Description

The invention relates to a recessed light, which is set up in a Installation opening to be installed. The recessed luminaire on which the Component having installation opening be attached. Such an embodiment is e.g. given a recessed luminaire set up for installation in a wall opening is. In the case of a recessed ceiling light, this can be both at the installation opening having ceiling or false ceiling can be attached or the recessed light can attached to a beam placed above the ceiling or false ceiling, e.g. by means of wires or ribbons.

From the publication DE 37 39 076 A1, a recessed luminaire is the one described above the first type can be seen in which the recessed light at each of the recessed opening having component is attached. In contrast, in DE 39 32 881 C2 Downlight described by a wire attached to one above the associated Suspended ceiling ceiling is attached.

There are several requirements for a recessed luminaire. For one, it is a typical mass product, the parts of which are simpler and cheaper Should be construction, so that the recessed luminaire is generally inexpensive. Therefore is also a material-saving construction and a low weight is sought, which makes transport and assembly easier. On the other hand, the installation of the Recessed luminaire in the opening with a considerable effort, because on the one hand, the recessed luminaire is fully assembled in the area of the installation opening and on the other hand, an installation opening is usually difficult to access, e.g. from one Ladder, so installation is difficult and time consuming. In addition, a Secure installation must be ensured so that the attachment is safe even after years is guaranteed.

Recessed luminaires in a variety of different designs have already been developed been. In US 2 939 669 is a suspension device for a built-in lamp described, consisting of a bridge-shaped support device on the underside a reflector is screwed on. The bridge device has a central support part, that extends across the reflector and at each end with a support leg is connected in the form of a support bracket, the free end of which for support a ceiling containing the installation opening is set up. The support part and the Support legs are through an adjustment device transverse to the elongated installation opening adjustable and lockable in the respective adjustment position. Holding means for holding at least one lamp and for the power supply of the same are in this Documentation not described.

In US 3,388,247 there is a recessed luminaire in the form of an elongated tube luminaire described, the two end cap-shaped base parts with short top Has elbows, each of which is penetrated by a vertical screw, the head on the underside has a tool engagement element for turning. The screws are located near the adjacent edges of the installation opening. Besides, is a reflector is provided. On each screw there is a clamping part with an edge the opening protruding arm. By turning the reflector in one Leave the screws passing through the hole using a rotating element attached from below the tensioning parts pull against the ceiling. Apparently the reflector is exclusive held by the lower heads of the screws. Further fastening measures for the reflector are not described.

A recessed ceiling light can be found in EP 0 499 044 A1 Holding means in the form of a pot-shaped base part inserted into the installation opening, a circular cylindrical hollow body inserted into the base part with a Diffuser in its lower area and a halogen reflector lamp in the hollow body having. There are mounting devices for holding the recessed light in the installation opening provided consisting of retaining springs each having two legs, from which one leg rests on the edge of the hole and the other leg on the ceiling lies on. In this known embodiment, the holding means must be designed so that they snap into their fastening position automatically when the base part is inserted and therefore have to fit exactly. Manual manipulation of the holding means from the interior of the base part is not possible because the base part is pot-shaped closed is. It is also difficult to access the halogen reflector lamp presumably first loosened the attachment of the hollow body and the hollow body after must be removed below to gain access to the halogen reflector lamp to clear.

In US 4,238,815 a recessed luminaire is described in which the light influencing means in Shape of a reflector can be suspended by means of chains in an assembly position. Besides, they are Light influencing means in its working position by means of catches arranged on both sides releasably held, which are connected to the mounting means with which the recessed light on one Ceiling is supported.

A recessed luminaire of the type specified at the outset is described in US Pat. No. 3,035,165. At this Known recessed luminaires are two-part light influencing means, namely an upper one Light influencing part and a lower light influencing part in the form of reflectors described. The upper light influencing middle part is with its side edge at an edge part of the Recessed light articulated. The lower light influencing part is through on both sides Existing connection devices can be detached with the mounting means of the recessed light connected. The connecting devices have a peculiarity in that they have a Intermediate bracket of the lower light influencing middle part in a slightly recessed position not allow accessibility to the lamp is guaranteed. Access to the lamp is only possible when the lower one Light influencing part is completely disassembled.

