Description

[0001] The invention relates to a housing for a luminaire, in particular a wall luminaire, according to the preamble of claim 1, as well as a set comprising several different housings according to the invention, as well as a luminaire comprising a housing according to the invention, as well as a set comprising several different luminaires according to the invention, as well as a method for realizing a housing, as well as a method for realizing a luminaire and a method for assembling a luminaire.

[0002] Various approaches to realizing a housing for a luminaire are known in the prior art. These approaches share the common goal of providing a robust, visually appealing housing that can be easily mounted to a building element, particularly a wall, in such a way that reliable fixation to the building element is achieved. This fixation also facilitates easier electrical connection of the luminaire components located inside the housing. Furthermore, housings known in the prior art have at least one light emission opening through which light generated by light sources located inside the housing can be emitted into the surrounding area.The present invention relates in particular to a housing for a wall light and thus to a housing suitable for mounting on a wall. Of course, in certain applications the housing can also be mounted not on a wall, but on another structural element, such as a lamppost or bollard, a bridge, or a decorative element.

[0003] It is known in the prior art to design the housing as consisting of at least two parts to provide a suitable enclosure, namely at least a mounting part and a lighting part. The mounting part forms at least one mounting section of a vertically extending mounting side, in particular the entire mounting side, of the enclosure, with which it can be attached to the building element, in particular the wall. The mounting part can thus be positioned against the building element, in particular the wall, with its mounting section and attached to the building element, in particular the wall. The mounting side of the mounting part is therefore generally designed to be suitable for attachment to the building element. The lighting part has an interior for receiving lighting components and a light-emitting side and can be attached to the mounting part and thus, by means of the mounting part, to the building element, in particular the wall.The at least two-part design allows for easy attachment of the mounting component to the building element, followed by connection of the luminaire component to the mounting component. Furthermore, an electrical cable, i.e., a power supply line, can be pre-positioned on the mounting component, which can then be electrically connected to the luminaire components located inside the luminaire component to supply power to those components.

[0004] In principle, it has proven advantageous in the prior art to provide a housing comprising a mounting part on the one hand and a luminaire part on the other, which is simplified by the manufacturability and ease of assembly of the housing. However, it has proven problematic to ensure, with such a housing design, that after the luminaire part has been fixed in the mounting part, the luminaire components inside the luminaire part remain accessible for maintenance, and that, at the same time, the housing, in its operational state when mounted on the component and the luminaire part is fixed to the mounting part, is both visually appealing and sufficiently robustly fixed to the component while also allowing suitable light emission into the surroundings through its light emission opening.

[0005] The present invention is based on the objective of providing a housing or a set of housings or a luminaire or a set of luminaires or a method for realizing a housing or a method for realizing a luminaire or a method for assembling a luminaire, with which at least one problem existing in the prior art is at least partially solved.

[0006] As a solution to the described problem, the invention proposes a housing with the features according to claim 1. The housing is suitable for use as the housing of a luminaire, in particular a wall luminaire. The housing comprises at least one mounting part and one luminaire part as housing components. In an operating state of the housing, the luminaire part is attached to the mounting part. The luminaire part can be attached to a building element, in particular a wall, by means of the mounting part. For example, the mounting part can first be attached to the building element and then the luminaire part can be attached to the mounting part. The mounting part forms at least one mounting section of a vertically extending mounting side of the housing. The mounting side designates the side of the housing that faces the building element, in particular the wall, when the housing is mounted on the wall.The mounting part can be attached to the component, particularly the wall, via the mounting section. The luminaire part has an interior for accommodating luminaire components and a light-emitting side with a light-emitting opening that is closed by a translucent cover when the housing is in operation. Preferably, the housing includes the translucent cover. The light-emitting side of the luminaire part is preferably offset, particularly angled, especially by at least 45°, particularly at least 60°, and particularly by 90°, relative to the mounting side or mounting section of the housing. The luminaire part may have at least one further light-emitting side that is angled relative to both the light-emitting side of the luminaire part and the mounting side of the housing.For example, the light-emitting side can be a vertically downward-facing underside of the luminaire part, and the other light-emitting side can be a vertically upward-facing top side of the luminaire part, and / or at least one other light-emitting side can be a side of the luminaire part pointing in a horizontal direction, for example, a front or rear side, or a side pointing away from the mounting side when the housing is in its operating state. The term "vertical" here refers to a direction along a vertical axis defined with reference to the housing in its operating state. When mounted on a component, the vertical direction preferably corresponds to the direction of the normal force acting on the ground. Every horizontal direction is perpendicular to the vertical direction.According to the proposed solution, both the luminaire component and the mounting component each have a retaining area, with the luminaire component being detachably attached to its corresponding retaining area on the mounting component. This detachable attachment makes maintenance of the housing, or of the luminaire enclosing the housing, particularly advantageous. The mounting component can remain unchanged on a building element, such as a wall, due to the detachable design, while the luminaire component can be removed from the mounting component for maintenance purposes.

[0007] In one embodiment, the holding area of ​​the luminaire part has a first hinge section and a first fixing section, and the holding area of ​​the mounting part has a second hinge section and a second fixing section. The first hinge section and the first fixing section are thus encompassed by the luminaire part, while the second hinge section and the second fixing section are encompassed by the mounting part. The first and second hinge sections can be detachably engaged to mount the luminaire part to the mounting part, thereby establishing a mounting state of the housing and forming a hinge connection between the mounting part and the luminaire part. The mounting state, like the operating state, refers to a defined arrangement of all housing components relative to one another. The arrangement of the components in the mounting state differs from the arrangement of the components in the operating state.In the assembled state, the aforementioned joint connection is formed by the engagement between the first and second joint sections. From the assembled state, the operating state can be achieved, whereby, starting from the assembled state, the luminaire part must pivot relative to the mounting part about a joint axis defined by the joint connection. The joint connection thus has the aforementioned joint axis, defining the pivotability of the mounting part and the luminaire part relative to each other to achieve the operating state from the assembled state. In the assembled state, the luminaire part and the mounting part occupy a defined angular position relative to each other, with respect to a rotation about the joint axis. Starting from the assembled state, the luminaire part and the mounting part can pivot relative to each other about the joint axis until they occupy a specific angular position, with respect to a rotation about the joint axis, which differs from the initial angular position.The first and second fixing sections can be detachably engaged at a specific angular position relative to the luminaire and mounting part, thereby fixing this angular position and realizing the operating state of the housing. In the described advantageous embodiment, the luminaire and mounting part thus occupy the specific angular position relative to each other in the operating state of the housing, and the first and second fixing sections are detachably engaged. The inventors recognized that by providing the described joint section and fixing sections, a particularly simple and robust fixing of the luminaire to the mounting part can be ensured. Furthermore, thanks to the detachable engagement between the first and second fixing sections, easy disassembly of the luminaire from the mounting part is possible, starting from the operating state.Such disassembly can be carried out, for example, by first releasing the engagement between the first and second fixing sections from the operating state, and then pivoting the luminaire part and mounting part around the joint axis until the assembly state is reached, after which, by releasing the engagement between the first and second joint sections, the luminaire part can be disassembled from the mounting part and thus removed from it.

