Patent ID: 8629618

Claim:
A backup lighting apparatus for use with a light socket that is electrically connected to an electricity source and to an actuation switch configured to move selectively between an “on configuration” that allows current from the electricity source to flow therethrough and an “off configuration” that prevents the current from the electricity source to flow therethrough, said backup lighting apparatus, comprising: a light housing having a conductive base configured to be conductively connected to the light socket and a bulb portion extending upwardly from said base that defines an interior area; a processor positioned in said interior area of the light housing bulb portion and electrically connected to said conductive base; a battery positioned in said interior area of the light housing bulb portion and electrically connected to said processor; a light positioned in said interior area of the light housing bulb portion and electrically connected to said processor; an audio sensor positioned in said interior area of the light housing bulb portion and electrically connected to said processor that is configured to detect a predetermined audio sound; a power sensor configured to determine if current is available from the electricity source and if the actuation switch is in the “on configuration.” programming that when executed by said processor determines if electrical current is available from the electricity source; programming that when executed by said processor determines if the actuation switch is in the “on configuration;” programming that when executed by said processor determines if a predetermined audible sound is received by said audio sensor; and programming that when executed by said processor causes said processor to actuate said battery to energize said light when said processor has determined that the actuation switch is in the “on configuration” and that current is not available from the electricity source and that said audio sensor has detected said predetermined audio sound.
