Abstract: An optical device comprising at least one lamp is disclosed. The lamp comprises an output face for the light, and an image mask is mounted on said output face.

Abstract: In an embodiment an optoelectronic component includes a first joining partner including an LED chip with a structured light-emitting surface and a compensation layer applied to the light-emitting surface, wherein the compensation layer has a surface facing away from the light-emitting surface and spaced apart from the light-emitting surface, and wherein the surface forms a first connecting surface, a second joining partner having a second connecting surface, the first and second connecting surfaces being arranged such that they face each other and a bonding layer made of a film of low-melting glass having a layer thickness of not more than 1 ?m, wherein the bonding layer bonds the first and second connecting surfaces together, wherein the structure of the light-emitting surface is embedded in the compensation layer, and wherein the first and second connecting surfaces are smooth such that their surface roughness, expressed as center-line roughness, is less than or equal to 50 nm.
