    DESCRIPTION The invention relates to a luminaire for a vehicle interior and to a lighting module comprising such a luminaire.
    Luminaires for the interior of a vehicle are known in practice, for example in the form of LED (light-emitting diode) luminaires for an aircraft cabin. In these fixtures, discrete LED components are mounted on printed circuit boards. For color systems, systems made up of individual LEDs of different colors are used (for example, respective RGBW LEDs, R: red G: green B: blue W: white).
    The object of the invention is to provide an improved luminaire. To this end, the invention provides a luminaire for an interior of a vehicle, containing a base body for attachment to the vehicle and at least one light source attached to the base body, characterized in that at least one of the sources of light is a matrix LED, the matrix LED having at least two LED pixels which can be activated independently of one another, the LED pixels being integrated on an LED chip. The invention may also relate to one, several or all of the following additional characteristics or variant embodiments, in relation to the luminaire mentioned above: - at least one of the matrix LEDs is a matrix LED which generates a monochromatic light in operation and / or at least one of the matrix LEDs is a matrix LED which generates a modifiable color light in operation, - the matrix LED has a characteristic dimension of at most 20 mm, preferably at most 15 mm , preferably at most 10 mm, preferably at most 6 mm, preferably at most 4 mm and / or at least 4x4, preferably at least 8x8, preferably at least 16x16, preferably at least 32x32 pixels LED (14), - the luminaire is a linear luminaire which extends along a longitudinal axis and which contains at least two light sources, at least two of the light sources being arranged side by side removes in the direction of the longitudinal axis, - the luminaire is a flat luminaire which contains at least three light sources, at least three of the light sources being arranged side by side and distributed in two dimensions, - the luminaire contains an overlap which has a potential passage area for the light of at least one of the matrix LEDs and which is at least partially transparent in this passage area, - the luminaire does not have, in the whole of the potential emission area of at least one of the matrix LEDs, no element modifying in a variable manner the light emitted by it, - the luminaire contains a configuration means in which it is possible to define a configuration to activate the LED pixels of at least one of the LEDs matrix, - the luminaire has a control input by which, in normal operation, at least one of the LED pixels of one of the matrix LEDs can be activated, - the luminaire (2) is a luminaire (2) for an interior (4) in the form of a passenger cabin and / or for a vehicle (6) in the form of an airplane.
    As mentioned previously, the luminaire according to the invention contains a basic body. The base body is used to fix the base body and therefore to fix the entire luminaire to the vehicle. The luminaire contains at least one light source. The light source is attached to the base body. At least one of the light sources is a matrix LED. The matrix LED has at least two LED pixels. The LED pixels are integrated into an LED chip. The pixels can be controlled or activated independently of one another, in particular on and off, and optionally varied, independently of one another. The invention is based on the observation that matrix LEDs, also called "segmented LEDs on a chip", are currently being developed for use in matrix projectors for automobiles. The objective here is a dynamic adaptation of the passing or driving beam and the adaptive limitation of the glare of oncoming traffic. The developed matrix LEDs generate white light. The invention is also based on the observation that this principle should be transferable to the manufacture of color matrix LEDs. Such matrix LEDs are known, for example, from '' 3000 Pixel pro Autoscheinwerfer '(' 3000 Pixels per automotive headlight '), VDI-
    Nachrichten, n ° 47, 25.11.2016, p.19 ”or from“ 'Bessere Sicht bei Nachtfahrten' ('Best view during night driving'), Fraunhofer Forschung Kompakt, March 2016, p.l ”. The invention is based on the array LEDs described above, or at least on LEDs which are analogous to those described above and have LED pixels which can be activated individually in an ID or 2D matrix, for example 32 × 32 pixel LEDs on a 4 mm x 4 mm chip. According to the invention, such matrix LEDs or comparable technologies are contained in a luminaire for a vehicle interior, in particular an aircraft cabin. A "comparable technology" would be, for example, a matrix LED with only one column or row, therefore a "linear LED", in which a large number of pixels, for example at least 16, 32, 64, 128 or 256 pixels are integrated on an LED chip not in the manner of a 2D matrix but in a linear ID arrangement.
