Description

The invention relates to a module construction system for a recessed luminaire.

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 to develop, based on the known prior art, a module construction system for recessed luminaires, which permits the use of a high 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.

Built-in element and receiving element are annular, for example, annular or square or rectangular. Built-in element and receiving element are matched with respect to their basic shape. 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.

Alternatively, the fixing means may comprise perforated plates projecting radially outwards from the mounting element. The perforated plates allow attachment of the mounting element to a ceiling underside, for example by nails or perforated pins.

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.

In general, different variants of the mounting element for the same size, d. H. especially with the same inner diameter, may have different fastening means that allow a determination of the mounting element on different types of ceiling 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 in Essentially annular. A first variant of a receiving element has two axially extending struts, on which retaining clips are fastened for fastening a lighthead. A first variant of the receiving element has axially short struts, and a second variant of the receiving element has axially elongated struts. 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. On the receiving element, a radially outwardly projecting outer collar may be provided, which covers with the inwardly projecting annular collar of the mounting element in the assembled state.

To carry out a fastening of the receiving element to the mounting element, the receiving element can be mounted on the wall-side already fixed mounting element, in which it is passed through the provided by the mounting element insertion. Here, the spring tabs can be biased radially inwards and then engage in their radially extended end position. The top of the radially outwardly projecting annular collar on the receiving element may come during the insertion of the receiving element into the mounting element with the underside of the radially inwardly projecting annular collar on the mounting element in contact, so that a plant situation is achieved. As a result, the insertion movement of the receiving element is axially limited in the mounting element.

The receiving element further comprises means which allow a releasable attachment of a reflector element to the receiving element. Preferably, a reflector element by providing a clip connection, in particular in the manner of a Ringschnappverbindung, axially fixed to the receiving element.

Further preferably, the reflector element is releasably secured to the receiving element without tools. Also, the receiving element can be set releasably without tools on the mounting element.

The module construction system according to the invention can also contain further interfaces which allow additional use of many identical parts. For example, different light heads can be attached to the same receiving element. On the other hand, different receiving elements can be attached to the same light head. The associated interface can be provided by two holes at the free end of the headband, where the light head is fixed relative to the receiving element or screwed.

Finally, a light head can be provided which has a housing part, on which different sockets for different lamps can be fixed. For this purpose, the housing part may comprise two or more pairs of fastening domes, a first pair of fastening domes being used for fastening a luminous means and a socket provided for this purpose, and a second pair of fastening domes or fastening screw holes used for fixing a second lamp socket.

Advantageously, the recessed luminaire is designed as a ceiling luminaire and illuminates a floor surface or a side wall surface of a building or part of a building. This allows a particularly simple installation of the lamp, since first the mounting element is fixed to the wall side and then, for example, a plastered the wall can be done, such that the mounting element, which may for example have a plaster edge, is plastered. Only when these, often dirt or dust-causing activities have been completed, and other trades, such. As the electrician to act on the site, the receiving element can be used in the mounting element, and advantageously without tools. An attachment of the light head is carried out on the receiving element usually already at the factory. At the same time, the electrical system can also be connected to the lighthead.

It is advantageous if the receiving element together with the light head, forming a handling unit, is inserted into the installation element.

If the electrical system is connected, the reflector element can be fastened to the receiving element in a last step. This attachment is preferably done without tools.

Both the attachment of the receiving element to the mounting element and the Attachment of the reflector element to the receiving element is carried out by performing a full axial movement of the respective element relative to the wall-mounted detained installation element.

According to a further embodiment of the invention, the same receiving element with different variants of the mounting element is connectable. Further advantageously, the same receiving element with different variants of the reflector element is connectable.

