Definitions

  • the invention relates to a luminaire, in particular an installation light emitter, for mounting in a recess, for example a ceiling, wall or the like, with a Werferor having a lamp, a reflector and a light exit opening, from which the light can escape in a light exit direction.
  • a luminaire of the type mentioned is often used as a built-in light emitter, also referred to as a spot used to achieve a high light approach a flush-mounted accentuation of near the ceiling erected objects or decorations, so-called Hochdeko.
  • Such lighting is desired, for example, for lighting in shop, in museums, at trade fairs or for lighting architecture.
  • a deflecting mirror is arranged, which deflects the light relative to the light exit direction in a Lichtumlenkraum.
  • a luminaire has the advantage that it is no longer necessary for the light exit opening to face the object to be illuminated, since the light can be deflected over the deflection mirror by a predetermined angle relative to the light exit direction onto the object.
  • the Werfertician compared to conventional recessed lights can be significantly further sunk in the ceiling cavity or wall cavity, so that at least the same functionality and the same efficiency over known lights a much smaller part of the lamp protrudes beyond the material surrounding the recess.
  • the throwing unit is mounted in the recess such that it does not protrude in the light exit direction beyond the material bounding the recess, for example the material of the ceiling, wall or the like, but instead is arranged entirely within the ceiling cavity.
  • the deflection mirror In order to reach each point of an object to be illuminated, be it so close to a ceiling, it can be provided that only the deflection mirror, at least partially, protrudes.
  • the luminaire, in particular the deflecting mirror protrudes a maximum of 30 to 80 mm, preferably a maximum of 55 mm, over the material delimiting the recess, for example the material of the ceiling, wall or the like.
  • the inventive lamp before a serving as a background, illuminated wall is hardly disturbing, since only a small part of the lamp is visible, and also the risk that a person unintentionally pushes the lamp, significantly reduced.
  • the latter in particular the deflecting mirror, is designed such that a light radiated from the thrower unit as a single image can be separated into individual partial images so that the partial images return to an object to be illuminated, for example a wall to be illuminated put together a single picture.
  • the mirror has several, in particular two to six, preferably four, segments.
  • the segments which may be spaced apart, are in particular formed as lamellae.
  • the light emitted by the throwing unit as a single image is split by the segmented deflection mirror into individual, for example four, partial images, which again adjoin one another on the object to be illuminated or the wall to be illuminated in such a way that a homogeneous light image, the is called a single image, created.
  • the overall height of the mirror is further reduced compared with a single, non-segmented deflecting mirror, so that such a lamp protrudes even less over the region of the recess.
  • the surfaces of the segments directed toward the lamp which are preferably arranged parallel to one another and in particular are planar, have different sizes.
  • the surfaces of the segments may have a different width and / or a different length, wherein in particular the width and / or length of the segment surfaces decreases with increasing distance of the segment surface from the light exit opening. In other words, the closer a segment surface is arranged to the light exit opening, the wider and / or longer the segment surface may be.
  • the surfaces of the segments directed towards the lamp are set relative to the light exit opening, in particular by an angle ⁇ of 30 ° to 60 °, preferably 45 °.
  • the surfaces of the segments directed toward the lamp do not overlap one another in the light exit direction and / or light deflection direction.
  • the deflecting mirror is fastened to the throwing unit in accordance with a further embodiment of the luminaire according to the invention.
  • the attachment is preferably detachable, so that the deflection mirror can be easily removed from the Werferü, so that the inventive lamp for certain lighting purposes can be used without the deflection mirror.
  • this has a mounting frame for fastening in the recess.
  • the Werferü and / or the deflection mirror can be movably mounted.
  • the throwing unit in particular together with the deflecting mirror, according to a further embodiment of the luminaire according to the invention relative to the recess by an angle ⁇ of a maximum of 40 ° to 80 °, preferably at most 60 °, pivotable.
  • the pivotability is achieved by a storage of the throwing unit, in particular together with the deflection mirror, in the mounting frame.
  • the throwing unit in particular together with the deflection mirror, is rotatable about an axis which runs perpendicular to the recess. Also in this case, the rotatability is achieved in a particularly simple manner by mounting the throwing unit, in particular together with the deflecting mirror, in the mounting frame.
