Description

Luminaire with a luminaire housing comprising a profile element

The invention relates to a luminaire, which has a luminaire housing with a profile element.

Such a lamp in the form of a radiator is known from EP 2 138 763 A2. The spotlight has a luminaire housing, which is shown in the open state in FIG. 12. The luminaire housing is intended to be mechanically and electrically connected via adapters 150, 150 'to a busbar system (not shown). The luminaire housing comprises a profiled-shaped bottom part 380, to which a luminaire head sleeve 200 for a lighting head or luminaire head 20 is fastened, which can be adjusted relative to the luminaire housing in different positions. To attach the sleeve 200 to the bottom part 380 is an L-shaped holding member made of sheet metal, which is riveted to the bottom part 380.

In the lamp head 20, an LED light source (LED: light-emitting diode) is arranged, for their operation, the lamp further comprises an operating device 60; this is also in the luminaire housing, in an upper one

Recording room 50 arranged.

Fig. 13 shows a corresponding bottom part of another, similar lamp. In this embodiment, the operating device 60 is mounted on the bottom part 380. The holding elements are here designed as folded sheet metal parts and fixed to the bottom part 380 with grub screws.

The attachment of the holding element or the holding elements to the bottom part 380 of the lamp housing requires a not inconsiderable cost and

Assembly effort in the production of the lamp.

The invention has for its object to provide an improved light.

In particular, the lamp should allow easier installation and

can be designed inexpensively. This object is achieved according to the invention with the object specified in the independent claim. Particular embodiments of the invention are indicated in the dependent claims.

According to the invention, a luminaire is provided, which has a luminaire housing with a profile element, as well as a holding element arranged on the profile element for holding a further luminaire component. In this case, the lamp is designed such that the holding element is arranged on the profile element held only via a latching connection.

With this configuration, the holding element can be particularly easily connected to the profile element. In addition, no separate fastening element for fastening the retaining element to the profile element is required. Thus, the lamp can be very simple and time-saving

assemble.

The fact that the latching connection acts on the profile element, can also achieve that the holding element viewed in the longitudinal direction of the profile element can basically be mounted at any point or position.

The holding element is particularly suitable if it is in the other

Luminaire component is a lamp head sleeve and / or a control gear of the lamp.

Preferably, the latching connection has at least one latching element formed on the holding element. As a result, a simple attachment of the holding element to the profile element is facilitated for mounting of the holding element. In addition, a corresponding separate component can thereby be avoided or saved.

A particularly simple production of the holding element and assembly of the

Retaining element on the profile element can be effected if the holding element consists of plastic. Preferably, the latching connection is designed such that it can be produced without tools and preferably reversibly can be solved again. As a result, the assembly of the lamp is further facilitated. A particularly simple assembly is further made possible when the latching connection is designed such that it can be produced by a rotational movement of the holding element relative to the profile element. Preferably, the lamp is further designed such that the rotational movement takes place about an axis of rotation which extends at right angles or parallel to a longitudinal axis of the profile element.

Preferably, the holding element has a lug element for an operating device of the luminaire. As a result, attaching the operating device is facilitated.

The retaining element preferably has a strain relief element. This can save a separate part to the strain relief.

Preferably, the holding element has a cable guide. This makes it possible to save a separate part for guiding a cable to operate the lamp. Preferably, the profile element is a cover of the lamp housing.

Fig. 13 is a sketch of another lamp according to the prior

Technology. In Fig. 1 is a sketch of a lamp according to the invention is shown. One recognizes a profile element 2, the part of a (otherwise not shown in the figure)

Luminaire housing forms. In particular, the profile element 2 may be a cover element of the luminaire housing, preferably - as in the example shown, the case - around a bottom part of the luminaire housing.

In the present description, it is assumed that the profile element 2 limits the rest of the luminaire housing downwards or covers it from below. Fig. 1 shows accordingly a view obliquely from above. The luminaire housing is designed so that it in the assembled state of the lamp sketched in Fig. 1, encloses further parts. In that regard, the embodiment corresponds to the known lamp shown in Fig. 10.

However, the above-mentioned embodiment as a cover element from below is not mandatory. The profile element 2 may for example be configured alternatively for a lateral cover of the lamp housing. In principle, the invention is suitable for any orientation of the profile element. Only the simpler

Description is here assumed that it is the profile element 2 is a bottom part. If necessary, the directions etc. are to be reinterpreted accordingly.