[0008] In one embodiment, one of the fixing sections forms a locking mechanism, and the other of the fixing sections forms a locking device. For example, the first spring section formed by the luminaire part can form the locking device, and the second spring section formed by the mounting part can form the locking device. Of course, the reverse is also possible. Preferably, at least the locking mechanism has a spring. In one embodiment, both the locking mechanism and the locking device each have a spring. In another embodiment, the locking mechanism has a spring, whereas the locking device is rigid. By providing a locking mechanism and a locking device, a releasable engagement of the first and second fixing sections to fix the specific angular position can be achieved in a particularly simple and practical manner.In one embodiment, one of the locking device and locking mechanism has a recess, and the other has a projection that can be engaged in the recess. In another embodiment, at least one of the locking device and locking mechanism has a chamfer that forms a sliding surface for the other of the locking device and locking mechanism during assembly of the luminaire part to the mounting part. In another embodiment, at least one of the housing parts, i.e., at least one of the luminaire part and mounting part, has a base body. Preferably, the base body is manufactured in one piece, in particular from a metal or a metal alloy. Preferably, the base body comprises at least 80%, in particular at least 90%, and in particular at least 95% of the total mass of the respective housing part. Preferably, the base body is manufactured by die casting.In one embodiment, the locking device is encompassed by one of the housing parts, which has such a base body, wherein the locking device is integrally integrated into the base body. Preferably, the locking device is formed at least partially by a section formed in the base body by milling. In another embodiment, one of the housing parts has the aforementioned spring and a base body as described, wherein the spring is designed as a component separate from the base body and is fixed to it in such a way that it is spaced apart from a section of the housing part and is deflectable relative to this section. Preferably, the spring is encompassed by the locking device.Preferably, both housing parts each have a base body as described, wherein one of the housing parts, in particular the luminaire part, has a locking device integrally integrated into the base body as described, and the other of the housing parts, in particular the mounting part, has the spring of the locking device it encompasses in addition to its base body. By providing a spring as a separate component in front of the base body, the spring can be designed to be particularly simple and efficient. The spring is generally preferably made of a sheet metal part. It is generally preferable that the spring is made of a plate-like sheet metal piece in which, for example, recesses are provided, for instance, to ensure fastening options and / or to define the spring's elastic properties.Preferably, the detent device has the described lead-in chamfer, wherein the spring of the detent device is made of a sheet metal part, in particular a plate-shaped sheet metal piece. In one embodiment, the spring is fixed to two mounting sections, which may each be designed as a projection, of the housing part that the spring encompasses. Preferably, the mounting sections are spaced apart from each other by a certain distance, wherein the spring is fixed to the mounting sections bridging this distance and is deflectable from its rest position perpendicular to this distance. The distance is, of course, a distance in a specific direction, with deflection perpendicular to this direction preferably being ensured.Preferably, the described section, from which the spring is spaced, extends between the two mounting sections, the distance between the mounting sections being determined by the length of the aforementioned section of the housing part between the mounting sections. It has been found that fixing the spring to two mounting sections can be particularly robust and, moreover, this ensures a particularly simple guarantee of the required spring-elastic properties of the spring, even with a simple spring design.It has proven particularly advantageous to fix the spring to the base body of the housing part that encompasses the spring in such a way that the spring can be deflected in a specific direction, with the spring being guided along this direction in a linear guide formed by the housing part, in particular its base body, so that it is guided by the linear guide during deflection along this direction. This allows for a particularly advantageous design of the spring and thus a particularly reliable, releasable engagement of the fixing sections.

[0009] In one embodiment, one of the retaining areas has an opening accessible from the outside of the housing when it is in operation, through which at least one of the fixing sections can be accessed to release the angular position. For example, the opening can be designed so that a slotted screwdriver can be inserted through it from the outside. Preferably, the opening is aligned with the spring described above, so that the spring is accessible from the outside through the opening and can thus be actuated from the outside through the opening to release the engagement between the first and second fixing sections.

[0010] In one embodiment, at least one of the joint sections has at least one hook, while the other joint section has at least one retaining projection. In the assembled state, the hook engages behind the retaining projection. By providing hooks and corresponding retaining projections, a joint connection can be implemented particularly easily, which is sufficiently robust and ensures easy pivoting of the luminaire part and the mounting part relative to each other from the assembled state. Preferably, one of the hooks and retaining projections has a rounded section against which the other of the hooks and retaining projections rests in the operating state. This ensures particularly advantageous easy alignment of the luminaire part and the mounting part relative to each other.

[0011] In one embodiment, one of the retaining areas surrounds the other retaining area around a horizontal axis. This advantageously ensures both protection of the other retaining area and an aesthetically pleasing finish. Preferably, one retaining area has the described opening through which at least one of the fixing sections is accessible for releasing the angular position. Preferably, the luminaire component has this one retaining area. This allows the luminaire component to form a significantly larger portion of the housing's exterior surface when mounted on a component.Preferably, in a state of the housing in which the housing is in its operating state and mounted on a flat, vertically extending component, the mounting part forms less than 1%, in particular less than 0.5%, and in particular no section at all of the outer surface of the housing that is accessible from the outside in this state. It is naturally assumed that the component extends in a vertical direction and in a horizontal longitudinal direction, and that, in the state mounted on the component, the housing lies at least partially, and in particular completely, within the extension area of ​​the component in both the vertical and longitudinal directions. Generally preferably, the housing is designed without screws on its outer surface, which is accessible from the outside when the housing is mounted on a flat, vertically extending component.This ensures easy assembly and disassembly of the housing on the component, as well as a visually appealing appearance of the housing when assembled. The assembled state naturally refers to the mounting part being fixed to the component and the luminaire being fixed to the component by means of the mounting part. Preferably, the exterior surface accessible from the outside when assembled is completely formed by the luminaire and all, in particular exactly one, cover(s) attached to the luminaire.

[0012] In one embodiment, the mounting part has a trough-like section with a trough bottom and a side wall surrounding the trough bottom, wherein the trough-like section of the mounting part forms the mounting section of the housing's mounting side. Preferably, the mounting section is at least partially, and in particular completely, formed by the side wall. Preferably, at least one opening for an electrical cable is provided in the trough bottom. Due to the provision of the trough-like section, which forms the mounting section of the housing and with which the housing rests against the component when mounted on the component, a receiving volume is formed in the mounted state, which can serve to receive components, for example, electrical cables, screw heads, or the like.A generally preferred design is a receiving space defined by the base and side wall of a trough to accommodate a section of an electrical cable. Preferably, when mounted on the component, the electrical cable extends through the opening in the base of the trough towards the luminaire section, particularly into the interior of the luminaire section. Preferably, retaining lugs are provided on the base of the trough and / or on the side wall to guide the electrical cable within the receiving space. These retaining lugs can form an arrangement through which the electrical cable can be guided, thus defining its position within the receiving space. Providing the trough-like section, and especially the receiving space defined by it, can significantly simplify the mounting of the housing or a luminaire enclosing the housing to the component.

