Description

LUMINAIRE WITH A SWIVELABLE AND SOLVENTLY STORED

LIGHT HEAD

The invention relates to a luminaire with a pivotable and releasably mounted lighthead.

Such a luminaire is known from the prior art, for example in the form of a recessed ceiling luminaire. The light head of the luminaire is suitable for receiving a light source and is pivotably and / or rotatably mounted on a holding element or mounting ring. By a rotation or pivoting of the light head relative to the holding element, the direction of the light output of the lamp can be changed. The light head and the retaining element are firmly connected to each other. In order to install a different lighting technology (eg light color), the complete luminaire, ie the light head and the retaining element, must be replaced or the light head must be dismantled at least laboriously by detaching a plurality of separate fastening means (eg screws, nuts, washers, etc.).

The invention has for its object to provide a correspondingly improved light. In particular, the luminaire is intended to enable simple replacement of the light head, that is to say without removal of the retaining element or costly disassembly.

This object is achieved according to the invention by the subject matters of the independent claims. Preferred embodiments of the invention are specified in the dependent claims.

According to a first aspect, the invention relates to a luminaire, comprising a light head for receiving a light source, and a holding element, wherein the light head is arranged by means of a pivot bearing about a pivot axis pivotally mounted on the holding element. The inventive lamp is characterized in that the pivot bearing has a first connecting part on the holding element and a second connecting part on the light head. At least one of the connecting parts has a first latching element pretensioned in the direction of the pivoting axis towards the other connecting part. The first latching element cooperates with a corresponding second latching element of the other connecting part - ie at least by its bias - in such a way (non-positively) to the Lighthead and the support member in a mounting direction substantially transversely to the pivot axis releasably and to connect pivotally about the pivot axis.

The invention has the particular advantage that due to the bias acting substantially perpendicular to the mounting direction - ie non-positive connection - a mounting and dismounting of the light head is easily and quickly executed. For this purpose, only the light head is to be guided relative to the holding element in the mounting direction. For disassembly, for example, only a manual pulling force is required, which exceeds the bias of the first locking element. Light head and retaining element are thus provided in a modular manner in a simple manner. By providing the pivot bearing by means of a simple frictional connection by bias also the structure of the pivot bearing can be simplified as a whole. In addition, separate fastening means can be dispensed with, since the light (dis) assembly as well as for storage serving biasing function is provided integrated in the pivot bearing.

Preferably, the first latching element has a latching part which is formed so as to project at least partially in the direction of the pivot axis towards the second latching element; So has a prominent area. The second latching element has a recess corresponding to the latching part, in which the first latching element - preferably at least by means of its projecting portion - releasably and pivotally received about the pivot axis and in particular latched snapped. The locking part and the recess thus allow an effective interaction of the two locking elements to form the frictional connection and thus of the pivot bearing.

Preferably, the locking part is at least in a region in which it cooperates with the second locking element - preferably rounded in the above range, round or spherical. Preferably, the locking part is spherical; So a ball. Accordingly, the latching part and the second latching element can be brought independently of a pivot angle of the pivot bearing thus formed in a Zusammenwirkungsposition and kept safe there. Likewise, the forces exerted by the bias forces can be distributed evenly. In addition, in particular allows a spherical configuration a simple, as geometrically induced automatic centering of the pivot bearing components and thus the components light head and retaining element .. Preferably, the first locking element has an elastic element for biasing along - ie in the direction of - the pivot axis and preferably for biasing the locking part in particular to the other connecting part out. The elastic element may be formed, for example, as a spring and in particular a coil spring. Accordingly, the first locking element can be constructed by simple components, which simultaneously allow a reliable and effective bias.

Preferably, the first locking element further comprises a sleeve, in which the elastic element and the locking part are accommodated to form a pressure piece. The sleeve may preferably have seen spring support areas for captive bearings of the spring in the direction of the pivot axis. Likewise, the sleeve Rastteilstützbereiche have seen for captive bearings of the locking member in the direction of the pivot axis. The design as a pressure piece allows the use of simple components for providing the first locking element. The spring support areas are preferably arranged opposite to the latching part with respect to the spring and allow a simple and weight-saving provision of a captive securing the spring. In a comparable manner, the latching part support regions are preferably arranged opposite to the spring support region with respect to the spring and enable a simple and weight-saving provision of a captive securing of the latching part and thus of the components of the first latching element as a whole. Such a pressure piece can thus be handled separately and thus easily provided as part of the pivot bearing.