The connectivity of the same receiving element with different variants of the mounting element takes into account that a defined interface between receiving element and mounting element is provided. This interface can be accomplished by, for example, three spring tabs or spring tab pairs (in the case of an annular receiving element) or four (in the case of a square receiving element). In an annular receiving element, the spring tabs can be integrally formed integrally with the receiving element. The spring tabs can interact with an inner annular collar on the mounting element. Different installation elements can different end edges, z. B. plaster edges or protruding collar having. However, they always have, with the same inner diameter, an inwardly projecting annular collar, the upper side of which can cooperate with a retaining surface of the spring tongues.

Different variants of the reflector element can ensure different light distributions, but are always connected to the same receiving element. For example, a reflector element may have a flanged free edge which engages over three strip-like projections on the receiving element. A first reflector element may provide a first light characteristic and a second reflector element may provide a second, different light characteristic. Both reflector elements can be fixed to the same receiving element, since the corresponding interface is defined.

Further advantageously, it is provided that one and the same mounting element with different variants of the receiving element is connectable. Thus, for example, one and the same installation element cooperate with a first receiving element, which axially short held struts, and cooperate with a second receiving element having axially elongated struts. Depending on the choice of the desired light head different recording elements are selected, this selection is to be made only when the mounting element is already set on the wall side, since the different variants of the receiving element can be inserted into the mounting element and fixed to this.

Finally, the same reflector element can be connected to different variants of the receiving element. Thus, a reflector element having a predetermined light characteristic can be connected to both a receiving element, which has axially elongated struts, as well as be connected to a receiving element, which has axially short struts held.

Further advantageously, it is provided that the light head has an additional reflector element, in particular a top reflector. In a ceiling light, an arrangement may be provided with a top reflector and a sub-reflector. The upper reflector is fixed to the lighthead and the sub-reflector is fixed to the receiving element.

In the case of a bottom-side installation, a reverse arrangement is provided. The upper reflector is basically the reflector closer to the light source, and the sub-reflector is basically the reflector further away from the light source.

In a first variant of the mounting element, a collar is provided, which engages in the fastened state, the edge of a mounting hole in the wall. This decor collar takes into account that a mounting of the mounting element has been made on the wall when the wall is already plastered.

In a further variant of the mounting element, a cleaning edge is provided instead. This allows a plastering of the mounting element and a determination of the receiving element on the mounting element, if the latter is already plastered.

Variants of the mounting element include mounting elements with different fixing means. Fastening means of the first type can have expanding springs, fastening means of the second type can have perforated plates, and fastening means of the third type can have axially movable holding blocks. Other types of fixing agent are possible.

It is crucial that different mounting elements with different fixing means each have a same, defined interface to the receiving element. These are in particular constant internal diameters and the arrangement of an inwardly projecting annular collar, wherein different Variants of the mounting element of the same size basically provide a same geometry of the inner ring collar.

Further advantageously, it is provided that the mounting element is formed substantially in the manner of an axially held short pipe or pipe section. Thus, a material-saving training can be achieved. Also, the receiving element is advantageously formed substantially in the manner of an axially held short tube or pipe section.

Further advantageously, it is provided that from the inside of the mounting element an annular collar protrudes inwards. This collar is given in all variants of a mounting element of a size in terms of its dimensions, in particular the inner diameter specified. The collar allows a simple way the arrangement of a rotary bearing surface for the receiving element and the provision of axially elongated ribs on the bottom.

It is advantageously provided that the annular collar has an over its entire circumference continuously formed, in particular smooth upper side. The upper side is that side of the annular collar which is directed towards the light source in the assembled state of the luminaire. The continuous top allows a simple way to provide a pivot bearing.

Further advantageously, the annular collar on its underside in the axial direction projecting ribs. These allow interaction with a slider element or other suitable actuating element for preventing rotation of the receiving element relative to the mounting element.

Further advantageously, it is provided that the installation element has a window, in particular a slanted window slot. Like the previously mentioned annular collar, the window can also be provided in all different variants of a mounting element of one size. The window also provides a cross-variant interface of the mounting element for the receiving element. On the receiving element, a radially outwardly projecting control pin can be arranged, which engages in the assembled state in the window. The control pin can provide in cooperation with the window for a defined possible rotational movement of the receiving element relative to the mounting element by slightly more than 360 °, as well as for preventing the rotational movement in both directions of rotation about a z. B. 365 ° range addition.

