[0054] As in the first exemplary embodiment of the air vent 1 according to the invention illustrated in FIG. 1, the at least one light source 12 can be associated with a second optical fiber 9, which extends along the central longitudinal axis of the housing 2 and is guided into the bearing approximately at the pivot point of the insert 5, wherein the first optical fiber 8 is in particular guided into the bearing from the side opposite the second optical fiber 9, and wherein the light emitted by the at least one light source 12 is at least partially coupled into the second optical fiber 9, and the second optical fiber 9 then couples the light into the first optical fiber 8.

[0055] In this context, it is provided in particular that the first optical fiber 8 and the second optical fiber 9 do not touch, but the first optical fiber 8 is configured so as to be convex or concave at the light coupling site, wherein the second optical fiber 9 is configured so as to be planar or even at the light outcoupling site.

[0056] Although not shown in FIG. 1, an optical element can be arranged between the first optical fiber 8 and the second optical fiber 9, in particular in the form of a lens and preferably in the form of a condenser lens.

[0057] The embodiment of the air vent 1 according to the invention illustrated in FIG. 2 is characterized in that the at least one light source 12 is associated with an elongated hollow body for light shielding, which extends along the central longitudinal axis of the housing 2 and is guided into the bearing approximately at the pivot point of the insert 5, wherein the light emitted by the at least one light source 12 is at least partially coupled into the first optical fiber 8 via the elongated hollow body.
