Abstract

A luminaire includes at least a cover and a mounting plate. The mounting plate includes one or more vertical protrusions and one or more horizontal protrusions that are substantially perpendicular to each other. Further, the mounting plate includes a tab that is substantially perpendicular to the one or more horizontal protrusions. The cover includes a pair of top apertures and a tab aperture. During installation of the luminaire, the cover is hung from the mounting plate by inserting each horizontal protrusion of the mounting plate through the respective top aperture of the cover. Alternatively, the cover is hung from the mounting plate by inserting the tab of the mounting plate through the tab aperture of the cover. After installation, the cover may be secured to the mounting plate by inserting the pair of vertical protrusions of the mounting plate through the pair of top apertures of the cover.

Claims

1. A luminaire comprising:

a mounting plate comprising a plurality of vertical protrusions disposed along a top edge of the mounting plate and a plurality of horizontal protrusions disposed along an inner surface of the mounting plate; and

a cover comprising a plurality of top apertures and a light source coupled to a driver;

wherein the plurality of horizontal protrusions are inserted into the plurality of top apertures such that the driver can be coupled to a power source during installation of the luminaire, and

wherein the plurality of vertical protrusions are inserted into the plurality of top apertures after the installation and when the luminaire is operational.

2. The luminaire of claim 1:

wherein the mounting plate further comprises apertures for securing the mounting plate to a surface, and

wherein the mounting plate has an offset shape that provides the luminaire a clearance from the surface when the mounting plate is directly attached to the surface.

3. The luminaire of claim 1, wherein the mounting plate further comprises one or more brackets for attaching the mounting plate to a surface.

4. The luminaire of claim 1, wherein the mounting plate further comprises an aperture that permits a cable from the power source to pass therethrough.

5. The luminaire of claim 1, wherein the driver is mounted to an interior surface of the cover.

6. A luminaire comprising:

a mounting plate comprising a plurality vertical protrusions disposed along a top edge of the mounting plate and a tab disposed along the top edge of the mounting plate;

a cover comprising a plurality of top apertures, a tab aperture, and a light source coupled to a driver;

wherein the tab is inserted into the tab aperture such that the driver can be coupled to a power source during installation of the luminaire, and

wherein the plurality of vertical protrusions are inserted into the plurality of top apertures after the installation and when the luminaire is operational.

7. The luminaire of claim 6:

wherein the mounting plate further comprises apertures for securing the mounting plate to a surface, and

wherein the mounting plate has an offset shape that provides the luminaire a clearance from the surface when the mounting plate is directly attached to the surface.

8. The luminaire of claim 6, wherein the mounting plate further comprises one or more brackets for attaching the mounting plate to a surface.

9. The luminaire of claim 6, wherein the mounting plate further comprises an aperture that permits a cable from the power source to pass therethrough.

10. The luminaire of claim 6, wherein the driver is mounted to an interior surface of the cover.

11. A method for installing a luminaire comprising:

securing a mounting plate to a support;

inserting horizontal protrusions on an inner surface of the mounting plate into top apertures in a cover so that the cover hangs from the mounting plate;

connecting a driver to a power source, the driver coupled to a light source disposed within the cover; and

removing the cover from the horizontal protrusions and inserting vertical protrusions on a top edge of the mounting plate into the top apertures thereby securing the cover to the mounting plate.

12. The method of claim 11, wherein the mounting plate is secured to the support via apertures in the mounting plate.

13. The method of claim 11, wherein the mounting plate is secured to the support via a bracket.

14. The method of claim 11, wherein the driver is connected to the power source by a cable that passes through an aperture in the mounting plate.

15. The method of claim 11, wherein the driver is mounted to an interior surface of the cover.

16. A method for installing a luminaire comprising:

securing a mounting plate to a support;

inserting a tab on a top edge of the mounting plate into a tab aperture in a cover so that the cover hangs from the mounting plate;

connecting a driver to a power source, the driver coupled to a light source disposed within the cover; and

removing the cover from the tab and inserting vertical protrusions on the top edge of the mounting plate into the top apertures thereby securing the cover to the mounting plate.

17. The method of claim 16, wherein the mounting plate is secured to the support via apertures in the mounting plate.

18. The method of claim 16, wherein the mounting plate is secured to the support via a bracket.

19. The method of claim 16, wherein the driver is connected to the power source by a cable that passes through an aperture in the mounting plate.

20. The method of claim 16, wherein the driver is mounted to an interior surface of the cover.
