Description

FIELD OF THE INVENTION

The invention relates to a luminaire, which can be used for example for the illumination of premises, of interiors or parts of buildings or architectural features or objects located in premises or persons application.

TECHNICAL BACKGROUND

Although the invention may be useful in many fields in which the illumination of objects or features is desirable or required, the invention and the underlying problem will be explained below using the example of the illumination of an interior in a building.

It is generally known to install lights for illuminating an interior, for example in a ceiling area. If, for example, a corridor is illuminated with the aid of individual ceiling spotlights, however, a relatively large number of these spotlights are required in order to illuminate them in the desired manner with the elongate shape of the corridor. In addition, the light emitted by the individual conventional radiators often falls on areas of the interior that are not to be illuminated, while other areas are in turn less well illuminated than desired.

In addition, it may happen that such a conventional lighting solution is not sufficient in all situations in which lighting is desired, the aesthetic requirements placed on the illumination fully.

Furthermore, it is generally known that reflectors of light sources such as headlamps can be equipped with free-form surfaces.

SUMMARY OF THE INVENTION

Against this background, the invention is based on the object to provide a luminaire, which avoids the above-mentioned disadvantages of conventional lighting devices and offers improved lighting options to illuminate the areas or objects to be illuminated targeted and efficient and the aesthetic requirements of the achieved lighting effect in many situations to be flexible.

According to the invention this object is achieved by a luminaire having the features of patent claim 1.

Accordingly, a luminaire is proposed that has a luminaire base body and luminous segments which can be inserted into the luminaire base body. In this case, it is provided that each of the luminous segments emits light in a directed manner and has a predefined emission characteristic. In this case, the emission characteristics of the luminous segments comprise at least two different emission characteristics.

One finding underlying the present invention is that the light emitted by the light segments can be used more efficiently in this way than when conventional radiators are used. In particular, it is possible to specifically illuminate desired areas, to avoid direct illumination of areas that are not to be illuminated, and to achieve different aesthetic lighting effects in a flexible manner in order, for example, to stage a room and / or an object and / or a person in various ways , Furthermore, by the more efficient, more effective light emission lamps can be saved, also the more efficient use of the emitted light can also offer the advantageous possibility of energy conservation. In particular, therefore, a luminaire can be created according to a modular principle. In other words, in particular a flexibly deployable luminaire system according to modular design is provided, which comprises the luminaire base body and the luminous segments.

In the present case, a radiation characteristic is understood to mean the directional light output (quantity) emitted by a luminous segment. The term of the emission characteristic should also be understood in particular to the effect that a sole rotation or pivoting as well as otherwise repositioning of a luminous segment does not change its emission characteristic.

Advantageous embodiments and further developments will become apparent from the dependent claims and from the description with reference to the figures of the drawing.

In one embodiment, at least two lighting segments can be inserted into the lamp base body. The luminaire base body is in this case designed for insertion of at least two light segments in these. In particular, in this case by the user when using the lamp, the total number of at least two or more light segments that can be inserted into the lamp base body are inserted for some applications in this, whereas for other applications by the user fewer light segments can be inserted into the lamp base body as the design of the lamp base body makes possible. A very flexible use of the lamp is made possible by this modular design. For example, a subsequent adaptation of the lamp during redesigns can be done easily in a business premises.

In one embodiment, the lighting segments can be inserted at predefined, for example regularly arranged, positions in the lamp base body. This allows a high flexibility in the assembly of the lamp base body, for example, with a selection of a total of available light segments. In particular, luminous segments, which are essentially the same in terms of their external shape, can thus be flexibly combined.

The lighting segments can be inserted in a development, for example, at positions that are specified by a regular grid, such as with each other perpendicular intersecting grid lines.

In one embodiment, the lighting segments can be inserted into the lamp base body in such a way that the inserted lighting segments form an arrangement extending in a plane, in particular a horizontal or vertical plane in an assembled state of the lamp. In this way, a variety of lighting effects can be achieved by means of the radiation characteristics of the lighting segments without complicated turning and pivoting mechanisms for the individual lighting segments. For example, if the plane in the mounted state of the luminaire extends substantially horizontally, optionally floor areas, wall areas or both can be illuminated, but the luminous segments need not be adjusted by pivoting or twisting, but can preferably be arranged fixedly aligned and from the horizontal out light. In an analogous manner, light effects can optionally be generated in floor, wall and / or ceiling areas when the plane is substantially vertical, in which case the preferably fixedly aligned lighting segments are illuminated from the vertical. In particular, by arranging the luminous segments in accordance with this embodiment by means of the luminaire, lighting effects can be achieved, for example, both in horizontal and in vertical subareas of a room. The generation of such light effects with an arrangement of luminous segments extending substantially in one plane can achieve an interesting aesthetic effect and, moreover, be advantageous, for example, when the luminaire is used in a grid ceiling.

For example, the arrangement may be formed in such a way that the luminous segments in the horizontal or vertical plane, for example, are inserted next to one another in a row or in two directions like a matrix in the luminaire base body.

In one embodiment, in the mounted state of the luminaire, the plane in which the arrangement extends may extend substantially parallel to a ceiling or substantially parallel to a wall of a room.

In a further embodiment, two or more of the inserted lighting segments may have the same emission characteristic. This can, for example, enable to provide several similar lighting effects or a larger lighting effect of a kind.

In one embodiment, the luminous segments each have an optical component, the use of which in each case achieves the emission characteristic of the luminous segment. In this case, in a further development, the luminaire can be equipped in particular with luminous segments in such a way that the luminaire has such optical components of at least two types of different design. Thus, the provision of different emission characteristics is achieved in a suitable manner.

In one embodiment, at least one of the light-emitting segments has a reflector as an optical component, or several or all of the light-emitting segments each have a reflector as an optical component, the reflector preferably having at least one light-reflecting partial surface formed as a free-form surface. In a development of this embodiment, at least one of a plurality of light-reflecting partial surfaces of the reflector is preferably designed as a standard reflector surface or as part of a standard reflector surface and at least one as a free-form surface. In this way, the emission of the luminous segment can be effectively influenced, in which case the reflector can be advantageously carried out with comparatively small dimensions.