Due to the shape of the profile element 2, a longitudinal axis L is fixed. In Fig. 5, the profile element 2 is sketched slightly larger. The profile element 2 has two edge regions, which extend parallel to the longitudinal axis L, wherein at a first of the two edge regions, a first upwardly directed leg 21 is formed and at a second of the two edge regions, a second upwardly directed leg 22. The rest Part of the profile element 2 is preferably designed at least substantially plate-shaped, so that the profile element in cross section is so to speak slightly C-shaped. More generally formulated so the two said legs 21, 22 are directed toward an interior of the lamp housing above.

The first upwardly directed leg 21 has a shoulder leg 211 which points in the direction of the second upwardly directed leg 22. In addition, at the first upwardly directed leg 21 is preferably still another

Shoulder leg 212 is provided, which is formed on the, the first-mentioned shoulder leg 211 opposite side. The last one, more

Shoulder leg 212 is for fastening the profile element 2 to the

Luminaire housing provided. The profile element 2 is preferably formed symmetrically, with respect to a vertical plane of symmetry, which is oriented parallel to the longitudinal axis L.

Accordingly, the second upwardly directed leg 22 has corresponding shoulder legs 221, 222. Referring again to Fig. 1, the lamp further comprises a holding element 3, which is designed to hold a further lamp component, here in the form of a control gear 6 of the lamp. In Fig. 3, the holding element 3 is sketched in a separated form of obliquely below, in Fig. 4 in a corresponding manner obliquely from above.

The lamp is designed such that the retaining element 3 is arranged on the profile element 2 only - as indicated in Fig. 1 - via a latching connection R is held. As a result, the holding element 3 can be fastened or mounted particularly simply on the profile element 2.

For this purpose, the retaining element 3 preferably has at least one latching element 7-shown by way of example in FIG. 3. In the example shown, the latching element 7 is designed to cooperate with the latching connection R with the shoulder limb 211 of the first upwardly directed limb 21 of the profile element 2. Preferably, the holding element 3 also has a further latching element 71, which is configured to cooperate with the latching connection R with the shoulder leg 221 of the second upwardly directed leg 21 of the profile element 2, so that the two latching elements 7, 71 in opposite directions against the profile element Press 2 when the locking connection R is made as intended.

A particularly good stability of the connection can be achieved if the

Retaining element 3 also has two further locking elements 72, 73, which are configured analogously to the two first-mentioned locking elements 7, 71, with respect to the longitudinal axis L at a different location.

Particularly suitable is the holding element 3 made of plastic, in particular it may be a plastic molding. Further preferably, it is integrally formed.

With the embodiment shown here can be achieved that the locking connection R can be made without tools. It can also be solved without tools; Preferably, the design is such that the holding element 3 with the Profile element 2 can be reversibly connected via the locking connection R and also released again.

In Fig. 8 is outlined how the holding element 3 can be mounted on the profile element 2. In the example shown, the latching connection R is designed such that it can be produced by a rotational movement of the holding element 3 relative to the profile element 2. For this purpose, the holding element 3 can first - in an oblique position - with the two locking elements 71, 73 are attached to the second upwardly directed leg 22 of the profile element 2 - as in Fig. 8 with a position / indicated. Subsequently, the holding member 3 can be rotated about a rotation axis D, which extends parallel to the longitudinal axis L until the locking elements 7, 72 engage for the production of the locking connection R snap under the shoulder leg 211 and thus finally reached a position II, which is the one for Operation of the lamp provided relative arrangement between the support member 3 and the profile element 2 corresponds. The holding element 3 can be clipped on the profile element 2, so to speak.

By means of this configuration, it can be achieved, in particular, that the holding element 3 can in principle be mounted at any point on the profile element 2 with respect to the longitudinal axis L.

As shown by way of example in FIG. 4, the retaining element 3 preferably also has an attachment element 8 for the connection to the operating device 6. In the example shown, the lug element 8 is formed by two upwardly projecting shoulders 81, 82 which extend parallel to the longitudinal axis L. As a result, the operating device 6 can be connected relative to the holding element 8 with the latter in different longitudinal positions. The operating device 6 must therefore not be pinpointed for connection to the holding element 3 - with respect to the longitudinal axis L. In this way, the assembly of the operating device 6 is facilitated.

