Abstract: The light fixture includes a frame, a substantially flat light emitting diode (LED) panel disposed within the frame, power circuitry disposed within at least one of a number of channels within the frame, and a central wire-way. The frame includes a bottom assembly and a top assembly coupled to the bottom assembly. The bottom assembly and the top assembly cooperate to form the channels within the frame. The bottom assembly has a back surface. The power circuitry is configured to electrically couple the substantially flat LED panel to an external AC power supply. The central wire-way is disposed adjacent the back surface of the bottom assembly and configured to route wiring to or from the power circuitry disposed within at least one of the channels within the frame.

Abstract: The present application is directed to a light fixture and associated retrofit lighting kit that includes a substantially flat light emitting diode panel. The light fixture can be employed in a variety of applications, including installation as a standalone fixture, a replacement for a fluorescent lighting unit and as a retrofit lighting kit to be used in connection with an existing fluorescent lighting unit.

Abstract: The light fixture includes a frame, an optically transmissive panel assembly, a set of light emitting diodes (LEDs), and driving circuitry. The frame has a frame length measured along a length axis and a frame width measured along a width axis, wherein the frame length is greater than the frame width. The optically transmissive panel assembly receives light from the set of light emitting diodes (LEDs) and emits light from an emission area in a patterned luminous intensity, using patterning optics adjacent a light guide plate. The driving circuitry is disposed within the frame and is operatively coupled to the set of LEDs and to a power supply external to the light fixture. The driving circuitry may include a first circuitry segment disposed within a first edge channel of the frame, and a second circuitry segment disposed within a second edge channel of the frame.

Abstract: An LED panel light fixture and method for assembling the same includes (a) selecting a set of specifications of the LED panel light fixture, the set of specifications comprising a fixture/base specification comprising a form factor of the LED panel light fixture; and a top specification comprising a visual feature of a top in accordance with the top specification; (b) providing a knock-down kit having parts including the top in accordance with the top specification, a frame in accordance with the fixture/base specification, an optically transmissive panel assembly, a set of light emitting diodes (LEDs), and driving circuitry; and (c) assembling the LED panel light fixture using parts of the knock-down kit. An LED panel lighting fixture kit includes a top and a base. The base includes a mounting mechanism that is accessible before joining the top to the base, but not accessible after joining the top to the base.

Abstract: The light fixture includes a light emitting panel assembly; and a power circuit module releasably attachable to the light emitting panel assembly. The light emitting panel assembly includes a frame, and a light emitting diode (LED) panel that is substantially flat and disposed within the frame and that includes an array of LEDs. The power circuit module includes a power circuit; a source electrical connector that electrically couples the power circuit to a power supply external to the light fixture; and a driver electrical connector that electrically couples the power circuit to the array of LEDs. The source electrical connector and driver electrical connector may be configured to be disconnected as the power circuit module is detached and separated from the light emitting panel assembly.
