Smart load control device having a rotary actuator
First Claim
1. A load control device for controlling the amount of power delivered from an AC power source to an electrical load, the load control device comprising:
- a controllably conductive device adapted to be coupled in series electrical connection between the AC power source and the electrical load for controlling the amount of power delivered to the load;
a controller coupled to a control input of the controllably conductive device, the controller operable to selectively render the controllably conductive device conductive and non-conductive to control the amount of power delivered to the load;
a rotary actuator operable to rotate in a first direction and a second direction, the controller responsive to rotations of the rotary actuator to adjust the amount of power delivered to the load when the rotary actuator is rotated; and
an audible sound generator responsive to the controller, the controller operable to cause the audible sound generator to repeatedly generate an audible sound when the lamp control module is delivering a predetermined amount of power to the load and the rotary actuator is rotated.

Abstract
A load control device for controlling the amount of power delivered from an AC power source to an electrical load comprises a rotary actuator, such as a rotary knob or a rotary wheel. The load control device increases and decreases the amount of power delivered to the electrical load in response to rotations of the rotary knob in first and second directions, respectively. The load control device accelerates the rate of change of the amount of power delivered to the load in response to the angular velocity of the rotary actuator. The load control device generates a ratcheting sound when the rotary actuator is rotated in the first direction at a high-end intensity of the load control device. The load control device is operable to control the electrical load in response to both actuations of the rotary actuator and digital messages received via a communication link.
