A lighting device for a headlight includes a light-emitting element carrier having a longitudinal direction. At least one low-light-emitting element, at least one high-light-emitting element, and at least one position light-emitting element are arranged at the light-emitting element carrier. The at least one position light-emitting element is arranged, in respect of the longitudinal direction, in a front facing end zone of the light-emitting element carrier, and the at least one low-light-emitting element and the at least one high-light-emitting element in respect of the longitudinal direction are arranged behind the at least one position light-emitting element.

A lens holder which supports a projection lens is screwed and fixed to a bracket which supports a spatial light modulator. A positioning pin configured to position the lens holder in a left-right direction with respect to the bracket is inserted into a long hole which is formed in the bracket and extends in a lamp front-rear direction. The screwing and fixing is performed in a state where the positioning pin is inserted into the long hole and is appropriately moved in the lamp front-rear direction, so that the lens holder is restricted from being displaced in a left-right direction with respect to the bracket, and it is possible to finely adjust a positional relationship between the projection lens and the spatial light modulator in the lamp front-rear direction.

The present disclosure provides a projection lamp module and a headlamp device for a vehicle using the same, in which two headlamps implement the same brightness, images of the headlamps are maintained, and visibility of an image projected onto a road surface is improved even though even though a lamp having a lighting function of forming an image on a road surface is applied to any one of the headlamps for a vehicle.

A luminous motor-vehicle module including in a first light source, and a first reflective surface that is configured to collect and reflect the light rays emitted by the first light source into a first light beam, a second light source and a second reflective surface that is configured to collect and reflect the light rays emitted by said second light source into a second light beam, and an optical system configured to project the first and second light beams; the first and second light sources emitting the light rays in the same direction, the first and second reflective surfaces are offset along the optical axis and the optical system is configured to form an image of the second reflective surface.

A three-dimensional hologram image producing lamp for a vehicle comprises a light source, a hologram plate displaying a three-dimensional hologram image, a curved slope mirror having a reflecting surface shaped as a parabolic curved surface, facing the light source, and reflecting light, radiated from the light source, toward the hologram plate, and a housing disposed on a lamp receptacle of a vehicle body and having the hologram plate, the light source, and the curved slope mirror mounted thereon.

A lens for a vehicle including a light source part including a plurality of light sources that irradiate light, and a lens part that outputs the light irradiated by the light source part to a front side, and the lens part includes a first lens disposed on a front side of the light source part, and a thickness of which becomes smaller as it goes toward opposite sides with respect to a leftward/rightward direction, and a second lens disposed on a front side of the first lens and deflected to be disposed on a more rear side as it goes from one end to an opposite end thereof with respect to the leftward/rightward direction.

A flat light guide (1) for a vehicle lighting device, which includes a rear end (10) and a front end with a light output surface (13), the light guide (1) being defined between the two ends by a pair of side surfaces (11, 12). The light guide (1) has a base plane (X-Y) and at its rear end (10) is provided with at least one collimating element (2) arranged transversely or obliquely with respect to the plane (X-Y). Opposite the collimating element (2) is arranged an obliquely inclined reflective surface (3) to reflect light from the collimating element (2) into the flat light guide (1). The collimating element (2) is adapted for the light input from the light source into the light guide (1) which further guides the light between the side surfaces (11, 12) to the output surface (13).
