    摘要： A headlight device includes a first optical system and a second optical system. The first optical system emits first light in a predetermined emission direction. Part of an optical axis of the first optical system coincides with part of an optical axis of the second optical system in the emission direction. The second optical system includes a light receiver and a first optical part, and second light traveling in an incidence direction opposite to the emission direction is incident on the second optical system. The first optical part includes an aperture part that sets a diameter of the second light traveling toward the light receiver through the second optical system to be smaller than a diameter of the second light when entering the second optical system.

    摘要： A headlight device includes: a light source that emits light; a light guide element that receives the light emitted from the light source through an incident surface and guides the received light to emit the guided light from an emitting surface; and a radiation optical system that radiates the light emitted from the emitting surface ahead of a vehicle. The light guide element includes: a first light guide portion that extends from the incident surface to the emitting surface and guides the received light; and a second light guide portion that is in contact with the first light guide portion, extends from the incident surface to the emitting surface, and guides the received light. The first and second light guide portions have different refractive indexes. The light guide element is configured so that part of light entering the first light guide portion can enter the second light guide portion.

    摘要： A vehicle headlight device 100 according to the present invention includes a first lamp 92 that has a light source 211, an optical system 21, a rolling mechanism 50, and a control circuit 60. The optical system 21 includes a first wedge prism 30 and a second wedge prism 40 in which an incident ray from the light source 211 is deflected and projected. The rolling mechanism 50 rotates the first wedge prism 30 about a rotation axis. The control circuit 60 controls the rolling mechanism 50 so that the first wedge prism 30 is rotated in a direction opposite to a vehicle bank direction in accordance with a vehicle bank angle d. The first wedge prism 30 and the second wedge prism 40 are disposed so that their surfaces perpendicular to the rotation axis face each other. The first wedge prism 30 is disposed so that a wedge angle a1 directs in a road surface direction. The first wedge prism 30 is disposed so as to be rotatable about the rotation axis.