[0013] In one embodiment, each of the holding areas has a contact section that extends in a horizontal longitudinal direction and in a vertical direction. When the housing is in operation, the holding areas of the mounting part and the luminaire part press against each other directly or indirectly via a seal. This ensures a particularly reliable fixation of the luminaire part and the mounting part to each other, and in particular a seal between the mounting part and the light source.

[0014] In one embodiment, the mounting section of the luminaire part completely encloses an access opening to the interior of the luminaire part. After the luminaire part has been detached from the mounting part, starting from the operating state, the interior of the luminaire part is thus accessible through this access opening. This can be particularly advantageous for servicing luminaire components located inside the luminaire part. Preferably, the mounting section of the mounting part also completely encloses the access opening when the housing is in its operating state. This ensures that the access opening is sealed to the environment when the housing is in operation, but that elements from the mounting part, such as at least one electrical cable, can pass through the access opening into the interior of the luminaire part.

[0015] In one embodiment, to drain water that has accumulated on the top side of the housing, at least one of the system sections extends obliquely to the longitudinal and vertical directions along at least 70% of its longitudinal extent and / or is covered by a roof-like projection extending obliquely to the longitudinal and vertical directions along at least 70% of its longitudinal extent. In another embodiment, to drain water that has accumulated on the top side of the housing, at least the seal extends obliquely to the longitudinal and vertical directions along at least 70% of its longitudinal extent and / or is covered by a roof-like section extending obliquely to the longitudinal and vertical directions along at least 70% of its longitudinal extent.Providing a sloping top surface, as described above, on at least one of the system sections and / or at least the seal and / or at least a roof-like section has proven particularly advantageous, since this effectively prevents water from remaining on the top surface of the system sections or the seal and thus prevents water from penetrating the interior of the luminaire. Preferably, to drain away water that has accumulated on the top surface of the housing, at least one of the system sections and / or at least the seal and / or at least the aforementioned roof-like section slopes diagonally across its entire top surface to both the longitudinal and vertical directions.

[0016] In one embodiment, the light-emitting side of the luminaire forms at least a section of the underside of the housing. The light-emitting opening is thus located on the underside of the housing. After the housing, which contains the luminaire, has been mounted to the component, the luminaire can emit light vertically downwards through the light-emitting opening. Preferably, in the operating state of the housing, the light-emitting opening is spaced apart from the mounting side. This allows light to be emitted through the light-emitting opening particularly advantageously when the housing is mounted on the component, where the housing is attached to the component via the mounting section. In another embodiment, the luminaire has a further light-emitting side that forms at least a section of the top of the housing and on which a further light-emitting opening is provided.A luminaire encompassing the housing can thus be designed for both direct and indirect illumination, in that the luminaire emits light downwards through the light emission opening and upwards through the additional light emission opening. Preferably, in the operating state of the housing, the additional light emission opening is spaced away from the mounting side. More generally, preferably, the light emission side and / or the additional light emission side extend substantially horizontally. For example, the light emission side and / or the additional light emission side can each have an angle of < 45°, in particular < 30°, in particular < 20°, to the vertical direction, averaged over their entire horizontal extent. The light emission side and / or the additional light emission side thus extend predominantly horizontally over their entire extent.

[0017] In one embodiment, the mounting part includes a pressure equalization device that is connected to the interior of the luminaire part during operation. The provision of a pressure equalization device is generally known in the prior art. Such a pressure equalization device ensures that, in the event of a pressure increase / decrease within a housing caused by heating / cooling of the volume contained within the housing, particularly where light sources generate heat / the interior cools down after the light sources are switched off, pressure equalization can occur between the interior of the housing and the environment surrounding the housing. It is known that such a pressure equalization device can be designed in such a way that it does not impair the sealing of the interior; for example, a pressure equalization device can include a suitable membrane and / or channel-like air ducting.The present invention has revealed that providing the pressure equalization device on the mounting part offers particular advantages. On the mounting part, the pressure equalization device can not only be arranged in a way that conceals the housing of the luminaire from view, but it can also be easily implemented and protected when the housing is mounted on a component, for example, by a retaining area for the luminaire part, as described above. During operation, the pressure equalization device is, of course, connected to the interior of the luminaire part via a gas supply; for example, the pressure equalization device can be connected to the interior of the luminaire part via the access opening described above.The assembly preferably features the described trough-like section, with the pressure equalization device being located at the bottom of the trough, such that the pressure equalization device includes an opening provided in the bottom of the trough. By locating the pressure equalization device at the bottom of the trough, it can be particularly well protected and concealed from view, and furthermore, sufficient space can be provided within the volume defined by the bottom and side walls of the trough for its implementation.

[0018] In one embodiment, the luminaire component and / or the mounting component has a base body that is manufactured in one piece. For example, the base body can be made of a metal or a metal alloy, particularly by die casting. In one embodiment, the base body forms at least the majority, and in particular at least 90%, of the outer surface of the respective housing component that is accessible from the outside during operation, and in particular completely. The term "outer surface" refers to the surface that is accessible to a person from the surroundings of the housing during operation. It is particularly preferred that the housing can be mounted on a flat structural element extending vertically and longitudinally, in particular on a flat wall extending vertically and longitudinally, by placing the mounting component with its mounting section against the structural element or the wall and attaching it to the wall.Preferably, in such a mounted state of the housing, in which the housing is in its operating state, the entire outer surface of the housing is formed at least predominantly by the luminaire part and / or jointly by the luminaire part and all covers provided on it. Preferably, the mounting parts in such a mounted state form less than 1%, and in particular no section, of the outer surface of the housing. Preferably, the mounting part in such a mounted state is completely concealed by the luminaire part. Generally preferred, the housing is designed without screws on its outer surface, which is accessible from the outside when mounted on a flat, vertically extending component.

[0019] In one embodiment, the cover and a surrounding rim of the luminaire part are bonded together and / or connected by an interlocking tongue-and-groove joint. The tongue-and-groove joint can be achieved, for example, by the luminaire part having a groove and the cover a corresponding tongue, or by the cover having a groove and the luminaire part a corresponding tongue. The interlocking tongue-and-groove joint or the bonding ensures a particularly simple and airtight fixation of the cover to the luminaire part.Preferably, all covers arranged on the luminaire part, which each close a light emission opening or further light emission opening of the luminaire part in the operating state of the luminaire, are advantageously connected to the luminaire part, in particular to the base body of the luminaire part, as explained.

