Abstract

A combination exit sign and emergency light is provided, wherein the emergency light is disposed along a bottom, portion of the exit sign. The bottom portion of the housing is formed with a recessed section intermediate opposing side flange portions, with a light bar incorporating LEDs being mounted in the recess section to provide emergency lighting during power outages and emergency situations. The bar is white in color on the outside, except a bottom portion of the bar is left clear for the free transmission of light. With this construction, at least a substantial majority of fight generated by the LEDs will be directed out of the bottom portion, while the side portions are also preferably lit thereby providing a more intense light out of the bottom portion to assure adequate illumination leading to a suitable exit.

Claims (31)

1. A combination exit sign and emergency light comprising:

a housing having a front face, opposing lateral sides and a bottom edge

portion defined by opposing side flange portions spaced by an intermediate, recessed section establishing an elongated cavity;

symbols provided on the front face adapted to be illuminated; and

a lighting system including a light bar mounted within the elongated cavity, said light bar including:

a main body having a top portion, side portions and a bottom portion, at least said bottom portion being transparent;

an elongated channel formed in the top portion; and

a strip of LEDs projecting into the channel wherein, during emergency situations, the LEDs are activated to direct light into the main body of the light bar, with at least a substantial majority of the light being directed out the bottom portion of the main body.

2. The combination exit sign and emergency light according to claim 1 , wherein the elongated channel extends across a majority of the main body.

3. The combination exit sign and emergency light according to claim 1 , further comprising: a PCB board mounted within the channel, with the LEDs being supported by and electrically connected to the PCB board.

4. The combination exit sign and emergency light according to claim 1 , further comprising: a transparent cover extending across the recessed section between the opposing side flanges.

5. The combination exit sign and emergency light according to claim 4 , wherein the cover is made of acrylic.

6. The combination exit sign and emergency light according to claim 4 , wherein the cover is snap-connected to the housing so as to be selectively removable.

7. The combination exit sign and emergency light according to claim 1 , further comprising: a colored coating provided on the side portions of the light bar, said colored coating enabling the side portions to be lit by the LEDs, yet assuring that a majority of light from the LEDs is directed out of the bottom portion.

8. The combination exit sign and emergency light according to claim 7 , wherein the coating extends from the top portion across the side portions, while leaving the bottom portion exposed.

9. The combination exit sign and emergency light according to claim 1 , wherein the light bar is constituted by a pipe or tube.

10. A combination exit sign and emergency light comprising:

a housing having a front face, opposing lateral sides and a bottom edge

portion defined by opposing side flange portions spaced by an intermediate, recessed section establishing an elongated cavity;

exit symbols provided on the front face adapted to be illuminated; and

a lighting system including a light bar mounted within the elongated cavity, said light bar including:

a main body in the form of a pipe or tube having a top portion, side portions and a bottom portion;

a strip of LEDs provided in the main body; and

a colored coating provided on the side portions of the main body but not on the bottom portion wherein, during emergency situations, the LEDs are activated to direct light into the main body of the light bar, with said colored coating enabling the side portions to be lit by the LEDs, yet assuring that a majority of light from the LEDs is directed out of the bottom portion.

11. The combination exit sign and emergency light according to claim 10 , wherein the LEDs are countersunk in the main body.

12. The combination exit sign and emergency light according to claim 10 , further comprising: a PCB board mounted within the main body, with the LEDs being supported by and electrically connected to the PCB board.

13. The combination exit sign and emergency light according to claim 10 , further comprising: a transparent cover extending across the recessed section between the opposing side flanges.

14. The combination exit sign and emergency light according to claim 13 , wherein the cover is made of acrylic.

15. The combination exit sign and emergency light according to claim 13 , wherein the cover is snap-connected to the housing so as to be selectively removable.

16. The combination exit sign and emergency light according to claim 10 , wherein the coating extends from the top portion across the side portions, while leaving the bottom portion exposed.

17. The combination exit sign and emergency light according to claim 10 , wherein the light bar is constituted by a pipe or tube.
