Abstract
A backup lighting apparatus includes a light housing having a conductive base selectively connected to a light socket and a bulb portion extending upwardly therefrom that defines an interior area. A processor, battery, light, and audio sensor are situated in the interior area. The audio sensor is configured to detect a predetermined sound. Another sensor in the interior area is configured to detect a power outage and if a light switch is in an “on configuration.” The processor causes the battery to energize the light if a power outage is detected, the light switch is “on,” and a predetermined sound—such a hand clap—is detected. Accordingly, only a room in which a light was already on when an outage occurred and in which a person is present and signals for a backup is illuminated, such that electricity and battery power is conserved.
