Abstract

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.
