Description

The present invention relates to a recessed luminaire for installation in a wall, in particular in the wall of a ceiling, a room wall or a floor, with a mounting frame which is insertable into an opening of the wall from the front thereof and defines a longitudinal axis of the recessed luminaire, and a Luminaire body which is pivotally supported on the mounting frame via a hinge about a transverse axis extending transversely to the longitudinal axis in a pivot plane and defines a light exit opening on its front side.

Recessed luminaires, which are particularly suitable for installation in a suspended ceiling, come in different configurations in the prior art. They generally comprise a mounting frame, which is designed such that it can be used in particular fit exactly into a provided for the recessed light opening in a wall, in particular a suspended ceiling. The mounting frame has for positioning in the opening usually a stop surface, which comes to rest on the facing the room front of the ceiling. Furthermore, fastening means, such as terminals, provided on the mounting frame, by which this is fixed in the opening. Such recessed lights also include a lamp body with a light source therein, which is held on the mounting frame. If the recessed luminaire is provided in the opening of the suspended ceiling, a cone-shaped area is usually illuminated beneath the recessed luminaire. The longitudinal axis of this light cone is aligned perpendicular to the ceiling.

In order to achieve greater flexibility with regard to the illuminated by the recessed luminaire room area, it is known to pivotally connect the lamp body about a hinge about a hinge axis with the mounting frame. Thus, the lamp body can be rotated about the hinge axis, for example, to illuminate a hanging on a room wall image by means of the recessed light. In particular, in the case of luminaire bodies which have a cylindrical or substantially cylindrical shape, the opening of the wall into which the recessed luminaire is inserted must be correspondingly large. Only then can it be avoided that a rear portion of the lamp body abuts against the edge of the opening during its pivoting movement in a fully swung-out position.

To counteract this problem, recessed luminaires are proposed in the prior art, in which the lamp body has a circular front with a light exit opening and the lamp body is hemispherical completed on the back, so that it tapers along the longitudinal axis of the luminaire in the direction of its back. Here, the center of the hemisphere is on or near the hinge axis of the joint. By this hemispherical configuration of a rear portion of the lamp body prevents the lamp body abuts during its rotational movement about the hinge axis against the edge of the opening of the wall. There are also known recessed lights whose cross-section is arcuate. The swing angle of the lamp corresponds to the circle segment, which is formed by the lamp. As a result, the required passage opening is always identical. At such recessed lights is considered disadvantageous, however, that the change in shape of the recessed luminaire, in particular, when the lamp body is in a significantly opposite the Normanstellung pivoted position, is clearly visible. The visual appearance of such recessed lights is often perceived as less appealing.

Against this background, the present invention seeks to provide a recessed luminaire of the type mentioned, which has an alternative structure. Such recessed luminaire should remain after installation in an opening of a wall in any position only a minimal visible gap between its lamp body and the edge of the opening of the wall and at the same time when moving the lamp body from the rear retracted position to the front extended position no visible change in shape exhibit.

To achieve this object, the present invention provides a recessed luminaire of the type mentioned above, which is characterized in that the lamp body is pivotally connected at its rear end portion with the mounting frame and relative to the mounting frame between a rear retracted position and a front extended position is held so movable in that, during adjustment, the joint axis of the joint is moved via guide means along a defined arcuate guideway and the luminaire body is pivoted about the articulated axis by a defined angle α, and the luminaire body is guided parallel to its central longitudinal axis and transversely, in particular perpendicular, to the pivot plane extending parting plane is divided into two side sections, wherein the cross section of the lamp body is perpendicular to its longitudinal axis in the one side section over the entire length of the lamp body constant or substantially is constant and the cross-section in the other side portion in at least a longitudinal section between the front and the back End face of the lamp body in particular steadily reduced, so that the lamp body forms in this side portion facing the dividing plane indentation which is in the front extended position at least partially opposite the front of a wall of the adjacent wall portion, in particular at a distance.

The solution according to the invention is thus characterized in particular by comparison with the recessed luminaires known in the prior art, that the lamp body is not only pivotally connected to the mounting frame, but is additionally adjustable along a curved path between a rear and a front position. Thus, there is a superposition of a rotation with an arcuate translational movement of the lamp body relative to the mounting frame instead. In addition, a recess in only one side portion of the lamp body is provided to realize a minimally visible gap between the lamp body and the edge of the opening of the wall without a visible change in shape upon adjustment of the lamp body.

