Abstract
A lighting device for vehicles having a housing in which is arranged a hologram light fixture that has a light source unit and has an optical unit with a hologram element for generating a predetermined lighting function. An auxiliary element is associated with the light source unit, by means of which light that is emitted by the light source unit can be deflected in the direction of the hologram element. In this design, the light source unit and/or the auxiliary element is arranged in the region of a side of the hologram element or in the region of a lateral extension of an edge of the hologram element extending in the direction of a central axis of the hologram element.
Claims11
A lighting device for a vehicle, the lighting device comprising:
- a housing;
- a hologram light fixture arranged in the housing, the hologram light fixture having a light source unit and an optical unit with a hologram element for generating a predetermined lighting function;
- and
- an auxiliary element associated with the light source unit, wherein via the auxiliary element, light that is emitted by the light source unit is adapted to be deflected and oriented in a direction of the hologram element to generate a virtual light source and to reconstruct a hologram,
- wherein the light source unit and/or the auxiliary element is arranged in a region of a side of the hologram element or in a region of a lateral extension of an edge of the hologram element extending in a direction of a central axis of the hologram element, and
- wherein with respect to a lateral direction that runs parallel to a primary direction of emission of the hologram element, the auxiliary element is arranged to be offset from the light source unit such that, in the lateral direction, a distance between the hologram element and the light source unit is smaller than a distance between the hologram element and the auxiliary element.
A lighting device for a vehicle, the lighting device comprising:
- a housing;
- a hologram light fixture arranged in the housing, the hologram light fixture having a light source unit and an optical unit with a hologram element for generating a predetermined lighting function;
- and
- an auxiliary element associated with the light source unit, wherein via the auxiliary element, light that is emitted by the light source unit is adapted to be deflected and oriented in a direction of the hologram element to generate a virtual light source and to reconstruct a hologram,
- wherein the light source unit and/or the auxiliary element is arranged in a region of a side of the hologram element or in a region of a lateral extension of an edge of the hologram element extending in a direction of a central axis of the hologram element,
- wherein the light source unit includes a first light source unit and a second light source unit and the auxiliary element includes a first auxiliary element and a second auxiliary element, and wherein the hologram element has at least two different optical structures so that a first optical structure serves in interaction with the first light source unit and with the first auxiliary element for the generation of a first lighting function, and a second optical structure serves in interaction with the second light source unit and with the second auxiliary element for the generation of a second lighting function, and
- wherein the first light source unit and the second light source unit and the first auxiliary element and the second auxiliary element, are in each case arranged in the region of opposite sides of the same hologram element.
