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.

The microprism layer is optically connected to the matrix of solid state light emitters. A plurality of light direction controlling structures in the microprism layer can each control the direction of the light emitted from the solid state emitters and/or their lumen output levels from the lamp. Controller circuitry is provided to control solid state light emitters and/or the controllable elements of microprism layer.
