Abstract

A multiple-input power control system accepts control signals from a radiant signal transmitter and from a local control, selects one of the signals, and provides the selected signal to a power controller to control the power to a load. At least one of the control signal sources has an actuator which is movable through a range of positions, to determine the control signal provided by that source. The system finds particular utility in controlling lighting loads.

Claims

1. A wireless power control system with auxiliary local control comprising, in combination,

(a) transmitter means to transmit a radiant first control signal,

(b) receiver means to receive and store said first control signal,

(c) auxiliary local control means to provide a second control signal,

(d) decider means to select one of said first or second control signals and to provide said selected signal to power control means to control the power supplied from a source to a load over a substantially continuous range of values, wherein said transmitter means has actuator means manually movable through a continuous range of positions to produce said first control signal.

2. The system of claim 1 in which said auxiliary local control means has an actuator manually movable through a range of positions to produce said second control signal.

3. The system of claim 1 in which said auxiliary local control means produces control signals which serve only to increase and decrease the power supplied to the load.

4. The system of claim 1 in which said power control means controls a lighting load.

5. The system of claim 1 in which said power control means produces a phase controlled output signal.

6. The system of claim 1 in which said decider means comprises at least one latching relay.