The inventively embodied lamp body is connected at its rear end portion via the joint with the mounting frame. If the recessed luminaire is installed, for example, in a suspended ceiling of a room, the guide means and the hinge are located in a cavity on the back of the wall and are therefore neither in the rear retracted position nor in the front for a viewer looking at the front of the wall extended position of the lamp body visible. In conjunction with the superposition of a translational movement of the hinge axis of the joint of the lamp body along the arcuate track with a rotational movement of the lamp body about its hinge axis, is also allowed during the adjustment of the lamp body, that in the front extended position the largest possible part of the lamp body is located in the front room of the wall. On the other hand, a minimum visible gap between one side of the lamp body and the edge of the opening of the wall can be achieved.

In order to provide the necessary space for the pivoting movement of the lamp body, a recess is formed in a side portion thereof. This makes it possible that the lamp body with its indentation in its front, extended position at least partially opposite to the front of the wall portion adjacent to the opening of the wall. Thus, the orientation of an emerging from the light exit opening of the lamp body light cone can be changed without a part of the light cone shines into the opening of the wall and is cut off. In the prior art, however, when swinging out a side portion of a lamp body from an opening of a wall of the other side portion of the lamp body is pivoted in accordance with the opening of the wall. For an observer, the hemispherical back area of the lamp body becomes visible. When inventively designed luminaire body whose cross section is perpendicular to its longitudinal axis in the side portion which is opposite to the recess having side portion, over the entire length of the lamp body is substantially constant. For example, in the case of a cylindrical luminaire body, this cross section is constantly semiconical. Thus, there is no visible change in shape when moving the lamp body from the rear retracted position to the front extended position. Thus, for example, remains a cylindrical lamp body during its movement out of the opening of the wall apparently cylindrical, although it tapers in its recess having side portion in the direction of its rear end face. Thus, the visible area of the lamp body have the desired shape by the designer.

According to one embodiment of the invention, the measured between the longitudinal axis of the downlight and the longitudinal axis of the lamp body pivot angle α between 30 ° and 60 °, in particular between 40 ° and 50 °, and preferably at 45 °. As a result, a maximum number of adjustable illumination directions is ensured with a built-in luminaire once installed in an opening of a wall. At the same time it is ensured for aesthetic reasons that the rear end face of the lamp body does not protrude or only to a small extent from the opening of the wall out in the front space of the wall.

Preferably, the lamp body is connected at its rear end face via the hinge pivotally connected to the mounting frame. In particular, the joint is provided centrally on the rear end face, so that the hinge axis and the longitudinal axis of the lamp body cross each other. This makes it possible that in the front extended position as large a part of the lamp body is located in the frontal space of the wall. Advantageously, the hinge comprises a hinge pin, which is mounted on two parallel projections, which are provided on the rear end face of the lamp body. A bearing on two parallel projections is advantageous because the hinge pin is thereby stored very stable and can not tilt sideways. However, the hinge pin can also be mounted only on a provided on the rear end face of the lamp body projection. In an alternative embodiment, the hinge pin is divided into two, wherein the two hinge pin sections are mounted on two opposite sides of the rear end portion of the lamp body to form a common hinge axis on the lamp body.

According to a further embodiment of the invention, the guide means are designed in the form of a slotted guide. Preferably, two parallel arcuate scenes are provided to form the slide guide in the mounting frame, in which the hinge pin and is guided. Alternatively, the two scenes can also be provided on two opposite sides of the lamp body. In this case, the hinge pin is mounted on the mounting frame. The engagement of the hinge pin in two parallel scenes a stable guidance of the hinge pin and thus the lamp body is guaranteed. Through the scenes, the arcuate guideway and thus the translational movement is clearly defined. For example, the arcuate gate can have the shape of an arcuate slot with semi-circular ends. Advantageously, the hinge pin is held in the scenes self-locking or locking means, in particular clamping means fixed. This offers the advantage that the adjustable between the rear retracted position and the front extended position lamp body can easily persist in any intermediate position.

