Abstract: The embodiments of the invention provide a multi-focal collimating lens (100) and a headlight assembly for an automotive low beam. The multi-focal collimating lens (100) includes a central collimating lens portion (101) and two total internal reflection lens portions (102) arranged on a left side and a right side of the central collimating lens portion (101). The central collimating lens portion (101) and the total internal reflection lens portions (102) share two focal points (103, 104) symmetrically located on both sides of a vertical symmetry plane (105) of the multi-focal collimating lens (100). An upper edge (106) and a lower edge (107) of the multi-focal collimating lens (100) are formed based on the two focal points (103, 104), so that the headlight assembly is able to generate a cut-off line of the automotive low beam in a far- field light pattern of the multifocal collimating lens (100).

Abstract: The present invention relates to the field of automotive front- lighting, and particularly to a front- lighting system for a vehicle. The front- lighting system (4, 7, 8, 9, 10) comprises: a first light source (BS1), a second light source (BS2), a first primary optics (411), a second primary optics (412), a transparent shutter (42), and a secondary optics (43). The first primary optics (411) is designed to receive light from the first light source (BS1) and project it onto the transparent shutter (42) and the secondary optics (43). The second primary optics (412) is designed to receive light from the second light source (BS2) and project it onto the transparent shutter (42). The transparent shutter (42) is designed to receive light from the first light source (BS 1) via the first primary optics (411) and prevent a lower part of it from entering the secondary optics (43). The transparent shutter (42) is further designed to receive light from the second light source (BS2) via the second primary optics (412) and project it onto the secondary optics (43). The secondary optics (43) is designed to receive light from the first primary optics (411) and the transparent shutter (42), and project it onto a road in front of the vehicle. The transparent shutter (42) comprises a flat or freeform light out-coupling surface (422) and micro-optical surfaces (423) adjacent to the light out-coupling surface (422).

Abstract: The invention provides a headlight device capable of generating two distinct, though possibly overlapping, beam portions, by means of a single integrated unit. The unit comprises two primary optical components for generating the two respective beam portions, and a single exit lens through which the combined beam is transmitted. A low beam having a stepped cut-off – to avoid glare to oncoming road users – may be generated by means of the provided device, with the cut off generated by means of a specially shaped collimating element, and the remaining spread of the beam generated by means of a downwardly reflecting reflector. Dual high and low beam functionality can alternatively be achieved, wherein the collimating element generates a high beam, and the reflector structure generates a low beam. By shaping and positioning the collimating element appropriately, a stepped cut off in the low beam may be still be provided in these embodiments.

Abstract: A lighting module includes a first light source that generates a low beam with a bright/dark cut-off line and a second light source. First optics redirects a first part of light from the first light source to create a main part of the low beam substantially below the bright/dark cut-off line. Second optics is spaced apart from the first optics and redirects a second part of light from the first light source to create a zone III beam of the low beam substantially above the bright/dark cut-off line and redirects a fourth part of light from the second light source to create a concentrated beam of the high beam in front of the vehicle. Third optics redirects a third part of light from the second light source to create a main part of a high beam.
