Abstract

A lighting device includes a housing and a light emitter coupled to the housing. A mounting plate is coupled to the housing and includes a front surface facing the housing and a rear surface opposite the front surface. The rear surface includes a snap-fit mounting feature and a rear connector portion. A first connector is coupled to the rear connector portion and operatively coupled to the light emitter.

First claim

What is claimed:

1. A lighting device comprising:
a housing;
a light emitter coupled to the housing;
a mounting plate coupled to the housing and having a front surface facing the housing and a rear surface opposite the front surface, the rear surface including a snap-fit mounting feature and a rear connector portion, wherein a wall extends from the rear surface of the mounting plate and is configured to extend into a junction box; and
a first connector coupled to the rear connector portion and operatively coupled to the light emitter, the first connector is a plug-style connector having a connector body secured to the mounting plate and extending from the rear surface away from the front surface so that at least a portion of the connector body is in a fixed position relative to the mounting plate, wherein the first connector is configured to connect to a second connector positioned in the junction box.

2. The lighting device of claim 1 , wherein the snap-fit mounting feature includes a cantilevered mounting arm.

3. The lighting device of claim 1 , wherein the rear connector portion includes a slot and the first connector extends through the slot.

4. The lighting device of claim 1 , wherein the first connector is a male connector configured to mate with a corresponding female second connector.

5. The lighting device of claim 1 , wherein the wherein the wall includes a central tab and an aperture.

6. The lighting device of claim 4 , wherein the first connector includes a female plug.

7. The emergency lighting device of claim 1 , wherein the mounting plate is snap-fit to the housing.

8. The lighting device of claim 6 , wherein the mounting plate includes a cantilevered arm extending from the front surface.

9. A lighting device comprising:
a housing;
a light emitter coupled to the housing;
a mounting plate coupled to the housing and having a front surface facing the housing and a rear surface opposite the front surface, wherein a wall extends from the rear surface of the mounting plate and is configured to extend into a junction box;
a first connector secured to the mounting plate and extending from the rear surface away from the front surface so that at least a portion of the first connector is in a fixed position relative to the mounting plate, the first connector being operatively connected to the light emitter; and
a second connector configured to be coupled to a power supply, wherein the first connector is configured to releasably mate with the second connector, and wherein the second connector is positioned in the junction box.

10. The lighting device of claim 9 , wherein the rear connector portion includes a slot and the first connector extends through the slot.

11. The lighting device of claim 9 , wherein the first connector includes a female connector and the second connector includes a male connector.

12. The lighting device of claim 9 , wherein the second connector is coupled to a mounting bracket.

13. The lighting device of claim 9 , wherein a cantilevered arm extends from the rear surface of the mounting plate.

14. A lighting assembly comprising:
a light assembly having a housing at least partially defining a chamber containing a control component for a light emitter and a mounting plate having a front portion facing the chamber and a rear portion positioned opposite the chamber, wherein a first, plug-style connector is secured to the mounting plate to extend from the rear portion away from the front portion so that at least a portion of the first connector body is in a fixed position relative to the mounting plate and a first snap-fit feature extends from the rear portion, and wherein a wall extends from the rear surface of the mounting plate into the junction box; and
a junction box comprising a plurality of walls, a second snap-fit feature provided on at least one of the walls; and
a second connector positioned in the junction box,
wherein the first snap-fit feature mates with the second snap fit feature and the first connector mates with the second connector.

15. The lighting assembly of claim 14 , wherein the first snap-fit feature includes a cantilevered arm and the second snap-fit feature includes a slot.

16. The lighting assembly of claim 14 , wherein the first connector includes a female connector and the second connector includes a male connector.

17. The lighting assembly of claim 14 , wherein the wall includes a central tab and an aperture.

18. The lighting assembly of claim 17 , wherein the wall includes a tab and an opening for receiving a fastener.

19. The lighting assembly of claim 14 , wherein the second connector is coupled to a mounting bracket.

20. A method of installing a quick-change lighting assembly comprising:
wiring a first electrical connector to a power supply, the first electrical connector having a plug-style connector body;
securing the first electrical connector in a junction box;
coupling a lighting assembly to the junction box, wherein the lighting assembly includes a mounting plate and a second electrical connector secured to and extending from the mounting plate so that at least a portion of the connector body is in a fixed position relative to the mounting plate, wherein a wall extends from the rear surface of the mounting plate into the junction box and wherein the second electrical connector mates with the first electrical connector when the lighting assembly is coupled to the junction box.
