Description

The invention relates to a multi-part housing body, consisting of at least a first housing part and a second housing part that is articulated to the first housing part, wherein the first housing part has a busbar connection and the second housing part has a functional carrier with lighting means, wherein the first and second housing parts furthermore have an elongated, essentially rectangular basic shape with opposite longitudinal and end sides and by means of the articulated connection the second housing part can be pivoted towards and away from the respective longitudinal side of the first housing part, according to the preamble of claim 1.

From the EP 2 088 367 B1 A luminaire, in particular a surface luminaire, with a housing accommodating a light source and the associated electrical components, as well as a frame associated with the housing for holding a light-diffusing light exit surface is previously known.

The frame is pivotably connected to the housing of the luminaire at the front and can be pivoted between an opening position ensuring free access to the lamps and a closing position preferably flush with the opening plane of the housing.

At least one pair of flat links, each located in one plane, is provided for the pivoting connection between the housing and the frame, with the pair of flat links being hinged on the one hand to the inner wall of the housing and on the other hand to the outside of the front wall of the frame. In the closed position of the frame, the pair of flat links is mounted in the gap area between the inner wall of the housing and the frame.

The previously known pair of flat links consists of a support link and a control link, which are connected to articulation points on the housing and the frame that are offset relative to one another in such a way that a virtual pivot axis is formed in the rear area of the lamp and wherein the links do not hinder free accessibility of the interior of the housing.

Opening and closing positions are defined by stops.

A retaining spring is effective in the closed position of the frame.

The functional carrier for the construction of light strip systems according to DE 10 2020 115 009 B4 A profile body is assumed which includes a component receiving space.

The component receiving space is delimited on the one hand by two parallel legs with longitudinal grooves and on the other hand by a leg connecting section.

A profile strip which is at least partially transparent to visible radiation and has longitudinal edges complementary to the longitudinal grooves can be introduced into the longitudinal grooves.

In order to maintain the inherent rigidity of the functional carrier, the profile strip is provided with a large number of pin-like stops as well as locking hooks distributed along its length.

The in DE 10 2020 115 009 B4 The functional carrier described can be used both for the construction of comprehensive light strip systems and for individual luminaires.

From the DE 10 2012 206 070 A1 A lamp with an elongated lamp housing for wall and/or ceiling mounting is already known. The lamp comprises a plurality of light-emitting diodes. Furthermore, a holding device is provided for setting a rotational position between the lamps and the lamp housing. The holding device comprises a joint which is arranged between a housing-side fastening point, via which the holding device is fastened to the lamp housing, and a lamp-side fastening point, via which the holding device is fixed to the lamp with the LEDs.

The EP 2 413 028 A2 discloses a support arrangement for at least one lamp. The support arrangement is displaceable in the longitudinal direction relative to a support system.

Furthermore, a joint arrangement is formed between the carrier and the lamp body(s) with lamps in order to be able to pivot the lamps and thus realize different beam angles.

When arranging the lights according to CN 209180799 U A controllable joint is provided on a support for lamps, whereby the joint is actuated hydraulically and/or temperature-controlled. The lamps are located on a support plate and comprise a large number of light-emitting diodes. The joints in question engage the respective support plate and enable the angular position of the support plates to be varied.

The luminaire with a variety of LED bulbs according to US 2011/0297971 A1 comprises an elongated lamp body with a cover over the light sources. The cover is removable and can be attached to the lamp by means of a latch. The lamp itself can be clamped and pivoted into an outer housing using an axle construction with corresponding bearing elements.

Luminaires that have a movable track adapter are also known, for example for use in illuminating objects in retail stores.

With such luminaires, a changed position can be achieved according to the objects to be illuminated using existing power rails.

However, track adapters only allow the corresponding light to be moved lengthwise and to have a certain degree of rotation. If the light is to be swiveled out of its intended fixed plane, the light must generally have a corresponding swivel bearing.

However, solutions for pivoting a lamp body in relation to a housing with a busbar adapter require additional installation space and lead to increased manufacturing costs. Particularly with the increasing use of light-emitting diodes as light sources, the aim of lamp designers is to develop particularly flat or small lamps. However, the integration of joints or pivot bearings in or for such small lamps often leads to a restriction of design options or to products that are not very aesthetically pleasing.

From the above, it is therefore the object of the invention to provide a further developed multi-part housing body, in particular for lights, which, starting from a first housing part and a pivotable second housing part, avoids the disadvantages of the prior art, can be designed to be small or flat and in which the means for pivoting can be implemented in a structurally simple manner and the manufacturing costs can be low.

