the installation housing
on the foundation, make sure that the installation housing in the grid of the plates
otherwise the plates will not be laid later.
In-ground luminaires of the conventional ones just described
There is no mechanical connection between the installation housing and
the flooring. Lowers the flooring, for example, due
of setting processes,
so the light can not follow this movement and then turns off
sticking out of the floor covering. On the one hand, this can lead to an undesirable stumbling hazard
On the other hand, a protruding from the floor lamp when rolling over

already known a lamp for installation in a niche in a side wall of a swimming pool. This luminaire has a conical luminaire housing which extends into the wall niche and has an annular fastening element with a hook. In the wall niche, a projection or an undercut is provided. The hook of the fastener engages behind the projection in the wall niche. On the opposite side of the projection of the lamp housing a wedge with two arms and a rotatably mounted in the arms bolt is provided. The bolt has an internal thread through which a screw is passed. About this screw, the bolt and thus the wedge, be moved in the longitudinal direction of the housing. Furthermore, the wedge can be rotated by 90 ° about the bolt, whereby the thickness of the wedge is changed. This makes it possible to adapt the wedge to the installation conditions in the niche. When the luminaire is installed, the wedge clamps the luminaire housing in the niche or behind it Head Start. Since the niche must have a projection, in this case, the construction of the niche is complicated. In addition, the installation of the lamp housing is difficult because the hook must be brought into engagement with the projection.
Furthermore, from the DE 44 16 538 C2
a luminaire for installation in a thin wall or in a cavity in a wall known. The luminaire has a housing, whose side walls extend into the wall opening, and on which anchoring elements are provided. Each of the anchoring elements has a stop flank which engages in or behind the wall and holds the lamp in the wall opening or behind the thin wall. Since this luminaire is a recessed wall luminaire, it is not exposed to great stress. The anchoring elements are therefore designed as triangular plates.

Below are embodiments of
Invention explained in more detail with reference to a drawing. Show it:
1 Sectional view of the recessed floor luminaire in the mounted state,
2 Perspective view of a floor light and
3 In-ground luminaire in bottom view.
1 shows a section through a retractable recessed ground light 1 in the assembled state. The recessed floor light 1 includes a luminaire housing 2 in which a reflector 3 with a lamp 4 is arranged. Furthermore, the required electrical components are in the luminaire housing 2 ,
The luminaire housing 2 gets into an undercut-free cavity 5 in the floor or in the floor plate 6 built-in. The bottom plate 6 For example, it can be cast from concrete or consist of installed natural or artificial stone slabs. Because of the cavity 5 for installation of the luminaire housing 2 has no undercuts or projections, it can be easily manufactured. Has the luminaire housing 2 the recessed floor light 1 a substantially cylindrical shape, so can the cavity 5 in the bottom plate 6 relatively easy to be made by a core hole.
The luminaire housing 2 indicates at its, the soil surface 7 facing the end of a flange 8th on. The flange 8th is preferably circumferential and serves as a stop when the lamp housing 2 in the cavity 5 is used. In the assembled state of the recessed ground light 1 is the flange 8th of the luminaire housing 2 on the soil surface 7 on. The flange 8th still has a level 9 on that in the cavity 5 protrudes. This level 9 serves as a bearing surface for a sealing ring 10 , In the sealing ring 10 is the edge of a glass pane 11 taken, which is the light exit opening of the lamp housing 2 covered. The sealing ring 10 and the glass pane 11 be over a cover ring 12 at the stage 9 of the circumferential edge or flange 8th of the luminaire housing 2 attached. This attachment can, for example, with screws 13 respectively.
To the luminaire housing 2 in the cavity 5 the bottom plate 6 to attach, indicates the recessed ground light 1 at least one clamping block 14 and at least one lead up. The clamp stone 14 is essentially wedge-shaped and is at its back 19 on one on the lamp housing 2 arranged reinforced slideway 15 guided. The opposite side 20 of the clamping block 14 is in the mounted state on the wall of the cavity 5 at. The clamp stone 14 also has an internal thread in which a threaded rod 16 is arranged. By turning the threaded rod 16 can the clamp stone 14 along the reinforced slideway 15 to be moved. The reinforced slideway 15 runs obliquely so that the distance between the reinforced slideway 15 and an opposite wall portion of the cavity 5 at the bottom surface 7 facing upper end of the lamp housing 2 smaller than the distance between the reinforced slideway 15 and the opposite wall portion of the cavity 5 at the bottom of the ground 7 remote from the lower end of the lamp housing 2 , Is the terminal block 14 in a lower position, that is on the ground surface 7 remote from the lower end of the reinforced slideway 15 so is the terminal block 14 spaced from the opposite wall portion of the cavity 5 arranged. The luminaire housing 2 can then in the cavity 5 to be moved. In an upper position, in which the clamping block 14 near the upper end of the reinforced slideway 15 is arranged, is the terminal block 14 frictionally engaged with the opposite wall portion of the cavity 5 connected.