A standard reflector surface may, for example, be a reflector surface of parabolic shape, in particular a reflector surface of parabolic shape with a facet structure. The standard reflector surface could thus be, for example, a paraboloid surface or a part thereof, possibly with a facet structure.

On the other hand, a free-form surface can be designed to be free in terms of geometry in order to specifically influence the reflection process on the light-reflecting partial surface designed as a free-form surface and to modify or optimize the light distribution achieved and thus the emission characteristic.

Thus, in this case, in one embodiment, the luminaire may in particular be equipped with luminous segments in such a way that the luminaire has reflectors of at least two differently designed types. This advantageously allows different emission characteristics and different light effects. In another embodiment, however, several of the reflectors may be of the same type.

In one embodiment, at least two of the light-reflecting partial surfaces are each designed as a standard reflector surface or as part of a standard reflector surface and at least two of the light-reflecting partial surfaces each as a free-form surface.

According to a further development, the reflector has two light-reflecting partial surfaces which are each formed as a standard reflector surface or as part of a standard reflector surface and which are arranged opposite one another. Furthermore, in this case, the reflector has two designed as free-form surfaces light-reflecting partial surfaces, which are arranged opposite to each other. This may be useful, for example, to produce a rather elongated cone of light to illuminate elongate areas such as aisles.

In one embodiment, the reflector is formed with four light-reflecting sides. Such a reflector can harmoniously form part of a four-sided luminous segment.

In one embodiment, adjacent ones of the light-reflecting partial surfaces are connected to one another at one of a plurality of corners of the reflector. A shape of the reflector with multiple corners can in turn contribute to setting the desired radiation characteristics.

In one embodiment, at least one of the free-form surfaces is formed to bulge toward a reflector inner area in the manner of a bulb. This too can be advantageous for generating a light distribution which is to be adapted to a region, for example, rather elongate to be illuminated.

In one embodiment, the reflector is designed as an injection molded part. In this case, for example, the reflector can also have a reflective layer connected to the injection-molded component. Such a reflector can be manufactured comparatively inexpensively, even if the reflector has a complex shape.

In other embodiments of the invention, the reflector can be manufactured by means of another manufacturing method. For example, the reflector can be made by forming a metal sheet, for example by means of one or more of the following methods: roll forming or cold rolling, bending, stretch drawing, drawing methods such as in particular deep drawing, pressing, embossing, stamping, deformation - for example deep drawing - by means of a rubber pad, Pressing, superplastic forming, hammering or drifting, explosion forms, magnetic pulse shaping.

In particular, it is provided according to a development that the shape of the reflector can not be changed by a user, but is fixed. Preferably, however, in embodiments of the invention, a series of light segments, each with a different reflector shape for different applications and / or effects provided, the reflector shape thus by an appropriate choice of the light segments already at the initial compilation of the configuration of the lamp or by later replacement of the light segments at Need can be varied. It thus eliminates complicated and expensive setting operations. Instead, the luminaire can advantageously be suitably configured by a customer, for example, when ordering for the desired intended use, for example by suitable combination of luminous segments with different emission characteristics.

In particular, in embodiments of the invention, a plurality of lighting segments can be combined in a luminaire, which have different reflectors each formed with at least one light-reflecting partial surface designed as a freeform surface.

In one embodiment, a plurality of reflectors with the same outer contour are advantageously provided, but each of the lighting segments a different Impart radiation characteristics. It can thus be offered lighting segments with different emission characteristics that can be selected by a customer as needed and inserted into the lamp base body. Due to the same outer contour of the reflector, such luminous segments fit well together, both with regard to the space requirement in the luminaire base body and with regard to the aesthetic effect. In further embodiments, for example, the reflectors of all lighting segments may have a substantially same outer contour. This can be particularly practical and practical under aesthetic aspects as well as when inserting the light segments. Alternatively, the light segments of the light can form groups within which the outer contour of the reflectors is the same.

The outer contour of the reflector may be in embodiments, for example, quadrangular, in particular square, or round, in particular circular. Also combinations of reflectors with square and round outer contours are conceivable.

In one embodiment, at least one of the luminous segments has a lens as an optical component, or several or all of the luminous segments each have a lens as an optical component. By means of a lens, it is likewise possible to achieve an effective influencing of the emission characteristic of the luminous segment.

In this case, in a further embodiment, the luminaire can be equipped in particular with luminous segments in such a way that the luminaire has lenses of at least two differently designed types. This in turn advantageously allows different emission characteristics and different light effects. In another embodiment, however, several of the lenses may be of the same type.

According to a further development, it can be provided, in particular, that the shape of the lens can not be changed by a user, but is fixed. In embodiments of the invention, a number of luminous segments, each with a differently acting lens, for example a different lens shape, are preferably provided for different applications and / or effects. Here, the lens type Thus, by an appropriate choice of the light segments already at the initial composition of the configuration of the lamp or by later replacement of the light segments can be varied if necessary. It thus eliminates complicated and complex setting operations, and the lamp can instead advantageously be suitably configured by a customer, for example, when ordering for the desired purpose, such as by matching compilation of light segments with different emission characteristics.

In particular, in embodiments of the invention, a plurality of light segments can be combined in one light, which have differently shaped lenses.

In one embodiment, a plurality of lenses with the same outer contour are advantageously provided, which in each case impart a different emission characteristic to the luminous segments. Thus, also in the embodiment of the optical component as a lens light segments can be offered with a variety of emission characteristics that can be selected by a customer as needed and inserted into the lamp base body. Due to the same outer contour of the lens, such luminous segments fit well together, both with regard to the space requirement in the luminaire base body and with regard to the aesthetic effect. In further embodiments, for example, the lenses of all light segments may have a substantially same outer contour. This can be particularly practical and convenient from an aesthetic point of view as well as when inserting the light segments. Alternatively, the luminous segments of the luminaire may form groups within which the outer contour of the lenses is equal.

In embodiments, the outer contour of the lens can, for example, be quadrangular, in particular square, or round, in particular circular. Also combinations of lenses with square and round outer contours are conceivable.

In one development, the lens may be a lens, the effect of which is based to a large extent on total internal reflection (so-called TIR lens in English, where TIR stands for "totally internal reflection").

