Abstract

A load control device may be configured to provide a user interface for controlling the intensity and/or color of one or more lighting loads. The user interface may include separate actuation members for setting the intensity and/or color of the lighting loads. The user interface may include one actuation member configured to operate in an intensity and/or color control mode. The control mode of the actuation member may be set via a button, a lever, a rotary switch, a rotary knob, etc. The user interface may include a touch sensitive element capable of sensing a user's touch and translate the touch into a control signal. Feedback may be provided on the user interface to indicate the type of control being adjusted and/or amount of control being applied to the lighting loads.

First claim

The invention claimed is:

1. A lighting load control apparatus, comprising:
a faceplate;
control circuitry;
a first actuator extending through the faceplate to provide a first input signal to the control circuitry, the first input signal to cause the control circuitry to cause a transition in a lighting load between an ON operating state and an OFF operating state;
a second actuator extending through the faceplate to provide a second input signal to the control circuitry, the second input signal to cause the control circuitry to cause a reversible, continuous, variation in the intensity of an illumination provided by the lighting load in proportion to an input provided to the second actuator; and
a third actuator extending through the faceplate to provide a third input signal to the control circuitry, the third input signal to cause the control circuitry to cause a reversible, continuous, variation in the color temperature of an illumination provided by the lighting load in proportion to an input provided to the third actuator.

2. The lighting load control apparatus of claim 1 wherein the first actuator comprises a toggle switch that extends through a first bezel.

3. The lighting load control apparatus of claim 2 wherein the second actuator comprises a first slider slot and first slider that extends through a second bezel.

4. The lighting load control apparatus of claim 3 wherein the third actuator comprises a second slider slot and second slider that extends through a third bezel.

5. The lighting load of claim 4 wherein the third bezel is formed orthogonal to the second bezel.

6. The lighting load of claim 4 wherein at least one of the first actuator, the second actuator, or the third actuator comprises a touch sensitive surface.

7. The lighting load of claim 1 , further comprising a plurality of indicators, the plurality of indicators illuminated in proportion to the input provided to the second actuator.

8. The lighting load of claim 1 , further comprising a plurality of indicators, the plurality of indicators illuminated in proportion to the input provided by the third actuator.

9. The lighting load control apparatus of claim 1 wherein the first actuator comprises a first slidable portion of a first slider switch that extends through a first bezel.

10. The lighting load control apparatus of claim 9 wherein the second actuator comprises a second slidable portion of the first slider switch that extends through the first bezel.

11. The lighting load control apparatus of claim 10 wherein the third actuator comprises a slider carried piggyback by the first slider switch.

12. The lighting load control apparatus of claim 3 wherein the third actuator comprises a rotatable knob that forms at least a portion of the first slider.

13. A lighting load control apparatus, comprising:
a faceplate;
a first bezel;
a slider slot formed in the first bezel, the slider slot including:
a first slot portion to provide a binary input signal to a control circuitry, the binary input signal to cause the control circuitry to cause a transition a lighting load between an ON operating state and an OFF operating state; and
a second slot portion to provide a variable input signal to the control circuitry;

a rotatable slider knob, the rotatable slider knob selectively rotatable between a first position and a second position;
wherein, responsive to detection of the rotatable slider knob in the first position, the variable input signal to cause the control circuitry to selectively cause a reversible, continuous, variation in the intensity of an illumination provided by the lighting load in proportion to a position of the rotatable slider knob in the second slot portion of the slider slot; and
wherein, responsive to detection of the rotatable slider knob in the second position, the variable input signal to cause the control circuitry to selectively cause a reversible, continuous, variation in the color temperature of an illumination provided by the lighting load in proportion to a position of the rotatable slider knob in the second slot portion of the slider slot.