[0020] In one embodiment, the luminaire part has a fixing device on its inner side for securing luminaire components. For example, the fixing device can be designed to correspond to a luminaire component holder to which the luminaire components are attached. Providing the fixing device on the inner side of the luminaire part allows for particularly convenient fixing of the luminaire components within the interior of the luminaire part. It should be noted that the inner side is a side of the luminaire part that defines the interior of the luminaire part. Preferably, the inner side runs vertically.This allows for the particularly advantageous fixing of lighting components in such a way that the lighting components, designed as light sources, can emit light vertically from the housing into its surroundings as undisturbed as possible, for example, via a horizontally extending cover or through a horizontally extending light emission opening. Preferably, the inner surface is designed as a vertically extending interior between the underside and the top of the lighting component; more preferably, the interior surface extends from the underside to the top of the lighting component. Thus, the interior surface preferably connects the underside and the top along the vertical direction. This allows for easy access to the interior surface for fixing the lighting components.

[0021] In one embodiment, the fixing device is accessible from the light emission aperture and also from an access opening formed by the holding area. In the operating state of the housing, the access opening preferably faces the mounting side of the housing. More preferably, in the operating state of the housing, the access opening faces the mounting part.By making the fixing device accessible from both the light emission opening and the access opening, it is possible, for example, during the implementation of a luminaire, to insert the housing, a luminaire component and / or a luminaire component holder with several luminaire components through the light emission opening into the interior of the luminaire part and then fix it to the luminaire part, after which, for example, the light emission opening can be closed by a cover that is permanently connected to the luminaire part, after which the fixing device or the luminaire components fixed to it remain accessible through the access opening.For example, the access opening can be concealed by the mounting part during operation. However, after the luminaire part is removed from the mounting part, the access opening becomes accessible, allowing maintenance of the luminaire components that are fixed to the fixing device. The fixing device preferably includes a guide rail designed as a linear guide extending along a vertical axis. This can greatly simplify the targeted insertion of luminaire components along the guide device or guide rail into the interior of the luminaire part. For example, the guide rail can have several rail sections, each arranged perpendicular to the vertical direction and each extending vertically, thus enabling particularly advantageous guidance of luminaire components or a luminaire component holder.

[0022] The invention further relates to a set comprising at least two housings according to the invention, which are designed differently from one another. In one embodiment, the set has a first and a second housing, wherein the lighting components of the first and second housings are each compatible with the mounting component of the other housing. The term "compatible" means that the mounting component of each housing can interact with, or is designed to correspond to, the lighting component of the other housing, as explained with reference to embodiments of housings according to the invention. Preferably, the lighting component of the first housing is closed at its top and has its light emission opening at its bottom, whereas the lighting component of the second housing has its light emission opening at its bottom and its other light emission opening at its top.The set thus ensures the simple and cost-effective provision of different housings for various applications: Using an identically designed mounting part, a different luminaire can be created by combining the mounting part with either the luminaire section of the first housing or the luminaire section of the second housing. The first housing allows for a purely direct luminaire, while the second housing allows for a luminaire with both direct and indirect luminaire emission. In one embodiment, the set includes a third and a fourth housing, which differ in both their mounting part and their luminaire section. It should be noted that the numbering "first, second, third, fourth" serves only to distinguish the housings conceptually.The set can, for example, comprise only the housing described herein as the third or fourth housing, or only the first and second housings. Regarding the third and fourth housings, it is provided that the light emission openings of the third and fourth housings each have an identical horizontal distance to their respective mounting sides. The invention is based on the understanding that, although this allows for the provision of luminaire components with different properties, the identical spacing of their light emission openings from the respective mounting side of the housing enclosing them allows the use of identical optical elements in each luminaire component, since it can be assumed that the light emission openings, and in the application case, i.e.,When each housing is used as part of a luminaire that emits light, a comparable light emission characteristic can be achieved with respect to the mounting side of the respective housing. For example, the luminaire part of the third housing can have a rounded horizontal cross-section, such as a circle or ellipse, whereas the luminaire part of the second housing can have a square or rectangular horizontal cross-section. It should be noted that depending on the design of the luminaire part or its geometric shape, different internal dimensions result, and thus different space requirements for the luminaire components or optical elements to be arranged within it.The invention is based on the understanding that it is particularly advantageous to ensure that, even when the luminaire components are modified, the distance between the light emission opening and the mounting side of the respective housing remains at least substantially the same. It should be noted that this distance refers to a distance along a transverse direction, perpendicular to the vertical direction and perpendicular to a longitudinal direction, when the housing is mounted on a component that is planar in both the vertical and longitudinal directions. It has proven particularly advantageous to design the luminaire components of the third and fourth housings differently such that their extension lengths in this transverse direction differ, while the distance between their light emission openings and their mounting sides remains the same.This allows for consideration of different housing characteristics, such as their different horizontal cross-sections as explained, without requiring any modification of optical elements in the luminaire part of the respective housing.

[0023] The invention further relates to a luminaire comprising a housing according to the invention. The luminaire has at least one luminaire component. At least one light source is provided as a luminaire component; furthermore, for example, at least one additional light source, at least one electrical cable, at least one radio module, and / or at least one control gear may be provided. In an operating state of the luminaire, the at least one luminaire component(s) are arranged in the interior of the luminaire housing and fixed relative to it.

[0024] In one embodiment, the luminaire has an adjustment device that allows the position of the light source to be changed while it remains unchanged within the interior of the luminaire and fixed relative to it. This can apply to multiple light sources when several are provided. Because the light source's position can be changed thanks to the adjustment device, while it remains unchanged within the interior of the light source and securely fixed to it, the luminaire's beam characteristics can be finely adjusted. In one embodiment, the adjustment device allows the position of the light source to be changed relative to an optical element of the luminaire. In another embodiment, the adjustment device allows the position of the light source to be changed together with an associated optical element.It is generally preferred that the beam angle of the light source be altered by a change in position of the light source produced by the adjustment device, over which the luminaire emits all the light originating from the light source. For example, such a change in position can be produced by the adjustment device such that the beam angle, which is a defined solid angle, is shifted horizontally or tilted relative to the vertical axis, in particular by at least 5 cm horizontally and / or tilted by at least 1°, in particular at least 2°, in particular at least 3° relative to the vertical axis. The beam angle is defined as a spatial light distribution and thus as a three-dimensional shape emitted by the luminaire in the form of light rays due to the light produced by the light source. The position of this shape in space can be changed as described above by the change in position.It is particularly advantageous that the adjustment mechanism is accessible from the outside while the luminaire is in operation. This allows for fine-tuning of the light beam angle, the angle over which the luminaire emits light based on the light generated by the light source, even after the luminaire has been installed, i.e., with the housing mounted. It should be noted that the light source can be, for example, a single LED or an LED array.

