DE 37 39 076 A1 shows a recessed luminaire of the first type described, in which the recessed luminaire is always mounted on a component having a built-in opening. In contrast, DE 39 32 881 C2 describes a recessed luminaire which is fixed by means of a wire to a ceiling layer arranged over a corresponding intermediate ceiling.

There are more requirements for recessed luminaires. On the one hand, it is a typical mass product whose individual components are to be simple and of an economically advantageous design, so that the recessed luminaire is to be economically advantageous as a whole. Therefore, an effort is made to provide a material-saving design and a low weight, which is to facilitate

- 2 transport and assembly. Furthermore, the installation of the recessed luminaire into the recess is associated with considerable costs, since the recessed luminaire is assembled in the area of the recess and the recess is generally difficult to access, i.e. from a ladder, so that the recess is difficult and time consuming. In addition, a safe installation must be ensured, so that the fastening must be reliably secured even after many years.

A large number of different designs of recessed luminaires have already been developed. U.S. Pat. No. 2,939,669 discloses a suspension device for a recessed luminaire comprising a bridging support having a reflector screwed on its underside. The bridging device has a central support portion which is transverse to the reflector and which is connected at its ends to one support leg in the form of a support angle, the free end of which is adapted to support the ceiling comprising a built-in opening. The support part and the support legs are adjustable transversely to the longitudinal insertion hole by means of the adjusting device and can be fixed in the corresponding adjustment position. Retaining means for holding at least one bulb and for supplying power are not disclosed in this specification.

U.S. Pat. No. 3,388,247 discloses a recessed luminaire in the form of a longitudinal tubular luminaire having two end-cap-shaped base portions with short upper angles through which a vertically arranged screw extends, each having a head arranged underneath as an engagement element for the tool designed for its rotation, the bolts are provided near adjacent edges of the built-in opening. In addition, a reflector is provided. On each screw there is a clamping part with a clamping arm that projects over the edge of the hole. By rotating the bolts through the bore in the reflector through the bottom-mounted pivot element, it is possible to tighten the clamping parts against the ceiling. Apparently the reflector is held exclusively by the lower heads of the screws. Other measures for fixing the reflector are not described.

EP 0 499 044 A1 shows a ceiling recessed luminaire having a retaining means in the form of an embedded hole of a pot-shaped base part, a circular cylindrical hollow body with a diffusing disc in its lower region and a halogen reflector bulb in its hollow body. In order to hold the recessed luminaire in the built-in space, mounting means are provided, which consist of retaining springs with two arms each, one arm abutting the opening edge and the other arm abutting the ceiling. In this known arrangement, the retaining means must be designed such that, when the base part is inserted, it automatically snaps into its fastening position and therefore must fit precisely. Also, no manipulation of the retaining means from the interior space of the base part is possible since the base part is pot-shaped. Access to the halogen reflector bulb is also difficult because first the hollow body fixation must be released and the hollow body must be removed downward to allow access to the halogen reflector bulb.

The essence of the invention

SUMMARY OF THE INVENTION It is an object of the invention to provide a recessed luminaire in such a way as to simplify its installation and assembly and / or improve its accessibility.

The object is solved by a recessed luminaire, characterized in that the clamping means are releasably connected to the mounting means in such a way that they can only perform a limited movement path between the operating position and the mounting position or have mounting means for its mounting. fastening in a built-in opening, the base part preferably of flat or low construction, preferably on the rear side of the base part arranged means for electric current connection and possibly also for the lamp carriage, provided on the base side with means for holding at least one bulb; for its power supply, one or more supporting parts which are connected to the mounting means and on whose front side the base part is arranged and releasably held by means of the coupling device, and the means for influencing the light. button which are connected to a further ÚSTR it releasably held in the recessed luminaire.

The arrangements according to the invention allow the clamping means and / or the light influencing means to be moved from their operating position to the mounting position in which the interior of the recessed luminaire is at least partially or fully opened, thus facilitating and improving access. This makes it possible to make connection, repair and assembly or disassembly measures easier, more accessible and faster. In this case, the fastening means and / or the light influencing means are assured, since these parts remain connected to the recessed light by means of connecting means. In the context of the invention, the clamping means and / or the light influencing means can be arranged to be hinged, optionally pivotable or hinged. This allows access to the interior of the recessed luminaire without having to remove or store these parts separately.

The advantages obtainable by the invention can be achieved not only with a recessed luminaire but also with a built-in or freely suspended luminaire. Therefore, the invention is not limited to a recessed luminaire. Built-in luminaires and free-hanging luminaires are substantially identical with respect to the essential components of the luminaires, such as the clamping means and the light influencing means, but it is customary to provide these with a closed housing forming a clamping means or base part or and means for influencing light in the housing.

In the luminaire arrangement according to claim 10, the base part and / or the light influence means are in each case separate components, of which the base part is fastened by means of a respective coupling device releasable on the support parts and the light influence means are also releasable with the respective coupling device. advantage on the base portion. This also greatly simplifies both installation and access to the recessed luminaire. It is possible to mount the clamping device consisting of the carrier part and the mounting means into the mounting hole separately or together with the base part, which can be carried out very advantageously in terms of handling. It is also possible to use a base part pre-assembled from the carrier part. Furthermore, it is also possible to disassemble the base part from the built-in carrier part in order to connect, check or replace the arranged electrical functional parts, for example on the base part, in particular on its rear side. After fixing the base part, it is also possible to connect the reflector to the recessed luminaire in a convenient manner.

In some known recessed luminaires, lamp holders and lamella reflecting means are held on a tub which is provided on the base and is mounted on a head which is fixed by means of special fasteners either on the intermediate ceiling or above ceiling. The tub-shaped base part is provided with its side walls up to the built-in opening, the tub-shaped base part having a bottom part. a lateral edge formed in one piece by a laterally extending edge portion which overlaps or overlaps the edge of the built-in opening and creates a lower restriction for the base portion in the shape of the tub. The light influencing means is arranged above or below the peripheral portion in the tub-shaped base portion and is fixed to the base portion.

Based on the previously described known designs, known recessed luminaires are material-intensive and, moreover, are expensive to manufacture, and the material cost also results in a relatively large weight of the recessed luminaire. Furthermore, mounting or fastening in the lateral region of the base part is difficult, since access to the fastening elements from below is necessary, as can be seen from DE 37 39 076 A1.

The invention furthermore aims to simplify the recessed luminaire.

This object is achieved by a recessed luminaire according to the invention, the essence of which is characterized in that the edge part is connected to or formed in one piece with the luminous distribution device.

The advantages of this solution are that the base portion no longer has to be formed with downwardly facing side walls, but may have a substantially flat construction shape, possibly having an inwardly or outwardly recessed luminaire for receiving the means for supplying the lamp with operating voltage.