    In the context of the present invention, a matrix LED is an integrated optoelectronic component. In it, a plurality of LEDs are integrated on a chip. The individual LEDs are arranged in the form of an array and each form a pixel. In other words, a matrix LED is an integrated multi-pixel LED chip produced by micro-structuring. The integration of LEDs on a chip makes it possible to greatly reduce the size compared to a corresponding arrangement of individual LEDs. Thus, a larger number of LEDs or pixels can be arranged in the same space. The activation of individual LEDs or pixels is carried out with appropriate digital control electronics, similar to a display. Compared to an arrangement of individual LEDs, where each one needs its own line for its activation, significantly fewer lines are necessary to activate the matrix LED located on a chip.
    According to the invention, there is provided a luminaire whose lighting characteristic can be adapted in two directions of space in the case of a 2D matrix LED or in one direction of space in the case of a line. ID. This adaptation is carried out by switching on / off / selective variation of the individual pixels of the matrix LEDs used. This consideration initially applies to matrix LEDs with monochromatic emission. For matrix LEDs with emitters of several colors, it is also possible to produce luminaires with full color capability by mixing colors. Adapting the lighting characteristic in two directions of space in this case means not only the characteristic of the brightness emitted, but also of the color of the light generated. Depending on the type of luminaire (spot, reading lamp, linear luminaire, flat luminaire, ...), it is possible to install at least one and up to a large number of matrix LEDs in a luminaire.
    According to the invention, the lighting characteristic of linear luminaires as well as spotlights / reading lamps, etc. can be adapted without mechanical adjustment by appropriate activation of the finished luminaire or of the matrix LEDs (activation different from the individual pixels), the individual pixels being suitably activatable individually or independently of one another. It can also mean that certain pixels are never used.
    According to the invention, the use of matrix LED components results in an extension of the possibilities of use and design of LED-based luminaires to the fields described. According to the invention, this therefore results in a matrix LED luminaire. The use of segmented LED matrix LEDs in aircraft cabin luminaires allows static or dynamic adaptation of the emission characteristic by corresponding activation of the individual pixels of the matrix LEDs. This generally applies to all interior vehicle luminaires.
    Another advantage of the invention is that energy is consumed only when the LED pixels are on. Compared to the concealment or attenuation of light components already generated by mechanical measurements or even compared to the use of projectors, this makes it possible to obtain increased efficiency and the associated advantages.
    In a preferred embodiment of the invention, at least one of the matrix LEDs is an LED which generates monochromatic light in operation. As a variant or in addition, at least one of the matrix LEDs is an LED which generates a light of color which can be modified in operation. In the first case, the matrix LED is therefore an LED intended to emit monochromatic light. This light can be white, but also of any color, for example red or green. The color of the light cannot however be changed during operation.
    Preferably, however, the color of the light is changeable. This is achieved, for example, by LED pixels of different primary colors, i.e. allowing the generation of light of different color. For example, pixels R, G, B and W are present on an LED chip. A different activation of the respective pixels produces a light of corresponding mixed colors, both the brightness and the color of the light being modifiable in operation.
    Economic luminaires (monochromatic light) or luminaires for particularly variable use (multichromatic light or variable in terms of color and brightness) can thus be created.
    In a preferred embodiment, the matrix LED has a characteristic dimension of at most 20 millimeters, preferably at most 15 millimeters, preferably at most 10 millimeters, preferably at most 6 millimeters, preferably not more than 4 millimeters. As a variant or in addition, the matrix LED has at least 4x4, preferably at least 8x8, preferably at least 16x16, preferably at least 32x32 pixel LEDs in a planar 2D layout. A characteristic dimension is, for example, a length, width, diameter or maximum lateral extension of an LED chip, each time with reference to the active LED surface, that is to say the surface covered with LED pixels .
    Such matrix LEDs are therefore relatively small compared to the arrangements with conventional individual LEDs and have a large number of LED pixels, for example 1024 pixels, which are arranged in particular in the form of a 2D matrix. The individual or independent activation of the individual pixels makes it possible to achieve particularly varied light-emitting characteristics of the matrix LED, in particular to emit light selectively in certain directions of space, not to emit light or to emit it at the desired brightness.
    In a preferred embodiment, the luminaire is a linear luminaire which extends along a longitudinal axis and which contains at least two light sources, at least two of the light sources being arranged side by side or in series in the direction of the longitudinal axis. In particular, all the light sources are arranged side by side or in series in the direction of the longitudinal axis. Thus, for example, relatively narrow linear luminaires of any length are obtained, the minimum width of which is essentially determined only by the width of the respective matrix LEDs. Such linear luminaires are particularly suitable for use in aircraft as vehicles and in the passenger cabin as interior. According to the invention, this results in a linear luminaire with matrix LEDs, in which several matrix LEDs are aligned in the longitudinal direction on a printed circuit board.