Preferably, the first connection part has two receiving jaws and a spring element. The two receiving jaws are the first locking element, preferably the sleeve or a sleeve bearing bearing housing, arranged encompassing. The spring element is arranged such that it at least partially surrounds the receiving jaws in order to press the receiving jaws against the first latching element in order to fasten the first latching element, preferably the sleeve or the bearing housing, to the holding element. Accordingly, a simple but firm and secure attachment of the first locking element takes place on the retaining element.

Preferably, the spring element is a wire spring or a leaf spring. This is manufacturing technology advantageous and also allows a particularly simple handling when attaching the spring element to the receiving jaws. Preferably, the receiving jaws are made of plastic. This material is particularly suitable for realizing suitable elastic properties of the receiving jaws. Overall, the entire holding element made of plastic or Metal (eg sheet metal) or other known materials for luminaire body to be made. Similarly, the light head can be made of plastic or metal (eg. Sheet metal or aluminum) or other known materials for lamp body.

Preferably, the receiving jaws and the holding element are integrally formed with each other, whereby both the production and the assembly simplified and few items are required.

Preferably, the pivot bearing on two first connecting parts and two second connecting parts, which are arranged along the pivot axis. Preferably, for this purpose, the first connecting parts on opposite sides of the holding element, preferably inside, and the second connecting parts on opposite sides of the light head, preferably on the outside, are provided. Thus, a stable, since both sides provided and supported connection is made possible by the pivot bearing.

Preferably, the light head has at least two webs, which extend on both sides of the second connecting part substantially in the mounting direction, in order to guide the first connecting part to the second connecting part during assembly of light head and holding element. Accordingly, the mounting of the light head on the holding element in a defined guide can be easily performed.

Preferably, the light head in its mounting direction (ie, the relative direction of movement of the light head for mounting along the mounting direction) as seen in front of the second connecting part on a stop to stop the first connecting part in a mounting position of the light head and holding element in a connecting position of the connecting parts. Accordingly, the stopper defines an end position in the mounting direction. The stop and the webs preferably form a U-shaped mounting guide. This results in a clear mounting direction. All this leads to a further simplification of the assembly.

Preferably, the holding element has an opening in which the light head is detachably and pivotally received. The holding element may preferably be formed as a ring which limits the opening circumferentially. The opening allows easy insertion of the lighthead to its connection position and sufficient clearance for its pivoting. When closed ring is provided The holding element also provided dimensionally stable and can safely act as a mounting ring.

Seen in the mounting direction preferably decreases the width of the light head at least in the region of the pivot axis and more preferably at least in a ramp section, starting from the second connecting part in the direction of its (ie the light head) mounting direction from, preferably steadily. The light head particularly preferably has a substantially cone-shaped form. The lighthead thus forms on its outer surface a kind of insertion bevel, which allows a simple and defined guidance of the lighthead during its assembly up to its connection position with the holding element.

Preferably, the light head further comprises a light source, such as an LED light source (LED: light-emitting diode), for emitting light of the lamp. The light source preferably has a main emission direction. Such a light source basically has a comparatively low weight with high efficiency and a long service life.

The pivot axis preferably extends substantially perpendicular to an optical axis of the luminaire and preferably the main emission direction, which are typically identical. The light output can thus be provided and adjusted as evenly as possible with a view to a possible pivoting range.

Preferably, the light head in a (pivot) range from -90 ° to + 90 ° or - 60 ° to + 60 ° or -45 to +45 or -30 to +30 with respect to the support member is pivotally mounted on this stored. The invention is not limited to the preceding ranges of values. In principle, any pivoting range is conceivable. It is also conceivable that the pivot ranges differ per page. Thus, the lamp allows a freely selectable swivel range and is therefore used in a wide range of applications.

