Publication number: 20240113501Abstract: An optoelectrical assembly includes a voltage conversion circuit, an optoelectrical semiconductor device, an optoelectrical detection circuit, and a controller. The voltage conversion circuit provides a bias voltage to the optoelectrical semiconductor device, and adjusts, by changing the bias voltage, an output optical power. A differential resistance value (Rdiff) of the optoelectrical semiconductor device within a range of a target optical power satisfies 0.1 ohm (?)?Rdiff?50?, and the differential resistance value is a ratio of a voltage variation to a current variation corresponding to the voltage variation. The optoelectrical detection circuit detects the output optical power, and outputs a detection signal to the controller. The controller determines a control signal based on the detection signal, and outputs the control signal to the voltage conversion circuit, where the control signal is used to adjust the bias voltage.Type: ApplicationFiled: December 8, 2023Publication date: April 4, 2024Inventors: Zhiyuan Lin, Huan Chen, Gang Li, Xiaofan Wu, Xiaolu Song

Patent number: 9108566Abstract: A vehicle headlamp system includes a headlamp assembly having a light source and a beam pattern panel. The beam pattern panel includes one or more regions capable of changing between opaque and transparent light-transmission states to selectively allow light from the light source to pass through the panel. The panel may be an LCD panel with a plurality of liquid crystal elements arranged in an array with the ability to provide a plurality of different beam patterns. The beam pattern may be determined and changed in real time based on information received at a system processor about one or more vehicle and/or road conditions. The headlamp system can direct a projected light beam into a curve in the road ahead and/or automatically change the direction of the projected beam to avoid shining light directly at oncoming drivers.Type: GrantFiled: March 14, 2013Date of Patent: August 18, 2015Assignee: Federal-Mogul CorporationInventors: Jeffrey Simchak, Xiaolu Chen, John Dominick
