Since the spacers 24 project beyond the lamp frame 3, it is possible to accommodate the connection cables for power supply and control of the individual surface lighting modules in wall mounting behind the surface lighting modules and thus behind the lighting device not visible from the outside.

At the raised portion 22 of the rear wall 21, a receiving and guiding plate 5 is preferably arranged with a handle 50 made of plastic, which has two lateral guide rails 51, which arranged opposite the handle 50 ends form an insertion opening 53. Centered in front of the insertion opening 53, a locking element 15 is arranged in the form of a resilient pressure piece. Task and function of the receiving and guiding plate 5 and the locking element 15 will be explained in more detail with reference to FIGS. 8 and 9.

8 shows a schematic perspective view of the rear side and FIG. 9 shows a side view of a surface light module as described above with reference to FIGS. 4 to 7.

In the receptacle of the guide plate 5, a fastening element 8 is inserted, which consists of a mounting plate 80, a connecting body connected to the mounting plate 80 81, a pivotable pin 82 and a clamping element 83 consists. The mounting plate 80 is placed on the locking element for connection to the receiving and guide plate 5 and pushes this preferably designed as a resilient pressure piece locking element 15 when inserted into the lateral guide rails 51 of the receiving and guide plate 5 down. If the fastening element 8 is completely inserted into the receiving and guiding plate 5, then the resilient pressure piece 15 engages in an opening of the fastening plate 80 or, as shown in the embodiment according to FIG. 8, lies against an outer edge of the fastening plate 80.

In the position of the lever 73 shown in FIG. 12, which corresponds to the position shown in FIG. 11, the abutment piece 72 is attracted to the end of the hollow cylindrical connecting body 70 so that the groove formed between the abutment piece and the end of the hollow cylindrical connecting body 70 74 is reduced and thus the elastic ring 75 is widened. A boundary is thereby created between the widened elastic ring 75 and the abutment shoulder 71, which connects the lamp frames 3a and 3b of the area light modules 1a, 1b to one another according to the illustration according to FIG.

By folding the lever 73 in a position which is in the extension of the cylindrical connecting body 70 as shown in FIG. 10, the groove 74 is widened, thus canceling the expansion of the elastic ring 75. Since the outer diameter of the hollow cylindrical connecting body 70 and the outer diameter of the relaxed elastic ring 75 are smaller than the diameter of the mounting holes 30 in the legs of the lamp frames, the lateral connector 7 can be formed by the aligned mounting holes 30 of the lamp frames 3a, 3b of the surface lamp modules 1a to be connected together , 1b are inserted as shown in FIG.

After the insertion of the lateral connector 7 through the mutually aligned mounting holes 30 of the lamp frame 3a, 3b, the lever 73 is pivoted to the position shown in FIGS. 11 and 12, in which the contact piece 72 is tightened and thus the elastic ring 75 is widened. By a corresponding length adjustment between the end faces of the lamp frame to be connected together 3 a, 3 b and the length of the distance between the expanded elastic ring 75 and the contact shoulder 71 is a fixed positive locking connection between the lamp frame 3a, 3b produced in accordance with FIG. 11.

As an alternative to a connection of the lamp frames 3a, 3b by means of a lateral connector, a firm positive and non-positive connection can be produced by means of screws and nuts, which is advantageous in particular for a solid wall or ceiling mounting of the lighting device.

Further alternatives are bayonet locking connections between the individual lamp frames or by a corresponding profiling of the outer sides of the lamp frame by means of dovetail connections.

For light control, the lamp frame 3 of the surface light modules 1 according to FIGS. 13 and 14 can additionally be connected to a movable accessory frame 9 for accommodating filter disks, color filters, blinds and the like. The connection takes place via a plug-in or hinge connection 90 at one of the front ends of the lamp frame 3 and via a hinged hinge 91 and a securing element 92. FIG. 13 shows the accessory frame 9 in an applied, secured position, while FIG. 14 shows a side view of the lamp frame 3 with an accessory frame 9 in the folded position shows, so that an easy replacement example of filter discs, color changer, lenses or color foils is possible.

As an alternative to the connection of a plurality of each composed of a lamp housing and a lamp frame surface lighting modules can be summarized as a result of the composition of the surface lighting modules of lamp frame and lamp housing and a plurality of light housing over and / or next to each other in a lamp housing enclosing all the light frame to a large-scale lighting device. A possible variant is shown in FIG. 15 and should be explained in more detail below.

The electrical connection of the lamp housing 2a to 2d takes place in the manner described above on the rear wall of the lamp housing 2a to 2d laid control and power supply cable. The four superposed luminaire housing 2a to 2d are laterally and with respect to the top and lowest luminaire housing 2a and 2d also connected at one end face to the lamp frame 3c in the manner described above. The joints formed between the luminaire housings 2a to 2d can be closed with a permanently elastic plastic, for example silicone. Alternatively, the connection is possible via suitable elastic intermediate pieces or via webs, which are laterally connected to the lamp frame 3c and in which the lamp housing 2a to 2d can be used analogously to the compound shown in Fig. 16.

To connect a single surface lighting module or one composed of a plurality of surface light modules described above lighting device with a tripod or a wall or ceiling mounting can be described in addition to the above described with reference to Figures 8 and 9 connection type Ober the rear wall of the surface lighting modules designed as a holding bracket 6 according to Fig. 16 are provided, which is connected to form or traction elements 37, 38 on the side legs of the lamp frame 3. The connection takes place via at the ends of the retaining bracket arms 64, 64 'of the retaining clip 6 provided Gegenformschlusselemente or counter-force closure elements 63, 63', which engage in the form or adhesion elements 37, 38 of the lamp frame 3.

In this case, the connection can be made either over the short or long axis of the surface lighting module, since the headband 6 of FIG. 22 is variable in length, so that the temple ends can be adjusted to different distances to each other. For this purpose, the headband arms 64,64 'are inserted into a headband middle piece 65, which has two elongated holes 67, in which with the headband arms 64, 64' connected thumbscrews 66 are inserted. By loosening the wing screws 66, the headband arms 64, 64 'within the headband center piece 65 can be moved and thereby the distance of the ends of the headband arms 64, 64' are set to each other.

The headband center piece 65 is connected to a connection sleeve or connecting pin 68 which can be inserted into a wall, ceiling or tripod mounting. The lighting device connected to the retaining clip 6 or the surface lighting module connected to the retaining clip 6 can thus be pivoted as desired about the axis formed by the counter-form-locking elements or counter-force-locking elements 63, 63 'of the retaining clip 6.