Preferably, the lamp is a ceiling light, such as a ceiling light. Also, the lamp can be designed as an attachment and in principle also as a pendant lamp. The lamp may also independently have a luminaire housing, on which the holding element (releasably) is attached. The luminaire can therefore be used in a wide range of applications. According to a second aspect, the invention relates to a light head for receiving a light source for a luminaire. This has a connecting part of a pivot bearing for pivotally mounted about a pivot axis arranging the light head on a holding element of the lamp. The connecting part has a biased in the direction of the pivot axis first latching element (in this context, hereinafter referred to as Kopfrastelement), which is designed such that it with a corresponding second latching element (hereinafter referred to as a holding latch member) another the connecting element belonging to the holding element - thus at least by its bias - such (non-positively) can cooperate to connect the light head in a mounting direction substantially transversely to the pivot axis and pivotally connected to the support member about the pivot axis.

Accordingly, a light head according to the invention can be provided, which in itself has the advantages described above and can be easily used for the simple provision of the above-described frictional connection. The light head and the connecting part may have all the above-described features of the light head, the connecting part and in particular of the first locking element, so that reference is made to previous versions, which apply equally to the second aspect of the invention.

According to a third aspect, the invention relates to a holding element for the pivotable mounting of a light head of a luminaire, comprising a connecting part of a pivot bearing for pivotably mounted about a pivot axis arranging a light head on the holding element of the lamp,

wherein the connecting part has a first detent element pretensioned in the direction of the pivot axis (in this context also referred to below as a retainer latch element), which is designed such that it corresponds to a corresponding second detent element (in this context also referred to as a top detent element) of another the light head belonging to the connecting part - thus at least by its bias - such (non-positively) can cooperate to connect the light head in a mounting direction substantially transversely to the pivot axis and pivotable about the pivot axis around with the holding element.

Accordingly, a retaining element according to the invention can be provided, which in itself has the advantages described above and can be easily used for the simple provision of the above-described frictional connection. The Retaining element and the connecting part can have all the above-described features of the retaining element, the connecting part and in particular of the first locking element, so that reference is made to previous versions, which apply in the same way for the third aspect of the invention.

The invention will be explained in more detail below with reference to an embodiment with reference to the figures of the accompanying drawings. Show it:

In Fig. 1, a lamp 100 is shown with a light head 1 and a holding element 2 in a disassembled state (exploded view). In Fig. 2, the lamp 100 is shown in an assembled state, wherein the light head 1 and the holding member 2 are releasably and pivotally connected to each other.

In the illustrated embodiment, the lamp 100 is exemplified as a ceiling light, preferably as a ceiling light, designed so that a light output is provided in the lower half space. The luminaire 100 may have a luminaire housing 101 to which the retaining element 2 is fastened. In this case, the holding element 2 can be fixedly connected to the lamp housing 101. However, it is also conceivable that the holding element 2 is movable, for example rotatable, provided on the lamp housing 101, for example, to effect a movement of the light head 1 along a translational movement direction or rotation of the light head 1 about a vertical axis of the lamp 1. The outer side of the light head 1 may have cooling fins 11 (see Fig. 2) to effectively dissipate heat generated during operation of the lamp 100 by the thus provided increased surface area.

The light head 1 is suitable for receiving a light source for the preferably defined light output of the luminaire 100. The light head 1 can consequently have a light source, such as an LED light source, for emitting the light 100 from the light. This preferably has a main emission direction H. As shown in FIG. 7, the light head 1 may have an open side O bounded here by an annular region 4 which forms a light emission opening of the luminaire 100 and through which the light from the light source is emitted to the outside can. In the assembled state illustrated in FIGS. 2, 3, 5, 7 and 8, the light source may preferably be arranged in the light head 1, for example in a receiving space A of the luminaire 100. The open side O may be formed by means of optical elements, such as optics (FIG. Lens, micro-optic plate, conversion plate, diffuser plate, etc.), or any other translucent cover.

In the assembled state of FIG. 2 it can be seen that the lighthead 1 is pivotably mounted on the holding element 2 by means of a pivot bearing 6 about a pivot axis X6. The pivot bearing 6 has a first connecting part 8 on the holding element 2 and a second connecting part 10 on the Lighthead 1 on. As shown in FIGS. 3 and 6, the pivot bearing 6 may also comprise two (or more) first connecting parts 8 on the holding element 2 and two (or more) second connecting parts 10 on the light head 1.