This substantially simplifies the construction of the base portion, thereby saving material and making production easier. Moreover, in this construction, since the side walls for the base part may partially or completely fall off, the side means for clamping the recessed luminaire from its interior are freely accessible, thereby substantially simplifying and facilitating the assembly and disassembly of the recessed luminaire.

The invention also relates to a built-in body according to claim 27, characterized in that the edge portion is connected to or formed in one piece with the luminous distribution device. The advantages described also apply to these solutions.

In the arrangement according to claim 28 or 29, a lateral adjustment and fastening is provided in the corresponding position of the clamping device on the base part. This arrangement is advantageous for several reasons. The recessed luminaire can be precisely adjusted in that the base part is laterally displaceable and mountable relative to the clamping devices. The recessed luminaire can also be adjusted laterally. A further advantage is that the recessed luminaire can be adapted to differently wide recessed openings and thus an equally recessed luminaire can be mounted in differently wide recessed openings. Thus, it is not necessary to form a correspondingly wide base part for each opening width. This arrangement according to the invention is particularly advantageous in connection with an edge portion for covering the edge of an opening, which can be arranged in the lower edge region of the basin-shaped base portion or preferably on the luminous distribution device. It is particularly advantageous here that the magnitude of the dimension of the possible displacement between the clamping devices and between the base part is adapted to the width of the edge part. In this way it is possible not only to adapt the recessed luminaire to different widths of the opening, but also to cover the edge of the opening.

The arrangements according to claims 33 and 34 contribute to simplification and, in particular, the arrangements according to claim 34 allow convenient handling access to the recessed fixture for the recessed luminaire through the open space.

The dependent claims disclose features which additionally contribute to simplification of the construction as well as assembly and disassembly, as well as to simplify and improve production.

In the following, the invention and other achievable advantages are explained in more detail on the basis of preferred embodiments and drawings.

The main parts of the recessed luminaire 1 are the base part 2, means for influencing the light, for example for deflecting, distributing, dimming and / or filtering the light as one or more light distributing devices, which here consists of a disc-shaped or perforated sheet diffuser. an aperture or reflector 4 with a lattice aperture, mounting means 5 for releasably holding the recessed light 7 in the recessed opening 6 of the built-in body 7 in which the recessed light 1 is accommodated, an edge portion 8 for closing recessed light 1 at the edge of the recessed opening 6 electric power supplying at least one bulb 11 and one or more, for example two sleeve-shaped means 10 in a corresponding number of one or more bulbs 11.

The base part 2 is a flat or plate-shaped component whose width a and length b are preferably smaller than the corresponding cross-sectional dimensions of a preferably rectangular built-in opening 6, the width a preferably also smaller than the distance c between by means of mounting means 5, which allows the base part 2 to be inserted from below into the recessed opening 6 of the recessed luminaire 1 formed here as a ceiling lamp. However, the width a or length b may also be larger than the dimensions of the recessed opening 6. 2 through the installation opening 6 in an inclined position. This is possible due to the flat construction of the base part 2.

In this arrangement, in which the recessed luminaire 1 has a longitudinally shaped construction for at least one tube 11, the base part 2 is formed of a longitudinal profile, in particular of metal, for example steel sheet, and is thus stabilized by the profile. There is provided a central profiled retraction 12 in which an operating means 9, for example an operating device or a switching device from the upper side, can be arranged recessed and thus with very little space requirement. In this configuration, the side walls of the profile are preferably in the form of angles with deflections from the base section 13 of the profiled retraction 12 with the opposing inner inclined sections 14 and the adjoining convergent inclined sections 15 therefrom, from which the preferably horizontal cross sections 16 extend. For stabilization, short angles or bends protrude up and down. In the region of the ends of the base part 2, the means 10 in the base section 13 are preferably inserted from above in the cut-outs 18 in the form of sleeves and are latched by means of resiliently bendable locking arms 19 ♦.

The holding means 5 are preferably four mutually identical, but with respect to the vertical central plane, in particular to the longitudinal central plane 20 of the recessed lamp 2, symmetrically symmetrically arranged holders 21 are arranged opposite one another and in the longitudinal recessed lamp 2 shown in end regions wide hillside. Referring to FIG. 1, the brackets 21 are fixed to the left and to the right and are always identical from the broad side, so that only one bracket 21 will be described below.

The right holder 21 is supported only on the mounting hole 6 comprising the mounting body 2 »here on the intermediate housing 7a, whereby the attachment of the intermediate housing 7a is not shown. It can be hung on the roof section above it. This holder is also suitable for a retaining built-in body 7 which is not formed by an intermediate cover 7a, for example in the case of a wall lamp 14.

The left bracket 21 is integrated into the suspension device 23 of the intermediate housing 7a, or is supported on the hinge element 23. The brackets 21 are preferably identical to each other despite these different supports, and are suitable for different supports, so that only one holder has to be described 21. This consists of a support leg 24 in the form of a support angle with a roughly horizontal support arm 24a which is mounted on the base part 2 and a roughly vertical support arm 24b, with a support portion 25 adjustable in height on the vertical support arm 24b, it also preferably has an angular shape with a vertical adjusting arm 25a of the support portion 25 and an approximately horizontal outwardly extending leg 25b of the support portion 25, and with a continuously adjustable height adjustable clamping element 26 in the form of a clamping element 26 on the vertical support arm 24b. and having a laterally projecting clamping arm 26a, and in particular an upwardly projecting clamping arm 26b, which is slidable vertically on the vertical support arm 24b by means of a slide 27 and can be fastened in any selected sliding position. The sliding guide 27 may be formed such that the clamping arm 26b embraces the vertical support arm 24b or is engaged by an extension (not shown) in a particularly downwardly extending groove 28. In this case, this arrangement is designed such that counterclockwise in FIG. By rotating the clamping element 26 in the form of the clamping part, the slide 27 automatically grips.

A clamping element 26 in the form of a clamping part made of resiliently flexible material, in particular spring steel, is suitable for this purpose. In the apex region of the support leg 24, an upwardly inwardly directed semi-circular bend 29 of the support leg 24a is preferably provided, into which the sliding guide 27 or groove 28, if provided, extends. Thus, it is possible to move the clamping element 26 to the mounting position shown in FIG. 1 in which it is displaced inwardly and projects upwardly relative to the position of the horizontal support arm 24b, so that when inserted into the mounting hole 6 vestavbu. Preferably, the support leg 24 is fastened laterally to its base part 2 by its vertical support arm 24b. To this end, a longitudinal bore 31 is formed in the base part 2 or in the vertical support arm 24b through which the respective fastening means, in particular the fastening bolt 32, extends. A comparable vertical adjustment may also be provided for the support part 25. For this purpose, a sliding guide 27 or a groove 28, through which a suitable fastening means passes, in this case a fastening screw 33, may also serve.

