Abstract

Mechanisms for light management include a light emitting diode (LED) light bulb. The LED light bulb includes multiple light emitting diodes (LEDs) configured for illumination in the LED light bulb and includes a battery. A base is configured to fit a standard socket designed for an incandescent light bulb, and the base is configured to operatively connect to an electrical power source. A module is operative to detect a residual voltage of the power source when a control for powering the LED light bulb is powered off. The module is configured to determine that a power outage occurred and operative to switch to battery power from the battery in response to not detecting the residual voltage of the power source.
