Publication number: 20230389149Abstract: The lighting device may be configured to perform black body curve fading. For example, the control circuit may be configured to control the drive circuit such that the light emitted by the lighting load is adjusted (e.g., faded) along a black body curve. The control circuit may be configured to determine whether to fade from an initial color to a destination color in a Correlated Color Temperature (CCT) chromaticity space or an XY chromaticity space. The control circuit may be configured to determine whether the initial color and/or the destination color are on the black body curve. When the initial color and the destination color are determined to be on the black body curve, the control circuit may be configured to control the drive circuit such that the light emitted by the lighting device is adjusted from the initial color to the destination color along the black body curve.Type: ApplicationFiled: August 14, 2023Publication date: November 30, 2023Applicant: Lutron Technology Company LLCInventors: Matthew R. Blakeley, Christopher M. Green, Peter MacLellan, Robert C. Newman, JR., Jaykrishna A. Shukla

Publication number: 20230232515Abstract: A load control device coupled between an AC power source and an electrical load may operate in a three-wire mode or a two-wire mode based on whether the load control device is connected to a neutral side of the AC power source. The load control device may further comprise first and second zero-cross detect circuits to be respectively used in the two-wire mode or the three-wire mode, and a neutral wire detect circuit configured to generate a neutral-wire detect signal indicating whether the load control device is connected to the neutral side of the AC power source. A control circuit of the load control device may determine whether the load control device should operate in the two-wire mode or in the three-wire mode in response to the neutral-wire detect signal.Type: ApplicationFiled: March 20, 2023Publication date: July 20, 2023Applicant: Lutron Technology Company LLCInventors: Mark A. Benning, Thomas W. Brenner, Quinn Brogan, Donald F. Hausman, JR., Peter MacLellan, Matthew Kyle Olsen, Matthew Pennock
