Publication number: 20250203740Abstract: The present invention discloses a lighting system with illumination range adjustment function based on radio frequency signal control, which includes a radio frequency control module, first light-emitting module and second light-emitting module. The radio frequency control module is disposed at a central point and generates a radio frequency control signal. The first light-emitting module receives the radio frequency control signal. A first reference circle passes through the first light-emitting module, and the center thereof coincides with the central point. The second light-emitting module receives the radio frequency control signal. A second reference circle passes through the second light-emitting module, and the center thereof coincides with the central point. The first light-emitting module is activated when the signal strength of the radio frequency control signal exceeds a threshold value.Type: ApplicationFiled: November 1, 2024Publication date: June 19, 2025Applicant: Xiamen PVTECH Co., Ltd.Inventors: FUXING LU, RONGHUI WANG

Patent number: 12129610Abstract: A combined plate-beam unit analysis method considering a residual stress effect of an orthotropic plate, which is used for analyzing an orthotropic steel bridge deck welded by a top plate of a bridge deck and a trapezoidal rib, the top plate of the bridge deck is analyzed by a flat shell unit, while each sub-plate forming a trapezoidal rib is analyzed by a plate-beam unit. The welding residual stress of a top plate and a trapezoidal rib is obtained by a residual stress self-balancing condition, and the initial deformation of a top plate and left and right web plates of a trapezoidal rib is obtained by the stress-strain relationship. The combined plate-beam unit analysis method has the advantages of less freedom and high calculation accuracy, so it is especially suitable for structural analysis of the trapezoidal rib orthotropic plates.Type: GrantFiled: June 23, 2021Date of Patent: October 29, 2024Assignee: South China University of TechnologyInventors: Niujing Ma, Ronghui Wang, Long Piao

Publication number: 20240334576Abstract: An illuminance calibration device includes a processing module and a light detecting module. The processing module executes an illuminance calibration process. The light detecting module detects the current illuminance of a target position and transmits the current illuminance to the processing module. When the processing module is executing the illuminance calibration process, the processing module transmits a test signal to a lighting device to adjust the brightness of the lighting device by the minimal brightness adjusting unit of the lighting device so as to obtain the adjusted current illuminance of the target position. Then, the processing module generates a brightness adjusting signal according to the current illuminance, the adjusted current illuminance, the minimal brightness adjusting unit and a target illuminance in order to adjust the brightness of the lighting device, such that the illuminance of the target position reaches the target illuminance.Type: ApplicationFiled: September 11, 2023Publication date: October 3, 2024Applicant: Xiamen PVTECH Co., Ltd.Inventors: FUXING LU, RONGHUI WANG