The suspension device 23 has a suspension portion 34 which is formed with two lateral hooks 34a in the form of a double hook or T-shaped with a head down, optionally as a longitudinally extending rail, its central upwardly projecting suspension rib 34b being height-adjustable on wire 35 or on the perforated strip by means of a suitable fastening means. The wire 35 or the apertured web is fastened to a lid portion disposed above the intermediate cover 7a, not shown.

The hooking hooks 34a may stand laterally or may be angled upward as shown in FIG. 1. Especially in the flat design, the hooking hooks 34a may be provided on the underside 7c of the intermediate cover 7a and abut, as is shown in FIG. This can be seen from FIG. 17. In such an arrangement, the respective suspension hook 34a is visible. However, it can also be partially or completely covered by the edge portion 8 of the recessed luminaire 10 which will be described. the arrangement shown in FIG. 1 is provided with a concealed hinge device 23. In such an arrangement, the built-in opening 6 comprising the intermediate cover 7a or the adjacent intermediate cover 7b in the apertured wall 38 has a recess 39 with a horizontal bearing surface 39a. by means of which the intermediate cover 7a or the corresponding part of the intermediate cover 7b bears on the suspension hook 34a, preferably by means of a groove 41, thereby providing a safety against side slip. The perforated wall 38a, which is disposed above the receiving surface 39a, is offset from the outside in order to enlarge the mounting opening 6, so that the hinge rib 34b has sufficient space in this enlargement.

The intermediate housing 7a may consist of a plurality of identical portions of the intermediate housings 7b, which in the sense of the facet housing are limited to a wire 35 comprising parallel or intersecting vertical planes, whereby in those regions where no built-in aperture 6 is provided they they may be hinged on the respective suspension hooks 34a, abutting them, which constitutes a visible arrangement, or may be abutted by the receiving surface 39a of the notch 39, which constitutes an overlapped suspension. The edge portion 8 of the recessed luminaire 1 is intended to provide a closure element with respect to the body 7, and can be arranged at least partially recessed in the recessed opening 6, forming a gap between its peripheral surface and the apertured wall 38 or abutting on the underside 36 The edge portion 8 is preferably provided along the entire circumference of the built-in aperture 6 in the form of a frame and can be formed in one piece or from frame sections 8a, 8b, 8c, 8d which are provided to the corners of the frame. The arrangement according to FIG. 1A, in which identical or comparable parts are provided with identical reference features, shows a structure with an edge part 8 which is arranged at least partially recessed into the installation opening 6.

The reflector 4 consists of a plurality of parts which are rigidly interlocked and thus held together, in particular a plurality of opposite side walls 45 and end walls 46 as well as transverse slats 47. In the longitudinal arrangement shown, two opposite side walls are provided walls 45, two opposing end walls 46 and more transverse strips 47. The sidewalls 45 are mirror-symmetrically curved S-shaped or concave in the upper region and divergent obliquely in the lower region, see Fig. 1. the walls 46 are formed vertically, slightly downwardly obliquely divergent or in the upper region vertically and downwardly obliquely or concave divergent. The sidewalls 45, the endwalls 46 and the crossbars 47 preferably consist of a metal sheet having a reflecting surface formed on their reflecting surfaces by a pre-fabricated metallic light reflecting surface, preferably aluminum sheet. The transverse slats 47 consist of folded sheet metal strips, wherein the folding tops are arranged at the bottom and the opposing side walls are slightly concave upwardly curved. To clamp the sidewalls 45 and the crossbars 47 on each other, corresponding V-shaped recesses 48 are embossed into the sidewalls 45, which grip the crossbars 47 with clamping bands 49 that are provided at the ends and which are embossed externally. The clamping bands 49 are provided at the top and bottom with upper edges 47a and lower apex edges 47b, thereby forming on the contour of the sidewalls 45 the shoulder surfaces 47c of the sidewalls 47d of the transverse lamellas 47 on which the sidewalls 45 are fixed. Referring particularly to FIG. 4, grooves 48a are provided in the upper corners of the recesses 48 for the tensioning belts 49 forming shoulder surfaces on which the side walls 47d are supported against bending into the recesses 48.

The engagement connection is also provided between the side walls 45 and between the end walls 46. Here, clamping bands 49 or clamping tongues provided at the end ends of the side walls 45 are provided by the extended sections, which extend beyond the end walls 46 and can be bent behind them. they also take up. In the illustrated arrangement, the end faces 46 are provided with larger dimensions than the end face limited by the two side faces 45, wherein the clamping tongues 51 extend through the end faces 46 in small cutouts and are bent behind them.

The side walls of the transverse lamellas 47 may be stabilized by means of stabilizing arms 47β curved together, which are provided over a large part of their upper edges 47a.

The edge portion 8 is preferably formed as one piece on the reflector 4, preferably at the lower edges of the side walls 45 and the front walls 46. In the illustrated arrangement, the edge portion 8 is formed by elongated curved strips at the lower edges of the side walls 45 and the front walls 46. in the corners of the reflector 4 of the provided joints 53 are connected to each other and stabilized by suitable fastening elements, for example by means of a joint gap 53 of bridging, appropriately shaped abutment portions 54 which are fastened to adjacent strips 55, for example by gluing.

The strips 55 are preferably stabilized by means of their bent arms 55a as shown in FIG. 1, or by their inwardly bent arms 55b, as shown in FIG. 5.

The edge portion 8 has a lower side 57 which is preferably horizontal, see FIG. 1, or rounded or obliquely upward, preferably with respect to the lower side of the reflector 4 at an angle w of about 30 °. In the present arrangement, the lower edges of the side walls 45 and the front walls 46 are disposed by dimension d deeper than the underside of the intermediate cover 7a and before the strips 55 are bent respectively upwards. The dimension d on all frame sections 8a, 8b, 8c, 8d preferably the same width e of the edge portion 8 can be about 10 to 100 mm, in particular about 30 to 60 mm, for example about 30 to 45 mm or 50 to 60 mm.

The edge portion 8 may also consist of a non-metallic material, for example wood.

The reflector 4 thus constitutes a prefabricated construction and assembly unit, which consists of side walls 45 and end walls 46 with shaped frame sections 8a, 8b, 8c, 8d and transverse lamellas 47.

For releasably fastening the reflector 4 directly or immediately on the base part 2 or on the bracket 21 or on the suspension device 23, another coupling device 58 is formed as a quick-release fastening, for example in the form of a snap-on engagement with snap-in elements 59. φ

releases with a certain amount of force, which are snapped into the latching recess in the fastening position. In the embodiment of FIG. 1, the latching elements 59 are arranged on resiliently pivotable or flexible latching arms 60, which are fastened to the upper edges of the side walls 45, for example by rivets passing through the holes 61. In the longitudinal shape of the recessed light X shown In this arrangement, the latching teeth of the latching elements 59 engage behind the outer inclined portions 15 of the base portion 2, the inner inclined portions 14 forming the tapered bevels and the outer inclined portions 15 here. release sections for latching elements 59.