Preferably, the design is such that the operating device 6 can be connected without tools for attachment to the holding element 3 with the latter. The neck element 8 is basically suitable for different

Control gear.

Furthermore, the retaining element 3 preferably comprises a strain relief element 9 in the example shown here. The strain relief element 9 is configured for strain relief of an electrical cable (not shown in the figures) which is provided for a current connection to the operating device 6.

In the embodiment shown here, the strain relief element 9 is U-shaped, so that it has two U-legs 95, 96 and one, the two U-legs 95, 96 connecting connecting leg 99; the two U-legs 95, 96 have - with respect to the U-shape - inwardly facing rows of teeth. Furthermore, the holding element 3 has two receiving areas 93, which are designed for latching receiving the two U-legs 95, 96 and accordingly each have an outwardly facing edge, for an interaction with the corresponding row of teeth of the respective U-leg 95 and 96 is formed.

In the example shown, the two receiving areas 93 are vertical

extending, upwardly open openings formed so that the strain relief element 9 with its two U-legs 95, 96 can be inserted from above into the receiving areas 93. Alternatively, the receiving areas 93 may be formed, for example, by lateral recesses of the holding element 3.

Between the two receiving regions 93, a first pressure surface 98 is formed and on the connecting leg 99, a second pressure surface 97, wherein the two said pressure surfaces 98, 97 configured for compressing the electric cable.

Preferably, the design of the holding element 3 is such that in a first state of the holding element 3, the strain relief element 9 with the rest

Retaining element 3 only via at least one predetermined breaking point, here over two

Predetermined breaking points 91, 92 is connected. For assembly, this connection can then be easily solved - for example by a kink - and in the following

Strain relief element 9 with its two U-legs 95, 96 from above into the two Insert receiving areas 93, wherein between the two pressure surfaces 98, 97, the cable is clamped to the strain relief. In Fig. 1, a state is sketched in which the strain relief element 9 is connected in accordance with the rest of the holding element 3 (in the drawing without cable).

Further preferably, the holding element 3 has at least one - sketched by way of example in FIGS. 3 and 4 - another attachment element 11 for a clip 10, sketched in FIG. 1, for the cable. In the example shown, the further attachment element 11 is designed in the form of at least one recess or a hole into which the clamp 10 can be inserted in engagement with a correspondingly corresponding projection.

As further sketched by way of example in FIG. 1, the luminaire also has a further retaining element 4. In Fig. 5, the further holding element 4 is shown at a shorter portion of the profile element 2 from another viewing direction. Figures 6 and 7 show the further holding element 4 in a separated form of two

different view directions from diagonally above.

The further retaining element 4 is designed to hold a lamp head sleeve 5. The lamp head sleeve 5 serves to receive a lamp head 50, which has a light source, for example an LED light source for emitting light of the lamp. The design is preferably such that the lamp head 50 is movably mounted relative to the lamp head sleeve 5, in particular in a vertical direction along a vertical axis A. In the lower extension of the

Lamp head sleeve 5 is for this purpose in the profile element 2, a circular opening formed through which the lamp head 50 along the axis A can be moved up and down.

For holding the lamp head sleeve 5, the further holding element 4 has an upwardly directed extension 41. In the example shown, a bracket 52 is arranged around this extension 41 and the lamp head sleeve 5, so that preferably the lamp head sleeve 5 is rotatably mounted about the axis A on the extension 41. At its lower end region, the further holding element 4 preferably has a concave bulge 47, which in its curvature to the shape of the

Lamp head sleeve 5 is adjusted. It is preferably designed such that it forms a bearing or sliding surface during a rotational movement of the lamp head sleeve 5 about the axis A.

The extension 41 preferably has at its upper end a nose 411, which serves as a rotation stop for a rotary movement of the lamp head sleeve 5 about the axis A. Further preferably, the further holding element 4, a neck element 42 for the operating device 6, which is preferably analogous or identical to the

corresponding extension element 8 of the first-mentioned holding element 3 is formed. Preferably, the neck element 42 of the further retaining element 3 is formed directly adjacent to the extension 41.

