Abstract:
1. An apparatus for a light emitting diode light bulb, comprising: a plurality of light emitting diodes operative for illumination in the light emitting diode light bulb; a battery; a base that fits a socket designed for an incandescent light bulb, the base operatively connecting to an electrical power source; and a module operative to detect a residual voltage of the electrical power source when a control for powering the light emitting diode light bulb is powered off, the module detecting the residual voltage when a path to a hot wire is open in the electrical power source, wherein the module comprises and integrates hardware of a detection module and controller; wherein the module is operative to determine that a power outage occurred and operative to switch to battery power from the battery in response to detecting no presence of the residual voltage of the electrical power source; wherein when the path to the hot wire is open in the electrical power source, the module detects the residual voltage on a closed path with the light emitting diode light bulb that remains closed between a neutral wire and a ground wire, the residual voltage being approximately 7 volts.
