Abstract
A vehicle exterior lamp assembly has an optical light transmission device having a first end, a second end opposite the first end and a side wall extending between the first end and the second end. A cover lens covering the second end of the optical light transmission device. One or more primary light sources are configured to input light into the first end of the optical light transmission device for emission as an output from the second end. A hologram is provided on the side wall of the optical light transmission device. A secondary light source is configured to illuminate the hologram to display an image on the side wall of the optical light transmission device.
Claims20
A vehicle exterior lamp assembly comprising:
- an optical light transmission device having a first end, a second end opposite the first end and a side wall extending between the first end and the second end;
- a cover lens covering the second end of the optical light transmission device;
- one or more primary light sources configured to input light into the first end of the optical light transmission device for emission as an output light beam from the second end;
- a hologram provided on the side wall of the optical light transmission device;
- and
- a secondary light source configured to illuminate the hologram to display an image on the side wall of the optical light transmission device such that the hologram is illuminated in a hologram image beam orthogonal to the output light beam.
A vehicle exterior tail lamp assembly comprising:
- a light guide blade having a rear end, a front end and a side wall extending between the front end and the rear end;
- a cover lens covering the rear end of the light guide blade;
- a plurality of primary light sources configured to input light to the front end of the light guide blade for emission as an output light beam from the rear end of the light guide blade;
- a hologram provided on the side wall of the light guide blade;
- and
- a secondary light source configured to illuminate the hologram to display an image on the side wall of the light guide blade such that the hologram is illuminated in a hologram image beam orthogonal to the output light beam.
