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.
Claims19
A lamp assembly for a vehicle, comprising:
- a plurality of light-emitting diodes (LEDs) mounted in or on the vehicle, the plurality of LEDs being arranged in a curvilinear pattern;
- a curved elongated optical member disposed longitudinally along the curvilinear pattern of the plurality of LEDs, the curved elongated optical member being configured to receive light emitted from the plurality of LEDs and project a corresponding plurality of lit images;
- an optical sheet disposed between the plurality of LEDs and the curved elongated optical member, the optical sheet being configured to homogenize the light received from the plurality of LEDs to provide a curved homogenous line image having a uniform intensity and light output;
- and
- a light-modifying element disposed on a portion of the curved elongated optical member to block light from the plurality of LEDs at certain angles.
A vehicle lamp assembly, comprising:
- a plurality of light-emitting diodes (LEDs) mounted to a printed-circuit board in or on the vehicle to form a linear array of LEDs;
- a primary light pipe 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;
- a light-modifying element disposed on a portion of the primary light pipe to block a portion of light from the plurality of LEDs;
- and
- a first optical sheet disposed adjacent to the primary light pipe for homogenizing the light from the primary light pipe to form a lit line image along a longitudinal length of the primary light pipe.
A vehicle lamp assembly, comprising:
- a plurality of light-emitting diodes (LEDs) mounted to a printed-circuit board in or on the vehicle to form a linear array of LEDs;
- a light pipe 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 light pipe, wherein the light pipe is disposed immediately adjacent to the linear array of LEDs such that no gap exists therebetween, thereby forming a plurality of spot images projected from the light pipe;
- an optical sheet disposed adjacent to the light pipe for homogenizing the light from the light pipe to form a lit line image along a longitudinal length of the light pipe, wherein the optical sheet is positioned at a first distance from the linear array of LEDs to form a gap therebetween;
- a diffuser lens disposed adjacent to the optical sheet opposite the light pipe for further homogenizing the light;
- and
- a light-modifying element disposed on a portion of the light pipe to block a portion of light from the plurality of LEDs.
