Definitions

  • the invention relates to a recessed spotlight which is primarily used as a ceiling spotlight in ceilings in order to direct light radiation specifically onto desired objects or locations.
  • Recessed spotlights which can be fastened with a mounting ring in a ceiling or wall and which have a rotating ring in order to rotate the lamp housing in the mounting ring. Furthermore, the lamp housing can be pivoted with respect to the rotating ring. The pivot axis of the lamp housing is perpendicular to the axis of rotation of the rotating ring, so that the lamp housing can be pivoted around two axes. This makes it possible to change the direction of radiation of the recessed spotlight in the installed state in the desired manner or to direct the spotlight to any point in the room.
  • the pivot axis of the lamp housing passes approximately centrally through the lamp housing.
  • brackets on the rotating ring between which the luminaire housing is mounted.
  • the lamp housing is pivoted in the opening of the rotary ring, the opening with respect to the lamp housing must have an excess in order to enable the pivoting.
  • the luminaire housing protrudes from the opening in every state and thus protrudes considerably into the room to ensure that the light outlet opening is exposed even with maximum pivoting.
  • a recessed spotlight which has a rotating ring which can be rotated in a mounting ring and in which the lamp housing is mounted.
  • the luminaire housing is connected to the rotating ring via a hinge part and can be fixed in different swivel positions.
  • an elastic pressure device acts on the wall of the lamp housing opposite the hinge part, which presses the lamp housing in the direction of the hinge part.
  • the disadvantage is that the hinge part must be dismantled for the assembly and disassembly of the lamp housing on the rotating ring. Replacing the lamp housing is therefore very difficult.
  • the invention has for its object to provide a recessed spotlight which is designed so that the lamp housing can be assembled and disassembled very easily with pivotability or rotatability about two axes extending at right angles to one another.
  • the luminaire housing is connected to the rotating ring along the swivel axis only by hook engagement.
  • the hook can either be attached to the luminaire housing or to the rotating ring and a pin that interacts with the hook on the other part. It is important that the lamp housing is only loosely hooked with the rotating ring along the pivot axis, so that it can also be freed from the rotating ring by lifting.
  • the resilient pressing element engages in locking elements of the lamp housing. As a result of the engagement of the pressure element, the pressure element only needs to receive a small spring force, which is sufficient to establish the contact between the pressure element and the locking element.
  • the spring force need not be so great that the entire luminaire housing is pressed against the swivel axis in order to maintain the swivel position through increased friction. Due to the small force exerted by the pressure element on the lamp housing, no hinge part is required to connect the lamp housing to the rotating ring, but only a loose hook engagement.
  • the lamp housing preferably has an essentially rectangular plan. While the mounting ring and the rotating ring are circular rings, the rotating ring has a rectangular recess, which is also taken up by the rectangular light outlet opening of the luminaire housing. Under a rectangular plan of the It should be understood that the part of the lamp housing which is seated in the recess of the rotating ring has essentially parallel and straight edges. The corners are preferably rounded.
  • the luminaire housing expediently has a substantially circular side wall on the side facing away from the pivot axis, on which the latching elements are provided.
  • the axis of curvature of the circular side wall coincides with the pivot axis, so that the circular side wall moves along the pressing element when the lamp housing is pivoted, without significant changes in distance occurring.
  • the recessed spotlight which is built into a wall or suspended ceiling, has a luminaire housing 10, which consists for example of plastic and has an essentially rectangular plan, as can be seen from FIG. 1.
  • the inside of the wall of the lamp housing 10 is at least partially mirrored, so that the lamp housing also forms a reflector.
  • elongated lamps 11, for example fluorescent lamps are arranged horizontally and extend essentially over the entire length of the lamp housing.
  • the end walls 10a and 10b of the lamp housing which run transversely to the lamps 11 run essentially planar and at right angles to the top wall 10c.
  • the side walls 10d and 10e running parallel to the lamps 11, on the other hand, are partially cylindrical, ie they are curved with a constant radius.
  • the inner sides of the longitudinal side walls 10d and 10e form a reflector which widens towards the light exit opening 12 and which directs the lamp light through the reflector opening 12.
  • the luminaire housing is closed off by a grid unit 13 which has V-shaped lamellae 14 directed transversely to the lamps 11 and which are provided in a retaining ring 15 which is inserted into the lower end of the housing body.
  • the lamps 11 are inserted with their lamp bases 11a into sockets 16 (FIG. 3), which are fastened in an additional housing 17.
  • the additional housing 17 is removably attached to the front wall 10a of the lamp housing 10 and it contains the auxiliary devices required for lamp operation, ie in addition to the sockets 16 also starters and the like. Openings 18 for the passage of the lamps are located in the end wall 10a 11. These openings 18 are enclosed by the additional housing 17.
