    SWIVELED DOWNLIGHT
    The present invention relates to a downlight, in particular a downlight, which can be installed in a ceiling cutout. Downlights are to be understood as emitters that are intended to emit light downwards from a ceiling.
    For downlights of the type mentioned, it is often desirable to be able to influence the light output of the downlight by adjusting the downlight. For example, downlights located near a wall are directed toward the wall to achieve special lighting effects on the wall. Also for other applications, e.g. When illuminating an object in the room or on the wall, it is desirable to be able to adjust the downlights in one direction after installation.
    Such an adjustment of the light output can be achieved for example by moving a reflector within the downlight, as described in US 4,775,174 A.
    Another way to adjust a downlight is that a light insert of the downlight is guided on an axis in a frame of the downlight, so that the downlight is pivotable about the axis. Here, however, a relatively complicated mechanism is often necessary to determine the downlight in the pivoted position. For example, WO 2007/120792 A1 describes an adjustable downlight which has a plurality of toothed wheels which interact with a toothed rail on a lamp insert in order to realize the lockable adjusting mechanism.
    Object of the present invention is to provide a downlight available, which has a pivoting mechanism, which is structurally simple form and yet is also suitable for heavy lights.
    The object is achieved by a downlight according to claim 1.
    To realize a pivoting mechanism between the lamp insert and the mounting frame is omitted according to the present invention to a conventional bearing with an axis. Instead, four arcuate guide slots are provided, in which the lamp insert with bolts, preferably bolts made of plastic or plastic coating, engages. By moving the bolts along the guide slots pivotal movement of the lamp insert can be performed. The guide slots may, in one embodiment, describe a circular arc. Then the pivoting movement of the lamp insert leads to a movement which would correspond to a rotation about an axis without such an axis being physically present. However, it is even possible to make the guide slots not circular arc. In this way, pivoting movements for the luminaire insert can be realized, which would not be possible at all by a simple axis.
    According to a preferred embodiment, a reflector of the lamp insert is viewed in the direction of the light source to the light exit surface of the lamp at least partially disposed in front of the light source and moves during pivoting of the light insert with this. The reflector concentrates the light of the luminous means in a preferred direction, in particular along the optical axis. The resulting cone of light is suitable for adjustable downlights, because it allows the illumination of certain objects in the room in the manner of a spotlight. There are also wide-radiating downlights by a correspondingly shaped reflector possible. Furthermore, asymmetrical light distributions are possible, which are produced by an adapted form of the reflector.
    Since the reflector is mounted according to the invention on the light insert, the light distribution is adjusted by the pivoting of the luminaire insert in the room. The reflector may e.g. be integrally formed with the lamp.
    According to a preferred embodiment, the lamp insert is pivotable between a position of 0 ° to 40 °, wherein in the position at 0 °, the optical axis of the reflector is oriented perpendicular to a defined by the mounting frame light exit opening. This corresponds with the built-in downlight of the vertical direction. Accordingly, in the pivoted position, the optical axis is inclined relative to the vertical in space.
    Although considered according to some embodiments, it is not mandatory to have to deflect the lamp insert in two directions each in the maximum pivoting movement, because according to the invention can also be provided that the lamp is rotatable about the vertical axis by 360 °. Therefore, pivoting from 0 ° in one direction to the maximum pivotal position of e.g. 40 °.
    According to one embodiment with a lamp arranged in front of the reflector is in the pivot position of 0 °, the lower edge of the reflector relative to the light exit opening, which is defined by the mounting frame, set back. Preferably, the reflector is set back from the light exit surface so far that in the maximum pivoting position, e.g. 40 °, the bottom edge of the reflector is flush with the exit surface. In this way it is prevented that the downlight protrudes with a reflector from a ceiling cutout, in which the downlight is mounted, in a pivoting position. For example, the reflector in the 0 ° position by up to 20 or 40 mm behind the light exit opening of the mounting frame, which corresponds in the installed state of the lamp about the plane of the ceiling installation, be set back.
    According to a preferred embodiment, a wave structure is provided in at least one of the four guide slots, preferably on two guide slots on the two opposite wall sections, on the edge facing the light exit surface, on which the respective bolts of the guide slots in the idle state of the down lights rest. Due to the weight of the light insert, the bolts are located at the bottom. The wave structure prevents the luminaire insert from shifting unintentionally. To adjust the light of the lamp insert is slightly raised so that the bolts on the opposite smooth edge of the guide slots for pivoting the corpse insert can slide along. After lowering the lamp insert, the bolts rest on the shaft structure, so that the desired pivot position is fixed.
    According to a preferred embodiment, the two wall portions of the mounting frame, in which the guide slots are provided, part of a U-shaped bent bracket. The bracket is preferably made of a metal sheet. Such stirrups can be easily produced as a bending stamped part and moreover has the advantage that the legs of the stirrup can also be bent in such a way that they define a prestressing in the direction of the luminous insert between the legs. For example, the legs of the sheet holder can run at an angle of 10 to 5 ° to each other when no lamp insert is mounted in the bracket. When mounted luminaire insert the brackets are bent back parallel to each other, whereby a force is exerted on the luminaire insert. This force supports the frictional force between the stirrup legs and the luminaire insert, so that, apart from the previously described wave structure at the edges of the guide slots, the pivoting position of the luminaire insert is further stabilized.