The invention is based, so a recessed light of the generic type the task design that simplifies their installation or final assembly and / or their accessibility is improved.

This object is solved by the features of claim 1.

The invention is not only suitable for a recessed luminaire 1 with a rectangular cross section as described above and shown in Fig. 6, but for all possible Cross-sectional shapes, especially for a square and round one Cross-sectional shape, as shown in FIGS. 7 and 8 each in the bottom view. At a Round or rounded shape, the edge part 8 in one piece in the circumferential direction be trained. Especially with a round or square cross-sectional shape Recessed luminaire 1 and corresponding width of the edge part 8, the installation opening 6 have a substantially round or square cross-sectional shape (Fig. 8).

9, there are several, here three Recessed lights 1 according to the invention directly in the longitudinal direction assembled one behind the other to form a light band 65. The two Recessed lights la, which form the ends of the light band 65 and the middle or possibly Several medium-sized recessed lights 1b can in the sense of the above-described designs be formed, but they differ in the design of the edge part 8 in the region of the transverse vertical butt joints 66 on which they are put together. All three recessed lights are missing in the area of the butt joints 66 la, 1b of the transverse section 8b or 8d of the edge part 8. Instead point the longitudinal edge parts 8a, 8c one in the butt joint 66 and thus transversely running end surface on which they are put together and the associated Form butt joint 66. Thus, the middle recessed luminaire 1b has no cross at all extending frame section 8b, 8d, while the end recessed lights la have transverse edge sections 8b, 8d at their free ends. The Length of the recessed lights la, 1b is the so-called Cassette ceiling composed of individual ceiling tiles of the same dimensions Adjusted ceiling 7. As a result, the end transverse edge parts protrude 8b, 8d the associated division joint T of the cassette ceiling.

The width f and in particular the length g of an installation opening 6 is then in particular easy and inexpensive to implement in a blanket 7 if the width f and in particular the length g corresponds to the existing grid dimensions R, r, so that the Installation opening is not made in the ceiling 7 in a special way, e.g. milled in must, but the installation opening 6 by omitting a narrow Ceiling plate P can be formed.

In practice, the latitude and longitude of the Recessed luminaire 1, however, has the following special features. First, have in practice different grid dimensions R, r naturalized, which can have different causes, e.g. different manufacturers and / or different grid dimensions for the purpose of better Distribution of the ceiling area. There are e.g. Pitch R of 1200 mm and 1250 mm, see FIGS. 10 and 12. On the other hand, at one and the same width f Installation opening 6 different installation widths available for recessed luminaire 1, depending on whether a suspension device 23 (Fig. 1, left) or one Holding device 21 (Fig. 1, right) is used to hold the downlight 1. As clearly shown in FIG. 1, the vertical support leg of the support part 24 in FIG. 1 right less space than the combination suspension device 23 with the T-shaped Suspension part 34 and the associated support leg 24.

The adjusting screw 84 is with the light distributor 3 or Reflector 4 from below for the purpose of height or level adjustment or alignment accessible.

Instead of the previously described clamping parts 26 which are automatically fixed to the support leg 17, the holding devices 21 are holding parts 91 each with a laterally projecting holding leg 91a for gripping over the False ceiling 7a or parts of the suspension device 23, e.g. to the Grip over the rail-shaped suspension part 34 assigned, so that here too a holder between the abutment leg 25b and the holding leg 91a takes place, these parts can also have a clamping effect between them. The holding part 21 is vertically displaceable on the support leg in a sliding guide 27 24b stored and lockable in the respective shift position. For this, the Holding part 91 an upward or downward extending mounting leg 91b, which like the abutment 25 in the form of an angle by means of a Fixing screw 33 is releasably attached to the support leg 24b, the Attachment leg 91b in a hole and the support leg 24b in the slot 28 grasped.

