The Applicant has been developing and manufacturing recessed luminaires for wall-mounted installation, for installation in a ceiling, a side wall or a bottom wall of a building or a building part or an outer surface for decades.

In the following, in particular, the case of a ceiling-side installation of the lamp will be described, it being noted at this point that the invention explained below with reference to a recessed ceiling luminaire also applies to other recessed wall luminaires application and they should be covered by the protection.

Conventional recessed ceiling lights are available in different variants, which vary depending on the desired function. Also, the nature of the building wall, z. As the thickness of a false ceiling, the type of plaster, the height of the available ceiling space, the desired light distribution and not least the desired design of the light, play a role in the selection of the desired light. Known lights are each made for the individual purpose and consist of numerous individual parts. This is z. B. associated with a complex storage, since the often requested in small quantities luminaires must be made individually.

The object of the invention is, starting from the known state of the art, to develop a module construction system for recessed luminaires, which involves the use of a large number of identical parts and can react flexibly to the situation-dependent needs of the user.

The invention solves this task initially with the features of claim 1. Accordingly, a module construction system for a recessed luminaire is proposed, comprising at least three, provided in different variants components that can be optionally assembled using different variants to different recessed lights, wherein a first Component is provided by an annular mounting member comprising fixing means for wall-side fixing, wherein a second component is provided by an annular receiving element, which comprises connecting means for releasably securing to the mounting element and receiving means for directly or indirectly receiving a light head, and wherein a third Component of a reflector element, in particular of a sub-reflector, is provided, which is releasably secured to the receiving element.

The principle of the invention consists essentially in providing a recessed luminaire comprising three essential components. The first component is a mounting element, the second component is a receiving element and the third component is a reflector element.

Thus, an annular mounting element with an annular receiving element is connectable, and a rectangular mounting element with a rectangular receiving element connectable.

In the following, only a plurality of the variants of the components will initially be described, which rely on annular mounting elements and annular receiving elements.

The mounting element has fixing means for wall-side fixing. The fixing means allow an immediate attachment of the mounting element to the wall.

In this case, for example spreading springs can be provided as fixing means, which can engage behind a wall-side mounting surface in the installed state. For example, two expansion springs may be provided which extend approximately tangentially away from the annular mounting element.

Finally, as a further fixing means of the third kind, for example, holding blocks may be provided, the z. B. are pivotally mounted and axially movable relative to the mounting element.

Generally speaking, different variants of the mounting element with the same size, ie in particular with the same inner diameter, may have different fastening means, which allow a definition of the mounting element to different ceiling types or ceiling wall thicknesses.

The modular construction system according to the invention also has a receiving element, which also exists in different variants. The receiving element is also substantially annular. A first variant of a receiving element has two axially extending struts, on which retaining clips are fastened for fastening a lighthead.

These serve to achieve a different positioning of a light head relative to the mounting element. A further variant of an embodiment of a receiving element may have differently long trained headband with the same strut length to achieve the same purpose.

The receiving element is releasably attachable to the mounting element. Serve this purpose connecting means which are the same design in all variants of the receiving element. In an advantageous embodiment of the invention, the connecting means are formed by axially aligned spring tabs on the receiving element, which are radially displaceable. The spring tabs may have a holding surface, which rests in the assembled state of the receiving element on the mounting element, on an upper side of a radially inwardly projecting annular collar of the mounting element.

The designated in its entirety by the reference numeral 10 module construction system for a luminaire 11 is explained below with reference to the figures and with reference to different embodiments of the individual components of the modular building system 10. The following description of the figures should be preceded that for reasons of clarity the same or comparable parts or elements of the module building system 10, even as far as different embodiments or variants are concerned, are designated by the same reference numerals, partially with the addition of small letters.

The module construction system 10 according to the invention comprises a plurality of components, each provided in different variants. A first, essential component is an annular mounting element 12, which is based on the representation of Fig. 1 is presented as a circular trained mounting element 12a. An alternative variant of this component shows Fig. 2 in the form of a circular-shaped built-in element 12b and Fig. 3 with a further variant in the form of a circular-shaped built-in element 12c.

Other variants of built-in elements, which are square-ring-shaped show Fig. 56 in the form of the mounting element 20a and Fig. 57 in the form of the square mounting element 20b.

Finally shows Fig. 58a a built-in element 20c, which comprises two square built-in elements 20a arranged directly next to one another, as well as Fig. 58b in the form of the rectangular mounting element 20d, which two square juxtaposed square mounting elements 20b according to Fig. 57 includes.

The module construction system 10 according to the invention further comprises a second component in the form of a receiving element, which also consists of several variants. A first embodiment of a circular-shaped receiving element shows Fig. 8 , Wherein belonging to the receiving element headband are not shown there. The headband are for example in the Fig. 14 recognizable and serve to connect the receiving element 13 with a light head 15th

Depending on the choice of the desired light head different headband, and insofar different receiving element 13, are used.

A further embodiment of an annular, there square-shaped receiving element shows Fig. 40 ,

While an annular receiving element basically cooperates with an annular mounting element, a rectangular or square annular receiving element is basically connected to a rectangular or square mounting element.

