Abstract

A luminaire includes a housing, a plurality of fins, and an LED module. The housing includes a first compartment having a top wall, a side wall extending from the top wall, and a first opening in the side wall. The plurality of fins is positioned in the first compartment so that at least one fin is in communication with the first opening. The LED module is connected to at least one of the heat fins and includes a PCB, a bezel, and at least one LED.

Claims

1. A luminaire comprising:

a housing including a first compartment having a top wall, a side wall extending from the top wall, and a first opening in the side wall;

a plurality of fins positioned in the first compartment directly connected to and extending from the top wall with at least one fin-extending through the first opening and having an outer edge substantially aligned with a surface of the side wall; and

an LED module directly connected to at least one of the heat fins opposite the top wall, the LED module including a PCB, a bezel, and at least one LED,

wherein the fins are configured to dissipate heat from the LEDs such that the configuration of the housing, fins, and LED modules allows air to flow underneath of the housing, through the interior, and through the first opening.

2. The luminaire of claim 1, wherein

the housing further comprises a driver compartment housing a driver, wherein the driver compartment is separated from the first compartment by a wall.

3. The luminaire of claim 1, wherein

the housing and the plurality of fins are integrally formed.

4. The luminaire of claim 1, wherein

the first compartment further comprises a second opening opposite the first opening.

5. The luminaire of claim 1, wherein

at least one heat fin is exposed to an external environment through the bottom of the housing.

6. The luminaire of claim 1, wherein the LED module is removable from at least one of the heat fins.

7. A luminaire comprising:

a housing including a first compartment having an interior, a top wall, a side wall extending from the top wall, and an opening in the side wall;

a plurality of cantilevered fins positioned in the interior, the plurality of cantilevered fins having a plurality of fixed ends and a plurality of bottom surfaces opposite the fixed ends, the bottom surfaces substantially planar with and spaced from one another; and

an LED assembly directly connected to the bottom surface of at least one of the fins,

wherein the fins are configured to dissipate heat from the LEDs such that the configuration of the housing, fins, and LED modules allows air to flow underneath of the housing, through the interior, and through the first opening.

8. The luminaire of claim 7, further comprising

at least two LED assemblies connected to the plurality of heat fins in a plane substantially parallel to a horizontal ground plane.

9. The luminaire of claim 7, wherein

the LED assembly comprises a PCB, a bezel, an optic, and an LED.

10. The luminaire of claim 7, wherein

the fins extend from a first side of the interior to a second side of the interior.

11. The luminaire of claim 7, wherein

at least one of the fins is exposed through the opening and from a bottom of the housing.

12. The luminaire of claim 7, wherein

at least one of the fins includes an enlarged portion extending from the bottom surface and aligned with a light emitting device.

13. The luminaire of claim 7, wherein

at least one of the plurality of fins includes a channel defined therein.

14. The luminaire of claim 7, wherein the LED assembly is removable from at least one of the heat fins.