In a further embodiment of the invention, at least one of the luminous segments may have a lens as an optical component, while at least one further of the luminous segments has a reflector as an optical component. In particular, the reflector here has at least one light-reflecting partial surface formed as a free-form surface. According to this embodiment, at least one luminous segment with a lens is thus combined with at least one luminous segment with a reflector. This can have an even more advantageous effect on the variety of producible light effects.

In one embodiment, the lighting segments are designed as exchangeable lighting segments. Thus, one or more light segments can advantageously be exchanged in order to replace the light segment (s) with one or more light segments having a different radiation characteristic and to vary the achievable light effects. In addition, a possibly damaged light segment can be easily replaced in this way.

For example, the lighting segments can be designed as exchangeable spots. The exchangeability not only allows the replacement of a luminous segment in case of damage, but also a certain variability of the luminaire in case of changes in an environment to be illuminated by means of the spots. Thus, for example, lighting effects can be easily varied, e.g. The lighting function of the luminaire can be influenced in many ways by changing light segments.

For example, in one embodiment, the luminaire base body can be rectangular, in particular square. A rectangular or square lamp base body may be useful, for example, when the luminaire is to be installed in a grid of a false ceiling.

In one embodiment, for example, four to nine lighting segments or four to sixteen lighting segments can be inserted into the lamp base body. In this case, in particular, for example, a rectangular grid with 2 x 2 insertion positions for light segments or with 3 x 3 such insertion positions or with 4 x 4 such insertion positions may be provided. In further developments, however such general grids with nxn or nxm positions conceivable, where n and m are each an integer.

In one embodiment, the luminaire as a whole can be finely adjusted, for example by finely adjusting the angular position of the entire luminaire in a limited angular range. This can be useful, for example, to make a fine adjustment or fine correction of the lighting effect achieved after mounting the lamp and thereby compensate for any installation tolerances.

In a preferred embodiment, the lighting segments are inserted at fixed positions and also relative to the lamp base body after insertion unadjustable or unjustierbar in the lamp base body, whereby the structure of the lamp is simplified and the lamp can be manufactured more cheaply. In this case, however, it is conceivable in a development that the luminous segments are each formed in one of a plurality of defined angular positions, for example rotated in steps of 90 degrees, so that they can be inserted into the lamp base body.

In one embodiment, the light output of the light segments can be selectively switched and / or controlled for individual light segments and / or for subgroups of the light segments such that different light effects can be achieved by means of the light. In particular, various possibilities are conceivable for switching on or off lighting segments individually or in combination with one another or for controlling the light output of the latter, in order to make a wide variety of lighting effects possible.

According to a development, the light output of the light segments can be switched and / or controlled in such a way that a plurality of light segments, in particular a plurality of identically formed light segments, a first subset of the light segments can be activated simultaneously to emit light to a first by co-operation of the light segments of the first subgroup To produce lighting effect, and further that a plurality of light segments, in particular a plurality of identically formed lighting segments, another subset of the light segments are simultaneously activated to emit light to produce by co-operation of the light segments of the further subgroup another light effect.

Here, the further light effect is different from the first light effect. In this way, different lighting effects can be effectively achieved by means of this adapted lighting segments. In a modification, some or all of the light segments combined in a subset may be differently designed if this is useful for producing the desired light effect.

In a development, the first and second subgroups of the light segments are disjoint. However, according to an alternative development, the first and second subgroups may instead comprise one or more common lighting segments.

In further embodiments, more than two subgroups of luminous segments may be provided for generating further light effects, for example three or four subgroups or even more.

In one embodiment, the lighting effects include a targeted, in particular direct, lighting a wall or a predefined area of a wall, and / or a targeted, in particular direct, lighting a floor or a predefined area of a floor, and / or a targeted, especially direct, Illumination of an object placed in a room or a person in a room.

It can thus be provided in one embodiment of the invention that by means of a subset of several equally shaped lighting segments, the wall or the predefined area of the wall can be illuminated, while by means of another subset of different, but in turn the same trained lighting segments of the floor or the predefined Area of the floor can be illuminated, wherein the two sub-groups for simultaneous lighting in the wall and floor area can be used in combination by appropriate switching and / or driving the lighting segments.

In other embodiments, however, it can be provided that the illumination of the wall or of the predefined area of the wall and / or the illumination of the floor or the predefined area of the floor and / or the illumination of the placed in the room object or the person in the room can each be done by means of a single, the light effect respectively associated luminous segment.

In a further embodiment, the lighting effects include a targeted, in particular direct, lighting a wall or a predefined area of a wall, and / or a targeted, in particular direct, lighting a floor or a predefined area of a floor, and / or a targeted, especially direct , Lighting a ceiling or a predefined area of a ceiling and / or a targeted, in particular direct, lighting an object placed in a room or a person in a room.

It can thus be provided in a further embodiment of the invention that by means of a subset of several equally shaped lighting segments, the wall or the predefined area of the wall can be illuminated, while by means of another subgroup of different, but in turn, the same trained lighting segments of the ground or the predefined area of the floor can be illuminated, while by means of yet another subset of, for example, turn different, but in turn with each other equally formed lighting segments, the ceiling or the predefined area of the ceiling can be illuminated. By appropriate switching and / or driving the lighting segments, the sub-groups for simultaneous lighting in the wall, floor and ceiling area can be used in combination.

In other embodiments, however, it may be provided that the illumination of the wall or the predefined area of the wall and / or the illumination of the floor or the predefined area of the floor and / or the lighting of the ceiling or the predefined area of the ceiling and / or lighting of the object placed in the room or of the person in the room can each take place by means of a single luminous segment assigned in each case to the light effect.

In a further development, the producibility of one or more of the light effects by means of a single one of the lighting segments with the producibility of another or several other of the lighting effects are combined by means of a subset of the luminous segments.

In one embodiment, the lighting segments each have a device which makes it possible to receive control signals for switching and / or controlling the light output of the luminous segment on a wireless or wired path. It can be provided in a further development facilities that allow the reception of the control signals both wired and wireless way. Here, the light segments are adapted to switch the light output according to the control signals and / or to control. In this way it is possible to address the lighting segments in a flexible manner and at the same time limit the cabling effort.