The modular construction system for recessed luminaires according to the invention furthermore comprises different variants of a reflector element 14. A first variant of a reflector element is shown Fig. 28 in the form of the reflector element 14a. Another variant of such a reflector element shows Fig. 33 in the form of the reflector element 14b.

Variants 14a and 14b show reflector elements 14a, 14b with a circular light exit opening.

Another variant of a reflector element shows Fig. 45 Here, the light exit opening is square in adaptation to the geometric shape of the receiving element and the mounting element. This reflector element bears the reference numeral 18.

A basic principle of the module construction system according to the invention for recessed luminaires is that the different variants of the components of this system 10 can be combined with one another almost as desired. This is possible due to the choice of defined mechanical and photometric interfaces. The individual components are to achieve the desired properties of the recessed luminaire, both as the attachment to the wall, in terms of the design properties of the lamp but also as regards lighting properties of the luminaire optimized. Due to the modular design of the recessed luminaire 11 according to the invention, a particularly simple on-site assembly can take place:

First, the mounting element is fixed to the mounting wall. The installation element provides an insertion opening for the receiving element and the light head.

The receiving element can be used with the attached light head inserted into the mounting element and easily fixed to this. For this purpose, fixing means may be provided which will be described in detail later. Subsequently, the reflector element can be easily attached to the receiving element.

These three assembly steps can take place at a distance from each other and in particular be adapted to the processing steps on the construction site. Thus, the essential for the design function of the recessed light reflector element can be used only when all dirt-causing work on the site are completed. In other words, the assembly order of the parts of the recessed luminaire can be adapted to the sequence of operations by the different trades on a construction site.

Due to the modular structure, moreover, storage can be simplified. Finally, the timing of the decision in a customer, which design or which photometric properties to provide the recessed light, be delayed far back. Thus, completely different light heads can be fixed with the aid of the receiving element in a simple manner to wall side already set mounting elements.

It should be emphasized in particular that both the attachment of the receiving element to the mounting element and the attachment of the reflector element to the receiving element can be accomplished without tools.

In the following, the built-in element 12 will first be described in more detail:

evidenced Fig. 1 For example, the mounting element 12a has a substantially annular structure. The wall 24 forms an axially short tube section. On re Fig. 1 lower free end portion of the wall 24, a radially outwardly projecting flange-like collar 23 is arranged. This engages in the case of a ceiling-side installation, the marginal edge of the ceiling-side mounting hole and thus forms a structurally clean luminaire finish.

The mounting element 12 comprises according to Fig. 1 two expansion spring elements 22a, 22b, which is what looks best Fig. 4 can be seen, tangentially protrude. The two expansion spring elements 22a, 22b advantageously have a tooth structure 77 on their respective underside.

The mounting element 12a is used for immediate fixing to a false ceiling, for example on a plasterboard. For this purpose, the mounting element 12a - in the case of a ceiling-side mounting - used from below into the ceiling-side mounting hole. The ceiling-side mounting opening, which is not shown in the figures, has an inner diameter which is greater than the outer diameter SA of the mounting element 12a (see. Fig. 7 ). The outer diameter SA is measured at the widest point of the mounting element 12a. This widest point is according to the installation element Fig. 7 the attachment region 78 of the expansion springs 22a, 22b on the wall 24th

The collar 23 provides an outer diameter SK, which projects beyond the outer diameter SA and the inner diameter of the wall-side installation opening, not shown. The top 79 of the flange collar 23 is in the installed state of the mounting element 12a on the underside of the ceiling wall.

It should be noted that during the insertion of the mounting member 12a in the ceiling-side mounting opening, the expanding springs are biased radially inwardly and are pressed manually inward to allow passage of the mounting element 12a in the wall-side mounting hole. After the insertion of the installation element into the wall-side installation opening, the expansion springs can extend radially.

Subsequently, the mounting element can be rotated for the purpose of fixing to the ceiling until the plasterboard is clamped between the spreading spring and collar. The provided with a toothing 77 bottom of the spreading springs 22a, 22b is in the installed state at the top of the partition on. The spreading springs 22a, 22b and the teeth 77 are designed so that the same installation element 12a can be used to cover different wall thicknesses of the false ceiling.

As an alternative to the fixing means 22 provided by spreading springs of the variant according to FIG Fig. 1 has the mounting element 12b according to Fig. 2 Holding plates 28a, 28b, 28c. These perforated plates 28a, 28b, 28c, which are provided with numerous openings, have been inserted through slots 80a, 80b, 80c, 80d in the wall 24 of this installation element 12b. The installation element 12b according to Fig. 2 has a cleaning edge 29, in particular in the sectional view according to Fig. 12 becomes clear. The cleaning edge 29 allows a plastering of the wall-mounted installation element 12b. This is fastened by fasteners, such as nails or screws, first cover side. For this purpose, a choice is first made, through which the respective slots 80a, 80b, 80c, 80d, the perforated plate 28 is inserted therethrough. In this way, the radial distance of the sheet 28a can be adjusted to the cleaning edge, in adaptation to the site-specific default. The Perforated plates 28 are held captive on the on the mounting element 12b.