In addition, it is advantageous to provide a centering 62 between the base part 2 and the reflector 4 to form a defined position between the base part 2 and the reflector 4. In the embodiment, the centering 62 is formed by inner oblique sections 14 and correspondingly angled edge strips 63 the shape of the recesses at the upper edges of the side walls 45 which abut one another in the mounted position. Based on this centering. in the shape of a wedge, the correct installation position can be found automatically when connecting the components.

The recessed luminaire X described above preferably consists of two structural units, namely a base part 2 with a built-in holder 21, a sleeve-like means 10 and a machine-like means 9, which form a pre-fabricated structural unit, and on the one hand, the light guiding means or the light distribution device or the reflector 4 with the edge portion 8, which form a pre-fabricated structural unit. To assemble, the base part 2 with the upwardly clamped clamping elements 26 is first inserted into the recess 6 against the supporting portions 25, which may optionally be adjusted, and then the clamping-part retaining elements 26 are pushed down and clamped against the built-in body. 7 to the right or opposite, respectively, the rail hinge parts 34, left-down. The height adjustments are readily possible by appropriately adjusting the support parts 25. Then, it is only necessary to insert the reflector 4 and connect it by means of a further fastening device 58 formed as a snap fastener to the base part 2 while simultaneously bringing the edge part 8 into its closure position. It is then possible to insert the bulb 11 into the sleeve-like means 10, if it has not already been done before. For disassembly, the disassembly can be carried out advantageously and quickly in the reverse order.

In the case where the end walls 46 are provided in the region of the sleeve-like means 10, preferably recesses adapted to the shape of the sleeves are provided in the end walls 46 and are open in the direction towards the upper edge.

The arrangement according to the invention is suitable not only for recessed luminaires with rectangular cross-section as described and as shown in FIG. 6, but also for all possible cross-sectional shapes, in particular also for square and circular cross-sectional shapes as shown in FIG. 7 and 8 as seen from below 22a. In a circular or rounded shape, the edge portion 8 can be formed in one piece in the circumferential direction. Particularly with a circular or square cross-sectional shape of the recessed luminaire 7 and corresponding to the width of the edge portion 8, the built-in opening 6 may have a substantially circular or square cross-sectional shape as can be seen in Fig. 8.

9, the three recessed luminaires according to the invention in the longitudinal direction of the light strip 65 are longitudinally connected one after the other in the longitudinal direction. The two recessed luminaires 1a, which form the ends of the light strip 65 and central or more central The recessed luminaires 1b may be formed in the sense of the foregoing constructions, but differ in terms of the formation of the edge portion 8 in the region of the transversely arranged vertical joints 66 on which they are opposed to one another.

In the area of the joints 66, all three recessed lamps 1a are missing. 1b, the cross-sectional frame section 8b and 8d respectively of the edge portion 8. Instead, they have longitudinally extending edge frame sections 8a, 8c in the joint 66 and thus a transversely arranged end surface in which they are mutually opposed and form the joint 66. Thus, the central recessed luminaire 1b has no cross-sectional subframe 8b, 8d at all, while the recessed recessed luminaires 1a have transversely arranged sub-frame sections 8b, 8d at their free ends. The length of the recessed lights 1a, 1b is adapted to the grid R of the cover of the built-in body 7 composed of so-called cover plates of the same dimensions that form the cassette cover. As a result, the respective edge dividing slots T of the cassette cover protrude transversely to the transversely extending edge frame sections 8b, 8d.

The width f and in particular the length vest of the installation opening 6 is easily and economically feasible in the ceiling if the width f and especially the length g correspond to the given dimensions of the grid R, r so that the installation opening 6 does not need to be modified in the ceiling in a particular way 6 to form a narrow ceiling slab P by omitting it.

In practice, the following special features have been created with respect to the width and length arrangement of the recessed luminaire. On the one hand, different grid sizes R, r have occurred in practice, which may be due to various causes, for example different manufacturers and / or different grid sizes R, r, in order to better distribute the ceiling surface. For example, the dimensions of the grids R of 1200 mm and 1250 mm, as shown in FIG.

and FIG. 12. Furthermore, at the same width f of the recessed opening 6, different installation widths are available for the recessed light X, depending on whether a suspension device 23 is used for clamping the recessed light X, as shown in FIG.

left, or bracket 21 as shown in FIG. 1 on the right. It can be clearly seen from Fig. 1 that the vertical support arm 24b of the support leg 24 in Fig. 1 occupies less space as seen in Fig. 1 to the right than the combination of the suspension device 23 with the Tas-shaped suspension portion 34 corresponding to the support leg 24. Due to the lateral adjustability in the region of the fastening screw 32, the supporting parts can be adapted to the corresponding manner and position of the holding. Furthermore, these adjustments allow adaptation of the recessed luminaire χ to recessed apertures of different width T. Since the edge portion 8 of the recessed luminaire χ allows overlapping in the area of its width e, one and the same recessed luminaire χ is possible with base 2, corresponding luminance device 3 and mounting means. 5 can be used for different widths and long installation openings 6 in a certain width region, if the length difference DL and the width difference DB are not greater than the width e of the edge portion 8 and are in the region of the maximum and minimum width of the edge portion 8. 1, where the installation opening 6 of maximum width is shown on the left and the installation opening 6 of minimum width is shown on the right. In the latter case, the rim portion 8 may also overlap the abutment portions 25 provided under the intermediate cover 7a. In this case, the light distribution device 3, the base part 2 and the support legs 24 are each adapted to the smallest width corresponding to the width region.

This can also be recognized in terms of the length of the recessed opening 6 based on FIGS. 10 and 12. FIG. 10 shows a smaller opening 6 of the recessed opening 6 to which the recessed luminaire 2 is adapted with its base part 2 and the luminous distribution device 3. This recessed luminaire 2 is also suitable for the built-in / built-in aperture 6 of greater length podle according to Fig. 12, since the edge portions 18 overlap the length difference DL of the hole length.

10 and 12 allow different bulbs 11 to be used, the bulb 11 of FIG. 12 being able to extend over the front walls 46 of the reflector 4 in the region of the length difference DL. For mounting such a bulb 11, it can be provided for the sockets of the base part 67, which sockets are mounted on the base part 2 and extend beyond the front ends thereof, as shown in Figs. 10 and 12. 10, the two sleeve-shaped means 10 shown are spaced from the ends of the base part 2.

In the arrangement of FIG. 10, two U-shaped bent contact tubes are used. Thus, the recessed luminaire 1 is variable not only in terms of its adaptation to different widths f and length g of the recessed opening 6, but also in terms of the incandescent bulbs 11. Also in these recessed luminaires the corresponding luminous distribution device 3 can have reflectors 4 with or without grille and / or transparent or damping cover or the like.

