Abstract

A surface mount luminaire includes a housing assembly formed by a light source housing and a housing cover that are removably coupled to each other. The light source housing includes a recessed structure that defines an inner cavity. The inner cavity houses a lighting assembly that is configured to emit light to an area that is to be illuminated. Further, the light source housing defines a second cavity that is disposed external to and around the recessed structure. The second cavity is enclosed by the housing cover and houses electrical components associated with the luminaire such that the electrical components are inset within the housing assembly of the luminaire. Further, the luminaire includes one or more gaskets that are coupled to the housing assembly to provide a seal that is configured to protect the one or more components disposed in the second cavity from environmental elements.

First claim

What is claimed is:

1. A light fixture comprising:
a housing assembly that comprises:
a light source housing having a first surface defining an inner cavity open toward a first direction and a second surface defining an outer cavity open toward a second direction, wherein the first direction is opposite to the second direction, wherein the first surface forms a recessed structure in the light source housing, the recessed structure extending in the second direction, and wherein the recessed structure comprises a wire routing opening for routing electrical wires from the outer cavity to the inner cavity; and
a housing cover removably coupled to the light source housing such that the housing cover encloses the outer cavity;

a lighting assembly comprising a light source member and a lens, the lighting assembly being coupled to the first surface of the light source housing and disposed in the inner cavity of the light source housing such that light emitted by the light source member exits the light fixture in the first direction; and
one or more electrical components associated with the light fixture, the one or more electrical components mounted on the housing cover and disposed in the outer cavity of the light source housing.

2. The light fixture of claim 1 , wherein the recessed structure comprises:
a top wall;
a first sidewall that extends substantially perpendicular to the top wall and in the first direction from a perimeter of the top wall;
a first flange that extends substantially horizontally and radially outward from a first bottom edge of the first sidewall; and
a second sidewall that extends substantially perpendicular to the first flange and in the first direction from an outer perimeter of the first flange.

3. The light fixture of claim 2 , wherein the light source housing further comprises:
a second flange that extends substantially horizontally and radially outwards from a second bottom edge of the second sidewall; and
a third sidewall that extends from an outer perimeter of the second flange to a top edge in the second direction such that the third sidewall forms an obtuse inner angle with the second flange, wherein the second surface of the recessed structure, the second flange and the third sidewall define the outer cavity.

4. The light fixture of claim 1 , wherein the housing cover comprises:
a base that is defined by an inner curved edge that defines a central aperture and an outer curved edge that is concentric with the inner curved edge; and
a component housing segment.

5. The light fixture of claim 4 , wherein the light fixture further comprises a component cover that is removably coupled to the housing cover and configured to house the one or more electrical components.

6. The light fixture of claim 1 , further comprising:
a first gasket that is disposed on a first surface of the housing cover such that it extends along a perimeter of the housing cover; and
a second gasket that is disposed on a second surface of the housing cover along a sealing wall of the housing cover, the sealing wall being disposed adjacent to and offset from an outer perimeter of the housing cover.

7. The light fixture of claim 2 , wherein the lighting assembly further comprises a reflector, and wherein the light source member and the reflector are coupled to the top wall of the recessed structure.

8. The light fixture of claim 2 , wherein the top wall comprises the wire routing opening.

9. A light fixture comprising:
a housing assembly that defines a first cavity configured to house one or more electrical components associated with the light fixture, wherein the housing assembly comprises:
a light source housing that comprises:
a base wall defined by an inner edge and an outer edge that is concentric with the inner edge;
a recessed structure extending substantially vertically in a first direction from the inner edge of the base wall such that a first surface of the recessed structure defines a second cavity that is open toward a second direction, the second direction being opposite the first direction, the recessed structure comprising a top wall and a sidewall structure that extends from a perimeter of the top wall to the first inner edge of the base wall; and
a light source coupled to the top wall on the first surface of the recessed structure and disposed in the second cavity to emit light in the second direction;

an outer sidewall extending in the first direction from the outer edge of the base wall such that the outer sidewall, the base wall, and a second surface of the recessed structure that is opposite to the first surface define the first cavity; and
a housing cover having a central opening through which a portion of the recessed structure extends.

10. The light fixture of claim 9 , wherein the sidewall structure of the recessed structure comprises:
a first sidewall that extends substantially perpendicular to the top wall and in the first direction from the perimeter of the top wall;
a first flange extending substantially horizontally and radially outward from a first bottom edge of the first sidewall; and
a second sidewall extending substantially perpendicular to the first flange and in the first direction from an outer perimeter of the first flange.

11. The light fixture of claim 9 , wherein the housing cover comprises:
a base defined by an inner curved edge and an outer curved edge that is concentric with the inner curved edge; and
a component housing segment, wherein the component housing segment is parallel to and vertically offset from a plane comprising the base.

12. The light fixture of claim 11 :
wherein the base of the housing cover comprises a pair of first mounting features formed therein, and
wherein the pair of first mounting features of the base of the housing cover is configured to engage a pair of second complementary mounting features of a mounting bracket to removably couple the light fixture to the mounting bracket.

13. The light fixture of claim 12 :
wherein each first mounting feature of the pair of first mounting features comprise a mounting slot, a mounting hole that is disposed adjacent the mounting slot, and a spring clip member that is coupled to the base such that a spring tab of the spring clip member extends through the mounting hole, and
wherein each second complementary mounting feature of the pair of second complementary mounting features comprise a locking arm that is substantially U-shaped.

14. The light fixture of claim 9 , further comprising a light source member.

15. The light fixture of claim 9 , further comprising a lens.

16. The light fixture of claim 9 , further comprising:
a first gasket that is disposed on a first surface of the housing cover and extending along a perimeter of the housing cover; and
a second gasket that is disposed on a second surface of the housing cover along a sealing wall of the housing cover, the sealing wall being disposed adjacent to and offset from an outer perimeter of the housing cover.

17. The light fixture of claim 11 , wherein the light fixture further comprises a component cover that is removably coupled to the component housing segment of the housing cover such that a component housing cavity is defined by the component cover and the housing cover.

18. The light fixture of claim 9 , further comprising a mounting bracket configured to mount the light fixture to a mounting surface.
