摘要： The invention provides an automotive luminous device (10) for an automotive vehicle (100). It comprises a buck converter (1) configured to produce a voltage value in the voltage output (5) which is lower than the voltage value received at the voltage input (4). The buck converter (1) is also configured so that the voltage value at the voltage output (5) depends on the voltage value received at the control input (6). It also comprises a temperature compensation circuit (2) comprising a thermistor, the temperature compensation circuit having a circuit input (7) receiving the voltage output from the buck converter (1) and having a circuit output (8) connected to the control input (6) of the buck converter (1). Finally, it also comprises at least one light branch (3) connected in parallel between the voltage output and the ground connection, each light branch comprising at least one solid-state light source (9) and at least one passive component, such as a resistor (12), mounted in series with the at least one solid-state light source (9).

摘要： A vehicle headlight (1) includes: a second light source unit (40) that includes second light emitting units (43); an actuator (50) that adjusts a direction of light emitted from the second light source unit (40); and a controller (CO), in which the controller (CO) switches the second light emitting unit (43) that emits the light having the highest intensity to another second light emitting unit (43), and controls the actuator (50) to change a direction of second light emitted from the second light source unit (40) in such a way that a region (110) where the intensity of the light is highest in a light distribution pattern (103) after the switching approaches a region (110) where the intensity of the light is highest in the light distribution pattern (103) before the switching.