In all the configurations described above, the holding devices 21 are due the flat or plate-shaped configuration of the base parts 2 after removal of the light distributor 3 from the space between the holding devices 21 Luminaire 1 forth easy to use, so that assembly or disassembly or a level adjustment of the lamp 1 is carried out in a manner that is easy to handle can be.

Within the scope of the invention, it is possible with all of the above-described configurations the light distributor 3 not on the base part 2 but on the holding devices 21, on the lower ends of the support legs 24b or at the abutment legs 25b fasten. Quick-connect connections, e.g. a Locking device, serve to a quick and easy to use Assemble or disassemble the light guide 3 to achieve.

Instead of one directly between the base part 2 and the light distributor 3 effective locking device can be the same or different Quick-connect connection 58 between the light distributor 3 and the holding devices 21 or the holding means 5 may be provided. 18 in the embodiment in the free end regions of the support legs 24b holding elements for the light distributor 3, in particular for its edge part 8, arranged. The holding element can on the associated abutment leg 25b be held. It can also be between one Holding position and a release position can be arranged movably in a guide 90 and preferably be urged into its holding position by a spring force. 18 are hook-shaped or claw-shaped holding parts 92 on the associated Abutment leg 25b between an inner holding position in which a holding claw 92a engages over and under the edge part 8 from the outside, and an outer release position, in which the holding claw 92a releases the edge part 8 and the light distributor 3 with its opposite edge parts 8 can be placed from below between the holding claws 92a, slidably mounted and in the holding position by a locking device lockable or held by a spring force.

The downlight 1 shown in Fig. 18, in the same or comparable parts are provided with the same reference numbers, differs from those described above Refinements in several ways.

On the one hand, the base part 2 is of a different design, and it is not directly with the Support legs or brackets 24 connected but indirectly by two or a plurality of longitudinally spaced support parts 101 with which the Support legs or support bracket 24 are detachably connected, preferably by a Quick-connect connection or latching device 102. Each support part 101 forms with two support legs 24 arranged on both sides a bridge-shaped Holding device 103 on which the base part 2 is connected by a connecting device 104 is detachably or hingedly connected. The releasable connector 104 is preferably by a quick-connect connection or latching device 105 formed, the latter with an expandable and collapsible arrangement of the base part 2 by a preferably detachable joint 106 with the holding device 103, here the Support part 101 is connected, which is located on a longitudinal side of the base part 2, wherein the locking device 105 is arranged on the other side. This is it is possible to open the base part 2 with the light distributor 3 removed, the electrical connection elements and operating devices 9 for electrical power supply, which are arranged on the base part 2, in a user-friendly working position in which e.g. the electrical connection cable is easy to use and quick can be connected to the connection elements. Then the base part 2 pivoted back into its pivoted assembly position and easy to use and quickly connected.

Another design difference relates to the quick-connect connection or latching device 58, with which the light distributor 3 is easy to use and can be installed quickly. In the present embodiment, on both sides of the Reflector 4 locking springs 107 are provided with locking lugs 108, each snap resiliently behind an associated locking projection on the base part 2, especially in the area of bent or angled legs 109 of the Base part 2.

In addition, to cover the open ridge area of the reflector 4 additional reflector part 111 is provided, which by a quick-connect or Plug connection or locking device 112 easy to use and fast at the bottom of the base part 2 can be connected to it. In the present Embodiment are in each case mutually opposite holding tongues 113 cut out of the base part 2 and bent obliquely downwards, behind the surrounds the reflector part 111 with lateral edge parts 111a. The connection of the Reflector part 111 can be done by manually compressing it, so that the edge parts 111a can be inserted between the holding tongues 113 and behind due to the inherent elasticity of the reflector part 111 can be elastically spread or that Reflector part 111 inserted in the longitudinal direction between the holding tongues 113 becomes.

