Abstract

A light fixture includes an enclosure having a top side and an opposing underside, and a luminaire module. The luminaire module includes a panel, a plurality of LEDs, a first reflector, and a second reflector. The panel extends along the opposing underside of the enclosure. The plurality of LEDs are coupled to the panel and arranged in at least one row. The at least one row has a first lateral side and a second lateral side. The first reflector is coupled to the panel and disposed along the first lateral side of the plurality of LEDs. The second reflector are coupled to the panel and disposed along the second lateral side of the plurality of LEDs. The panel is releasably attached to the enclosure such that replacement of the panel simultaneously replaces the plurality of LEDs, the first reflector, and the second reflector.

First claim

What is claimed is:

1. A light fixture, comprising:
an enclosure having a top side and an opposing underside, wherein the enclosure includes a channel defined at least partially by the opposing underside;
a first luminaire module, including:
a first panel extending along the opposing underside of the enclosure and positioned on a first side of the channel;
a first plurality of LEDs coupled to the first panel and arranged in at least two rows, the at least two rows having a first lateral side, a second lateral side, and a central region;
a first reflector coupled to the first panel and disposed along the first lateral side of the at least two rows of LEDs, wherein the first reflector includes a first wall that is angularly offset relative to a first base;
a second reflector coupled to the first panel and disposed in the central region, between the at least two rows of LEDs, wherein the second reflector includes a second wall that is angularly offset relative to a second base and a third wall that is angularly offset relative to the second base, wherein the second wall and the third wall of the second reflector extend laterally inward and away from a pair of the at least two rows of LEDs such that the second reflector is configured to redirect light emitted by at least two rows of the first plurality of LEDs; and
a third reflector disposed on the second lateral side of the at least two rows of LEDs, wherein the third reflector includes a fourth wall that is angularly offset relative to a third base, wherein the first wall of the first reflector and the fourth wall of the third reflector extend laterally outward and away from the first plurality of LEDs,
wherein the first base, the second base, and the third base of the first reflector, the second reflector, and the third reflector, respectively, are coupled to the first panel,
wherein the first wall, the second wall, the third wall, and the fourth wall comprise a reflective material configured to redirect light emitted by the first plurality of LEDs thereby shaping a light output from the light fixture; and

a second luminaire module, including:
a second panel extending along the opposing underside of the enclosure and positioned on an opposing second side of the channel; and
a second plurality of LEDs coupled to the second panel;
wherein the first panel is releasably attached to the enclosure such that replacement of the first panel simultaneously replaces the first plurality of LEDs, the first reflector, and the second reflector; and
wherein the second panel is releasably attached to the enclosure, separate from the first panel, such that replacement of the second panel simultaneously replaces the second plurality of LEDs.

2. The light fixture of claim 1 , further comprising a driver coupled to the first plurality of LEDs, wherein the driver is fixed to the enclosure and disposed within the channel.

3. The light fixture of claim 1 , wherein the first panel is coupled to the enclosure with at least one of a screw, a twist-lock connector, and a snap-fit connector.

4. The light fixture of claim 1 , wherein the first panel and the enclosure comprise separate components coupled together, wherein the first panel comprises a first coating, and wherein the enclosure comprises a second coating different than the first coating.
