Definitions

  • the invention relates to a recessed spotlight for ceiling or rear wall mounting and in particular to a recessed spotlight with at least one fluorescent lamp.
  • DE 40 16 531 A1 describes a recessed spotlight with a base frame to be fastened to an opening in the ceiling or wall, with three projecting rods to which a support housing is fastened, which contains the electrical components and sockets required for lamp operation.
  • the base frame receives a first reflector surrounding the lamp, while another reflector, which is designed as a roof reflector, is fastened to the underside of the support housing.
  • the lamp protrudes from the underside of the support housing into the space surrounded by the first reflector.
  • the lamp is arranged in the longitudinal direction of the recessed spotlight.
  • a recessed spotlight with a lamp arranged transversely is known from DE 32 49 401 C2.
  • This recessed spotlight does not have a base frame but a housing that surrounds all lamp parts.
  • a recessed spotlight which has a base frame for wall or ceiling mounting surrounding a first reflector, to which a support housing for electrical components is fastened behind the first reflector. At an angle projecting parallel to the first reflector, the support housing has a holder for a lamp running transversely to this reflector, which projects through an opening in the reflector.
  • a second reflector is arranged as an internal reflector in the front luminaire area, that is to say in the area of the wall or ceiling opening. There is no roof reflector covering the lamp. The receiving area for the electrical components arranged above the lamp increases the required installation depth of the recessed spotlight.
  • Recessed spotlights are known from US Pat. No. 4,947,297 and DE 87 06 542 U1, which have a single reflector which surrounds the lamp arranged transversely therein and at the same time is designed as a roof reflector.
  • a reduced installation depth can be obtained here, but the construction of the recessed spotlight is not very stable. Because of the weight of the housing which projects laterally from the reflector and contains the electrical components, deformations of the reflector can occur.
  • the invention has for its object to provide a recessed spotlight that requires a small installation depth with a solid mechanical structure and is inexpensive to manufacture.
  • the support housing consists of a surrounding area surrounding the lamp and the second reflector, which is adjoined laterally by a receiving area in the manner of a cantilever.
  • the roof reflector covering the lamp is thus fastened in the interior of the housing, specifically in the surrounding area to which the support frame also acts.
  • the receiving area protrudes laterally, so that it does not increase the installation depth.
  • the carrying case thus has three functions: it serves to accommodate the electrical components, such as ballasts for the operation of fluorescent lamps, connecting devices and the like; it connects the upper ends of the columns of the base frame and it forms a surrounding area for the second reflector, which is thus protected against damage.
  • the support housing is preferably formed in one piece from the surrounding area and the receiving area, so that it is rigid in itself.
  • the area of coverage is below (and preferably also open at the top), while the recording area is provided with a floor. Both areas can be provided with merging side walls of the same height.
  • the recessed spotlight is easy to manufacture at low cost.
  • the support housing forms the support structure for the electrical components and for some of the lighting components that are attached to it or in it.
  • the recessed spotlight allows various modifications in a simple manner.
  • an interchangeable support wall for lamp holders can be provided in the receiving area of the support housing.
  • Different support plates with different numbers and / or arrangements of lamp holders can be used for a single-lamp or a multi-lamp version of the recessed spotlight.
  • the second reflector surrounded by the surrounding area can also be very easily installed and replaced. It only needs to be placed on corresponding projections that protrude inward from the surrounding area.
  • the recessed spotlight has a base frame 10 which is attached to the wall or ceiling through an opening in a wall or ceiling.
  • the base frame 10 consists of an annular mounting frame 11 which is supported with a support flange 12 on the front of the wall opening.
  • Three columns 13, 14, 15 project axially parallel to the rear from the rear of the frame 11 and are rigidly connected to the mounting frame 11.
  • Clamps 16 are attached to the columns 13, 14, 15 so as to be longitudinally displaceable. These clamps each have a support arm directed forward with a gripping surface 17 for engaging on the rear of the wall.
  • the columns 13 are threaded, on each of which sits a nut 18 which supports the clamp 16 to the rear.
  • a frame 19 is inserted into the mounting frame 11, which covers the mounting frame on the visible side.
  • the frame 19 also serves to support the ring-shaped first reflector 20, which is inserted from the front into the mounting frame 11 before the frame is mounted and which is held by the frame 19 after the frame has been installed.