The individual parts of the aforementioned exemplary embodiments are described in more detail below described.

As FIG. 19 clearly shows, the base part 2 is preferably straight extending base web 114 and the base legs 109 in cross section U-shaped, whereby in the end regions of the base legs 109 semicircularly curved longitudinal beads 115 are integrally formed, the locking projections, behind which the Can latch latches 108 elastically.

In each of the end regions of a base leg 109 there is a plug-in recess 116 arranged special shape that is part of the joint 106. The plug-in recess 116 extends only part of the length of the base leg 109, being in one Distance h from the base web 114 begins to go down through the longitudinal bead 115 extends and at a small distance i from the free, approximately parallel to the base web 114 extending edge of the base leg 109 ends. In the upper area the Plug-in recess 116 on one or both sides of a plug extension 117, the Function is described below.

Bent end walls 118 are provided on the front ends of the base part 2 partially limit the cavity of the base part 2 at the end.

The base part 2 is in one piece as a stamped / bent part from a plan view in FIG. 21 shown circuit board made of sheet steel.

The support part 101 consists of a U-shaped first connecting part 101a Connecting the support legs 24 and a second connecting part 101b for connecting of the base part 2. The support part 1 is with a web part 119 and its longitudinal edges bent legs 121 shaped U-shaped in cross-section, it being for a is arranged transversely to the base part 2 extending arrangement. In the end areas of the Leg 121 is the locking device 102 for releasably connecting the associated support leg 24 arranged. The part of the support part 101 belonging to Locking device 102 is through a plug-in recess 122 in one leg 121 and formed by a latching tongue 123 in the other leg 121. The Locking tongue 123 is through a cut 124 from the associated leg 121 cut out and bent obliquely inwards (see Fig. 23), whereby they extends obliquely down to the vicinity of the web part 119. The free end of the Latch tabs 123 may be tapered onto a latch pin 125 as is 22 shows. The two latching devices 102 are arranged reversed, so that in each leg 121 a plug-in recess 122 and a latching tongue 123 are arranged.

The second connecting part 101b is formed by two connecting legs 126, 127 formed, which extends from the web part 119 to the side facing away from the legs 121, here downward, and are preferably bent in one piece, the distance between the connecting legs 126, 127 is dimensioned so large that the base part 2 can be used in between. In the present embodiment, both are in the foot area Connecting leg 126, 127 a rectangular step bend 128 is provided, the arrangement is such that the base part 2 with little movement fits between the innermost step sections 129.

There are two support parts 101 with associated mounting means 5, the Distance from one another at the center distance j of the plug-in recesses 116 in the base part 2 is adjusted. At the ends of the connecting legs 126 are one or both sides Approach parts 131 arranged. The width dimensions of the connecting legs 126 and the attachment parts 131 are thus of the width dimensions of the plug-in recess 116 adapted that the extension parts 131 can be inserted into the plug extensions 117 and in the event of a displacement to the end region of the plug-in recess 116, engage behind it. in the The middle lower area of the attachment part 101 is a cutout 130 for electrical Components or cables provided.

A hole 132 is arranged in the free end region of the connecting leg 127. In addition, a plug-in recess can be made in the end edge of the connecting leg 127 133 may be provided. As can be seen from FIG. 25, each support part 101 is also one Stamped / bent part that is stamped and bent in one piece from a sheet metal sheet.

