Abstract

A built-in spotlight has a holder for fastening it to a mounting surface, in particular the ceiling of a room, and a lamp socket mounted in a rotary or swivelling manner in a housing closed in the direction of illumination by a transparent cover in an at least substantially dust-tight manner. In this built-in spotlight, the transparent cover is not coupled to the swivelling lamp socket, and therefore the transparent cover extends parallel to the mounting surface, in particular flush therewith, in every swivelling position of the lamp socket.

Description

Recessed Spotlights

The invention relates to a recessed spotlight with a holder for mounting in a mounting surface, in particular a ceiling, and a bulb holder, which is rotatably mounted and / or pivotally mounted in a housing which is at least substantially dust-tight in the illumination direction by means of a translucent cover. Due to the pivotable mounting of the lamp holder and possibly a reflector coupled thereto, the emission angle of the recessed spotlight can be adjusted in a desired manner.

Such a recessed spotlight with adjustable radiation angle is known for example from FIGS. 3 and 4 of the German patent application DE 10360947.4 of the applicant. With this radiator, it is possible to swivel out a reflector coupled to the light-emitting means holder in regions from the housing, wherein the reflector opening located in the illumination direction can be sealed in a dust-tight manner by means of a transparent pane.

In particular, in the swung-out position of the reflector, which is shown for example in Fig. 4 of said application, formed between the housing and the reflector, a gap which allows penetration of dust into the housing interior to a certain extent.

Furthermore, it is obvious that a plurality arranged in a mounting surface recessed spotlights of the type mentioned when viewed from below each offer a different appearance, if in the individual recessed spotlights different reflector tilt angle are set.

An object of the invention is to refine a recessed spotlight of the type mentioned in such a way that regardless of the respective adjusted beam angle or regardless of the respective pivot angle of the bulb socket a uniform appearance of the recessed spotlight is ensured, in particular a seal of the housing interior against the ingress of Dust should be achieved. Finally, the use of high-pressure halogen lamps in a recessed spotlight according to the invention should preferably also be made possible by ensuring protection against UV light and from falling fragments of a bursting lamp.

According to the invention at least the first object is achieved by the features of claim 1 and in particular by the fact that the translucent cover is decoupled from the pivotable bulb socket, so that the translucent cover in each pivot position of the bulb socket parallel and in particular flush with the mounting surface.

According to the invention, therefore, the translucent cover is coupled to the housing so that their position regardless of the respective given pivoting angle of the light source always remains unchanged, so that the appearance of the recessed spotlight according to the invention, which is characterized substantially by the position of the translucent cover, by pivoting the Bulb holder can not be changed significantly. Due to the decoupling according to the invention between the pivotable light-emitting means holder and the light-permeable cover, it is thus achieved that the light-permeable cover is imprinted. mer parallel to the mounting surface and, which is particularly preferred, flush with the mounting surface, so that the recessed light according to the invention at each pivot position of the lamp holder with a uniform appearance blends in harmoniously with the mounting surface.

In addition, the translucent cover can be formed in particular when using a high-pressure halogen lamp as a UV filter, in which case it also provides protection against falling fragments of a bursting high-pressure halogen lamp.

As a result of the fixed position of the translucent cover which is fixedly predetermined according to the invention and during operation of the recessed spotlight, the translucent cover can be coupled to the housing in a particularly effective dustproof manner. In accordance with the invention, a mechanically complex enabling of a relative movement between light-permeable cover and housing for setting different emission angles is not necessary. In this respect, the dustproofness of a recessed downlight compared to known recessed spotlights can be improved with swiveling bulb holder, as between see translucent cover and housing no additional acting on the bulb socket or a reflector pivot mechanism must be provided.

It is advantageous if the bulb holder is pivotable about two mutually perpendicular axes, since in this case virtually any tilt angle can be adjusted so as to create the respectively desired lighting situation can.

The light-emitting means can either be mounted alone or, which is preferred, together with a reflector, pivotably mounted in the housing. It is advantageous if the reflector and a preferably coupled with this filter disc are interchangeable stored in the housing so that in this way, for example, set different lighting characteristics and beam angle and / or different light colors can be generated. The use of UV and IR filters is also possible with provision of said filter disk. Alternatively or additionally, the light-permeable cover provided according to the invention can also be designed as a UV and IR filter.

