Lighting control having an idle state with wake-up upon actuation
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 bidirectional semiconductor switch operable to be coupled in series electrical connection between the source and the load, the semiconductor switch having a control input;
a controller operatively coupled to the control input of the semiconductor switch for controlling the amount of power delivered to the load;
an actuator operatively coupled to the controller such that the controller is operable to determine a desired amount of power to be delivered to the load in response to actuations of the actuator; and
a visual display responsive to the controller;
wherein the controller is operable to illuminate the visual display to a first intensity upon actuation of the actuator and to subsequently illuminate the visual display to a second intensity less than the first intensity after a predetermined amount of time has elapsed since the actuation of the actuator.

18. A method of displaying feedback on a plurality of status indicators of a load control device, the load control device operable to control the amount of power delivered from an AC power source to an electrical load, the method comprising the steps of:
-
pressing an actuator; subsequently releasing the actuator; illuminating the status indicators to a first intensity in response to the step of pressing the actuator; and illuminating the status indicators to a second intensity less than the first intensity after a predetermined amount of time has elapsed since the step of releasing the actuator. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