Further advantageously, the annular mounting element is designed such that it provides an insertion opening for the receiving element. Through the insertion through the receiving element for the purpose of its definition is insertable. The insertion movement ends when the radially outwardly arranged on the receiving element annular collar with the radially inwardly projecting annular collar of the mounting element into abutment. Other stop surfaces for limiting an insertion movement in the axial direction may be provided.

Advantageously, the connecting means are designed such that upon a movement of the receiving element to the mounting element to a clip-like locking takes place a backup. As a result, on the one hand a tool-free attachment can be achieved. On the other hand, the user is acoustically indicated that a detent position has been reached.

As connecting means spring tabs can be provided, which are aligned in particular in the axial direction. These can in particular be designed in one piece-materially connected to the receiving element. These connecting means may be kept the same in different variants of the receiving element, so that here a defined interface is provided on the receiving element for the mounting element.

The spring tabs may have a holding surface which is slightly radially displaceable. Further, the spring tab may have an insertion bevel, which provides for a slight radially inwardly directed displacement of the spring tab end at a plugging of the receiving element, and allows the holding surface of the spring tab engages over the top of the inwardly standing annular collar on the mounting element.

Advantageously, it is provided that the annular collar of the receiving element and the annular collar of the mounting element radially overlap or overlap in the assembled state of receiving element and mounting element. Thus, a particularly simple implementation of a stop can be achieved during an insertion movement of the receiving element into the installation element.

The receiving element is advantageously rotatable relative to the mounting element when it is mounted on the mounting element. The rotation can extend over an angle of about 365 °, advantageously stops are provided in both directions of rotation. The rotational movement allows alignment of the receiving element and thus also the light head fixed thereto relative to the mounting element. Thus, for example, with respect to the longitudinal center axis of the Recessed non-rotationally symmetrical light distribution positioning of the light distribution can be achieved.

The rotational movement can be locked or released by a slider element. This is advantageously displaced in the axial direction and may have actuating surfaces that allow a tool-free, manual adjustment. The slider element may have two ends, wherein the one end can cooperate with arranged on the underside of the inwardly standing annular collar of the mounting element axial ribs and can prevent its rotational position by cooperating with these ribs. The other end of the slider element may have a coding surface which can be brought into engagement with a counter-coding surface on the reflector element. In this way, a reflector element providing a non-rotationally symmetrical light distribution can be converted into a proper rotational position.

On the receiving element struts are arranged, on which the headband are mounted. The struts are preferably integrally-materially fixed to the mounting element. The headband are preferably made of metal and screwed or riveted to the free ends of the struts.

A first variant of a receiving ring comprises retaining brackets which are rigidly arranged relative to the braces, and a second variant of a retaining ring comprises retaining brackets which are pivotably arranged relative to the braces.

All different variants of the receiving element allow use with the same mounting element and the same light head.

In the module construction system according to the invention, a light head is provided, which may consist of different variants. Different variants of the light head can be connected to one and the same receiving element. On the other hand, one and the same light head can be connected in different variants of the receiving element.

The light head may comprise a metallic housing part, on which in particular cooling fins are arranged. On the housing part, a top reflector is preferably attached. Finally, a light source and a socket or circuit board for the light source is fixed to the housing part. The determination of the upper reflector on the housing part can be done with the interposition of a sheet metal element. The sheet metal element is screwed to the housing part. Different top reflectors can be fixed to the same sheet metal element.

Another variant of a reflector element shows 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 modular building system for recessed luminaires according to the invention is that the different variants of the components of this system 10 almost any combination can be combined. 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 according to the invention 11 a particularly simple on-site installation 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.