    In an alternative embodiment, the luminaire is a spot or a reading lamp in which one or more matrix LEDs are installed.
    In an alternative embodiment, the luminaire is a planar luminaire which contains at least three light sources, at least three of the light sources being arranged side by side and distributed in two dimensions or distributed over a surface. The light sources are therefore distributed in a plane or on a surface, but not all of them juxtaposed in a linear fashion. For example, three light sources are distributed in the form of a triangle. With more light sources, these are for example distributed in rows and columns in two dimensions. This produces, for example, relatively large area luminaires with high light emission power, such as effect projectors, or also small, high intensity luminaires such as spotlights, reading or table lamps. Such luminaires are also particularly suitable for use in aircraft passenger cabins. According to the invention, this therefore results in a plane luminaire in which several matrix LEDs are aligned in two directions on a printed circuit board.
    In a preferred embodiment, the luminaire has an overlap. The overlay has a potential passage area for light which can be generated by at least one of the matrix LEDs. The covering is at least partially transparent in this passage area. Each matrix LED has a potentially largest emitting area when all the LED pixels of the matrix LED are active, i.e. illuminate, as much as possible in their normal operation. The emission zone is "potential" because, in actual operation, all the LED pixels are not necessarily fully lit. The actual emission area of the matrix LED may therefore be smaller. The maximum potential emission area defines by its cutting surface with the overlap the maximum potential passage area of the LED matrix light. As the corresponding passage area is at least partially transparent, all the light potentially generated by the matrix LED can leave the luminaire. In particular, the luminaire is completely transparent throughout the passage area, so that all the light potentially generated by the matrix LED can leave the luminaire or pass through the covering. Such a luminaire makes it possible to use the full potential of the matrix LED since all the light that it can generate can leave the luminaire.
    In a preferred embodiment, the luminaire does not have, in the whole of the potential light emission zone of at least one of the matrix LEDs, any element modifying in a variable manner the light emitted by the matrix LED. Such a luminaire therefore does not have any modifiable beam shape, variation in brightness or color for the light of the matrix LED. The corresponding change in lighting conditions is only achieved by variable activation of the matrix LED. This results in particularly simple and economical luminaires, of which, however, characteristics of the light emitted (direction, brightness, color, distribution, beam shape) can be modified.
    In a preferred embodiment, the luminaire contains a configuration means. In the configuration means, it is possible to define a configuration for activating the LED pixels of at least one of the matrix LEDs. The configuration cannot be changed, especially during normal operation of the luminaire. The configuration once defined is - if necessary - only modifiable in a maintenance mode or during a maintenance operation. For this purpose, for example, opening the light cover, connecting a programming connector, operating a DIP switch, etc. are necessary. In normal practical operation, in particular during a regular flight with passengers on a passenger plane, the configuration is fixed and not variable. Reconfiguration is then not possible, complex, not in accordance with the intended use, at least unusual or possible only with auxiliary means. The definition of activation in the form of configuration takes place, for example, only during the manufacture of the luminaire, its mounting at the place of use or during a reconfiguration as part of a maintenance activity on the luminaire.
    This therefore results in a "static" adaptation of the luminaire, in particular only once or during a maintenance activity. This adaptation is used in particular to calibrate the lighting characteristic of the luminaire. The calibration data is then stored in the configuration means. This allows, for example, to compensate for differences between luminaires of the same type that result from manufacturing tolerances. In addition, this eases the currently very strict (and therefore expensive) requirements on the manufacturing tolerances of luminaire components, since a corresponding calibration can even be carried out after manufacture. The calibration concerns for example the brightness, the light distribution and the color of the light generated by the matrix LED. Static adaptation can also be used to mechanically adapt identical types of luminaires to different installation situations in which a similar but not identical lighting characteristic is required. The configuration data are then stored in the configuration means. For example, the beam angle, shape or beam size can be changed. In this way, the diversity of mechanical design can be reduced and new lighting requirements fulfilled with existing luminaires.