In the case of using a shorter bulb 11, it is advantageous to close the two recess-shaped edge strips 63 in the region of the reflector 4 with the closure portion shown in FIGS. 1, 11 and 16, which can be connected to the respective front wall 46 of the reflector 4. via quick release or plug-in connection. In the arrangement of FIG. 14, the closure portion 68 is formed by a plate 69 that is larger than or can be adapted to the shape of the edge strip 63 in the shape of a recess and has at least two angular clamping arms 71 that are attached to its outer side In the region of the edge strip 63 in the form of a recess at its edge and with their angular arms they engage the respective end wall 46. Preferably, these are spring arms which clamp the plate 69 against the end wall 46 and thus reduce knocking noise. In this arrangement, one clamping arm 71 is provided in the lower region of the recess and two clamping arms 71 in the upper region.

The arrangement of the reflector 4 and the edge portion 8 of Figure 15, in which identical or comparable parts are provided with identical reference features, differs from the previously described arrangements in two respects. On the one hand, the edge portion 8 is not formed as a single part on the reflector 4, but is a separate component which can be connected non-releasably or releasably to the lower outer edge of the reflector 4, for example by gluing. In this case, it is advantageous to provide both a vertical bearing surface 73 and a horizontal bearing surface 74 for positioning the edge portion 8 on the reflector 4.

A further difference is that clamping means 75 are provided on the peripheral part for the luminous distribution device 3 or the reflector 4 of the arranged part, such as a lower disk 76 with longitudinal grooves with optical features or a protective disk.

Otherwise, the edge portion 8 or the light distribution device 3 may correspond to the previously described arrangements. The clamping means 75 is here formed by a disk 76 with longitudinal grooves that are open inwardly and are limited by the hook arms 77.

In the recessed luminaire arrangement of FIG. 16, which is connected to the arrangement of FIG. 1, the mounting means 5 are each associated with a level adjuster 81, which is always integrated into the holder 21. In this arrangement, the support part 25 or the arm 25b of the abutment portion 25 surrounding the edge of the bore 6 or of the overhead portion 34 is provided on a slide 82 which is vertically adjustable by means of an adjusting screw 84 in a guide 83 disposed therebetween and the vertical abutment arm 24b. Settings. The adjusting screw 84 is mounted rotatably and axially between the ram 28 and the vertical support arm 24b, i.e. non-movable in the vertical direction, and is accessible from below for a suitable tool such as a screwdriver. In the configuration, the adjusting screw 84 is held axially non-movably on the vertical support arm 24b and a threaded engagement 85 is formed between the ram 82 and the thread of the adjusting screw 34, which can be formed by molding in that wall of the ram 82 that abuts the adjusting screw 84. a further support arm 24d is provided on the outside of the ram 82, which is formed in the same way as the support arm 24b in the preceding examples but is not connected to the base part 2 but is freely terminated at the top by a curved seat 86 for movement The adjusting screw 84 is accessible after removal of the luminous distribution device 3 or reflector 4, from below for height or level adjustment or alignment.

Instead of the previously described self-retaining clamping elements 26 in the configuration shown in FIG. 17, the clamping portions 91 with a laterally extending retaining arm 91a for the overhang of the intermediate cover 7a or parts of the suspension device 23 are associated with the holders 21. the overhang of the rail suspension portion 34, whereby also there is a fastening between the arm 25b of the support portion 25 and the retaining arm 91a, which portions can also act as a clamping effect between them. The bracket 21 is vertically displaceable in the sliding guide 27 on the vertical support arm 24b and is mountable in the corresponding sliding position.

For this purpose, the clamping portion 91 may have an upward or downwardly fastening arm 91b which, as an angular-shaped support portion 25, is releasably fastened by a fastening screw 33 to a vertical support arm 24b that extends through the mounting arm 91b in the opening and through the vertical support. arm 24b in groove 28.

In all the previously described arrangements, the brackets 21, based on the flat or plate arrangement of the base portions 2, are, after removal of the luminance distributing device 3, preferably accessible for manipulation from the recessed lumina space 1 between the brackets 21, enabling mounting or dismantling. preferably from a handling point of view.

Within the scope of the invention, it is also possible in all the described arrangements not to fix the luminance distributor on the base part 2, but to attach it to the holders 21, to the lower ends of the vertical support legs 24b or to the legs 25b of the support part 25. for example, a snap-in device in order to achieve a fast and easy to install and / or disassembly of the light distribution device 3.

Instead of directly between the base portion 2 and between the luminous distribution device 3 of the acting latching device, the same or other connecting means 58 formed as a quick-lock can be provided between the luminous distribution device 3 and between the holders 21 or mounting means 5 for clamping. In the arrangement of FIG. 18, clamping elements are provided in the free end regions of the vertical support arms 24b for the luminance distributor 3, in particular for its edge portion 8. The clamping element may be held on a corresponding arm 25b of the support portion 25. It may also be arranged movably between The clamping position and between the released position in the guide 90 and in its clamping position can preferably be influenced by a spring force. Referring to FIG. 18, the hooked or jaw-provided fastening portions 92 are slidably mounted on a corresponding arm 25b of the support portion 25 between an inner clamping position in which the clamping jaw 92 extends beyond and extends below the peripheral portion 8 and extends outwardly therethrough. the clamping jaw 92 releases the edge portion 8 and can be inserted by the luminous distribution device 3 with its opposite edge portions 8 from below between the clamping jaws 92a, being fixed in the clamping position by a clamping device or secured by a spring force.

The recessed luminaire shown in Figure 18, in which identical or comparable components are provided with the same reference features, differs from the previously described arrangements in several respects.

On the one hand, the base part 2 has a different constructional shape and is not directly connected to the support legs 24 or support angles, but through two or more longitudinally spaced support portions 101 with which the support legs 24 or support angles are releasably connected, preferably Each carrier part 101 forms, with two bridge-shaped support legs 24, a bracing device 103, on which the base part 2 is attached releasably or hingedly by means of a connecting device 104. The releasable coupling device 104 is preferably formed by a quick-release or snap-on device 105, and when folded away from the base portion 2, this is coupled via a preferably releasable hinge-like coupling 106 to a clamping device 103, in this case a longitudinal side of the base part 2, wherein the latching device 105 is arranged on the opposite longitudinal side. This makes it possible to tilt the base part upwards when the light distribution device 3 is removed, thereby bringing the electrical connection elements and means 9 in the form of operational power supply devices arranged on the base part 2 into a convenient operating position, which makes it possible to connect electrical connection cables to the connecting elements advantageously and quickly from a handling point of view. Subsequently, the base part 2 can be swiveled back into its mounting position and, in terms of handling, can be connected advantageously and quickly.

