Abstract
In various embodiments, a lighting device includes at least one laser light source and a light wavelength conversion element. The light wavelength conversion element includes phosphor which is arranged on a surface region of a substrate and is used for wavelength conversion of the light emitted by the at least one laser light source. The light wavelength conversion element has a greater thickness at the edge of the surface region, provided with phosphor, of the substrate than at the surface centroid of the surface region, provided with phosphor, of the substrate. The thickness is respectively measured perpendicularly to the surface region, provided with phosphor, of the substrate.