The following is initially the installation element 12 be described in more detail:
evidenced 1 has the installation element 12a a substantially annular structure. The wall 24 forms an axially short tube section. On re 1 lower free end of the wall 24 is a radially outwardly projecting flange-like collar 23 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 installation element 12 includes according to 1 two spreading spring elements 22a . 22b That's what's best 4 can be seen, tangentially protrude. The two expansion spring elements 22a . 22b advantageously have a tooth structure on their respective underside 77 on.

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

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 lies in the installed state of the installation element 12a at the bottom of the ceiling wall.

It should be noted that during the insertion of the installation element 12a in the ceiling-side mounting opening the expansion springs are biased radially inwardly or manually pressed inward to a passing through the mounting element 12a to allow 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 with a toothing 77 provided underside 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 gearing 77 are designed so that to cover different wall thicknesses of the false ceiling the same installation element 12a can be used.

Alternatively to the spreading springs 22 provided fixing means of the variant according to 1 has the installation element 12b according to 2 Haltebleche 28a . 28b . 28c on. These perforated sheets with numerous openings 28a . 28b . 28c are through slots 80a . 80b . 80c . 80d in the wall 24 this installation element 12b been put through. The installation element 12b according to 2 has a cleaning edge 29 on, in particular in the sectional view according to 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 through. As a result, the radial distance of the sheet 28a adjusted to the cleaning edge, in adaptation to the construction site specification. The perforated sheets 28 are on the on the mounting element 12b kept captive.

Another variant of the component installation element shows 3 in the form of the annular mounting element 12c , Here are as fixing means brackets or blocks 30a . 30b . 30c provided, respectively, about a pivot axis 31 swiveling, on web-like extensions 81a . 81b . 81c are fixed. The extensions 81a . 81b . 81c carry on their outside a step arrangement 32 with a series of ratchet teeth.

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

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

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

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

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

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

Next is the different variants 12a . 12b . 12c the mounting element in common, that these matching dimensions of an inner diameter Di of the annular collar 25 exhibit, like this 7 is apparent.

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

Each of the three mounting elements has beyond a uniformly shaped slot 43 in the wall 24 whose function will be explained later.

A selection of the appropriate installation element 12 The expert will make depending on, for example, the desired ceiling, as well as depending on what type of completion - plastering or protruding collar - is desired.

Based on 8th will now be a first variant 13a an annular receiving element described.

8th 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 , In terms of 8th extend axially upward two strut-like projections 36a and 36b that attaching brackets 41 serve. Such headband 41a . 41b shows, for example, the unit of 14 and 15 , By means of an in 15 With 84 designated fastener, for example, a determination of a preferably consisting of metal retaining clip 41a . 41b at a mounting hole 85 a strut 36a . 36b respectively.

It should already be mentioned that, as the building unit of 14 and 15 shows a determination of the headband both in rigid connection to the receiving element 13a can take place, or alternatively, as in particular the 36 and 22 show, also a pivotal attachment of a retaining clip 41 at the strut 36 can be done, with the attachment opening 85 a pivot axis 42 for the corresponding headband and attached to the headband lighthead 15 formed.

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

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

The outer diameter Da of the receiving element 13 at its widest point, in the area of the outer sides of the outer collar 34 , is in the 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. 4 ).

In other words, an axial insertion movement of a receiving element 13 in a wall-mounted installation element 12 by hitting the top 38 of the Confederation 34 on the bottom 39 of the inner federation 25 limited. These geometric relationships, for example, shows the sectional view of 12 ,

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

As a result of the left open spaces 86a . 86b . 86c becomes a pivoting of the spring tabs 37a and 37b through the twistable bridge sections 87a and 87b achieved, which thus form the pivot axis.

As a result of an insertion movement of the receiving element 13a in a built-in element 12b gets the top 88 (see. 12 ) of the corresponding spring tab 37 in contact with a corresponding Eckwandungsbereich 89 the wall-mounted mounting element 12b so that the spring tabs 37 perform a radial inward movement, until the locking nose-like end 90 the respective spring tab 37 on the inner waistband 25 of the installation element 12b passed by and on top of it 26 rests.