In one embodiment, the lighting segments each have a communication device, which allows receiving the control signals wirelessly and in particular includes an interface for communication via a wireless protocol. Alternatively or additionally, the lighting segments may each have an interface for connection to a wired bus or a wired network, which allows receiving the control signals.

In one embodiment, an outer contour of at least one of the luminous segments, some of the luminous segments or all of the luminous segments is polygonal, in particular rectangular or square. Alternatively, an outer contour of at least one of the luminous segments, some of the luminous segments or all of the luminous segments may be round, in particular circular. In a further alternative embodiment, an outer contour of at least one of the luminous segments is round, in particular circular, and an outer contour of at least one further of the luminous segments is polygonal, in particular rectangular or square. For example, an interesting aesthetic effect can be achieved if the lighting segments all have a relatively simple, for example the same, outer contour, but are different in terms of their emission characteristics. A rectangular outer contour may also be advantageous for inserting a plurality of luminous segments into a substantially rectangular luminaire base body.

In developments of the invention, the luminaire can be designed for arranging the luminaire in the ceiling area and / or for arranging the luminaire in the wall area.

In one embodiment, the lamp is designed as a grid lamp for arrangement in a grid ceiling. Advantageously, it is thus possible, even in cases in which orient the arrangement and attachment of the lamp by way of example to the grid of a grid ceiling to provide lighting effects in a flexible and versatile manner.

In an alternative embodiment, the luminaire is designed as a recessed luminaire. In this case, the luminaire may be provided and furnished, for example, for installation in a ceiling and / or for installation in a wall.

According to a further alternative embodiment, the luminaire is designed for use as a suspended luminaire, wherein the luminaire may have, for example, an independent housing for use as a suspended luminaire.

In a further alternative embodiment, the lamp is designed for mounting on a wall. For this purpose, the lamp may in particular have an independent housing, which makes it possible to arrange the lamp in the wall area on the surface of the wall. Alternatively, the luminaire could be designed for mounting on a surface of a ceiling and in particular have a self-contained housing, which is arranged for arranging the luminaire on the surface of the ceiling.

In this way, a wide variety of lighting requirements can be met.

In one embodiment, the lighting segments are each equipped with an LED or an LED arrangement for generating light. In this way, an energy-efficient and durable lamp can be provided.

The above embodiments and developments can, if appropriate, combine with each other as desired. Further possible refinements, developments and implementations of the invention also include combinations of features of the invention which have not been explicitly mentioned above or described 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.

They illustrate embodiments and, together with the description, serve to explain principles and concepts of the invention. Other embodiments and many of the stated advantages will become apparent with reference to the drawings. The elements of the drawings are not necessarily shown to scale to each other.

DESCRIPTION OF EMBODIMENTS

Fig. 1 shows a lamp 1 according to a first embodiment. Further shows Fig. 1 a space 2 in a building not shown in its entirety, wherein the space 2 in the embodiment shown has a relatively narrow and elongated shape. The room 2 may be, for example, a Walk inside the building. However, room 2 may also be a different type of space, for example an office space, a business premises, etc. The space 2 has a grid ceiling 3, which forms a suspended false ceiling. Furthermore, the space 2 has a first wall 4a, a second wall 4b and a bottom 5. The lamp 1 is designed as a grid lamp for mounting in the grid ceiling 3 and in the in Fig. 1 not shown in detail, but only hinted grid ceiling 3 attached.

The luminaire 1 has a square luminaire base body 6 and a plurality of luminous segments 7 and 8 which can be inserted into the luminaire base body 6, wherein in FIG Fig. 1 the lighting segments 7 and 8 are inserted at predefined positions 7a and 8a in the lamp base body 6, see also Fig. 1A , For the sake of clarity, in Fig. 1 and 1A not all of the light segments and positions provided with reference numerals. By way of example, the luminaire 1 of the Fig. 1, 1A four lighting segments 8 and twelve light segments 7 on. An outer contour 9 of each of the light-emitting segments 7 is in Fig. 1 square shaped. By contrast, an outer contour 10 of each of the light segments 8 is circular. The outer contours 9 of the luminous segments 7 and the outer contours 10 of the luminous segments 8 are each formed the same.

Fig. 1 and 1A show, moreover, that the positions 7a of the light-emitting segments 7 and the positions 8a of the light-emitting segments 8 are each arranged regularly. While the luminous segments 8 are arranged along a straight line, the luminous segments 7 are arranged at positions 7a corresponding to the crossing points of an orthogonal grid. In the first embodiment, however, the positions 8a also form further crossing points of the grid, which already defines the positions 7a, see Fig. 1A ,

The light segments 7 and 8 thus form in their inserted state, see FIGS. 1A and 2 , an assembly 80 extending in a plane E. The plane E runs in Fig. 1, 1A and 2 in the mounted state of the luminaire 1 shown there, horizontal and parallel to a plane in which the grid ceiling 3 extends, wherein the plane E and the plane of the grid ceiling 3 can coincide. A horizontal direction H with respect to the space 2 is shown in FIG Fig. 1 located. The plane E will thus, see FIGS. 1A and 2 , spanned by two directions R1, R2, in the Fig. 1A perpendicular to each other and parallel to the grid ceiling 3, or in the plane of the grid ceiling 3, extend.

The lighting segments 7 and 8 are each designed to be inserted into the lamp base body 6 and thereby inserted in this particular releasably. For example, the lighting segments 7, 8 and / or the lamp base body 6 may be provided with suitable locking means, by means of which it can be achieved that the lighting segments 7 and 8 each engage in the insertion into the lamp base body 6 and thus, in particular releasably, are held. It can be provided that the latching insertion of the light-emitting segments 7, 8 each in several rotational positions, for example in multiple layers twisted about an axis parallel to the vertical axis V, and in particular normal to the plane E, through the center of the luminous segment, allows. Latching insertion could be possible in a plurality of steps offset by a predefined angle, e.g. in steps of 90 degrees.

The light segments 7 and 8 are formed in the first embodiment as exchangeable emitters, in particular spots. Each of the light-emitting segments 7, 8 thus emits light in a directed manner and has a predefined radiation characteristic. However, the emission characteristics of the luminous segments 7, 8 of the luminaire 1 are not all identical, but the total quantity of the emission characteristics of the luminous segments 7, 8 comprises a plurality of different emission characteristics.

