By providing and the interposition of the adapter module between mounting rail, operating device and light module, the individual modules of the lighting device can be combined with each other and interchangeable. No matter which module is to be used, this can be connected or replaced by selecting a corresponding adapter module in the manner of a modular principle with the other module components to build a desired light. By means of the adapter module, the invention thus provides a particularly variable modular illumination device comprising a plurality of connectable modules with which the illumination device can be easily and quickly adapted to new visual tasks and / or to new standards by assembling these modules, the illumination device or by its replacement.

This is preferably done as far as possible or completely without tools and without the involvement of specialized personnel, so only through the use of mutually connectable modules for adaptation or realization of the respective visual task.

The preferred embodiment provides that the primary-side mounting rail interface of the adapter module within the adapter module to a primary-side adapter interface for the operating device is guided and after the conversion in the operating device is separated from the primary side secondary side of the adapter interfaces with the light module interface of the adapter module is connected.

The interfaces may, in addition to the current transmission, also be designed for data transmission of control data, e.g. be designed to connect a DALI control line.

The connection is made particularly simple if the interfaces comprise connectors which can be connected to one another essentially by carrying out a simple translatory movement. These plug connectors preferably comprise a first, receiving plug part, which is provided on a first joining partner, and a second plug part, which can be inserted into this second plug part, which is provided on the second joining part, being complementary to the first plug part.

The assembly is further simplified if the connectors simultaneously connect for the primary-side high voltage of e.g. 220 volts AC and the secondary side low voltage voltage of e.g. 30 volts DC, so do not need to connect multiple connectors for the primary and secondary connections.

To better realize a seal against media entry between the modules, the plugs are in particular designed so that they are hidden in the installed position by the modules or their housing. A Schutzartkonforme connection can also be achieved in that sealing elements are provided between the connector parts. These may include, for example, ring seals.

In the simplest case, the seal is a ring seal, which is inserted into the collar surrounding the plug contacts, for example, on the connecting part, and which is dimensioned so that after insertion of the connector receptacle in the collar, a sealing interference fit arises. To prevent inadvertent displacement of the ring seal, this can be inserted into a groove in the interior of the collar or on the circumference of the connector receptacle.

Alternatively, the seal may also be formed as a lip seal. Another alternative is a plug-in seal which can be inserted, for example, as a matching block in the collar of the plug and having openings for the plug contacts. It may happen that the connection system has fewer plug contacts and corresponding plug receptacles than are possible at maximum. For this case, the openings of the block seal Versatile used this block seal is first closed by piercing lips, which are pierced when connecting only from the existing plug contacts.

Further advantages of the invention are that the lighting systems can be assembled from a small number of standardized components or assemblies, the independent operation of the individual lighting modules is still possible. For example, the connection part and the device part can be produced in each case in a uniform shape for light bands of different sizes, for example different depths of the profile, and only the connecting part can be individually adapted to the specific embodiment. This results in a cost reduction for the production and stockpiling of components.

The primary-side mounting rail interface between the mounting rail 2 and adapter module 4 in the present case comprises at least one front end 4A of the adapter module 4, into which an insertion plug 34 can be inserted on the inside, which is provided with a circumferential annular flange, which rests on the inside of the edge of the end openings 4A and their connections then protrude through the end openings 4A of the adapter module 4 to the outside. On this plug-in connector 34, a flat plug 16 is plugged using a sealing ring 20, which has a substantially L-shaped configuration with a lower and shorter transverse limb for electrical connection to the plug connector 34 and a longer and transversely to the transverse leg extending longitudinal leg, the on a socket 2G on the underside of the horizontal leg 2C of the support rail 2, and also with the interposition of a sealing ring 22 attachable and thus connectable to this. In this way, therefore, the desired IP protection is realized, in this case z. B. an IP65 with a complete contact protection against Dust deposition from inside as well as jet water.

The turn oblong box-shaped housing of the operating device 5 is provided for receiving mounting in the adapter module 4 at its ends with dovetail projections 5A, 5B, which are inserted into correspondingly formed and preferably releasably insertable dovetail holder 30, 32 from below, to the operating device 5 thus receiving in to attach the adapter module 4 and connect to this.

The plate-shaped, rectangular LED lighting modules 6, 8 have on the tops of each plug 6A, 8A, which pass through openings in a plate seal 28 and are electrically connected in installation position with the lower ends of connecting parts 24, 26 and thus a 2-channel, form the secondary-side light module interface. In this respect, the connecting parts 24, 26 carry both the primary-side high-voltage current of e.g. 230 volt alternating current as well as secondary low-voltage current of e.g. 30 volts DC.

In an alternative embodiment, in each case only one connecting part 24, 26 may be electrically connected, wherein the respective other, opposite connecting part only serves for the mechanical fastening of the operating device 5 to the adapter module 4.

In the direction of radiation in front of the LED modules 6, 8 are attached as consisting of transparent plastic optical modules 10, 12 which bundle or direct the light flux generated by the LED lighting modules.