The upper end of the threaded rod 16 will be in a cut 17 articulated in the step 9 guided, so the threaded rod 16 can be easily turned when the sealing ring 10 , the glass pane 11 and the cover edge 12 not mounted yet. Furthermore, the reinforced slideway 15 a second tour 18 for the threaded rod 16 on. The reinforced slideway 15 can on the lamp housing 2 to be appropriate. It is also possible to use the reinforced slideway 15 in the luminaire housing 2 to integrate.
In 2 is a perspective top view of a recessed floor light 1 shown. In this embodiment, the at least one projection for fixing the lamp housing 2 in the cavity also as a sliding clamping block 14 formed on a reinforced slideway 15 is guided. The clamps 14 are hollow bodies, with the sidewalls of the clamping blocks 14 are broken through and the bearing surfaces 19 . 20 on the reinforced slideways 15 and the wall of the cavity 5 are executed over the entire surface. The threaded rods 16 are arranged so that they are parallel to the reinforced slideways 15 run. The bearing surface 19 of the clamps 14 on the reinforced slideway 15 is also parallel to the threaded rod 16 and the slideway 15 , the bearing surface 20 of the clamps 14 that stick to the wall of the cavity 5 is present, is inclined and closes an angle to the support surface 19 one. The clamp (s) 14 are thus wedge-shaped, with the tip of the wedge to the ground surface 7 or to the flange 8th shows. Here is the length of the or the clamping block 14 bigger than its width.
In 3 is the recessed floor light 1 shown in view from the back of the case. In this embodiment, the recessed ground light 1 three evenly over the circumference of the lamp housing 2 arranged clamping blocks 14 for fastening the luminaire housing 2 in the cavity 5 on. As already in the 1 and 2 shown, is the cross section of the lamp housing 2 over the length of the luminaire housing 2 essentially constant. The slides 15 close with the luminaire housing 2 an angle. It would also be conceivable that the side wall or the side walls of the lamp housing 2 obliquely so that the cross section of the lamp housing 2 at its lower end is smaller than the cross section of the lamp housing 2 at its upper end.
The following is the installation of a recessed ground light 1 in a cavity 5 a floor plate 6 explained. Before installing the recessed ground light 1 in the cavity 5 become the or the clamping blocks 14 brought into the mounting position. In the mounting position are the clamping blocks 14 at the bottom of the ground 7 opposite lower end of the slide 15 , The clamps 14 thus stand behind the cross section of the step 9 of the luminaire housing 2 back, leaving the luminaire housing 2 easily into the cavity 5 can be used. The sealing ring 10 , the glass pane 11 and the cover ring 12 are not yet on the lamp housing 2 attached so that the threaded rod (s) 16 are easily accessible and can be rotated. Is the luminaire housing 2 in the cavity 5 used, then the threaded rod (s) 16 rotated and the or the clamping blocks 14 towards the soil surface 7 emotional. This results in a jamming of the housing 2 in the cavity 5 , Preferably, the coefficient of friction between the clamping blocks 14 and the reinforced slideways 15 less than the coefficient of friction between the clamping blocks 14 and the wall of the cavity 5 , This ensures that the frictional force between the wall of the cavity 5 and the clamping blocks is greater than the frictional force between the reinforced slideways 15 and the clamps 14 , Now lie the clamps 14 firmly on the wall of the housing 5 on, so by further Dre hen the threaded rods 16 the housing 2 deeper into the cavity 5 pulled until the circumferential flange 8th firmly on the ground surface 7 rests. Is the case 2 stuck in the cavity 5 jammed, so the sealing ring 10 with the glass pane in it 11 to the stage 9 of the luminaire housing 2 fitted and with the cover ring 12 fixed in the luminaire housing. By removing the cover ring 2 , the glass pane 11 and the sealing ring 10 is a easy replacement of the lamp 4 in the recessed floor light 1 possible. By using wedge-shaped clamping blocks 14 can the recessed floor light 1 take high loads.