Each of the light-emitting segments 7, 8 has one or more light sources which enable the directed emission of light by the light-emitting segments 7, 8. The light output of the light segments 7, 8 is in the lamp 1 of Fig. 1 specifically at least in the FIGS. 1 to 4 schematically illustrated manner switchable and / or controllable to produce several different lighting effects. The switching and / or controlling the light output of a light segment 7, 8 may in particular include a complete shutdown of the light segment, turning it on at full power, as well as, if necessary, turning on the light segment at a predefined power level below full power. Furthermore, can the switching and / or controlling the light output additionally comprise a stepless regulation of the light output in the sense of dimming.

In Fig. 1 is the provision of a first light effect 11 schematically sketched by means of the lamp 1 according to the first embodiment. For this purpose, two lighting segments 7, which are additionally provided with the reference numeral 7 'for better identification, are activated, while the other lighting segments 7, 8 are switched off. The two light segments 7 'each have a radiation characteristic which makes it possible, by means of the two light segments 7' together to produce a light distribution which enables direct illumination of a predefined region 11a of the bottom 5 of the passage 2. For this purpose, it is useful if the light-emitting segments 7 'produce an elongated light distribution which is better adapted to the elongated shape of the space 2 than a circular cone of light. With one lamp 1 thus efficient illumination is possible.

In Fig. 2 instead of the light segments 7 'a single light segment 7, in Fig. 2 7, 8 are activated, while the other lighting segments 7, 8 are switched off The radiation characteristic of the light segment 7 "differs from that of the lighting segments 7 '. The light-emitting segment 7 "produces a round, for example circular or elliptical, light distribution in the area 12a as a second light effect 12 at the bottom 5. In contrast to, for example, greater-area illumination of the floor 5, as in FIG Fig. 1 , is in Fig. 2 created a different mood by the light effect 12 and the room 2 differently than in Fig. 1 staged. In Fig. 2 becomes a smaller and differently shaped predefined area 12a of the bottom 5 than in FIG Fig. 1 directly lit. It may be in the room 2 optionally an object O, in Fig. 2 dashed lines are located, which stands for example on the floor 5 and is particularly illuminated and staged by the light effect 12. Instead of the object O, a person in room 2 could be illuminated by means of the activated light segment 7 ".

In Fig. 3 are two marked with the reference numeral 8 'of the light segments 8 and two marked with the reference numeral 7''' of the light segments 7 is activated to produce a third light effect 13. The third light effect 13 includes two individual light effects 13 'and 13 "and includes direct illumination both walls 4a, 4b of the room 2 in rather elongated illuminated areas 13a, 13b, but without the bottom 5 is specifically illuminated directly. This in turn creates a changed mood in room 2. If present, objects located on the walls may be illuminated, or only the wall surface and structure are illuminated to set room 2 in scene.

In Fig. 4 is the light output of the light segments 7, 8 of the lamp 1 switched in the manner and / or controlled that in the Fig. 1, 2 and 3 schematically outlined lighting effects are combined and thus form a fourth light effect 14. The fourth light effect 14 thus combines the direct illumination of the walls 4a, 4b as in Fig. 3 with the illumination of the bottom 5 according to Fig. 1 and with a thus enhanced illumination of a circular or elliptical region 12a of the bottom 5, within the bottom region 11a already illuminated by means of the luminous segments 7 '.

To those in the Fig. 1, 2 . 3 and 4 to produce schematically illustrated light effects 11-14, individual of the light segments 7, 8 of the lamp 1 or subgroups of the light segments 7, 8 selectively switched on or off or controlled their light output targeted.

In Fig. 1 form the light segments 7 ', which may be similar, a first subgroup 21 of light segments 7, which are activated simultaneously to produce the first light effect 11 by cooperation of the light segments 7' of the first subgroup 21. On the other hand, in Fig. 2 activates a single light segment 7 "for generating the second light effect 12.

In Fig. 3 the luminous segments of a second subgroup 22, which comprises two luminous segments 8 'and two luminous segments 7'", were seen Fig. 3 activated simultaneously to produce the third light effect 13, wherein a third subgroup 22a comprising the two, for example, similar luminous segments 8 ', the illumination of the area 13a on the first wall 4a and a fourth subgroup 22b, comprising the two, for example, similar luminous segments 7'' which illuminates the area 13b on the second wall 4b Luminous segments 8 'of the third subgroup 22a together produce the light effect 13' on the first wall 4a, while the luminous segments 7 '''of the fourth subgroup 22b together produce the light effect 13 "on the second wall 4b "the third light effect 13 is formed.

In Fig. 4 the sub-groups 21, 22a, 22b and the light-emitting segment 7 "are simultaneously activated in order to provide the light effect 14. The light-emitting segments 8 ', 7', 7", 7 '"form the in Fig. 4 schematically outlined fourth subgroup 23.

Based on Fig. 1-4 It can be seen that the light effects 11, 12, 13 'and 13 "are different from each other, and the light effects 13 and 14 are different from the individual light effects 11, 12, 13', 13" by combining some or all of the light effects , 12, 13 ', 13 ", other lighting effects are created The sub-groups 21, 22a, 22b are disjoint and thus do not contain common lighting segments, whereas the sub-groups 21, 22a and 22b are all included in the fifth sub-group 23.

It thus becomes apparent that the luminaire 1 advantageously enables the generation of light effects, in particular in vertical and horizontal subregions or areas of the room 2, by way of example in the region of the bottom 5 and the walls 4a, 4b, without pivoting or to vary the light effects Twisting spots would be necessary. The light segments 7, 8 radiate from the horizontally extending array 80 into the space 2, for example, to one or more areas of the walls 4a and / or 4b or the entire wall 4a and / or 4b, and alternatively or in combination therewith It is so with a permanently mounted lamp 1 with horizontally laid out in the mounted state, fixed arrangement 80 of the light segments 7, 8 different lighting effects in the horizontal and in particular in the vertical can be generated. The variation of the light effects takes place here in a simple manner by switching and / or controlling the light output of individual light segments 7, 8 or of groups of these.

