The illumination unit 510a, 510b comprises two contact elements 518a, 518b which are respectively connected to the illumination element 516 and to the two electrical conductors 514a, 514b and which respectively provide an electrical and mechanical connection of the illumination element 516 to one of the electrical conductors 514a, 514b are. The contact elements 518a, 518b are identical. However, it is also conceivable that the contact elements 518a, 518b are formed at least partially different. The contact elements 518a, 518b are formed of an electrically conductive material. The contact elements 518a, 518b are formed of a metal. However, other materials that appear appropriate to a person skilled in the art are also conceivable.

For the sake of simplicity, only one of the contact elements 518a, 518b of the illumination unit 510a, 510b is described as representative. The contact element 518a, 518b is connected to one, parallel to a main radiation direction 540 of the lighting 516, a lens 538 opposite underside 544 of the lighting element 516 fixed. The contact element 518 a, 518 b is fixedly connected to the lighting element 516. The contact element 518a, 518b is integrally connected to the illumination element 516. The contact element 518 a, 518 b is connected by a solder connection, not shown, with the

Illuminating element 516 connected. However, it is also conceivable for the contact element 518a, 518b to be connected to the illumination element 516 in another manner that appears appropriate to a person skilled in the art, such as, for example, by means of a welded or adhesive connection.

The contact element 518a, 518b is at least partially formed as a cutting element 594a, 594b. The contact element 518a, 518b is formed as a cutting element 594a, 594b. The contact element 518a, 518b is pin-shaped. The contact element 518a, 518b is designed as a contact pin. The contact element 518a, 518b has, viewed in a main extension direction of the contact element 518a, 518b, a cutting edge 568a, 568b facing away from the illumination element 516 at a end viewed in a main radiation direction 540, which cuts through an insulation of the electrical conductor 514a , 514b is provided. The contact element 518a, 518b, viewed in the main extension direction of the contact element 518a, 518b, is sharpened or pointed at an end remote from the illumination element 516. The contact element 518a, 518b is formed as a punching element. However, it is also conceivable other embodiments of the cutting edge 568a, 568b that appear appropriate to a person skilled in the art, such as, for example, an elongated knife-like cutting edge.

When the lighting element 516 is mounted on the electrical conductors 514a, 514b, the lighting element 516 to which the contact elements 518a, 518b are fastened is moved toward the electrical conductors 514a, 514b perpendicular to a main extension direction of the electrical conductors 514a, 514b.

The electrical conductors 514a, 514b are separated from each other and are individually connected via a respective contact element 518a, 518b with the lighting element 516 (Figure 5a). For mounting the lighting element 516 to the electrical conductors 514a, 514b, the electrical conductors 514a, 514b are added by a device, which is not described in further detail, at a defined distance from each other. fixed on each other. In an alternative embodiment, the electrical conductors 514a, 514b are interconnected and formed as a double strand (Figure 5b). As a result, an advantageously simple guidance and positioning of the lighting element 516 relative to the electrical conductors 514a, 514b can be achieved. However, it is also conceivable that the electrical conductors 514a,

514b integrated in a textile substrate, in particular woven, are.

The contact elements 518a, 518b are each pressed against the electrical conductors 514a, 514b with the sharpened end, perpendicular to the main extension direction of the electrical conductors 514a, 514b. The contact elements 518a, 518b penetrate the insulation of the electrical conductors 514a, 514b. The contact elements 518a, 518b are further pressed by the electrical conductors 514a, 514b, so that the contact elements 518a, 518b displace the individual wires of the electrical conductors 514a, 514b formed as strands and pierce the insulation on a side opposite to an entry point. The

Contact elements 518a, 518b are thereby positioned so that the contact elements 518a, 518b are guided along a diameter of the electrical conductors 514a, 514b through the electrical conductors 514a, 514b. In this punching through of the contact elements 518a, 518b by a respective electrical conductor 514a, 514b ensures the elastic insulation of the electrical

Conductor 514a, 514b ensure that the displaced individual wires of the electrical conductors 514a, 514b formed as strands are pressed against the respective contact element 518a, 518b by a resistance to a cross-sectional enlargement of the electrical conductors 514a, 514b as the contact elements 518a, 518b penetrate. As a result, a good electrical connection of the electrical conductors 514a, 514b with one of the contact elements 518a, 518b can be achieved. In addition, this results in a frictional coupling in each case between one of the electrical conductors 514a, 514b and one of the contact elements 518a, 518b. The insulation of the electrical conductors 514b is formed on polymer base, for example of silicone. In an assembled state, the pointed ends of the contact elements 518a, 518b project through the electrical conductors 514a, 514b.

