1. A light-emitting assembly, having;
a light-emitting element for emitting a light along a path,
an optical element for influencing the path of the light, and
a transparent insulating element, which is arranged in the path of the light between the light-emitting element and the optical element, wherein the insulating element comprises a material which is more thermally stable than that of the optical element, and
a surrounding element which is arranged so as to surround both the optical element and the insulating element in dust-tight fashion,
wherein the surrounding element has a hollow-cylindrical region and the optical element has a cylindrical outer surface which contacts the hollow-cylindrical region, and the insulating element has a cylindrical outer surface which contacts the hollow-cylindrical region of the surrounding element.