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

Another insertion of the receiving element 13a in the wall-mounted installation element 12b is due to the radial coverage of outer collar 34 and inner waistband 25 prevented. At the time of striking the two leagues 34 . 25 is the locking nose end 19 on the inner waistband 25 vorbeipassiert.

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

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

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 the receiving element 13 from the wall-mounted installation element 12 to solve.

In an alternative variant, not shown, also a tool-free solution of the receiving element 13 from the wall-mounted installation element 12 respectively.

It is crucial that a dimensioning and design of the spring tabs 37 such that on the one hand an effortless insertion of the receiving element 13 in the installation element 12 possible and a 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 be held securely without the receiving element unintentionally from the mounting element 12 solves.

The connecting means described above for the detachable connection of a receiving element to a mounting element are based on the three pairs of spring tabs 37 in cooperation with the radially inwardly projecting annular collar 25 to understand the installation element only by way of example. 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 and more or less spring tabs, if they are designed to be suitable, can 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 installation element 12 Now, with reference to the embodiments of the 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 mounted 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 protruding ring collar 25 of the mounting element as a sliding bearing surface for the bottom or the locking nose 90 the spring tabs 37 acts.

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 above-described, on the mounting element 12 provided slot 43 provided with a control pin 47 on the receiving element 13 cooperates.

evidenced 23 is a control pin 47 one-piece cohesively fixed over a connection area 49 with the wall 35 of the receiving element 13 connected. As a result of free cuts 48 Axial mobility is achieved because there is a Biegeachsbereich 50 that forms a slight Pivoting the control pin 47 around the bending axis 50 allows.

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

A rotation limit in the first direction of rotation is achieved by an inward of the wall of the mounting element 12 above, in 24 only dashed lines indicated stop wall 91 , This acts in such a way with the control pin 47 together, that a further rotational movement of the receiving element relative to the mounting element in the sense of a relative movement of the receiving element relative to the 24 to the left, is prevented.

In the other sense of rotation, starting from the state of 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 meets the ramp 44 which are radially inward of the slot 47 is arranged and the the control pin 47 for leaving his trajectory BW forces. Finally, the control pin 47 , like this 25 shows - due to further rotation of the receiving element - along the ramp 44 be moved axially. That related to 25 right end 45 of the slot 43 makes 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 25 to the right. It should be noted that 25 not yet the stop position, but only an intermediate position, just before reaching the stop shows.

It should be further clarified that due to the fact that the two stop surfaces 91 respectively. 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 equally described a axial offset of the two stop positions of the control pin 47 allows. 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 14 to 18 first a handling unit 92 be explained, which is a receiving element 13a , Headband 41a . 41b and a lighthead 15 includes.

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

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

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 14 not shown, be made with the wall already laid electrical line.

The different embodiments of the 19 to 22 should illustrate that for the same, on the ceiling wall 93 fixed installation element 12 a variety of different handling units 92a . 92b . 92c . 92d is available, each optionally on the same mounting element 12 can be determined. The 19 to 22 also clarify that a specification of the handling unit 92 only takes place when the installation element 12 already set on the wall side.

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

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

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

Next, like this 22 shows, the lighthead 15d around the pivot axis 42 pivotable to the receiving element 13b be arranged to allow an individual alignment and positioning of the light head. 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 19 to 22 but also that different light heads 15a . 15b . 15c . 15d with the same receiving element 13a can interact. Consequently, different lights 11a . 11b . 11c . 11d . 11e from different variants of components of the modular construction system according to the invention 10 composed.

