Abstract

A low profile combination exit and emergency light system having a single piece body with a central internal chamber having a pair of spaced batteries connected to a LED lighting strip, and a pair of integral end portions with separate downwardly shining lights held therein. The system may be mounted from the top utilizing a special adapter and may include emergency lights mounted in special movable housings that pivot to allow a broad range of motion.

Claims

1. A combination lighted exit sign and emergency lighting system, comprising:

a one piece body having an enlarged central portion and a pair of smaller end portions fixedly secured to the enlarged central portion;

the enlarged central portion being hollow and containing a spaced apart pair of batteries electrically connected to a transformer and an LED lighting strip;

a front cover plate and a rear cover plate for the enlarged central portion, with indicia formed in at least the front cover;

a pair of emergency lights secured in the pair of smaller end portions and electrically connected to the pair of batteries; and

a pair of downwardly pointing lights held in bottom portions of the pair of smaller end portions for shining light downwardly, away from a top surface toward a floor.

2. The combination lighted exit sign and emergency lighting system of claim 1 wherein the pair of emergency lights are movably held in bases secured in the pair of smaller end portions.

3. The combination lighted exit sign and emergency lighting system of claim 2 wherein the one piece body is substantially narrow and the pair of smaller end portions include separate rear covers removably attached thereto.

4. The combination lighted exit sign and emergency lighting system of claim 3 wherein the bases include pivoting means held in separate housings secured in shallow dish type portions formed in the pair of smaller end portions.

5. The combination lighted exit sign and emergency lighting system of claim 4 wherein the pair of emergency lights have a rectangular shape.

6. The combination lighted exit sign and emergency lighting system of claim 4 wherein the pair of emergency lights are circular in cross-section.

7. A combination lighted exit sign and emergency lighting system, comprising:

a one piece substantially narrow body having an enlarged central portion and a pair of smaller end portions integrally and fixedly formed with the enlarged central portion;

the enlarged central portion having a hollow chamber formed therein containing a pair of spaced apart batteries supported adjacent the pair of smaller end portions and electrically connected to a transformer and a single LED lighting strip;

a front cover plate and a rear cover plate removably attached to the enlarged central portion, with indicia formed in at least the front plate;

a pair of emergency lights secured in the pair of smaller end portions and electrically connected to the pair of spaced apart batteries; and

a pair of downwardly pointing lights held in bottom portions of the pair of smaller end portions for shining light downwardly, away from a top surface toward a doorway.

8. The combination lighted exit sign and emergency lighting system of claim 7 wherein the pair of emergency lights are movably held in bases removably secured in the pair of smaller end portions.

9. The combination lighted exit sign and emergency lighting system of claim 8 wherein the pair of emergency lights have a rectangular shape.

10. The combination lighted exit sign and emergency lighting system of claim 9 wherein the pair of smaller end portions include separate rear covers removably attached thereto and the bases include pivoting means held in separate housings secured in shallow dish type portions formed in the pair of smaller end portions.

11. The combination lighted exit sign and emergency lighting system of claim 10 wherein the pair of emergency lights are circular in cross section and include guide means held in slots formed in the bases.

12. The combination lighted exit sign and emergency lighting system of claim 7 wherein the bases include pivoting means held in separate housings secured in shallow dish type portions formed in the pair of smaller end portions and the pivoting means includes a pair of toothed wheels.

13. A combination lighted exit sign and emergency lighting system, comprising:

a one piece substantially narrow body having an enlarged substantially rectangular shaped central portion and a pair of smaller end portions integrally and fixedly formed with the enlarged rectangular shaped central portion;

the enlarged rectangular shaped central portion having a hollow chamber formed therein containing a pair of spaced apart batteries supported adjacent the pair of smaller end portions and electrically connected to a transformer and a single LED lighting strip having a plurality of lamps therein;

a substantially rectangular shaped front cover plate and a substantially rectangular shaped rear cover plate removably attached to the enlarged substantially rectangular shaped central portion, with indicia formed in at least the front cover plate;

a pair of circular shaped emergency lights secured in the pair of smaller end portions and electrically connected to the pair of spaced apart batteries;

the pair of circular shaped emergency lights being movably held in bases removably secured in the pair of smaller end portions; and

a pair of downwardly pointing lights held in bottom portions of the pair of smaller end portions for shining light downwardly, away from a top surface toward a doorway.

14. The combination lighted exit sign and emergency lighting system of claim 13 wherein the pair of downwardly pointing lights are intense enough to shine through haze or smoke to light a doorway.

15. The combination lighted exit sign and emergency lighting system of claim 13 wherein the one piece substantially narrow body substantially eliminates light leakage from the body.