The embodiments of lighting units 510c, 510d shown in FIGS. 5c and 5d differ only in a fuse of the Illumination element 516 relative to electrical conductors 514c, 514d of the embodiment of the lighting unit 510a shown in Figure 5a. In order to secure the lighting element 516 relative to the electrical conductors 514c in an assembled state, the lighting unit 510c furthermore has at least one securing element 526c. A first embodiment of the at least one

Fuse element 526c is shown in FIG. 5c. The lighting unit 510c has a plurality of fuse elements 526c. A number of the fuse elements 526c correspond to a number of contact elements 518c. The lighting unit 510c has two fuse elements 526c. However, it is also conceivable for the lighting unit 510c to comprise another number of fuse elements 526c, for example four fuse elements 526c, which appears sensible to a person skilled in the art. The fuse elements 526c are formed integrally with the contact elements 518c. The securing elements 526c are each designed as a rivet head. To secure the lighting element 516 relative to the electrical conductors 514c, the pointed ends of the contact elements 518c projecting from the electrical conductors 514c are reshaped so that they each form a rivet head. Alternatively or additionally, other embodiments of the securing elements 526c that appear appropriate to a person skilled in the art, such as, for example, barbs formed on the contact elements 518c or by bending over of the pointed ones, are also possible

Ends of the contact elements 518c, conceivable. The fuse elements 526c are provided to prevent the contact elements 518c from slipping out of the electrical conductors 514c in an assembled state. The contact elements 518c are each at least partially formed as a cutting element 594c. The contact elements 518c are each formed as a cutting element 594c.

FIG. 5 d shows an alternative exemplary embodiment of at least one fuse element 526 d of the lighting unit 510 d. The lighting unit 510d has a fuse element 526d. The fuse element 526d is intended to contact the pointed ends of contact elements 518d, which in an assembled state extend through the electrical conductors 514d, in an assembled state and to prevent them from slipping out. The fuse element 526d is formed from an electrically insulating material, such as silicone or a plastic. The fuse element 526d is positioned on the side of the electrical conductors 514d on which the contact elements 518d emerge in an assembled state. When the lighting element 516 is mounted on the electrical conductors 514d, the contact elements 518d enter the fuse element 526d after they have emerged from the insulation of the electrical conductors 514d. A thickness of the fuse element 526d, viewed in the main extension direction of the contact elements 518d in an assembled state, is greater than a length of the ends of the contact elements 518d, which in an assembled state protrude from the electrical conductors 514d. The fuse element 526d encloses the ends of the contact elements 518d, which protrude in an assembled state of the electrical conductors 514d in an assembled state completely. In an assembled state, the contact elements 518d are firmly and captively connected to the fuse element 526d. The contact elements 518d are each at least partially as a cutting element

594d formed. The contact elements 518d are each formed as a cutting element 594d. The contact elements 518d are frictionally, in particular by a static friction between the fuse element 526d and the respective contact element 518d, connected to the fuse element 526d. In addition, the contact elements 518d each have a barb-shaped geometry at the sharpened ends. The contact elements 518d each have a plurality of barbs 596, which are provided for a, in particular permanent, positive connection with the securing element 526d. The barbs 596 are arranged in the region of a cutting edge 568d of the contact elements 518d. The barbs 596 engage in a material of the securing element 526d upon movement of the contact elements 518d away from the securing element 526d and thus prevent slipping out of the contact elements 518d from the securing element 526d in an assembled state. However, it is also conceivable that the contact elements 518d are firmly connected to the fuse element 526d in another manner which appears appropriate to a person skilled in the art. For example, it is conceivable for the securing element 526d to have recesses, in particular bores, which are provided to respectively receive a contact element 518d and into which an adhesive is filled, which is cured after a joining operation with the contact elements 518d. This allows a cohesive connection between the contact elements 518d and the fuse element 526d are achieved. In addition, it is also conceivable to design the securing element 526d in several parts, so that, for example, each of the contact elements 518d is assigned a separate securing element 526d.

The, in particular integrally formed, securing element 526d also has recesses 598, which are each provided for receiving one of, in particular separately arranged, electrical conductors 514d. The recesses 598 are each groove-shaped. As a result, the electrical conductors 514d can be positioned, for example, for a subsequent method step and fixed to one another at a defined distance.

In the method step 32, the contact elements 118a of the illumination unit 110a are each connected to the electrical conductors 114 of the illumination unit 110a. The contact elements 118a are connected to the electrical conductors 114 by crimping, soldering, welding, gluing, by an insulation displacement connection and / or in another manner that appears appropriate to a person skilled in the art. The method steps 30, 32 can be performed in any order. The method also has a further method step 76, in which an unillustrated carrier is mounted around the illumination elements 116 and the electrical conductors 114 of the illumination unit 110a. The carrier completely encloses the lighting elements 116 and the electrical conductors 114 in an assembled state. The carrier has a round cross-section.

The carrier has a constant diameter when viewed in a main direction of extension of the electrical conductors 114 in an assembled state. However, it is also conceivable that the carrier viewed in the main extension direction of the electrical conductors 114 in an assembled state, has varying diameters, which are in particular each formed around one of the lighting elements 116 around larger than in a region between the lighting elements 116. Further it is also conceivable that the carrier is designed in several parts, so that the carrier, for example, each encloses only the areas around one of the lighting elements 116 and is at least partially interrupted in the area between the lighting elements 116. The carrier is formed of a plastic. The carrier is made of silicone. However, it is also conceivable that the carrier is formed from another material that appears appropriate to a person skilled in the art, such as, for example, TPE or PU R. In the further method step 76, the carrier is injected onto the illumination elements 116 and the electrical conductors 114. Furthermore, it is conceivable for the carrier to be formed from a plurality of different materials which can be applied successively, as a result of which a particularly robust embodiment of the carrier can be achieved.