  • the first reflector 20 has a diameter that decreases towards the rear and it is designed, for example, as a parabolic reflector.
  • the reflector 20 can have a circular or a different cross section.
  • the support housing 21 is mounted with screws 22 on the three columns 13, 14, 15.
  • the support housing 21 consists of two areas connected to one another in one piece, namely the surrounding area 23 arranged coaxially to the base frame 10 or reflector 20 and the receiving area 24 projecting laterally therefrom. Both areas 23 and 24 have side walls of the same height.
  • the surrounding area 22 is annular or cylindrical.
  • Holders 25 and 26 for the ends of the columns 13 and 14 of the base frame 10 are located on two diametrically opposite sides of the peripheral region 23.
  • a third holder 27 is provided in the bottom 28 of the receiving region 24.
  • the plane of the brackets 25 and 26 is perpendicular to the plane in which the axis of the base frame 10 and the third bracket 27 lie.
  • the three brackets 25, 26 and 27 thus form an isosceles right-angled triangle. All brackets lie on a common circle around the longitudinal axis of the base frame 10 or the first reflector 20.
  • the brackets 25, 26, 27 or the columns 13, 14 and 15 are each at an angular distance of 90 ° to one another, whereby no bracket and no column is arranged opposite the bracket 27 or the column 15.
  • Support studs 28 are provided on the columns 13, 14 and 15, on which a flange 29 rests at the lower end of the surrounding area 23, the flange 29 being fixed by the nuts 22.
  • the holder 15 is located in the part of the receiving area 24 adjoining the surrounding area 23, that is to say approximately in the central area of the length of the entire support housing 21.
  • the receiving area 24 is essentially box-shaped. In addition to the floor, it has 28 side walls and it can be closed by a cover (not shown). The interiors of receiving area 24 and surrounding area 23 merge into one another without a partition, the side walls of both areas adjoining one another.
  • the surrounding area 23 On the side facing away from the receiving area 24, the surrounding area 23 has an opening 31 which extends over part of the circumference of the surrounding area. This opening 31 is used for installing and replacing the lamp 32.
  • the lamp 32 is an elongated fluorescent lamp which has a lamp base 33 at one end.
  • the lamp base 33 is inserted into a lamp holder 34.
  • the lamp socket 34 is fastened to an exchangeable support wall 35, the side edges of which are guided in guide grooves 36 in the side walls of the receiving area 24.
  • the supporting wall 35 closes the interior of the receiving area 24 from the interior of the surrounding area 23.
  • the floor 28 of the receiving area 24 are molded on approaches 37 on which electrical components 38 can be mounted, to which ballasts, chokes, igniters and the like. may belong to the lamp operation.
  • connection devices 39 In a recess in the rear wall of the receiving area 24 there are connection devices 39 to which the supply lines (mains lines) can be connected. From these connection devices 39, wires (not shown) lead to the electrical components 38 and from these leads (not shown) to the lamp holder 34.
  • a second reflector 40 is arranged as a roof reflector, which covers the lamp 33 on the side facing away from the reflector 20.
  • the second reflector 40 is a two-dimensional reflector which can be easily produced by punching and bending and does not require any complex pressing process and no perforation.
  • the second reflector 40 extends with a constant profile cross section through the surrounding area 23 parallel to the lamp 32, its outer contour being circular.
  • Fig. 5 shows a two-lamp version of the recessed spot.
  • This recessed spotlight has the same base frame 10 and the same support housing 21 as the single-lamp version. The only difference is that another supporting wall 35a is inserted into the guide grooves 36, on which two lamp holders 34a and 34b are fastened next to one another.
  • the lamp base 33a or 33b of another elongated fluorescent lamp 32a or 32b is fastened to each of the lamp holders. 5, the second reflector 40 can also be replaced there.
  • This reflector 40 rests with its side edges on projections 42 which protrude inwards from the side wall of the surrounding area 23.
  • a sawtooth-shaped nose 43 (FIG.
  • the reflector 40 is arranged at the upper end of the surrounding area at the point opposite the receiving area in order to hold down the reflector 40.
  • the reflector 40 can thus, like the reflector 20, be assembled or disassembled without the use of tools.
  • the projection 43 is located on a narrow web 44 which bridges the circumferential opening 31 of the receiving area 23 at the upper or rear end.
