Abstract

An optoelectronic lamp device includes an optoelectronic semiconductor component including a top side including a light-emitting face, and a housing embedding the semiconductor component and leaving free the light-emitting face, wherein a housing face is coated with a light-scattering dielectric resist layer that may scatter light incident on a face of the resist layer facing away from the housing face.