A further difference in the arrangement is that the quick closure or the other coupling device 58 can be conveniently and quickly mounted on the luminance distributor 3 in terms of handling. In this arrangement, spring-like extension portions 107 are provided on both sides of the reflector 4, with snap-in claws 108, which always spring elastically behind the corresponding snap-in projection on the base part 2, in particular in the region of the bent or angled arms 109 of the base part 2.

Further, the other arrangements have retaining elements 26 in the form of clamping portions, which will be described hereinafter.

In addition, an additional reflector portion 111 is provided for overlapping the apex region of the reflector 4, which is operatively and quickly connectable to the underside of the base part 2 by means of a quick-action or snap-fit connection or a latching device 112. opposing and inwardly clamping tongues 113 which are bent obliquely downward and extend beyond the reflector portion 111 with the edge portions 111a. Connection of reflector part

111 can be done by manually compressing, allowing the edge portions 111a to be inserted between the clamping tongues 113 where, due to the inherent resilience of the reflector portion 111, it is elastically expandable, or the reflector portion 111 can be inserted longitudinally between the clamping tongues 113.

Hereinafter, the individual components of the exemplary embodiments will be described.

As can be seen from FIG. 19, the base portion 2 is preferably formed with a directly formed base rib 114 and a U-shaped cross-section of the base legs 109, wherein semi-circular bent snap edges 115 formed as longitudinal ends are formed in the end regions of the base legs 109. serrations, under which the snap-in claws 108 can be snapped into place.

A special recess 116 is provided in the end regions of the base arm 109, which is part of the joint means 106 in the form of a hinge. The recess 116 is provided only over a portion of the length of the base arm 109, starting at a distance h from the base rib 114, extending downwardly through the latching edge 115 formed as a longitudinal notch and terminating at a small distance from the free edge of the base arm 109 provided approximately parallel to the base rib 114. In the upper region, the insertion recess 116 has a insertion extension 117 on one side or on both sides, the function of which will still be described in the other.

At the front ends of the base part 2, curved end walls 118 are provided which partially limit the hollow space of the base part 2 on the front side.

The base part 2 is made as a stamped, flexible piece in one piece of platinum made of sheet steel, as shown in plan view in FIG.

The support portion 101 comprises a first U-shaped connecting portion 101a for connection to the support legs 24 and a second connecting portion 101b for connection to the base portion 2. The support portion 101 is formed with a rib portion 119 and arms 121 that are bent upwardly from their longitudinal edges and thus form a U-shaped cross-section, which is directed transversely to the base part 2. In the end regions of the legs 121, there is provided one latching mouth 102 each for releasably connecting the respective support leg 24. 102 is formed by an insertion recess 122 in one arm 121 and a latch tab 123 in the other arm 121. The latch tab 123 is cut from the respective arm 121 by cutting 124 and is bent upward as shown in FIG. to the area of the rib portion 119. Free end The latch member 123 may be tapered to the latch pin 125 as shown in FIG. 22. The two latch members 102 are laterally inverted, so that one arm recess 122 and one arm latch 123 are disposed in each arm 121.

The second connecting portion 101b is formed by two connecting arms 126, 127 which are provided facing away from the rib portion 119 to the arms 121, downwardly here and are preferably bent in one piece, the spacing between the connecting arms 126, 127 having such a dimension In this arrangement, a rectangular stepped bend 128 is provided in the foot region of the two link arms 126, 127, the arrangement being such that the base part 2 is flush with a slight movement clearance between the first stepped sections 129 .

There are two support portions 101 with corresponding mounting means 5, the spacing of which is adapted to the central distance j of the insertion recesses 116 in the base part 2. At the ends of the connecting arms 126, sliding portions 131 are arranged on one or both sides. 126 and the engagement portions 131 are adapted to the width dimensions of the engagement recess 116 so that it is possible to engage the engagement portions 131 into the engagement extensions 117 and engage therein relative to the end region of the engagement recess 116. A cutout for electrical components or cables is provided in the central lower region of the mounting portion 131.

An opening 132. is provided in the free end region of the connecting arm 127. In addition, an insertion recess 122. may be provided at the end edge of the connecting arm 127. As can be seen from FIG. 25, each support portion 101 is also formed as an embossed bent portion. and bent as one piece of platinum sheet.

In the region of the horizontal support arm 24a, there is a male protruding pin 137 on one side and a male recess 138 on the other side, which forms parts of the latching device 102. The male pin 137 can be inserted into the male recess 122 with slight movement. In this position, the insertion recess 138 is associated with the engagement tongue 123 or the engagement pin 125 so that it engages the insertion recess 138. Thus, the horizontal support arm 24a is preferably, stably and securely releasably fastened to the engaging recess 138. Advantageously, the insertion pin 137 and the insertion recess 138 in the region with respect to the vertical shaft of the support leg 24 are tapered to a reduced width k, which fits with a slight movement clearance between the legs 121 of the support portion 101. direction offset stepped surfaces 139, which can abut against the support portion 101 on the front side, thereby facilitating both the retracting operation and the stability. At the foot end of the support leg 24, the arm 25b of the support portion 25 is bent horizontally, preferably in the notch region in the form of two mutually opposed grooves 141 which allow up to the grooves 141 provided with the lateral edge portions 142 slightly bent to form roughly convex contact surface for built-in body f.

The sliding guide 27 has a longitudinal slot 135 in the support leg 124, which extends from the heel region of the vertical support arm 24b up to the arc or semi-circular bend 29, and if a vertical support arm 24d is provided between the semi-circular bend 29 and the horizontal support arm 24 up to the support arm 24d. The vertical support arm 24d is provided if the semicircular bend 29 is to extend over the support portion 101. At that end of the longitudinal slot 135 that faces the foot of the support leg 24, a centrally narrow notch 143a is provided which results in an extension 143 of the notch 143a. . This is arranged in the bent portion and in the assembled state in the support portion 101 of the protruding leg portion 24 or in the horizontal portion of the stepped bend 35.

In the configuration of the clamping element 26 and its clamping connection KV according to FIGS. 18 and 19 to 31, the clamping element 26 is formed by a lower clamping arm 26a and an upper clamping arm 26b. 45 °, the apex preferably being rounded. In the area of the curvature or its end regions, two guide grooves are provided one above the other in the clamping arms

144. 145. of which the heat is formed by the side recesses and the lower outwardly facing tongues 146 forming angular undercuts 147. The tongues 146 are preferably rounded and bent downwards, thereby avoiding the formation of a sharp bearing edge and instead forming rounded a narrow notch 149 is formed in the free end region of the upper clamping arm 26b, in which preferably a rounded notch extension 151 results. In the region of the lower clamping arm 26a, a longitudinal slot 152 is provided, from which an inwardly directed notch 153 extends from the inwardly directed end, resulting in a preferably rounded notch extension 154. The arrangement is designed such that the notch extensions 151, 154 are arranged approximately vertically one above the other. To stabilize the clamping arm 26a, it is advantageous to provide it with upwardly curved reinforcing arms 155.

