Abstract
A lighting device includes: at least one laser light source configured to emit a light beam; and a light conversion element associated with the at least one laser light source and arranged in the beam path of at least one light beam generated by at least one laser light source such that at least a portion of the light beam emitted by the at least one laser light source is directed onto the light conversion element, and in such a way that a laser light spot is illuminated on a face of the light conversion element facing the incident light beam, the light conversion element comprising a material which, through scattering, absorption and conversion of the incident laser light, emits and scatters light of a larger wavelength.
