The current splitter circuit can be configured to control the current ratio provided to the plurality of LED arrays independently of the driver output according to a current ratio control curve based at least in part on a variable reference signal provided at the current splitter circuit.
Abstract:
An LED architectural luminaire (100) for providing the lighting characteristics of a fluorescent luminaire comprises an LED mounting plate (21) having angled sides (30) for mounting strips of LEDs (22) to allow the LEDs to illuminate the entire face of the luminaire to achieve bat-wing light distribution and a favorable spacing criteria of about 1.5.