Another variant of the component installation element shows Fig. 3 in the form of the annular mounting element 12c. Here are provided as fixing means holding bracket or blocks 30a, 30b, 30c, which are each pivotable about a pivot axis 31, fixed to web-like extensions 81a, 81b, 81c. The projections 81a, 81b, 81c carry on their outside a step assembly 32 with a series of ratchet teeth.

The mounting element 12c according to Fig. 3 also has a radially outwardly projecting retaining collar 23. In accordance with the embodiment of Fig. 1 the mounting element 12c is the Fig. 3 used in a cover-side mounting hole until the top of the collar 23 abuts the underside of the false ceiling. During this insertion process, the brackets 30a, 30b, 30c are pivoted about their respective pivot axis 31 in a radially inner position in which they protrude into the interior of the mounting element 12c.

After the insertion of the mounting element 12c in the cover-side mounting hole, not shown, the three brackets 30a, 30b, 30c are successively pivoted about their respective pivot axis 31 radially outward until, for example, in Fig. 3 reached to the bracket 30c position shown. Subsequently, by manual pressure exerted on the upper side 82 of the respective bracket this along the row of stages 32 are axially displaced until it strikes with its respective bottom 83 at the top of the false ceiling, not shown. For example, the in Fig. 3 with 30a designated bracket such, axially moved down Position in which he is attached to such, in Fig. 3 Not shown false ceiling could rest with its underside at the top.

The distance B between the bottom 83 of the bracket and collar 23 corresponds, at a maximum downward state of the bracket, the wall thickness of the false ceiling.

When all three brackets 30a, 30b, 30c are moved to their radially lowest position, the so-called stop position, the mounting element 12c is securely fixed to the false ceiling.

Each bracket 30a, 30b, 30c has an in Fig. 3 merely indicated release lever 33, which allows a solution of the bracket from the respective latching step and in particular its rearward displacement from a radially lower position, such as in accordance with the bracket 30a in Fig. 3 in a radially uppermost position, such as in accordance with the bracket 30c in Fig. 3 allowed.

All three variants of the mounting element 12 according to the FIGS. 1 to 3 is common that extends from the respective wall 24 radially inwardly projecting an annular collar 25. This has a continuous circumferential top 26, whose function will be described later. Further, the annular collar on its opposite, lower side a number of axially projecting ribs 27a, 27b, 27c, whose function will also be described later.

Next is the different variants 12a, 12b, 12c of the mounting element in common that these matching dimensions of Inner diameter Di of the annular collar 25 have, as is made Fig. 7 is apparent.

Finally, the outer diameter SA of the different variants 12a, 12b, 12c of the mounting element in the different variants may be the same or substantially the same.

In addition, each of the three mounting elements has a uniform slot 43 in the wall 24, the function of which will be explained later.

A selection of the respectively suitable mounting element 12 will make the skilled person depending, for example, on the desired ceiling, as well as depending on which type of completion - plastering or projecting collar - is desired.

Based on Fig. 8 Now, a first variant 13a of an annular receiving element will be described.

Fig. 8 makes it clear that the receiving element 13a is formed by a substantially axially short, substantially tubular element, with an annular cross-section wall 35. Regarding Fig. 8 extend axially upward two strut-like extensions 36a and 36b, which serve for the attachment of brackets 41. Such headband 41a, 41b shows, for example, the assembly of Fig. 14 and Fig. 15 , By means of an in Fig. 15 For example, a fixing of a preferably consisting of metal retaining clip 41 a, 41 b to a mounting hole 85 of a strut 36 a, 36 b done with 84 fastener.

It should already be mentioned that, as the building unit of Figures 14 and 15 shows, a determination of the headband can be done both in rigid connection to the receiving element 13a, or alternatively, as in particular the Figures 36 and 22 show, a pivotable attachment of a retaining clip 41 can be made to the strut 36, wherein the mounting opening 85 forms a pivot axis 42 for the corresponding headband and attached to the headband lighthead 15.

The annular receiving element 13a according to Fig. 8 moreover comprises a radially outwardly projecting outer collar 34.

This outer collar is an essential feature of a uniform interface, which is kept the same in all the different variants of a receiving element 13.

The outer diameter Da of the receiving element 13 at its widest point, in the region of the outer sides of the outer collar 34 is in the Figures 10 and 11 shown. The outer diameter Da is dimensioned such that it is at least slightly larger than the inner diameter Di of the associated mounting element 12 (see. Fig. 4 ).

In other words, an axial insertion movement of a receiving element 13 into a wall-mounted installation element 12 is limited by abutting the upper side 38 of the outer collar 34 on the underside 39 of the inner collar 25. These geometric relationships, for example, shows the sectional view of Fig. 12 ,

The receiving element 13a according to Fig. 8 moreover, each offset by 120 °, three pairs of spring tabs 37a, 37b. These spring tabs 37 are integrally molded cohesively to the formed of plastic injection molded part receiving ring 13a with.