The object of the invention is achieved by a multi-part housing body according to the complex of features of patent claim 1, wherein the subclaims comprise at least expedient embodiments and further developments.

It is therefore assumed that there is a multi-part housing body which consists of at least one first housing part and at least one second housing part.

The second housing part is hingedly connected to the first housing part.

A busbar connection is formed on the first housing part.

The second housing part accommodates a functional carrier with light sources.

This may in particular be a functionary of the type described in the DE 10 2020 115 009 B4 described solution.

The first and the second housing part have an elongated, substantially rectangular, in particular rectangularly flat basic shape with opposite longitudinal and end sides.

By means of the articulated connection, the second housing part can be pivoted towards and away from the respective long side of the first housing part.

The pivoting capability therefore allows the lighting elements arranged in or on the functional carrier to be aligned with respect to the object to be illuminated.

The lamps can be provided in a known manner with an opaque cover or with a beam-directing cover consisting of a large number of individual lenses.

In this regard, reference should also be made to the teaching of DE 10 2020 115 009 B4 made aware of.

According to the invention, at least one flat, hook-shaped extension extends from each of the end faces of the first housing part, which extends into a slot-shaped opening in the upper side of the second housing part.

A hook end of the extension received in the second housing part and located there has a recess, in particular a bore, for receiving a pivot axis, which corresponds to an axis bearing in the interior of the second housing part.

The desired pivoting of the second housing part can then be carried out around this pivot axis in relation to the fixed position of the first housing part.

The axle bearing located in the second housing part is preferably designed as a stamped and bent part and inserted in the second housing part. The stamped and bent part can be part of the above-mentioned functional carrier.

With the construction of the multi-part housing body explained above, both a single-flame pivoting luminaire and a multi-flame luminaire, in particular a two-flame luminaire, can be realized.

In this regard, starting from a longitudinal axis of symmetry of the first housing part, two flat, hook-shaped extensions are formed in a mirror image on the respective end faces of the first housing part in such a way that two separately pivotable second housing parts with respective slot-shaped openings are connected to the first housing part via the respective pivot axes.

The pivoting movements of the two housing parts can be carried out independently of each other, so that optimal illumination of objects is possible.

The respective pivot positions are designed to be self-locking. This prevents the second housing part with the functional carrier and lighting elements from being accidentally adjusted.

Preferably, the flat, hook-shaped extensions have an angular graduation. According to the invention, a pivoting movement of the respective second housing part of essentially 90° is possible.

Using the angle graduation, a corresponding lighting position can be marked and the desired position can be readjusted precisely in an easy manner.

At least the first housing part is designed as a stamped and bent part, whereby the flat, hook-shaped extensions are realized as an extension of the respective front side surface.

This means that the flat, hook-shaped projections are virtually an integral part of the first shell part.

Of course, the first housing part can also be made as an injection-molded part with integral hook-shaped extensions. The important thing, however, is that there is no need to produce separate hook-shaped extensions that then have to be connected to the respective housing part afterwards. The one-piece design simplifies the manufacturing and assembly process of the corresponding lights and reduces the associated costs.

In a further development of the invention, the stamped and bent part or a corresponding plastic injection-molded part with axle bearing has stud bolts or similar means for fastening a wiring carrier with lighting means.

The first part of the housing contains electronic components for operating the lamps.

In this respect, it is possible to divide the space between ballast modules on the one hand and lamps on the other. This means that the second housing part, which houses the lamps among other things, can be manufactured to be particularly flat.

Since the flat, hook-shaped extension is almost completely immersed in the second housing part when the respective long side of the first housing part and the respective top side of the second housing part are in an essentially 90° position, it is therefore invisible. In such a position, no swivel or pivot joint or similar mechanical device can be seen from the outside, which improves the overall aesthetic impression of lights realized in this way.

In a preferred embodiment, the longitudinal extent of the respective second housing part is greater than that of the first housing part, with the slot-shaped openings in the second housing part being located at a distance from the respective front side of the second housing part. As a result, it is not immediately apparent, both from the side view and from below, i.e. looking at the lamp side, that the lamp in question has the option of being pivoted. In this respect, too, the overall aesthetic impression of the lamp is raised to a new level.

The invention will be explained in more detail below using an embodiment and with the aid of figures.

