Headlight device and leaning vehicle

A headlight device to be employed in a leaning vehicle that has a vehicle body leaning leftward when turning left and leaning rightward when turning right, the headlight device comprising:

• a headlight including a plurality of light sources, which is configured to respectively light a plurality of areas that include:
• a plurality of left oblique areas that are located in an ahead-driving direction, and on the left, with respect to the headlight of the leaning vehicle, the plurality of left oblique areas each having a maximum luminous intensity point thereof above a horizontal reference line,
• a plurality of right oblique areas that are located in the ahead-driving direction, and on the right, with respect to the headlight of the leaning vehicle, the plurality of right oblique areas each having a maximum luminous intensity point thereof above the horizontal reference line, and
• one or more lower areas that are located in the ahead-driving direction with respect to the headlight of the leaning vehicle, the one or more lower areas each having a maximum luminous intensity point thereof below the horizontal reference line;
• and
• a control device that controls the headlight to light at least the plurality of left oblique areas and the plurality of right oblique areas based on adaptive lighting control, such that when an oncoming vehicle or a vehicle ahead is in one of the areas lit by the headlight, the light for the one area is reduced or turned off, wherein:
• the plurality of left oblique areas are located at different heights in an up-down direction, and among the plurality of left oblique areas, one that is higher spreads more outwardly in the left-right direction than another one therebelow,
• the plurality of right oblique areas are located at different heights in the up-down direction, and among the plurality of right oblique areas, one that is higher spreads more outwardly in the left-right direction than another one therebelow,
• when the leaning vehicle is upright, the control device instructs the headlight to light at least one of the plurality of left oblique areas, at least one of the plurality of right oblique areas, and at least one of the one or more lower areas, each of said at least one left oblique area and said at least one right oblique area being lit based on the adaptive lighting control and spreading more outwardly in a left-right direction than any of said at least one lower area, and
• wherein when the leaning vehicle is upright, the horizontal reference line extends in the left-right direction through an upper edge of a low-beam area, the low-beam area being one of the one or more lower areas that is at a center with respect to the left-right direction.