Each of the light-emitting segments 7 and 8 has, according to the first embodiment, an optical component 25 formed as a reflector 30, below which Use each of the radiation characteristics of the luminous segment 7, 8 is achieved. In order to achieve different emission characteristics, the luminaire 1 is equipped with luminous segments 7 and 8 in such a way that the luminaire 1 contains different such reflectors 30. The luminaire 1 has luminous segments 7, 8 with at least two different reflector types for generating at least two different emission characteristics in order to be able to provide different light effects.

Fig. 5 and 5A schematically show a reflector 30 for a luminous segment 7 of the lamp 1 according to the first embodiment. The luminous segment 7 can be, for example, one of the luminous segments 7 'of the first subgroup 21.

The reflector 30 is manufactured, for example, by means of injection molding and has a plurality of light-reflecting partial surfaces 31, 32, 33, 34, 35, 36, 37, 38. Alternatively, however, the manufacture of the reflector 30 could alternatively be done by means of another manufacturing process, for example by forming a sheet metal blank. The two light-reflecting partial surfaces 31 and 33 are arranged opposite one another and are each formed as part of a standard reflector surface. Furthermore, the two light-reflecting partial surfaces 32 and 34 are arranged opposite one another and are each designed as a free-form surface. With the help of the free-form surfaces 32 and 34, it is possible to influence the emission characteristic of the luminous segment, which is equipped with the reflector 30, in a targeted manner.

In Fig. 5 Furthermore, a light source 49 is schematically illustrated by way of example, which in this exemplary embodiment is designed as an LED arrangement 50 with a plurality of light-emitting diodes (LEDs) 51. The LED arrangement 50 forms, like the reflector 30, a component of a luminous segment and is in Fig. 5 exemplified quadrangular, but it should be noted that the light source 49 may be different, for example, round, shaped. Furthermore, instead of LEDs, other light sources, such as halogen lamps, conceivable.

Furthermore, in Fig. 5 a in the lamp base body 6 inserted state of the luminous segment the space 2 facing visible side S of the reflector 30 indicated. The reflector 30 opens to the visible side S back to emit the light with the desired radiation characteristics. Fig. 5A shows the reflector 30 schematically in plan view from the visible side S ago.

The reflector 30 has four light-reflecting sides 30a, 30b, 30c, 30d, wherein adjacent ones of the light-reflecting faces 31-38 are connected to each other at one of a plurality of corners 39a-39d of the reflector 30. In detail, the partial surfaces 31 and 32 and 35 and 36 are connected to each other at the corner 39a, the partial surfaces 32 and 33 and 36 and 37 are connected to each other at the corner 39b, the partial surfaces 33 and 34 and 37 and 38 are respectively the corner 39c connected to each other, and the partial surfaces 34 and 31 and 38 and 35 are connected to each other at the corner 39d. The reference numeral 30u designates the substantially rectangular, in particular square, outer contour of the reflector 30.

Fig. 5 also shows a central axis A of the reflector 30. The light-reflecting faces 31-38 enclose a reflector inner region 40, which tapers like a funnel, but with a polygonal cross-sectional shape with the four corners 39a-d to the LED assembly 50. The further towards the visible side S down, light-reflecting faces 35-38 are more inclined to the central axis A, thus, viewed from the visible side S from flatter, and together form a significantly larger opening angle than the light-reflecting faces 31-34.

The formed as free-form surfaces faces 32 and 34 are formed bulged toward the reflector inner area 40 towards bulbous. The bulbous protrusion is in Fig. 5 and 5A designated by the reference numeral 45. Such a design of the free-form surfaces 32, 34 is particularly useful for adapting the light distribution and radiation characteristic of a luminous segment having the reflector 30, for example, to an elongate area to be illuminated. 6 and 7 illustrate schematically a cone of light 60, as it by means of a reflector 30 with light-reflecting faces 31-38 according to Fig. 5, 5A can be generated in two mutually normal directions. In detail shows Fig. 6 a schematic side view of the light cone 60, while Fig. 7 this shows from the front. It becomes clear that the light cone 60 differs in the two viewing directions is shaped and, in particular Fig. 7 makes clear, has an elongated shape. This allows easier and more efficient illumination of elongated premises such as corridors, see Fig. 1-4 ,

The shape of the light-reflecting faces 31-38 illustrate schematically and in a simplified manner in addition the 8 and 9. Fig. 8 shows the trained as a standard reflector surfaces, running with parabolic shape and in particular provided with a facet structure part surfaces 31 and 33 in a central section II through the reflector 30, see. Fig. 5A , In which to cut the Fig. 8 normal midline II-II of the Fig. 9 , see. Fig. 5A , the partial surfaces 32 and 34 formed with bulbous protrusions towards the reflector inner region 40 are schematically simplified, as are the schematically indicated cutting lines (shown in dotted lines) of the partial surfaces 32 and 34 with the other two partial surfaces 31 and 33 in the region of the corners 39a-d of the reflector 30th

Although the shape of the reflector 30 can not be changed by a user, a number of different reflector shapes are preferably provided, by means of which the emission characteristic of the luminous segment can be suitably modified for different light effects. For some of the light segments, for example the light segment 7 "of Fig. 2 A user can, for example, in the initial configuration of the lamp 1 light segments 7, 8 from a variety of available light segments with different or the same outer contour and Assemble different reflector shape to meet the desired use. For example, different reflectors 30 could be provided for the illumination of aisles of different widths.

The Fig. 1-4 However, the luminous segments 7 may have different reflector shapes, in other words, the shape of the reflector of the luminous segment 7 'differs from that of the reflector of the luminous segment 7 ", which in turn depends on the shape of the reflector of the luminous segment The same outer contour 9 is not only aesthetically interesting, but also facilitates the combination of light segments 7 with different radiation characteristics, especially since the outer contour 9 does not vary. If the luminaire 1 is configured by selecting luminous segments from a larger number of available luminous segments, the substantially identical outer contour 9 can prove to be practical. With an identical outer contour 9, the outer contours 30u of the associated reflectors 30 can also be the same, for example for all of the luminous segments 7 of FIG Fig. 1-4 even though the design of the patches 31-38 varies to provide different radiation characteristics.

The above comments on the design of the reflector 30 are analogously applicable to the light-emitting segments 8 with the outer contour 10, in which case the reflector z. B. may have a round outer contour.

