Definitions

  • the present invention relates to a downlight having a ring-like mounting frame to be mounted in the region of a ceiling mounting opening and a so-called light carrier to be fastened to the mounting frame with a lamp head located thereon.
  • the invention relates to a downlight, in which the light carrier is reversibly attached to this by means of rotation relative to the mounting frame.
  • a "downlight” usually lights are designated, which are provided for attachment to a ceiling of a room to be illuminated and designed for a light output predominantly downwards. These are usually so-called. Recessed luminaires, which are thus designed so that they can be installed in the mounting hole of a suspended ceiling element, for example, a so-called. Rigipsdecke.
  • Such recessed ceiling lights in the form of downlights are known in different configurations.
  • a classic embodiment is that the lamp or the light carrier with the actual lamp head, which then includes the light source (s), is approximately circular. In this case, a ring-like so-called.
  • Mounting frame is then first fixed to the ceiling and the light carrier with the lamp head located thereon then releasably connected to the mounting frame.
  • Such a recessed ceiling light is from the DE 20 2010 002 646 U1 known to the applicant, and further offers the advantage over conventional recessed lighting that further security devices secure the light carrier against accidental unlocking by twisting.
  • this mounting frame serves to facilitate the installation of the downlight and subsequent repair or maintenance measures. Namely, it is merely the mounting frame firmly connected to the ceiling construction, for example. Via a screw or a special clamp connection and possibly then also at least partially plastered.
  • the actual lamp however, so the light carrier with the lamp head located thereon, however, is designed such that it can be fastened in a detachable manner to the mounting frame.
  • the actual mounting of the essential components of the downlight can therefore only take place at a later date, when all further preparatory work, esp. Fixing and plastering of the mounting frame are already completed.
  • connection is made such that the light carrier with the lamp head located thereon can be quickly, easily and reliably attached to the mounting frame.
  • fastening means in the form of a screw-type connection, in particular a so-called bayonet connection, have prevailed in which the light carrier is attached to the mounting frame from the underside and then rotated relative thereto.
  • corresponding guide projections which are usually arranged on the light carrier and engage in guideways of the mounting frame or slide along the top of such guideways, then carried an attachment of the light carrier to the mounting frame. To release the connection of the light carrier must be rotated only in the opposite direction relative to the mounting frame.
  • the present invention is accordingly based on the object to provide a novel solution in which the above-described problems are avoided.
  • the downlight according to the invention is in turn designed such that the attachment of the light carrier to the mounting frame by means of rotation of the light carrier relative to the mounting frame.
  • This is esp. Provided in the context of a bayonet connection.
  • additional securing means are provided, which secure the light carrier in its mounting position, ie in the position attached to the mounting frame, against rotation in unlocking.
  • a downlight is proposed with an annular mounting frame to be mounted in the region of a ceiling mounting opening and a light carrier to be fastened to the mounting frame, wherein the mounting frame and the light carrier are designed such that the fastening by means of rotation of the light carrier relative to the mounting frame, and wherein according to the invention additional securing means are provided which secure the light carrier in a mounting position against rotation in Entriegelungsraum, wherein the attachment of the light carrier is carried on the mounting frame by means of a bayonet lock.
  • the securing means further comprise a locking element arranged in particular on the mounting frame, which locking element is blocked in the mounting position of the light carrier by a limiting element arranged in particular on the light carrier.
  • the locking element and the limiting element are formed such that upon rotation of the light carrier relative to the mounting frame in the direction of the mounting position, the locking element independently passes or overcomes the limiting element.
  • the limiting element is formed by a so-called. Run-on slope and at the same time the locking element is mounted vertically adjustable.
  • the height-adjustable locking element can slide along the ramp and is thereby deflected until it has passed and then snaps back into a corresponding locking position in which the locking element for rotation in the opposite direction by the limiting element or the ramp is blocked. In this way can very simple and with few additional measures, the solution according to the invention can be realized.
  • the height adjustability of the locking element can, for example, be realized in that the locking element is formed by a locking spring, which is arranged on the mounting frame and has an opening provided for receiving the light carrier interior facing locking projection.
  • a locking spring which is arranged on the mounting frame and has an opening provided for receiving the light carrier interior facing locking projection.
  • the arrangement of the various components is preferably designed such that accidental release of the lock according to the invention is prevented. Only by specific measures, this lock can be solved, including, for example, be provided that on the mounting frame an unlocking is formed, which allows the insertion of a tool for lifting the locking spring. For example.
  • This opening can be very narrow, so that only by a very narrow object such as a paper clip or a narrow screwdriver, which must be specifically introduced into this opening, the lock can be solved.
  • this measure provides sufficient security; on the other hand, the effort required to release the lock, if the light carrier is deliberately to be removed from the mounting frame, is not very high.
  • a so-called limiting projection is provided by which a rotation of the light carrier in the locking direction is limited. That is, this restricting protrusion represents the end position of the light carrier when being rotated for mounting, and is preferably arranged such that the locking protrusion of the above-mentioned locking spring fits into the clearance between the restricting protrusion and the ramp. As a result, a defined mounting position of the light carrier relative to the mounting frame is achieved.
  • the light carrier itself can, for example, consist of plastic. It would also be conceivable, however, to make it from a different material, esp. Sheet metal or aluminum.
