Abstract

A system and method for emergency exit LED lighting. The emergency exit lighting fixture comprises a structure for housing at least one LED light, an LED driver electronically coupled to the LED light(s), a continuous power source, a backup power source, and a test switch. The fixture, in various configurations, may be mounted to a wall, a ceiling, or a doorway. The fixture may be tested remotely.

Claims

1. A ceiling mounted emergency exit lighting fixture comprising:

an elongate substantially rigid spine extending between a first bracket end and a second bracket end;

an elongate substantially rigid flat base substantially perpendicular to and coupled to said rigid spine and extending between the first bracket end and the second bracket end, having a substantially rectangular shape, a top plane, and a bottom plane;

at least one LED light mounted on said bottom plane;

an LED driver electronically coupled to a first power source, a backup battery containing enough power to power said at least one LED light for at least 90 minutes, said at least one LED light, and an on/off test switch; and

a translucent lens panel mounted to the bottom plane and adapted to diffuse light from said LED light;

wherein the fixture is mounted to a ceiling.

2. The ceiling mounted emergency exit lighting fixture of claim 1, wherein the first bracket end and the second bracket end are each adapted to be coupled to a ceiling T-grid.

3. The ceiling mounted emergency exit lighting fixture of claim 1, wherein the elongate substantially rigid flat base further comprises a first flange, a second flange, and a recessed channel between the first flange and the second flange.

4. The ceiling mounted emergency exit lighting fixture of claim 1, wherein the translucent lens comprises a cut-out, with a red or green color translucent lens panel placed within the cut-out.

5. The ceiling mounted emergency exit lighting fixture of claim 1, wherein the at least one LED light further comprises red or green LEDs.

6. The ceiling mounted emergency exit lighting fixture of claim 1, further comprising a wireless antenna electronically coupled to the on/off test switch and the LED driver.

7. The ceiling mounted emergency exit lighting fixture of claim 6, wherein said wireless antenna is adapted to receive a signal from a Wi-Fi connected smartphone application so as to activate the on/off test switch.