In the area of the horizontal support leg 24a is on one side projecting plug pin 137 and on the other side a plug recess 138 arranged, which are parts of the locking device 102. The plug pin 137 is with some play in the plug-in recess 122, the horizontal Support leg 24a rests on the web part 119. In this position the Plug-in recess 138 of the latching tongue 123 or the latching pin 125 see above assigned that the latter snaps into the recess 138. This is the Support leg 24a easy to handle, stable and securely detachable on the support member 101 attachable. The plug pin 137 and the plug recess 138 are preferably in the Area of a reduced with respect to the vertical shaft of the support leg 24 Width k tapers, with which it can move between legs 121 with little movement of the support member 101 fits. As a result, two are possibly offset in the longitudinal direction arranged step surfaces 139 created, which abut the end face of the support member 101 can and thereby both facilitate handling when plugging together as also improve stability. At the foot of the support leg 24 is the Abutment leg 25b bent horizontally, preferably in the area of one Constriction in the form of two opposing grooves 141 that it enable the side edge portions 142 extending up to these grooves 141 slightly angled, resulting in an approximately spherical support surface for the body 7 is formed.

The sliding guide 27 has a longitudinal slot 135 in the support leg 24 which extends from the Foot region of the vertical support leg 24b into the arch or the bend 29 extends and in the presence of a vertical support leg 24e between the Bow 29 and support leg 24a can extend into the support leg 24e. The vertical support leg 24e is present when the arch 29 supports 101 should protrude. At the end of the longitudinal slot 135 facing the support leg foot preferably a narrow slot 142 connects in the middle, which fits into a Slot extension 143 opens. The latter is on the curved part and in the assembled State in the section of the support leg 24 protruding from the supporting part 101 or in horizontal section or step bend 134 arranged.

In the design of the clamping part 26 and its clamping connection KV according to the 18 and 29 to 31, the clamping member 26 by a lower and upper Clamping legs 26a, 26b are formed which have an open angle wl of enclose about 45 °, the apex preferably being rounded. In the field of Curvature or the end region thereof are located in the clamping legs 26a, 26b two sides of two guide grooves 144, 145 one above the other, of which the top through lateral recesses are formed and the lower by initially to the outside pointing tongues 146 forming angular cutouts 147. The tongues 146 are preferably rounded downwards, creating a sharp recess edge is avoided and instead a rounded contact surface 148 is created. By doing A narrow slot extends in the free end region of the upper clamping leg 26b 149, which opens into a preferably rounded slot extension 151. In the area an elongated cutout 152 of the lower clamping leg 26a is arranged from the inward end of a narrow slot 153 goes out into a preferably rounded slot extension 154 opens. The arrangement is so that the slot extensions 151, 154 are approximately vertically one above the other. For Stabilizing the clamping leg 26a, it is advantageous to use lateral to provide bent reinforcement legs 155. In the free end area is the Clamping legs 26a bent downward in an approximately Z-shaped manner, with its support section 156 tapered and can have laterally slightly upwardly curved edge strips 156a. The free end of the upper clamping leg 26b is preferably rounded or wedge-shaped. According to FIG. 31, the clamping part 26 is preferably in one piece manufactured stamped / bent part e.g. made of steel or spring steel.

The sliding guide 27 is in the present embodiment by the Longitudinal slot 135 and the edge strips 156 of the support leg 24b delimiting it educated. For this purpose, the distance m between the guide grooves 144, 145 is one small movement clearance dimensioned smaller than the width n of the longitudinal slot 135, see above that the transverse edges of the guide grooves 144, 145 with the edge strips 156 Reach behind the play of movement. 18 and 29 show the clamping part 26 in its Clamping position in which it rests on the installation body 7 and with the support leg 24b is jammed. The jamming takes place through the contact of the outer transverse edges 157 of the upper guide grooves 145 on the outer sides of the edge strips 156 and Contact surfaces 148 on the inner sides of the edge strips 156. Because of the relative large length ratio of the effective distance o between the transverse edges 157 and associated contact surfaces 148 and the length P of the clamping leg 26a results automatically a jam in the sliding guide 27 when the clamping part 26 after is shifted upwards, even if the clamping leg 26a bends upwards entry. The clamping effect is still an edge effect of the transverse edges 157 reinforced. In contrast, the clamping part 26 can be moved relatively easily if the point of engagement for its displacement is in the vicinity of the guide grooves 144, 145 see distance q. When the clamping part 26 moves against the installation body 7 is, the clamping connection KV in the sliding guide 27 results automatically due to the clamping or bending stress occurring on the clamping leg 26a is illustrated by the upward arrow 158.

