The optical device (10, 20, 30, 40) comprises: a plurality of light sources (11); a plurality of primary optics (12) arranged in a matrix and configured to receive and redirect light from the plurality of light sources (11); and a secondary optics (13) configured to receive the redirected light from the plurality of primary optics (12) and project out the received light into a desired beam pattern. Each of the primary optics (12) is shaped as a light guide (22, 32, 42, 62a, 62b) with a light entrance face (221, 321) and a light exit face (222, 322, 622a, 622b, 722) at two opposite ends thereof, which light guide (22, 32, 42, 62a, 62b) is configured to guide light incident at the light entrance face (221, 321) via total internal reflection to the light exit face (222, 322, 622a, 622b, 722) where light is refracted out towards the secondary optics (13). Each light guide (22, 32, 42, 62a, 62b) further comprises a plurality of side faces (223, 323, 224, 324) extending between the light entrance face (221, 321) and the light exit face (222, 322, 622a, 622b, 722). For at least one light guide (22, 32, 42, 62a, 62b), at least one side face comprises a curved face (224, 324), whose curvatures at different positions are designed, by sweeping a polygonal line along a direction which is perpendicular to the desired direction and perpendicular to a light guiding direction of the at least one light guide (32), such that a first desired gradient light intensity distribution is projected out along a desired direction by the secondary optics.

Abstract: The present invention relates to an optical module (1) and an automotive frontlighting system of a motor vehicle comprising such an optical module (1). The optical module (1) comprises a light emitting element (21), a primary optics (22) and a secondary optics (13). Specifically, the light emitting element (21) comprises an array of light sources, such as an array of LEDs. In a similar way, the primary optics (22) comprises an array of primary lenses, wherein each primary lens is adapted to collimate light from a corresponding one of the light sources. The secondary optics (13) is further adapted to receive the collimated light from each primary lens and project it onto a road in front of the motor vehicle. A first distance between each light source and its corresponding primary lens, a second distance between the primary optics (22) and the secondary optics (13), a first focal length of each primary lens, and a second focal length of the secondary optics (13) are adapted such that light passing through a primary lens and originating from light sources other than the light source corresponding to this primary lens will exit this primary lens with an output angle large enough for preventing such light from entering the secondary optics (13).

The second primary optics (12, 72) is designed to receive light from the second light source (BS2) and project it onto the transparent shutter (14, 74). The transparent shutter (14, 74) is designed to receive light from the first light source (BS1) via the first primary optics (11, 61, 71) and prevent a lower part of it from entering the secondary optics (13, 63, 73). The transparent shutter (14, 74) is further designed to receive light from the second light source (BS2) via the second primary optics (12, 72) and project it onto the secondary optics (13, 63, 73). The secondary optics (13, 63, 73) is designed to receive light from the first primary optics (11, 61, 71) and the transparent shutter (14, 74), and project it onto a road in front of the vehicle. The transparent shutter (14, 74) comprises an air-exposed slit (15, 65, 75) designed to redirect the light received by the transparent shutter (14, 74) from the second light source (BS2) towards a middle axis (X) of the transparent shutter (14, 74).

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).