    In a preferred embodiment, the luminaire has a control input by which, in normal operation, at least one of the LED pixels of one of the matrix LEDs can be activated (variably, individually and independently of the other LED pixels). Unlike the static adaptation described above, such a luminaire allows dynamic adjustment during normal operation, that is to say during operation at the end customer. Such an adaptation by activation at the control input can, for example, be used in programmed or programmable lighting scenarios in the aircraft cabin, for example to use a different lighting distribution during the boarding only during certain flight phases (takeoff, landing, meal, sleep, etc.). For example, when boarding, many passengers stand upright, so that a light distribution is controlled that minimizes the glare of standing passengers. Thanks to the control input, control of the luminaire according to a transmitter is also possible. The light behavior of the matrix LED therefore changes in response to the data acquired by the transmitter, for example a switch or a sensor, for example the environmental conditions (presence of people, ambient light, temperature, position of a rotary button) . For example, dimming, i.e. reducing the brightness, occurs when people pass through the light cone of the matrix LED, or targeted lighting occurs only in the currently used areas of a flashlight. reading, etc.
    In a preferred embodiment, the luminaire is a luminaire for an interior in the form of a passenger cabin and / or for a vehicle in the form of an airplane.
    The luminaire according to the invention is particularly suitable for use in passenger cabins or aircraft. The invention also relates to the use of a matrix LED as the light source of a luminaire as described below.
    The object of the invention is also achieved by the use of a matrix LED as the light source of a luminaire according to the invention, as described above. The use and at least part of its embodiments as well as the respective advantages have already been explained by analogy in relation to the luminaire according to the invention.
    The object of the invention is also achieved by a lighting module which comprises at least one luminaire, at least one of the luminaires being a luminaire according to the invention with the control input as described above. The lighting module contains a transmitter connected to the control input and a control and evaluation unit. This enables at least one of the matrix LEDs to be activated by the control input depending on the transmitter, or of a transmitter signal present at the transmitter. The transmitter is for example a sensor or an input unit or a control element for the user. The control and evaluation unit can be located inside or outside the luminaire. The transmitter signal is a signal that varies depending on the detection state of the transmitter. A lighting module is thus obtained which can generally react by a modified emission of light to correspondingly modified transmitter signals and which is therefore designed to be adaptive with respect to the transmitter. Such a lighting module is particularly flexible to use.
    The method and at least part of its embodiments as well as the respective advantages have already been explained by analogy in relation to the luminaire according to the invention.
    In a preferred embodiment, the transmitter is a control element. Thus, a deliberate or targeted activation of the lighting module or the luminaire with the matrix LED is possible. For example, the transmitter is part of an aircraft lighting control unit, which in normal operation is used by cabin crew to, for example, adjust various lighting scenarios on the aircraft. Such a lighting control unit is also called an "Attendant Control Panel" (ACP).
    In particular, the transmitter is a control element which can be actuated or operated by a user of the luminaire in the form of a passenger. In particular, the transmitter allows you to change, for example, the beam shape or the beam direction of the luminaire. The transmitter is then placed, for example, in the direct action zone of the luminaire or of an interior passenger who uses the luminaire; for an individual luminaire in an interior, for example at a seat or in an interior area associated with the luminaire. The luminaire is then, for example, a reading lamp, a toilet luminaire or a night light. The transmitter can therefore be an available transmitter at the passenger seat, by means of which the passenger can adjust the lighting individually for him.
    In a preferred embodiment, the transmitter is a sensor, in particular a presence sensor, a light sensor, a motion sensor or the like. The transmitter then detects an environmental condition, event, movement or other characteristics of objects or spaces to generate corresponding transmitter signals. The light emission characteristic of the matrix LED or of the luminaire is then modified adaptively according to the signal from the transmitter via the control and evaluation unit. It is thus possible to produce adaptive luminaires or lighting modules. The invention is based on the following findings, observations or considerations and further presents the following embodiments. The embodiments are sometimes also simply called "the invention". The embodiments may also contain parts or combinations of the embodiments mentioned above or correspond to them and / or, where appropriate, also include embodiments not mentioned above. The invention is based on the idea of producing luminaires for interior lighting, in particular aircraft cabin lighting, having a defined emission behavior. To this end, certain requirements relating to the lighting characteristic must be fulfilled as required. By "lighting characteristic" is meant here the spatial distribution of the light emitted on the one hand in terms of brightness (intensity) and on the other hand in terms of light color. The invention is based on the observation that the linear luminaires existing hitherto in aircraft cabins are produced by linear juxtaposition of groups of different discrete LED components on a printed circuit board in the longitudinal direction. The juxtaposition of several LEDs in the transverse direction is not possible or only very limited for reasons of space. For example, four or five LEDs can be arranged in the transverse direction, but not, for example, ten or more. An adaptation of the lighting characteristics of finished luminaires by an appropriate activation of the LEDs is therefore only possible in the longitudinal direction. Existing spots or reading lamps can be adapted, if necessary, in their emission characteristics by mechanical adjustment of the optical elements. Luminaires which are designed for different light distributions (emission characteristics) must always be equipped with different beam-forming optics (lenses or the like), since the characteristic of the source (discrete individual LEDs) is not variable. Once manufactured, the luminaires are no longer variable or calibrated with regard to their emission behavior.
