Lighting control with integral dimming
First Claim
1. A lighting fixture control system, comprising:
- a control station configured to communicate with a plurality of fixture control devices located remotely from the control station, to receive a dimming command for at least one of the fixture control devices via a user interface, and to send a dimming setting command to the at least one of the fixture control devices based at least in part on the received dimming command;
a fixture control device that is associated with a lighting fixture, located remotely from the control station, and configured to dim the lighting fixture via a variable dimming control signal based at least in part on the dimming setting command and a Wattage measurement received from the lighting fixture.

Abstract
Lighting control devices, network systems, and methodologies, including methods for providing closed-loop dimming control of such systems, are described. In some examples, disclosed methods and device configurations may include an intelligent photo control configured to accept target dimmed fixture wattage value commands from a user, and provide closed-loop control at the fixture to achieve that target wattage via real-time adjustment of the 0-10V dimming control signal sent to the LED driver. As such, the need for trial-and-error adjustments of the 0-10V analog control voltage, or derivation of dim voltage to fixture wattage response curves in order to achieve a desired fixture wattage level, may be reduced or eliminated.

3. A lighting fixture control apparatus, comprising:
-
a command-receiving module configured to receive a dimming setting command from a remote command center; a dimming controller module; and a fixture power measurement module, wherein the dimming controller module is configured to determine a target Wattage value based at least in part on the dimming setting command, and to iteratively adjust a dimming control signal based at least on part on a fixture Wattage measurement provided by the fixture power measurement module until the fixture Wattage measurement is within a predetermined range of the target Wattage value. - View Dependent Claims (4, 5, 6, 7, 8, 9)

10. A lighting fixture control system, comprising:
-
a processor; a communication device; memory including computer-executable instruction that configure the processor to perform operations including; receiving a network identifier for a remote lighting control module associated with a lighting fixture; registering the lighting control module with the lighting fixture control system; determining whether at least one of the lighting control module or the lighting fixture supports a dimming function; enabling a dimming option in a user interface based on a determination that the at least one of the lighting control module or the lighting fixture supports a dimming function; receiving a dimming input control via the user interface; and providing a dimming setting signal to the lighting control module based at least in part on the received dimming input control. - View Dependent Claims (11, 12)
