A headlight module includes a light source, a light guide element, and a projection optical element. The light source emits light. The light guide element has a reflecting surface for reflecting light emitted from the light source and an emitting surface for emitting light reflected by the reflecting surface. The projection optical element projects light emitted from the emitting surface. In a direction of an optical axis of the projection optical element, an end portion on the emitting surface side of the reflecting surface includes a point located at a focal position of the projection optical element.

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.

A headlight module includes: a light source that emits light; a projection lens that receives and emits the light; a holder including a flexible portion having a length in a direction of an optical axis of the lens and having a fixed end and a movable end, the holder holding the lens movably relative to the light source by holding the lens with the movable end; and a driver that moves the lens. The lens is translated on a plane perpendicular to the axis due to deflection of the flexible portion. The holder includes first and second flexible portions including plate-like portions parallel to the axis and perpendicular to each other. One end of the first flexible portion is the fixed end. Another end of the first flexible portion is connected to one end of the second flexible portion. Another end of the second flexible portion is the movable end.

An adjustment mechanism configured to adjust a reference position of an optical axis of a projection lens of a lens unit has a reference axis perpendicular to the optical axis and disposed in a plane which intersects with a focal point of the projection lens. The lens unit moves in an extension direction of the reference axis in accordance with rotation of a second screw. An acting point of a force to move the lens unit is disposed in a plane formed by the optical axis and the reference axis.

A projection optical instrument includes a light source unit, a projection optical member and a support part. The light source unit emits light. The projection optical member transforms the light emitted from the light source unit into projection light. The support part supports the projection optical member to be movable with respect to the light source unit in at least one direction orthogonal to an optical axis direction of the light source unit. When vibration is applied to at least one of the light source unit and the projection optical member, the projection optical member accordingly vibrates with respect to the light source unit in a direction orthogonal to the optical axis direction of the light source unit.

A laser lamp module and a laser lamp system using the same, and more particularly, a laser lamp module capable of implementing a highlight zone and a shadow zone by selectively positioning a plurality of beam splitters in a path to which a beam is emitted from a laser light source to adjust outputs of beams reflected from the beam splitters, and a laser lamp system using the same.

A gear shift adjusting mechanism includes: an adjustment unit including a first slider; an adjustment target module including a second slider; and a switch unit including a first rotation shaft and a link member supported rotatably with respect to a fixing member about the first rotation shaft. The link member includes a first engaged part that is engaged with a first engaging part of the first slider and a second engaged part that is engaged with a second engaging part of the second slider. The switch unit moves at least one of the first rotation shaft, the first engaging part, or the second engaging part so that at least one of a first distance between the first rotation shaft and the first engaging part or a second distance between the first rotation shaft and the second engaging part is changed.

A lighting apparatus for a motor vehicle has a lighting module. The lighting module includes a laser light source for generating laser light, the laser light source having one or more laser diodes. The module includes an optical device onto which the laser light is incident and which is designed such that it generates a predefined symbol in the surroundings of the motor vehicle. The optical device has one or more holographic optical elements which are substantially non-absorbent to the laser light and which are designed to effect interference of the laser light by phase modulation thereof in order to generate the predefined symbol. The module includes an actuator system for moving at least one part of the lighting module. The actuator system has one or more actuators. A control device actuates the actuator system during operation of the illuminating device such that the position of the predefined symbol relative to the motor vehicle and/or the shape of the predefined symbol are changed by the actuator system.
