A load regulation device for controlling the amount of power delivered to an electrical load may be able to calibrate the magnitude of an output voltage of the load regulation device in order to control the magnitude of a load voltage across the electrical load to a predetermined level. The load regulation device may receive the feedback from a calibration device adapted to be coupled to load wiring near the electrical load. The feedback may indicate when the magnitude of the load voltage across the electrical load has reached a predetermined level. The load regulation device may gradually adjust the magnitude of the output voltage, receive the feedback from the calibration device, and then use the feedback to determine the magnitude of the output voltage corresponding to when the magnitude of the load voltage across the electrical load has reached the predetermined level.

Calibration of a load control device for a light-emitting diode light source

A load regulation device, such as an LED driver, may be configured to control the intensity of a light source based on an analog control signal and a preconfigured dimming curve. The LED driver may sense a magnitude of the analog control signal and determine a new low-end and/or high-end control signal magnitude that falls outside of the input signal range of the dimming curve. The LED driver may rescale the preconfigured dimming curve according to new low-end and/or high-end control signal magnitudes and dim the light source based on the rescaled dimming curve. Multiple LED drivers controlled by the same analog control signal may communicate with each other regarding the magnitude of the analog control signal sensed by each LED driver, and match their target intensity levels despite sensing different analog control signal. A controller may be provided to coordinate the operation of the multiple LED drivers.

Configuration for a load regulation device for lighting control

A linear lighting fixture may comprise lighting control devices for controlling lighting loads in a load control system. Each linear lighting fixture may include a fixture controller configured to control lighting control devices. The fixture controller may receive messages from one or more devices in the load control system for controlling lighting control devices in the linear lighting fixture. The fixture controller may receive the message and communicate with the lighting control devices on a wired power/communication link. Each linear lighting fixture may comprise one or more sensors. The sensors may be coupled to the fixture controller to send/receive messages on a wired power/communication link and/or a wireless communication link. The lighting control devices in the fixtures may be zoned separately or together. Each of the sensors in a linear lighting fixture may be zoned with one or more of the lighting control devices in the linear lighting fixture.
