MECHANISMS FOR LIGHT MANAGEMENT

摘要

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.

1. An apparatus for a light emitting diode light bulb, comprising:
a plurality of light emitting diodes connected to a base, the plurality of light emitting diodes providing illumination in the light emitting diode light bulb; and a module which detects a residual voltage of an electrical power source when a control for powering the light emitting diode light bulb is powered off, the residual voltage detected when a path to a hot wire is open from the electrical power source; wherein 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, when the path to the hot wire is open from the electrical power source; wherein the module determines that a power outage occurred and switches to battery power from a battery in response to detecting no presence of the residual voltage of the electrical power source.