The recessed luminaire preferably comprises a guide device in order to guide the side section of the luminaire body having the recess when the luminaire body is adjusted. Advantageously, the guide device comprises two guide arms, wherein one end of a guide arm in the region of the recess is fixedly connected to the lamp body, one end of the other guide arm is rotatably connected to the mounting frame and the free ends of the two guide arms are also rotatably connected to each other, said Rotary axes of the guide arms extend parallel to the hinge axis of the joint. Conveniently, the lengths of the guide arms are chosen so that in this way the distance is predetermined, in which the indentation of the lamp body in the front extended position at least partially opposite the front of the adjacent to the opening of the wall wall portion. The guide arm connected to the lamp body is in this case connected in particular to half the length of the lamp body with this. This allows optimal guidance and support of the lamp body. Alternatively, the guide device may be designed in the form of a slide guide.

Advantageously, the recessed light, in particular by the guide means and the guide means, designed so that the distance between the side of the lamp body, which lies opposite the recess, and the edge of the opening during the adjustment of the lamp body remains substantially constant. This is advantageous because for a viewer both in the rear retracted position and in the front extended position of the lamp body, a consistently narrow gap between the side of the lamp body and the edge of the opening is visible. Thus, this contributes to the fact that for a viewer, the overall appearance of the recessed light hardly changes after an adjustment of the lamp body in the sense of the designer.

According to a further embodiment of the invention, the cross section of the lamp body is constant perpendicular to its longitudinal axis in its side portion having the indentation over a front longitudinal section, steadily decreases in an adjoining central longitudinal section and is constant again in a rearward longitudinal section adjoining the central longitudinal section. The constant in the front longitudinal section cross-section has the advantage that the lamp body, especially when viewed in its rear retracted position, for the viewer has a seemingly uniform basic geometric shape. For example, the viewer has the impression that it is is a completely ylindrischen lamp body, although this tapers towards its rear end face. In addition, this provides enough space for the arrangement of bulbs, reflectors and other elements inside the lamp body. The constant cross section in the rearward longitudinal section is also advantageous since it can be easily realized during manufacture of the luminaire body.

Preferably, the indentation, starting from the rear end face of the lamp body, extends over at least 50%, at least 60%, at least 70%, preferably at least 80%, or even more preferably at least 85% of the length of the lamp body. It is advantageous if the indentation extends over a large part of the length of the lamp body. This makes it possible that protrudes in the rear retracted position, only a small length portion of the lamp body from the opening of the wall out in the frontal space of the wall, while in the front extended position, a majority of the lamp body is located in the front space of the wall. Because often - is desired - especially for aesthetic reasons - that in the rear retracted position, a majority of the lamp body is located in the rear space of the wall.

Appropriately, the measured perpendicular to the separation plane width of the lamp body in the indentation by at least 30%, in particular at least 40% and the indentation extends maximally to the longitudinal axis of the lamp body. Such a depth of the recess is advantageous because on the one hand, the visible gap between one side of the lamp body and the edge of the opening of the wall can be kept small and on the other hand enough space for the arrangement of bulbs, reflectors and other elements within the lamp body is kept ,

According to a further embodiment of the invention, the indentation has at least one perpendicular or substantially perpendicular to the pivot plane surface. By substantially perpendicular is meant that a majority, in particular at least 80%, of the surface is perpendicular to the pivot plane. For example, the edge regions of the surface may be slightly beveled, so that these edge regions are no longer perpendicular to the pivot plane, although they are part of the surface. The indentation is preferably formed by two flat or substantially planar surfaces running perpendicular or substantially perpendicular to the pivoting plane and intersecting at an angle β, which in particular arcuately merge into one another, wherein β - 90 ° preferably corresponds to the maximum pivoting angle α. A substantially planar surface is to be understood as meaning a surface which for the most part consists of a plane but has edge regions which are slightly beveled with respect to the plane. Such a substantially flat surface is also only substantially perpendicular to the pivot plane. Such flat surfaces are easy to realize in terms of manufacturing technology. In particular, the recess is formed starting from the rear end face of the lamp body by a substantially parallel to the parting plane extending surface and an adjoining at an angle β to the parting plane inclined surface, the inclined surface in the front extended position of the lamp body of the front to opposite to the opening of the wall adjacent Wandungsabschnitts and is aligned parallel thereto. For an optimal parallel alignment, it is therefore advantageous if the intersection angle of the two flat surfaces corresponds to the maximum pivot angle α. Advantageously, the surface extending substantially parallel to the parting plane extends over 35-45% and the surface inclined at an angle β to the parting plane extends over 25-35% of the length of the lamp body. This will ensure that inside the luminaire body sufficient space for the arrangement of bulbs, reflectors and other elements is available. In addition, a sufficient depth of the indentation is ensured over the longitudinal extent of the inclined surface at an angle β to the parting plane.

