An irradiation control region of a headlight (3) including a first region (R1) including a vehicle (V) in front of the vehicle and a second region (R2) not including a front vehicle in a periphery of the first region is set, based on a front captured image...

A vehicular power source controller (1) is designed so that when there is abnormal action in a microprocessor (11) and an abnormal fuse state cannot be determined from the current of a load (5) detected by a current sensor circuit (15), power supply to the...

A state where an engine is in an idling state, a dynamo (21) supplies electric power to a starting device (71), a headlight (39), a taillight (51) and an ECU (33), and the battery (35) is disconnected from power source wiring (76) and a ground circuit (77)...

A lighting element (100) comprising at least two OLEDs (20) as light sources, a motor vehicle light (01) equipped with at least one such lighting element (100), and a method for operating at least one such lighting element (100) and/or a motor vehicle ligh...

A vehicle lamp includes a light source (2), a solenoid-type actuator (6), and a lamp control device (LC). The light source (2) lights up when a current flows therethrough. The actuator (6) controls a light distribution of light that is illuminated from the...

A vehicle lighting unit (10) can reduce the load applied to the actuator (31, 32, 51, 52) for driving a reflecting member (2) as well as can improve the durability of the actuator (31, 32, 51, 52). The vehicle lighting unit (10) can include a light source,...

The method involves detecting a duty cycle of a lighting device (14-17, 210) according to switching-on of the lighting device. The estimated temperature of the lighting device is computed based on the duty cycle of the lighting device. The supply of curren...

A vehicle lighting unit (10) can reduce the load applied to the actuator (31, 32, 51, 52) for driving a reflecting member (2) as well as can improve the durability of the actuator (31, 32, 51, 52). The vehicle lighting unit (10) can include a light source,...

The method involves modulating electrical power level delivered by an electrical power source (PS) according to distinct power levels (Pi) with relation to function associated with an LED assembly (G1). The distinct electrical power levels are temporarily ...