The releasably inserted light segments 7 and 8 are each interchangeable, whereby even if necessary, even after the choice of the initial configuration changes to the lighting effects are possible and also a damaged light segment can be easily replaced by a new if necessary.

The lamp 1 can as a whole in the assembled state of Fig. 1-4 be fine tuned or adjustable, such as for fine adjustment of the overall orientation of the lamp 1 and to compensate for mounting tolerances. This can be done by pivoting the lamp 1, for example, about the two axes A ', A ", see Fig. 1 , in particular within a limited angular range, take place. However, it can alternatively be dispensed with such adjustability of the lamp 1, which further simplifies the construction of the lamp 1.

As mentioned, the lamp 1 according to the first embodiment is designed as a grid lamp. The luminaire base body 6 is dimensioned in such a way that it can be suitably accommodated in a grid of the grid ceiling 3. This illustrates schematically the Fig. 10 , which also shows profile elements 3a of the grid ceiling 3 schematically. The lamp base body 6, which may in particular comprise a suitable housing, may also be equipped with suitable means for holding the lamp 1 in a grid of the grid ceiling 3 formed by the profile elements 3a.

An in Fig. 11 sketched second embodiment differs from the first embodiment only in that the lamp 1 'instead of a grid lamp is designed as a recessed light. For this purpose, the luminaire 1 'may have a luminaire base body 6' which is adapted to the installation situation and which in turn may be formed with a suitable housing. A ceiling 3 'of the space 2 may for example have a suitable recess for receiving the lamp base body 6'. In the case of the ceiling 3 ', one example may also be a suspended false ceiling, which, however, in this example does not form a grid ceiling.

A third, in Fig. 12 sketched embodiment differs from the first embodiment only in that the lamp 1 "is formed in a suitable manner and in particular has a suitably designed lamp base body 6" to be used as a suspended lamp 1 " Fig. 12 has the lamp base body 6 "an independent housing, which remains visible after hanging the lamp 1". In Fig. 12 is the lamp 1 "suspended by way of example on ropes on a ceiling 3" of the room 2. However, the lamp 1 "may instead be suspended from the ceiling 3" by other suitable means.

A schematically greatly simplified representation of a luminous segment 7 or 8 for the luminaires according to the embodiments described above shows the Fig. 15 In addition, wherein a section of the luminaire base body 6, 6 'or 6 "is shown schematically and simplified, the luminous segment 7, 8 has the optical component 25, the light source 49, for example in the form of the LED arrangement 50, an arrangement 100 electrical and electronic components for the supply and control of the light source 49, comprising in particular a converter, latching devices 110 for mechanical attachment and holding the light segment 7, 8 in the lamp base body 6, 6 ', or 6 "and electrical contacting devices 120 in particular for establishing an electrical connection with a Power supply, for example, at mains voltage, z. B. 230 V, on. The luminaire base body 6, 6 'or 6 "is in turn provided with light-base body-side latching devices 111 and electrical contacting devices 121. The latching devices 111 are configured to latch with the latching devices 110 to engage the lighting segment 7 or 8 on the lamp base body 6, 6 ', or 6 ", while the electrical contacting means 121 are adapted to contact the contacting means 120 and make an electrically conductive connection To provide the lighting segment 7, 8 with electric power. For this purpose, in the lamp base body 6, 6 ', or 6 "electrical supply lines may be provided, the sake of clarity in Fig. 15 not shown in detail.

The components of the arrangement 100, the light source 49 and the contacting means 120 could, for example, be arranged on a common circuit board or instead be provided separately in a suitable housing.

In further embodiments of the invention, instead of the reflector 30, as described for the preceding embodiments, a lens may be used as optical component 25 to influence the emission characteristic of the respective luminous segment 7, 8. A lens 130 and a lens 230, which can be used by way of example in corresponding modifications of the first to third embodiments for influencing the radiation characteristic, are shown in FIGS FIGS. 16 and 17 shown schematically, it being understood that the lens 130 and 230 can be adjusted with respect to material and geometry to the respective desired light effect and the desired radiation characteristic of the luminous segment 7 and 8 respectively.

The lens 130 according to a fourth embodiment, see Fig. 16 , has on a front-side front side 135, which corresponds to a visible side S and on which the lens 130 in the use state in the lamp 1 emits light, a plate-shaped portion 131 whose outer contour in the example of Fig. 16 at the same time defines the outer contour 131 u of the lens 130. In the example of Fig. 16 is the outer contour 131 u of the lens 130 square, but it is conceivable, in modifications of the example of Fig. 16 To provide lenses with a round, for example circular, outer contour 131 u. The choice of the outer contour 131 u may also depend in the case of the use of lenses on how the positions 7a, 8a are provided in the lamp base body 6 and which outer contour 9, 10 the respective Should have light segment. Fig. 16 shows the lens 130 together with its indicated center axis AA.

To influence the emission characteristic, which is achieved using the lens 130, the lens 130 has a recess 132 on the front side 135 in the center, which is provided for setting the emission characteristic and thus serves as an optical system for controlling or influencing the emission characteristic. The recess 132 is thus at the lens 130 of Fig. 16 depending on the desired radiation characteristic of the luminous segment, which is equipped with the lens 130 is formed.

On one of the plate-shaped portion 131 opposite rear side 136 of the lens 130, this has a further recess 133, in which in the use state of the lens 130 in the light segment 7 or 8, the light source 49, preferably an LED or LED array is arranged.

Furthermore, the lens 130 has two fixing sections 134 on the rear side 136, which are designed, for example, as bolt-shaped or suppository-type and serve for fixing the lens 130, in particular on a circuit board. Other types of fixation of the lens 130 in the light segment 7, 8, in particular on a circuit board, which also carries the LED or LED array, however, are conceivable.

In a variant of the fourth embodiment, instead of the lens 130, a lens 230, see FIG Fig. 17 , be provided. The lens 230 of the Fig. 17 differs from the lens 130 of the Fig. 16 merely in that the lens 230 on the front side 135 is not provided with a recess 132 for influencing the emission characteristic. If the desired radiation characteristic of the luminous segment 7 or 8 does not require a recess 132, this can thus be omitted.

