Title
(EN) IMPROVED ILLUMINATION DEVICE
(FR) DISPOSITIF D'ÉCLAIRAGE AMÉLIORÉ
Abstract
(EN)
A device comprising: an illumination device for emitting an illumination beam, the illumination device comprising: an emitter array comprising multiple light emitters; and a meta-structure or micro-prism array comprising multiple transmission areas, the meta-structure of micro-prisms being positioned to receive light emitted from the emitter array, in which light from the meta-structure of micro-prism forms the illumination beam, in which a first one of said multiple transmission areas is arranged to emit light in a different direction than a second one of said multiple transmission areas.