At least one of the connecting parts 8, 10 has a first detent element 12 pretensioned in the direction of the pivot axis X6 in relation to the other connecting part 10, 8. In the exemplary embodiment illustrated, each first connecting part 8 has a first latching element 12, which, as seen in the direction of the pivoting axis X6, is biased towards one of the second connecting parts 10 in the assembled state. It is also conceivable that every second connecting part 10 has a first latching element 12. In a multi-part pivot bearing 6, it is also conceivable that once the first connecting part 8 and once the second connecting part 10 has a first locking element 12.

In each case, the respective other connecting part 10, 8 has a second latching element 14 which corresponds to the first latching element 12. In the exemplary embodiment shown, therefore, each second connecting part 10 has a second latching element 14, which is designed to correspond with a respective associated first latching element 12.

In the example shown (FIGS. 7-8), the first connecting parts 8 are provided along the pivot axis X6 and on opposite sides of the retaining element 2 -in this case preferably inside. Accordingly, the second connecting parts 10 on opposite sides of the light head 1 - here preferably outside - provided.

The first locking element 12 of a connecting part 8, 10 cooperates with the corresponding second locking element 14 of the other connecting part 10, 8 - ie at least or in particular by its bias - (non-positively) to the light head 1 and the support member 2 in a mounting direction Z2 substantially transversely to the pivot axis X6 releasably and to pivot around the pivot axis X6 around. For the illustrated embodiment, this means that here each of the two first locking elements 12 is adapted to cooperate with the respective corresponding second locking element 14 - at least or in particular by its bias - such (non-positively), so that they the light head 1 and the Retaining element 2 in a mounting direction Z2 substantially transversely to the pivot axis X6 releasably connect and pivotable about the pivot axis X6 around. Despite easy to be provided Verbindungsart, which is preferably provided solely non-positively by bias, a secure connection of the lamp components 1, 2 can be provided, which also allows pivoting of the light head 1 relative to the support member 2 to change the direction of the light output of the lamp 100 and to set arbitrarily. The pivot axis X6 may extend horizontally when the lamp 100 is disposed on or in a horizontal ceiling. In the example shown, the light head 1 is pivotally mounted on the holding element 2 in a range of -30 ° to + 30 °. Fig. 6 shows the light head 1 with respect to the support member 2 inclined by + 30 °. However, for example, depending on the geometry of the luminaire components 1, 2-, other pivoting ranges on both sides are conceivable. The luminaire 100 or the light head 1 has an optical axis Z1, which extends substantially perpendicular to the pivot axis X6. Likewise, the pivot axis X6 preferably extends perpendicular to the main emission direction H of the light source. The optical axis Z1 and the main emission direction H are preferably coaxial. When the lighthead 1 is in a middle position of its pivotable range (-30 °, + 30 °), the optical axis Zl includes an angle Z1.Z2 of 0 ° with the mounting direction Z2. In a position pivoted with respect to this central position, as shown for example in FIG. 5, the optical axis Z1 encloses an angle Z1.Z2 of> 0 ° with the mounting direction Z2. As shown in the exemplary embodiment shown (FIGS. 7-8), each first latching element 12 may have a latching part 16 which is formed so as to protrude in the direction of the pivoting axis X6 relative to the respective second latching element 14. In the exemplary embodiment shown (FIGS. 7-8), each second latching element 14 then has a recess 18 that corresponds to the latching part 16, in which the first latching element 12, in particular the latching part 16, is detachable and pivotable about the pivot axis X6, preferably by means of its protruding area is included. With reference to FIG. 9, the recess 18 may be formed by a passage opening, such as a through-hole, through the light head 1, which extends from the outside to an inner side preferably bounding the receiving space A. On the inside, this passage opening 18 can then serve as a locking receptacle for lighting components; here, for example, a reflector R. The recess 18 may for example have a round or rectangular (for example, square) cross-section. In particular, the locking member 16 may be snapped detent in the corresponding recess 18 when the lamp 100 is in the assembled state. The latching part 16 may be formed at least in a region in which it interacts with the second latching element 14, preferably in the protruding region, rounded, round or spherical. As shown in Fig. 4, 5 and 9, the locking member 16 may be spherical, so a ball. Such a locking part 16 can cooperate by its spherical or rounded surface in any position with the second locking element 14 accordingly.

