The present invention relates to an optical element (1), an optical module and a vehicle. The optical element (1) comprises: a light incident section (10) for receiving light directly from a light source; a light exit section (30) having a focal plane (P); and a third section (20) that directs light from the light incident section (10) toward the light exit section (30) in a predetermined manner to generate a predetermined low beam distribution or high beam distribution, where the optical element (1) is implemented integrally.

Low beam headlight that can be obtained with small installation length and high light/energy output are described. A light source arrangement is provided, which generates a light cone of light that is less divergent in a first transverse direction than in a second transverse direction perpendicular to the first transverse direction, and this light source arrangement is used to illuminate three lens arrays arranged next to one another along the second transverse direction, which are thus each irradiated on the input side by an associated one among segments of the light cone arranged next to one another in the second transverse direction and output low beam on the output side with a luminous intensity angle distribution modified with respect to the light cone.

An optical device comprising a first surface with a plurality of micro sized facets, each facet having a respective orientation. Said plurality of facets having an optical axis which extends parallel to the normal vector to an average orientation of all said respective orientations. The plurality of facets comprising at least a first and a second group of facets, each group is formed by a respective number of at least twenty-five compactly arranged neighboring facets. Each group is arranged to generate during operation a respective, mutually identical whole pattern. Each facet in a respective group is arranged to display a sub-pattern of said respective whole pattern. The whole patterns are mutually superpositioned.

A headlight includes a housing, a light source module, a light shielding unit and a lens. The housing defines a reflection space, and a channel in front of the reflection space. The light source module is mounted in the reflection space, and is configured to emit a light beam reflected into the channel. The light shielding unit includes a light shielding plate mounted in the channel for shielding the light beam passing through the channel to make the light beam have a cutoff line. The lens is disposed in front of the light shielding unit, and includes a main focusing portion, and a supplementary portion protruding from the main focusing portion toward the light shielding plate for guiding the light beam to an area above the cutoff line.

An optical surface for softening a light/dark border of a lighting device for vehicles, having a grid of lens elements distributed over a base surface, by means of which a light bundle passing through the optical surface can be diffused in relation to a main direction, wherein the lens elements are each designed as micro-lens elements, which, on one hand, exhibit a central main emission surface, which follows a contour of the base surface, by means of which the light beams of the light bundle are deflected in a main direction corresponding to the contour of the base surface, and on the other hand, exhibit subsidiary emission surfaces, running at an angle to the central main emission surface, by means of which light beams of the light bundle are diffused in a diffusion direction in relation to the main direction.

There are instances of vehicular lighting in prior art where a significant amount of effectively distributed light radiating from a projection lens is lost. The invention is provided with a semiconductor-type light source (2) and a projection lens (3). The projection lens (3) has an optically active portion (32) transmitting light from the semiconductor-type light source (2), and an optically inactive portion (33). The optically inactive portion (33) of the projection lens (3) is provided with a trimmed portion (33U, 33D) resulting from cutting away a portion of a base shape. As a result, the invention allows the amount of loss in the effectively distributed light radiating from the projection lens (3) to be as small as possible.
