Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Further features, effects and advantages of the invention become apparent from the following description of one preferred exemplary embodiment of the invention and the appended figures. In the figures, in each case in a schematic diagram:

[0041] FIG. 1 shows a passenger cabin of an aircraft having a display surface and luminaires in a perspective illustration,

[0042] FIG. 2 shows a lighting arrangement according to the invention in a basic overview,

[0043] FIG. 3 shows part of an alternative lighting arrangement according to the invention in a basic overview.

DETAILED DESCRIPTION OF THE INVENTION

[0044] FIG. 1 shows a cutout of a passenger cabin 2 of an aircraft, not shown in more detail, namely essentially its ceiling region with ceiling panels 4 and luggage compartments 6. Luminaires 8 (here strip luminaires) in the form of cabin lighting or ceiling lighting are in each case arranged between the panels 4 and the luggage compartments 6 (indirectly, therefore not directly visible in FIG. 1). Some of the panels 4 in this case form a display surface 10 on which image content 12, here a panoramic image of a cloudy sky, is currently being displayed.

[0045] The display surface 10 in this case has three surface portions 14a-c, which each depict a content portion 16a-c of the image content 12. Each of the content portions 16a-c is generated by one of three projectors, not visible in FIG. 1. The surface portions 14a-c are thus respective sections of the surface of the passenger cabin 2 (of the panels 4) that are illuminated by in each case one of the projectors in order to display the respective content portion 16a-c.

[0046] The luminaires 8 are positioned in a lighting environment 18 of the display surface 10. The lighting environment 18 is in this case that region at a maximum distance of 30 cm from the display surface 10 and indicated by a dashed line.

[0047] The luminaires 8 are part of a lighting arrangement 20 and emit light 22 (indicated symbolically here only by an arrow) during active operation.

[0048] FIG. 2 symbolically shows the lighting arrangement 20 for the passenger cabin 2 from FIG. 1 in detail. The passenger cabin 2 has, as explained above, the display surface 10 with the surface portions 14a-c, on which the content portions 16a-c are depicted, which combine to form the image content 12. The lighting arrangement 20 additionally comprises a total of twenty-four luminaires 8 that are grouped into respective groups of four, wherein in each case three groups of four form one of the two strip luminaires indicated in FIG. 1. The luminaires 8 are all situated in the lighting environment 18 of the display surface 10. Each of the luminaires 8 in each case radiates light 22 (again depicted symbolically here by an arrow) during active operation. The light 22 in this case has lighting parameters 24, here a particular brightness H and a colour in the form of a colour coordinate F.

[0049] The lighting arrangement 20 additionally contains a control unit 26. In the control unit 26, each of the luminaires 8 is assigned part of the display surface 10 as evaluation region 28. The assignment is indicated symbolically as a double-headed arrow in FIG. 2. In the control unit 26, each of the luminaires 8 is additionally assigned a mapping rule 30. The mapping rule 30 assigns image content 12 (the portion thereof) in the respective evaluation region 28 of the respective luminaire 8 a value of the respective lighting parameters 24 for the respective luminaire 8. In the example, a value for the brightness H and a value for the colour coordinate F is therefore assigned to each individual luminaire 8. For the sake of clarity, this is illustrated explicitly for just a single luminaire.

[0050] The control unit 26 performs the corresponding assignment, and thus determines, in the example, for each luminaire 8, its values for the brightness H and the colour coordinate F, and actuates the respective luminaire 8 with the corresponding values in terms of brightness H and colour coordinate F.

[0051] The assignment between luminaire 8 and evaluation region 28 is able to be defined freely in this case. The evaluation regions 28 are able to be defined freely in terms of number, aspect ratio, size and position. The evaluation algorithm (mapping rule 30) is able to be defined freely. In the example, the centre point of the colour coordinate in the evaluation region 28 is determined as value of the colour coordinate F. The average brightness in the evaluation region 28 is determined as value for the brightness H. The arrangement of the lighting elements (both of the display surface 10 and of the luminaires 8) is independent of the arrangement of the projected images, since an assignment takes place. The lighting parameters 24 may selectively be determined in real time or through calculation in advance. The lighting arrangement 20 is able to be scaled with respect to the projection surfaces, that is to say to the display surfaces 10, to the evaluation regions 28 and to the actuated luminaires 8.

[0052] The content portions 16a-c are generated in the example by in each case one light source 32, here a respective projector, per surface portion 14a-c. To determine or to receive the image content 12 (or the respective portions of the overall image content 12) within the evaluation regions 28, the control unit 26 has an interface 34 to the light sources 32.

[0053] The evaluation regions 28 (or their size, position, etc.), the mapping rules 30 for all of the luminaires 8 and the respective assignments of these elements to the luminaires 8 are stored in a configuration database 36 (indicated by a dashed frame) of the control unit 26.

[0054] FIG. 3 once again shows the lighting arrangement 20 from FIG. 2, the control unit 26 being omitted for the sake of simplicity. In this case, the surface portions 14a-c are configured in an alternative design as three surfaces of three screens as a respective light source 32. Applied to FIG. 1, three screens are thus recessed into the panels 4 as light sources 32, whose surfaces form the surface portions 14a-c. The content portions 16a-c are the image information depicted on the screens.

[0055] In this case, the lighting elements in the form of the groups of four luminaires 8 do not correspond to the surface portions 14a-c, as is the case in FIG. 2.

[0056] In FIG. 3, in addition to the twenty-four luminaires 8 of the lighting arrangement 20, which are thus arranged in alternative groups of four here, a further eight luminaires 8 are also provided, which thus form protruding lighting elements (illustrated by dashed frames). These may be controlled independently of the luminaires 8 of the lighting arrangement 20, and thus independently of the image content 12.