In an alternative embodiment, the indentation is formed by an arcuate surface extending perpendicularly or substantially perpendicularly to the pivoting plane and is designed such that in the front extended position of the luminaire body a tangent of the arcuate surface is parallel to the front side of the wall portion adjacent to the opening of the wall is aligned. For the meaning of substantially perpendicular reference is made to the above statements. Such a configuration of the indentation is advantageous because the cross section of the lamp body is continuously reduced in the side portion having the indentation up to the rear end face. Alternatively, the indentation, starting from the rear end face of the luminaire body, can initially also run in an arc shape parallel to the parting plane and thereafter.

Preferably, the lamp body is rotatably mounted in the mounting frame about the longitudinal axis of the luminaire. Such a rotation of the lamp body allows a variation of the pivoting plane, which is why it is possible to perform the movement of the lamp body from the rear retracted position to the front extended position in different spatial directions. Thus, with a recessed luminaire mounted once in a wall of a ceiling, after a corresponding rotation of the luminaire body about the longitudinal axis of the recessed luminaire, for example, images arranged on different room walls can be illuminated. With the recessed luminaire described above, therefore, a recessed luminaire is provided for the first time that leaves only a minimal visible gap between its lamp body and the edge of the opening of the wall after installation in an opening of a wall and at the same time when moving the lamp body from the rear retracted position in the Front extended position has no visible change in shape.

FIG. 4

a schematic view of an alternative designed lamp body for a recessed luminaire according to the present invention.

The FIGS. 1 to 3 show schematic views of a recessed light 1 according to an embodiment of the present invention. The recessed luminaire 1 comprises a mounting frame 2, which in an opening 3 of a wall 4, for example, a suspended ceiling, is used from the front side 5 ago, so that a stop surface 6 of the mounting frame 2, the front side 5 of the wall 4 contacted, and defines a longitudinal axis L of the recessed luminaire 1. Furthermore, the recessed luminaire 1 comprises a lamp body 8, which is connected to the mounting frame 2 and with respect to this is pivotable and displaceable. The arrangement is such that during the adjustment of the lamp body 8 from a rear retracted position, see FIG. 1 , in a front extended position, see FIG. 3 , the lamp body 8 performs a superimposed with an arcuate translational movement rotational movement relative to the mounting frame 2.

To achieve this, a joint 10 is provided on the rear end portion 9 of the lamp body 8, which comprises a hinge pin 11. More specifically, at a central location of the rear end surface 12 of the rear end portion 9 of the lamp body 8, two parallel projections 13 are provided on which the hinge pin 11 is supported. In the front views of the FIGS. 1 to 3 only one of the two projections 13 can be seen. Here, the transverse to the longitudinal axis L of the recessed luminaire 1 extending hinge axis and the longitudinal axis X of the lamp body cross 8. In the mounting frame 2, two parallel arcuate scenes 7 are provided, in which the hinge pin 11 of the lamp body 8 is guided. In the front views of the FIGS. 1 to 3 is only one of the two scenes 7 recognizable. The lamp body 8 is thus held about the hinge axis in a plane parallel to the plane of the figures pivot plane pivotally mounted on the mounting frame 2 and against this so between the rear retracted position and the front extended position that during an adjustment of the lamp body 8 of the hinge pin 11 on the moved two scenes 7 along a defined arcuate track and the lamp body 8 to a defined Angle α is pivoted about the hinge axis. The angle α is in this case measured between the longitudinal axis L of the recessed luminaire 1 and the longitudinal axis X of the lamp body 8 and is in the in FIGS. 1 to 3 illustrated embodiment about 35 °. The hinge pin 11 may in this case be held self-locking in the scenes 7 or is about locking means, in particular clamping means fixable.

