## Abstract

A lighting fixture can include a housing and a plurality of modules positioned within the housing. The plurality of modules can be distributed along a front portion of the housing. Each module of the plurality of modules includes a plurality of light emitting diodes and is independently mountable in the housing such that a number of modules in the plurality of modules is selectable.

## Claims

### Claim 1

A lighting fixture, comprising:
a housing; and
a plurality of modules positioned within the housing, each module of the plurality of modules comprising a plurality of light emitting diodes, the plurality of modules distributed along a circumferential direction at a front portion of the housing, each module of the plurality of modules independently mountable in the housing such that a number of modules in the plurality of modules is selectable.

### Claim 2 (depends on 1)

The lighting fixture of claim 1, wherein each module of the plurality of modules has a common shape.

### Claim 3 (depends on 1)

The lighting fixture of claim 1, wherein each module of the plurality of modules has an inner edge and an outer edge that are spaced along a radial direction, a width of each module of the plurality of modules along the circumferential direction tapering from the outer edge to the inner edge, the inner edge of each module of the plurality of modules positioned proximate a central axis of the housing.

### Claim 4 (depends on 3)

The lighting fixture of claim 3, wherein each module of the plurality of modules has a pair of opposing side edges that extend along the radial direction between the inner edge and the outer edge, the pair of opposing side edges defining an angle, the angle between the pair of opposing side edges being no greater than one hundred and twenty degrees and no less than thirty degrees.

### Claim 5 (depends on 1)

The lighting fixture of claim 1, wherein the plurality of modules comprises no less than two modules and no greater than twelve modules.

### Claim 6 (depends on 5)

The lighting fixture of claim 5, wherein the plurality of modules is six modules.

### Claim 7 (depends on 1)

The lighting fixture of claim 1, further comprising a support body positioned within the housing, each module of the plurality of modules mounted to the support body.

### Claim 8 (depends on 7)

The lighting fixture of claim 7, wherein each module of the plurality of modules comprises a heat sink with a plurality of fins that extend away from the front portion of the housing, the heat sink of each module of the plurality of modules mounted to the support body.

### Claim 9 (depends on 8)

The lighting fixture of claim 8, wherein the heat sink of each module of the plurality of modules is fastened to the support body.

### Claim 10 (depends on 8)

The lighting fixture of claim 8, wherein the fins on each heat sink are all vertically oriented such that a plurality of vertical air flow paths is defined within the heat sinks of the plurality of modules.

### Claim 11 (depends on 8)

The lighting fixture of claim 8, wherein the heat sinks of the plurality of modules are all commonly shaped.

### Claim 12 (depends on 8)

The lighting fixture of claim 8, wherein the housing comprises a grill that extends around the heat sinks of the plurality of modules along the circumferential direction.

### Claim 13 (depends on 1)

The lighting fixture of claim 1, further comprising one or more drivers, the housing comprising a driver casing positioned at a rear portion of the housing, the one or more divers positioned within the driver casing and operatively coupled to the plurality of modules.

### Claim 14 (depends on 13)

The lighting fixture of claim 13, wherein the driver casing is a removable driver casing.

### Claim 15 (depends on 13)

The lighting fixture of claim 13, wherein the plurality of modules is operable by one or more remote drivers, the one or more remote drivers positioned outside of the housing.

### Claim 16 (depends on 1)

The lighting fixture of claim 1, further comprising at least one plug, the at least one plug and the plurality of modules distributed along the circumferential direction at the front portion of the housing.

### Claim 17 (depends on 16)

The lighting fixture of claim 16, wherein the at least one plug and the plurality of modules collectively extend three hundred and sixty degrees along the circumferential direction at the front portion of the housing.
