Abstract
The present invention provides a housing for an emergency light source which is electrically connectable to a conventional light switch. The housing replaces a conventional switch plate and has at least one opening for receiving the switch actuator of the light switch. The replacement housing includes wires for electrical connection to the light switch and is divided into upper and lower housing sections, wherein the upper section includes a battery compartment, a printed circuit board compartment, and an opening to receive the switch actuator. The lower housing section includes a compartment for receiving a compact fluorescent lamp, reflectors, and a diffuser cover. The printed circuit board includes a recharger for the batteries; a power-sensing device for sensing power interruption; an ON/OFF relay switch which is turned on in response to a power failure and actuates the emergency light source; a LED charging indicator light to show that the batteries are charging; a manual test switch; and a transformer, a fluorescent ballast, and starter components for the fluorescent lamp.