As a result of the left free spaces 86a, 86b, 86c, a pivotability of the spring tabs 37a and 37b is achieved by the twistable web portions 87a and 87b, which thus form the pivot axis.

As a result of an insertion movement of the receiving element 13a into a mounting element 12b, the upper side 88 (see FIG. Fig. 12 ) of the corresponding spring tab 37 in contact with a corresponding Eckwandungsbereich 89 of the wall-mounted mounting member 12b, so that the spring tabs 37 perform a radial inward movement until the locking nose-like end 90 of the respective spring tab 37 is passed past the inner collar 25 of the mounting member 12b and on the upper side 26 rests.

This installation state is shown in the schematic sectional view of Fig. 12 ,

Further insertion of the receiving element 13a in the wall-mounted mounting element 12b is prevented by the radial overlap of outer collar 34 and inner collar 25. At the time of the striking of the two collars 34, 25, the locking nose end 19 is past the inner collar 25.

If this attachment position is reached, the receiving element 13a is securely held on the mounting element 12b.

As already described above, the different variants of the installation element 12 all have an identical geometry the interface, in particular an identical design of the inner collar 25. This makes it clear that the same receiving element 13a can be fixed to different variants of a mounting element 12.

Fig. 13 illustrates that with the aid of a tool, such as a screwdriver 40, a radially inwardly directed displacement of a spring tab or a pair of spring tabs 37a, 37b can be made to release the receiving element 13 of the wall-mounted mounting element 12.

In an alternative variant, not shown, a tool-free solution of the receiving element 13 can be carried out by the wall-mounted installation element 12.

It is crucial that a dimensioning and design of the spring tabs 37 takes place in such a way that on the one hand an effortless insertion of the receiving element 13 in the mounting element 12 possible and secure attachment is guaranteed. On the other hand, the connecting means must be such that even heavy light heads, for example, using cast-iron housing parts 19, are securely held without the receiving element unintentionally detached from the mounting element 12.

The connecting means described above for the detachable connection of a receiving element to a mounting element are to be understood merely by way of example with reference to the three pairs of spring tabs 37 in cooperation with the radially inwardly projecting annular collar 25 on the mounting element. It depends neither on the number nor on the positioning of the spring tabs in particular. Instead of the three described pairs of spring tabs can also be more or less spring tabs, if they are designed to be used.

It would also be conceivable to make a geometric reversal of collar and spring tab, such that the spring tabs on the mounting element and a corresponding collar or a material area providing a retaining surface for the spring tabs is arranged on the receiving element.

The connecting means, however, essential to the invention provide a mechanical interface between receiving element and mounting element, which is always the same design for different mounting elements when using the same receiving element.

Another essential interface mechanical type between the receiving element 13 and the mounting member 12 will now be with reference to the embodiments of FIGS. 23 to 25 be explained:

The connecting means described above for the releasable fixing of the receiving element to the mounting element in the form of the spring tabs are designed such that in the assembled state of receiving element and mounting element, the receiving element is rotatable relative to the mounting element. This rotation is ensured by the fact that the top 26 of the inwardly projecting annular collar 25 of the mounting element acts as a sliding bearing surface for the bottom or the locking lug 90 of the spring tabs 37.

The receiving element is in principle free to rotate in the case of an annular training in cooperation with a circular-shaped mounting element.

However, means are advantageously provided which provide a rotation limit in both directions of rotation. The reason for such a desired rotation limitation is the fact that the lighthead is provided with electrical connection lines, which may be exposed to prevent damage, possibly a limited rotation of the lighthead.

To prevent excessive rotation of the previously described, provided on the mounting member 12 slot 43 is provided, which cooperates with a control pin 47 on the receiving element 13.

evidenced Fig. 23 is a control pin 47 integrally-materially firmly connected via a connection region 49 with the wall 35 of the receiving element 13. As a result of free cuts 48 axial mobility is achieved because a Biegeachsbereich 50 forms, which allows a slight pivoting of the control pin 47 about the bending axis 50.

The control pin 47 protrudes from the receiving element 13 radially outward, as for example Fig. 10 makes it clear. In the assembled state of receiving element 13 and mounting element 12 of the control pin 47 is located with its radially outer side on the inside of the wall 24 of the mounting element or this is in any case immediately adjacent.

A rotational limit in the first rotational sense is achieved by an inwardly projecting from the wall of the mounting element 12, in Fig. 24 only dashed lines indicated stop wall 91. This cooperates with the control pin 47 such that a further rotational movement of the receiving element relative to the mounting element in the sense of relative movement of the receiving element relative to the Fig. 24 to the left, is prevented.

In the other sense of rotation, starting from the state of Fig. 24 the control pin 47, together with the receiving element first carry out an approximately 355 ° comprehensive movement and are guided along the path BW. Subsequently, he encounters the ramp 44, which is arranged radially inwardly of the slot 47 and forces the control pin 47 to leave its trajectory BW. Finally, the control pin 47, like this Fig. 25 shows - are displaced axially along the ramp 44 due to further rotation of the receiving element. That related to Fig. 25 right end 45 of the slot 43 provides the second stop surface ready and prevents - after striking - a further rotational movement of the receiving element relative to the mounting element in terms of further movement of the receiving element relative to the Fig. 25 to the right. It should be noted that Fig. 25 not yet the stop position, but only an intermediate position, just before reaching the stop shows.

