SUMMARY OF THE INVENTION

Against this background, the present invention is based on the object of specifying a luminaire which can be configured in advance and then assembled for a wide variety of lighting effects or light scenes, which is also of compact design and yet in particular can achieve a large number of lighting effects that it despite its compact design makes it possible to dissipate the resulting amounts of heat in an effective way, and which can also be produced in an economical manner.

According to the invention, this object is achieved by a lamp with the features of claim 1 and / or by a housing component for a lamp with the features of claim 20 and / or by a method for producing a lamp with the features of claim 21.

A luminaire is proposed which has a housing component and at least one LED carrier board. The housing component has at least one portion protruding from a base of the housing component which is formed with a plurality of surfaces that are differently oriented relative to the base. The LED carrier board carries at least one LED device as a light source for providing light to be emitted by the lamp. In the luminaire according to the invention, the LED carrier board is arranged with a rear side thereof at least in sections on one of the multiple surfaces of the portion protruding from the base in such a way that the LED device overlays one of the surfaces at least in regions. Furthermore, in the luminaire according to the invention, the housing component in the area of the base thereof has at least one area which is designed as a cooling body for dissipating heat generated by the LED device during operation.

In addition, a housing component for a lamp, in particular for such a lamp, is proposed, the housing component having at least one dome-like section protruding from a base of the housing component, which is connected to the base in a freestanding manner and is formed with a plurality of surfaces that are differently oriented relative to the base . In the area of the base of the housing component, the housing component has at least one area which is designed as a heat sink. The housing component is also set up for fastening at least one LED carrier board, which carries at least one LED device as a light source for providing light to be emitted by the luminaire, on the housing component in such a way that the heat generated by the LED device during operation is transferred the section protruding from the base can be carried away into the area designed as a heat sink.

• Bereitstellen einer Gehäusekomponente mit einer vordefinierten Anzahl an Funktionsfeldern, wobei die Gehäusekomponente mehrere von einer Basis der Gehäusekomponente vorstehende Abschnitte aufweist, welche insbesondere gleichartig ausgebildet sind und jeweils mit mehreren relativ zu der Basis unterschiedlich ausgerichteten Flächen ausgebildet sind, wobei in jedem der Funktionsfelder einer der mehreren von der Basis vorstehenden Abschnitte angeordnet ist;
• Bestücken der Gehäusekomponente mit einer LED-Trägerplatine oder mehreren LED-Trägerplatinen und/oder mit einer Baugruppe oder mehreren Baugruppen, die jeweils mindestens eine LED-Trägerplatine und mindestens eine optische Komponente umfassen, derart, dass die LED-Trägerplatine oder mehrere der LED-Trägerplatinen jeweils mit einer Rückseite derselben mindestens abschnittsweise in der Weise auf einer der mehreren Flächen eines zugeordneten der von der Basis vorstehenden Abschnitte angeordnet wird oder werden, dass eine auf der LED-Trägerplatine vorgesehene LED-Einrichtung die eine der Flächen zumindest bereichsweise überlagert.

Furthermore, a method for producing a lamp, in particular such a lamp, is proposed, the method comprising the steps:

• Providing a housing component with a predefined number of functional fields, wherein the housing component comprises a plurality of a base of the housing component has protruding sections, which in particular are of identical design and are each designed with a plurality of surfaces that are differently oriented relative to the base, one of the plurality of sections protruding from the base being arranged in each of the functional fields;
• Equipping the housing component with an LED carrier board or several LED carrier boards and / or with an assembly or several assemblies, each comprising at least one LED carrier board and at least one optical component, in such a way that the LED carrier board or several of the LED carrier boards each with a rear side of the same is or are arranged at least in sections on one of the multiple surfaces of an associated one of the sections protruding from the base such that an LED device provided on the LED carrier board overlays one of the surfaces at least in some areas.

The idea on which the present invention is based is to propose a luminaire whose structure follows a modular system approach. The lamp according to the invention can be configured in a flexible manner even before its assembly, in other words before the individual parts of the lamp are assembled, and can thereby be individually designed and shaped. There is therefore a high degree of modularity and flexibility. The modular, configurable construction of the lamp is made possible by the housing component of the lamp provided according to the invention, the protruding portion of which is formed with the surfaces that are differently oriented relative to the base. In this way, it is possible, for example, to use the LED carrier board in such a way that light can optionally be emitted according to the radiation characteristics of a downlight or a wall washer, for example with the aid of optical components provided for this purpose. For a given size of the lamp, only a single shape of the housing component is required. One and the same type of housing component enables differently configured luminaires and thus a wide range of lighting effects. Depending on the desired effect to be achieved with the LED device and the desired main direction of radiation, for example in the manner of a downlight or wall washer, the back of the LED carrier board can be placed on one of the differently oriented surfaces of the section protruding from the base . With one and the same housing component, a wide variety of arrangements of the LED carrier board can be achieved with a compact and cost-saving design of the luminaire, combined with effective heat dissipation via the section protruding from the base and the area designed as a heat sink, and thus effective cooling of the LED device. The luminaire can be configured before it is produced and delivered, for example when ordering, for example by the customer or lighting designer. The multifunctional housing component combines a housing function and, with the area acting as a heat sink, a cooling function in one and the same component. This also contributes to a compact luminaire. In particular, the luminaire can be designed to be comparatively small to save space and yet illuminate a large area of space.

The at least regional superimposition of the LED device with the surface of the section protruding from the base is to be understood here in such a way that cases are also included in which one / more further components (n ) is / are present, in particular a portion of the LED carrier board on which the LED device is arranged. In this sense, the above-mentioned superimposition can be understood to mean that the LED device covers the mentioned surface of the section protruding from the base at least in some areas, although one or more further components, in particular the mentioned sub-area of the, between the LED device and the surface LED carrier board, can be arranged / can. Arrangements in which the LED device is located completely within the limits of the surface mentioned or the surface is completely overlaid by the LED device should in particular be included.

Advantageous refinements and developments emerge from the dependent claims and from the description with reference to the figures of the drawing.

In one embodiment, the housing component is cast in one piece, in particular die cast in one piece. Such a housing component can also be produced economically with a more complex shape.

In a preferred embodiment, the housing component is formed with a metal material. In particular, the housing component can be produced from a metal material, for example by die casting. The metal material can be aluminum or an aluminum alloy, for example. Such a housing component is well suited to act as a heat sink in some areas and is also robust.

In one embodiment, a base area of the housing component is designed in particular to be rectangular or square. This can be useful in many assembly situations. However, other shapes are also conceivable.

The section protruding from the base is preferably designed to be freely connected to the base. This allows easy access to the previous section.

According to the invention, the section protruding from the base of the housing component is designed like a dome. According to the invention, the outer shape of the section protruding from the base has the shape of a truncated pyramid. In this way, surfaces that are sufficiently large and suitably aligned, for example also inclined with respect to the base, can be created.

In one embodiment, the shape of the truncated pyramid is a shape of a truncated pyramid, in particular a straight pyramid with a square base, educated. However, other base surface shapes are also conceivable, in particular base surfaces in the form of a regular polygon. Such shapes have advantageous symmetries.

In particular, the outer shape of the section protruding from the base can have a rotational symmetry and can be mapped onto itself, for example, by rotating around an axis through a defined angle. For example, it can be provided that the outer shape of the section protruding from the base can be mapped onto itself when rotated about an axis by 90 degrees, which is the case, for example, with the above-mentioned shape of a truncated pyramid of a regular pyramid with a square base. This simplifies the arrangement of the LED carrier board in sections with its rear side optionally on different of the surfaces of the section protruding from the base.

In one embodiment, one of the surfaces of the section protruding from the base forms a top surface thereof and is preferably oriented essentially parallel to a main plane of extent of the base. Further of the surfaces of the section protruding from the base are designed in this embodiment as surfaces inclined to the main plane of extent of the base.

