Publication number: 20250063643Abstract: 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.Type: ApplicationFiled: November 8, 2024Publication date: February 20, 2025Applicant: Lutron Technology Company LLCInventors: Matthew Knauss, Christopher G.

Publication number: 20230209679Abstract: 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.Type: ApplicationFiled: February 27, 2023Publication date: June 29, 2023Applicant: Lutron Technology Company LLCInventors: Matthew Knauss, Matthew W.