Each first latching element 12 may have an elastic element 20 which provides the bias for the detachable and pivotable mounting of the light head 1 with respect to the holding element 2 along the pivot axis X6. In the exemplary embodiment shown, the elastic element 20 can exert a resilient force on the latching part 16 in the direction of the respective second latching element 14. The elastic member 20 preferably has a (compression) spring, such as a coil spring.

By the biased elastic element 20 here, for example. On the locking part 16 transmitted spring forces the locking member 16 is pressed into the recess 18 and centered therein due to the cross-sectional shape of the recess 18 therein. Pressed into the recess 18, the connecting parts 8, 10 exert oppositely directed holding forces in the direction of the pivot axis X6, via which the light head 1 - against the spring force - releasably and at the same time pivotally connected about the pivot axis X6. Each of the locking parts 16 shown can transmit part of these spring forces to the respective recess 18. The spring forces may be determined to exert sufficient vertically directed holding or friction forces to maintain the weight of the lighthead 1. In addition, a positive connection can be provided by the protruding region of the latching part 16 received in the recess 18, so that the spring forces can be correspondingly reduced. Thus, the light head 1 is attached to the holding element 2. The projecting region of the locking part 16 should preferably protrude only so far into the recess 18 that a release of the light head 1 in the mounting direction Z2 by an operator is possible; Thus, the locking member 16 moves during disassembly against the spring force in the direction of the pivot axis X6 and thus releases the connection. The contacting surfaces of the first 12 and second 14 locking elements may be formed so as to promote the above-described frictional forces. Furthermore, each first detent element 12 may have a sleeve 22, in which the respective elastic element 20 and the respective detent part 16 are received, preferably at least in the assembled state, so that the elastic element 20 and the detent part 16 together with the sleeve 22 Form pressure piece. The sleeve 22 may have spring support areas 22.20 for the captive storage of the elastic element 20 and locking part support areas 22.16 for the captive storage of the locking part 16 in the direction of the pivot axis X6. The spring support regions 22.20 of the sleeve 22 are here preferably arranged opposite the latching part 16 with respect to the elastic element 20. In the same way, the latching part support regions 22.16 of the sleeve 22 can be arranged opposite the spring support regions 22.20 with respect to the elastic element 20. Accordingly, each elastic member 20 is securely supported in the sleeve 22. Furthermore, each locking part 16 in the sleeve 22 in the direction of the pivot axis X6 can move reliably.

Furthermore, each first connecting part 8 preferably comprises two receiving jaws 24 and a spring element 26. The receiving jaws 24 are arranged such that they engage around the first locking element 12, preferably the sleeve 22 or a bearing housing 23 carrying the sleeve 22. The spring element 26 is arranged such that it at least partially surrounds the receiving jaws 24 in order to press the receiving jaws 24 against the first detent element 12 so that the first detent element 12, preferably the sleeve 22 or the aforementioned bearing housing 23, is fastened to the holding element 2 becomes. The receiving jaws 24 may be formed approximately elastically, for example, from a plastic, so that the respective sleeve 22 - possibly accommodated in the bearing housing 23 - to push the assembly 100 of the lamp 100 between the two receiving jaws 24 or can be pressed. In the illustrated embodiment, the receiving jaws 24 and the holding member 2 are formed integrally with each other, which can be realized, for example, that the entire holding member 2 is made as a plastic injection molded part. The light head 1 may in turn preferably be formed as Aluminiumdruckgußteil. As shown in Fig. 4, the spring element 26 may be designed as a wire spring. Alternatively, the spring element may also be designed as a leaf spring and the like.

As shown in FIGS. 1, 2, 7 and 8, the light head 1 preferably has (depending on the number of second connecting parts 10) two webs 28, which extend on both sides of a respective second connecting part 10 essentially in the mounting direction Z2. The Webs 28 are designed and provided such that they guide the respective first connecting part 8 to the respective second connecting part 10 in the assembly of light head 1 and holding element 2.

The light head 1 can, seen in its mounting direction Z21, have a respective stop 30 in front of each second connecting part 10. Each stopper 30 is formed and provided so as to stop the corresponding first connecting part 8 when the light head 1 and the holding member 2 are mounted in a connecting position of the connecting parts 8 and 10. The stop 30 and the associated webs 28 preferably form a U-shaped mounting guide and thus a kind of "bag" to allow safe and clear guidance during assembly. This "pocket" particularly preferably forms a corresponding mating contour for receiving the first connecting part 8.