  • the lamp 1 shows an embodiment of a lamp 1 according to the present invention in the form of a built-in light emitter.
  • the lamp has a Werferiser 2 with a lamp 3, a reflector 4 and a light exit opening 5, on which the light can escape in a light exit direction, on.
  • a deflecting mirror 6 is arranged in the light exit direction, which deflects the light relative to the light exit direction in a Lichtumlenkraum.
  • the mirror 6 has four separate segments 7a to 7d designed as lamellae, each having a surface (not shown in FIG. 1) directed towards the lamp.
  • the segments 7a to 7d are detachably held by a housing part 8, which is part of the throwing unit 2.
  • the lamp 1 also has a mounting frame 9, with which the lamp 1 can be mounted in a recess of a ceiling, wall or the like.
  • the Werfermati 2 is movably mounted together with the deflection mirror 6, namely both pivotally relative to the mounting frame 9 and thus to the ceiling recess, as well as rotatable about an axis about which the mounting frame 9 shown is rotationally symmetrical and perpendicular to the ceiling recess ,
  • the functional principle of the luminaire 1 according to the invention becomes clear with reference to the sectional view shown in FIG. From the throwing unit 2, which has the lamp 3, the reflector 4 and the light exit opening 5, light is arranged in the light exit direction on the outside of the throwing unit 2 , segmented Deflection mirror 6 thrown by the light relative to the light exit direction in a Lichtumlenkides, in the illustrated case by about 90 °, is deflected.
  • the individual segments 7a to 7d of the deflecting mirror 6 each have a surface directed towards the lamp 3, which causes the deflection of the light.
  • the surfaces of the segments 7a to 7d directed toward the lamp 3 are arranged parallel and flat, so that the light emitted initially as a single image is split into four partial images, which after deflection in the light deflection direction on the object to be illuminated or the wall to be illuminated be merged back into a single image and thus a homogeneous light image.
  • the lamps 3 are directed towards the surfaces of the segments 7a to 7d relative to the light exit opening 5 by an angle ⁇ of about 45 ° employed. It can also be seen that the surfaces directed toward the lamp 3 of the segments 7a to 7d do not overlap one another in the light exit direction as well as in the light deflection direction. In addition, it can be seen that the width of the individual segment surfaces decreases with increasing distance of the respective segment surface from the light exit opening 5.
  • the throwing unit 2 to which the deflecting mirror 6 is fastened, is mounted on the left side in a curved guide 10, which is connected to a part 12b of the mounting frame 9, and on the right side via a hinge 11 connected to the opposite side of the part 12b of the mounting frame 9. In this way, it is possible to pivot the throwing unit 2 together with the deflection mirror 6 relative to the recess in the illustrated ceiling 13 by an angle of 40 °.
  • the mounting frame 9 In addition to pivoting the mounting frame 9 also allows a rotation of the throwing unit 2 together with the deflection mirror 6, namely an axis which is perpendicular to the recess in the ceiling 13 .
  • the mounting frame 9 is formed in two parts, with a part 12a are firmly connected to the ceiling 13 can, whereas the part 12b is rotatably mounted in the part 12a of the mounting frame 9 . Since the throwing unit 2 is connected only to the part 12b of the mounting frame 9 and this is rotatable relative to the part 12a , the entire lamp 1 can be rotated in almost any position.
  • FIG. 2 also shows the attachment of the deflecting mirror 6 to the throwing unit 2 or the housing part 8.
  • the deflection mirror 6 is connected to the housing part 8 via a latching connection 14, which consists of a projection provided on the deflection 6 and a cooperating, provided on the housing part 8 recess.
  • the part of the deflection mirror 6 on which the projection is formed is so elastic that the projection can be bent back so far that it comes out of engagement with the depression, thereby releasing the deflection mirror 6 from the throwing unit 2.
  • FIG. 3 shows the luminaire 1 according to the invention with deflecting mirror 6 detached from the throwing unit 2.
  • the luminaire 1 can also be used to illuminate objects which are arranged below the luminaire 1.
  • the object to be illuminated is irradiated directly by the light emerging from the light exit opening, without a deflection occurring.