It should also be clarified that due to the fact that the two abutment surfaces 91 and 45 are axially spaced from each other, a rotation of the receiving element is made possible relative to the mounting element by an angle which is slightly larger than 360 °. For example, a 365 ° allowable rotation is intended. This can actually be set any possible rotational position, while also ensuring that your damage to the electrical leads takes place.

In other words, due to the Axialversatzes and circumferential offset of the different stop positions of the Control pin 47 a 360 ° slightly exceeding rotation of the receiving element can be achieved relative to the mounting element.

It should also be noted that in an alternative embodiment of the invention, which is not shown in the figures, instead of the slot 43, a control surface arrangement on the wall 24 of the mounting element is provided, which also allows a described axial displacement of the two stop positions of the control pin 47. A window-like slot, as shown in the embodiments and described above, is not essential.

It is also essential here that a defined interface is created between the receiving element and the built-in element, which makes it possible to achieve rotational stop positions of both rotational grooves.

In the following, based on the embodiments of the FIGS. 14 to 18 First, a handling unit 92 will be explained, which comprises a receiving element 13a, headband 41 a, 41 b and a light head 15.

The headband 41 a, 41 b may be made of metal and fixed to the web-like projections or struts 36 a, 36 b of the receiving element 13, for example, screwed or riveted, be. It can be attached to the same receiving element 13a optionally different headband, for example, different lengths or differently stable formed headband.

The headband 41a, 41b are z. B. over in Fig. 14 indicated fasteners 92a, 92b bolted to the housing part 19. The housing part 19 will be described in detail later. It is an existing example of cast iron or aluminum, with numerous cooling fins provided component on which the bulb, the socket for the bulb and the upper reflector 21 can be set. An assembly of the handling unit 92 takes place in the factory. In this case, a composition of the individual components, comprising components of the group light head 15, upper reflector 21, receiving element 13 (including headband 41) is composed in such a way that the lamp can achieve the desired lighting function. Not shown in Fig. 14 and in the following figures, the electrical connection lines for the light head 15th

The factory pre-assembled handling unit 92 can be inserted into the mounting element and clamped to it. Previously, an electrical connection of the connecting cable, which in Fig. 14 not shown, be made with the wall already laid electrical line.

The different embodiments of the FIGS. 19 to 22 are intended to illustrate that a plurality of different handling units 92a, 92b, 92c, 92d is available for the same mounting element 12 fixed to the ceiling wall 93, each of which can optionally be fixed to the same mounting element 12. The FIGS. 19 to 22 make it clear that a definition of the handling unit 92 only takes place when the mounting element 12 is already fixed on the wall side.

For explanation it should be noted that the FIGS. 19 to 22 each show a mounting situation in which the handling unit 92 is already connected with its electrical connection line 94, but still loosely protruding from the mounting element.

Further illustrates the crowd of FIGS. 19 to 22 completely different light heads 15a, 15b, 15c, 15d.

The different design of the light heads can be justified, for example, that in a light head 15, for example, an operating device for the light source is integrated, which is not shown, or, as this Fig. 21 indicates that such an operating device is connected upstream of the light head 15c.

Next, like this Fig. 22 shows the lighthead 15d pivotally about the pivot axis 42 to the receiving element 13b arranged to allow individual alignment and positioning of the lighthead. Thus, different desired light distributions on the surface of the building to be illuminated, for example a floor surface or a side wall surface of a building, become possible.

Finally, the crowd illustrates the FIGS. 19 to 22 but also that different light heads 15a, 15b, 15c, 15d can interact with the same receiving element 13a. Consequently, different lights 11a, 11b, 11c, 11d, 11e are composed of different variants of components of the modular construction system 10 according to the invention.

In the following, the interaction between a reflector element 14 and a receiving element 13 will be explained:

The reflector element 14a consists for example of pressed aluminum and has a wall 54, which is mirrored on its inside preferably high gloss. While the reflector element 14b according to Fig. 33 essentially is rotationally symmetrical, is in the reflector element 14a according to Fig. 28 a vertex portion cut off obliquely, so that in particular from the side view Fig. 29 resulting unbalanced training results.

The reflector element 14 has an edge region 55, which is achieved by beading. The reflector element is, as the particular FIGS. 31 and 32 show, twice folded in the free edge area and finally rolled inwards.

The peculiarity here is that the reflector element 14 can cooperate with the receiving element 13 tool-free, while achieving a kind of snap-ring connection. The receiving element 13 has as a variant cross-mechanical interface three 120 ° circumferentially offset arranged spring tabs 59a, 59b, 59c, the respect to Fig. 9 lower free edge region of the wall 35 are arranged. These three spring tabs 59a, 59b, 59c can engage in the interior 95 of the beaded edge region 55. The spring tabs 59a, 59b, 59c, as can be seen in particular from the sectional view of Fig. 34 results, equipped with a retaining lug 96, which can be engaged behind by the free edge region 97 of the beaded edge 57. Fig. 34 shows this situation only schematically.