In addition, in this exemplary embodiment, the luminaire body 8 is subdivided into two side sections 14, 15 by a dividing plane which extends over the central longitudinal axis X and extends perpendicular to the pivot plane. The cross section of the lamp body 8 perpendicular to its longitudinal axis X is substantially constant in the one side section 14 over the entire length of the lamp body 8. The cross section is only substantially constant, since the light exit opening of the lamp body 8 protrudes slightly from its front side. In the other side portion 15, the cross section decreases continuously in a length portion between the front side and the rear end surface 12 of the lamp body 8. More specifically, the cross-section is initially constant over a front-side length portion that extends from about the front of the lamp body 8 over about 26% of the length of the lamp body 8. In a subsequent to the front-side longitudinal section longitudinal length portion which extends over about 32% of the length of the lamp body 8, the cross-section decreases steadily. In an adjoining the middle longitudinal section rear side portion which extends over the remaining about 42% of the length of the lamp body 8, the cross section is again constant. In this way, in this side portion 15 of the lamp body 8 a pointing to the dividing plane indentation 16 is formed, which is defined by two perpendicular to the pivot plane and at an angle β intersecting flat surfaces 17, 18, wherein β - 90 ° the maximum tilt angle α equivalent. Thus, the geometric corresponds Design of the indentation 16 directly with the maximum swivel angle. More precisely, the indentation 16, starting from the rear end face 12 of the lamp body 8, is formed by a surface 17 running essentially parallel to the parting plane and an adjoining surface 18 inclined at an angle β to the parting plane. In this case, the indentation, starting from the rear end face 12, extends over approximately 75% of the length of the lamp body 8. The width of the lamp body 8 measured perpendicular to the parting line is reduced by approximately 47% in the region of the indentation 16. The indentation 16 does not extend completely to the longitudinal axis X of the lamp body.

The recessed light 1 further comprises a guide device 20 with two guide arms 21, 22. Here, one end of a guide arm 22 in the region of the recess 16 halfway along the lamp body 8 is fixedly connected to this 8, one end of the other guide arm 21 with the Mounting frame 2 rotatably connected and the free ends of the two guide arms 21, 22 are also rotatably connected to each other. The axes of rotation of the guide arms 21, 22 extend parallel to the hinge axis of the hinge pin 11. By the guide means 20 of the indentation 16 having side portion 15 of the lamp body 8 is guided during adjustment of the lamp body 8 such that the inclined surface 17 of the recess 16 in the Front extended position partially opposite the front of a to the opening 3 of the wall 4 adjacent wall portion 23 at a distance and is aligned parallel thereto. In this case, the distance can be specified by the selected length of the guide arms 21, 22.

By the previously described slide guide, in which the hinge pin 11 is guided in the two parallel arcuate scenes 7, and the guide device 20 described above is achieved that the distance d between the side of the lamp body 8, which is opposite to the recess 16, and the edge of the opening 3 during the adjustment of the lamp body 8 remains substantially constant.

The FIG. 4 shows a schematic view of an alternative designed lamp body 8 for a recessed light 1 according to the present invention. For clarity, both the mounting frame 2 and the guide device 20 are not in the FIG. 4 shown. Also, the hinge 10 of the lamp body 8 is not shown for the reasons mentioned above. With regard to possible embodiments for in the FIG. 4 not shown elements of the recessed luminaire 1 is particularly to the above statements to the FIGS. 1 to 3 directed. The lamp body 8 off FIG. 4 is different from the one from the FIGS. 1 to 3 in that the indentation 16 of the lamp body 8 is formed by a single arcuate surface 24 extending perpendicular to the pivoting plane. The indentation here extends over approximately 75% of the length of the luminaire body 8, starting from the rear end face 12. Such a configuration is advantageous, since in this way the cross section of the luminaire body 8 in the side section 15 having the indentation 16 extends continuously as far as the rear end face 12 of the lamp body 8 is reduced. In the FIG. 4 various positions of the lamp body 8 are shown during its displacement within an opening 3 of a wall 4, namely a rear retracted position, a front extended position and two positions in which the lamp body 8 is between the rear retracted position and the front extended position. This superimposed positional representations of the lamp body 8 illustrate once again that it comes with the recessed luminaire 1 according to the invention with an adjustment of the lamp body 8 relative to the mounting frame 2 to a superposition of a rotational and an arcuate translational motion. Due to the special design of the lamp body 8, in the front extended position, a tangent of the arcuate surface 23 is aligned parallel to the front side of the wall portion 22 adjacent to the opening 3 of the wall 4.

Although the invention has been further illustrated and described in detail by the preferred embodiment, the invention is not limited by the disclosed examples, and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention.
