Abstract

A high-bay luminaire includes an upper housing having an outer wall defining an interior compartment. A plurality of first heat fins extend from the exterior of the outer wall. An angled wall extends from the outer wall at an oblique angle toward the center of the interior compartment. A base is connected to the upper housing. A light emitter is connected to the base. A lens is connected to the base and positioned below the light emitter. A driver is connected to the angled wall and operatively connected to the light emitter.

Claims

1. A high-bay luminaire comprising:

an upper housing having an outer wall defining an interior compartment, wherein a plurality of first heat fins extend from the exterior of the outer wall and an angled wall extends from the outer wall at an oblique angle toward the center of the interior compartment;

a base connected to the upper housing;

a light emitter connected to the base;

a lens connected to the base and positioned below the light emitter; and

a driver connected to the angled wall and operatively connected to the light emitter.

2. The high-bay luminaire of claim 1, wherein the base includes a plurality of second fins aligned with the first fins.

3. The high-bay luminaire of claim 1, wherein the driver is connected to the angled wall by a driver bracket.

4. The high-bay luminaire of claim 3, wherein the driver bracket has a substantially V-shaped configuration including a first side and a second side connected to a lower wall, and wherein the driver is positioned by the first side.

5. The high-bay luminaire of claim 4, wherein a second driver is positioned by the second side.

6. The high-bay luminaire of claim 1, wherein the upper housing includes a bottom wall and a flange extending from the bottom wall, and the base includes a hub extending from an inner portion to mate with the flange.

7. The high-bay luminaire of claim 1, wherein an airflow channel is defined between the upper housing and the base to reduce heat transfer between the upper housing and the base.

8. A high-bay luminaire comprising:

an upper housing having an outer wall defining an interior compartment, wherein a plurality of first heat fins extend from the exterior of the outer wall and a first angled wall extends from the outer wall at an oblique angle toward the center of the interior compartment and a second angled wall extends from the outer wall at an oblique angle toward the center of the interior compartment;

a base connected to the upper housing;

a light emitter connected to the base;

a lens connected to the base and positioned below the light emitter; and

a driver bracket positioned in the interior compartment and configured to retain a first driver against the first angled wall.

9. The high-bay luminaire of claim 8, wherein the driver bracket includes a lower wall, a first side extending from the lower wall at an oblique angle and a second side extending from the lower wall at an oblique angle.

10. The high-bay luminaire of claim 9, wherein a first ledge extends from the first angled wall and a second ledge extends from the second angled wall, and wherein a first flange extends from the first side and a second flange extends from the second side, and wherein the first tab engages the first ledge and the second tab engages the second ledge.

11. The high-bay luminaire of claim 9, wherein a pair of tabs extend from the first side toward the first angled wall.

12. The high-bay luminaire of claim 8, wherein a first driver is retained against the first angled wall by the driver bracket.

13. The high-bay luminaire of claim 12, wherein a spacer is connected to the second side of the driver bracket.

14. The high-bay luminaire of claim 12, wherein a second driver is retained against the second angled wall by the driver bracket.

15. The high-bay luminaire of claim 8, further comprising a sensor removably connected to and extending from the base.

16. A high-bay luminaire comprising:

an upper housing having a bottom wall and an outer wall defining an interior compartment, wherein a plurality of first heat fins extend from the exterior of the outer wall;

a base connected to the upper housing, wherein the base includes a plurality of second fins aligned with and spaced from the first fins and an inner section spaced from and facing the bottom wall;

a light emitter connected to the base;

a lens connected to the base and positioned below the light emitter; and

a driver positioned in the interior compartment,

wherein an airflow channel is defined by the space between the bottom wall and the inner section and the space between the first fins and second fins.

17. The high-bay luminaire of claim 16, wherein a flange extends from the bottom wall and a hub extends from the inner portion to mate with the flange.

18. The high-bay luminaire of claim 16, wherein the base includes an outer section and a middle section positioned between the outer section and the inner section, and wherein the outer section, middle section, and inner section are spaced vertically from each other.

19. The high-bay luminaire of claim 18, wherein the second fins extend from an outer edge of the inner section to the outer section.

20. The high-bay luminaire of claim 16, wherein the upper housing includes an angled wall extending from the outer wall at an oblique angle toward the center of the interior compartment, and wherein a driver bracket having substantially V-shaped configuration retains the driver against the angled wall.
