Abstract

Emergency ballasts for powering fluorescent lights during power outages that have a reduced profile and do not require a bulky wiring tail. The emergency ballasts may include an external header that is associated with the internal circuitry of the ballast. A connector associated with the wiring of the other lighting fixture components may be inserted into or otherwise connected to the emergency ballast'"'"'s header.

Claims

1. An emergency lighting ballast for use with fluorescent fixtures, comprising:

(a) a ballast housing, the ballast housing substantially surrounding internal circuitry of the ballast and a rechargeable power source; and

(b) a header, at least a portion of which protrudes through the ballast housing, the header electrically associated with the internal circuitry;

wherein the header comprises one or more connection points, the connection points accessible from outside the ballast housing and electrically connecting one or more external wires to the internal circuitry.

2. The emergency lighting ballast of claim 1, wherein the external wires are directly connected to the connection points of the header.

3. The emergency lighting ballast of claim 1, wherein the external wires are electrically connected to the connection points of the header by at least one external connector.

4. The emergency lighting ballast of claim 3, wherein the at least one external connector comprises a multi-pin connector or a four pin connector.

5. The emergency lighting ballast of claim 3, wherein the at least one external connector comprises a multi-pin connector and a four pin connector.

6. The emergency lighting ballast of claim 3, wherein the at least one external connector is electrically connected to a pilot light or a test switch.

7. The emergency lighting ballast of claim 3, wherein the at least one external connector is electrically connected to a pilot light and a test switch.

8. The emergency lighting ballast of claim 3, wherein the at least one external connector comprises a poke-home connector.

9. The emergency lighting ballast of claim 8, wherein the at least one external connector comprises a male connector and wherein the header comprises a female connector.

10. The emergency lighting ballast of claim 1, wherein the internal circuitry and the header are associated with a circuit board.

11. An emergency lighting ballast for use with fluorescent fixtures, comprising:

(a) a ballast housing, the ballast housing substantially surrounding internal circuitry of the ballast and a rechargeable power source; and

(b) a header, at least a portion of which protrudes through the ballast housing, the header electrically associated with the internal circuitry;

wherein the header comprises one or more connection points, the connection points accessible from outside the ballast housing and electrically connecting one or more external wires to the internal circuitry and wherein the external wires are electrically connected to the connection points of the header by at least one external connector.

12. The emergency lighting ballast of claim 11, wherein the at least one external connector comprises a multi-pin connector and a four pin connector.

13. The emergency lighting ballast of claim 11, wherein the at least one external connector is electrically connected to a pilot light or a test switch.

14. The emergency lighting ballast of claim 11, wherein the at least one external connector comprises a poke-home connector.

15. The emergency lighting ballast of claim 11, wherein the at least one external connector comprises a male connector and wherein the header comprises a female connector.

16. The emergency lighting ballast of claim 11, wherein the internal circuitry and the header are associated with a circuit board.

17. A method of installing an emergency lighting ballast in a fluorescent light fixture, comprising:

(a) locating and securing an emergency lighting ballast in a fluorescent light fixture, the emergency lighting ballast comprising;

(i) a ballast housing, the ballast housing substantially surrounding internal circuitry of the ballast and a rechargeable power source; and

(ii) a header, at least a portion of which protrudes through the ballast housing, the header electrically associated with the internal circuitry;

wherein the header comprises one or more connection points, the connection points accessible from outside the ballast housing and for electrically connecting one or more external wires to the internal circuitry; and

(b) electrically connecting wires of the fluorescent light fixture to the header of the emergency lighting ballast.

18. The method of installing an emergency lighting ballast in a fluorescent light fixture of claim 17, wherein electrically connecting wires of the fluorescent light fixture to the header of the emergency lighting ballast further comprises connecting the wires of the fluorescent light fixture to an external connector and connecting the external connector to the header of the emergency lighting ballast.

19. The method of installing an emergency lighting ballast in a fluorescent light fixture of claim 18, further comprising:

(a) disconnecting the external connector from the header of the emergency lighting ballast;

(b) removing the emergency lighting ballast from the fluorescent lighting fixture;

(c) locating and securing a second emergency lighting ballast in the fluorescent lighting fixture; and

(d) electrically connecting wires of the fluorescent light fixture to the header of the second emergency lighting ballast.

20. The method of installing an emergency lighting ballast in a fluorescent light fixture of claim 17 further comprising:

electrically connecting a pilot light and test switch to the header of the emergency lighting ballast.
