Abstract
A door frame for a vehicle includes a holographic door sill panel in a lower door frame portion, a suitable lighting assembly in a lateral door frame portion, a holographic door sill panel suitable for such a door frame, as well as a system that is composed of the holographic door sill panel and the lighting assembly and suitable for such a door frame.
Claims19
A door frame for a vehicle, comprising:
- a holographic door sill strip disposed in a lower door frame section;
- an illumination arrangement that is arranged in at least one lateral door frame section and is configured to illuminate the holographic door sill strip, the illumination arrangement comprising at least one light source,
- wherein the holographic door sill strip comprises a planar element having a thickness perpendicular to a planar extent of at most 3 mm, which includes at least one planar, reflective holographic structure that is configured to generate a holographic light function in a field of view,
- wherein the holographic structure is configured to generate the holographic light function when illuminated by the illumination arrangement, and
- wherein the illumination arrangement and the holographic door sill strip are arranged relative to one another for the illumination of the holographic structure at a centroid angle which is within 10° of a Brewster angle of the holographic door sill strip.
A holographic door sill strip for a door frame for a vehicle, wherein an illumination arrangement is arranged in at least one lateral door frame section and is configured to illuminate the holographic door sill strip, the illumination arrangement comprising at least one light source, the holographic door sill strip comprising:
- a planar element having a thickness perpendicular to a planar extent of at most 3 mm, which includes at least one planar, reflective holographic structure that is configured to generate a holographic light function in a field of view,
- wherein the holographic structure is configured to generate the holographic light function when illuminated by the illumination arrangement, and
- wherein the illumination arrangement and the holographic door sill strip are arranged relative to one another for the illumination of the holographic structure at a centroid angle which is within 10° of a Brewster angle of the holographic door sill strip.
A system, comprising:
- a holographic door sill strip, comprising a planar element having a thickness perpendicular to a planar extent of at most 3 mm, which includes at least one planar, holographic structure that is configured to generate a holographic light function in a field of view;
- and
- an illumination arrangement configured to illuminate the holographic door sill strip, comprising at least one light source,
- wherein the holographic structure is configured to generate the holographic light function when illuminated by the illumination arrangement, and
- wherein the illumination arrangement and the holographic door sill strip are arranged relative to one another for the illumination of the holographic structure at a centroid angle which is within 10° of a Brewster angle of the holographic door sill strip.
A holographic door sill strip for a door frame for a vehicle, wherein an illumination arrangement is arranged in at least one lateral door frame section and is configured to illuminate the holographic door sill strip, the illumination arrangement comprising at least one light source, the holographic door sill strip comprising:
- a planar element having a thickness perpendicular to a planar extent of at most 3 mm, which includes at least one planar, reflective holographic structure that is configured to generate a holographic light function in a field of view,
- wherein the holographic structure is configured to generate the holographic light function when illuminated by the illumination arrangement, and
- wherein the illumination arrangement is configured to illuminate the holographic structure with an angular spectrum around a centroid angle, with the result that at least 30% of the light rays from the illumination arrangement light the holographic structure, and
- wherein an intensity distribution of the illumination light is homogeneous and has a ratio of minimum intensity to maximum intensity of greater than 0.8.