In particular, at least a portion of the rear side of the LED carrier board is arranged on the one of the plurality of surfaces of the portion protruding from the base in such a way that the LED device overlays the one of the surfaces at least in regions.

For example, for an LED device that provides light which is to be emitted by the luminaire in the manner of a downlight, the rear side of the LED carrier board can be arranged in sections on the top surface of the section protruding from the base. For an LED device, on the other hand, which provides light which is to be emitted by the luminaire in the manner of a wall washer, the rear side of the LED carrier board can be arranged in sections on one of the inclined surfaces of the section protruding from the base. The various inclined surfaces can in particular offer the possibility of choosing the direction of emission without the need for a modified housing component.

The surfaces of the protruding section which are oriented differently relative to the base can in particular be flat surfaces. This further facilitates the arrangement of the LED carrier board on one of these surfaces.

In one embodiment, the lamp has at least one adapter component which is provided with a recess in which the section protruding from the base can be received at least in some areas. Here, an LED carrier board is fastened to the adapter component in such a way that the LED carrier board fastened to the adapter component placed on the section protruding from the base is arranged with a rear side thereof at least in sections on one of the inclined surfaces of the section protruding from the base, that the LED device arranged on this LED carrier board overlies one of the inclined surfaces at least in some areas. With this configuration, a defined, stable arrangement of the LED carrier boards can be achieved in sections with their rear side on one of the inclined surfaces and reliable fastening of the LED carrier board in the housing component.

In a further development, the adapter component is cast in one piece, in particular die cast in one piece. Such an adapter component can be manufactured economically.

In particular, the adapter component is formed with a metal material. The adapter component, like the housing component, can be manufactured from a metal material, for example by die casting. The metal material can be aluminum or an aluminum alloy, for example. Such materials have favorable thermal conductivity properties for the adapter component and contribute to a robust adapter component.

In one embodiment, inclinations of opposing surfaces of the recess of the adapter component correspond to the inclinations of two of the inclined surfaces of the section protruding from the base. Furthermore, in a development, an inclination of a receiving surface of the adapter component for receiving the LED carrier board can correspond to the inclination of one of the further inclined surfaces of the section protruding from the base. In this way, in particular, stable fastening of the adapter component on the protruding section and good heat dissipation can be achieved through flat contact.

In a preferred embodiment, the housing component has a plurality of the sections protruding from the base, which are of identical design. Furthermore, the luminaire here has a plurality of functional fields, one of the plurality of sections protruding from the base being arranged in each of the functional fields. In particular, the section protruding from the base can in each case essentially be in the middle of the functional field be arranged. This enables a variety of different ways of arranging LED devices in such a way that effective heat dissipation is possible in a compact and expedient manner.

The plurality of sections protruding from the base and thus also the functional fields can be arranged along a line or in accordance with a two-dimensional pattern or grid. For example, the protruding sections and thus the functional fields can be arranged linearly in a row or instead in a matrix-like manner. This can further facilitate the arrangement of the LED devices and the LED carrier board (s) and expand the possible combinations. Such a lamp can also be designed in an aesthetically pleasing manner.

In one embodiment it can be provided that the lamp has only a single functional field. In preferred refinements, it can be provided that the lamp has several function fields, for example two, three, four, five or six function fields, or a different number of these, arranged in a row next to one another and thus "linearly". In further preferred embodiments, the function fields can be arranged in accordance with an n x m matrix with n rows and m columns, for example a 2 x 2 matrix or a 3 x 3 matrix or a 3 x 2 matrix. Here, n, m are each whole numbers.

In a preferred embodiment, the function fields can be square in shape. Other shapes, for example rectangular functional fields, are also conceivable. In particular, square functional fields can easily be arranged regularly and in a space-saving manner.

In one embodiment, the housing component in the area of the base has an area assigned to this function area for each function area, which area is designed as a heat sink for dissipating heat that can be generated by an LED device that can be arranged in this function area during its operation. The heat generated by each of the LED devices can thus be dissipated effectively and reliably, which can have a favorable effect on the service life of the LED devices, for example.

In one embodiment, the plurality of regions in the form of heat sinks are spaced apart from one another by channels on a rear side of the base that faces away from the sections protruding from the base. This improves the cooling effect of these areas continue. The channels can, for example, further improve the dissipation of heat through convection.

In one embodiment, the luminaire has a plurality of LED devices, each of which is assigned to one of the functional fields and is arranged in one of the functional fields. The luminaire thus has several light sources, which is advantageous for generating different light effects or illuminating different areas.

In one embodiment, the light has a plurality of LED carrier boards, each of the LED carrier boards carrying one or more of the LED devices. Carrier boards, each carrying an LED device, can be easily combined with one another and with other LED carrier boards. The assembly of the light can be simplified by arranging several LED devices on an LED carrier board. In one embodiment, all of the LED devices can be carried by the same LED carrier board.

In a further exemplary embodiment, several LED devices, each of which is assigned to one of several of the functional fields, are arranged on an LED carrier board. In this way, for example, LED devices aligned in the same way can easily be provided and built into the luminaire.

In a further embodiment, several LED carrier boards can be provided, each of which carries one of several LED devices, with each of the LED devices being assigned to one of the functional fields. In this way, the functional fields can be equipped with LED devices in different ways, for example with differently oriented LED devices.

In one embodiment, the plurality of LED carrier boards are designed differently from one another. In particular, the LED carrier boards can carry different numbers of LED devices, whereby, for example, one / more LED carrier board (s) each with a single LED device can be combined with one / more LED carrier board (s) each with several LED devices . The housing component makes it possible to combine different LED carrier boards in one luminaire in order to realize different functional fields and lighting effects. In particular, different board shapes can be combined in one luminaire, whereby, for example, a desired arrangement of LED devices for configuring the luminaire is possible in the simplest and most economical way possible.

In one embodiment, the luminaire has one optical component or several optical components. Here, the optical component (s) is / are each arranged in particular in one of the functional fields. For example, the optical component (s) is / are arranged in such a way that a functional field has a predefined radiation characteristic by means of the interaction of the optical component with the LED device, for example the radiation characteristic of a downlight or a wall washer. If several optical components are provided, then each of the optical components of the luminaire, in cooperation with the LED device assigned to the optical component, produces a respective predefined emission characteristic of the respective functional field. The radiation characteristics of different functional fields can differ from one another in order to generate different light effects and, for example, can each be designed as radiation characteristics of a downlight or wall washer. A combination of different radiation characteristics in one luminaire is thus possible in an economical way. With the help of the advantageous design of the housing component, each of the functional fields can be equipped in a selectable manner with the radiation characteristics of a downlight or a wall washer.

In particular, the back of the LED carrier board for a functional field with the radiation characteristics of a downlight can be arranged in sections on the top surface of the section protruding from the base. The rear side of the LED carrier board for a functional field with the radiation characteristics of a wall washer, on the other hand, can be arranged in sections on one of the inclined surfaces of the section protruding from the base.

The optical component can, for example, each have a rectangular or preferably square outer contour, in particular such that several of the optical components can be arranged next to one another, essentially filling a rectangular or square area.

In one embodiment, the optical component (s) is / are each designed as a reflector. However, it would also be conceivable to design the optical component (s) as lens (s). A combination of reflector (s) and lens (s) is also conceivable.

