In each case, at least one row of light-emitting diodes (LEDs) is provided above the embodiments according to FIGS. 1 to 4. see, which are arranged on a carrier strip 6. The carrier strip 6 extends over the entire length of the corresponding functional rail 1, 1 b and is fastened with its upper side or its lower side to a corresponding wall surface of the respective functional rail 1 to 1 b.

In the embodiment of Fig. 1, two carrier strips are provided, wherein a carrier strip 6 is fixed to a lower side of an upper edge web 3 of the functional rail 1. The other carrier strip with its associated LEDs 4 is provided on the outside on a side wall section of a hollow chamber 2 formed by the functional rail 1 (FIG. 1). In order to allow the light emission of the light radiation of the light emitting diodes 4 (LEDs) in the region of the edge web 3 upwards and in the region of the Seitenwandungsabschnittes in the hollow chamber 2, in the corresponding wall sections of the functional rail 1 one of the number and positioning of the LEDs 5 corresponding number and Positioning circular passages 5 is provided, into which the LEDs 4 protrude. The series of passages along the one wall section, namely the edge web 3 and along the other wall section, namely along the side wall of the hollow chamber 2, extends over the entire length of the functional rail 1, even if this is not recognizable in Fig. 1. Of course, it is possible to provide corresponding rows of light-emitting diodes, which are arranged on carrier strips 6, also on other wall sections of the functional rail 1. In a corresponding manner, a corresponding series of passages is then to be provided in the region of these wall sections, through which the light beams of the light emitting diodes can pass.

In the embodiment according to FIG. 2, the row of light-emitting diodes 4 together with their carrier strips 6 is fastened on the bottom of the hollow chamber 2, in particular by gluing. The carrier strip 6 and the row of light-emitting diodes are directed upward by a strip-like diffuser. be 7 covered, the comparative the light of the light-emitting diodes 4, point-shaped light sources and distribute over the entire length and width of the hollow chamber 2.

In the embodiment according to FIGS. 3 and 4, a row of light-emitting diodes 4 is fastened by means of a corresponding carrier strip or a similar carrier arrangement only in the region of the one upper edge section 3b. Also, the edge web 3b has a number of light-emitting diodes 4 corresponding number of passages into which the light-emitting diodes 4 protrude and can deliver appropriate light rays upwards. The essential difference from the preceding embodiments is that here the light-emitting diodes 4 can be controlled individually or in groups differently. For this purpose, an electronic control unit, not shown, is provided, which is connected to individual light-emitting diodes 4. In the region of the bottom of the hollow chamber of the functional rail 1 touch or touch sensors 10 are provided, which are in each case in communication with switching elements 9, which in turn are part of corresponding circuits of the control unit. In the guide rail 1 b a function carriage 8 is arranged longitudinally displaceable. The functional slide 8 is slidably mounted in the longitudinal slot of the functional rail 1b. For this purpose, it has a remaining above the edge webs 3b load portion and a remaining below the longitudinal slot in the hollow chamber of the functional rail 1b guide portion which is provided in the region of its underside with a control surface 11. The control surface 11 serves to activate the sensors 10. In the exemplary embodiment according to FIG. 4, the sensors 10 are designed as touch or tactile sensors which, when the control surface 11 of the functional slide 8 slides over, move downwards in the direction of the bottom of the hollow chamber of the functional rail 1b and thus inevitably cause the associated switching element 9 to close. As in the case of the embodiment according to FIG. 4, the control surface 11 of the functional slide 8 extends over a plurality of sensors 10 lying one behind the other, thus These are activated when passing over the functional slide 8 together or slightly delayed and remain in their activated state until the sliding over functional slide 8 has been removed. Subsequently, the sensors 10 inevitably return to their original position by spring force, in which they can be actuated again when the functional slide 8 is swept again. As soon as the corresponding switching elements 9 are actuated, the associated circuits close, so that the light-emitting diodes 4 located at the level of the function carriage 8 are activated. The sensors 10 and the associated switching elements 9 are each positioned at the level of the associated LEDs 4, so that the function carriage 8 in the moment in which he actuates the corresponding sensors 10 and switching elements 9 by means of its control surface 11, respectively in a corresponding instantaneous position S. (FIG. 3) also activates the associated light-emitting diodes. Thus, in the embodiment according to FIGS. 3 and 4, the light-emitting diodes 4 always shine, at the height of which the functional slide 8 is currently located.

