FIG. 1 shows a perspective view of the flush-fitting-device socket/mounting plate arrangement before assembly. It can be seen that the proposed flush-mounted LED lighting device consists of a flush-mounted appliance socket 3 , an additional mounting plate 10 and a lighting element, as follows in more detail from the description below. The flush-fitting appliance socket 1 has a connection unit for a 230 V power supply line, a converter (konverter) and a control/regulating device for controlling the converter. The converter feeds a luminous means 4 which is designed in the form of at least one LED arranged centrally on the front face of the appliance socket.

The concealed-installation socket 1 has a support plate (support ring) 5, which is provided in the usual form with edge-side locking holes 6 that are suitable for assembly and supports elastic supports (Federspreizen) for assembly, Among them, the spring support used for this purpose—actuating bolt 7—can be identified. In addition, the carrier plate is equipped with at least two receptacles 8 for plastic supports (see reference number 12 in FIGS. 2 and 3 ).

The mounting plate 10 equipped with a central recess 11 has on its back the already mentioned plastic support with a drilled hole 13 accessible from the front of the mounting plate 10, into which a support part (Spreizmittel) can be inserted. In the borehole, preferably the mounting screw 14 can be screwed into the borehole. Usually two oppositely arranged receptacles 8 /plastic supports with bores 13 are sufficient. Furthermore, the mounting plate 10 has on its front side a plurality of guide/stop devices 15 for fastening the luminous elements. In the exemplary embodiment shown, four symmetrically arranged guide/stop devices 15 are provided. Finally, markings 16 are placed on the front side of the mounting plate 10 on the edge side, which simplify the mounting of the luminous element on the mounting plate and indicate the position with which the luminous element can be placed on the mounting plate. assembly board.

FIGS. 2 and 3 show side views of the flush-mounted appliance socket/mounting plate arrangement to illustrate the type of fastening. Here according to Figure 2

- the plastic support 12 of the mounting plate 10 has been introduced into the receptacle 8 of the carrier plate 5 of the flush-fitting device socket 3 , and

- The mounting bolts 14 are introduced into the bores 13 of the plastic support 12 . According to FIG. 3 , the mounting bolt 14 is screwed completely into the borehole 13 , whereby the outer wall of the plastic support 12 is pressed against the edge of the receptacle 8 according to the generally known principle of pin joints (Duebel-Prinzip). This results in a desired fastening of the mounting plate 10 to the flush-fitting appliance socket 3 . FIGS. 2 and 3 additionally show a guide/stop device 15 arranged on the front side of the mounting plate 10 .

FIG. 4 shows a view of the front of the mounting plate, which has already been fastened to the flush-fitting device socket 3, on the one hand via the screwed-in mounting bolts 14 and on the other hand via the central recess 11. The lighting device 4 is identified. Furthermore, FIG. 4 shows four guide-stop devices 15 arranged in a symmetrical manner along the "covered" circle (see circle A indicated by a dotted line) and four guide-stop devices 15 also arranged in a symmetrical manner. Markings 16 on the edges of the mounting plate 10 which indicate the “angle of rotation” at which the luminous element is first placed on the mounting plate 10 . A predetermined angle of rotation (see arrow B) is then effected in order to fix the light-emitting element on the mounting plate 10 in this way.

FIG. 5 shows a rear view of a mounting plate with mounted luminous elements arranged behind it. First, the mounting plate 10 with its central recess 11 and the two oppositely arranged plastic supports 12 with their bores 13 are recognized. On the edge side, the lighting element 18 projects beyond the mounting plate 10 with its frame 21 . The illuminant of the luminous element 18 at the location of the central recess 11 preferably has a light entry surface 20 configured in the form of an optical lens. At the position of the guide/stop device 15, the mounting plate 10 has a window, so that the stop of the luminous element 18 or its frame 21, which works together with the guide/stop device 15 of the mounting plate 10, can be seen through the window. device 22.

6 and 7 show cross-sectional views of mounting plate/luminous element arrangements from different angles. In both cases it can be seen that the (for example pin-shaped) stop means 22 connected to the frame 21 of the light element 18 engages under the (for example hook-shaped) guide/stop means 15 of the mounting plate 10 (greifen), thereby causing the desired restraint. In FIG. 7 , additionally, illuminant 19 of luminous element 18 , which is formed, for example, in the form of an acrylic cube and is connected to frame 21 , can be seen.

FIGS. 8 and 9 show views of the mounting plate/luminous element arrangement in different embodiments of the luminous element. In each case, it is shown in which position, rotated relative to the mounting plate 10 , the luminous element 18 is mounted on the mounting plate 10 . This rotational position is clearly indicated by reference 16 . Lighting elements 18 of different designs can be mounted on the same mounting plate using the same flush-fitting device socket:

- construction of the illuminant 19 in the form of an acrylic body (Acrylkoerper) according to FIG.

- According to FIG. 9 , the illuminant 19 is surrounded by a frame 21 also in the assembled position when viewed from the outside. When the frame 21 is used, the recessed LED illuminant can be included/integrated in an aesthetically pleasing manner in the installation unit and/or the switch and socket unit.

The following outlines the assembly steps required when assembling a recessed-LED lighting unit:

1. Fitting of the concealed-equipment socket 3 in the concealed-equipment box using elastic supports and/or using fastening bolts which engage the carrier plate 5 through the locking holes-notches 6 .

2. Mounting the mounting plate 10 by introducing the plastic support 12 into the receptacle 8 and subsequently screwing the mounting bolts 14 into the drilled holes 13 (thus expanding the plastic support).

3. Place the luminous element 18 on the mounting plate 10 in a rotational manner taking into account the marking 16 and then turn the luminous element 18 into the end position, so that the guide/stop 15 /stop 22 engages in the bayonet Cooperate in the sense of Bajonett-Verschlusses. Expediently, a slight and releasable locking is effected by the guide/stop device 15 /stop device 22 in the end position.

For example, in order to replace a damaged luminaire 4 or a damaged converter, the removal of the recessed LED lighting device is carried out in the reverse order:

1. Rotate the luminous element 18 relative to the mounting plate 10 taking the markings 16 into account, and then remove the luminous element 18 from the mounting plate 10 .

2. Unscrew the mounting bolts 14 (thus loosening the plastic support 12 again), and then remove the mounting plate 10 from the carrier plate 5 .

3. If necessary, remove the concealed-equipment socket 3 from the concealed-equipment box by resetting the elastic support and/or by unscrewing the fastening bolt engaged with the locking hole-notch.

FIG. 10 shows a perspective view of the assembly plate/luminous element arrangement before assembly. It is envisaged here that a flush-fitting box is installed in the ceiling 25 and that the flush-fitting socket 3 is fitted in the flush-fitting box. Furthermore, it is conceivable to mount the mounting plate 10 on the carrier plate 5 of the flush-mounted appliance socket in the manner described above.