In one embodiment, in at least a first of the function fields, a first LED carrier board with a rear side thereof is arranged at least in sections on a first surface of the section protruding from the base, which is assigned to the first function field, that one of the first function field assigned to the first LED device carried by the LED carrier board is superimposed on the first surface at least in some areas. In this case, a first optical component is also arranged in the first functional field, which gives the first functional field a first emission characteristic. Furthermore, in this embodiment, in at least a second of the function fields, a second LED carrier board with a rear side of the same is arranged at least in sections on a second surface of the section protruding from the base, which is assigned to the second function field, that a second function field assigned, The LED device carried by the second LED carrier board is superimposed on the second surface at least in some areas. In this case, a second optical component is arranged in the second functional field, which gives the second functional field a second radiation characteristic. The first surface and the second surface are aligned in the same way relative to the base. In this embodiment, the first and second emission characteristics can be essentially the same or different from one another. Thus, two functional fields are provided which, by means of an optical component each, can emit light with a predefined emission characteristic, for example in the same main direction. In particular, in a further development, the first and second radiation characteristics can each be designed as a radiation characteristic of a downlight or as a radiation characteristic of a wall washer. The first and second functional fields can thus each emit in the manner of a downlight or in each case in the manner of a wall washer, for example.

In one embodiment, in at least a first of the function fields, a first LED carrier board with a rear side thereof is arranged at least in sections on a first surface of the section protruding from the base, which is assigned to the first function field, that one of the first function field assigned to the first LED carrier board carried LED device superimposed on the first surface at least in some areas. In this case, a first optical component is also arranged in the first functional field, which gives the first functional field a first radiation characteristic. Furthermore, in this embodiment, in at least a second of the function fields, a second LED carrier board with a rear side of the same is arranged at least in sections on a second surface of the section protruding from the base, which is assigned to the second function field, that a second function field assigned, The LED device carried by the second LED carrier board is superimposed on the second surface at least in some areas. In this case, a second optical component is arranged in the second functional field, which gives the second functional field a second radiation characteristic. The second surface is oriented differently relative to the base than the first surface. Here, in particular in a further development, the first and second emission characteristics each be designed as a radiation characteristic of a wall washer. In an alternative development, the first radiation characteristic can be designed as a radiation characteristic of a downlight and the second radiation characteristic can be designed as a radiation characteristic of a wall washer.

In one embodiment, a sensor device is arranged in at least one of the functional fields. Thus, the functional scope of the luminaire can be expanded to include an additional function in a space-saving and cost-saving manner.

In further refinements, the sensor device could be designed, for example, as a presence sensor or as a brightness sensor or as a humidity sensor or as a temperature sensor. However, sensor devices for detecting other parameters are also conceivable.

In one embodiment, the luminaire has a connection unit or a connection and control unit which is equipped with several connection devices by means of which the LED carrier board or several of the LED carrier boards can each be electrically coupled to the connection unit or the connection and control unit . In this embodiment, the housing component is trough-like with a bottom formed by the base, side walls, an inner area and an open side. The housing component has in a side wall a recess which also extends into the base for receiving the connection unit or the connection and control unit, the connection unit or the connection and control unit being flat and with its main plane of extent along the side wall in sections in the interior of the housing component and is received in the recess. Such a connection unit or connection and control unit can be accommodated in a space-saving manner and enables versatile, flexible coupling with the carrier boards.

In particular, the connection unit can be arranged essentially flush with an outside of the housing component. In this way, the connection unit is arranged in a particularly space-saving manner.

In one embodiment, the lamp has a central control arrangement which provides a plurality of channels for controlling the LED device or a plurality of the LED devices. In particular, several of the LED devices can be activated individually and / or combined in groups by means of the control arrangement. This enables highly flexible switching and / or control of the LED device (s). Provided a uniform lamp with multiple light sources that can be switched and / or controlled to generate different lighting effects can thus be achieved.

In one embodiment, each of the LED devices can be controlled separately by the central control unit via one or two control channel (s) assigned to the LED device.

In particular, the central control arrangement can provide at least one control channel or at least two control channels per LED device. With at least one control channel for each LED device, each of these can be controlled separately in terms of its light intensity. At least two control channels per LED device also enable the color of the emitted light to be changed, for example in the sense of "tunable white".

In further developments of the invention, several of the LED devices can be controlled via one or two common control channels.

In one embodiment, the lamp can be switched and / or controlled by means of a wireless or wired switching and / or control signal, in particular for switching and / or controlling the LED device (s) or groups of these. The luminaire can have an interface for receiving such a switching and / or control signal in a wireless or wired way. The lamp can preferably be switched and / or controlled wirelessly and has a corresponding interface.

In a further development, the central control unit can be set up to receive a switching and / or control signal for switching and / or controlling the LED device (s) or groups of the LED devices in a wireless and / or wired way, for example by means of a ZigBee interface or a DALI interface.

In one configuration, an electronic power component and / or an electronic power arrangement is or are arranged together with the LED device on the LED carrier board. Alternatively or additionally, the power electronic component and / or the power electronic arrangement can be provided on a further circuit board arranged at least partially within the functional field assigned to the LED device. The further circuit board can in particular be arranged at least in sections on one of the several differently oriented surfaces of the section protruding from the base, for example on one of the inclined surfaces. Power electronic Elements can thus be provided decoupled from the central control arrangement.

In one embodiment, the LED device (s) can be dimmed analogously. In the present case, analog dimming is to be understood in particular as a current dimming which, by regulating a constant current with which the LED device (s) is / are supplied for their operation, dimming of the light output by the LED device and thus in particular dimming of the light emitted by the aforementioned, assigned functional field. Such dimming differs from pulse dimming, in which dimming is achieved by periodically switching the light source on / off ("pulse").

The LED device (s) each has / have in particular at least one LED. The LED device (s) can be designed in particular as an LED (light-emitting diode or light-emitting diode) or as a group of several LEDs.

In one embodiment, the lamp is set up to supply the LED device or LED devices of the lamp with electrical energy by means of an external converter. This enables the provision of a luminaire that is simplified with regard to the control and supply of the LED device (s) while at the same time saving costs. With this configuration, power electronic components on the LED carrier board (s) or the further board (s) can be dispensed with.

In one embodiment, the lamp has an installation frame with which the housing component can be locked by means of spring-loaded elements, in particular spring-loaded balls, arranged on the housing component. For this purpose, the housing component can be inserted into the installation frame, the installation frame having an interior area corresponding to the housing component for receiving the housing component. By means of the spring-loaded balls, which in particular engage releasably in the installation frame, the housing component can be fastened and held in the installation frame reliably and in a simple manner. The housing component can simply be removed from the installation frame if necessary.

In a further embodiment, the installation frame is designed in such a way that the housing component can be introduced from two sides of the installation frame into its interior and can be locked to the installation frame. In this way, the frame can be used in two installation positions. For example, the installation frame can be set up in a first To be installed in such a way that a first edge of the mounting frame remains visible from a visible side after installation, and to be installed in a second layer in such a way that a second edge of the mounting frame is no longer visible from the visible side, for example by filling. This means that different installation situations can be met in a flexible manner.

In one embodiment of the method, the housing component is provided and equipped as a function of the configuration data provided by the customer when the lamp is ordered before it is manufactured. For the customer there is the advantage of being able to select a precisely fitting luminaire configuration from a large number of possible configurations that provides the desired effects. In the manufacture of the luminaire, a uniform housing component for every size of luminaire, i.e. for every number and geometric arrangement of functional fields, can be used to save costs. The housing component can be used in the same way for luminaires of various configurations without the need for post-processing.

In a further embodiment of the method, depending on the configuration data specified when the lamp was ordered, a program that can be executed by means of a data processing device of the control arrangement is uploaded to a storage medium of a control arrangement of the lamp. The luminaire is therefore also adapted to the selected configuration of the functional fields on the control side when it is delivered.

In one embodiment of the method, the fitting can include fitting the housing component with at least one LED carrier board and one optical component assigned to it one after the other.

It goes without saying that the above configurations and developments of the invention can be applied analogously both to the lamp according to the invention and to the housing component according to the invention and to the method of the invention.

