ABSTRACT:
An electronic layout of an electronic exit sign, that encompasses the entire electronic packaging and lighting inside the exit sign enclosure. The layout includes brackets that function both as a method for holding LEDs for illuminating the sign, and as enclosures for enclosing the electronics of a controller and a power unit. The LEDs are mounted to the brackets and held by nylon buttons. A battery pack for battery backup and a battery backup self-test switch is mounted to a releasable plate. This allows the battery backup feature to be an option and also allows for easy replacement of discharged batteries. The LEDs are spaced in such a way as to provide uniform lighting to both the exit sign and a chevron symbol. The LEDs are positioned so that the same unit can drive either a single or double face exit.