In the free end region, the clamping arm 26a is bent downward in a roughly Z-shaped manner, and its receiving portion 156 may be tapered and may have a laterally slightly upwardly folded edge strip 156a. The free end of the upper clamping arm 26b is preferably rounded or pointed in the shape of a wedge. The clamping element 26 is preferably formed as a one-piece, bent-out bent part, for example of steel or spring steel, as shown in FIG.

In this embodiment, the sliding guide 27 is formed by a longitudinal slot 135 and the edge strips 156a of the support arm 24b. For this purpose, the distance m between the guide grooves is

144, 145 provided with a slight movement clearance less than the width n of the slot 135 so that the transverse edges of the guide grooves 144, 145 extend with the movement clearance below the edge strips 156a. Due to the relatively long length ratio of the functional distance o between the transverse edges 157 and between the respective bearing surfaces 148 and the length δ of the clamping arm 26a, a clamping in the guide 27 is automatically formed when the clamping element 26 is moved upwards, as the clamping arm 26a moves upwards. The clamping effect is further enhanced by the transverse edges 157. In contrast, the clamping element 26 can be displaced relatively easily when the engagement point for displacement thereof is close to the guide grooves 144,

145, as shown by the distance g1. If the clamping element 26 is moved against the built-in body 7, the clamping connection 27 automatically establishes a clamping connection KV on the ground on the clamping arm 26a of the resulting clamping or bending stress, which is represented by the upward arrow 158.

The displacement can be carried out manually or by means of a displacement device. In the first case, this can be done in terms of handling, preferably in the area of the free space between the base part 2 and between the built-in body 7. For the second case, notch extensions 151, 154 are preferably provided, which will be described later.

The snap fastener or the latching device 105 is formed by a latching tooth 161 and a latching edge beyond which it latches, the edge being resiliently flexible and thus the connection is releasable. In this arrangement, the latching tooth 161 is part of a latching spring 162 that resiliently engages latching edge 163. The latching spring 162 is fixed to the clamping device 103, preferably by means of an extension of the link arm 127, and is preferably mounted thereon as a separate component, e.g. bolted or riveted by means of screws or rivets that pass through holes 132 and 132a. The latch tooth 161 is bent into a single piece, and the latch tooth 161 has a chamfer 164 on the underside that ensures the latch tooth 161 bends and locks automatically at the latch edge 163 when the latch mechanism 105 closes. it is preferably made of flat spring steel. To prevent twisting in the screw or rivet joint, the latch spring 162 has at its foot end a small angle 165 that extends into the recess of the component that carries it, i.e. in the present case, the recess 165a on the connecting arm 127. Preferably, the shaft is 160 of the snap spring 162 is formed in its U-shaped foot region on the head, thereby increasing the length and improving the resilience. The free end region of the latch spring 162 is in the latch position to the side of the reflector 4, so that it can serve as a manipulative viewfinder 166 for bending and opening the latch 105. Either one central or two recessed luminaires 2 are provided a snap-action device 105 or snap fasteners.

The snap fastener or latch assembly 105 with the described structure and function may also be provided for a further coupling device 58. In this arrangement, the further coupling device 58 is also formed by a spring-shaped extension portion 107 and integrally formed therewith with a snap-fit tooth 108 which The spring-shaped extension part 107 is preferably letter-shaped, its upper bulge forming a latching tooth 103. In its heel region 172, the spring-shaped extension part 107 is fixed to the outer surface of the clamping device 103 or preferably to the reflector. the side of the reflector, for example by screwing or riveting as shown. Also, in order to prevent rotation in the fastening here, the free end of the spring shoe 103 is bent, for example in the form of a plug-in pin and extends into the plug-in opening in the reflector 4.

The latching tooth 108 is in the form of an inclined leading surface 174 which provides for automatic bending and snapping over the latching edge 115 formed as a longitudinal notch and forming a latching edge 163. Preferably, the latching tooth 108 is also formed on its opposite side with respect to the leading surface 174 In this case, the biasing force 162 of the latch spring 162 is such that the release due to the net weight of the reflector 4 is prevented and occurs only when the specified manual pulling force is applied. . In the context of the invention, it is possible to provide a pair of mirror-symmetrically arranged other coupling devices 58 formed in the central region of the recessed luminaire 1 or to provide two such pairs in the end regions of the recessed luminaire 1.

The arrangement of FIG. 34 in which identical or comparable parts are provided with the same reference features differs from the arrangement of FIG. 18 in two respects. On the one hand, the support portions 25 or the arms 25b of the support portions 25 extend below the respective suspension ribs 34b of the suspension device 23, the suspension ribs 34b extending with their arms on the outside under the intermediate cover 7a, preferably into the recess 176 on the bottom.

In both the embodiment of FIG. 18 and the embodiment of FIG. 34, the configuration is configured such that transverse transverse dimensions of the bore 6 or suspension ribs transversely across the vertical support legs 24b or respective sections of the support legs of the stepped bend 134 34b, thereby ensuring lateral positioning of the recessed luminaire JL.

Another difference with respect to the arrangement of FIG. 18 is that a distance is provided between the front ends of the support portion 101 and between the semicircular bends 29, thereby increasing the travel of the sliding guide and reducing the height of the support legs.

In the present embodiment, it is also advantageous to arrange the clamping device 103 so that the spacing of the support legs 24 is adjustable so that the recessed luminaire 1 can be adapted to different widths of the mounting openings 6. For this purpose different support legs 24 with different lengths can be provided. horizontal support arms 24a or carrier lengths of different lengths, the length differences of which are adapted to existing stepped steps of the width of the bore 6. It is also possible within the invention to provide multiple parts of the latching device 102 on the carrier part 101 or on the horizontal support arms 24a. the spacing between a plurality of portions 40 of the mounting device 102 is adjusted according to the stepped jump of the differently wide installation openings 6.