The above configurations and developments can be combined with one another as desired, provided that it makes sense. Further possible configurations, developments and implementations of the invention also include combinations, not explicitly mentioned, of features of the invention described above or below with regard to the exemplary embodiments. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

DESCRIPTION OF EXEMPLARY EMBODIMENTS

A luminaire 1 according to an exemplary embodiment is illustrated in FIGS Figures 1 to 15 . The lamp 1 can for example be built into a suspended ceiling, for example, or attached to a ceiling, attachment to other parts of a building, for example in the wall area, being also possible. The luminaire 1 can be freely configured by the customer, for example by a lighting designer, before it is manufactured and delivered, for example in order to combine several light effects to be represented by the luminaire 1 in the desired manner in the luminaire 1.

The housing component 2 of the Figure 1 is die-cast in one piece from a metal material, for example aluminum or an aluminum alloy, the housing component 2 in the case of the in Figure 1 illustrated embodiment has a substantially square base. A height of the housing component 2 is significantly less than this edge length compared to the edge length of the square base area thereof, as a result of which the housing component 2 has the basic shape of a flat cuboid in terms of its external shape.

The housing component 2 has a base 3, the main extension plane 10 of which in FIG Figure 1 is indicated schematically. In the main extension plane 10, the housing component 2 has the aforementioned essentially square base area. The main extension plane 10 is one in Figure 1 plane spanned by the directions X and Y essentially parallel.

The housing component 2 is designed like a trough, the base 3 forming a bottom 19 of the housing component 2 and the housing component 2 further having side walls 20a to 20d which are connected to each other around the housing component 2 and delimit an inner area 21 of the same in the circumferential direction of the housing component 2 . In Figure 1 At the top, the housing component 2 has an open side 22.

From the base 3 stand in the inner area 21 in Figure 1 a plurality of projection-like sections 40 and 4 into it. The sections protruding from the base 3 4 are larger than the further sections 40. The function of sections 4 is explained in more detail below. The protrusion-like sections 40, which protrude into the inner region 21, are designed in different ways, but a large number of the sections 40 end in a direction Z normal to the main extension plane 10 at the same height relative to the base 3 and each with a fastening opening 41 are equipped, the function of which will also be explained later. In Figure 1 For the sake of clarity, only some of the sections 40 and the fastening openings 41 are provided with reference symbols. All sections 40, 4 are formed in one piece with the housing component 2. Many of the sections 40, and all of the protruding sections 4, are freestanding and integral with the base 3, see FIG Figure 1 .

Each of the sections 4 or "domes" protruding from base 3 is, see FIG Figure 1 , 7th , 9 and 10 , Dome-like, wherein in the example shown, the outer shape of the section 4 corresponds to the shape of a truncated pyramid of a straight pyramid with a square base. In this way, the section 4 each has a rotational or rotational symmetry about a central axis of the section 4 parallel to the direction Z, whereby the section 4 can be mapped onto itself by rotating 90 degrees about the central axis.

Each of the sections 4 protruding from the base 3 is designed in the same way as the other sections 4 and has, on an outer side thereof, a plurality of flat surfaces 5a to 5e that are differently oriented relative to the base 3. Here, the surface 5a forms a top surface of the section 4 that is essentially parallel and also essentially square to that through the directions X and Y, and thus to the main plane of extension 10, whereas the other surfaces 5b, 5c, 5d and 5e are inclined to the main plane of extension 10 are and together form a lateral surface of the truncated pyramid shape, see also Figures 9 and 10 . The section 4 is thus flattened on its upper side facing away from the base 3.

Each of the sections 4 protruding from the base 3 is assigned to a functional field 13 of the lamp 1 and is arranged centrally within the functional field 13. In the embodiment of Figures 1 to 15 the luminaire 1 has a total of nine function fields 13, which are shown in, for example Figure 5 clearly recognizable and indicated schematically by dotted lines. In this exemplary embodiment, the function fields 13 are arranged in the manner of a matrix corresponding to a 3 × 3 matrix, with all function fields 13 being the same size and each square.

Thus, in each of the functional fields 13 there are provided a surface 5a parallel to the main extension plane 10 and several surfaces 5b-5e inclined to the main extension plane 10 with the same inclination.

The base 3 of the housing component 2 has, for each functional field 13, an area 9 assigned to it, which is designed as a heat sink. See for example Figure 1 , 3 , 4th , 6th , and 8th . For the purpose of better heat dissipation, each area 9 is equipped with a plurality of cooling fins 45, which in particular are shown in FIG Figure 8 are visible. Furthermore, the areas 9, which are formed in one piece as partial areas of the housing component 2 with this, are arranged on a rear side 14 of the base 3, which faces away from the protruding sections 4, 40 and thus also from the inner area 21. The areas 9 are on the rear side 14 through channels 15, see in the example shown Figure 4 , form a grid pattern, spaced from each other. The channels 15 serve to further improve the cooling effect of the areas 9. In the channels 15 designed as air channels, an effective air flow can be achieved which, in combination with the large outer surface area of each heat sink area 9, contributes to effective heat dissipation. In the exemplary embodiment shown, in which, due to the plurality of LED devices 7, there may be a high need for effective heat dissipation, an optimized heat management is advantageously possible.

The housing component 2 is in an Figure 2 mounting frame 100 shown separately can be used. In the Figures 4 , 5 , 7th , 9 and 10 the housing component 2 is shown in a state inserted into the mounting frame 100.

The installation frame 100 is designed with an essentially square base area and has an inner region 101, the shape of which corresponds to the outer shape of the housing component 2 and which is provided for receiving the housing component 2. The housing component 2 can be inserted into the interior area 101 from a first open side 107 and, alternatively, from a second open side 108 of the installation frame 100. Inner side surfaces of the mounting frame 100 facing the inner region 101 are provided with edges 109 and 110 facing away from one another, the edges 109, 110 being provided on all four inner side surfaces of the mounting frame 100. On the outside of the housing component 2 in the region of the side walls 20b and 20d, spring-loaded balls 35 are arranged. The edges 109, 110 form circumferential steps which the spring-loaded balls 35 can grip from behind in order to hold the housing component 2 on the installation frame 100. Thus, the housing component 2 by means of the balls 35 can both Latch with the frame 100 when inserting from the first side 107 and when inserting from the second side 108.

The installation frame 100 can thus be used in two layers during installation, for example in a ceiling, either with a visible edge 105 facing towards a visible side or with an invisibly installable edge 106 towards the visible side. In the area of the edge 106, the installation frame 100 is equipped on its circumferential outer side with structures 104 which, for example, facilitate the “rimless” installation, for example by means of filling.

In this exemplary embodiment, the mounting frame 100 can be fastened in a ceiling (not shown in greater detail in the figures) with the aid of fastening devices 102 or 103 which are arranged on the outside of the mounting frame 100, see for example Figure 2 . The spring-like fastening devices 102 can be used for mounting the installation frame 100 in such a way that the edge 105 remains visible. In contrast, the fastening devices 103, which are designed as plate-like holding elements, are provided for the assembly of the installation frame 100 in the inverted position and thus with the non-visible edge 106 on the visible side. The fastening devices 103 can be inserted into the mounting frame 100 on the outside at different heights relative to the edge 106, in order to be able to take into account different thicknesses of a suspended ceiling.

It should be noted at this point that the in Figure 9 Section AA shown the alignment of the mounting frame 100, different from the section BB in Figure 10 , shows in an installation position in which the edge 106 points to the visible side of the built-in lamp 1. In this way, the possibility of installation in the two explained positions of the installation frame 100 is to be illustrated.

The lamp 1 makes it possible to switch between different light effects or light scenes in a variety of ways by switching or controlling accordingly. The luminaire 1 provides a flexible and compact lighting solution with which a wide variety of lighting effects can be achieved. For this purpose, in the case of the lamp 1, a plurality of optical components 16, which in the exemplary embodiment shown are reflectors in each case, are combined with one another within the housing component 2. In particular, the optical components 16 combined with one another in the housing component 2 are designed differently and generate different radiation characteristics.