The displacement can be done manually or by means of a displacement device. in the In the first case, this can be handled easily in the area between the Base part 2 and the installation body 7 take place. In the second case they are Slot extensions 151, 154 are preferably provided, to which reference should also be made is taken.

The quick connect connection or locking device 105 is by a Latching lug 161 and a latching edge gripped by the latter, which interlock elastically and are therefore detachable. In the present The latching lug 161 is part of a latching spring 162, the one Latching projection 163 engages behind elastically. The locking spring 162 is attached to the holding device 103, preferably by an extension of the Connection leg 127 formed and in particular as a separate component thereon attached, e.g. by means of a screw or rivet which extends through the holes 132 and 132a screwed or riveted. The latching lug 161 is in one piece with the latching spring 162 formed by bending, the locking lug 161 on the underside Has bevel 164, which an automatic bending and snapping the Locking lug 161 behind the locking projection 163 when closing the Locking device 105 guaranteed. The latch spring 162 is preferred made from flat spring steel. About turning in the screw or rivet connection To prevent the locking spring 162 has a small at its foot end Bend 165 on, in a recess of the component supporting it, here in a Recesses recess 165a on the connecting leg 127. Preferably the shaft 160 of the locking spring 162 in its foot area in the form of an upside down U shaped, which increases the length and improves their elasticity becomes. The free end region of the locking spring 162 is in the locked position from the side of the existing reflector 4, so that it is easy to use tangible attack element 166 for bending and opening the Locking device 105 can serve. It is a medium or two in the End areas of the downlight 1 arranged quick-closing or Locking devices 105 are provided.

A quick release or latching device of the construction described above and Function can also be provided for the latching device 58. In the In the present embodiment, the latching device 58 is also due to the Locking spring 107 formed with the locking lug 108 integrally molded thereon, which can be attached to the holding device 103 or preferably to the reflector 4. The latch spring 107 is preferably S-shaped, with its upper belly forms the locking lug 108. The latching spring 107 is in its foot region 172 attached to the outside of the reflector 4, e.g. screwed or riveted what is hinted at.

The locking lug 108 is shaped in the form of an oblique contact surface 174, which is a automatic bending and snapping behind the associated, the Latch projection 163 forming longitudinal bead 115 guaranteed. Preferably the locking lug 107 also on its side opposite the contact surface 174 shaped in the form of an oblique contact surface 175, so that an automatic release by the exercise of a tensile force on the locking device 112 is ensured. In In this case, the biasing force of the locking spring 171 is so large that a solution due to the weight of the reflector 4 is prevented and only at Exercise of a certain manual traction takes place. Within the scope of the invention it is possible to pair each other in the central area of the recessed luminaire 1 To provide locking devices 58 arranged in mirror image on both sides or to provide two such pairs in the end regions of the recessed luminaire 1.

34, in which the same or comparable parts with the same Reference characters are provided, differs from that according to FIG. 18 in two ways Terms. On the one hand, the abutment parts 25 or abutment legs 25b reach under associated suspension webs 34b of a suspension device 23, the Suspension webs 34b with their outside legs the false ceiling 7a reach under, preferably in a recess 176 on the underside.

Both in the configuration according to FIG. 18 and in the configuration according to FIG. 34 Arrangement made so that across the vertical support legs 24b or associated support leg sections of the step bends 134 the associated Approximately correspond to the transverse dimension of the installation opening 8 or the suspension webs 34b, whereby a lateral positioning of the recessed light 1 is guaranteed.

Another difference from the embodiment according to FIG. 18 is that between a distance is provided between the ends of the supporting part 101 and the curves 29, which increases the sliding guide path and reduces the height of the support legs can be.