As indicated in FIG. 1, the design is preferably such that the operating device 6 is supported, on the one hand, on the retaining element 3 and, on the other hand, on the further retaining element 4. The further holding element 4 is - as well as the first-mentioned holding element 3 - via a latching connection R 'mounted on the profile element 2. For this purpose, the further retaining element 4 has two latching elements 43, 44, which are designed to engage under the two mutually facing shoulder legs 211, 221 of the two upwardly directed legs 21, 22 of the profile element 2.

In Fig. 9 is outlined how the further retaining element 4 can be mounted on the profile element 2. In the example shown, the latching connection R 'is designed such that it can be produced by a rotary movement or sliding rotational movement of the holding element 3 relative to the profile element 2, wherein the rotational movement in this case about a vertical axis of rotation D ^' .

To produce the latching connection R ', the further holding element 4 is first - with respect to its intended position rotated by 90 ° - with the two

Locking elements 43, 44 between the two upwardly directed legs 21, 22nd set. This is indicated in Fig. 9 with a position /. Subsequently, the further retaining element 4 - as indicated by a position II - rotated about the axis of rotation D 'until the two locking elements 43, 44 finally in their intended

Engaging positions of the shoulder legs 211, 221 engage under, as indicated in a position III.

It can also be achieved by means of this configuration that the retaining element 3 can in principle be mounted at any point on the profile element 2 with respect to the longitudinal axis L.

The said movement of the further holding element 4 for producing the connection can be facilitated if the two latching elements 43, 44 each have convexly shaped starting areas 431, 441. Further preferably, the further holding element 4 has at least one

Cable guide 48, preferably two cable guides 48, which are formed in particular extending parallel to the longitudinal axis L extending. The two cable guides 48 are preferably formed on two opposite sides of the lug element 42, in particular at a level below the lug element 42.

In the example sketched in FIG. 1, in addition to the first-mentioned holding element 3, there is also provided a second holding element 3 ', which is configured identically to the first-mentioned holding element 3. Hereinafter, these holding elements 3, 3 'are referred to as holding elements of a "first type".

Analogously, in addition to the further holding element 4 also has a second, too

The latter analogously or structurally designed holding element 4 'provided, and a corresponding third holding element 4 ^" - hereinafter these holding elements 4, 4 ^' , 4 ^" correspondingly referred to as holding elements of a "second type".

In the sketched in Fig. 1 arrangement are on the profile element 2 two

Support members 3, 3 ^'of the first type are provided and a total of three holding members 4, ^4', 4 ^"of the second type. In the sketched in Fig. 2 variant of the profile element 2, two holding elements 3, 3 ^'of the first type are provided and exactly one support member 4 of the second type. 1, three lamp head sleeves 5, 5 ', 5 "are provided and only one lamp head sleeve 5 is provided in the arrangement sketched in Fig. 2. Generally, two retaining elements 3, 3 ^{' of} the first type are preferably provided and at least one retaining element 4 of the second type.

The two holding elements 3, 3 ^'of the first type are - with respect to the longitudinal axis L - preferably arranged at two opposite end portions of the profile element 2 while rotated each other by 180 ° to each other, so that the two strain relief elements facing outward. These two holding elements 3, 3 ^'of the first type can serve as a terminal holder and Zugentlaster for through wiring of the lamp. As indicated in FIG. 10, preferably the retaining element 4 or one of the

Holding elements 4 of the second type together with one of the two holding elements 3, 3 '- here with the holding element 3 - of the first type for holding the operating device 6 is provided. For this purpose, in particular, an adapter plate 11 may be provided, which is designed so that it can be plugged onto the two corresponding attachment elements 8, 42 of the two holding elements 3, 4, as indicated by two arrows in Fig. 10. On the adapter plate 11 can then - as shown in Fig. 11 - in a further step, the operating device 6 are attached.

Referring again to the arrangement shown by way of example in FIG. 1, a first retaining element 4 of the second type may be used to support a first lamp head sleeve 5. The two further holding elements 4, 4 ^'of the second type each serve to hold another lamp head sleeve 5 ^' , 5 ^" . The holding elements 4, 4 ^' , 4 ^{" of} the second type are - with respect to the longitudinal axis L - between the two holding elements 3, 3 'of the first type arranged.

The invention makes it possible to achieve that the luminaire can be produced in a significantly reduced assembly time and thereby with a reduced number of components.
