Definitions

  • the present invention relates to a holder for attaching a luminous element to a ceiling element or to a wall element, comprising a substantially cylindrical base body which extends along a longitudinal axis from a base body start to a base body end and has an outer surface, an element on the outer surface is arranged for adjustable fixing in the direction of the longitudinal axis, in particular an external thread, with at least one spatula element being arranged in the area of the base body end, which spatula element protrudes from the base body in a first direction, the first direction having at least one directional component, which directional component is normal lies on the normal plane standing on the longitudinal axis.
  • Recessed luminaires which for the most part sit inside a ceiling or wall element, are used in buildings, such as houses, or in structures and structures, such as canopies and tunnels. In this case, brackets are usually used that securely fix the luminous element on the ceiling or wall element.
  • EP 3 434 964 A1 For example, a holder for attaching a luminous element to a ceiling or wall element is known, which can be used with different ceiling or wall constructions and offers an optimal hold in a putty or plaster layer. In EP 3 434 964 A1 however, it is neither described nor is there any indication of whether and how the luminous bodies may be cooled.
  • cooling elements may be necessary, which have the task of dissipating the heat loss from the luminous element as well as possible to the environment in order to keep the operating temperature of the luminous element low.
  • cooling elements that have a large surface are preferably used.
  • EP 3 428 509 A1 a holder for mounting an electrical assembly, in particular a luminous element, on a ceiling or wall element.
  • the electrical assembly includes, among other things, a cooling element for cooling a supply board.
  • a disadvantage of the holder known from the prior art is that only luminous bodies that are directly connected to a cooling element can be built into it. This means that when the luminous element is replaced, not only the luminous element but also the cooling element connected to the luminous element must be removed from the holder. In order for this to be possible, the diameter of the cooling element must not be larger than the diameter of the luminous element. In order to nevertheless enable sufficient cooling, the cooling element must therefore have a corresponding height. As a result, the mounting depth of the bracket is great.
  • the holder can only be adapted to a limited extent to the thickness of a layer of filler or plaster applied to the ceiling or wall element.
  • bracket should be attached to the wall or ceiling flush mounting of the luminous element a thickness of a filler layer or plaster layer applied to a ceiling element or a wall element can be adapted.

  • the cooling element now has a larger diameter, the installation depth can be reduced with the same cooling performance.
  • the diameter of the base body in which the luminous element is inserted can be kept relatively small in accordance with the diameter of the luminous element because when the luminous element is changed, only the luminous element actually has to be removed from the basic element, but not the cooling element, which is used when changing the Luminous body remains in the holder. In this respect, the maintenance of the system consisting of the holder and the luminous element is also facilitated by the separation of the luminous element and the cooling element for the luminous element.
  • the plate element can be, for example, a gypsum fiber board which has a cylindrical shape at least in sections.
  • a thread is preferably used as an element for adjustable fixing in the direction of the longitudinal axis.
  • Such an external thread on the outer circumferential surface of the base body enables the base body to be attached to the plate element. It would be conceivable that the base body with its external thread is screwed directly into the plate element, an inner surface of the plate element delimiting the opening being cut at least in sections by the external thread.
  • the base body could be held in the opening by means of an internal thread of a counter-element, for example a nut, which is in engagement with the external thread.
  • the counter-element can be fixed on a rear side of the plate element before the plate element is built up, for example fastened or glued in a form-fitting manner.
  • the counter-element is fastened, for example glued, in the opening.
  • the fastening element is arranged in the opening and locked or tightened with the counter element on the back of the plate element so that the counter element does not need to be additionally fixed or glued to the back of the plate element.
  • one or more latching elements could also be provided on the base body, which engage in corresponding counter-elements on the plate element, for example in counter-elements in the opening of the plate element.
  • the base body can be pushed and fixed into positions along the longitudinal axis defined by the locking elements.
  • the putty element forms a protruding defined boundary up to which the putty or plaster layer is applied.
  • the filler element enables a well-defined, flush finish of the filler or plaster layer to the base body to be easily created.
  • the spatula element has one or more recesses into which a corresponding tool can be inserted in order to be able to rotate the base body without difficulty.
  • a corresponding tool can be inserted in order to be able to rotate the base body without difficulty.
  • it can be a slot-shaped recess into which a screwdriver can be inserted.
  • the at least one cooling element is behind the plate element when viewed in the direction of the longitudinal axis arranged if it is assumed that the front of the plate element faces into the room to be illuminated when the plate element is attached to or in a ceiling or wall element.
  • the cooling element and the start of the base body are connected to one another by means of a screw connection.
  • the cooling element and the start of the base body are connected to one another by means of a rivet connection or an adhesive connection.
  • the connection between the cooling element and the base body does not have to be detachable, because the cooling element does not have to be dismantled after the holder has been installed in a ceiling or wall element and is also not accessible without removing the ceiling or wall element.
  • cooling elements it would also be conceivable for several cooling elements to be arranged one behind the other and / or next to one another behind the plate element, as seen in the direction of the longitudinal axis.
  • the cooling element has a larger diameter than the opening of the plate element.
  • diameter is understood to mean a shortest distance between those two points on a surface of the cooling element which points are most distant from one another.
  • the larger diameter of the cooling element compared to the opening of the plate element ensures good cooling.
  • the height of the cooling element can be reduced as a result, since most of the cooling element extends normal to the longitudinal axis, whereby the installation depth of the holder according to the invention is reduced.
  • the geometric shape of the cooling element can vary.
  • the cooling element can have an at least partially polygonal shape or preferably an at least partially circular shape.
  • the cooling element can have the shape of a polygon or at least in sections preferably have the shape of a cylinder at least in sections.
  • a steady smooth contour of the cooling element or elements, in particular the circular shape prevents the cooling element from getting stuck when rotating on other devices, for example on the fixing elements for fixing the plate element on a ceiling or wall element, or on cables that run between the ceiling or wall element and solid wall.
  • the at least one cooling element is a flat cooling plate that is oriented normal to the longitudinal axis.
  • the corresponding alignment also results in a particularly small installation depth of the holder according to the invention.
  • the cooling plate has at least one opening, on the one hand to improve the air circulation and on the other hand to save material and weight of the cooling plate.

  • the diameter of the cooling element is at least twice as large as the opening of the plate element. On the one hand, this results in good cooling of the luminous element and, on the other hand, it ensures a small installation depth of the holder according to the invention. As a rule, the diameter of the cooling element is smaller than a diameter of the plate element. This has the advantage that the bracket, comprising the cooling element mounted thereon, can in principle be inserted into the ceiling or wall element from both sides.
  • the holder comprises at least one connecting element, which connecting element is arranged between the base body and the cooling element. That is, the connecting element is arranged behind the plate element, seen in the direction of the longitudinal axis, and is used to mechanically connect the base body and the cooling element.

That is to say, the connection board is arranged behind the plate element and in front of the connecting element, as seen in the direction of the longitudinal axis. This ensures that the connection board is not in direct contact with the cooling plate, since it is spatially separated from the cooling element by the connecting element.

This offers resistance to unwanted twisting. Nevertheless, the base body can be continuously adjusted until the bracket is plastered in. This means that the base body can be adapted at any time to the thickness of a layer of filler or plaster that has yet to be applied.