With the luminaire 1 it is thus possible to arrange different optical components 16 in different positions within a uniform housing component 2 in the most varied of ways. In the exemplary embodiment shown, an optical component 16 with an outer shape that is square in plan view is arranged in each functional field 13. In the Figures 1 and 5 For a better illustration of the housing component 2, only two different optical components 16 - here reflectors - are shown, but with a lamp 1 in a finished state, preferably all function fields 13 are filled or equipped and none of the function fields 13 remains empty.

Light to be emitted by the luminaire 1 is provided by LED devices 7 which are designed as LEDs or groups of LEDs or which have these. The LED devices 7 are exemplified in Figures 9, 10 , 15th illustrated. Each of the LED devices 7 is arranged on an LED carrier board 6 which carries the LED device 7. The luminaire 1 thus has a plurality of LED devices 7, each of which is assigned to a function field 13 and is arranged in this function field 13. Several mutually different LED carrier boards 6 are combined with one another in the luminaire 1 according to the exemplary embodiment within the housing component 2 and fastened in the inner region 21. This will be explained in more detail below. Two different LED carrier boards 6 and associated optical components 16 are to be designated below by way of example with the reference symbols 6a and 6b or 16a and 16b.

Figure 1 shows an example of a first optical component 16a, which is designed as a reflector and is arranged in a first functional field 13a. The first functional field 13a here forms a first luminous field, which is given a first radiation characteristic by the reflector 16a which corresponds to the radiation characteristic of a downlight. In this example, the radiation characteristic of the first functional field 13a corresponds to a radiation characteristic of an individual luminaire that radiates along a main direction of radiation that is essentially perpendicular to the main extension plane 10, i.e. downwards in the case of ceiling mounting, and generates, for example, a circular or elliptical, more or less bundled light cone.

A first LED carrier board 6a is arranged in the functional field 13a, which is shown in FIG Figure 1 essentially horizontal, and thus parallel to the main extension plane 10 of the base 3, in which the inner region 21 of the housing component 2 is attached. The attachment of the LED carrier board 6a is on four by one in Figure 1 Sections 40 that are not visible because the protruding section 4 is covered by the LED carrier board 6a placed and screwed to the housing component 2 by means of screws and fastening openings 41 of these sections 40.

The optical component 16a is in Figure 1 arranged on the LED carrier board 6a, wherein the optical component 16a can in particular be plugged onto the LED carrier board 6a and latched to it. In other words, the LED carrier board 6a is located in the functional field 13a between the base 3 and the optical component 16a.

It is now on Figure 9 Referenced. The LED carrier board 6a carries the LED device 7 on its in Figure 9 upwardly facing front side, while the LED carrier board 6 with its rear side 8, which is oriented opposite to the front side carrying the LED device 7 and in Figure 9 pointing downwards, is seated in the area of the LED device 7 on the top surface 5a of the section 4. Depending on the size and positioning of the LED device 7, the rear side 8 of the LED carrier board 6a can be arranged completely or at least partially in the area in which the LED device 7 is located on the opposite front side on the top surface 5a. The rear side 8 of the LED carrier board 6a thus sits in sections on the top surface 5a in such a way that the LED device 7 at least partially covers the top surface 5a, and in the example of FIG Fig. 9 to a relatively large extent, superimposed. The essentially complete top surface 5a lies in the case of the in Fig. 9 Example shown on the back 8 of the LED carrier board 6a.

When the LED device 7 is in operation, it generates not only light but also heat, which in the case of the light 1 through the contact of the rear side 8 of the LED carrier board 6a with the top surface 5a effectively and efficiently via the dome-like section 4 in the as Heat sink formed, the section 4 associated area 9 is derived. In the area 9, the heat can then be dissipated further, in particular given off to the surrounding air by convection. Effective cooling of the LED device 7 is achieved even when the light 1 and the housing component 2 are low in the Z direction.

The LED carrier board 6 with the LED device 7 carried by it and the optical component 16a can form a first assembly 27a.

In the second function field 13b, see Figure 1 , a second optical component 16b is arranged, which is different from the optical component 16a. The second optical component 16b gives the second functional field 13b, which in this example forms a further luminous field, a second radiation characteristic, which is the radiation characteristic of one Wallwashers corresponds. In other words, when the luminaire 1 is mounted on the ceiling, a main radiation direction of the functional field 13b is not perpendicular to the main plane of extension 10, but rather inclined to it, such that a wall can be illuminated, for example.

It will be on Figure 10 referenced. A second LED carrier board 6b is arranged in the second functional field 13b, which in turn carries an LED device 7 on a front side. See also Figure 15 , in which the carrier board 6b and the LED device 7 can be seen enlarged. A rear side 8 of the LED carrier board 6b, which faces away from the front side carrying the LED device 7, sits in sections on one of the inclined surfaces 5b to 5e of the section 4 in Figure 10 for example on the surface 5b. The rear side 8 of the LED carrier board 6b is thus in FIG Figure 10 arranged in sections in the area of the LED device 7 assigned to the second functional field 13b on one of the lateral surface sections of the section 4. The back 8 thus sits in Fig. 10 in sections in such a way on one of the surfaces 5b to 5e, here 5b, that the LED device 7 overlays the surface 5b in regions. In Figure 10 the arrangement of the LED carrier board 6b is such that the LED device 7 carried by the LED carrier board 6b protrudes over an upper end of the section 4 and thus over the top surface 5a. A large part of the inclined surface 5b lies in Fig. 10 on the rear 8 of the LED carrier board 6b.

The LED carrier board 6b in Figure 10 is thus different from the LED carrier board 6a in FIG Figure 9 aligned. In Figure 10 the LED carrier board 6b is strongly inclined to the main extension plane 10 of the base 3, corresponding to the inclination of the surface 5b relative to the plane 10. The inclination of the surfaces 5b-5e relative to the plane 10 can be between 75 degrees and 85 degrees, for example, and is exemplary in the embodiment shown, 81 degrees.

The optical component 16b is, see for example Figure 15 , formed with a reflective section 16b ', which is arched and allows a lateral emission and guidance of light, inclined to the plane 10. In an in Figure 10 and 15th In the lower area, the LED device 7, which is also inclined in accordance with the inclination of the LED carrier board 6b, radiates light into the reflective section 16b '. The section 16b 'can be designed as an integral part of the optical component 16b, or the optical component 16b can be constructed in several parts, the section 16b' forming a part of the optical component 16b and being able to be joined together with an additional cover element.

The LED carrier board 6b and another board 6 'are fastened by means of screws 42 to an adapter component 11, which will now be described in more detail.

The adapter component 11, see in particular Figures 11 to 15 , has an outer shape in the manner of a lying prism, which is attached to an in Figure 11 upper long side through a step 11 'and on the opposite, in Figure 11 The lower long side is modified by a large recess 12. The recess 12 has a shape which is selected such that the size and inclination of inclined flat inner surfaces 12 ′ and 12 ″ correspond to the size and inclination of two opposite surfaces 5b-5e of the section 4.

The adapter component 11 has inclined first and second side surfaces 43 and 44 pointing away from one another, the inclination of which in turn corresponds to that of two opposite surfaces 5b to 5e of the protruding section 4 and to which the recess 12 is open. In other words, analogously to section 4, the outer shape of which corresponds to a regular truncated pyramid with a square base, all surfaces 12 ′, 12 ″, 43 and 44 of adapter component 11 are arranged with the same inclination with respect to main extension plane 10 of base 3. The section 4 protruding from the base 3 can thus be received in four angular positions, each offset by 90 degrees, around the central axis of the section 4 in the recess 12, such that the recess 12 is essentially completely filled and the received part of the Section 4 does not protrude beyond the surfaces 43 and 44.