This in FIG. 3 shown light strip 101 includes a support rail with a bottom part 103 and side parts 102. On the bottom part is the through-wiring 104, in this case a seven-pin ribbon cable. In the space between the side parts 102 of the adapter module 140 can be used, which has an end wall 141 with an opening 142. He wears the operating equipment and the lighting module 143. The end wall 141 of the adapter module 140 is accessible via a cavity 144 from the inside. To protect the light module, the cover 150 is provided. The grid 160 serves to guide or glare the emerging light.

The connection system according to the invention comprises the connection part 110, the connection part 120 and the device part 130. The connection part 110 is held with corresponding grooves by means of the beads 106 in the side parts 102 of the support rail 101 and comprises the through-wiring 104, with its side walls 112 a tight connection to the through-wiring 104 form. The connection part 110 has a recess 111 into which the collar 125 of the connection part 120 can be inserted. In this insertion, the protruding inside the collar 125 of the connecting part pins 123 are guided through the guide openings 115 in the inner projection 116 so that they can penetrate with their cutting 124, the insulation of the individual wires of the through-wiring 104 and contact the conductors in contact. To seal the gap between the collar 125 and the connector 110, a lip seal 114 is inserted into the collar 125.

For installation, the device part 130 can be moved through the cavity 144 in the adapter module 140, so that finally the projection 31 passes through the opening 142 to the outside. Now you can insert the lip seal 133 in the collar 126 and push the whole over the projection 131. In this case, the seal 133 enters the circumferential groove 134 on the projection 131. Again, a solid frictional connection of the two parts is made.

FIG. 4 shows details of a modified embodiment, also in exploded view. The connecting part 120 is shown here with the built-in contact pins 123. Again, a collar 126 is attached to the second portion 122 of the connecting part 120. In this, the block seal 136 can be inserted, having openings 137 through which the ends of the contact pins 123 can pass. The device part 130 can in turn be applied to the inside of the end wall 141 of the adapter module 140 such that the projection 131 protrudes through the opening 142 to the outside. Now, the connecting part 120 can be placed with the collar 126 on the projection 131 of the device part 130, wherein the attachment takes place in this case by releasable latching means not shown here. By means of the plug receptacles 138 in the device part 130, the operating devices in the adapter module 140 can be connected.

Another embodiment of the light band according to the invention shows FIG. 5 , The mounting rail of the light strip 101 has a bottom part 103 and side parts 102. On the bottom part 103 is the through-wiring 104, again in the form of a seven-pin ribbon cable. Again, the connector 110 is attached by means of the beads 106. It has a recess 111 in which a projection 116 rises, in which the plug receptacles or guide openings 115 are attached, which are individually connected by means not shown here with the conductors of the through-wiring. The O-ring seal 114 can be inserted into the collar 125 of the connecting part 120, whereafter the collar 125 is guided into the recess 111 and over the projection 116. To fix the O-ring may be present on the outside of the projection 116 and / or inside the collar 125, a circumferential groove. The device part 130 is designed similar to the part 30 in the first embodiment, however, an O-ring seal for sealing between the connecting part 120 device part 130 is also provided here.

The Figures 6a, 6b and 6c show details of a suitable for the execution of the opening adapter module. In FIG. 6a a part of the adapter module 204 is shown as an approximately U-shaped profile in a view opposite to the light exit direction.

A first connector 222 provided with a five-pole socket engages the wiring with its base, the sockets making contact with the wires. A second terminal part 224 also surrounds the wiring 203 and has five sockets that are equally in contact with the wires. In the second connection part 224 one end of a control device 205 is inserted with five plug contacts. The other end of the operating device 205 is also plugged into the sockets of another second connection part 224 (not shown here). These two connection parts 222, 224 thus realize the additional interfaces contained in the adapter module. The plug contacts are frictionally engaged and / or fixed by a latching mechanism in the sockets of the second connection parts, so that the operating device 205 can not fall out when the opening of the U-shaped adapter module 204 in installation position facing down. Two lighting modules 210, which are provided on its underside with a five-pin plug 222, are inserted with this in the sockets of the first connection part 222 and are aligned by means of cams 212 on the sides of the operating device 205 and frictionally held. This is in FIG. 6b illustrates which the arrangement without the U-profile of the adapter module 204, which would hide the view here, from above, ie in the direction of light emission represents. FIG. 6c shows details of the connection of the operating device 205 with the second connection part 224. The second connection part has passages 226 for the wiring. With the locking cams 231, it can be set in corresponding grooves on the inside of the adapter module 204. The sockets 225 receive corresponding contact pins of the operating device 205. The second connection part 224 comprises 2 rows of sockets 225, so that the operating device 205 can also be connected from the other side, if there is no first one Connector 222 is present. With a necessary conversion of the light band you can now depending on the desired result completely flexible only the lighting modules, lighting modules and operating equipment or even the whole adapter module replace.