    Thanks to the invention, for example, ceiling lighting for different ceiling configurations, in particular by means of embodiments in the form of linear luminaires, is possible. The aircraft manufacturer often offers airlines different ceiling configurations in the aircraft cabin. For example, in two-aisle planes, there are variants with and without luggage compartments above the middle seats. The lighting requirement for a luminaire that lights the ceiling towards the middle from the edge of the cabin depends on the presence of a ceiling configuration with or without luggage compartments in the middle. If luggage compartments are installed, the corresponding front side of the compartments must be lit. If none is installed, with the same light distribution, passenger glare in the opposite side row of seats would be possible, which should be avoided.
    Instead of a mechanically adapted luminaire, the invention described makes it possible, for this situation, to dim the corresponding pixels of the matrix LEDs which would generate unwanted light and to avoid glare. Therefore, the same fixture can be used in both situations and there is no need to develop an additional fixture variant. The adaptation is carried out statically during production or during the fitting of the luminaire.
    Thanks to the invention, table lighting is possible with the spot or reading lamp embodiments. In small private planes, the customer can compose the interior layout of the cabin as desired. For example, he can choose a round table or a square table. Both tables must be lit by a spotlight so that the table top is lit, but that no light goes beyond the table and reaches the ground. An appropriate activation of the matrix LED in the spot allows to precisely reach the contours of the table, without having to develop a specific luminaire for each table geometry. If the table also has a folding extension, the light cone could, in a controlled manner by a sensor, be dynamically enlarged to the extended table area (when the table is unfolded).
    Thanks to the invention, reading lamps are also possible in the embodiment as a flat luminaire. Reading lights are usually installed in the ceiling above the passenger seats. If there are three seats side by side in economy class, there may be only two seats in business class, for example. Thus, a solution would have to be found once with three and once with two individually usable reading lamps installed in the ceiling. A change in the number of seats then implies a corresponding adaptation of the reading lamps. With the solution according to the invention described, the reading lamps can be produced by a single matrix LED lighting module, for example in the embodiment as a flat luminaire. Depending on the occupancy or the seating equipment of the aircraft, the module is configured to allow the individual activation of three or two zones with the appropriate light distribution. Other characteristics, effects and advantages of the invention result from the description below of a preferred embodiment of the invention and from the appended figures. These show in a schematic representation of principle: figure 1: a spot / reading lamp, figure 2: a linear luminaire, figure 3: a flat luminaire, figure 4: a luminaire with overlap and different beam configurations, figure 5: a passenger cabin in two variants with a luminaire configured differently, Figure 6: a lighting module with two table variants.
    Figure 1 shows a light fixture 2 for an interior 4, not shown in detail in Figure 1, of a vehicle 6 in top view. The luminaire 2 contains a basic body 8 by means of which the luminaire 2 is fixed in the interior 4 or to the vehicle 6. The luminaire 2 also contains a light source 10 in the form of a matrix LED 12 which is fixed to the base body 8. In the example, the matrix LED 12 has 8 × 8, that is to say 64 pixel LEDs 14. The matrix LED 12 is mounted on a printed circuit board 16. The luminaire 2 is a spot or a reading lamp.
    Figure 2 shows a detail of another luminaire 2 in the form of a linear luminaire 18 which extends along a longitudinal axis 20. The basic body 8 is omitted for the sake of clarity. In the example, the linear luminaire contains several light sources 10, three of which are shown. All of the light sources 10 are arranged side by side or in series along or along the longitudinal axis 20.
    FIG. 3 shows another luminaire 2 in the form of a plane luminaire 22. The basic body 8 has been omitted for the sake of clarity. In the example, the planar luminaire 22 contains nine light sources 10 in the form of matrix LEDs 12 which are arranged one next to the other and distributed in two dimensions, namely here in lines 24a and columns 24b.
