Figures 17 to 21

In this sequence of figures, the assembly of one or more interconnected luminaire modules 1 in a channel 8 or freely on a support structure, such as in particular a building wall, is shown. Here, reference is also made to the applicant's earlier patent application DE 101 15 846 A1.

Figure 17

The channel 8, which is advantageously made of plastic, is in principle U-shaped in vertical cross section and has the base 80 and the two side walls 81 rising therefrom, which are continued in a wing 82 which is angled outwards. The wings 82 end in a thickening 83 . At the mouth of the side walls 81 in the bottom 80 there is an outer groove 805 , which is undercut by a nose 804 . On the inside, the base 80 has a longitudinal groove 800 in the middle and a clamping rail 801 with an undercut 802 on both sides thereof. Both clamping rails 801 and undercuts 802 face one another. A hollowed-out cable duct 803 is located at least between a clamping rail 801 and the adjacent side wall 81 .

Figure 18

In principle, the holding clip 19 is also U-shaped and has the central base 190 and the side webs 193 extending on both sides thereof, which merge into wings 195 which are angled outwards. There is an inwardly raised cam 194 on each of the side webs 193 . There is a centrally positioned hole 196 in the plate-like base 190 and a nose 191 protruding from its outer edge, which can be bent in an upright or horizontal position. Further lying tabs 192 are punched out of the base 190, two in the lateral outer areas extending outside open to below the base of the 190th

Figures 19A to 20B

When using the channel 8 , the holding clips 19 are placed with their base 190 on the two clamping rails 801 at the bottom 80 of the channel 8 in a somewhat transverse manner and are screwed into the undercuts 802 with their tabs 192 . Here, the downwardly curved nose 191 comes to lie transversely in the longitudinal groove 800 , so that the position of each holding clip 19 inserted is additionally stabilized beyond the friction and spring force between the tabs 192 and the clamping rails 801 . When a luminaire module 1 with the housing profile 18 is inserted, the cams 194 on the side webs 193 of the holding clamp 19 grip elastically via the retaining ribs 184 which are present on both sides and thereby fix the housing profile 18 which is introduced into the channel 8 and is the essential sheathing of the luminaire module 1 . The lighting module 1 can be equipped with simple tube holders 11, 11 ' and is thus equipped with a single fluorescent tube 10 (see FIGS. 6A, 14A, 20A). Alternatively, the luminaire module 1 is provided with double socket holders 12, 12 ' and thus in pairs socket sockets 120 , so that two fluorescent tubes 10 are used (see FIGS. 6C, 13A, 13B, 20B). To close the channel 8 , a channel cover 9 is provided, the plate part 90 of which spans the open side of the channel 8 . The enclosure 91 on both sides of the manhole cover 9 can be elastically snapped onto the thickenings 83 on the manhole 8 .

Figure 21

If you want to install a luminaire module 1 without the channel 8 , a required number of retaining clips 19 with their respective base 190 are attached to the building through the holes 196 . The tabs 192 and the nose 191 ' which is now just bent now have no function in themselves. A lamp module 1 with its housing profile 18 can be snapped in the same way onto the holding brackets 19 , for example screwed or doweled on, the cams 194 on the side webs 193 of the holding brackets 19 in turn elastically gripping the retaining ribs 184 of the housing profile 18 which are present on both sides.