It is also advantageous in the present embodiment, the holding device 103 so that the distance between the support legs 24 is adjustable and thus the recessed light 1 can be fitted to installation openings 8 of different widths. For this purpose, different support legs 24 with horizontal lengths of different lengths can be used Support legs 24a or support parts 101 of different lengths can be provided, the Differences in length of existing increments in the width of the installation opening 8 are adjusted. Within the scope of the invention it is also possible to use several Locking device parts of the locking device 102 on the support part 101 or on to provide the horizontal support legs 24a, the distance between several existing locking device parts on the increment of differently wide installation openings 8 is adapted.

35, which shows only one side half of the recessed light 1, the clamping part 26 is a mechanical adjusting device 181, in particular for its Assigned displacement in the clamping position. The adjustment device 181 is through a pulling device is formed with a pulling rope 182, which on the clamping element in the Near the sliding guide 27 attacks and from the free interior 183 in front of the Installation body 7 is accessible here, e.g. in that the pull rope 182 e.g. at dismantled light distributor 3 or reflector 4 hangs down into the interior 183. For such a cable drive, the slot extensions 143, 151, 154 in the Support legs 24 and the clamping parts 26 are provided. 35 clearly shows the pull rope 182 extends on the outside of the associated support leg 24, here of its vertical support leg 24b. The pull rope 182 preferably does not engage lower clamping leg 26a but on the upper clamping leg 26b, it being the interspersed lower clamping leg in a through hole with movement, preferably with a protective sleeve 184 attached to the pull rope 182, which the The pull rope protects against damage to the edge of the hole. At the upper free end of the pull rope 182, a preferably round head 185 is attached, which the upper clamping leg 26b overlaps, here the slot extension 151 A the manual attack on the pull rope 182 corrective head 186 may also be located at the lower end of the pull rope. At the manually pulling up the associated clamping part 26 becomes the pull rope 182 automatically drawn. The attack of the pull cable 182 on the upper clamping leg 26b is advantageous because the tensile force acting on the latter means lifting the transverse edges 157 of the support leg 24b and therefore causes easier displacement. Such Adjustment device 181 is assigned to each support leg 24. By a manual pull on the pull cable 182 with the light distributor 3 not yet installed, the clamping part 26 from its pre-assembled standby position against the associated ceiling part 7 or 34b pull, jamming automatically with the support leg.

A suspension or suspension device 191 is for the light distributor 3 or the Reflector 4 is provided, which has at least one rope or the like. With his one end is fixed in the area of the installation opening 8, e.g. on part of the Suspension device 23 or on a support leg 24, the light distributor 3 with a hanger 192 is attached or attachable to the rope so that it in dismantled position can be suspended. The dimension s of the suspension is below Determine consideration of handling-friendly conditions. Preferably the suspension dimension s is to be chosen so large that the suspended light distributor 3 is light can be swung out to the side to access the recessed light 1 even further to improve. It is also advantageous to dimension the suspension dimension s so large that that the suspended light distributor 3 is below the folded-down base part 2 located. It is also advantageous to have the suspension device, here a rope, on the side staggered in the area of the recessed luminaire 1, i.e. the upper end of the rope laterally offset on parts of the recessed light, in particular a support leg attach and the lower end of the rope also on the side of the light distributor 3 fasten. With such a configuration, the suspension device 191 is at the same time a folding or swiveling device integrated because of the side Arrangement of the suspended light distributor 3 folds down or tilts. With elongated Luminaires, as is the case with fluorescent lamps with tubes, it is advantageous to use two a longitudinal distance from each other or in the end regions of the Recessed lamp 1 provided suspension devices 191, which are preferably are equally trained.

It is also an advantage to laterally offset the hanger 191 to be arranged on the side on which the laterally offset joint 106 is located.

In the present embodiment, the suspension device 191 is in the mechanical Slider 181 integrated, i.e. the rope 182 of the adjustment device 181 serves for hanging the light distributor 3, so that an additional hanging element is not is required. In this case it is advantageous to use a further attack element, e.g. in Shape of a particularly spherical head 186, at a distance from Arrange attack element 186 on the rope 182.