For the power supply of the lamp holder can be provided between this and the housing bottom, a flexible cable which in certain embodiments, for example in such, as described below in connection with Figures 1 to 6, may have a plug connection. About such a connector, it is then possible to solve a complete, housed in the housing emitter unit with lamp holder, reflector, light sources and possibly other parts of the housing, which allows, for example, a convenient replacement of lamp or reflector.

It when the translucent cover is coupled with a Ausblendring, which in turn is decoupled from the pivotable lamp holder is particularly advantageous. The position of the Ausblendrings, which preferably extends substantially perpendicular to the plane of extension of the translucent cover, so as well as the position of the translucent cover regardless of the respectively set

Swivel angle of the bulb holder or the reflector. This allows in particular a firm coupling of Ausblendring and translucent cover. The diameter of the Ausblendrings can be dimensioned so that in each pivot position of the reflector, a distance between the reflector and Ausblendring is ensured. It is thus reliably avoided that at certain pivot positions of the reflector, a collision between reflector and Ausblendring occurs. To achieve this, the diameter of the Ausblendrings is usually sized slightly larger than the diameter of the reflector located in the illumination direction reflector opening. The height of the Ausblendrings can be dimensioned smaller than the reflector height and in particular can be less than 50% of the height of the reflector.

A particularly efficient effect of the Ausblendrings can be achieved if its inner side has a lower reflectivity than its outer side, the inside can in particular absorbent and the outside in particular reflective properties. Due to the low reflectivity or the absorbing properties of the inside of the Ausblendrings is effectively avoided that when viewing the recessed light according to the invention under an oblique viewing angle for the viewer a glare occurs. By contrast, the reflective properties of the outside of the masking ring can be used to direct a portion of the light generated by a luminous means into a region of the housing surrounding the reflector. This is particularly useful if a reflector opening located in the direction of illumination defines a direct light exit area which is surrounded at least in regions by a diffuse light exit area. The latter features are also realized in a spotlight according to the aforementioned German patent application DE 10360947.4 and cause that can be used in the direct light exit area with reflectors according to the known dark light principle using the associated advantages, but at the same time scattered light around the direct light exit region scattered light from the diffuse light exit region, which can be selected in the luminance so that no glare occurs. Thus, a visible marking of the light source is always guaranteed in this variant, which despite the use of the dark light principle leads to a perceived as pleasant room atmosphere with good light atmosphere. Further advantages and embodiments of direct light exit region and diffuse light exit region are explained in the aforementioned application DE 10360947.4.

In the above-mentioned realization of the Ausblendrings with reflective outer surface, among other things, on the reflectivity and the size of the planar extent of the outer side of the Ausblendrings the amount of that portion of light to be increased or adjusted, which ultimately lent to reach the Diffuslicht- exit region.

It is preferred if the direct light exit region and the diffuse light exit region can be acted upon by a common light source. The reflector opening defining the direct light exit region can be assigned to a direct light reflector, on whose side facing away from the direct light exit region an additional or background reflector is provided. In this case, the direct light reflector then also has a rear opening through which light can pass to the additional or background reflector, which is formed, for example, by the inside of the housing of the recessed spotlight according to the invention and / or by the outside of the direct light reflector.

A meaningful distribution of light between direct light exit area and diffuse light exit area can be achieved if an area of the illuminant within the direct light reflector and a Another area of the light source between the direct light reflector on the one hand and additional or background reflector or light source is on the other hand. Conventional lighting means consist for example of a clear glass bulb, in which the actual, light-generating element is arranged. It is advantageous if the light-generating element is located in the focal point of the direct light reflector and the glass bulb projects rearwardly out of the direct light reflector, so that this part of the glass bulb is located between direct light reflector on the one hand and additional or background reflector or light bulb socket on the other hand. Sufficient light then reaches the diffuse light exit area via this part of the glass bulb.

