US Patent:

20050264224, Dec 1, 2005

Filed:

Aug 2, 2005

Appl. No.:

11/195424

Inventors:

Peter Roach - Atlanta GA, US
Thomas Mayer - Wisconsin Dells WI, US
Pierce Roberts - Amelia Island FL, US

International Classification:

H05B039/00

US Classification:

315160000

Abstract:

Systems and methods are provided for deriving power for an external device from the power source of a fluorescent light. The power source includes a fluorescent ballast electrically connected to the connectors of a light fixture for receiving an input voltage and for converting the input voltage to a lamp voltage suitable for powering a fluorescent lamp. The fluorescent ballast may be modified to include an output line that outputs a voltage for powering the external device to a power port. The power port may be mounted on or near the fluorescent light. Alternatively, the power port may be integrated within a housing that contains one of the connectors of the light fixture. The ballast may be further modified to include an output line for extracting network data and control signals from the power line carrier signals on the input voltage.

Inventors:

Peter Roach - Atlanta GA, US

Pierce Roberts - Amelia Island FL, US

International Classification:

H05B039/00

US Classification:

315160000

Abstract:

Systems and methods are provided for deriving power for an external device from a circuit of a fluorescent light. A first circuit supplies power from a fluorescent light power source to a fluorescent lamp. The power converter of an external device can be electrically connected to any two points within that circuit to create a second circuit to supply power to the external device. The power converter may be connected to the first circuit via one or more power coupling or power tether. At least one of the two points within the first circuit may comprise a pin of the fluorescent lamp. Alternatively, at least one of the two points may comprise a connector of a fluorescent light fixture designed to receive a pin of the fluorescent lamp or a point within the fluorescent ballast of the fluorescent light fixture.

International Classification:

H05B037/00

Abstract:

Systems and methods are provided for deriving power for a wireless network component from the power source of a fluorescent light. Power couplings are electrically connected to the pins of a fluorescent lamp and to a power converter of the wireless network component so that a circuit is completed between the pins and the power converter. The power couplings may alternatively be electrically connected to the fluorescent lamp connectors of a fluorescent light fixture and to the power converter of the wireless network component to complete the circuit. Power supplied to fluorescent lamp is drawn by the circuit to power the wireless network component. Alternatively, the ballast of the fluorescent light power source may be modified to include an output line that outputs a voltage for powering the wireless network component to a power port. The power port may be mounted on or near the fluorescent light.
