Abstract: A light guide (201) comprising a transparent element is presented. The transparent element comprises a first surface (203) for acting as a light-ingress surface and a second surface (204) for acting as a light-egress surface. The second surface comprises elevations (205) for directing a part of the light into directions sideward with respect to a direction in which another and greater part of the light exits the transparent element through the second surface. Each elevation is shaped to provide total internal reflection for a light beam on a first point of the surface of the elevation and refract the reflected light beam on a second point of the surface of the elevation so as to direct the light beam sideward. The sideward directed light enables an observer, who sees the light guide from a small viewing angle, to easily see whether the light is on or off.

Abstract: A device for modifying light distribution comprises a reflector surface (310) whose shape is at least partly based on a shape transformation directed to a geometric auxiliary surface (330). The shape transformation comprises i) division of the geometric auxiliary surface into longitudinal geometric surface segments (314', 315'), ii) displacements of at least some of the surface segments sideward so as to achieve a desired shape, and iii) addition of geometric connection-surfaces (316) between surface segments that are at least partly separated from each other by the displacements so as to form a stepped geometric surface corresponding to at least a part of the reflector surface. The geometric auxiliary surface can be select- ed according to a desired intensity distribution within an illumination pattern formable on a planar surface, whereas the shape obtained with the shape transformation can be selected according to the desired shape of the illumination pattern.

Abstract: An optical device (201) for modifying a light distribution pattern of a light source (202) is presented. The light source radiates first light beams to a first geometric quarter-space and second light beams to a second geometric quarter-space, where the first and second quarter-spaces are defined by mutually perpendicular geometric planes one of which constitutes a boundary between the first and second geometric quarter-spaces. The optical device comprises a lens-section (207) for modifying a light distribution pattern of the first light beams and a reflector surface (208) for reflecting at least a part of the second light beams from the second geometric quarter-space to the first geometric quarter-space. The reflector surface is shaped to resemble a wedge that points towards the first geometric quarter-space so as to provide total internal reflection and to direct the reflected second light beams to sideward directions.

Abstract: A low-beam headlight element (600) comprises a lens (301, 401, 501) for modifying the distribution pattern of light penetrating the lens (301, 401, 501), and a reflector element (302, 502) comprising a first end having a place for a light source (307) and a second end having an opening constituting a passage for the light penetrating the lens (301, 401, 501). The thickness of the lens (301, 401, 501) is shaped to decrease more strongly towards a first edge (303) of the lens than towards an opposite second edge (204) of lens (301, 401, 501) so as to provide more refractivity on a first area (205) of the lens (301, 401, 501) abutting on the first edge (303) than on a second area (206) of the lens (301, 401, 501) abutting on the second edge (204). The refractivity on the first area (205) produces a cutoff line (311, 411, 511) in a resulting light distribution pattern. Hence, for achieving a cutoff line (311, 411, 511) meandering in a desired way, there is no need for a screen element which converts light into heat.

Abstract: A process for fabricating an optical device comprises injecting (301) optical silicone into a mold cavity formed by two or more mutually matching mold-elements (202, 203), curing (302) the optical silicone contained by the mold cavity, and separating (303) the mold-elements from the optical device (201) constituted by the optical silicone. The reversible elasticity of the optical silicone after the curing phase is utilized in the process so that at least one of the mold-elements has an undercut (counterdraft) which causes a reversible deformation in the optical device when the mold-element is separated from the optical device. As the undercut (counterdraft) is allowable, the shape of the optical device as well as the dividing joints between the mold-elements can be designed more freely. For example, walls of the mold cavity corresponding to optically active surfaces of the optical device can be arranged to be free from dividing joints between the mold-elements.
