Abstract

A lighting device includes lens which delimits the inner region of the lighting device and is configured so that light exits outwards from the inner region. The lighting device includes one or more light sources in the inner region to emit a first light radiation in a first wavelength range, the lens being non-transparent to the first light radiation. The inner region also includes one or more elements, each of which contains a photoluminescent phosphor, the element(s) being arranged to be illuminated by the first light radiation. The photoluminescent phosphor is configured to emit a second light radiation in a second wavelength range, based on the first light radiation illuminating the element(s), the second light radiation at least partly exiting through the lens which is transparent to at least a part of the second light radiation.