Furthermore, the holding element 2 preferably has an opening 32 in which the light head 1 is detachably and pivotally received or inserted. In the embodiment shown, the holding element 2 is formed as a ring which limits the opening 32 circumferentially. The lighthead 1 is formed so that it can be inserted through the opening 32 for mounting. In the assembled state, the light head 1 is preferably arranged in the opening 32 such that, viewed in a side view, it does not project from the holding element 2 when viewed in a pivoting state in the mounting direction Z 2. The invention is of course not limited thereto.

As can be seen in FIGS. 1 and 8, the width of the light head 1, viewed in the mounting direction Z2, preferably decreases starting from the second connecting part 14 in the direction of its mounting direction Z2 at least in the region of the pivot axis X6, shown here continuously. The light head 1 preferably has a substantially cone-shaped form. Such a decreasing width of the light head 1 can form a kind of insertion bevel and then preferably allows a simple sliding and snapping the connecting parts 8, 10. However, it is also conceivable that as a ramp (additionally or alternatively) provided a ramp portion 29 and preferably with the lighthead 1 is integrally formed, which further preferably ends at the stop 30 or in the "pocket" (see Fig. 7). The width of the light head 1 is to be measured perpendicular to the optical axis ZI. During assembly of the light head 1, the first latching elements 12, preferably their latching parts 16, slide along the outer surface of the light head 1 or on its ramp section 29 and are increasingly pretensioned due to the then increasing width of the light head 1 or ramp section 29. At the corresponding second Detent element 14, here the recess 18, arrived, the locking member 16 then snaps into the recess 18 and forms the releasable latching and pivoting connection.

The holding element 2 may further have an abutment edge 34 which is provided for abutment with an edge region of a mounting opening or - as shown - on the lamp housing 101 of the lamp 100. Accordingly, the abutment edge 34 preferably extends parallel to a plane of the mounting surface (eg, ceiling or wall) when the retainer 2 is in an operative position. The lamp 100 or the holding element 2 may further comprise a retaining ring 7. By means of this, for example, the retaining element 2 can be fixedly mounted on the lamp housing 101. However, it is also conceivable that the retaining ring 7 is part of a sliding ring bearing to the support member 2 rotatable - in this case preferably by a mounting direction Z2 extending vertical axis - and thus to increase the degrees of freedom of the alignment of the light head 1.

During operation of the luminaire 100, a user may manually pivot the lighthead 1 about the pivot axis X6 (and possibly further rotate about the vertical axis) to adjust the orientation of the light output. Due to the bias, the first connecting parts 8 exert on the second connecting parts 10 holding forces in the direction of the pivot axis X6, so that a pivotable holding or latching connection is provided. Preferably, by means of spring forces, the lighthead 1 is snap-latched to the holding element 2. Several portions of the lamp 100, and the light head 1 and the support member 2 may be designed to be conductive, for example. Of metallic materials to conduct an electric current through the support member 2 and the light head 1 to the light source.

To disassemble the light head 1, the light head 1 simply has to be pulled with a certain tensile force counter to its mounting direction Z21, that is to say in the dismounting direction Z22, as shown in FIGS. 7-9. The tensile force only has to exceed the holding or friction forces between the connecting parts 8, 10 or the latching elements 12, 14. According to the exemplary embodiment illustrated in FIG. 9, during disassembly, each latching part 16 is preferably pressed against the upper edge of the recess 18 shown here. Due to its spherical shape, the force acts obliquely on the ball 16, so that a portion of the force results in the direction of the pivot axis X6, as symbolized by the arrow 16.4. If this force exceeds the spring force exerted by the elastic element 20, it pushes the latching part 16 out of the recess 18 until the snap-in latched connection is released and the light head 1 is removed from the holding element 2 in the dismounting direction Z22 can. By the here oblique outer surface of the light head 1, the disassembly is preferably facilitated.

Overall, a simple or fast assembly and disassembly of the light head 1 is possible, which leads to significant advantages over previously known solutions.

As already mentioned, as an alternative to the illustrated example, the latching part, or each latching part, of the first latching element may be arranged on the light head and the corresponding recess, or the respective recess, of the second latching element may be provided in the holding element. Thus, the pivot bearing of this alternative embodiment is formed inversely with respect to the embodiment shown.
