摘要： Disclosed are PBS-based ADB function adjustment method and an intelligent vehicle light module therefor. A light source system and a light control element constitute an intelligent illumination light control system. One part of light rays emitted by the intelligent illumination light control system penetrate through a PBS to form an illumination light shape, and the other part of the light rays emitted by the intelligent illumination light control system are reflected by the PBS in a direction opposite to a photosensitive chip integrated circuit. Ambient light enters an imaging lens group in a direction opposite to an illumination light path, and one part of the ambient light is reflected by the PBS to the photosensitive chip integrated circuit to form an information source for dynamic control of the light control system.

摘要： A lamp assembly for a vehicle includes a plurality of light-emitting diodes (LEDs) mounted in or on the vehicle and arranged in a linear pattern. An elongated optical member is disposed longitudinally along the linear pattern of LEDs. The elongated optical member is configured to receive light emitted from the LEDs and project a corresponding plurality of lit images. A vehicle lamp assembly includes a plurality of LEDs mounted to a printed-circuit board to form a linear array. A primary light pipe is disposed adjacent to the linear array of LEDs and aligned longitudinally along the linear array of LEDs, such that light emitted from each of the LEDs of the linear array traverses radially through the primary light pipe.

摘要： A lighting and/or signaling device comprising a container body which delimits a containment seat that houses a first luminous source adapted to emit a first luminous beam, and a second luminous source adapted to emit a second luminous beam. The containment seat adapted to be at least partially crossed by the luminous beams produced by said luminous sources, so as to transmit the luminous beams outside the containment seat. The containment seat is divided into a first compartment which houses the first luminous source and into a second compartment which houses the second luminous source. The lenticular body comprises a first transmission portion, facing the first compartment that transmits, at least partially, towards the outside the first luminous beam, a second transmission portion facing the second compartment that transmits, at least partially, towards the outside the second luminous beam. An opaque portion, is interposed between the first and second transmission portions so as to conceal the view of the first and second luminous sources.
