Abstract
In embodiments of the present invention improved capabilities are described for systems and methods that employ a control component and/or power source integrated in an LED based light source to control and/or power the LED light source wirelessly. In embodiments, the LED based light source may take the form of a standard light bulb that plugs into a standard lighting socket or fixture.
Claims23
-20. (canceled)
A lighting control apparatus comprising:
- a housing;
- a switch associated with the housing and having an input configured to receive power from a primary source of power;
- an energy storage device disposed within the housing;
- power converter circuitry configured to convert power from the energy storage device;
- a lighting circuit input associated with the housing and configured to receive power for illuminating at least one light source;
- and
- a controller configured to:
- determine whether power from the primary source of power is available at the input of the switch;
- and
- cause application of power from the energy storage device to the lighting circuit input only if power from the primary source of power is not available at the input of the switch.

A wall switch module comprising:
- a retrofit housing;
- a switch associated with the retrofit housing and having an input configured to receive power from a primary source of power;
- an energy storage device disposed within the retrofit housing;
- power converter circuitry configured to convert power from the energy storage device;
- a lighting circuit input associated with the retrofit housing and configured to receive power for illuminating at least one light source;
- and
- a controller configured to:
- determine whether power from the primary source of power is available at the input of the switch;
- and
- cause application of power from the energy storage device to the lighting circuit input only if power from the primary source of power is not available at the input of the switch.

A lighting control apparatus comprising:
- a housing;
- a switch associated with the housing and having an input configured to receive power from a primary source of power;
- a mode selector;
- an energy storage device disposed within the housing;
- a lighting circuit input associated with the housing and configured to receive power for illuminating at least one light source;
- and
- a controller configured to:
- determine whether power from the primary source of power is available at the input of the switch;
- determine an operational state of the switch;
- determine a state of the mode selector;
- and
- cause application of power from the energy storage device to the lighting circuit input based on whether power from the primary source of power is available at the input of the switch, the operational state of the switch, and the state of the mode selector.