[0025] In one embodiment, the luminaire has a luminaire component holder that is fixed to an inner surface of the housing and to which the luminaire components, or at least one luminaire component, are attached. In another embodiment, at least some of the luminaire components are accessible through an access opening formed by the mounting area of ​​the luminaire part. In yet another embodiment, when the luminaire is in operation, the luminaire components, together with the luminaire component holder, form a luminaire component assembly that, to achieve the operating state of the luminaire, can be inserted from the outside through the light emission opening into the interior of the housing, but cannot be removed from the interior of the housing through the access opening once the luminaire is in operation. Preferably, the luminaire component assembly can be inserted into the interior of the luminaire part through the light emission opening, but not through the access opening.This offers the distinct advantage that the lighting component assembly can be pre-assembled as comprehensively as possible and then inserted as a complete assembly through the light emission opening into the interior of the luminaire housing. At the same time, the access opening does not need to be excessively large, thus simplifying, for example, covering the access opening with the mounting component when the luminaire is in operation. However, the lighting components enclosed within the assembly remain accessible through the access opening for maintenance purposes. Preferably, the light emission opening is permanently sealed by the cover when the luminaire is in operation. This ensures a particularly aesthetically pleasing and effective seal between the cover and the luminaire housing.Generally preferred, starting from the operating state after disassembly of the luminaire part from the mounting part, is that the access opening of the luminaire part is accessible and that at least one of the luminaire components can be detached from the other components of the luminaire component arrangement through the access opening and removed from the interior of the luminaire part through the access opening.

[0026] In one embodiment, the luminaire component holder is designed as a carriage corresponding to the fixing device of the luminaire part, wherein the fixing device and the luminaire component holder together form a linear guide arrangement, and, in the operating state of the luminaire, the luminaire component holder is fixed in position relative to the fixing device within the interior. By forming a linear guide arrangement with the luminaire component holder and the fixing device, the luminaire component holder with the luminaire components arranged thereon, i.e., in particular the luminaire component arrangement, can be inserted into the interior of the luminaire part particularly easily and precisely, whereas the fixed position during operation ensures reliable and damage-preventing fixation of the luminaire component holder and thus of the luminaire components arranged or fixed to it.Preferably, the fixing device and / or the luminaire component holder is wedge-shaped, so that during insertion of the luminaire component holder with its attached components into the interior of the luminaire part, the wedge shape ensures a guided alignment of the luminaire component holder relative to the luminaire part. The wedge shape thus forms at least one inclined sliding surface that runs obliquely to the insertion direction defined by the fixing device and the luminaire component holder, along which the luminaire component holder is to be inserted into the interior of the luminaire part due to the interaction with the fixing device, the insertion direction preferably being vertical.

[0027] In one embodiment, the luminaire has a connection bracket that is fixed to the mounting part and to which a plug connector is fixed. A corresponding plug connector is fixed to the luminaire part and is connected to at least one luminaire component located inside the luminaire part. The plug connector can be connected to an electrical supply cable running outside the housing on the mounting side, and the corresponding plug connector can be attached to the plug connector to supply power to the at least one luminaire component before the luminaire part is detachably fastened to the mounting part. The electrical supply cable can, for example, be the electrical cable described herein, which passes through the feed-through opening provided in the base of the mounting part.By incorporating a mounting bracket with an integrated plug connector, and by allowing the corresponding plug connector to be attached to the mounting bracket (similar to standard plug-and-socket connectors), the luminaire can be mounted to a building component in a particularly simple manner. Such mounting includes not only mechanical fastening but also connecting an electrical supply cable to the luminaire components that require power. For example, the mounting bracket can first be attached to a building component, and the plug connector attached to the mounting bracket can then be connected to the supply cable. Afterward, the corresponding plug connector is attached to the mounting bracket, and finally, the luminaire component is detachably fastened to the mounting bracket.The connection bracket, mounting part, and luminaire part are specifically designed to align with each other in such a way as to ensure the detachable connection of the mounting part and the luminaire part as described in the embodiments of the invention. Thus, for example, an installer can first mount the mounting part to a component and connect the plug-in device using only the supply cables. Then, holding the luminaire part with one hand and using the other hand, attaching the corresponding plug-in device to the mounting part, the installer connects or fastens the luminaire part to the mounting part as described in the embodiments of the invention.The corresponding plug-in device is connected, for example, via an electrical cable to light sources and / or a control gear as lighting components, whereby in the described method for mounting a luminaire on a component, the corresponding plug-in device is first plugged onto the plug-in device and then the electrical cable is stowed in the interior of the luminaire part while the luminaire part is being attached to the mounting part.

[0028] The invention further relates to a set comprising several luminaires according to the invention. The set includes at least a first and a second luminaire, which have different housings. The housings of the first and second luminaires each have a fixing device for fixing the luminaire component holder of the respective luminaire, wherein the luminaire component holder of the first and the second luminaires are each compatible with the fixing device of the other of the first and second luminaires. Thus, the luminaire component holder of the first luminaire can be fixed to the fixing device of the second luminaire as in the embodiment of the invention, and vice versa.This enables particularly cost-effective production of luminaires, since a luminaire component holder can be used to realize different luminaires due to its property corresponding to the fixing devices of different luminaires, thereby reducing manufacturing and storage costs.

[0029] The invention further relates to a method for mounting a luminaire comprising a housing with a mounting part and a luminaire part, wherein the mounting part forms at least one mounting section of a vertically extending mounting side of the housing, and wherein luminaire components comprising at least one light source are arranged in an interior space of the luminaire part. In the method according to the invention, the mounting part with the mounting section is attached to a building element, in particular to a wall, and the luminaire components are connected to an electrical supply cable provided on the building element outside the housing, and the luminaire part is detachably attached to the mounting part.As explained in the descriptions of embodiments of a luminaire according to the invention, the mounting part can, for example, first be mounted on a component and the electrical supply cable attached to a plug connector fixed to the mounting part, after which the corresponding plug connector is attached to the mounting part and the luminaire part is fastened to the mounting part. Alternatively or additionally, the luminaire part can be fastened to the mounting part by first establishing a hinge connection between the luminaire part and the mounting part, and then pivoting the luminaire part relative to the mounting part until a specific angular position is reached, and this angular position is fixed.

[0030] The invention further relates to a method for realizing a luminaire comprising a housing which includes a mounting part and a luminaire part, wherein the mounting part forms at least one mounting section of a vertically extending mounting side of the housing with which it can be attached to a building element, in particular a wall, and wherein the luminaire part has an interior space for receiving luminaire components and a light emission side on which a light emission opening of the luminaire part is provided, which is closed by a translucent cover in the operating state of the housing.In the method according to the invention, in a first step, lighting components are inserted through the light emission opening into the interior and fixed to the lighting part within the interior. In a second step, a cover for closing the light emission opening is permanently attached to the lighting part, so that the lighting components can no longer be removed from the interior of the lighting part via the light emission opening. For this purpose, a lighting component holder, as described in the embodiment of a luminaire according to the invention, can be used, for example.In particular, after the luminaire has been installed, maintenance of the luminaire can be carried out, whereby at least one of the luminaire components fixed inside the luminaire part is detached from the luminaire part through an access opening in the luminaire part, after the luminaire part has been disassembled from the mounting part, and is removed from the interior of the luminaire part through the access opening and led outwards.

