## Abstract

A luminaire comprising: a chassis (100), the chassis (100) comprising: four walls joined to form a rectangular cavity, each wall of the four walls comprising: —a heat sink (107); —a wiring channel (111, 112); —a first receiving channel (114) on a first side of the heat sink (107); and —a second receiving channel (116) on a second side of the heat sink (107); a light emitting diode board (130) attached to a first wall of the four walls; a first extrusion (344) attached to a second wall of the four walls; a second extrusion (345) attached to a third wall of the four walls; wherein the light emitting diode board (130) comprises a first protrusion that fits into the first receiving channel and a second protrusion that fits into the second receiving channel; and wherein the light emitting diode board (130) rests on the heat sink (107) of the first wall when the first protrusion is fit into the first receiving channel and the second protrusion is fit into the second receiving channel.

## Claims

### Claim 1

A luminaire comprising:
a chassis, the chassis comprising:
four walls joined to form a rectangular cavity, each wall of the four walls comprising:
a heat sink;
a wiring channel;
a first receiving channel on a first side of the heat sink; and
a second receiving channel on a second side of the heat sink;
a light emitting diode board attached to a first wall of the four walls;
a first extrusion attached to a second wall of the four walls;
a second extrusion attached to a third wall of the four walls; wherein the light emitting diode board comprises a first protrusion that fits into the first receiving channel and a second protrusion that fits into the second receiving channel; and
wherein the light emitting diode board rests on the heat sink of the first wall when the first protrusion is fit into the first receiving channel and the second protrusion is fit into the second receiving channel.

### Claim 2 (depends on 1)

The luminaire of claim 1, wherein the chassis is separable into at least two components to provide access to the rectangular cavity.

### Claim 3 (depends on 1)

The luminaire of claim 1, wherein the rectangular cavity comprises one or more of a power supply, a battery, and a controller.

### Claim 4 (depends on 3)

The luminaire of claim 3, further comprising wiring extending from the light emitting diode board, through the wiring channel, and to the power supply.

### Claim 5 (depends on 1)

The luminaire of claim 1, wherein each wall of the four walls further comprise:
a third receiving channel adjacent to the first receiving channel; and
a fourth receiving channel adjacent to the second receiving channel.

### Claim 6 (depends on 5)

The luminaire of claim 5, wherein the first extrusion is attached to the third receiving channel and the fourth receiving channel of the second wall.

### Claim 7 (depends on 5)

The luminaire of claim 5, wherein the second extrusion is attached to the third receiving channel and the fourth receiving channel of the third wall.

### Claim 8 (depends on 1)

The luminaire of claim 1, further comprising:
a first end cap that attaches to a first end of the chassis; and
a second end cap that attaches to a second end of the chassis.

### Claim 9 (depends on 1)

The luminaire of claim 1, wherein each wall of the four walls further comprises at least one aperture for securing a suspension cable.

### Claim 10 (depends on 1)

The luminaire of claim 1, further comprising an aperture for receiving a power cable.

### Claim 11 (depends on 10)

The luminaire of claim 10, wherein the power cable electrically couples to a bus bar disposed within the rectangular cavity.
