A vehicle lighting unit control device according to an aspect of the present disclosure includes a lighting unit control section controlling a lighting unit, a power supply section outputting electrical power to a fan device, and a power supply control section. The fan device includes a fan and a motor. The power supply control section includes a rotation information acquisition section and an output interruption section. If the fan locks, the output interruption section interrupts electrical power supplied from the power supply section to the fan device, before the fan device performs protective operation for interrupting electrical power supplied to the motor.

A lamp unit includes a reflecting device in which a micromirror array is selectively driven to selectively reflect incident light, the micromirror array being an array of micromirrors arranged in a matrix; a projection lens that projects the light selectively reflected by the reflecting device, forward in a light distribution pattern; and a restraining portion configured to restrain external light incident on the projection lens from being condensed in a region other than the micromirror array to restrain an increase in a temperature of the region.

An automotive electronic sensor assembly includes a light source configured to generate light into a field of view. A detector is configured to receive light reflected off an object in the field of view. The assembly also includes a temperature regulation system. The temperature regulation system includes a thermoelectric cooler coupled to the automotive electronic sensor assembly and a heat exchanger coupled to the thermoelectric cooler and including a passage for accommodating fluid from a cooling system of a vehicle.

In a lighting device adapted to be mounted on a vehicle, a PTC (positive temperature coefficient) thermistor (535), a first fixed resistor (R1), and a first light emitting element (531) are connected in series with a voltage source. A heat conduction suppressor (7) is configured to suppress heat conduction from the first fixed resistor (R1) to the PTC thermistor (535).
