The carrier element 22 contacts the carrier plate 34 in the present case.In the present case, each of the light entry surfaces 18 is arranged on an extension 42 of the primary optical element 16 (or of the main body 13). The carrier element 22 has a plurality of through-openings 44. Each extension 42 projects in the present case through a plug-through opening 44 of the carrier element 22. The light entry surfaces 18 can thus be placed in front of the respective light sources 14 in a targeted manner.The light entry surfaces 18 or the extensions 42 and the light sources 14 are arranged in a row in each case in the present case.The primary optical element 16 in the present case has a contact section 38 for contacting the carrier element 22. The contact section 38 is in the present case designed in the form of a step on each of the extensions 42 of the primary optical element 16 or its main body 13 (cf. FIG. 3 ). The primary optical element 16 can rest with the contact section 38 on the carrier element 22 or be braced against the latter. This bracing can be achieved, for example, by pressing the fastening element 24 against the fastening section 28. In other words, a force can be exerted on the fastening portion 28 in the direction of the carrier element 22 by means of the fastening element 24, wherein this force presses the primary optical element 16 and in particular its main body 13 (with the respective extensions 42) with the contact portion 38 against the carrier element 22 or presses it against the carrier element 22.

The light sources 14 can be turned on and / or turned off together, individually or in groups.The primary optical element 16 in the present case has four supporting extensions 30 (cf.

The support extensions 30 are arranged at a distance from the light entry surfaces 18.The carrier element 22 has four openings 32 in the present case, wherein the supporting extensions 30 project through the openings 32 (in the direction of the carrier plate 34). The support extensions 30 each contact the carrier plate 34 and are supported on the carrier plate 34. By means of the support extensions 30, a constant distance can be implemented between the primary optical element 16 or its main body 13 and thus the light entry surfaces 18 and the light sources 14 arranged on the carrier plate 34. Thus, by selecting a length of the supporting extensions 30, a desired distance between the light entry surfaces 18 and the light sources 14 can be set.The at least one support extension 30 of the support extensions 30 is thus supported on the carrier plate 34. The support extension 30 is connected on a side of the support extension 30 facing away from the carrier plate 34, in particular in one piece, to the main body 13 of the primary optical element 16, in which the light generated by the light sources 18 merges.

In other words, the primary optical element 16 has at least one support extension 30 for spacing the light entry surfaces 18 of the main body 13 from the light sources 14, in particular their light exit surfaces.Since the primary optical element 16 rests with the support extensions 30 on the carrier plate 34 or is braced against the latter, a contact section 38 according to the first exemplary embodiment is not necessary. It is nevertheless conceivable that the illumination device 10 according to the second exemplary embodiment can have a contact section 38 according to the first exemplary embodiment. The bracing of the primary optical element 16 can be achieved analogously (as described above) to the first exemplary embodiment by pressing the fastening element 24 against the fastening section 28.

It is likewise conceivable for the cross section of the compensating section 36 to be U-shaped or rectilinear. Mechanical oscillations and / or deformations can be compensated by the compensating section 36. The compensating section 36 forms in particular a mechanical decoupling between the main body 13 and the fastening section 28.The compensating section 36 adjoins the fastening section 28 in the present case by way of example. In the present case, the common cross section of the fastening section 28 and of the compensating section 36 is S-shaped. In other words, the common cross section of the fastening portion 28 and the compensating portion 36 is formed in an concertina shape.The compensating portion 36 is arranged between the main body 13 and the fastening portion 28 fixed to the rest of the illumination device 10 in order to compensate deformations of the primary optical element 16.
