Abstract
A control device may be configured to control an amount of power delivered to one or more electrical loads and provide various feedback associated with the control device and/or the electrical loads. The control device may be a wall-mounted device or a battery-powered remote control device. The feedback may indicate the amount of power delivered to the one or more electrical loads. The feedback may also indicate a low battery condition. The control device may include a light bar and/or one or more indicator lights for providing the feedback.
Claims20
A control device for controlling an electrical load in a load control system, the control device comprising:
- a rotating portion;
- a light bar configured to be illuminated by a plurality of light sources arranged in a complete or partial loop;
- and
- a control circuit configured to generate a control signal for adjusting an amount of power delivered to the electrical load in response to a rotational movement of the rotating portion, the control circuit further configured to illuminate at least a subset of the light sources to indicate the amount of power delivered to the electrical load, wherein the illuminated light sources create one or more illuminated portions on the light bar, and wherein the control circuit is configured to adjust the subset of the light sources that are illuminated based on the rotational movement of the rotating portion such that the one or more illuminated portions of the light bar expand and contract in response to the rotational movement of the rotating portion;
- wherein the control circuit is further configured to control the light sources that are illuminated such that, when the rotating portion is being rotated, at least one end point of the one or more illuminated portions move along the light bar at a different angular speed than that of the rotating portion.
