In this case, a veneer is provided at the light exit opening of the lamp body, which projects beyond the outer edge of the lamp body, so that the ceiling opening is hidden, and also forms an axial stop for the lamp during installation.
  • the fixation of the known recessed lights on the ceiling is usually done by a plurality of double torsion springs, which are mounted along the circumference of the lamp body and in the assembled state of Recessed light in the ceiling in which they are mounted, engage behind under elastic deformation and pull the veneer against the ceiling front.
  • the well-known recessed luminaire has proven itself in practice. However, it is still expensive to replace a light unit with a light unit of another type having different dimensions.
  • Object of the present invention is to provide a recessed luminaire of the aforementioned type so that it can be easily converted.
  • a support frame is fixed to the mounting ring, which defines a mounting space for the light unit and has at its front facing away from the mounting ring top fastening means to fix the light unit to the support frame.
  • the invention is therefore based on the consideration not to fix the light unit to the mounting ring directly, but via a support frame, which defines a mounting space for the light unit and receives them.
  • the mounting space is of such a size that it can accommodate all the different types of lighting units to be used with the recessed luminaire. Since, according to the invention, the light units are provided by means of the fastening means provided on the upper side of the support frame - i. From above - are mounted on the support frame, it is easily possible to mount light units of different types in the support frame.
  • the support frame has a plurality of struts, in particular distributed uniformly over the circumference of the mounting ring, which struts in particular at its lower region are connected to the mounting ring and carry at its upper region, the fasteners.
  • This open design of the support frame has the advantage that parts of the light units mounted therein can pass between the struts and therefore the design of the light units are not or only slightly affected by the dimensions of the support frame. Furthermore, the developing heat can be easily dissipated.
  • the struts are connected in their upper end region by a flat cover plate of the support frame, on which the fastening means are provided.
  • the cover plate may have a central heat dissipation opening to improve the heat dissipation, wherein it is then suitably annular in adaptation to the shape of the mounting ring.
  • the fastening means are formed according to an embodiment of the invention as bores, via which the light unit can be screwed to the support frame.
  • the support frame has at its lower end region facing the mounting ring a base ring which connects the lower ends of the struts with each other.
  • the support frame forms a compact and stable unit.
  • the mounting of the support frame on the mounting ring can be made via the base ring. This assembly can be done directly.
  • the support frame is fixed to the mounting ring via an intermediate ring which is detachably connected in the mounting ring from its underside and releasably connected to the mounting ring.
  • the detachable connection can be made in particular via a clamping or locking mechanism.
  • this embodiment has the advantage that the intermediate ring can be rotated about the longitudinal axis of the recessed light relative to the mounting ring.
  • the light unit should be pivotable relative to the mounting ring.
  • the support frame is pivotally attached to the mounting ring via bearing bolts.
  • the support frame is pivotally mounted on the intermediate ring via bearing bolts, so that no special precautions must be taken to fix the intermediate ring on the mounting ring.
  • the support frame preferably has sleeves, which are penetrated by the bearing bolts.
  • the recessed light may further comprise a filter retaining ring which is inserted into the mounting ring or in the intermediate ring and can be releasably fixed to the support frame by means of a clamping mechanism.
  • the arrangement can be made so that the filter retaining ring can be moved pivotally relative to the sleeves.
  • the holding force of the clamping mechanism via which the intermediate ring and the mounting ring are interconnected, is stronger than the clamping mechanism, via which the filter retaining ring is fixed to the intermediate ring, so that upon release of the filter retaining ring not also the connection of the light unit is separated from the mounting ring.
  • a spacer may be provided which defines a minimum required clearance above the support frame.
  • the support frame consists of a heat-storing material such as aluminum.
  • the support frame can absorb heat generated by the light unit in operation.
  • FIGS. 1 and 2 a first embodiment of a recessed luminaire 1 according to the present invention is shown, which can be installed in an opening of a suspended ceiling, a thin wall o. The like. Not shown.
  • the recessed luminaire 1 has a luminaire body which can be inserted into the ceiling opening and is formed by a light unit 3 containing the lighting technology and a mounting ring 4.
  • the mounting ring 4 has a cylindrical basic shape with an outer diameter which is chosen so that it can be inserted into a corresponding round ceiling opening.
  • the mounting ring 4 defines on its underside a light exit opening, around which the mounting ring 4 carries a flange-like outwardly facing facing 5.
  • two elastic retaining elements 6 are provided on the mounting ring 4, which are positioned diametrically opposite one another and in each case a stop plate 7 and a leaf spring-like tongue element 8 attached thereto have, wherein the tongue elements 8 in the assembled state, the wall or ceiling, in which the recessed light is installed 1, engage behind and pull the veneer 5 against the ceiling front.
  • the recessed luminaire 1 is round.
  • the recessed light with light unit 3 and mounting ring 4 also have a rectangular, square or oval shape.
  • the light unit 3 comprises a reflector 9 - here a reflector 9, which generates a so-called Batwing light distribution - which is open at its underside and a lamp holder 10 for an unillustrated horizontal illuminant, which is positioned in the upper region of the reflector 9, wearing.
  • the reflector 9 and the lamp holder 10 are fixed to a holder 11, which is arranged above the reflector 9.
  • the light unit 3 includes a supply plug 12 for connection to an electrical supply unit.
  • the light unit 3 thus formed is provided in a mounting space of a support frame 13 which surrounds the light unit 3.
  • the support frame 13 which consists of a heat-storing material such as aluminum and is designed here as an aluminum die-cast part, is supported by a lower, the reflector 9 in the region surrounding its light exit opening base ring 14, an upper, also annularly shaped cover plate 15 and four extending between the base ring 14 and the upper cover plate 15, approximately offset by 90 ° from each other arranged struts 16 formed.
  • the light unit 3 is mounted on the provided at the top of the reflector 9 holder 11. Specifically, two mutually corresponding mounting holes 17, 18 are formed in the cover plate 15 of the support frame 13 and the holder 11 of the light unit 3.

Specifically, a few of a pivot axis X defining bearing pin 24 are provided, which connect the intermediate ring 21 and the base ring 14 with each other and pass through sleeves 13, which are molded onto the support frame 13.
  • the recessed luminaire 1 finally includes a filter retaining ring 25 whose outer diameter is selected so that it can be inserted into the intermediate ring 21 from the underside thereof.
  • the filter ring 25 has two recesses 26, which engage with the sleeves 13 a of the support frame 13 when the filter retaining ring 25 is inserted into the intermediate ring 21.
  • 26 U-shaped spring members 27 are arranged in the region of the recesses with upward opening, which are elastically expanded when the recesses 26 engage with the sleeves 13 a, and clamp the sleeves 13 a by their elastic restoring force.
  • the elastic spring force is chosen so that the filter retaining ring 25 is also pivoted in a pivoting movement of the support frame 13 and thus the light unit 3 relative to the intermediate ring 21.
  • the spring force should be less than the clamping force with which the intermediate ring 21 is fixed in the mounting ring 4, so that the filter retaining ring 25 can be deducted from the intermediate ring 21, without the intermediate ring 21 detached from the mounting ring 4.
  • an inverted U-shaped spacer 28 is provided at the top of the support frame 13, which specifies a minimum clearance, the recessed luminaire 1 must have in the installed state.
