Abstract
The present invention relates to a lighting device having a planer optical fiber and at least one light source device for illuminating a controllable spatial light modulator, wherein the optical fiber comprises a light-conducting core and a cover coating, and the light modulator comprises a pixel matrix, the light source device is disposed on the side of the optical fiber, and the light emitted by at least one light source of the light source device propagates laminarly in the optical fiber. The lighting unit according to the invention is characterized in that the planar optical fiber comprises a deflecting coating having a selective polarization function for laminarly decoupling and deflecting the evanescent wave field of the light propagating in the optical fiber, wherein the thickness of the cover coating reduces in the direction of light propagation.
