Such ceiling lights should bring to the one hand a pleasant visual appearance for the viewer with it, on the other hand to ensure the most pleasant illumination of a room. In the prior art, both ceiling lights are known, which ensure only a direct irradiation, ie when mounted on a ceiling, a light emission away from the ceiling, as well as ceiling lights that ensure both direct and indirect lighting, ie lighting on the one hand from the ceiling away and on the other hand towards the ceiling. The direct lighting is particularly advantageous for a workplace lighting, the indirect lighting for a background illumination of a room. Generic ceiling lights are usually attached to a ceiling so that they point with their vertical top to the ceiling and extend horizontally along the horizontal. Usually, the ceiling lights have it a horizontally extending horizontal light exit window over which they emit light.

In FIG. 1 comprising the FIGS. 1a, 1b . 1c, 1d and 1e are in different schematic schematic diagrams different views on sections of a luminaire module 1 of a system according to the invention or of some of his Elements represented. From the synopsis of FIGS. 1a, 1b . 1c and 1d the basic structure of each luminaire module 1 of the described embodiment of a system according to the invention can be seen. Such a luminaire module 1 has two elongate profiles 10 which are elongated in a longitudinal direction X and which are interconnected by two transverse connectors 11 extending in a transverse direction Y. The design of the longitudinal profiles 10 and the cross connector 11 is in particular from the Figures 1c and 1d recognizable. The longitudinal profiles 10 each have an identical cross-section perpendicular to the longitudinal direction X and in the present case are produced by extrusion from aluminum. The cross connector 11 are made of a metal sheet by means of cutting and forming process. The cross connector 11 are each formed identically. The longitudinal profiles 10 each form a cavity 100, which extends in the longitudinal direction X over the entire longitudinal extent of the longitudinal profiles 10 away. In the cavity an above-explained, accessible from each longitudinal end of longitudinal guide is formed. As from the synopsis of FIGS. 1a, 1b and 1c As can be seen, the longitudinal profiles 10 have side wall sections with which they delimit the cavity 100, wherein these side wall sections form outer sides of the luminaire modules 1 perpendicular to the longitudinal direction X. In the present embodiment, the cavity 100 is completely enclosed circumferentially around the longitudinal direction X, wherein a further side wall is provided, which does not form an outer side of the luminaire module 1 but faces the longitudinal profile 10 opposite in the transverse direction Y. The longitudinal profiles 10 furthermore have a guide 101, which in the present case is designed as a groove which has an undercut on its upper side, wherein a fastening element, to which a cable is fastened, can be held reliably in the guide 101. How out Figure 1c can be seen, this formed as a groove with undercut guide 101 in an end portion of the longitudinal profile 10th interrupted, whereby an insertion region is formed, via which the fastening element, which may be formed, for example in the manner of a ball or a cylinder with a round base, can be introduced when the longitudinal profile 10, as in the FIGS. 1a and 1b can be seen, connected to another longitudinal profile 10 via cross connector 11 and is integrated into a lamp module 1. The cross connectors 10 each have a cross section perpendicular to the transverse direction Y in the manner of an L. This cross section, the cross connector 11 each over more than 70% of their extension length in the transverse direction Y on. The cross connectors 11 each have a clamping device 110 for a PE contact. By way of this, the housing of the luminaire module 1, which is essentially formed by the longitudinal profiles 10 and the transverse connectors 11, can be connected in a simple manner to a protective conductor, which is generally advantageous in accordance with the invention. In the present embodiment, the cross connectors 11 are formed of a metal sheet. In Figure 1e is a section of a light module - 1 overlooking its first. For the sake of simplicity, only the first optical element 12 forming a lower side section of the luminaire module 1 is shown in the illustration, but not the second optical element 15 forming an upper side section of the luminaire module 1, which, for example, in FIGS FIGS. 3b . 4b and 4d is shown. In the described embodiment according to the invention, all the luminaire modules 1 are designed to provide direct and indirect illumination. The direct illumination is effected by the emission of light through a light exit window, which is formed by the first optical element 12, the indirect illumination is effected by light emission through a light exit window, which is formed by the second optical element 15.

The light sources 13 are each in the form of an LED chain elongated in the longitudinal direction X, each of the light sources 13 being arranged on one side of one of the longitudinal profiles 10 which delimit the receiving space and which faces the other longitudinal profile 10, which is generally advantageous in accordance with the invention. It will be apparent to those skilled in the art that as a result a high light emission intensity can be provided by the lamp modules 1 at a very low height along the vertical direction Z and that due to the arrangement of the LEDs on the said sides of the longitudinal profiles 10 a good light mixing in the receiving space can be done and Thus, a homogeneous light emission via the optical elements 12, 15 can be ensured. Out Figure 1e It can further be seen that an electrical plug-in device 14 is provided at the first longitudinal end of the luminaire module 1, which is held within the cavity 100 of one of the longitudinal profiles 10 at a longitudinal end portion of the longitudinal profile 10 and from the longitudinal end of the longitudinal profile 10 and thus from the first longitudinal end of the lamp module 1 is accessible.
