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.

摘要： A headlight device includes an optical unit to emit light and a support mechanism to support the optical unit. The optical unit includes supported pins as a first supported part and supported groove parts as a second supported part. The support mechanism includes support groove parts as a first support part that is provided on a first straight line in a predetermined first direction and contacts the supported pins and support pins as a second support part that is provided on a second straight line in a second direction orthogonal to the first direction and contacts the supported groove parts. The support mechanism supports the optical unit to be freely rotatable around the first straight line passing through the support groove parts and freely rotatable around the second straight line passing through the support pins.

摘要： A headlight module includes: a light source for emitting light; a condensing optical element for concentrating the light; and an optical element including an incident surface for receiving the concentrated light, a reflecting surface for reflecting the received light, and an emitting surface for emitting the reflected light. The condensing optical element changes a divergence angle of the light to form a light distribution pattern. The reflected light and light that enters the optical element and is not reflected by the reflecting surface are superposed on a plane including a point located at a focal position of the emitting surface in a direction of an optical axis of the emitting surface and being perpendicular to the optical axis, thereby forming a high luminous intensity region in the light distribution pattern on the plane. The emitting surface has positive refractive power and projects the light distribution pattern formed on the plane.

摘要： 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.