The adapter component 11 is die-cast in one piece from a metal material, for example aluminum or an aluminum alloy, for example made of the same material as the housing component 2.

In order to arrange the LED carrier board 6b with its rear side 8 in the manner described above on one of the surfaces 5b to 5e, the LED carrier board 6b is arranged on the first side surface 43 and fastened by means of the screws 42, while the further board 6 'is on the second side surface 44 of the adapter component 11 is arranged and fastened by means of further screws 42, see Figure 12 . For fastening the boards 6b, 6 ', the adapter component 11 is provided with fastening openings 43', 44 'in the area of the side surfaces 43 and 44.

Furthermore, the optical component 16b can be plugged onto the adapter component 11 and, for example, fastened and held on the adapter component 11 by means of suitable fastening means, for example by latching or screwing.

An assembly 27b formed with the optical component 16b, the circuit boards 6 'and 6b and the adapter component 11, see Figures 12 and 13 , can then be placed on one of the protruding sections 4 of the housing component 2 in one of the four mentioned angular positions. In Figure 1 for example, the surfaces 12 'and 12 "sit on the inclined surfaces 5c and 5e, respectively.

In the bottom 19 of the housing component 2, see Figure 5 The base 3 is provided with further fastening openings 48 arranged around the protruding portion 4, one fastening opening 48 being arranged in front of each of the inclined surfaces 5b to 5e. The fastening openings 48 are thus regularly arranged at an angular distance of 90 degrees around the central axis of the section 4 parallel to the direction Z, within the respective functional field 13 and within an imaginary square defined for each functional field 13 by the associated fastening openings 41. The adapter component 11 can thus be fastened to the housing component 2 in each of the four angular positions by screwing from the rear side 14 of the base 3 using screws 49 and the fastening openings 48 and pulled against the section 4. In this way, the adapter component 11 also comes into good contact with the section 4. The adapter component 11 is provided with suitable, unspecified openings into which the screws 49 can be screwed through the openings 48.

The adapter component 11 thus makes it possible to use the above section 4, without reworking the housing component 2 being necessary, also to equip the functional field 13b in the manner of a wall washer. In the case of the functional field 13b, the rear side 8 of the LED carrier board 6b rests in areas on the inclined surface 5b of the section 4 and in areas on the first side surface 43 of the adapter component 11. In particular, see Figure 10 , the rear side 8 rests partially in the area of the LED device 7 arranged on the opposite front side on the surface 43, while a further part of the rear side 8 is seated in the area of the LED device 7 on the surface 5b, whereby the LED device 7 the Area 5b superimposed in areas. It should be mentioned that in variants the position of the LED device 7 can vary such that the rear side 8 is essentially completely seated in the region of the LED device 7 on the surface 5b. Alternatively, the rear side 8 in the area of the LED device 7 can sit to a large extent on the surface 43, in the latter case the rear side 8 of the LED carrier board 6b still in this way on the inclined surface 5b of the section 4 - or, depending on the orientation of the Adapter component 11 and thus the optical component 16b, one of the further inclined surfaces 5c, 5d or 5e - is arranged that another area Overlay of the LED device 7 with this inclined surface, here 5b, is given. In this way, via the section 4, the heat generated by the LED device 7 during operation can in turn be effectively dissipated into the region 9, from which it is further dissipated. The circuit board 6 'can also sit with its rear side on the surface 5d.

Looking at area 9, the show Figures 9 and 10 In addition, the walls of the dome-like section 4 are located on the rear side 14 of the base 3 in cooling fins 46 connected in the manner of a square, see FIG Figure 8 , continue. Another cooling rib 47 radiates out from the corner regions of the ribs 46 connected as a square.

Each functional field 13 and thus each LED device 7 is thus assigned an area 9 designed as a heat sink in order to effectively cool the LED device 7.

The ones in the Figures 1 , 5 Functional fields 13 that have not yet been equipped are also equipped to complete the lamp 1, in that further LED carrier boards 6 with LED devices 7 carried by them are fastened in the housing component 2. In this case, for each of the LED devices 7, the heat generated by the latter during operation is dissipated into the respectively assigned area 9. The further functional fields 13 can each be set up as luminous fields, for example in the manner of a downlight, such as in the case of the functional field 13a, or in the manner of a wall washer, such as in the functional field 13b. With the nine function fields 13 of the Fig. 1 , 5 This results in a large number of possible combinations within the housing component 2.

An individual LED carrier board 6 can be provided for each of the functional fields 13, each of the LED carrier boards 6 then carrying an LED device 7. However, LED devices 7 of adjacent functional fields 13, for which the LED devices 7 are to be arranged in the housing component 2 in the same way relative to the protruding section 4, can also be arranged on a common LED carrier board 6.

This is exemplified in Figure 16 illustrated. Figure 16 (a) shows an LED carrier board 6 which carries nine LED devices 7. The LED devices 7 are arranged in the housing component 2 on the LED carrier board 6 in accordance with a 3 x 3 arrangement of the protruding sections 4. The LED carrier board 6 of the Figure 16 (a) can as a whole in the housing component 2 of the Figure 1 arranged and fastened on a number of the sections 40. In this variant, the LED carrier board 6 is in Figure 16 (a) Not visible rear side 8 in the area of each of the LED devices 7 on the top surface 5a of the section 4 assigned to the LED device 7, in such a way that each of the LED devices 7 overlays the top surface 5a of the assigned section 4 at least in some areas. For example, all in Figure 16 (a) The LED devices 7 shown may be provided to provide light in the manner of a downlight in each of the functional fields 13 in interaction with corresponding, possibly different, optical components 16.

Figure 16 (b) shows a group of four LED devices 7 arranged in a 2 x 2 grid, which are carried by an LED carrier board 6 according to a further variant, while Figure 16 (c) an LED carrier board 6 with a single LED device 7 is illustrated.

More LED carrier boards 6 are in the Figures 16 (d) and 16 (e) shown, for example for a linear arrangement of three LED devices 7 arranged next to one another in a row or for two LED devices 7 arranged next to one another.

The ones in the Figures 16 (a) to 16 (e) The LED carrier boards 6 shown are set up to be arranged with their rear side 8 in sections on the top surface 5a. In other words, these LED carrier boards 6 are shown in FIG Fig. 1 placed on the sections 4 from above.

The Figure 16 also shows in the partial images (f) to (k) that with the side, ie on the inclined surfaces 5b to 5e on the rear side to be arranged in sections, for example to enable wallwasher light fields analogous to the function field 13b described above, also several LED devices 7 can be arranged on an LED carrier board 6. For example shows Figure 16 (f) the configuration of an LED carrier board 6 for three LED devices 7 to be arranged next to one another in a row, which point in the same direction in the finished luminaire 1, in other words, the LED carrier board 6 of FIG Figure 16 (f) can be arranged in the housing component 2 in such a way that this board 6 with its in Figure 16 The invisible rear side is seated in sections on an inclined surface 5b-5e of three sections 4 arranged next to one another in the housing component 2 in such a way that each of the LED devices 7 overlays the inclined surface of the associated section 4 at least in some areas. The board 6 of the Fig. 16 (f) can thus with their back 8, for example, sections of three arranged side by side on the surface 5b Sections 4 are seated, with an adapter component 11 then being placed on each of the three sections 4 arranged next to one another.

Out Figure 16 (g) and 16 (h) It can be seen that an LED carrier board 6 can also be provided for two LED devices 7 arranged next to one another, as well as for a single LED device 7 which are or is to be arranged inclined in the housing component 2.

Furthermore, the Figure 16 in partial images (i) to (k) further circuit boards 6 ', for three or two LED devices 7 arranged next to one another, and for a single LED device 7, analogous to the arrangement of FIG Figs. 12, 13 . For example, the board 6'der Fig. 16 (d) be attached to three adapter components 11 arranged next to one another.

