Preferably, the design is such that in one step, the lighting module 3 mechanically arrange on the busbar 1 and can produce the said electrical connection.

Furthermore, the light band system has a connection element 5, which may be arranged, for example, on the light module 3. In Fig. 3, a possible embodiment of the connecting element 5 is schematically outlined. The connection element 5 is configured to sever or interrupt the electrical conductor 2 for the purpose of establishing the electrical connection, so that two conductor end pieces 25, 26 are formed and the two conductor end pieces 25, 26 instead connect via the LED light source 4.

In this way, therefore, the current can be passed through the LED light source 4 and then "feed" back into the busbar 1.

In particular, the LED light source 4 can be switched electrically in series in the conductor 2 in this way.

In the example sketched in FIG. 3, the connecting element 5 has a first cutting element 51 and a second cutting element 52, the design being such that a piece 29 of the conductor 2 is cut out for cutting through the conductor 2 by the two cutting elements 51, 52 mentioned becomes. Further, in this example, the LED light source 4 is connected in a conductor portion 6, the conductor portion 6 having a first conductor portion end portion 61 and a second conductor portion end portion 62 and electrically connecting the first conductor end portion 25 to the first conductor portion to make the electrical connection. End portion 61 is connected and the second conductor end 26 with the second conductor portion end portion 62nd

Preferably, the first conductor portion end portion 61 is formed directly adjacent to the first cutting element 51 or arranged on the latter; the same applies to the second conductor section end region 62 and the second cutting element 52.

The conductor section 6 with the LED light source 4 extends accordingly at least partially in the lighting module. 3

In Fig. 2a a horizontal longitudinal section sketch is sketched to a corresponding embodiment. Sketched is the busbar 1 and the electrical conductor 2 therein, which here has a portion 21 which is aligned parallel to the longitudinal axis L of the busbar 1 extending. FIG. 2b shows a corresponding vertical longitudinal section sketch at the level of said section 21, whereby the light-emitting module 3 is still positioned separately from the connection to the busbar 1, that is to say from the latter; in Fig. 2c is a corresponding sketch after mounting the light module 3 on the busbar 1 is shown.

Before the lighting module 3 is connected to the busbar 1, the portion 21 of the conductor 2 - as indicated in Fig. 2b - extend without interruption. To establish the electrical connection between the LED light source 4 and the conductor 2, the section 21 of the conductor 2 is interrupted by means of the connection element 5 as described above, so that the two conductor end pieces 25, 26 are formed and the latter then via the LED light source. 4 electrically connected again. In Fig. 2c, the cut out by the connecting element 5 piece 29 of the conductor 2 is indicated by two slashes.

In the figures 4a to 4c, a further embodiment is outlined, wherein the reference numerals are used in an analogous manner. Unless stated otherwise, the above statements also apply to the second embodiment.

Fig. 4a shows again in turn a horizontal longitudinal section sketch. The conductor 2 has in this example a portion 24 which can be moved by the connection element 5 so that it separates from the remaining conductor 2 and thereby the two conductor end pieces 25, 26 are formed. As indicated in FIG. 4 a, the partial region 24 is preferably aligned transversely, in particular perpendicularly to the longitudinal axis L of the busbar 1. However, alternatively, a corresponding portion 24 may also be formed parallel to the longitudinal axis L.

The connection element 5 can advantageously be arranged correspondingly rotatable or displaceable.

Preferably, in this embodiment, the conductor 2 has a "staggered" structure, so that it extends with a plurality of sections 211 along a first straight line g1 and with several further sections 212 along a second straight line g2 parallel to the latter, wherein the portion 24 electrically connects one of the portions 211 to one of the further portions 212. The two mentioned straight lines g1, g2 preferably extend parallel to the longitudinal axis L.

Furthermore, preferably, the conductor 2 also has at least one further portion 24 ', which is designed in particular analogously to the first-mentioned portion 24. In the example shown in Fig. 4a, the plurality of sections 211 with the others are plural

Sections 212 through the portion 24 and the at least one further portion 24 'arranged alternately connected, so that a total of a meander-shaped conductor portion of the conductor 2 is formed, which extends parallel to the longitudinal axis L with its main extension.

It can further be provided that the portion 24 forms a "filler" or a component which is formed separately from the remaining conductor 2. In this way, the portion 24 is prepared, so to speak for a separation from the conductor 2; It can be achieved that the partial region 24 can be separated from the remaining conductor 2 without mechanical destruction. For electrical contact with the rest of the conductor 2, for example, resilient contact areas may be formed, which are symbolically indicated in Fig. 4a by small circles.

In Fig. 4b, a corresponding vertical sketch normal to the longitudinal axis L at the level of the portion 24 is shown, again with the to be connected to the busbar 1 light module 3. Fig. 4c shows the situation with the connected or mounted light module 3. Again, in the connected state, the original conductor 2 between the two Leiterendstücken 25, 26 is separated, as indicated in Fig. 4c by the two slashes; instead, the two conductor end pieces 25, 26 are connected via the LED light source 4 or the conductor section 6 with the LED light source 4 connected therein.

The said movement of the portion 24 may be realized, for example, by displacing, shifting or turning or pivoting. For example, it can thus be provided that the filler or the portion 24 is unscrewed or moved laterally.

In an embodiment with said further subregions 24 'can be achieved that the light module 3 can be mounted on any of the subregions 24, 24' to the busbar 1 and electrically connected, so that along the longitudinal axis L several possible connection points are formed for mounting the light module 3.

In the first-mentioned embodiment in which the section 21 is severed, there is basically no restriction with respect to the position along the longitudinal axis L at which the light-emitting module 3 is mounted on the bus bar 1. In contrast, in the second example, the possible mounting locations are defined by the transverse portions 24, 24 'of the conductor 2.

In the first example, when the lighting module 3 is dismantled, the conductor 2 is cut through in the busbar 1. In the second example, however, the design can advantageously be such that when the connection element 5 is separated from the electrical conductor 2, the two conductor end pieces 25, 26 are automatically electrically connected again, for example by a spring element. For example, it can be provided for this purpose that the sub-area 24 is moved back to its original position, so that the original course of the conductor 2 is restored. The light band system can thus continue to operate in this embodiment after disassembly of the light module 3 without further notice. In other words, a reversible arrangement of the light-emitting module 3 on the busbar 1 is made possible.

In both examples, the electrical conductor 2 preferably has a return line section 23 which extends along the longitudinal axis L of the busbar 1, wherein no light source, in particular no consumer is connected in the return line section 23.

Preferably, the constant current source 7 is arranged with respect to the longitudinal axis L at a first end portion of the conductor 2; At the corresponding opposite end region, the conductor 2 preferably has a connection section 23 which connects the section 21 or, in the case of the second example, a section in which the section 24 is located to the return section 23.
