A variable light distribution type optical unit that changes a light distribution mode of a high beam depending on a surrounding state and a traveling state of a vehicle is disposed in a first vehicle head lamp on a passenger seat side, and a figure drawing optical unit capable of forming a desired figure on a road surface in front of the vehicle by emitted light is disposed at a position symmetrical to the variable light distribution type optical unit in a second vehicle head lamp on a driver seat side.

Abstract: When a pedestrian who is crossing a road or is about to cross a road is detected and it is determined that there is a risk of the own vehicle coming into contact with the pedestrian, a figure rendering forming optical unit provided in a housing of a head lamp emits a spot of light having a predetermined width and a predetermined length to a road surface ahead in a crossing direction including the pedestrian or the like. Accordingly, the pedestrian or the like knows the presence of an approaching vehicle and a driver knows the presence of the pedestrian or the like who is crossing a road or is about to cross a road.

Abstract: A pair of left and right vehicle headlights (1R, 1L) having a bilaterally symmetrical arrangement of optical units therein. A variable-light-distribution optical unit (ADB) is arranged inside the vehicle headlight (1R) on the passenger side and makes the high beam light distribution mode variable in accordance with the surroundings and travel state of the vehicle. A graphic drawing optical unit (RM) capable of forming a desired graphic on the road surface ahead of the vehicle, by using emitted light, is arranged at a position inside the vehicle front light (1L) on the driver side, said position corresponding to the arrangement position of the variable-light-distribution optical unit. As a result, distortion in graphics drawn on the road surface is suppressed and the impact of pitching can be reduced.

The lamp control unit controls the on/off of each of the plurality of LEDs. The lamp control unit controls each LED in the following manner. Specifically, the luminance is gradually lowered in a first period when the luminance is lowered to a level at which the LED remains on at reduced luminance. The luminance is gradually lowered in a second period, which is shorter than the first period, when the luminance is lowered to a level at which the LED is off.