In the embodiments according to FIGS. 5 and 6, lighting means in the form of electroluminescent foils 12 are provided, which are likewise designed in a strip-like manner and applied to a corresponding carrier material. The electroluminescent films 12 are connected via a converter 13 to a corresponding circuit and optionally a corresponding electronic or electrical control unit. In the embodiment according to FIG. 5, the corresponding foil strip is provided on the inside in the region of the hollow chamber 2c of the functional rail 1c, as can be seen in FIG. In the embodiment according to FIG. 6, the film strip of the electroluminescent film 12 is arranged in the region of an underside of an edge web of the functional rail 1d analogously to the arrangement of the light-emitting diode row according to FIG. 1. Here, too, a row of uniformly overlaps in the corresponding edge web of the functional rail 1d Length of the functional rail 1 d arranged distributed passages 14 provided by which can pass through the radiated by the electrically luminescent film 12 light upwards. The attachment of the corresponding film strip to the associated wall portion of the functional rail 1c or 1d is preferably carried out by gluing the film strip itself or an associated carrier strip.

Instead of a flat electroluminescent film 12 according to the embodiments of Figures 5 and 6, it is provided in the embodiment of FIG. 8, instead of a flat film strip to provide a round electroluminescent strand 15, which is connected in the same manner to a converter 17, as in the Electroluminescent films 12 according to the embodiments of Figures 5 and 6 was the case. Also as a round strand, the electroluminescent element can be connected by gluing with corresponding wall sections of the functional rail 1e. Preferably, the bonding takes place in a corner region of the functional rail 1e, as can be seen from FIG.

In the embodiment according to FIG. 7, a round-strand-shaped light guide 15e is provided along the edge web of the functional rail 1e instead of an electroluminescent round strand. The light guide 15e is frontally provided with a light-emitting diode unit 16, which forms the light source for the light guide 15e. The arrangement of the light guide 15e takes place in the embodiment of FIG. 7 in lateral edge or edge regions of the functional rail 1e. For this purpose, a groove or other type of recess is provided in the corresponding loading space limiting surface, which allows a laying of the light guide 15e over the entire length of the functional rail 1e.

Of course, both the optical waveguide 15e and the electroluminescent round strand 15 can also be arranged at other locations of the respective functional rail 1e. Preferably, the Order of corresponding round strands in corner areas or on marginal edges of the functional rail 1e.

In the embodiment according to FIGS. 9 and 10, in the region of a front end of the functional rail 1f, a high-energy light source in the form of a laser 18 is embedded in a corresponding loading space boundary surface and arranged there in a load space. The laser 18 is aligned coaxially to a central longitudinal axis of a hollow chamber of the functional rail 1f. The laser 18 can thus transmit a line-shaped light beam through the functional rail 1f along the hollow chamber. In the functional rail 1f, according to FIGS. 9 and 10, two slightly different functional carriages 8 and 8g are arranged, which are mounted so as to be slidable and lockable in the functional rail 1f analogously to the previously described embodiment. Both functional slides 8, 8g have optical functional elements 19 and 20 in order to be able to deflect the light beam of the laser 18. In the embodiment according to FIG. 9, a mirror 19, which is preferably curved convexly or concavely, is provided on the end side of the functional slide facing the laser 18, in order to distribute the light radiation within the hollow chamber of the functional rail 1f. In the embodiment according to FIG. 10, a prism or diffusing lens 20 is provided which deflects the laser beam of the laser 8 upwards in the direction of an operating knob 21 for the functional slide 8g. Instead of a prism or a diffusing lens, a simple deflecting mirror, which is preferably oriented at a 45 ° angle, can also be provided as an optical functional element. In the illustrated embodiment, the operating knob 21 has a structure made of an at least partially transparent material, so that the actuating button 21 starts to light when the laser 8 is activated. The actuating button 21 is used in particular for releasing a locking of the functional slide 8g in order subsequently to be able to displace the functional slide 8g along the functional rail 1f. Due to the illumination from below, the functional reliability 8g and in particular its operating button 21 are recognized and operated in the dark in a simple manner.