The translucent cover according to the invention running parallel to the installation plane can be made transparent in the direct light exit region and in the diffuse light exit region as a diffusing screen. In this case, it is possible to form the light-permeable cover in two parts, wherein a first part is formed by a transparent disc covering both the direct light exit region and the diffuse light exit region and sealing off the housing in a dust-tight manner, and the second part consists of a transparent pane launched, the direct light exit area surrounding lens diffuser exists. The shape of the diffuser then corresponds to the shape of the diffuse light exit region.

A particularly advantageous light effect arises when the blanking ring extends along the dividing line between the direct light exit region and the diffuse light exit region. In this case, the Ausblendring prevents direct irradiation of the diffuse light exit region by the lighting means, so as to ensure that only indirect and thus less intense light reaches the diffuse light exit region. It is particularly advantageous if a swiveling mechanism operable from the outside of the housing for pivoting the light-emitting means is provided in the housing. In this context, in particular in the area of the translucent cover, two adjusting screws provided for actuation of the pivoting mechanism can be arranged, which are accessible from the outside, each adjusting screw being responsible for pivoting the illuminant mount or the reflector about one axis. By enabling actuation of the pivoting mechanism from the outside, it is achieved that the recessed luminaire according to the invention only has to be opened when a change of lamp, reflector and / or filter is desired. For adjusting the pan or beam angle, however, no opening of the recessed spotlight is necessary.

In the latter variant according to the invention, the luminous means holder or the reflector can be mounted via a gimbal joint, whose two hinge axes are in operative connection with the adjusting screws via a flexible shaft. The gimbal joint can be pivotally mounted in particular in Ausblendring.

The maximum possible pivoting angle about both joint axes of the cardan joint can each be a maximum of +/- 45 ° and preferably approximately between +/- 30 ° and +/- 35 °. A corresponding limitation of the swivel angle can be achieved by means of a stop known from the prior art, which are provided in the region of the joint axes.

The light-permeable cover provided according to the invention can be made detachable or swing-away from the housing. In particular, closure mechanisms can be used here, as they For example, in the German patent applications DE 10360948.2 and DE 10 2004 048 484.8 of the applicant are described.

The diameter of the blanking ring connected to the translucent cover is preferably dimensioned such that when the translucent cover is released or pivoted away, a distance between reflector and blanking ring is ensured, whereby a collision between reflector and blanking ring is reliably avoided.

In a translucent cover that can be detached from the housing or pivoted away, it is not absolutely necessary that the pivoting mechanism according to the invention can be actuated from the outside of the housing. Rather, after a release or pivoting away of the translucent cover, the reflector or the illuminant holder can be grasped and brought into the desired pivot position, whereupon the translucent cover can then be closed again.

As an alternative to the gimbal joint already explained, the luminous means holder can also be pivotably mounted in a hinge bracket arrangement about an axis extending parallel to the translucent cover, wherein the hinge bracket arrangement itself can be rotatably mounted about an axis perpendicular to the translucent cover. In this case, the maximum possible pivoting angle about the axis running parallel to the translucent cover is, for example, a maximum of +/- 45 °, and preferably about +/- 35 °. The maximum possible angle of rotation about the axis perpendicular to the translucent cover extending axis is preferably at least 180 °, so that in turn virtually any radiation angle can be adjusted. Again, each one can to limit the pivoting and rotational movements suitable stops are provided.

With regard to the rotational movement of the articulated arm arrangement about the axis extending perpendicularly to the translucent cover, it is advantageous if a spring element, in particular a conical spring, is arranged between the base of the articulated arm arrangement and the housing bottom. By such a spring element, on the one hand inhibits the rotational movement of the joint bracket assembly in a desired manner, so that no unintentional adjustment of a once set pivot angle can occur. On the other hand, the spring element, which is designed in particular as a conical spring, at the same time allows the articulated arm arrangement to run smoothly about the axis perpendicular to the translucent cover so that the desired angle of rotation can be set without jerky movements of the articulated arm arrangement, for example. In addition, a simplified joint construction is possible only by using two flexible discs and said spring element. This structure will be explained in more detail below with reference to FIGS. 12 and 13.

Further preferred embodiments of the invention are specified in the subclaims.

