Abstract

A lighting device and a method for producing a lighting device are disclosed. In an embodiment, the lighting device includes a carrier, at least one optoelectronic illuminant arranged on the carrier, the illuminant configured to emit light into an emission area and a color scattering layer located in the emission area, the color scattering layer configured to generate a color by scattering of light at a surface of the color scattering layer facing away from the illuminant.