The special feature is that the reflector element 14 is only attached to the receiving element 13 when the receiving element 13 is already fixed to the mounting element 12. Thus, the reflector element can be mounted as a last element in a simple manner.

The arrangement of spring tabs 59 allows a tool-free fastening and a tool-free release. In this case, further advantageously a simple axial movement for fixing the reflector element to the receiving element can be used.

Incidentally, a determination of the receiving element on the mounting element with the mere aid of an axial insertion movement is possible.

As can be seen in particular Fig. 34 results, the bottom 61 of the free edge 55 of the reflector element is substantially flush with the bottom 60 of the retaining collar 23 of the mounting member 12 in the assembled state. This achieves a flush arrangement. If instead of a built-in element with retaining collar 23, a mounting element 12 is used with plaster edge 29, the bottom 61 of the edge 55 of the reflector element 14 is mounted flush with the trim edge 29 in the assembled state. The concept of conciseness of this arrangement also includes, as this Fig. 34 indicates slight returns.

The FIGS. 28 and 29 let recognize a recess 56 on the free edge 55 of the reflector element. The recess 56 can cooperate with the coding end 58 of the slide element 51.

The FIGS. 26 and 27 show a schematic representation of an interior view of a connection region between receiving element and mounting element. On the receiving element, the slider element 51 is set axially displaceable. The slider element 51 is between the in Fig. 26 indicated axially lower and the in Fig. 27 indicated axially movable upper position. The slider 51 has two slide cams 52a, 52b, the form-fitting in corresponding Bays 53a, 53b on the underside of the inner collar 25 can engage the mounting element 12.

The slider element 51 is in the in Fig. 26 shown lower position, the receiving element 13 is freely rotatable relative to the mounting member 12. If the slider 51 by manual attack on the actuating surfaces 98 from the position according to Fig. 26 in the position according to Fig. 27 method, the control cam 52a, 52b engage in the spaces 52a, 53b of the ribs 27a, 27b such that the receiving element is prevented from rotating relative to the mounting element. As a result, therefore, the selected rotational position of the receiving element can be permanently fixed relative to the mounting element.

The re Fig. 26 Lower end 58 of the slider element 51 can cooperate with the Codierausnehmung 56 at the edge 55 of the reflector element 14. In particular, in the case of reflector elements 14 which generate a non-rotationally symmetrical light distribution, the reflector element 14 can be positioned with its coding recess 56 relative to the receiving element 13 in such a way that the coding end 58 of the slide 51 engages in the coding recess 56.

With reference to the embodiment of Fig. 37 should first be clarified that a recessed luminaire 11, which is composed of components of the module system 10 according to the invention, at least in some variants may also include a diffuser element 62. The diffuser element 62 is fastened to the reflector element 14 by retaining means, not shown in detail, and together with the latter forms a handling unit.

The reflector element 14 is fixed in the manner described above in the context of a last assembly step together with the diffuser element 62 on the receiving element 13 already fixed to the mounting element 12.

With reference to the Figures 38 and 39 is presented a further element of the module system 10 according to the invention: Fig. 39 shows in perspective in solo representation an adapter element, which serves, for example, to provide a shadow gap 99. The adapter element 16 is annular and wiest - in analogy to the geometric design of the circular receiving element 13 - three pairs of spring tabs 37, which are arranged circumferentially offset by 120 °. Adjacent to the pairs of spring tabs, an annular, annular end face 100 is provided, which corresponds in terms of its geometric configuration of the top 36 of the outwardly projecting annular collar 34 of the receiving element.

Like the right half of the Fig. 38 indicates, the upper side 100 of the axial portion 101 of the adapter element 16 cooperates with the inwardly projecting annular collar 25 of the mounting element 12a.

The adapter element 16 also has - in analogy to the arrangement of an annular collar on the mounting element - an inwardly projecting annular collar 63. This has an upper side 26, which corresponds to the top 26 of an inwardly jumping annular collar 25 of a conventional mounting element. In addition, axially extending ribs 27a, 27b are provided on the underside.

In other words, the adapter element 16 mimics both the interface of a conventional receiving element to the Built-in element, on the radial outer side, after. At the same time, however, the adapter element 16 also imitates in the form of the annular collar 63 the mechanical interface of a mounting element to a receiving element.

While the module system 10 according to the invention keeps the individual components 12, 13, 14 in different sizes, the adapter element 16 can ensure that a receiving element of a smaller size can cooperate with a mounting element of a larger size. The adapter element 16 thus mediates between two components of the module system according to the invention of different sizes.

It is evident that the embodiments of the Figures 38 and 39 the possibility of providing the adapter element 16 with a downwardly double-walled design with an axial section 101 and a second axial section 102, which form a shadow gap 99 between them. Such a design is desirable in certain applications.

Alternatively, it is also possible to provide the adapter element 16 with the closed bottom. Finally, in the embodiment of the Fig. 38 a shadow gap 99 providing annular space also for irradiation of accent light, for example, for a LED decorative light ring used.