FIGS. 1 to 4 show a substantially square housing frame 10 of a housing 12, the housing 12 (FIG

Installation surface is retractable, so that in the installed position of the housing 12 only the housing frame 10 can be seen. The housing 12 has on two opposite sides holding devices 14, with which it can be fastened in a mounting surface.

In the illumination direction, the housing can be closed in a dust-tight manner by means of a closure surface 16 fitted in the housing frame 10. The closure surface 16 consists of a frame-shaped, substantially square or, for example, also circular EIe- ment, in which a translucent cover 18 is held. In this case, the translucent cover 18 consists of a transparent pane filling the entire frame element of the closure surface 16, on which another slice is placed, which has a central circular recess and at the same time is designed as a diffuser. This composition of the translucent cover 18 of two panes with different translucency causes them in the region of the circular recess of the lens completely transparent and light scattering in those areas in which the lens has no recess. The connection between the translucent cover 18 and the frame element of the closure surface 16 is designed such that no dust can penetrate into the housing 12 when the closure surface 16 (FIG. 1) is closed.

As is apparent from FIGS. 1 to 4, the closure surface 16 is pivotally mounted about an axis in the housing 12, so that the housing 12 can be opened by pivoting the closure surface 16 to perform, for example, a Leuchtmittel-, reflector or filter change can.

Housing inside the translucent cover 18 is connected to a Ausblendring 20, which in particular can be formed integrally with the lens of the translucent cover 18. Alternatively, it could also be clamped over a circumferential, radially outwardly projecting collar between the transparent pane and the diffuser of the translucent cover 18. The Ausblendring 20 extends substantially perpendicular to the translucent cover 18 along that circular line which limits the circular recess of the lens. Thus, the blanking ring 20 separates the transparent area of the transparent cover 18 from its light-diffusing area. Alternatively, to create a smoother and aesthetically advantageous transition from the transparent region to the light-scattering region, the transparent region can be provided on the edge with a screen print. Particularly interesting effects can be achieved in this case if a color filter 42 is arranged in front of the reflector 40. 3 to 5 show that the Ausblendring 20 has two diametrically opposed bearing extensions 22 which extend away from the Ausblendring 20 into the housing interior. In circular openings of the bearing extensions 22, bearing journals 24 of a first cardanic ring 28 are rotatably mounted. Within the first gimbal 28, a second gimbal 30 is rotatably supported in a conventional manner, wherein the axes of rotation of the gimbals 28, 30 extend perpendicular to each other. In this case, each of the two axes of rotation is in each case associated with a worm drive 32, via which in each case a pivoting of the first or second gimbal ring 28 or 30 can be generated.

Each of the two worm drives 32 is connected via a respective flexible shaft 34, each with an adjusting screw 36, which are arranged on the underside and thus on the externally accessible side of the translucent cover 18 in two corner regions thereof. Thus, by means of a rotation of an adjusting screw 36, the respectively associated worm drive 32 can be actuated, which then leads to a pivoting of the first or second gimbal ring 28, 30. Ultimately, the second inner radial ring 30 can thus be pivoted in any direction from its neutral position via the two adjusting screws 36.

On the second gimbal 30 a reflector 40 is held by means of two tension springs 38, which has a dome shape, is closed at its located in the direction of illumination opening with a filter disk 42 and on its back also has an opening through which a light source 44 in the interior of the Reflector 40 can protrude. In the region of its rear opening, the reflector 40 is coupled to a luminous means holder 46, which is arranged at a distance from the reflector 40 such that a light source 44 inserted into the light bulb holder 46 emits most of its light within the reflector 40, but a smaller part of its light also radiates through a gap between the rear reflector opening and the bulb holder 46 into the interior of the housing 12. The latter portion of light passes over the housing inner walls forming an additional or background reflector and the outside of the reflector 40 in the region of the diffusing screen of the translucent cover 18, so that it ultimately exits the translucent cover 18 as a diffuse light. The light entering the interior of the reflector 40, on the other hand, passes through the transparent region of the translucent cover 18 as direct light from the recessed spotlight according to FIGS. 1 to 6.

