Definitions

  • the invention relates to a recessed ceiling light according to the preamble of claim 1.
  • a recessed ceiling light has become known, for example, from EP-A-O 304 878.
  • Such recessed ceiling lights have, for example, an essentially rotationally symmetrical reflector, to the end of which is facing away from the light exit opening, a feed housing is fastened at the top or on the side, which housing e.g. can accommodate a transformer or other electrical ballast units and can also have a relatively large installation volume.
  • the known recessed ceiling luminaire To mount the known recessed ceiling luminaire, first its holder - with the infeed housing attached to it - is lifted into the ceiling cavity through the recessed ceiling opening and locked there, for example, via screw-adjustable retaining springs on the surface of the ceiling panel facing the ceiling cavity. Then the reflector is installed and finally the lamp is inserted.
  • the object of the invention is to create a recessed ceiling light which is satisfied with a relatively low clearance height of the ceiling cavity and also avoids the disadvantages of the known.
  • this object is achieved in that the feed housing is connected to the main joint by means of a cross member and that the cross member can be folded from a vertical pre-assembly position into a horizontal installation position.
  • the invention Due to the movable articulation of the feed housing on the reflector or on its holder, the invention has taken the bulky construction from the otherwise known arrangements.
  • Recessed ceiling light the feed housing can be kinked at its articulation point and the entire light unit can thus be pushed "around the corner" into the ceiling cavity with little installation or pivoting space through the installation opening.
  • the recessed ceiling light according to the invention therefore requires only a small amount of installation space, that is to say only a small clear height of the ceiling cavity.
  • the feed housing is connected to the main joint by means of a cross member. This traverse can be folded from a vertical pre-assembly position into a horizontal installation position.
  • a particularly low clear installation height is achieved in a further embodiment of the invention in that at least one joint, the main joint, is arranged on the reflector or on its holder close to the light outlet opening.
  • the traverse expediently forms an articulated fork with two free fork legs, the free ends of which are articulated, in particular at diametrically opposite locations, to form the main joint on the reflector or on its holder.
  • the feed housing for example containing a transformer or ballasts, is spaced from the top of the ceiling panel, that is to say it is kept sufficiently free within the ceiling cavity.
  • This enables the invention in that on the free side of the feed housing facing away from the joint there is provided a support which supports the latter in its installed position in the ceiling cavity.
  • This support can be designed as a folding support in such a way that it is held on the feed housing via a support joint and can be aligned in its vertical installation position by means of gravity.
  • the support joint expediently has a straight hinge axis which extends essentially parallel to the ceiling surface.
  • a known recessed ceiling light is generally designated by the reference number 10A.
  • the known lamp 10A is installed inside a ceiling cavity 11A with the clear height H1.
  • the recessed ceiling light 10A has a reflector 12, which receives a lamp 13 shown in broken lines, which emits its light downwards through a light exit opening 14.
  • the light exit opening 14 is circular; the reflector 12 accordingly has an approximately rotationally symmetrical shape, for example with a parabola as the generator.
  • the reflector 12 On its upper side 15 facing the light exit opening 14, the reflector 12 has a feed housing 16 fastened there, which receives a transformer or other electrical components and also through openings 17 for electrical feed cables, not shown in detail.
  • the installation state of the known recessed ceiling light 10A according to FIG. 1 is accomplished by means of support arms 30 of a holder 23, which are known per se and are not shown in detail in detail, and can be locked in place.
  • FIG. 2 which shows the recessed ceiling light 10B according to the invention, shows that the required installation height H2 of the ceiling cavity 11B is essential is less than the height H1 of the ceiling cavity 10A of the known arrangement according to FIG. 1.
  • the feed housing 26 is connected to the reflector 12 or to its holder 23 by means of a cross member 24 via a main joint 25.
  • the main joint 25 has a straight joint axis, which is denoted by x and which has to be imagined as projecting vertically into the plane of the drawing.
  • the feed housing 26 according to FIG. 2 is suspended below the cross member 24.
  • a support 28 is held by means of a support joint 29 and can thus be aligned by gravity in the vertical installation position of the support 28.
  • the support joint 29 has a straight joint axis z which extends parallel to the ceiling face 22.
  • the cross member 24 can first be placed vertically before the assembly, the feed housing 26 with the support 28 folded approximately horizontally through the circular installation opening E of the ceiling panel 21 and then be folded down horizontally in the further course of the insertion process, while the holder 23 with the support arms 30 reaches its installation position according to FIG. 2.
  • the reflector 12 can also be inserted into the installation opening E and screw-connected to the holder 23, after which the lamp 13 can be installed.
  • a recessed ceiling directional spotlight 10B is shown as a concrete embodiment of the invention.
  • the reflector 12 of the recessed ceiling light 10B is held in a suitable manner on a holder 23 designed as a recessed ceiling ring, for example by means of attachment extensions 31.
  • a lamp holder fitting 32 which carries a low-voltage halogen lamp 13, is mounted by means of two hinge brackets 33 on the holder 23 about a horizontal hinge axis 34 and thus can be tilted relative to the reflector 12.
  • the lamp 13 is supplied by means of an electronic transformer, which is accommodated in the feed housing 26, via electrical lines, not shown.
  • a crossbeam 24 designed as an articulated fork is by means of the main joint 25 at two diametrically opposite points A and B, which are the main joint 25 represent hinged to the bracket 23.
  • the articulation points A and B are arranged close to the light exit opening 14 practically immediately above the upper surface 20 of the ceiling panel 21. This arrangement favors a low clear installation height according to FIG. 2 and at the same time a low center of gravity of the relatively heavy feed housing 26.
  • FIGS. 3 and 4 An additional installation or assembly flexibility is achieved in accordance with the specific embodiment of FIGS. 3 and 4 in that the feed housing 26 is articulated on the end of the fork-shaped cross member 24 facing away from the main joint 25 by means of a secondary joint 35.
  • the straight joint axis y of the secondary joint 35 extends horizontally and parallel to the joint axis x of the main joint 25.
  • the secondary joint 35 in the specific exemplary embodiment enables the relatively heavy installation housing 26 to be tilted and snug on the upper surface 20 of the ceiling panel 21 can support in terms of a favorable weight distribution.
  • the vertical position of the lamp 13 according to FIG. 3 is shown in dashed lines. 4 shows the lamp holder fitting 32 in the vertical position of the lamp 13.
  • the ceiling panel 21 is not shown in FIG. 4.
  • the two fork legs of the cross member 24 are provided with the reference number 36.
