Power failure reporting in a networked light
First Claim
Patent Images
1. A lighting apparatus comprising:
- at least one light emitting element;
circuitry to detect a discontinuation of energy supplied from an external power connection;
a network interface to send a message over a network, indicating that the lighting apparatus is entering an off state, in response to the discontinuation of the energy supplied from the external power connection; and
an energy storage device to store energy from the external power connection and provide power to the network interface.

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.

1. A lighting apparatus comprising:
-
at least one light emitting element; circuitry to detect a discontinuation of energy supplied from an external power connection; a network interface to send a message over a network, indicating that the lighting apparatus is entering an off state, in response to the discontinuation of the energy supplied from the external power connection; and an energy storage device to store energy from the external power connection and provide power to the network interface. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A lighting system comprising:
-
a first networked device; and a second networked device comprising; at least one light emitting element; circuitry to detect a discontinuation of energy supplied from an external power connection; a network interface to send a status message, over a network, indicating that the lighting apparatus is entering an off state, in response to the discontinuation of the energy supplied from the external power connection; and an energy storage device to store energy from the external power connection and provide power to the network interface; wherein a state of the first networked device changes in response to the status message from the second networked device. - View Dependent Claims (9, 10, 11)

12. A method for controlling a networked device, 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; sending a network status message from the networked lighting apparatus in response to the detection that the external power source has stopped providing power to the networked lighting apparatus; and changing a state of the networked device in response to the network status message; wherein the stored energy is sufficient to power at least a portion of the networked lighting apparatus for a period of time long enough to send the network message. - View Dependent Claims (13, 14, 15, 16)