  • the additional housing 17 has recesses at the upper end, which are placed on lugs 19 of the top wall 10c, so that the additional housing is pivotally hooked into the lugs 19.
  • a screw 20 which can be screwed into a threaded projection 21 projecting from the end wall 10a in order to securely fasten the additional housing 17 to the lamp housing 10.
  • the additional housing can be removed together with the sockets 16.
  • the recessed spotlight is fastened to a wall or ceiling using the circular mounting ring 22 which is inserted into a corresponding opening in the wall or ceiling 23 (FIG. 4).
  • a plurality of clamping pieces 24 are provided which engage behind the wall or ceiling 23 and can be tightened with a screw 25, so that the mounting ring 22 is firmly connected to the wall or ceiling 23.
  • a rotating ring 26 is rotatably held in the mounting ring 22.
  • the rotating ring which has a circular circumference, has a rectangular recess 27, into which the end of the lamp housing 10, or the grid unit 13, projects.
  • the rotary ring 26 is attached to the mounting ring 22 by means of slides 28 which are guided in radial guides on the rotary ring 26 and which each have a nose 29 projecting outwards. which engages over an inwardly directed leg 30 of the mounting ring 22. 2 has an inclined upper flank 31, so that the nose 29 is pushed radially inward by the leg 30 when the rotary ring 26 is pressed axially against the mounting ring 22. The rotary ring 26 then automatically engages on the mounting ring 22. When the rotating ring 26 rotates, the lugs 29 of the slide 28 slide along the leg 30 of the mounting ring 22. The rotating ring can thus be rotated 360 ° coaxially with the mounting ring.
  • the slides 28 are each biased radially outwards by a spring 32 (FIG. 1).
  • An actuating handle 33 projects downward from each of the two slides 28. This operating handle 33 protrudes through a (not shown) radial elongated hole of the rotary ring 26 so that the slide 28, which is located behind the rotary ring 26, is accessible from the front to move it radially inwards and to release the rotary ring from the mounting ring can.
  • an aperture ring 34 is fastened with a plurality of snap closures (not shown).
  • This diaphragm ring 34 covers the rotating ring 26 and the mounting ring 22 on the visible side. When the rotating ring 26 rotates, the diaphragm ring 34 also rotates while the mounting ring 22 is fixed.
  • the luminaire housing 10 can be pivoted about a pivot axis 35 which runs parallel to the planes of the mounting ring 22 and the rotating ring 26 and which is arranged near the opening edge 46 (FIG. 2) provided to continue the side wall 10d of the luminaire housing.
  • a pivot axis 35 which runs parallel to the planes of the mounting ring 22 and the rotating ring 26 and which is arranged near the opening edge 46 (FIG. 2) provided to continue the side wall 10d of the luminaire housing.
  • laterally projecting cantilever-like projections 36 are provided, each of which engages in a recess of the rotary ring 26 and there one grasp the recess bridging pin 37 of the rotary ring (Fig. 1).
  • the pins 37 thus form the pivot axis 35, around which the lamp housing 10 is pivotable relative to the rotary ring 26.
  • This pivot axis 35 is located outside of the plan taken by the lamp housing 10 in the position shown in FIG. 2.
  • the pivot axis 35 lies in a recess of the rotary ring 26, that is below or in front of the plane of the rotary ring.
  • the hook engagement of the lugs 36 via the pins 37 is such that the lamp housing 10 can only be lifted off the pins 37 in the maximum pivoting state according to FIG. 4. If the luminaire housing is pivoted less strongly, it is not possible to detach the lugs 36 from the pins 37.
  • the lamp housing is thus connected to the rotary ring 26 along the pivot axis 35 by a simple hooking connection.
  • latching elements 40 in the form of parallel grooves are arranged on the outside at different heights.
  • a locking device 41 acts against the outside of the side wall 10e and has two upstanding spring arms 42 supported on the rotating ring 26 and a pressing element 43 in the form of a roller on each spring arm.
  • the pressing elements 43 are pressed resiliently against the outside of the side wall 10e and thereby snap into the groove-shaped locking elements 40.
  • the part-cylindrical side wall 10e is curved around the pivot axis 35, so that the pressing force of the pressing elements 43 remains essentially the same regardless of the pivoting position of the lamp housing 10.
  • the gap 44 which is formed between the rotary ring 26 and the side wall 10e, remains the same width in each pivoting position of the lamp housing.
  • Fig. 4 shows the state of a ceiling spotlight, the radiation of which is directed to the bottom left. If the radiation is to be directed downward to the right, the pivoting position of the lamp housing 10 is maintained and the rotating ring 26 together with the lamp housing is rotated in the mounting ring 22 by 180 °. In this way, the radiation can be directed in any spatial direction within the angular range predetermined by the swivel range.
