Lighting device and method for producing a lighting device

A method for producing a lighting device, comprising:

• forming a light guide in one piece from a light guide core and a protective layer;
• arranging the protective layer on a light exit side of the light guide, at least in a viewing area,
• bonding, welding or otherwise connecting a housing to a rear side of the light guide on a side facing away from a light emission side, so as to cover at least an entire viewing area of the rear side and seal the rear side in a dust-proof and dirt-proof manner, and
• forming a decoupling structure by a molded or embossed microstructure on the rear surface of the optical core and arranging the decoupling structure so as to deflect light, as a result of which the deflected light emerges from the light guide into the environment via the light exit side.

A method for producing a lighting device, comprising:

• forming a film composite comprising a touch-sensitive layer and a protective film;
• back-molding the film composite with a light guide core to form a one-piece light guide;
• arranging the protective film on a light exit side of the one-piece light guide such that the touch-sensitive layer is positioned between the core and the protective film;
• wherein the one-piece light guide is flat is configured such that its light emission side at least in one viewing area has a protective layer, applied to and forming an outer surface of the light emission side, directly connected to an optical fiber core;
• wherein the optical fiber core is connected via at least one coupling side, light can be coupled in from at least one light source;
• wherein, on a side opposite the light emission side, has a rear side with a decoupling structure, wherein the decoupling structure is formed by a molded or embossed microstructure on the rear surface of the optical core and is arranged to deflect light, as a result of which the deflected light emerges from the light guide into the environment via the light exit side, and
• wherein a housing, bonded, welded, or otherwise permanently connected to the rear side of the light guide on a side facing away from the light emission side, so as to cover at least the entire visible area 32 of the rear side and seal the rear side in a dust-proof and dirt-proof manner.
