Field-serviceable flat panel lighting device

摘要

The light fixture includes a light emitting panel assembly including a frame and a substantially flat light emitting diode (LED) panel disposed within the frame. The substantially flat light emitting diode (LED) panel has an array of light emitting diodes (LEDs). The light fixture further includes a power circuitry module, with a power circuit. The power circuitry module is disposed within the frame adjacent an edge of the frame, and is releasably attachable to the light emitting panel assembly. A decouplable source electrical connector electrically couples the power circuit to an AC power supply external to the light fixture, and a decouplable driver electrical connector electrically couples the power circuit to the array of light emitting diodes (LEDs). The source electrical connector and driver electrical connector may be configured to be decoupled as the power circuitry module is detached and separated from the light emitting panel assembly.

1. A light fixture comprising:
(a) a light emitting panel assembly comprising a frame and a substantially flat light emitting diode (LED) panel disposed within the frame, said substantially flat light emitting diode (LED) panel including an optically transmissive panel, and an array of light emitting diodes (LEDs) disposed adjacent an edge of the optically transmissive panel and disposed adjacent a first edge of the frame; (b) a power circuitry module disposed within the frame adjacent a second edge of the frame and releasably attachable to the light emitting panel assembly, said power circuitry module including a power circuit; (c) a decouplable source electrical connector that electrically couples the power circuit to an AC power supply external to the light fixture, wherein the power circuit converts AC power to DC power to drive the array of light emitting diodes (LEDs); and (d) a decouplable driver electrical connector that electrically couples the power circuit to the array of light emitting diodes (LEDs); wherein the substantially flat light emitting diode (LED) panel and the power circuitry module are disposed side-by-side within the frame; and wherein the frame defines an aperture adjacent the second edge of the frame to access the power circuitry module.
