摘要： A light device, especially a signal lamp, for motor vehicles, comprising a carrier housing covered by a translucent cover, and an inner chamber in which at least one primary optical assembly is housed, and comprising a planar light guide to guide the light generated by a lighting unit. The light guide surface comprises a front output surface to emit light rays out of the light device and an input surface to bind light rays produced by the lighting unit. The light guide surface includes, on its side facing away from the front output surface, at least one reflective surface configured to direct light rays to, and through, the output surface out of the planar light guide to create, on the front output surface, an output light region with a light intensity which differs from light intensity shown by places adjacent to the region on the front output surface.

摘要： The light device comprises an internal chamber (2) that is covered by a translucent cover, which separates the light device from the external surroundings of the motor vehicle; inside the chamber, there is at least one lighting unit (3) whose active area (4) for the exit of light rays (10) from the lighting unit (3) is situated opposite the translucent cover and contains a light-conductive core (15) of an optically transparent material with an associated light unit (7) located opposite the entry area (9) of the light-conductive core (15) to emit light rays (10) into the body (14) of light-conductive core (15). Between the light-conductive core (15) and the translucent cover there is a functional layer (23) configured to focus the beams of light rays (10) that exit its surface averted from the light-conductive core (15) in a predetermined direction. The light device comprises a technological layer (24) that is configured for a total reflection of the light rays (10), which is in contact with the top surface (17) of the light-conductive core (15).

摘要： The light-conductive optical system comprises a planarly shaped light guide (1) made from an optically transparent material with an associated light unit (3) and a collimating element (2). The light guide (1) comprises an output surface (12) for the output of light rays (10) and a binding surface (11) to bind light rays (10) to the light guide (1). The output surface (12) and the binding surface (11) are situated on surfaces that transversally connect the top (5) and bottom surface (6) of the light guide (1) and the binding surface (11) comprises a partial surface (11c) situated opposite the output surface (22) of the collimating element (2) and a lateral partial surface (11a, 11b) at one or both sides of the partial surface (11c). The height (v) of the output surface (22) is bigger than the thickness (t) of the light guide (1) so the output surface (22) reaches above the top surface (5) and/or below the bottom surface (6) of the light guide (1) with its overlapping part (8, 9). The light guide (1) is, for each overlapping part (8, 9), fitted with at least a pair of reflective means (4a, 4b; 4c) comprising the first reflective means (4a, 4b) situated opposite the overlapping part (8, 9) to bind at least a part of light rays (10) exiting from the overlapping part (8, 9) and to reflect them to the second reflective means (4c) adapted to direct light rays (10) against the lateral partial surface (11a, 11b).

摘要： The lighting unit (3) comprises a light guide (15) to lead light rays (10) from at least one light source (11) wherein the light guide (15) comprises the front surface (17) and the opposite rear surface (18). The front surface (17) comprises exit areas (30) for the exit of light rays (10) from the light guide (15), and intermediate areas (19) positioned between the exit areas (30) and configured for total reflection of light rays (10) passing along the light guide (15). The lighting unit (3) further comprising a light assembly (23) situated against the front surface (17) of the light guide (15) and comprising optical elements (26) containing a bearing area (14) with which the optical elements (26) are connected to the opposite exit areas (30) directly or indirectly in such a way that transitional layers (24) are situated between the exit areas (30) and bearing areas (14). The optical elements (26) are configured to bind light rays (10) falling onto the exit areas (30) and to emit them from the exit surface (29) of the optical elements (26) averted from the light guide (15), in a predetermined direction or directions.

摘要： An optical system for a lighting device, comprising a light-guiding optical part configured for spreading light beams generated by light sources situated opposite to a rear side of the optical part. Light beams are coupled into the light-guiding optical part, and after passing through the light-guiding optical part the light beams are emitted through its output surface. Rear side of light-guiding optical part is equipped with macroscopic cavities, each pair of adjacent macroscopic cavities forming between themselves an optical segment, whose two sides, which separate the optical segment from the pair of macroscopic cavities, comprise a reflective surface. The optical segment comprises a rear surface on the rear side, opposite to which a light source is positioned. The reflective surfaces are configured for reflecting a part of the light beams, which were coupled through the rear surface into the optical segment, and then directing them to the output surface.