As evidenced by the embodiment of Fig. 40 a square, annular receiving element 17a is shown. This comprises - in analogy to the embodiment of an annular receiving element 13 - a pair of struts 36a, 36b, with respect to their geometry identical or similar to the struts of an annular receiving element are configured.

In particular, the struts 36a and 36b of the square receiving element 17a are dimensioned and spaced from each other such that identical retaining clips and the same light heads can be attached both to a square receiving element and to an annular receiving element.

The square receiving element 17a has on two opposite sides in each case two pairs of spring tabs 37a, 37b, which no longer need to be explained in detail, since their function and operation analogous to the function and operation of the spring tabs 37a, 37b corresponds to the annular receiving element.

The square receiving element can with a square mounting element 20a according to Fig. 56 cooperate. On the square mounting element 20a in turn an inner circumferential arrangement of an inwardly projecting annular collar 25 is provided. The spring tabs 37a, 37b come after insertion of the square receiving element in the already wall side fixed mounting element 20a, on the upper side 26 of the inner collar 25 for concern.

Fig. 56 shows the square mounting element with a cleaning edge 29. The alternative variant according to Fig. 57 shows an outwardly projecting collar. Also makes the sequence of Figures 56 and 57 clearly that - in analogy to the annular configuration of a mounting element - again different variants of a mounting element to be provided for fixing to the false ceiling can. Inter alia, perforated plates 28a, 28b or mounting brackets 30a, 30b can again be provided as fixing means.

At this point is also on the variants of Figures 58a and 58b In some applications, it is desirable to arrange a group of several recessed luminaires directly next to each other. For this purpose, it is advantageously possible to resort to a further alternative installation element which has a doubling or multiplication of conventional installation elements. Thus, the mounting element 73a according to Fig. 58a of two conventional mounting elements 20a according to Fig. 56 be composed. Only in one of these installation elements, a wall must be separated and then by fastening such as welding, gluing or the like, the existing three side walls frame-like arrangement of the mounting element are attached to the second mounting element.

Again, it is possible, both in a double mounting element 73a risen conventional mounting elements 20a, 20b each separately with receiving elements 17a according to Fig. 41 to equip.

The double arrangement of a built-in element 73a according to Fig. 58a For both partial insert fields now has a common frame wall 74a or in one embodiment of the Fig. 58b a common wall 74b.

In a further, not shown variant of a double arrangement of a particular rectangular mounting element, similar to the mounting member 73 a of Fig. 58 , Can a production of such a rectangular mounting element of two square mounting elements 20a according to Fig. 56 respectively. For this purpose, two square mounting elements 20a according to Fig. 56 machined as follows: On each side, so on a frame portion, all of the wall 24 of the mounting member 20a protruding elements, such as the retaining collar or a fastener, removed, for example, milled, so that the outer surface of the wall 24 on this page through is smooth. The two correspondingly machined sides of the two mounting elements are - together aligned - attached to each other, for example by gluing or ultrasonic welding. In this way, a substantially rectangular, two square mounting holes exhibiting double mounting element is provided.

By the described removal of protruding areas on the two, in the attached state juxtaposed side walls, a special gauge can be achieved: Thus, two adjacently arranged, and used in the two openings of the rectangular mounting element square reflector elements butt against each other. Thus, a special, creative conclusion can be achieved.

The interaction of a square mounting element with a square receiving element is still briefly on the basis of Fig. 59 illustrates: It can be seen that the locking lug 90 of the corresponding spring tab 37a rests on the top 26 of the inwardly projecting annular collar 25 and projects beyond this and engages behind.

Furthermore, it is clear that a square-shaped receiving element has a circumferential annular end face 38 (see also Fig. 41 ), which overlaps with the inwardly projecting annular collar 25 of the square mounting element in the assembled state and Thus, a stop surface for an insertion movement of the square receiving element 17a in the wall side already fixed mounting element 20a offers.

Finally, it should be noted that even with the square variant of an attachment of a reflector element 18 according to Fig. 45 directly on the receiving element 17a according to Fig. 41 he follows.

For this purpose, the square receiving element 17a window-like openings 64a, 64b, which can be penetrated by spring clamping elements 65a, 65b. Fig. 46 and 47 show in view or in section that the spring clamping elements have a radially outwardly arranged locking lug 103 which can pass through the corresponding window 64a, 64b in the inserted state of the reflector element 18 in the receiving element.

Even with the square mounting element so far initially the ceiling-side determination. Subsequently, the receiving element 17a can be used together with the light head. Only in a final step is it necessary to fix the reflector 18 on the receiving element 17a.

Even with the square version of the modular system is proven Fig. 59 it can be seen that the receiving element 17a mounted on the installation element 20b rests flush with its underside or slightly springs back upwards.

Finally, it should be noted at this point that the invention with its numerous variants of the present patent application is described only with reference to a recessed luminaire designed as a recessed luminaire. It is the expert, however understand and see that the patent application is not limited to recessed ceiling lights. It is equally possible and is encompassed by the present invention, the described principle in the field of recessed floor luminaires or the side wall recessed lights of a building or in connection with outdoor spaces such. As walkways, parking areas or the like to apply.