In the following, the interaction between a reflector element 14 and a receiving element 13 be explained:
The reflector element 14a For example, consists of pressed aluminum and has a wall 54 on, which is preferably mirror-polished on its inside. While the reflector element 14b according to 33 is formed substantially rotationally symmetrical, is in the reflector element 14a according to 28 a vertex portion cut off obliquely, so that in particular from the side view 29 resulting unbalanced training results.

The reflector element 14 has a border area 55 on, which is reached by beading. The reflector element is, as the particular 31 and 32 show, twice folded in the free edge area and finally rolled inwards.

The special feature here is that the reflector element 14 tool-free, while achieving a kind of snap ring, with the receiving element 13 can cooperate. The receiving element 13 has as variants cross-mechanical interface three 120 ° circumferentially offset arranged spring tabs 59a . 59b . 59c on the re 9 lower free edge area of the wall 35 are arranged. These three spring tabs 59a . 59b . 59c can in the interior 95 the beaded edge area 55 intervention. Here are the spring tabs 59a . 59b . 59c , as can be seen in particular from the sectional view of 34 results, with a holding nose 96 equipped by the free edge area 97 the beaded edge 57 can be underrun. 34 shows this situation only schematically.

The special feature is that the reflector element 14 only then on the receiving element 13 is fastened when the receiving element 13 on the installation element 12 already set. Thus, the reflector element can be mounted as a last element in a simple manner.

The arrangement of spring tabs 59 allows tool-free attachment and 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 34 results is the bottom 61 of the free edge 55 the reflector element is substantially flush with the bottom 60 of the retaining collar 23 of the installation element 12 in assembled condition. This achieves a flush arrangement. If instead of a mounting element with retaining collar 23 a built-in element 12 with cleaning edge 29 is used is the bottom 61 of the edge 55 of the reflector element 14 in the assembled state flush with the plaster edge 29 arranged. The concept of conciseness of this arrangement also includes, as this 34 indicates slight returns.

The 28 and 29 leave a recess 56 at the free edge 55 Detect the reflector element. The recess 56 can with the coding end 58 of the slide element 51 interact.

The 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 is the slide element 51 fixed axially displaceable. The slider element 51 is between the in 26 indicated axially lower and the in 27 indicated axially movable upper position. The slider 51 has two slider cams 52a . 52b on, the form-fitting in appropriate bays 53a . 53b at the bottom of the inner waistband 25 on the installation element 12 can intervene.

Is the slider element 51 in the in 26 shown lower position, is the receiving element 13 relative to the mounting element 12 freely rotatable. Will the slider 51 by manual attack on the actuating surfaces 98 from the position according to 26 in the position according to 27 proceed, grab the control cams 52a . 52b so in the interstices 52a . 53b the ribs 27a . 27b in 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 26 lower end 58 of the slide element 51 can with the Codierausnehmung 56 on the edge 55 of the reflector element 14 interact. Especially with such reflector elements 14 , which generate a non-rotationally symmetric light distribution, the reflector element 14 with its coding recess 56 such relative to the receiving element 13 be positioned that the coding end 58 of the slider 51 in the Codierausnehmung 56 intervenes.

With reference to the embodiment of 37 should first be made clear that to a recessed light 11 consisting of components of the modular system according to the invention 10 is composed, at least in some variants, a diffuser element 62 can belong. The diffuser element 62 is by holding means, not shown in detail on the reflector element 14 attached and forms together with this a handling unit.

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

With reference to the 38 and 39 is another element of the modular system according to the invention 10 presented: 39 shows in perspective in solo representation an adapter element, which serves, for example, a shadow gap 99 provide. 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 on, which are arranged circumferentially offset 120 °. Adjacent to the pairs of spring tabs is an annular, circumferential annular end face 100 provided, in terms of their geometric design of the top 36 of the outwardly projecting annular collar 34 of the receiving element corresponds.

Like the right half of the 38 indicates, the top works 100 of the axial section 101 of the adapter element 16 with the inwardly projecting annular collar 25 of the installation element 12a together.