[0031] The invention further relates to a method for realizing a housing for a luminaire, in particular a wall luminaire. The housing comprises, as housing parts, a mounting part and a luminaire part, which can be attached to a building element, in particular a wall, by means of the mounting part, wherein the mounting part forms at least one mounting section of a vertically extending mounting side of the housing, and wherein the luminaire part has an interior space for receiving luminaire components and a light-emitting side on which a light-emitting opening of the light source is provided, which is closed by a translucent cover when the housing is in operation. The luminaire part has a retaining area by which it can be detachably attached to a corresponding retaining area of ​​the mounting part.In one embodiment of the method according to the invention, a pre-base body of the luminaire component is manufactured by metal die casting, and the pre-base body is subsequently machined to create a base body of the luminaire component, specifically to implement a locking device, a hinge section, and / or a light emission aperture of the luminaire component. In one embodiment, the pre-base body already has the light emission aperture of the luminaire component, with the machining process creating a further light emission aperture in the pre-base body, thus realizing the base body. The machining can be carried out, for example, by milling or turning. In another embodiment, a base body of the assembly component is manufactured, in particular by metal die casting, and a spring for implementing a locking device is then fixed to the base body of the assembly component.

[0032] The various solutions according to the invention may each have features in embodiments that are described here in relation to other embodiments or to embodiments known from the prior art. In particular, embodiments of a method according to the invention may have features that are apparent to a person skilled in the art from the explanation of devices according to the invention or from the prior art.

[0033] The invention is explained in more detail below with reference to seven figures and exemplary embodiments.

[0034] They show: Figure 1 : various schematic diagrams showing different views of an embodiment of a luminaire according to the invention; Figure 2 : various schematic diagrams showing different views of an embodiment of a luminaire according to the invention; Figure 3: in various schematic diagrams showing views of components of an embodiment of a luminaire according to the invention; Figure 4 : in various schematic diagrams showing views of components of an embodiment of a luminaire according to the invention; Figure 5 : in various schematic diagrams showing views of components of an embodiment of a luminaire according to the invention; Figure 6 : in various schematic diagrams showing views of components of an embodiment of a luminaire according to the invention; Figure 7 : in various schematic diagrams showing views of components of an embodiment of a luminaire according to the invention.

[0035] In Figure 1 comprehensive the Figures 1a and 1bFigure 1 shows an embodiment of a luminaire 1 according to the invention in various schematic diagrams and perspective views. The illustrated embodiment of a luminaire 1 according to the invention is designed as a wall luminaire. The luminaire 1 has a housing comprising a mounting part 3, a luminaire part 2, and a cover 4. The luminaire 1 has a rear side which is Figure 1b as can be seen, as well as a front side facing away from the back side, and which is in Figure 1aThe rear side is designed as the mounting side of the luminaire 1. The luminaire 1 is designed to be mounted with its mounting side onto a building element, in particular a wall, which extends in a vertical direction Z and a longitudinal direction X, such that it abuts the building element, in particular the wall, with a mounting section formed by the mounting part 3. In this mounted state of the luminaire 1, the front is spaced from the mounting side in the transverse direction Y, and with respect to the longitudinal direction X, the luminaire 1 is bounded by two diverging longitudinal sides that run between the front and rear sides. In addition, the luminaire 1 has a top surface which is located in the Figures 1a and 1bThe figure shows a top surface and a bottom surface, the vertical extent of which is limited by the top surface on one side and the bottom surface on the other. While the top surface of the luminaire 1 is essentially formed by the closed top surface of the luminaire part 2, the bottom surface of the luminaire 1 is essentially formed by the closed bottom surface of the cover 4.

[0036] In Figure 2 comprehensive the Figures 2a and 2b Another embodiment of a luminaire 1 according to the invention is shown in two different perspective views, in Figure 2a in an oblique view from below, in Figure 2b in an oblique view from above. The luminaire of the embodiment according to Figure 2 differs from the luminaire of the embodiment according to Figure 1 essentially by the fact that its cover 8 is designed differently than the cover 4 of the luminaire 1 according to Figure 1and that it has a further cover 8 which forms at least a predominant part of its upper surface. While the luminaire part 2 of the embodiment according to Figure 1 Thus, having only one light emission side, namely its underside, and only one light emission opening which is closed by the cover 4, the luminaire part 2 of the luminaire 1 has according to Figure 2 The luminaires have two light emission sides, namely the top and bottom, each with a light emission opening that is closed by a cover 8. The luminaires 1 according to Figure 1 and Figure 2 They therefore have different luminaire parts 2 and each has a mounting part 3. The mounting part 3 of the luminaire 1 according to Figure 1 is in Figure 1b to recognize, while the mounting part 3 of the luminaire 1 according to Figure 2not shown. In principle, both luminaires 1 can have the same mounting part 3. At a minimum, each luminaire 1 can have a mounting part 3 that is compatible with the luminaire part 2 of the other luminaire 1, so that the luminaire part 2 of each luminaire 1 can be attached to the mounting part 3 of the other luminaire 1 in the same way as the luminaire part 2 of each luminaire 1 can be attached to the mounting part 3 of each luminaire 1. Since these properties of the luminaire 1 relate to the properties of its housing, this is naturally also the case for different housings, which may differ at least in their luminaire part and, in particular, in their mounting part. The luminaire parts 2 of the luminaires 1 according to Figure 1 and Figure 2 As explained, they differ in that the luminaire part 2 of the housing of the luminaire is designed according to Figure 1its upper surface is closed, whereas the luminaire part 2 of the luminaire 1 according to Figure 2 It has a further light emission opening on its upper side. In the present case and according to the invention, the luminaire parts 2 are advantageous as shown in the Figure 1 and 2 shown, manufactured from an identically designed pre-base body which already has a light emission opening on its underside, wherein the pre-base body, as generally explained here, can be manufactured, for example, by means of metal die casting, and wherein the further light emission opening of the luminaire part 2 according to Figure 2 is produced by milling in the pre-base body.

[0037] In Figure 3 comprehensive the Figures 3a , 3b , 3c , 3d and 3e Various components of an embodiment of a luminaire 1 according to the invention are schematically represented in different schematic diagrams and different views. Figure 3This serves to explain the interaction of the luminaire part 2 and the mounting part 3 of an embodiment of a luminaire according to the invention, as well as to explain the mountability of a luminaire 1 according to the invention on a structural element, in particular a wall, which extends horizontally in the vertical direction Z and longitudinal direction X. The explanations concerning the luminaire 1 are, of course, applicable to the explanations concerning the housing of the luminaire 1. The interaction of the luminaire part 2 with the mounting part 3 of the embodiment according to Figure 3 is analogous to the interaction of the luminaire part 2 and mounting part 3 of the embodiment according to Figure 1 , whose lighting part 2 and mounting part 3 in Figure 1b are depicted. As can be seen from the overall view of the Figures 1b and 3As can be seen, the mounting part 3 has a vertical direction indicator 391, 392 on its side facing the mounting side of the housing, or on its side forming at least a part of the mounting side, and on its side facing away from the mounting side, wherein the luminaire part 2 has a vertical direction indicator 29 corresponding to the vertical direction indicator 391, 392 on its side facing the mounting side, or on its side forming at least a part of the mounting side. Providing a vertical direction indicator on the mounting part 3 and on the luminaire part 2 is generally advantageous according to the invention.

