Abstract
There is provided a lighting system for a vehicle. The lighting system comprises a holographic projector and a light distribution system. The holographic projector comprises a hologram engine and a spatial light modulator. The hologram engine is arranged to output holograms. The spatial light modulator is arranged to display each hologram and spatially-modulate light in accordance with each hologram. The spatially-modulated light forms a holographic reconstruction, corresponding to each hologram, on a replay plane. The light distribution system comprises a plurality of optical fibres. Each optical fibre comprises an input optically-coupled to respective sub-area of the replay plane and an output optically coupled with an illumination sub-system of the vehicle.
Claims23
A lighting system for a vehicle, the system comprising:
- a holographic projector comprising:
- a hologram engine arranged to output holograms;
- a spatial light modulator arranged to display each hologram and spatially-modulate light in accordance with each hologram, wherein the spatially-modulated light forms a holographic reconstruction, corresponding to each hologram, on a replay plane;
- and
- a light distribution system comprising a plurality of optical fibres wherein each optical fibre comprises an input optically-coupled to respective sub-area of the replay plane and an output optically coupled with an illumination sub-system of the vehicle, the illumination sub-system being at least one selected from the group consisting of:
- an internal door handle light;
- an external door handle light;
- an electric window switch;
- a vanity mirror light;
- a reading light;
- a foot-well light;
- a welcome mat light;
- a door sill light and a wing mirror light.
A method of providing light to an illumination sub-system of a vehicle, the method comprising:
- providing a hologram to a spatial light modulator;
- displaying the hologram on the spatial light modulator;
- spatially modulating light in accordance with the hologram to form a holographic reconstruction, corresponding to the hologram, on a replay plane;
- providing light of the holographic reconstruction to an illumination sub-system of the vehicle using an optical fibre having an input optically-coupled to a sub-area of the replay plane illuminated by the holographic reconstruction and an output optically-coupled to the illumination sub-system, wherein the illumination sub-system is at least one selected from the group consisting of:
- an internal door handle light;
- an external door handle light;
- an electric window switch;
- a vanity mirror light;
- a reading light;
- a foot-well light;
- a welcome mat light;
- a door sill light and a wing mirror light.
