摘要： 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).

摘要： 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).

摘要： A lighting device (10) includes an LED light source (12) and a concave reflector (16). The light source (12) is arranged such that light emitted is reflected by the reflector (16). The shield (18) is arranged in front of the reflector (16). A projection lens (20) is arranged to project light passing the shield (18). In order to efficiently use light emitted from the LED light source and to enable a projected illumination beam of high luminous flux, the LED light source (12) is arranged below an optical axis L of the projection lens (20).