[0038] The vertical direction indicator is information understandable to a person skilled in the art regarding the orientation of the luminaire with respect to the vertical direction Z, i.e., an indication of which side of the housing is the top and which side is the bottom. For example, the vertical direction indicator 391, 392, or the corresponding vertical direction indicator 29, may be in the form of an arrow and / or a label. It is essential that the vertical direction indicator 391, 392, and the corresponding vertical direction indicator 29 provide mutually corresponding information to a person skilled in the art; in particular, they may provide identical information or be identically designed.The provision of the vertical direction indicators 391, 392 and the corresponding vertical direction indicator 29 is generally particularly advantageous according to the invention, since a person skilled in the art can intuitively align the mounting part 3 correctly when mounting it on a building element, in particular a wall, and can then easily align the luminaire part 2 directly with each other when mounting it on the mounting part 3. Figure 3aMounting part 3 and luminaire part 2 are shown with their sides facing each other in the operating state of the housing and the luminaire 1, respectively. It can be seen that mounting part 3 and luminaire part 2 each form a holding area, the holding area of ​​which has a circumferential section 20 that completely encloses the holding area of ​​mounting part 3, a horizontally circumferential axis, in this case an axis in the transverse direction Y. This effectively protects mounting part 3 when the luminaire 1 or its housing is mounted on a component, particularly a wall, and also advantageously creates a seal between mounting part 3 and luminaire part 2.In the operating state of the housing, and likewise in the operating state of the luminaire 1 encompassing the housing, mounting part 3 and luminaire part 2 each have a contact section in contact with each other and press against each other, whereby the contact is only indirect, namely indirectly via a seal 5. The contact sections 25, 35 are each designed in a ring-like form and extend in the longitudinal direction X and vertical direction Z, which is generally advantageous according to the invention. The contact sections are encompassed by the respective holding area of ​​mounting part 3 and luminaire part 2 and enclose an access opening of the luminaire part 2 all around, which is located in . Figure 3 This can be seen. Likewise, in the operating state, the seal 5 completely surrounds the access opening. In the 3D and 3E figures The interaction of system sections 25, 35 and seal 5 is shown schematically in a simplified manner. In the 3D and 3E figuresThe seal 5 is shown overlapping with the light part 2, which is of course not the case in practice; rather, due to the pressed-in connection of the system sections 25 and 35, the seal 5 is compressed against each other by the part that is in the 3D and 3E figures as shown overlapping with the lighting part 2. From the overall view of the Figures 3a and 3c in combination with the embodiment shown in Figure 1bAs shown, the mounting part 3 has a trough-like section comprising a trough base 30 and a side wall 301 surrounding the trough base. A pressure equalization device 32 is provided on the trough base, as are feedthrough openings 37 for routing an electrical cable through the trough base. The feedthrough openings 37 are each designed as watertight sealed feedthrough openings, and the pressure equalization device 32 is similarly designed as a watertight equalization device. Furthermore, it is evident that the mounting part 3 forms a mounting section for the luminaire 1 or its housing, which is formed by elongated holes 361, 362 surrounding edges and by support sections 363.With this assembly section, the mounting body 3 can be mounted against a flat component extending in the vertical direction Z and longitudinal direction X, as described above. The elongated holes 361, 362 are, advantageously according to the invention, offset from one another and aligned in directions perpendicular to each other. In this case, the first elongated hole 361 is aligned in the vertical direction, the second elongated hole 362 in the longitudinal direction X. The elongated holes 361, 362 extend with a greater length in the direction in which they are aligned than in the direction perpendicular to them.Due to the provision of these two elongated holes 361, 362, which are aligned perpendicular to each other, the luminaire 1 or the mounting part 3 or its housing can be particularly advantageously first mounted with a play in the longitudinal direction X and vertical direction Z on a building element, in particular a wall, and subsequently aligned in a fine alignment, after which the system section is pressed against the building element, for example by means of screws which are passed through the elongated holes 361, 362 and in particular through through openings provided in the support sections 363.

[0039] From the overall view of Figures 3a and 3bIt is evident that, in the operating state of the luminaire, sections 25 and 35 and the seal 5 each run obliquely to the longitudinal and vertical directions on their upper surfaces. It should be noted here that the vertical, longitudinal, and transverse directions are defined with reference to the luminaire housing itself or to the luminaire 1 itself, and that, for example, when the luminaire 1 is mounted on a structural element, the vertical direction can advantageously be aligned parallel to the normal force acting on the ground. The beveled course of the seal 5 is shown in Figure 3bThe details are explained below. The seal 5 has an upper end 50 on its upper surface, from which at least one inclined section 51, 52, 53 extends downwards and laterally at an angle to the longitudinal direction X and to the vertical direction Z, which is generally advantageous according to the invention. This inclined design of the seal, and in particular the inclined design of the contact sections 25, 35, effectively prevents water that gets onto the seal 5 or the contact sections 25, 35 from the upper surface of the luminaire 1 or its housing from remaining there; instead, such water is effectively drained away due to the inclined design of the upper surface of the seal or contact sections.

[0040] From the overall view of Figures 3a , 3c , 3d and 3e It is also evident how, in the embodiment according to Figure 3The luminaire part 2 is to be attached to the mounting part 3. The luminaire part 2 has a first joint section 23, and the mounting part 3 has a second joint section 33. In addition, the luminaire part 2 has a first fixing section 21 and the mounting part 3 has a second fixing section 31.When the luminaire part 2 is mounted on the mounting part 3, after the mounting part has been fixed to a flat component, in particular a flat wall, the luminaire part 2 can first engage its first joint section 23 with the first joint section 33 of the mounting part 3, thereby creating a joint connection with a joint axis. The luminaire part 2 can then be pivoted relative to the mounting part 3 about this axis until a specific angular position is reached, in which the first fixing section 21 engages with the first fixing section 31, thus securing the specific angular position. In the operating state of the housing or the luminaire 1, the fixing sections 21 and 31 form a snap-fit ​​connection, whereas the joint sections 23 and 33 form the joint connections in both the operating and the mounted state of the housing.The assembly state is reached as soon as the joint sections 23 and 33 are engaged with each other. In this case, the first joint section 23 is designed in the form of hooks, and the second joint section 33 is designed as a retaining projection, the second joint section 33 having rounded sections 330 against which the hooks and the first joint section 23 bear in the operating state. The first fixing section 21 is designed as a projection with a leading-edge chamfer, whereas the second fixing section 31 comprises a spring designed as a plate-like sheet metal section in which a recess 310 and a guide lug 311 are provided. The spring is attached to two mounting sections 32 of the assembly part 3, which are designed as projections, and extends from its position in... Figure 3aThe rest position shown is deflectable, while from the assembled state it slides along the lead-in chamfer of the projection 21 to reach the operating state, which is generally required according to the invention. In the operating state, the projection 21 engages in the recess 310 of the spring of the second fixing section, as shown in Figure 3eAs shown. Starting from the operating state, the spring can be deflected by inserting a tool, for example a slotted screwdriver, through the opening 22 from the outside and pressing it against the spring, the opening 22 being located in the holding area of ​​the luminaire part 2. During the deflection described above, the spring is guided by its guide lug 311 relative to the mounting part 3, both during the deflection from the operating state to release the detent connection between the detent device and the detent assembly, or between projection 21 and recess 310, and during the deflection from the assembly state to reach the operating state.

