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.

摘要： A headlight module includes a light source, a light distribution control element and a projection optical element. The light source emits light. The light distribution control element forms a light distribution pattern by changing a divergence angle of the light incident therein. The projection optical element projects the light distribution pattern. The light distribution control element includes a first light distribution formation part configured to form a high luminosity region in the light distribution pattern and a second light distribution formation part configured to form a low luminosity region in the light distribution pattern. The low luminosity region is lower in luminosity than the high luminosity region.

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.

Among the light converged on the incident surface (7) of the integrator rod (7), a converging angle of the light converged on a center portion of the incident surface (8) is smaller than a converging angle of the light converged on a corner portion of the incident surface (8).
