Abstract

A lighting device includes a cover portion configured to have a hinged connection for mounting on a housing. The cover portion includes a light emitting diode (LED) and a mixing chamber having a reflective internal surface for receiving light from the LED. A phosphorescent lens is disposed opposite the LED and is configured to reflect light from the LED back to the mixing chamber and to emanate absorbed light from the lens to a surrounding region outside of the mixing chamber. An LED driver circuit is configured to power the LED, the LED driver circuit being electrically connected to a power source. Other embodiments are also disclosed.

Claims

1. A lighting device, comprising:

a hinged portion configured to be hingedly connected to a mount, the hinged portion including;

at least one light emitting diode (LED);

a mixing chamber having a reflective internal surface for receiving and reflecting light from the at least one LED; and

a lens disposed opposite the at least one LED and configured to reflect light from the at least one LED back to the mixing chamber and to emanate absorbed light from the lens to a surrounding region outside of the mixing chamber; and

an LED driver circuit configured to power the at least one LED, the LED driver circuit being electrically connected to a power source;

wherein the hinged portion includes rails which slidably receive portions of a light assembly including the at least one LED to permit mounting of the light assembly on the hinged portion.

2. The lighting device as recited in claim 1, further comprising a locking mechanism to secure the hinged portion.

3. The lighting device as recited in claim 1, wherein the LED driver circuit includes brackets configured to mount the LED driver circuit without using tools.

4. The lighting device as recited in claim 3, wherein the brackets are spring loaded.

5. The lighting device as recited in claim 1, further comprising a plurality of lighting assemblies mounted on the hinged portion.

6. The lighting device as recited in claim 1, wherein the mixing chamber includes a reflector portion having an apex that runs parallel to a longitudinal axis of the lighting device, and the at least one LED being in optical communication with the reflective internal surface through openings at the apex.

7. The lighting device as recited in claim 6, wherein the mixing chamber includes reflective end plates transversely disposed to the apex on end portions of the reflector portion.

8. The lighting device as recited in claim 1, wherein the mixing chamber includes a conductive material and functions as a heat sink for the at least one LED.

9. The lighting device as recited in claim 1, wherein the at least one LED includes at least one emergency LED activated by an emergency circuit during a power outage.

10. A lighting device, comprising:

a hinged portion configured to be hingedly connected to a mount, the hinged portion including;

a hinge to open the hinged structure; and

a lighting assembly, including;

at least one light emitting diode (LED);

a mixing chamber having a reflective internal surface for receiving and reflecting light from the at least one LED; and

a lens disposed opposite the at least one LED and configured to reflect light from the at least one LED back to the mixing chamber and to emanate absorbed light from the lens to a surrounding region outside of the mixing chamber;

wherein the hinged portion includes rails which slidably receive portions of the light assembly to permit mounting of the light assembly on the hinged portion.

11. The lighting device as recited in claim 10, further comprising a locking mechanism to secure the lighting assembly.

12. The lighting device as recited in claim 10, further comprising an LED driver circuit configured to power the at least one LED, the LED driver circuit being electrically connected to a power source.

13. The lighting device as recited in claim 12, wherein the LED driver circuit includes brackets.

14. The lighting device as recited in claim 13, wherein the brackets are spring loaded.

15. The lighting device as recited in claim 10, wherein the mixing chamber includes a reflector portion having an apex that runs parallel to a longitudinal axis of the lighting device, and the at least one LED being in optical communication with the reflective internal surface through openings at the apex.

16. The lighting device as recited in claim 10, wherein the hinge is configured to permit access to the lighting assembly without using tools.

17. The lighting device as recited in claim 10, wherein the mixing chamber includes a conductive material and functions as a heat sink for the at least one LED.

18. The lighting device as recited in claim 10, wherein the at least one LED includes at least one emergency LED activated by an emergency circuit during a power outage.

19. A lighting device, comprising:

a hinged portion configured to be hingedly connected to a mount, the hinged portion including;

at least one light emitting diode (LED);

a mixing chamber having a reflective internal surface for receiving and reflecting light from the at least one LED, wherein the mixing chamber includes a reflector portion having an apex that runs parallel to a longitudinal axis of the lighting device, and the at least one LED being in optical communication with the reflective internal surface through openings at the apex; and

a lens disposed opposite the at least one LED and configured to reflect light from the at least one LED back to the mixing chamber and to emanate absorbed light from the lens to a surrounding region outside of the mixing chamber; and