    FIG. 4 shows another luminaire 2 with a basic body 8 and a light source 10 in the form of a matrix LED 12 in a side view. The luminaire 2 also has an overlay 26. The matrix LED 12 generates at full speed, that is to say when all the LED pixels 14 emit light in accordance with their destination, a light cone or an area of broadcast 28 of maximum size. The intersection of the maximum emission zone 28 with the covering 26 forms a maximum potential passage area 30 of the light which is generated by the matrix LED 12 and meets the covering 26. Throughout the passage area 30, the covering is at least partially transparent, here completely transparent.
    Although the covering 26 forms a beam-forming element in the passage area 30, in this case a lens in the beam path or the area for emitting the light of the matrix LED 12, the setting beam shape cannot be changed, but fixed.
    The luminaire 2 contains a configuration means 32, in the example a memory chip whose configuration or programming can be modified for example during the maintenance operations on the luminaire 2, but not during the normal operation of the luminaire 2. The configuration defines which LED pixels 14 of the matrix LED 12 are activated and how. Depending on the configuration, different beam profiles or light cones 29a-c are obtained, the light cone 29a generating in a first configuration (activation of all LED pixels 14) the largest beam profile, which corresponds to the area d emission 28. The light cone 29b is generated using a second configuration and forms a narrower beam profile but centered with respect to a central optical axis 34, the light cone 29c according to a third configuration is a asymmetrical beam profile with respect to the central optical axis 34. In the example, the matrix LED 12 is an LED which makes it possible to generate colored light. By configuration, the light cone 29a is a light cone for white light, the light cone 29b a light cone for blue light and the light cone 29c a light cone for purple light (mixture of the R components and B LED pixels R and B 14). The color of the light emitted by the luminaire 2 is therefore configured accordingly in the configuration means 32.
    FIG. 5 symbolically represents another example of two different configurations of a luminaire 2 by a configuration means 32. Part of the interior 4, here a passenger cabin, of the vehicle 6, here an airplane, is shown there, namely, a ceiling area 36 as well as a row of left seats 38a, central 38b and right 38c. The ceiling area 36 has, in a first variant or variant arrangement of the aircraft 6, central luggage compartments 40 above the row of seats 38b. In a first configuration, the luminaire 2 generates light with the light cone 29a to illuminate the side wall of the luggage compartments 40.
    The manufacturer of the aircraft 6 can also deliver it in a different configuration, namely without the luggage compartments 40 but with another part of the ceiling 42. If the luminaire 2 then also works in the configuration with a light cone 29a, the passengers in the right seat row 38c can be dazzled by the luminaire 2, as indicated by a dashed line. Consequently, using the same luminaire 2, it is simply reconfigured during the manufacture of the aircraft 6 as regards its configuration means 32, so that it works with the light cone 29b. Now only structural element 42 is still lit. A glare effect in the row of seats 38c is now avoided.
    FIG. 6 symbolically shows, for another aircraft as vehicle 6, a luminaire 2 which has a control input 44 by which, in normal operation, at least one of the LED pixels 14, here all of the matrix LED 12 can be activated. The luminaire 2 is part of a lighting module 46 which, in addition to the luminaire 2 with the control input 44, also contains a transmitter 48. The transmitter 48 is here a sensor can be used to detect a folding position of the folding table 50. The transmitter is connected to the control input 44 by means of a control and evaluation unit 49.
    When the folding table 50 is in a folded position, it has the surface of a square table top 52 which must be lit by the luminaire 2. The folded position is detected by the transmitter 48 and the luminaire 2 is activated with a cone of light 29a which exactly illuminates the square table top 52. When the folding table 50 is unfolded and the table top 52 extended in a rectangle by an additional element 54, this is also detected by the transmitter 48. The control input 44 is then activated by the control and evaluation unit 49 so that the cone of light 29b which results in exactly rectangular illumination of the table top 52 with the additional element 54.
    The manufacturer can also deliver the aircraft or vehicle 6 in another configuration with a round table 56. The same luminaire 2 is installed in this aircraft too. The control and evaluation unit 49, however, now activates the luminaire 2 so that a round cone of light 29c results which exactly illuminates the round table 56. The transmitter 48 is here a maneuverable input means by a user of the round table 56 to change the color and the brightness of the light generated by the luminaire 2 as desired.
    The following objects, parts, components or elements are illustrated and referenced in the appended figures: 2: luminaire 4: interior 6: vehicle 8: base body 10: light source 12: matrix LED
