Disclosed is a vehicle projection lamp that improves the definition of an image. An aspect of the present embodiment provides a vehicle projection lamp that reduces a distortion occurring in an image and improves the definition of the image when outputting the image to the ground. The projection lamp includes a light source; a substrate; a collimator located in front of the light source; a lens array unit; a fixing unit; an upper housing; and a lower housing.

A lighting device for vehicles, comprising a housing containing a light source and an optical unit. The optical unit has a microstructured surface having a plurality of microstructure elements. The microstructure elements are formed from a limited selection of microstructure elements formed differently in at least two extension directions of the surface.

A light-transmitting resin member is provided that can inhibit color appearance in which the light-transmitting resin member appears to be colored depending on a viewpoint position. Provided is a light-transmitting resin member, in at least a part of a surface of which a plurality of groove structures configured with a plurality of linear protrusion portions and a plurality of linear recess portions are formed and in which the linear protrusion portions and the linear recess portions extend in directions parallel with each other and the grooves are formed at a pitch at which transmittance of visible light incident at an incident angle in a predetermined range becomes approximately constant, the visible light being incident on a region, in which the grooves are formed, in the surface, the visible light being transmitted through the light-transmitting resin member.

Disclosed is a lighting device for a vehicle according to the present disclosure including: a housing; a lens made of a transparent material, coupled to the housing, and covering an opening provided in the housing; a light source installed in the housing and configured to emit light toward the lens; a first pattern layer disposed between the light source and the lens and including one or more first pattern portions; and a second pattern layer disposed between the first pattern layer and the lens and including one or more second pattern portions.

The optical device is intended to be placed in a housing to form a light signal lamp for a vehicle. The optical device includes, along the longitudinal direction: an input portion receiving rays emitted by a light source; a middle portion having two lateral faces spaced from each other along a transverse direction; an output portion including an output face through which the rays which have propagated in the optical device are emitted. The output portion comprises at least one module having lateral faces which, when viewed in the elevation direction, have an ogive shape and which define a front ridge extending substantially in a plane parallel to a plane.

A light-transmitting resin member is provided that can inhibit color appearance in which the light-transmitting resin member appears to be colored depending on a viewpoint position. Provided is a light-transmitting resin member, in at least a part of a surface of which a plurality of groove structures configured with a plurality of linear protrusion portions and a plurality of linear recess portions are formed and in which the linear protrusion portions and the linear recess portions extend in directions parallel with each other and the grooves are formed at a pitch at which transmittance of visible light incident at an incident angle in a predetermined range becomes approximately constant, the visible light being incident on a region, in which the grooves are formed, in the surface, the visible light being transmitted through the light-transmitting resin member.

A lamp for a vehicle including a light source part to emit light and a light guide part to receive light emitted from the light source part and to output the light from a front side of the light guide part. The light guide part includes: a guide body including an input surface disposed at an end of the guide body in an extension direction of the light guide part to which the light emitted from the light source part is input; a reflective surface formed on a rear surface of the guide body, and having a reflective optic part configured to reflect the light input through the input surface to the front side of the light guide part; and an output surface to output the light to an outer surface of the guide body. The reflective optic part includes a plurality of first reflective optics and second reflective optics.

Signal light or illumination device for a motor vehicle or for a motor vehicle headlight, comprising a light source, a light guiding body associated with the light source, wherein the light guiding body has a first section, a second section, and a first deflection element, wherein the first section is designed as a first light guiding channel and the second section is designed as a second light guiding channel, wherein the first deflection element connects the first section to the second section in a light-guiding manner, wherein the first light guiding channel has optical structures, which are designed to deflect light rays entering the first light channel, wherein the deflection by the optical structures is such that deflected light illuminates deflection elements of the second section substantially uniformly in such a way that light exiting the second section has a constant light intensity.

A lighting device for vehicles, comprising a housing containing a light source and an optical unit. The optical unit has a microstructured surface having a plurality of microstructure elements. The microstructure elements are formed from a limited selection of microstructure elements formed differently in at least two extension directions of the surface.

A lighting device for a motor vehicle is provided with numerous light sources, at least one optical component in the form of a microstructured film and/or microstructured optical panel, and a collecting and/or focusing lens. The lighting device is configured such that the light from the light sources passes through the collecting and/or focusing lens before passing through the at least one optical component.