Below is on the Figures 48 and 49 These show two different variants of a housing part 19a or of a housing part 19b as an essential component of a light head 15.

The two housing parts 19a, 19b are formed of cast-iron steel or a comparable material and are used in particular for the removal and transfer of heat, which is generated by the illuminant attached thereto. For this purpose, the outside of the housing part 19a, 19b on numerous cooling fins 104.

While the outer dimensions of the housing part are the same or similar, the height H _{1 of} the housing part 19a is significantly lower than the housing height H _{2 of} the housing part 19b. This is due to the fact that the housing part 19b provides an overall greater cooling capacity, because of the larger volume and a larger mass of the housing part 19b, for example, because a lamp is attached to the housing part 19b, which brings a greater power consumption.

The FIGS. 50 and 51 show the respective bottom views of the housing parts 19a, 19b. The same goes for the FIGS. 52 and 53 showing the housing parts with sockets and lamps attached to them.

With reference to the Figures 50 to 53 It is clear that both housing parts 19a and 19b each have a pair of holes 28a, 28b, which have a same bore spacing BM. This provides a mechanical interface for connection to the retaining clips 41 of the receiving element. Since the bore spacing BM is always the same, different housing parts 19a, 19b can always be fixed to the same receiving element 13 or 17.

The holes 68a, 68b, and the other, to be explained later holes in the housing parts 19a, 19b are z. B. provided with an internal thread and serve to receive mounting screws.

The housing part 19a has a plurality of further fastening bores, namely the bores 69a, 69b, 69c, 69d, 69e, 69f, 69g. The housing part 19b has according to 51 a series of mounting holes 69a, 69c, 69g, 69h, 69i, 69j.

It is clear that the two housing parts 19a and 19b also comprise identical fastening bores insofar as are designated 69a and 69b on the housing part 19a and 69a and 69c on the housing part 19b. Also, these two mounting holes have a same bore spacing, which serve to establish a strain relief strap and their screw.

Finally, the housing part 19a has a first pair of holes 69c, 69f and a second pair of holes 69d and 69e, which can optionally be used for mounting different lamp sockets. Fig. 52 shows that the fixing holes 69c, 69f are used to fix the socket part 70a. At this version part of the lighting means, ie the lamp 71 a, attached.

Not shown is the further variant, in which the mounting holes 69 d, 69 e are used to screw the holder for another, not shown light source.

In the embodiment of the housing part 19b according to 51 Again, a plurality of mounting holes are provided, which are designated 69g, 69h, 69i and 69j. These are two pairs of mounting holes, which can be used optionally for connecting different sockets for different light sources. Fig. 53 and Fig. 55 show the housing part 16b according to 51 to which a lighting means 71 b is screwed with an associated socket 70 b. The tightening was done so in the mounting holes 69g and 69j.

In an alternative, not shown embodiment of the housing part 19b 69h and 69i another, not shown socket is fixed to the other pair of mounting holes.

In other words, on the same upper housing part (19a, 19b) optionally a different socket element 70 and another light source 71 are screwed.

The FIGS. 60 to 63 show in a partially cutaway view ( Fig. 60, Fig. 61 ) or in the lower view ( Fig. 62, Fig. 63 ) Light heads 15d, 15e, which are formed differently. It is conceivable that both light heads 15 d, 15 e use a same housing part 19 c.

The special feature here is that different top reflectors 21a, 21b are attached to the same housing parts 19c. The two upper reflectors 21 a, 21 b are formed as faceted reflectors and have a substantially cup-shaped basic shape and a highly reflective, designed with numerous facets inner surface.

The Figures 60 and 61 let recognize that the two reflectors 21a, 21b have different dimensions. The attachment of a reflector 21 by means of second screws 76a, 76b on a retaining plate 75. A special feature is that the distance between the two screws 76a, 76b is kept the same even with different dimensions of a top reflector 21a, 21b. This provides a mechanical interface for connection to the same retaining plate and the same upper housing part 19c in the case of different, faceted upper reflectors 21.

Based on Fig. 34 will now be made clear that due to a special arrangement of wall regions of reflector element 14, receiving element 13a and mounting element 12a light exits only through the light exit opening 105 of the reflector element 14, and not laterally outside thereof.

Starting from Fig. 34 is quite conceivable that light proportions approximately along the direction of the arrow P in Fig. 34 from a position above the reflector element 14 can enter into the annular space Ri. However, these light components can not escape outside of the light exit opening 105 from the reflector. The wall portion W _{1 of} the receiving element 13a and the wall portion 54 of the reflector element 14 are aligned with each other in such a way that the light is prevented from escaping from the lamp. This ensures in particular that in the transition region between the reflector edge 55 and the in Fig. 34 not shown ceiling is a light-tightness. The a structure according to Fig. 34 having recessed luminaire 11 allows light to emerge only in the area of the light exit surface 105 of the reflector 14 from the lamp.
