Abstract: The present disclosure relates to a headlamp lens for a vehicle headlamp, wherein the headlamp lens comprises a precision-molded body made of a transparent material, wherein the body comprises at least one light tunnel and a light-conducting part with at least one optically active light exit surface. The light tunnel comprises at least one light entry surface and merges with a bend in the light-conducting part to depict the sharp bend as a light/dark boundary by means of light coupled or radiated into the light entry surface. The surface of the light tunnel is at least partially convexly curved in the region of the bend.

Abstract: 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.

Abstract: A motor vehicle headlamp that includes a housing in which at least one main light source is arranged. Detachably attached to an external lens of the motor vehicle headlamp is at least one front housing, which has a light-guiding element and lamps for coupling light rays into the light-guiding element. The light rays are coupled out of the light-guiding element through an output structure. Further additional lamps that can give off light rays are arranged side by side in front of the external lens. The light rays given off by the lamps pass through the external lens and the front housing in the direction of an outside environment.