• 1 eine Draufsicht auf eine Leuchte mit mehrteiligem Gehäusekörper, wobei eine zweiflammige Ausführung mit erkennbarem Stromschienenadapter dargestellt ist;

Here we show:

• 1 a plan view of a luminaire with a multi-part housing body, showing a two-lamp version with a visible busbar adapter;
• 2 a side view of the luminaire according to 1 , also with recognizable busbar adapter;
• 3 a bottom view of the lamp according to the 1 or 2 with indicated diffuser behind which a wiring carrier with lamps is located within the second housing part;
• 4 a luminaire according to the illustrations in accordance with the 1 to 3 in perspective view with an approx. 45° pivot position of the second housing part relative to the position of the first housing part;
• 5 a detailed representation according to the 4 with the flat, hook-shaped projections that can be seen there, which fit into the respective slots of the second housing part (see also 4 ) immersion along with angular graduation on a section of the flat, hook-shaped projections;
• 6 a representation of the lamp according to 5 , but in a 90° swivel position as shown in the 1 to 3 , whereby it is evident in this illustration that the flat, hook-shaped extensions are almost completely immersed in the interior of the second housing parts of the lamp and disappear there, and
• 7 the representation of a single-flame lamp on the basis of the multi-part housing body according to the invention in an approximately 45° winding position, again with a recognizable flat, hook-shaped extension and angular degree division.

The luminaires shown in the figures basically consist of a first housing part 1 and one or two second housing parts 2.

In the described embodiments, the first housing part 1 has a busbar connection 3 according to the prior art.

The necessary electronic components for operating the lamp, in particular a ballast or a switching device 4 for adjusting the power of the lamp, are formed in the first housing part 1. Stop buffers 5 on the second housing parts 2 serve to ensure that the opposing surfaces of the first and second housing parts 1; 2 come into gentle contact when a pivoting movement is carried out.

The particularly flat second housing parts 2 (for example see 2 ) accommodate a functional carrier (not shown) inside them. The functional carrier in turn serves to accommodate a circuit board or a similar wiring carrier, which in turn has lighting means, for example light-emitting diodes.

Towards the bottom, i.e. on the outside, the second housing part or parts 2 according to the example according to 3 provided with a translucent or opaque cover 6.

This cover 6 or the cover 6 acting as a diffuser is fixed in the respective second housing part 2 via a snap-in clamp connection.

After removing the cover 6, the wiring carrier with the light source is replaceable, which represents a significant advantage compared to other lights based on light-emitting diodes, where the light sources are fundamentally non-replaceable.

The view 1 still shows slot-shaped openings 7 in the upper side of the respective second housing part 2.

These slot-shaped openings 7 serve to accommodate flat, hook-shaped projections 8 formed on the front sides of the first housing part 1 (see, for example, the 4 , 5 and 7 ).

At the 6 There is a quasi 90° position between the respective long side of the first housing part 1 and the respective top side of the second housing parts 2.

In this position, the flat, hook-shaped extensions 8 are completely immersed via the slot-shaped opening 7 into the cavity within the respective second housing part 2 and are not visible.

The 4 and 5 now show an exemplary angle adjustment position of the second housing parts 2 relative to the position of the respective first housing part 1.

In this state, part of the flat, hook-shaped projection 8 can be seen.

This part of the hook-shaped extension 8 additionally has an angular degree graduation for the reproducible setting of the adjustment position.

This angular degree division can be designed, for example, as a line division 9.

In the same way, the pivoting of a single-lamp luminaire is 7 using the aforementioned flat, hook-shaped projections 8 in conjunction with the associated, complete mentary slot-shaped openings 7 in the second housing part 2.

In the interior of the second housing part 2, a hook end of the flat, hook-shaped extension 8, not shown in the figures, is received by an axle bearing.

This axle bearing can be inserted as a stamped and bent part into the second housing part 2 and be a component of the functional carrier.

The respective swivel axis can be designed as a screw bolt with a self-retaining swivel lock, so that the selected swivel position of the corresponding second housing parts is maintained.

In particular, based on the 1 and 2 It is understandable that the longitudinal extension of the respective second housing part 2 is greater than that of the first housing part 1, whereby the slot-shaped openings 7 in the second housing part 2 are located at a distance from the respective front side of the second housing part 2. In the case of the two-flame luminaire design, as can be seen for example from the 4 and 6 As shown, the flat, hook-shaped extensions 8 on the respective end faces of the first housing part 1 are mirror-imaged.