[0041] From the overall view of Figures 3a and 3cIt is further evident that mounting part 3 and luminaire part 2 each have lateral lead-in chamfers 28, 38 on their outer surfaces, which facilitate easy sliding against each other during the mounting of the luminaire part 2 on the mounting part 3. These lead-in chamfers 28, 38 are provided on the holding areas of the luminaire part 2 and mounting part 3, in particular at least partially on the section 20 of the holding area of ​​the luminaire part 2 that surrounds the mounting part 3 in the operating state, which is generally advantageous according to the invention. In the described embodiment, stops 210 are also provided on the luminaire part 2, against which the mounting part 3 can bear with corresponding stop sections in the operating state, thereby ensuring even further improved guidance of the mounting part 3 and the luminaire part 2 relative to each other.In the described embodiment, the luminaire part 2 is manufactured starting from a pre-basic body which is produced by means of metal die casting, wherein both the further light emission opening provided on the top, which is in . Figure 3a It is shown that the shape of the hooks of the first joint section 23 as well as the shape of the projection of the first fixing section 21 are produced by mechanical processing of the pre-base body, namely in this case by milling.

[0042] In Figure 4 comprehensive the Figures 4a, 4b and 4cThe mounting part 3 of an embodiment of a luminaire according to the invention is shown with a connection bracket 34 mounted thereon. A plug connector 36 and a terminal block 360 are fixed to the connection bracket 34. When mounting a luminaire 1 according to the invention, it is advantageously provided that an electrical supply cable is first guided through one of the feedthrough openings 37 from the mounting side of the mounting body 3 to its side facing away from the mounting side and then connected to the terminal block 360. The terminal block 360 is electrically connected to the plug connector 36.Thus, the luminaire part 2, with its luminaire components arranged therein and equipped with a plug-in device corresponding to the plug-in device 36, can be mounted particularly easily on the mounting part 3 by first plugging the corresponding plug-in device for supplying the luminaire components onto the plug-in device 36 and then fixing the luminaire part 2 to the mounting part 3 as described. From the overall view of the... Figures 3 and 4It is further evident that fixing cams 300 are provided on the bottom of the trough-like section of the mounting part 3, which in the assembled state points towards the component, around which the electrical supply cable can be wound within the trough-like section or within the trough formed by it, so that the supply cable is safely and without damage stowed on the side of the mounting part 3 facing the component, if it has an excess length, as is usual when mounting a light fixture.

[0043] In Figure 5 comprehensive the Figures 5a and 5bFigure 2 shows a luminaire part 2 of an embodiment of a luminaire according to the invention, as well as a luminaire component arrangement 10. The luminaire component arrangement 10 comprises a luminaire component holder 100 and luminaire components. Examples of luminaire components include optical elements 6, 7, light sources concealed by these, a control gear 11, and a radio module. The luminaire part 2 has a fixing device on a vertically extending inner surface that connects its upper surface to its lower surface. This fixing device is designed as a vertically extending linear guide. The fixing device has lateral guide rails 27 and a wedge-shaped central guide rail 26.The luminaire component assembly 10, with its luminaire component holder 100, can be placed on the inside of the luminaire part 2 and then inserted into it along the vertical direction, while the luminaire component holder 100 slides along the guide rails 26, 27. The luminaire component holder 100 is designed to correspond to the fixing device in such a way that the two together form a linear guide arrangement, as shown in particular in the figure. Figure 5bAs can be seen, the luminaire component holder 100 has guide sections 101, 102 corresponding to the wedge-shaped guide rail 26, which are designed to correspond to the guide rail in such a way that both centering perpendicular to the vertical direction Z and a fixed positioning along the vertical direction Z are ensured by the interaction of the luminaire component holder 100 and the fixing device, which is generally advantageous according to the invention. The positioning determined by the interaction of the luminaire component holder 100 and the fixing device, in Figure 5b After insertion in the vertical direction, the luminaire component holder 100 can be attached to the fixing device using the provided holding elements, in this case threaded holes, and screwed to it.

[0044] In Figure 6 comprehensive the Figures 6a and 6bThe interaction between the luminaire part 2, the optical element 6 and the cover 4 of an embodiment of a luminaire 1 according to the invention is shown, as is the case, for example, in Figure 1The cover 4 is shaped like a trough, which is generally advantageous according to the invention. The cover 4 has a thickness variation along the vertical direction Z, which in this case is formed by a step 410 formed by the side wall 41 of the trough-shaped cover, which completely surrounds the base 40 of the trough-shaped cover 4. The light emission opening of the luminaire part 2 is provided on the upper side of the luminaire part 2, which is bounded by a circumferential edge that forms a groove 24 designed to receive an end section 420 of the side wall 41 of the cover 4. The side wall 41 also forms a contact section 42 of the cover 4, which, in the operating state of the luminaire 1, rests against the circumferential edge of the first luminaire part 2.In the embodiment described here, the cover 4 is connected to the luminaire part 2 such that the side wall 41, with its end section 420, is bonded to the luminaire part 2 within the groove 24 of the circumferential edge. A diaphragm 60 partially closes the light emission opening, but the diaphragm 60 has an opening within which optical elements 6 and their respective associated LEDs are arranged. In this particular embodiment, and generally according to the invention, the diaphragm 60 is advantageously designed as a reflector plate. The optical elements 6 are designed for asymmetrical emission such that the light distribution they provide, with which they emit light that reaches them from the associated LEDs, is angled relative to the vertical direction Z.With this light distribution, in the operating state the light emitted by the LEDs reaches the cover 4, including the thickness variation of the cover 4, whereby the light is deflected further from the vertical direction Z by the thickness variation until it is emitted from an outside of the cover 4 into the vicinity of the luminaire 1.

[0045] In Figure 7 comprehensive the Figures 7a and 7b The interaction of the cover 8 with the luminaire part 2 of an embodiment of a luminaire is shown, as is the case, for example, in Figure 2 is shown. Such a cover 8 is located both on the top, which is in Figure 7a The cover is provided both on the top side, which is shown, and on the underside, which is not shown. The cover provided on the underside is illuminated by a light source arrangement comprising light sources and optical element 6, as is the case, for example, in Figure 6aAs shown, a further light source arrangement comprising another optical element 7 and further light sources concealed by it is provided on the upper side. This further light source arrangement is arranged at an angle to the vertical direction Z, whereas the further optical element 7 is designed to distribute the light emitted by the associated LED symmetrically upon it.