Each of the LED devices 7 of the lamp 1 is assigned to one of the function fields 13 and is arranged in the respectively assigned function field 13. Within a luminaire 1, until the housing component 2 is completely equipped, LED carrier boards 6 of various types, as in FIG Figure 16 illustrated, combined with each other. A wide variety of lighting requirements can thus be taken into account in the configuration of the lamp 1. Some of the functional fields 13 can, for example, emit light in the manner of a downlight, while other functional fields 13 act as wallwashers. Post-processing of the housing component 2 is not necessary. Depending on the requirements, the number and / or the cut of the LED carrier boards 6 and possibly the number of adapter components 11 used can vary.

With a view to Figure 16 it should also be pointed out that the LED carrier boards 6 can have a cutout 80, the function of which will be explained below.

Although the housing component 2 can be completely filled in such a way that each function field 13 forms a light field, in one variant it can be provided that a sensor device 50 is arranged in one of the function fields 13 instead of an LED device 7. The sensor device 50 could be provided on a single circuit board provided specifically for this purpose, or instead of an LED device 7, it could be arranged on one of the LED carrier boards 6. The functional field 13 equipped with the sensor device 50 could also be provided with an optical component adapted to the sensor device 50 and / or with a suitable cover (not shown) adapted to the shape of the functional field 13 and the function of the sensor device 50. The sensor device 50 can be, for example, a presence sensor, be a brightness sensor, a humidity sensor or a temperature sensor or any other desired sensor.

The luminaire 1 is designed as a uniform luminaire which, in the exemplary embodiment shown, has a plurality of light sources which are formed by the LED devices 7 and to each of which an optical component 16 is assigned. The multiple light sources in the luminaire 1 can be switched and / or controlled flexibly in order to generate different lighting effects, for example individually or in different groups.

The lamp 1 has a connection and control unit 17, see FIG Figure 1 , 5 , 6th , 8th , wherein the connection and control unit 17 has a central control arrangement 25 and a plurality of connection devices 18. The central control arrangement 25 and the connecting devices 18 are arranged, for example, on a control board of the connection and control unit 17. The connecting devices 18 can be set up to produce plug connections. Each of the LED carrier boards 6 can be electrically coupled to the connection and control unit 17 by means of the connection devices 18.

A recess 23 is made in the side wall 20c of the housing component 2 and is open to the outside of the housing component 2 and also extends into the base 3. The recess 23 is provided to accommodate the flat connection and control unit 17. The connection and control unit 17 is received in the recess 23 in such a way that a main extension plane 24 of the connection and control unit 17, see FIG Fig. 4 and 5 , along the side wall 20c. The connection and control unit 17 is thus arranged essentially parallel to the side wall 20c and essentially in a center of the side wall 20c. The connection and control unit 17 is inserted into the recess 23 from the rear side 14 and protrudes a little into the inner region 21. The cutouts 80 of the LED carrier boards 6 create space for the connection and control unit 17. The connection and control unit 17, which, for example, has a housing which carries the control board, does not protrude beyond the side wall 20c on an outside of the housing component 2, but is flush with this.

The central control arrangement 25 can have a DALI module for a wired reception of a switching and / or control signal or a ZigBee module for a wireless reception of a switching and / or control signal. Electric power for operating the lamp 1 is provided via a connection line 90 coupled to the connection and control unit 17. The connection line 90 can also, if switching and / or control signals are received by the control arrangement 25 in a wired manner, provide these switching and / or control signals via corresponding conductors of the connecting line 90.

The in Fig. 1 The example shown, nine slots are available, which form nine connecting devices 18. This enables up to nine plug connections. So up to nine connections each with an LED carrier board 6 - one of which could, for example, be a carrier board for the sensor device 50 - can be established, in other words, each functional field can have its own LED carrier board 6, which is specially and separately is connected to the control arrangement 25 by means of the connecting devices 18. The connection of the LED carrier boards 6 or LED devices 7 to the connection devices 18 takes place within the inner area 21 by means of flexible cables. In the case of assembly 27b of the Figs. 12, 13 Alternatively, the connection between the LED carrier board 6b and the connecting device 18 could also be established via the board 6 ', which in turn is coupled to the board 6b.

In a variant of the lamp 1 with great flexibility in the control of individual function fields 13, the central control arrangement 25 enables a large number of control channels, for example 18 channels. In this variant, the connecting devices 18 are each designed, for example, as four-pole plug connections, nine plug connections being provided. In this way, two control channels can be provided for each functional field, one of these for dimming the respective LED device 7, i. the control of the light intensity, and the second can be used to control the color temperature of the light emitted by the LED device 7 ("tunable white"). A luminaire 1 configured in this way can be configured and controlled in a highly flexible manner. The central control arrangement 25 provides two control channels for each LED device 7. The control channels are controlled flexibly and individually with the aid of the central control arrangement 25.

Alternatively, the central control arrangement 25 can be designed to provide 9 channels if only the light intensity of the individual LED devices 7 is to be controlled. In this case, too, nine plug connections are provided.

In the embodiment of the lamp 1, power electronic components 29 are arranged as a power electronic arrangement 28 together with the LED device 7 or the LED devices 7 on the LED carrier board 6 and thus "brought" up to the LED devices 7. Alternatively, at least some of the power electronics Components 29 can be arranged on a further circuit board 6 ′ in the functional field 13. This is exemplified by the Figures 12 and 13 for the carrier board 6b and the further board 6 ', the board 6' also being attached to the adapter component 11 in the functional field 13b of the LED carrier board 6b adjacent.

The LED carrier board 6 is coupled to the central control arrangement 25 by means of the four-pole plug connections, which serve as connecting devices 18, and for example by means of flexible cables, the four contacts of the plug connections then having two contacts for the two control channels and one contact for the supply voltage as well as a contact for the earth. 48 volts, for example, are provided as the input supply voltage. In the case of a sensor device 50, the control channels can serve as return channels for the sensor device 50.

The voltage supply brought in via the connecting line 90 is thus connected to a single splitter, which distributes the electrical power further and provides a control signal for each control channel.

As described above, the number and design of the LED carrier boards 6 can vary depending on the desired configuration of the luminaire 1. Likewise, a different number of the channels provided can be used in a luminaire 1.

The central control arrangement 25 has a data processing device 62, e.g. B. a processor and a storage medium 61. This is purely schematic in Figure 7 indicated by way of example.

The LED devices 7 can be dimmed analogously in the lamp 1 according to the exemplary embodiment described above. Analog dimming with linear controllers is provided for this. Alternatively, switching regulators could be provided.

The assignment of a different number of LED carrier boards 6 at different positions within the housing component 2 to a different number of control channels will be explained in more detail below.

There are different ways of controlling the LED devices 7. It is not only possible to assign a control channel to each LED carrier board 6, but also several LED devices 7, regardless of whether they are arranged on a common LED carrier board 6 or on several, to form one joint controllable group. Furthermore, it is basically also conceivable to address two or more LED devices 7 arranged on a common carrier board 6 via different control channels, provided the LED carrier board is set up for this.

The Figures 17 and 18th illustrate some possibilities for the configuration of the luminaire 1 according to the exemplary embodiment described above.

Figure 17 (a) shows a configuration of the luminaire 1 in which four functional fields 13, each designed with a wallwasher function, are provided at the corners of the 3 × 3 grid. Two of the wallwasher fields form a controllable group 201, while two more of the wallwasher fields form a further group 203 that can be controlled separately from group 201. In the middle of the sides of the 3 x 3 grid, downlight function fields 13 with an elliptical light distribution are arranged, which can be controlled together as group 202. In the middle of the 3 x 3 grid there is an individually controllable function field 301 which has the function of a downlight with bundled light distribution. In the case of the Figure 17 (a) Thus, for example, nine individual LED carrier boards 6 are assigned to four control channels, it being assumed that only the light intensity for the individual LED devices 7 is controlled or switched.