The adapter element 16 points beyond - in analogy to the arrangement of a ring collar on the mounting element - an inwardly leaping collar 63 on. This has a top 26 on top of that 26 an inwardly leaping ring collar 25 a conventional installation element corresponds. In addition, at the bottom in the axial direction extending ribs 27a . 27b intended.

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

While the module system according to the invention 10 the individual components 12 . 13 . 14 each holds in different sizes in stock, the adapter element 16 ensure that a receiving element of a smaller size can cooperate with a built-in 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 38 and 39 the possibility of that adapter element 16 with a downwardly double-walled training with an axial section 101 and a second axial section 102 to provide a shadow gap between them 99 form. Such a design is desirable in certain applications.

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

As evidenced by the embodiment of 40 is a square, annular receiving element 17a shown. This includes - in analogy to the embodiment of an annular receiving element 13 - a pair of struts 36a . 36b , which are identical in terms of their geometry or similar designed the struts of an annular receiving element.

In particular, the struts 36a and 36b of the square receiving element 17a sized and spaced from each other so that the same headband and the same light heads can be attached both to a square receiving element, as well as on an annular receiving element.

The square receiving element 17a has two pairs of spring tabs on two opposite sides 37a . 37b on, which need not be explained in detail, since their function and mode of action 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 56 cooperate. On the square installation element 20a is again an inner circumferential arrangement of an inwardly projecting annular collar 25 intended. The spring tabs 37a . 37b come after insertion of the square receiving element in the already wall side fixed installation element 20a , at the top 26 of the inner federation 25 to the concern.

56 shows the square mounting element with a cleaning edge 29 , The alternative variant according to 57 shows an outwardly projecting collar. Also makes the sequence of 56 and 57 clearly that - in analogy to the annular configuration of a mounting element - again different variants of a mounting element may be provided for fixing to the false ceiling. Among other things, can be used as a fixing agent in turn perforated plates 28a . 28b or bracket 30a . 30b be provided.

At this point is also on the variants of 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. So can the installation element 73a according to 58a from two conventional built-in elements 20a according to 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, there is the possibility, both, now in a double installation element 73a Risen conventional built-in elements 20a . 20b each separately with recording elements 17a according to 41 to equip.

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

In a further, not shown variant of a double arrangement of a particular rectangular mounting element, similar to the mounting element 73a of the 58 , Can a production of such a rectangular mounting element of two square mounting elements 20a according to 56 respectively.

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

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

With reference to the 50 to 53 it becomes clear that both housing parts 19a and 19b each a pair of holes 28a . 28b having a same bore spacing BM. This will provide a mechanical interface for connection to the brackets 41 provided the receiving element. Since the bore distance BM is always the same, different housing parts can be used 19a . 19b always on the same receiving element 13 respectively. 17 be determined.

The holes 68a . 68b , as well as the other, later still to be explained 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 other mounting holes, namely the holes 69a . 69b . 69c . 69d . 69e . 69f . 69g on. The housing part 19b according to 51 a series of mounting holes 69a . 69c . 69g . 69h . 69i . 69j on.

It becomes clear that the two housing parts 19a and 19b Insofar also include identical mounting holes on the housing part 19a With 69a and 69b and the housing part 19b With 69a and 69c are designated. 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 a first pair of holes 69c . 69f and a second pair of holes 69d and 69e on, which can optionally be used to attach different lamp holders. 52 shows that the fixing holes 69c . 69f used to the socket part 70a set. At this version part is the bulb, ie the lamp 71a , attached.

Not shown is the further variant in which the mounting holes 69d . 69e be used to screw the socket for another, not shown bulbs.

In the embodiment of the housing part 19b according to 51 turn, a plurality of mounting holes is provided with the 69g . 69h . 69i and 69j are designated. These are two pairs of mounting holes, which can be used optionally for connecting different sockets for different light sources. 53 and 55 show the housing part 16b according to 51 on which a bulb 71b with an associated version 70b is screwed.