The recessed spotlight according to FIGS. 1 to 6 is thus dust-tightly sealed when the closure surface 16 is closed by the transparent cover 18 in each pivoting position of the reflector 40, so that no dust can penetrate into the interior of the housing. Furthermore, the respective desired pivot position of the reflector 40 and the associated lamp holder 46 can be adjusted via two externally accessible set screws 36 without the closure surface 16 is opened. Regardless of the respectively adjusted emission angle of the direct light over the transparent region of the transparent cover 18, it is ensured that in each pivoting position of the reflector 40, a small portion of the light generated by the illuminant 44 exits the recessed light via the light-scattering region of the transparent cover 18. Thus, in each pivoting position of the reflector 40, a transparent direct light exit region 48 of the light-permeable cover 18 is separated from a light-diffusing diffuse light source 18. Surrounding area 50 of the translucent cover 18 surrounded. In this case, the Ausblendring 20 ensures an exact separation of diffuse light exit region 50 and direct light exit region 48. At the same time, it is ensured at each pivoting position that the light-permeable cover 18 runs parallel and flush with the mounting surface, so that a uniform appearance can still be achieved when using a plurality of recessed spotlights with differing pivoting positions of the reflector.

An inventive recessed spotlight according to FIG. 1 can be combined with further emitters of the same size, so that a total of elongated luminous fields can be created, which are formed by a plurality of row-like arranged radiators, which are preferably accommodated in a common housing. In this case, it is possible to couple recessed spotlights according to the invention with a pivotable luminous means or reflector for creating accent light with downlights, in which the luminous means or the reflector is not pivotable.

I

FIGS. 7 to 11 show a further possible embodiment of a recessed spotlight according to the invention, in which the pivoting position of the illuminant mount or the reflector is not adjustable from the outside, so that pivoting of the illuminant mount or the reflector can be accomplished in a simple manner Opening the closure surface can be easily achieved.

Those components of the recessed spotlight according to FIGS. 7 to 11, which have their correspondence in components of the recessed spotlight according to FIGS. 1 to 6, have been designated by the reference numerals already used in FIGS. 1 to 6. Analogous to the recessed spotlight according to FIGS. 1 to 6, the recessed spotlight according to FIGS. 7 to 11 has a housing 12 with housing frame IO and a closure surface 16, in the region of which a direct light exit region 48 and a diffused light exit region 50 are formed. In this case, the closure surface 16 in turn has a light-permeable cover 18 whose direct light exit region 48 is separated by a blanking ring 20 from the diffuse light exit region 50. Also in this embodiment, the closure surface 16 is pivotally mounted in the housing 12, so that it does not have to be handled as a separate part when opening.

In the region of the housing bottom opposite the closure surface 16, a hinge bracket assembly 52 is rotatably mounted about an axis perpendicular to the bottom or perpendicular to the translucent cover 18 (in the closed position of the closure surface 16). The hinge bracket assembly 42 has a housing bottom side circular base plate 54, wherein between this base plate 54 and the housing bottom a conical spring 56 (Fig. 10) is arranged, which on the one hand inhibits a rotational movement of the Gelenkbügelanord- tion 52 on the one hand and on the other hand, a jerk-free rotation of the hinge bracket assembly 52 allows.

From the base plate 54, two bail arms 58 extend in the direction of the translucent cover 18, wherein the hinge bracket assembly 52 has a generally substantially V-shape.

At their ends facing away from the base plate 54, the yoke arms 58 each have a bearing point for a circular frame element 60, which is thus pivotably mounted on the yoke arms 58 about an axis which is perpendicular to the axis of rotation of the articulated yoke assembly 52 and extends parallel to the translucent cover 18 in the closed position of the closure surface 16.

By means of two arms 62 which extend from the frame element 60 into the interior of the housing, the frame element 60 is fixedly connected to a light-emitting socket 46, so that ultimately a rotation of the hinge bracket arrangement 52 as well as a pivoting of the frame element 60 causes a rotation or a pivoting cause the bulb holder 46 and the light bulb 44 held therein.