  • the solution according to the invention leads in particular to advantages when the lamp head itself is again adjustable, in particular rotatable, on the light carrier. That is, a particularly preferred embodiment of the present invention are so-called. Kardanditionn. However, the Concept of the invention, of course, also be used in rigidly arranged on the light carrier lamp heads use.
  • FIGS 1 and 2 show first in different views, the essential components of an inventively designed, generally provided with the reference numeral 100 downlights.
  • This is intended to be mounted in an approximately circular and not shown mounting hole of a suspended ceiling.
  • the light is emitted primarily to the underside of an area to be illuminated.
  • Such downlights are used in a variety of ways, both for the illumination of workplaces and in rooms of public buildings, such as museums and the like.
  • first element is preferably permanently and firmly connected to the ceiling and all other components can be detachably mounted on this first element.
  • a permanently connected to the ceiling element is a so-called.
  • Mounting frame or mounting frame 50 is used, which is adapted in terms of its shape to the mounting opening of the ceiling, in the present case is thus designed like an annular.
  • the mounting frame 50 has an angled configuration with an outwardly directed circumferential flange 51 resting on the ceiling in the mounted state and a peripheral web 52 extending into or through the opening of the ceiling
  • the circumferential flange region 51 which then forms the actual installation opening for the other components of the downlight with its inner edge, serves to compensate for any irregularities in the ceiling installation opening or to conceal it.
  • this flange 51 is partially plastered after attachment to the ceiling, so that a particularly inconspicuous transition between the ceiling and the other elements of the lamp 100 is achieved.
  • the attachment of such a mounting frame 50 on the suspended ceiling can be done in many ways, for example. Screw are known, which would be conceivable in the present case. In this case, usually, the outwardly projecting portion of the flange 51 has a hole pattern or the like, by which screwing with the plaster ceiling is facilitated. In the illustrated embodiment, however, the attachment is carried out by means of special locking elements 55 which are arranged distributed on the circumference of the mounting frame 50. These locking elements are esp. Formed by height-adjustable and outwardly pivotable tabs, which initially in the in FIG. 1 shown configuration are aligned vertically downwards, so that they can be easily passed through the mounting hole when inserting the mounting frame 50 to the ceiling.
  • the lamp head 30 includes first of all the light sources, for example. In the form of one or more LEDs whose light is emitted by means of a reflector not shown in detail to the bottom. The heat generated during the operation of the light sources heat is discharged by means of a heat sink 31 to the ambient air, which - according to the representations - extends to the top and is arranged in the mounted state within the intermediate area between suspended ceiling and raw ceiling.
  • the power supply of the various components of the lamp head 30 can be effected by means of a separate control and power supply unit or a correspondingly integrated unit.
  • the lamp head 30 can thus be designed in different ways, for releasable attachment to the mounting frame 50 of this so-called.
  • Light carrier 10 is held, which is designed according to the invention in the manner described in more detail below.
  • the lamp head 30 is adjustably arranged on the light carrier 10. Esp. in this case, a so-called. Gimbal lamp is to be realized, which thus allows pivoting of the lamp head 30 in different directions, esp. But also allows twisting.
  • Corresponding fastening means which offer such adjustment possibilities are already known from the prior art.
  • the lamp head 30 is held only rotatably on the light carrier 10 or even rigidly arranged on this.
  • an annular aperture 35 is additionally provided in the illustrated embodiment, which is attached for optical reasons on the underside of the light carrier 10. However, this is not absolutely necessary for the realization of the inventive concept.
  • the releasable attachment of the light carrier 10 to the mounting frame 50 is effected in the present case by a so-called. Bayonet connection.
  • 50 corresponding guide tracks 53 are provided on the inside of the upwardly directed web 52 of the mounting frame, which are accessible via insertion openings 54 which extend to the underside of the mounting frame 50 out.
  • three guide tracks 53 with corresponding insertion openings 54 for which purpose correspondingly distributes three corresponding projections on the outer circumference of the light carrier 10 are arranged.
  • the preferably made of plastic light carrier is in this case designed pot-like with a circular base surface on which the attachment of the lamp head 30 takes place, and a circumferential, slightly inclined shell surface on which the bayonet projections are formed.
  • the latter is thus attached to the mounting frame 50 from the underside in such a way that the outwardly directed projections engage in the insertion openings 54. Subsequently, the light carrier 10 in the arrow direction (s. FIG. 1 ), so that the projections slide along the tops of the guideways 55 until the end position or mounting position has been reached. In this case, then provide the guideways 53 that the light carrier 10 can no longer fall out of the opening of the mounting frame 50 to the bottom.
  • a first essential element of the solution according to the invention is a so-called. Locking spring, which in FIG. 4 shown individually and provided with the reference numeral 20.
  • the arrangement of the locking spring on the mounting frame 50 may FIGS. 5 and 6 be taken in more detail.
  • the locking spring 20 initially has a slightly arcuate, in the later use horizontally oriented web 21, which has a bore 22 at one end and at the opposite end a guide recess 23. Aligned angled to this web 21 is a locking projection 25, which forms a downwardly facing, initially slightly tapered, but then just expiring pin. This projection 25 is on a longitudinal side of the horizontal web 21, from the middle slightly in the direction of Guide opening 23 arranged displaced towards. Overall, the locking spring is formed by a correspondingly punched and later bent sheet metal part.
