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: 20250063647Abstract: A load control system may include load control devices for controlling power provided to an electrical load. The load control devices may include a control-source device and a control-target device. The control-target device may control the power provided to the electrical load based on digital messages received from the control-source device. A user device may discover load control devices when the load control devices are within an established range associated with the user device. The user device and the load control devices may communicate via a wireless communications module. The established range may be adjusted based on the configurable transmit power of the user device or the wireless communications module associated with the user device. A discovered control-target device may be associated with a control-source device to enable the control-target device to control the power provided to the electrical load based on digital messages received from the control-source device.Type: ApplicationFiled: November 7, 2024Publication date: February 20, 2025Applicant: Lutron Technology Company LLCInventors: Jordan H.

Publication number: 20250059828Abstract: A sensor and/or system controller may process an image multiple times at multiple resolutions to detect glare conditions. A glare condition threshold used to determine whether a glare condition exists may be based on the resolution of the image. When the resolution of the image is higher, the glare condition threshold may be higher. The sensor and/or system controller may organize one or more adjacent pixels having similar intensities into pixel groups. The pixel groups may vary in size and/or shape. The sensor and/or system controller may determine a representative group luminance for the pixel group (e.g., an average luminance of the pixels in the group). The sensor and/or system controller may determine a group glare condition threshold, which may be used to determine whether a glare condition exists for the group of pixels and/or may be based on the size of the group.Type: ApplicationFiled: November 6, 2024Publication date: February 20, 2025Applicant: Lutron Technology Company LLCInventors: Craig Alan Casey, Yogesh Venkata Gopalan, Brent Protzman

Publication number: 20250062955Abstract: A load control system may be commissioned using beacons. The load control system may include control devices that each include a beacon transmitting circuit configured to transmit a beacon that comprises an identifier associated with the control device. A network device, such as a mobile device, may discover a control device based on the beacon received from the control device. In response to discovery of the control device, the control device may be added to a temporary group of control devices for being collectively configured and/or controlled. Control devices may be discovered based on the signal strength at which the beacons are received. The control devices may provide feedback to a user in response to confirmation messages to indicate to a user that the lighting control device has been added to the temporary group. The control devices may stop providing the feedback after they are removed from the temporary group.Type: ApplicationFiled: October 31, 2024Publication date: February 20, 2025Applicant: Lutron Technology Company LLCInventors: Todd G.

Patent number: 12232228Abstract: A lighting device, such as a light-emitting diode (LED) light source, may operate in an interim operable state to avoid and/or prevent undesirable characteristics in the light emitted by the lighting device (e.g., strobing and/or flickering of a brightness of the light and/or shifting or change of a color of the light). When operating in a normal state, the control circuit may determine if a measured value of a first operational characteristic (e.g., a forward voltage of an emitter of the lighting device) is outside of a range and operate in the interim operable state if the measured value of the first operational characteristic is outside of the range. When operating in the interim operable state, the control circuit may adjust a drive current for the emitter in response to a measured value of a second operational characteristic (e.g., a forward voltage of a detector of the lighting device).Type: GrantFiled: November 29, 2023Date of Patent: February 18, 2025Assignee: Lutron Technology Company LLCInventors: Jason E.