In Figure 17 (b) there are three downlight function fields arranged in a row, each with elliptical light distribution, which are combined to form a group 206 that can be controlled together. A middle row is formed by three downlight function fields combined in a group 205 with a beam angle of 25 degrees, while in the in Figure 17 (b) In the top row, an individually controllable downlight field 302 is arranged between two wallwasher fields combined to form a group 204. In the case of the Figure 17 (b) five individual LED carrier boards 6 are thus assigned, for example, to four control channels.

Figure 17 (c) shows an analog configuration Figure 17 (b) where the fields of the in Figure 17 (b) groups 205 and 206 shown can now be controlled together as group 207. Here all LED devices 7 of group 207 are arranged on a common LED carrier board 6, as in FIG Figure 17 (c) indicated. Thus, in the configuration of the Figure 17 (c) an assignment of four individual LED carrier boards 6 to three control channels is provided.

In Figure 17 (d) a configuration is shown in which four LED carrier boards 6 are assigned to four control channels. In the in Figure 17 (d) An individually controllable function field 303 acting as a downlight is provided on the upper left corner of the 3 x 3 arrangement, whereas, starting from the lower right corner of the 3 x 3 arrangement, a group 210 of 2 x 2 jointly controllable downlight fields with a 25 degree beam angle are provided. The remaining functional fields 13 form wallwasher fields, which in Figure 17 (d) can shine upwards and to the left. In the Figure 17 (d) Wallwasher fields radiating upwards are combined in a group 208, while the wallwasher fields radiating to the left are combined in a further group 209. Again, the LED devices 7 combined in groups 208, 209 and 210 are each arranged on a common carrier board 6.

The arrangement of the Figure 17 (e) corresponds to the arrangement of FIG Figure 17 (d) , but now the in Figure 17 (d) Function fields 13 combined in two separate groups 208 and 209 are combined in a common group 211. The LED devices 7 of group 211 are nevertheless arranged on two LED carrier boards 6, one for the wallwashers radiating upwards and one for the wallwashers radiating to the left to the side. Four LED carrier boards 6 are thus assigned to three control channels.

In the configuration of the Figure 17 (f) two downlight fields are combined into a jointly controllable group 212, while the LED devices 7 of the remaining function fields 304 to 310 can each be controlled individually via an assigned channel. In this case, eight control channels are used. All function fields are designed as downlight fields, with the function fields of group 212 each generating an elliptical light distribution, fields 304 and 305 a beam angle of 25 degrees, fields 306 and 307 a beam angle of 35 degrees, and fields 308 and 309 a beam angle of 45 degrees, and the field 310 produce a highly focused light distribution.

In the Figure 18 The configuration shown corresponds to that of Figure 17 (f) , but the in Figure 17 (f) centrally arranged function field 310 is used differently. In the middle of the 3 x 3 grid is in Figure 18 a circuit board (not shown in detail) with a sensor device 50 is arranged.

However, the lamp 1 not only allows in the Figures 17 and 18th configurations shown, but offers many more configuration options.

In a method for producing the lamp 1 in accordance with the exemplary embodiment described above, the procedure is as follows:
A customer, for example a lighting designer, configures the luminaire 1, for example with software specially provided for this purpose, which the customer can download, for example, via a data network, such as the Internet, or operate directly via the data network.

For example, the customer first selects the size of the desired luminaire, for example a luminaire size that has a 3 x 3 grid as in Fig. 1 enables. Other sizes of the lamp can also be made available for selection, for example several function fields in a row, or a grid of function fields in the manner of a 2 x 2 or 3 x 2 grid.

The customer then configures the functional fields 13, in other words, he selects which light effect or which light distribution the functional field 13 is to produce. If a sensor is to be built in, the customer also chooses this.

The customer then has to specify the desired control options, for example to what extent the functional fields should be controllable separately or together in groups, and whether only the intensity or the color of the light should be controllable.

Depending on the aforementioned configuration data given by the customer in the course of configuring the lamp, a housing component 2 is provided, as explained above, and the suitable number and type of LED carrier boards 6 is determined, for example also with the aid of the software. Depending on the configuration data, these can then be built into the housing component 2 with the appropriate optical components 16 and, if necessary, adapter components 11. The necessary connections to the central control arrangement 25 are established by means of flexible cables.

In addition, the software can be used to provide, generate or configure a program executable by means of the data processing device 62 of the control arrangement 25, again depending on the configuration data provided by the customer, the program then being uploaded to the storage medium 61 of the control arrangement 25. The control of the function fields 13 can be effected or modified by means of the program. For example, the same control arrangement 25 can be used for differently configured lights 1, the functions of which are suitably adapted by uploading the program.

In the exemplary embodiment, the LED devices 7 can be connected in parallel in order to be able to control them separately. The aforementioned program (firmware) can define a maximum control current for each group channel that addresses a control group in order to ensure that all light sources can supply the same light intensity in the desired manner.

In a variant of the exemplary embodiment described above, the control of the LED devices 17 of the functional fields 13 of the luminaire 1 can be implemented in a simplified manner. While the embodiment described above is highly flexible and very versatile in the possible lighting effects, the luminaire 1 can be constructed without the central control arrangement 25 in a simplified embodiment, for example if simpler lighting effects and lower costs are desired. While the mechanical, optical and thermal concept explained for the exemplary embodiment described above remains unchanged, in the simplified variant the supply of the LED devices 7 takes place via an external converter 30 which can be arranged in the connecting line 90, for example. See the schematic in Fig. 19 . The converter 30 can be a DALI converter with one or two output channels, whereby a more cost-effective control with reduced complexity is provided for simpler applications.

In the case of such a simplified variant, all of the functional fields 13 could be designed, for example, as downlights or wallwashers, but a combined arrangement of downlights and wallwashers is also possible in the simplified variant described above with control via the external converter 30.

In the simplified variant with the external converter 30, the power electronic components 29 or arrangements 28 on the LED carrier boards 6 are also omitted. In this case, the electrical current for supplying the LED devices 7 is supplied directly from the external converter 30, in which case the connection and control unit 17 of the embodiment described above in the simplified variant now forms a connection unit 17 which z. B. only has a strain relief for the connection line 90 and plug connections for connecting the LED carrier boards 6 via flexible cables.

In further variants, starting from the exemplary embodiment described above with a central control arrangement 25, a reduced number of channels could be provided, for example for simpler applications in which several individually controllable light effects are to be combined in the luminaire 1. In such a case, the number of control channels could be less than nine, for example four or eight.

By means of the flexible control, the luminaire 1 thus makes it possible to display different lighting effects and different light scenes as well as to illuminate a large area of space while at the same time making the luminaire 1 very compact. This is achieved without a mechanical adjustment of individual light sources being provided. A flexible and modular coupling of different numbers of LED carrier boards 6 is possible. Furthermore, it becomes possible to arrange different optical components 16, for example different reflectors, at different positions in a uniform, single housing component 2 in a selectable combination without the housing component 2 having to be modified subsequently. For each size of the lamp 1, ie for a given number and geometric arrangement of functional fields 13, only one housing component 2 of a single type has to be manufactured, which advantageously reduces the costs for die casting tools and the variety of components. The housing component 2 is also optimized with regard to the dissipation of heat and enables efficient cooling of the LED devices 7. The luminaire 1 has a low height and thus also a comparatively small space requirement. The voltage supply and the control of the LED devices 7 succeed in a space-saving manner.

Although the invention has been fully described above on the basis of preferred exemplary embodiments, it is not restricted thereto, but rather can be modified in many different ways.
