A vehicle which turns in a state in which a vehicle body is banked from an upright state to a first side in a vehicle width direction of the vehicle body, comprises a lamp which is attached to the vehicle body, and irradiates a lamp irradiation region set in front of the vehicle body; a detecting section which detects a change over time of a posture of the vehicle body while the vehicle is traveling; and a control section which controls the lamp in such a manner that the lamp irradiation region is changed based on the change over time of the posture of the vehicle body which is detected by the detecting section.

A vehicle headlight device 100 includes a light source 11, a Dove prism 40, and a rotation mechanism 50. The light source 11 emits light. The Dove prism 40 changes a propagation direction of light received at an incidence surface 401 to bring the light to a reflecting surface 402, and changes a propagation direction of light reflected at the reflecting surface 402 to output the light from an exit surface 403. The rotation mechanism 50 rotatably supports the Dove prism 40 about a line which passes through the incidence surface 401 and the exit surface 403 as an axis of rotation R, and rotates the Dove prism 40 in a direction opposite to a bank direction of a vehicle body in accordance with a bank angle k of the vehicle body.

A headlight device including a headlight configured to emit light frontward of a leaning vehicle to form a lower light beam, an upper central light beam, an upper left light beam and an upper right light beam, and a control device that controls light emission from the headlight without any user operation. The control device forms both the upper left and the upper right light beams while the leaning vehicle is traveling straight, and reduces a brightness of the upper left and upper right light beams, responsive to a vehicle being illuminated by the upper left and upper right light beams respectively, and forms the upper left and upper right light beams respectively while the leaning vehicle is turning left and right, and maintains the brightness of the formed upper left or upper right light beam regardless of whether any vehicle is illuminated by the upper left or upper right light beam.

An intelligent follow-up illumination device includes a support component, a rotating component, a driving component, a light source component, a projection component, a control component, and a casing. The support component is adapted to be installed on a vehicle in a fixed state. The rotating component is disposed to rotate relative to the support component. The driving component is disposed between the support component and the rotating component to drive the rotating component to perform a rotation operation around a rotation axis. The light source component is disposed inside the rotating component to emit illumination light. The projection component is retained on the rotating component to project the illumination light outwardly, so as to form a light distribution pattern. The control component is connected to the rotating component and adapted to send a control command to the driving component. The casing is disposed to enclose the control component.

A headlight system for a banking vehicle is provided. The headlight system includes a plurality of optical assemblies being arranged about an optical horizon and an optical vertical axis. Each of the plurality of optical assemblies includes an illumination source and an optical element. Each of the illumination sources is configured to direct light toward a corresponding one of the optical elements to produce an illumination region. The illumination regions combine to form an illumination pattern that includes at least one illumination region that is radial and is positioned relative an optical origin. The intersection between the optical horizon and the optical vertical axis defines the optical origin.

A headlight device includes a headlight and a control device. The headlight includes a plurality of light sources that is configured to light one or more left oblique areas located in the ahead-driving direction of the leaning vehicle on the left, one or more right oblique areas located in the ahead-driving direction of the leaning vehicle on the right, and one or more lower areas located in the ahead-driving direction of the leaning vehicle. The control device controls the headlight to light at least the left oblique areas and the right oblique areas based on adaptive lighting control. At least one of the left oblique areas and at least one of the right oblique areas that are lit based on the adaptive lighting control spread more outwardly in a left-right direction than any of the lower areas.

A control device of a leaning vehicle for controlling bright lighting and dim lighting for a plurality of oblique areas. When the leaning vehicle is upright, the control device controls the lighting by designating one or more of the plurality of oblique areas as in a brightly lit area to which adaptive lighting control is applied, and by designating the other oblique areas as in a dim area. The dim area includes an uppermost oblique area. When the leaning vehicle turns left or right, as a lean angle in a direction of the turn increases, the control device controls the lighting by designating a second uppermost oblique area that is located immediately below the uppermost oblique area in the up-down direction as in the brightly lit area, and moving the uppermost oblique area from the dim area to the brightly lit area.