In the area of the pivot axis of the frame element 60, a multifunctional spring 64 is respectively arranged between the frame element 60 and the bowing arms 58, wherein a first function of the multifunctional springs 64 is to inhibit a pivotal movement of the frame element 60 relative to the bowing arms 58 in a desired manner, but to allow such a force when applying a sufficiently large force. Another function of the multifunctional springs 64 is to keep interchangeable in the frame member 60 on the one hand a reflector 40 and on the other a filter disc 42. Both the reflector 40 and the filter disk 42 can thus be detached from the frame member 60 by spreading the multifunctional springs 64 and exchanged, for example, with another reflector (e.g., having a different beam angle) or another filter disk (e.g., a different color filter disk).

The reflector 40 is analogous to the embodiment according to FIGS. 1 to 6 in turn dimensioned so that between the bulb holder 46 and the reflector 40, a gap exists, can get over the light coming from the bulb 44 in the outer region of the reflector 40, so then ultimately to charge the diffuse light exit region 50 beat. In the process, this light component coming from the light source 44 acts, inter alia, on an additional or background reflector 51, which is formed in the region of the housing bottom and extends parallel to it. The additional or background reflector 51 then reflects light either directly and / or via the outside of the reflector 40 and / or via the lateral housing walls and / or over the outside of the skip ring 20 to the diffuse light exit region 50.

Even with the embodiment according to FIGS. 7 to 11, when the closure surface 16 is closed in any pivoting or rotational position of the illuminant mount 46, it is thus ensured that no dust can penetrate into the housing interior and the translucent cover 18 in the sense of a uniform appearance runs parallel to the mounting surface.

A pivoting of the bulb holder 46 is possible after an easy to be done opening the closure surface 16 in that the frame member 60 is taken and rotated in the respective desired position or pivoted. After this process, the closure surface 16 can then be closed again.

FIGS. 12 and 13 show another possible embodiment of a recessed spotlight according to the invention, which is particularly suitable for small designs.

The basic function of the pivoting mechanism of the recessed downlight according to FIGS. 12 and 13 corresponds to that which has already been explained in connection with the recessed downlight according to FIGS. 7 to 11, which means that here too a rotatable articulated arm arrangement 52 with a key spring 56 is provided in which a frame member 60 with arms 62, bulb holder 46 and reflector 40 are rotatably mounted. Again, the reflector 40 is in turn coupled via multifunctional springs 64 to the frame member 60.

Analogous to the embodiment according to FIGS. 7 to 11, the closure surface 16 of the housing 12 is provided with a translucent cover 18 which is fixedly connected to a Ausblendring 20 which separates a direct light exit region from a diffused light exit region.

In contrast to the embodiment according to FIGS. 7 to 11, however, the closure surface 16 is not pivotally mounted in the housing 12. Rather, it can only be deducted from the housing 12 by a linear movement in the direction of the arrows according to FIG. 12. In this case, the withdrawal direction runs perpendicular to the plane of the light-permeable cover 18. An attachment of the closure surface 16 in the housing 12 can take place, for example, according to one of the principles already described in the German patent applications DE 10360948.2 or DE 10 2004 048 484.8 of the applicant.

In the case of a recessed spotlight according to FIGS. 12 and 13, pivoting of the illuminant mount 46 or of the reflector 40 can accordingly take place when the closure surface 16 has been pulled off the housing 12. After the adjustment process, the closure surface 16 can be coupled again to the housing 12, so that the interior of the housing 12 in each pivotal position of the reflector 40 and the

Bulb holder 46 dustproof is completed. In this embodiment, too, it is ensured that the translucent cover 18 extends parallel to the mounting surface of the recessed spotlight in each pivoting position of the reflector 40 or of the illuminant mount 46. With regard to the mounting of the articulated arm assembly 52, FIGS. 12 and 13 show that a portion of the housing bottom and the conical spring 56 come to rest between the base plate 54 of the articulated arm assembly 52 and a counter-pressure disk 55, wherein the base plate 54 and the counter-pressure disk 55 are connected to one another in a rotationally fixed manner. The conical spring 56 comes to lie on the counter-pressure plate 55 facing side of the housing bottom. Between conical spring 56 and housing bottom and also between the housing bottom and base plate 54 each sliding discs can be arranged.
