High lumen high-bay luminaire with heat dissipating upper housing defining cavity for driver
A high-bay luminaire includes an upper housing having an outer wall with an outer wall having a plurality of first heat fins extending therefrom, and an interior surface defining an interior compartment with an angled wall; 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 by a driver bracket and positioned adjacent the interior surface.
1. A high-bay luminaire comprising:
an upper housing having an outer wall including an exterior surface and an interior surface, the interior surface defining an interior compartment, and a plurality of first heat fins extending from the exterior surface;
a base connected to the upper housing;
a light emitter removably connected to the base;
a lens connected to the base and positioned below the light emitter; and
a driver connected to a driver bracket in the upper housing,
wherein the driver bracket positions and supports the driver adjacent the interior surface,
wherein the outer wall includes an angled portion that extends at an oblique angle toward the center of the interior compartment, and the driver is connected to the angled portion by the driver bracket.
2. The high-bay luminaire of claim 1 , wherein the driver includes a driver housing having a longitudinal axis and the driver bracket supports the driver so that the longitudinal axis extends through the upper housing toward the base.
3. 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.
4. 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.
5. The high-bay luminaire of claim 1 , 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.
6. The high-bay luminaire of claim 5 , wherein a second driver is positioned by the second side.
7. A high-bay luminaire comprising:
an upper housing having an outer wall, a bottom wall, and a flange extending from the bottom wall, wherein the outer wall includes an exterior surface and an interior surface, the interior surface defining an interior compartment;
a base connected to the upper housing, the base having a central region and a hub extending from the central region toward the upper housing, wherein the hub mates with the flange to define a conduit;
a light emitter connected to the base; and
a driver bracket positioned in the interior compartment and configured to support and retain a first driver to the outer wall,
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.
8. The high-bay luminaire of claim 7 , wherein the hub extends inside of the flange.
9. The high-bay luminaire of claim 7 , wherein the hub and the flange have a cylindrical configuration.
10. The high-bay luminaire of claim 7 , wherein at least a portion of the bottom wall of the upper housing is spaced from at least a portion of the central region of the base to define an airflow channel between the upper housing and the base.
11. The high-bay luminaire of claim 7 , wherein the upper housing includes an open top and a cover is pivotally connected to the upper housing.
12. The high-bay luminaire of claim 7 , further comprising a sensor removably connected to and extending from the base.
13. The high-bay luminaire of claim 7 , wherein the upper housing includes a first angled portion and a second angled portion extending into the interior compartment.
14. The high-bay luminaire of claim 13 , wherein a first driver is retained against the first angled portion by the driver bracket.
15. 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 an exterior surface of the outer wall;
a base connected to the upper housing, the base includes a plurality of second fins separated from the first fins to define a first space, and an inner section facing but separated from the bottom wall to define a second space; and
a light emitter connected to the base;
wherein an airflow channel is defined by the first and second-spaces,
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, and
wherein a flange extends from the bottom wall and a hub extends from the base to mate with the flange.
16. The high-bay luminaire of claim 15 , wherein an angled transition separates the outer section and the middle section.
17. The high-bay luminaire of claim 15 , wherein the second fins are aligned with the first fins.
