Definitions

  • the invention relates to a recessed light, in particular for halogen lamps, according to the preamble of claim 1.
  • recessed lights are called ceiling lamps especially installed in hollow ceilings.
  • the lamp frame carries the lamp holder, the reflector and holding means for attaching the recessed light to one Wall section.
  • a problem with known recessed luminaires arises from the relatively high temperature, which requires special installation measures.
  • the insulation material around the recessed luminaire a certain safety distance adhere so that an air space is created behind the recessed light.
  • this requires a large amount of work during assembly and on the other hand is the insulation effect of the hollow ceiling with respect to heat and Soundproofing impaired. Nevertheless, there is insufficient security regarding Risk of fire guaranteed.
  • Well-known are also suitable for installation in solid wood Recessed lights not because of the known temperature problems. It is therefore an object of the invention to a downlight of the type mentioned create, in which the built-in rear part of the lamp only low temperature loads is exposed and which is particularly suitable for installation in isolated Hollow ceilings are suitable. This object is achieved according to the invention with a built-in lamp solved, which has the features in claim 1.
  • the lamp frame is fixed in a built-in pot, which is the recessed part of the Luminaire protects against heat radiation.
  • Installation pots on lights are for example already known from US-A-4 821 161 or from CH-A-687 564. However, these built-in pots have no cutouts for holding devices on which the lamp frame can be attached.
  • the lamp frame is not consistently from the hot part of the lamp or Reflector separately. This separation is in the recessed light according to the invention achieved by a connector that has poor thermal conductivity and via which the reflector is connected to the lamp frame.
  • the connector can be made of a ceramic material or a heat-resistant material, for example Plastic material exist.
  • the connector is preferably directly a ceramic socket for the lamp.
  • Such sockets are, for example, for halogen lamps as sockets in use.
  • the frame is mounted so that the reflector is on one side and on the other side the lamp frame is attached.
  • the holding means advantageously have at least two resilient clamping brackets, which are biased such that they are resilient against the back of a wall section be pressed.
  • the built-in pot has one for each clamp bracket Slotted edge of the recessed pot. In this way, the lamp frame can be simple be installed in the built-in pot and the clamps have an unrestricted Freedom of movement.
  • the built-in pot is preferably cylindrical so that it passes through an opening can be inserted into a wall section which is only slightly larger than the outside diameter of the built-in pot.
  • the lamp frame has one Support bracket, which is screwed to the mounting pot above the recesses for the holding means is.
  • the holding bracket obviously also carries the holding means itself. Another attachment of the lamp frame, for example on the closed The end of the built-in pot would be easily conceivable.
  • the built-in pot advantageously has in the area of the connection to the lamp frame essential flat wall sections. This makes it non-rotatable for assembly Installation of the lamp frame guaranteed.
  • the lamp frame advantageously has an annular cover for covering the installation opening, but at the same time also as an abutment for clamping the lamp frame serves on the wall section.
  • the reflector is preferably held in the diaphragm in such a way that between the inside edge of the bezel and the outside edge of the reflector an all-round air gap remains. As a result, heat transfer from the Avoid reflector on the panel and thus also on the wall section. On the other hand the air gap also ensures air exchange in the built-in pot.
  • the built-in pot can be made especially inexpensively from plastic material.
  • ceramic material could also be used for special purposes.
  • a preferably electronic transformer required the Mains voltage reduced.
  • Such a transformer can directly in the hollow ceiling be arranged next to the built-in pot, the outside of the transformer is also surrounded by insulation material without an air gap.
  • the transformer too gives off a certain amount of heat. However, this adds up together with the heat emitted by the recessed light does not become an impermissible value.
  • Known recessed lights also had to use the transformer because of this addition effect be surrounded by a relatively large circumferential air space.
  • the downlight 1 shown in Figure 1 consists essentially of a lamp frame 2 ( Figure 2) and from a built-in pot 5.
  • the lamp frame has a approximately U-shaped support bracket 8 whose U-leg with an annular aperture 9 are connected.
  • the part of the panel that is visible from the outside has a somewhat raised edge Outer edge 14 and an inner edge 10.
  • the cover 9 covers this Way the installation opening 31, but only touches a wall section 24 in a straight line in the area of the outer edge 14.
  • the diaphragm 9 goes into a cylindrical inner wall 13 about.
  • This inner wall is welded to the bracket 8.
  • the distance between the two U-legs of the bracket 8 is slightly larger than the outer diameter the inner wall 13.
  • the inner wall is thereby at a distance from it surrounding built-in pot 5 held.
  • a recess 23 is also arranged in each of the two U-legs of the support bracket 8, in which a torsion spring 22 is held.
  • Each spring is with a spring clip 3, 3 'connected, which is pivotable about the axis of the spring 22 and against the Aperture 9 is biased.
  • the two spring clips are used to install the lamp pivoted all the way up so that it is pushed through the installation opening 31 can be. Then the spring clips clamp against the back of the wall section 24 and in this way press the panel 9 against the outside of the wall section 24.
  • a lamp holder screwed on ceramic For example, in this lamp holder a halogen light bulb 12 can be inserted.
  • a reflector 4 is attached, which also infrared radiation largely reflected downwards. The reflector 4 is in the center the aperture held that between the inner edge 10 of the aperture and an air gap 21 remains on the outer edge 11 of the reflector. This is practically none Immediate heat transfer from the reflector to the lamp frame possible.
  • the built-in pot is cup-shaped and essentially cylindrical, its side walls made of fabrication technology Reasons, however, have a low mold release of approx. 1 °.
  • Three spacers 16 are arranged on the rear wall 33 of the built-in pot 5. This serve to accommodate a disc-shaped cover 17 (Figure 1), which the Transformer cable 30 fixed.
  • the cover 17 is fastened by means of a Screw that can be screwed into a screw sleeve 20.
  • the cable 30 is passed through a cable opening 19 into the interior of the mounting pot.
  • FIG. 4 shows a hollow ceiling 28 with a recessed luminaire attached to the wall section 24 1.
  • a transformer 29 is arranged directly next to it.
  • the insulation material 25 is air-tight around the recessed light 1 and around the Packed transformer 29. This is an optimal insulation effect in the area the recessed light guaranteed.
  • the same arrangement can also be mounted in an insulated cavity wall.