When arranging a suspension device 191, it is important that Attach suspension element in such a position on the light guide that the Suspension element or rope 182 in the fully assembled position of the recessed luminaire 1 is not visible. The suspension device 191 and / or the are therefore suitable Adjusting device 181 is very good for the present exemplary embodiment, in which the Light distributor 3 an edge part 8 covering the installation opening 8 over the entire Scope or in particular with elongated recessed lights 1 only on the two Has long sides.

35, 36 and 37 show, the hanging device 192 is on the associated Rear of the reflector 4 arranged. It is through an insertion hole 193 and one of this outgoing insertion slot 194 preferably in the area close to the reflector the locking spring 107 formed. The insertion hole 193 is dimensioned somewhat larger than the head 185 on the rope 182, the insertion slot 194 being dimensioned somewhat wider than the cross section of the rope 182 so that the head 185 behind the insertion slot 194 hooks. The arrangement should preferably be such that in the suspended 38 the cable 182 to the closed end of the insertion slot 194 is pulled due to the weight of the light distributor 3 and thus a automatic unhooking of this connection is prevented. In the present Embodiment, the insertion slot 194 extends from the insertion hole 193 in the direction on the free end of the locking spring.

Process steps for mounting the recessed luminaire 1 are described below using the 36 to 39 are described.

For pre-assembly of the recessed luminaire 1, the base part 2 with the associated, preferably arranged on its back electrical components 9 and Support parts 101 by plugging together in the joints 106 and closing the Connection device 104, 105 pre-assembled and then with the associated Support legs 24 and the light distributor 3 as separate, not pre-assembled components Installation site supplied, the support legs 24 with the associated clamping part 26 in the release position and preferably with the adjusting device 181 a structural unit form. To this extent, the downlight 1 includes only three types of components that are on the Installation opening are to be installed, namely through the base part 2 and the support parts 101 unit B1 formed, four support leg units B2 and also one Unit B3 forming light distributor 3.

The attachment of the support legs 24 to the support members 101 can at the construction site or in the Installation opening 8 can be handled easily and quickly by plugging together, which clarifies Fig. 36.

A unit B4 which has been further complemented so far according to FIG. 37 can easy to handle inserted into the installation opening 8, the Clamping parts 26 were previously pushed into the non-distracting installation position in which they are shifted inwards if they are not already in this standby position are located. Then all you need to do is pull down and tighten the Clamping parts 26 against the installation body 7, here the false ceiling 7a, the Clamp the clamping parts 26 automatically on the support legs 24.

A further assembly step according to FIG. 38 is to fold down the base part 2, so that the electrical connection elements q arranged on the rear thereof in a Manageable accessible position to get the electrical connection to execute. Then the base part 2 is pivoted up into its end position, whereby it automatically locked. Subsequently, the insertion of the lamp 11, here a tube, and the light distributor 3 is inserted and connected into the recessed luminaire 1. So that is assembly finished.

It is advantageous to connect the light distributor 3 to the cable 182 of the suspension device 191 or the displacement device 181 before insertion, as shown in FIG. 38, and then to insert it into the recessed light 1 and connect it, the cable 182 at least 35 can form a loop 195 according to FIG. 35 or can rest on the edge part 8. If the light distributor 3 is mounted in this way, opening it later, for example for the purpose of replacing a lamp 11, is considerably simplified because the light distributor 3 can be suspended in a simple manner and therefore this work can be carried out in a more user-friendly, simple and better manner. In the suspension device 191 arranged opposite each other, the cable 181 is not connected to the reflector 4. The free end of the rope can lie on the reflector, here on the edge part 8.
The adjustment devices 181 assigned to each support leg 24 or four support legs 24 in the present exemplary embodiment can also be provided separately from one or, in the case of an elongated recessed light 1, preferably two suspension devices 191, which are preferably arranged in the region of the support legs 24.
