LED light fixture and assembly method therefor
View Patent ↗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.
1. An LED (light emitting diode) panel lighting fixture, comprising:
a top, comprising:
a top frame including a bezel surrounding a light emitting area;
a base, comprising:
a circular base frame, wherein the top frame and the circular base frame are separate parts and the top frame is configured to be joined to the base frame to form an assembled frame;
an LED strip comprising a plurality of LEDs disposed within a channel of the circular base frame and adjacent a first edge surface at an indentation of an indented circular optically transmissive panel;
the indented circular optically transmissive panel, for distribution of light received from the LED strip at the first edge surface of the indented circular optically transmissive panel to the light emitting area;
an LED driver disposed within the channel of the circular base frame between a second edge surface of the indented circular optically transmissive panel and the circular base frame, the LED driver being configured to convert an AC power input from an external AC power supply to a DC power output for the LED strip;
wherein a mounting plate for the base contains a plurality of apertures including holes and slots configured in a circle, wherein the holes and slots are configured in a circle for securing the LED panel lighting fixture to a ceiling box that contains the external AC power supply.
2. The LED (light emitting diode) panel lighting fixture of claim 1 , wherein the plurality of apertures further includes a central opening of the mounting plate for the base, further comprising wiring carrying AC power in from the external AC power supply to the LED driver, wherein the wiring is routed into the base through the central opening of the mounting plate for the base.
3. The LED (light emitting diode) panel lighting fixture of claim 1 , wherein the base includes a power connector coupled to the LED driver as an additional component, and source power connector coupled to the external AC power supply as an additional component.
4. The LED (light emitting diode) panel lighting fixture of claim 1 , further comprising mechanical fasteners for surface mounting the LED panel lighting fixture to a surface, wherein the mechanical fasteners are accessible before joining the top to the base but are covered by the top and are not accessible after joining the top to the base.
5. The LED (light emitting diode) panel lighting fixture kit of claim 1 , wherein the base includes a mechanism for mounting the base within a recess in a wall or ceiling, and wherein the top includes a trim ring for sealing the recess.
6. The LED (light emitting diode) panel lighting fixture of claim 1 , wherein the second edge of the top frame comprises a first edge wall portion, that forms an interference fit with a second edge wall portion of the base frame.
7. The LED (light emitting diode) panel lighting fixture of claim 1 , wherein the holes and slots configured in a circle are arranged to accommodate several types of the ceiling box that contains the external AC power supply.
