Flat panel lighting device and driving circuitry

摘要

The light fixture includes a frame configured to define a channel, and a substantially flat light emitting diode (LED) panel disposed within the frame. Power circuitry is disposed within the first channel, the power circuitry being configured to electrically couple the substantially flat LED panel to an external AC power supply. The power circuitry is sized to be positioned within the first channel and has a length and a width, the length-to-width ratio being at least 5 to 1, and optionally at least 10 to 1. The power circuitry is configured to convert an AC input into a DC output suitable for powering the substantially flat light emitting diode (LED) panel. The substantially flat light emitting diode (LED) panel includes an optically transmissive panel, and an array of LEDs disposed adjacent to an edge of the optically transmissive panel and disposed adjacent at least one edge of the frame.

主权项

1. A light fixture comprising:
a frame having a thickness of no more than about 1.0 inches and including a first portion of the frame and a second portion of the frame, wherein the first portion of the frame defines a first channel between a first edge of an optically transmissive panel and a first outer edge of the frame; a substantially flat light emitting diode (LED) panel disposed within the frame, wherein the substantially flat LED panel includes an LED strip and the optically transmissive panel, and the optically transmissive panel is configured to distribute light received at a light-input edge of the optically transmissive panel from the LED strip, the LED strip comprising a plurality of LEDs mounted to the second portion of the frame adjacent the light-input edge of the optically transmissive panel; and a first LED driver supported by the first portion of the frame and housed entirely within the first channel adjacent the first outer edge of the frame, wherein the first LED driver is configured to receive an AC input from an external AC power supply and to provide a DC output to the LED strip.
