For example, the support profile 2 be provided for the operation of the busbar system oriented so that the cross section is open at the bottom. However, this is purely exemplary and represents no restriction, because the support profile according to the invention 2 is suitable for use in any orientation against gravity. For the sake of simpler description, the following is an orientation of the supporting profile 2 assumed that the first direction u points vertically down. With other orientation of the support profile 2 the following directions must be reinterpreted accordingly.

In particular, it can be provided that the lighting module 3 such on the mounting rail 2 is held so that it passes through the open area of the cross section down from the mounting rail 2 outstanding or in total below the mounting rail 2 is arranged.

The light module 3 may include a light source, such as an approximately tubular light source, wherein for the arrangement of the light module 3 on the support profile 2 is provided that the longitudinal axis of the light source to the main axis of the support profile 2 is parallel. It can therefore be provided, for example, that - as in 3 indicated - the light module 3 with a longitudinal direction of the mounting rail 2 arranged in parallel tubular light source at the bottom of the support profile 2 is arranged.

Especially can be provided that the busbar system for recording of several similar or identical lighting modules of the mentioned Art is provided, the lighting modules in particular either each having a certain distance from each other or else can be provided immediately adjacent to each other.

It is provided that of the light module 3 generated light at least substantially downwards, ie in the first direction, is discharged. This results in the illustrated arrangement of the light module 3 opposite the support profile 2 more or less by itself. By "essentially" be said that the light module 3 at least designed to emit light in the lower half-space. In particular, the lighting module 3 be provided for generating a direct lighting.

Furthermore, it can be provided that the support profile 2 is arranged for operation of the busbar system in a room with a ceiling such that it has a distance from the ceiling, so it is arranged, for example, suspended from the ceiling.

To generate a light output in a second, opposite to the first direction direction o - here so up - has the busbar system, a lighting element 4 with a light source 6 on. For example, the lighting element 4 be designed to produce an indirect lighting over the ceiling.

The supporting profile 2 has on one side, which points in the second direction o, here upwards, an opening 10 on, through which the light source 6 of the luminous element 4 and / or one of the light source 6 associated optical element 8th extends.

By this arrangement, the lighting element 4 as it were in the supporting profile 2 or - in cross-section - in the profile profile of the support profile 2 to get integrated. So it can save space as a quasi-integral part of the support profile 4 be educated.

At the opening 10 it can be a breakthrough opening through the support profile 2 act. With reference to the shape of the opening 10 can be provided that their extension in the longitudinal direction of the support rail 2 is about the same size, for example, maximum twice as large as their extension in the transverse direction to it. Thus, for example, a circular or square-shaped opening may be provided.

If it is provided that the mounting rail 2 is hung for the arrangement of the opening 10 within the mounting rail 2 is advantageously provided that the point of attack or the points of attack for the suspension on the one hand and the opening 10 on the other hand, in different longitudinal areas of the mounting rail 2 are arranged.