According to the above-described fourth embodiment and the explained variant thereof, the luminous segments 7 and the luminous segments 8 each have a lens 130 or 230 instead of the reflector 30. If necessary, the lighting segment 7, 8 is then suitably set to the lens 130 or 230 in place to fix the reflector in a suitable manner. In addition, however, the lamp according to the fourth embodiment and its variant is formed as described above for the first embodiment, wherein the lights according to the fourth embodiment and its variant as explained in the second and third embodiments above can be modified.

A luminaire 1001 'according to a fifth embodiment and a luminaire 1001 "according to a sixth embodiment show the FIGS. 18 and 19 , The lamps 1001 'and 1001 "each represent modifications of the embodiments described above and their variants, so that reference is made to the above explanations except for the differences explained below.

The luminaire 1001 'is installed in the wall area in a room 1002. The space 1002 comprises a ceiling 1003, a floor 1005, and at least a first wall 1004a and a second wall 1004b 'opposite thereto. The luminaire 1001 'is installed in the second wall 1004b', the luminaire 1001 'for this purpose having a luminaire base body 1006' adapted to the installation situation in the wall 1004b '. The lamp base body 1006 'is in the embodiment of Fig. 18 formed with a housing which is adapted for installation in the wall 1004b '. The luminaire base body 1006 'is in Fig. 18 received in a suitable recess in the wall 1004b 'and held by means not shown holding means.

In the sixth embodiment of the Fig. 19 For example, the luminaire 1001 "is also installed in the wall area. Again, the space 1002 has two walls 1004a and 1004b". On the surface of wall 1004b "the lamp 1001" is mounted. For this purpose, the luminaire 1001 "is designed and in particular has a luminaire base body 1006" in order to be used as a surface or surface luminaire 1001 " Fig. 19 has a self-contained housing, which remains visible after mounting the lamp 1001 "on the wall 1004b".

As well in Fig. 18 as well as in Fig. 19 the generation of a light effect 1011 on the first wall 1004a is shown schematically. It is understood, however, that means the lamp 1001 'and the lamp 1001 "each, analogously to the generation of light effects by the lights 1, 1', 1", different lighting effects can be generated. Here, in the embodiments of the Fig. 18, 19 In addition, by means of suitable lighting segments 7, 8 light effects not only on the wall 1004 a, but also on the floor 1005 and / or on the ceiling 1003 are generated. Reference should be made to the above statements.

In the case of the luminaire 1001 ', the luminous segments 7 and 8 thus form in their inserted state, see Fig. 18 an arrangement extending in a plane E ', the plane E' in Fig. 18 in the mounted state of the lamp 1001'vertikal and parallel to a plane in which the wall 1004b 'extends extends. In the case of a built-in lamp 1001 ', the plane E' and the plane of the wall 1004b 'may coincide. The plane E 'is defined by two directions R1', R2 ', which in Fig. 18 perpendicular to each other and parallel to the wall 1004b ', or in the plane of the wall 1004b', extend. Also with the lamp 1001 "the Fig. 19 the light-emitting segments 7 and 8 form an arrangement which is in an in Fig. 19 not shown vertical plane parallel to the wall 1004b "extends.

In particular, it should be mentioned that the above remarks to Fig. 15 also applicable to the lamps 1001 ', 1001 ".

The above-described switching and / or controlling the light output of the light segments 7, 8, individually, combined in disjoint and / or overlapping subgroups, or all together, can in a non-illustrated variant of all the embodiments described above by leading to the individual light segments, live cable and switch or dimmer done. For this purpose, subgroups to be switched, for example, can already be defined during the installation of the luminaire 1, 1 ', 1 ", 1001', 1001", and a suitable number of switches or dimmers can be provided for these subgroups. The electrical connection of the light segments 7, 8 with the switches or dimmers then determines whether and how the light segments 7, 8 can all be switched or controlled together or individually or in subgroups with regard to their light output.

In a further variant of the embodiments described above, however, the switching and / or controlling the light output of the light-emitting segments 7, 8 takes place in a in Fig. 13 schematically sketched manner mediated via a bus 70. Each of the lighting segments 7, 8 is connected for example to a power supply, which in Fig. 13 not shown in detail. The activation, deactivation or dimming of the light segments 7, 8 takes place in the variant of Fig. 13 For example, with the help of the light segments 7, 8 associated addresses and / or a suitable protocol and in a suitable form over the bus 70 transported control and / or switching instructions. The light segments 7, 8 can thus be addressed in a particularly flexible and variable manner. Alternatively, instead of the bus 70, a control network can be used. Each of the light segments 7, 8, see Fig. 13 , has a device 71, which makes it possible to receive control signals for switching and / or controlling the light output of the light segment 7 or 8 via a wired path via the bus 70. Here, the device 71 comprises an interface for connection to the bus 70. Alternatively, the interface may be designed for connection to a wired network.

In a further preferred variant of the embodiments described above, the control and / or the switching of the light output of the individual light segments 7, 8 is not wired, but wirelessly, which avoids the laying of cables. This is in Fig. 14 sketched schematically. Each of the light segments 7 and 8 has a communication device 72, which allows receiving control signals for switching and / or controlling the light output by wireless route. In particular, the communication device 72 comprises an interface for communication via a wireless protocol.

It should be noted that in addition to the means 71 or 72 of each of the light-emitting segments 7, 8 may also have a computing device for processing the control signals and a driver component, which allows the variation of the radiated light output corresponding to the control signals.

The devices 71 and 72 as well as the computing device and the driver component can be part of the in Fig. 15 be schematically indicated arrangement 100.

It should also be mentioned that in the embodiments described above, the luminous segments 7, 8 and the luminaire base body 6, 6 ', 6 ", 1006' and 1006" contacting means 120, 121, see Fig. 15 , which are not only suitable for making electrical contact of the light-emitting segments 7, 8 with a power supply, but, if a wired control is to be possible, additionally make it possible, for example, to make contact with a data line, for example for the bus 70, manufacture. Alternatively, it would be conceivable to provide separate contacting means for the data line.

Although the present invention has been fully described above with reference to preferred embodiments, it is not limited thereto but is modifiable in a variety of ways.

In particular, the invention is not limited to a luminaire having the number and combination of luminous segments specified in the exemplary embodiments. It could be provided more or less light segments, which, for example, all may have a rectangular or square outer contour. Many numbers and combinations of light segments are conceivable.