In the arrangement according to FIG. 35, in which only the side half of the recessed lamp 10 is shown, a mechanical adjusting connection means 181 is associated with the clamping element 26, in particular to move it to the clamping position. The adjusting means 181 is formed by a pulling device with a pulling cable 182 which engages the clamping element in the region of the sliding guide 27 and is accessible from the free interior 183 in front of the built-in body 7, e.g. For such a cable drive, notch extensions 143, 151, 154 are provided in the support legs 24 and in the clamp-shaped retaining elements 26. As can be clearly seen from FIG. 35, a pulling cable 182 is provided on the outside of the respective support leg 24, here on the side of its vertical support arm 24b. Preferably, the pulling cable 182 does not engage on the lower clamping arm 26a, but on the upper clamping arm 26b, passing through the lower clamping arm 26a in the passage opening with movement clearance, preferably with a protective sleeve 184 which is mounted on the pulling cable 182 the pull cable 182 from damage at the opening edge. At the upper free end of the tow cable 182, preferably an annular head 185 is mounted which extends over the upper clamping arm 26b, here the notch 151. Manual engagement on the tow rope 182 of the enhancing head 185 may also be provided at the lower end of the tow rope 182. When the corresponding clamping element 26 is manually moved, the tow rope 182 is self-tightening. The pulling cable pulls 182 on the upper clamping arm 26b are advantageous because the pulling force exerted thereto lifts the transverse edges 157 away from the vertical support arms 24b and thus makes it easier to slide. Such a adjusting connection means 181 is associated with each support leg 24. By manual pulling on the pulling cable 182 with the luminance distributor 3 not yet mounted, it is possible to pull the clamping element 26 in its clamping part from its pre-assembled preparatory position against the respective built-in body 7 or suspension. the rib 34b, which self-grips with the support leg 24.

For the luminous distribution device 3 or for the reflector 4 there is provided a disconnecting device 191 having at least one cable or the like, which is fixed at one end in the region of the installation opening 6, for example to a part of the suspension device 23 or to the support legs 24, The light distribution device 3 is fixed to the cable or can be fastened with a hinged plug connection 192 so that it can be removed in the disassembled state. The dimension of the disconnecting device 191 is determined with a view to handling convenient operation. Advantageously, the dimension s is chosen so that the disconnected light distribution device 3 can be easily swiveled laterally, further improving access to the recessed luminaire. Furthermore, it is advantageous to provide a cable disconnecting device 191, here in the form of a cable, laterally offset in the region of the recessed light fixture χ, which means that the upper end of the cable is fastened laterally offset to the recessed lighting portions 1, particularly the support legs 24. and the lower end of the cable is also mounted laterally on the luminous distribution device 3. In such an arrangement, a hinged or deflecting device is integrated in the disconnecting device 191 at the same time because, due to the lateral arrangement, the luminance distributing device 3, which is disconnected, is folded downwards.

In the case of longitudinal luminaires, as in the case of fluorescent lamps, it is advantageous to provide two longitudinally spaced from each other or in the end regions of the recessed luminaire.

Furthermore, it is advantageous to provide a hinged or disconnecting device 191 laterally offset on the side on which the laterally offset hinge joint 106 is also provided.

In this arrangement, the disconnecting device 191 is integrated into the adjusting fastener 181, which means that the cable 182 of the adjusting fastening 181 serves to disconnect the luminance distributing device 3, so that no additional disconnecting element is required. In this case, it is advantageous to provide a further engagement element 186, for example in the form of a spherical head 185, spaced from the engagement element 186 on the cable.

In the arrangement of the cut-off device 191, it is important that the cut-off element is fixed to the light guide in such a position that the cut-off element or cable 182 is not visible in the assembled position of the recessed luminaire. Therefore, the disconnecting device 191 and / or adjusting means 181 are very suitable for the present embodiment, in which the luminous distribution device 3 has a built-in opening 6 overlapping the edge portion 8 over the entire circumference or in particular with longitudinal recessed luminaires χ only on both longitudinal sides.

As shown in Figs. 35, 36 and 37, the hinged engagement connection 192 is disposed on the respective rear side of the reflector 4. It is formed by an engagement eye 193 and a projecting engagement eye 194, preferably in that region of the body portion. 107 in the shape of a spring, which is close to the reflector 4. The insertion eyelet 193 or aperture has a larger dimension than the head 185 on the cord 182, the insertion eyelet 194 or the insertion slot being slightly wider than the cross-section of the cord 182 so 38, in the disconnected position of FIG. 38, the cable 182 is pulled to the closed end of the insertion groove on the basis of the weight of the light distribution device 3, thus preventing the coupling from automatically unhooking. In this arrangement, the engagement groove is provided from the engagement eye 193 in the direction of the free end of the snap spring.

Next, the method steps for mounting the recessed luminaire 1 on the basis of Figs. 36 to 39 are described.

For the intermediate assembly of the recessed luminaire 1, the base part 2 is pre-assembled with the respective electric means 9 and preferably the rear side thereof, and the support part 1 is inserted into the joint-like coupling means 106 and the coupling device and the latching device are closed. are supplied with the respective support legs and the luminous distribution device 3 as separate, not pre-assembled components at the installation site, the support legs 24 with the corresponding clamping element 26 forming a single unit in the relaxed position and preferably with the adjusting means 181 . Thus, the recessed luminaire 7 has only three types of construction units 44, B1, B2 and B3 to be mounted on the recessed opening 6, i.e. the structural unit B1 formed by the base part 2 and the supporting parts 101, the structural unit B2 of four support legs 24 and a unit B3 formed by the luminous distribution device 3.

The mounting of the support legs 24 on the support part 101 can be advantageously and quickly carried out on the construction site or in the installation opening 6 by means of a retractable connection, as shown in FIG. 36.

According to FIG. 37, the further assembled unit B4 may advantageously be pushed into the installation opening 6 by first inserting the clamp-like retaining elements 26 into the non-disturbing mounting position in which they are moved inwards if they were not already there. . Then, it is only necessary to withdraw and clamp the retaining elements 26 in the form of the clamping part against the built-in body 7, in this case against the intermediate housing 7a. the retaining elements 26 in the form of the clamping part self-clamping on the support legs 24.

A further assembly step consists in folding down the base part 2 according to FIG. 38, whereby the spaced-apart electrical connection elements at their rear side are brought into a position which is advantageously accessible from a mounting point of view, so that the electrical connection can be made. Thereafter, the base part 2 swings upward to its end position, engaging automatically. Then the insertion of the bulb 11, here in the form of a tube, can be carried out and the insertion of the connection of the luminous distribution device 3 into the recessed luminaire L is completed.

It is advantageous to connect the luminous splitter 3 before insertion with the cable 182 of the disconnecting device 191 or the adjusting means 181, as shown in FIG. 38, and then insert it in a recessed luminaire

35, or may be placed on the edge portion 8. If the luminous splitter 3 is so mounted, the later opening is substantially simplified, for example to replace the bulb 11, since the luminance distributing device 3 can be easily disconnected and thus it is possible to perform these operations more advantageously, simpler and better in terms of handling. In the opposing disconnecting device 191, the cable 182 is not connected to the reflector 4. The free end of the cable 182 can be provided on the reflector 4, here on the edge portion 8.

In this exemplary embodiment, each of the support legs 24 or the four support legs 24 associated with the adjusting connection means 181 can also be provided separately by means of one or, in the case of a longitudinal recessed lamp 2, preferably two disconnecting devices 191 which are preferably arranged in the region of the support legs 24. .