    According to a preferred embodiment, the mounting frame is adapted for installation in a ceiling opening, wherein the two wall sections are aligned perpendicular to the ceiling. In this embodiment, it is further preferred that the downlight is opposite the ceiling cutout about its vertical axis, i. an axis perpendicular to the ceiling, is rotatable. The pivot axis of the lamp, which is generally parallel to the ceiling installation, can be adjusted in this way in the room in any direction parallel to the ceiling.
    A preferred embodiment of the present invention will be described below in conjunction with the accompanying drawings. The figures show the following: FIGS. 1 and 2 show a perspective view of a downlight in one
    Pivoting position of 0 ° resp. 40 °.
    Figures 3 and 4 show a horizontal section through the lamp according to Figure 1 and Figure 2.
    FIG. 5 shows a section according to FIG. 4, but in an image plane of FIG
    FIG. 4 offset the cutting plane.
    FIG. 6 shows a side view of the downlight.
    Referring to Figures 1 and 2, a perspective view of an embodiment of the downlight is shown. The downlight comprises a luminaire insert 2 and a mounting ring 4, in which the luminaire insert 2 is mounted. The mounting ring 4 rests on a Einlegering 6 and is supported with holding elements 8 on this.
    In the following, the attachment of the lamp insert 2 in the mounting ring 4 will be described in more detail.
    The luminaire mounting ring 4 has a retaining clip 10, which is formed from a U-shaped bent sheet metal element. The legs of the U-shaped bracket 10 define two wall sections 12 between which the lamp insert 2 is attached.
    The wall sections 12 each have a mirror-symmetrical two guide slots. A guide slot 14 is made smooth and another pair of guide slots 16 is formed with a wave structure on the light emitting surface of the lamp facing edge.
    The luminaire insert 2 has a total of four plastic bolts 18, which engage in a respective guide slot 14 and 16 respectively. The plastic bolt 18 are slidable along the guide slots 14 and 16 respectively. By an arcuate shape of all guide slots 14 and 16, the lamp insert 2 can be pivoted relative to the mounting frame 4. Figures 1 and 2 show the maximum pivot positions. In Figure 1, the bolts 18 abut at one end of the guide slots 14 and 16, respectively. The longitudinal axis of the lamp insert 2 is perpendicular to the light exit opening of the lamp. This position is referred to as 0 ° position. In FIG. 2, the bolts 18 abut against the opposite ends of the guide slots 14 and 16, respectively. In this position, the longitudinal axis of the lamp insert 2 is inclined relative to the light exit surface by 40 °. That pivot position is referred to as a 40 ° swivel position.
    In the figures 3 and 4, which show the corresponding pivoting positions as in Figures 1 and 2, the lamp is shown in a section. Furthermore, an intermediate ceiling 20 is shown in these figures also in section, in which the lamp is installed. It can be seen that in the 0 ° swivel position, the optical axis of the lamp insert is perpendicular to the surface of the ceiling 20, while in Figure 4, the optical axis of the lamp insert 2 is inclined by 40 ° relative to the surface of the ceiling 20.
    In the guide slots 16, a wave structure is formed on the pointing to the light exit surface edge of the guide slot. The radii of the wave structure are approximately matched to the diameter of the pin 18 which runs in the guide slot 16. In the resting state of the lamp, the bolts 18 rest on the shaft structure and are thereby prevented from slipping. Thus, the pivot position of the lamp is secured in the situation. To adjust the light of the lamp insert 2 is raised slightly against gravity, so that the bolts 18 abut the top edge of the guide slots 14 and 16 respectively. As a result, the bolts 18 are no longer in contact with the shaft structure and can be moved along the guide slots. In this way, the lamp can be moved between two different pivot positions.
    The luminaire insert has a reflector 22 (not shown in Figures 1 and 2 for simplicity of illustration, but in Figures 3, 4 and 5 to see). The reflector surrounds a luminous means (not shown in the figures) and defines an optical axis of the luminaire insert 2. As can be seen in FIGS. 3 and 4, in the 0 ° pivot position the lower edge of the reflector is set back relative to the light exit surface. The distance is dimensioned so that in the maximum pivoting position, as shown in Figure 4, the lowest edge portion of the reflector 22 approximately flush with the light exit surface of the lamp. Thus, the downlight is in the installed state, regardless of which pivot position, never beyond the ceiling opening.
    The mounting frame 4 is based in the installed state on a Einlegering 6, which is placed on the false ceiling 20. However, the connection is not rigid. The mounting frame 4 can slide over the insert ring 6 to rotate the lamp about the vertical axis. Due to the rotation about the vertical axis of 360 ° in conjunction with the azimuthal adjustment by the pivoting movement, which can be performed from 0 ° to the maximum pivot position, it is possible to adjust the optical axis of the luminaire insert over a wide angular range in space.
    Numerous modifications to the preferred embodiments presented above are possible within the scope of the invention, which is defined by the following claims. In particular, more than just four guide slots can be provided. Furthermore, the guide slots do not necessarily have to be exactly circular-arc-shaped, and it is also taken into account, for example, to form the guide slots along a special curve so that the distance between the reflector lower edge and the light exit surface in the 0 ° position (see FIG. 3) is reduced can be without protruding beyond the light exit surface in the maximum pivotal position of the edge of the reflector (see Figure 4).
