Power Failure Reporting in a Networked Light
First Claim
Patent Images
1. A method for reporting a state of a networked light bulb, the method comprising:
- storing energy in a networked lighting apparatus;
detecting that an external power source has stopped providing power to the networked lighting apparatus; and
sending a network message from the networked lighting apparatus in response to said detection that the external power source has stopped providing power to the networked lighting apparatus, said network message comprising data indicating that the networked lighting apparatus is entering an off state;
wherein said stored energy is sufficient to power at least a portion of the networked lighting apparatus for a period of time long enough to send said network message.

Abstract
Power is stored in a networked light allowing the networked light to send a message over the network providing information that the networked light is turning off if external power is no longer available.

7. A lighting apparatus comprising:
-
at least one light emitting element; a networked controller configured to communicate over a network and to control an on/off state of the at least one light emitting element; power conversion circuitry configured to receive power from an external power connection and provide power for the at least one light emitting element; an energy storage device configured to store energy from the power conversion circuitry; and power detection circuitry configured to send a power fail indication to the networked controller if the external power connection stops providing power to the lighting apparatus; wherein the networked controller is configured to send a message over the network in response to the power fail indication while being powered by the energy storage device, said network message indicating that the lighting apparatus is entering an off state. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A light bulb comprising:
-
at least one light emitting light emitting element; a networked controller configured to communicate over a network and to control an on/off state of the at least one light emitting element; power conversion circuitry configured to receive power from an external power connection through a base and provide power for the at least one light emitting element; an energy storage device configured to store power from the power conversion circuitry; power detection circuitry configured to send a power fail indication to the networked controller if the external power connection stops providing power to the lighting bulb; and a shell connected to the base and containing the at least one light emitting element, the networked controller, the power conversion circuitry, the energy storage device and the power detection circuitry, said shell at least partially transparent and substantially the same size and shape as a typical incandescent light bulb; wherein the networked controller is configured to send a message over the network in response to the power fail indication while being powered by the energy storage device, said network message indicating that the lighting bulb is entering an off state. - View Dependent Claims (15, 16, 17, 18, 19, 20)
