- the present invention relates to a lighting arrangement comprising a plurality of light sources, each of which emits light in a different color. Furthermore, the present invention relates to a method for operating a corresponding illumination arrangement, wherein the differently colored light sources can be in particular LEDs.
- Workplace lighting is known to generate certain lighting moods by the use of colored light sources or to reproduce the temporal course of natural daylight artificially. For this purpose, for example, a bluish hue is added to the light during the day, whereas in the morning or evening, the light emitted is given a slightly reddish hue. It has been found that such lighting effects are perceived as pleasant and able to support the biorhythm of humans.
- Merchandiser facilities In shops, especially in grocery stores, white lighting with a high proportion of red or yellow light is often used to improve the presentation of goods of certain foods, especially fresh goods such as meat, sausage, fish, vegetables or cheese. If fresh goods are illuminated with light of a specific color temperature or a specific color location, they often look fresher and more natural or generally more appealing than would be the case with conventional lighting. Also in the presentation of other products, so not only at

- FIGS. 2a and 2b show examples of two different spectral compositions for a light emission at substantially the same color location
- FIG. 3 shows an example of a device used according to the invention
- FIG. 4 schematically shows a first example of application of the present invention
- Figure 5 is an example of a graphical user interface for setting the desired light output
- Figure 6 is a schematic representation of the time of day dependent
- FIG. 1 shows a so-called CIE color diagram in which the different colors of the color space are shown.
- the diagram is bounded on its outer circumference by the so-called spectral color line, which begins in the lower left corner at a wavelength of 380 nm, which corresponds to a light in the violet color range.
- Spectral color line then extends over the other wavelengths with the corresponding colors and ends in the lower right corner at about 780 nm, which corresponds to a red light output. Also marked is the so-called Planck 's Curve, which represents the area of the color space in which the light is perceived essentially as white light, but at different color temperatures. As is well known, the possibility exists through the combination
- the light output can be achieved in a different manner according to a particular color location or a color temperature or the light has a different spectral composition. This will be explained below with reference to Figures 2a and 2b.
- FIG. 3 shows a luminaire which is used to implement the idea of the invention described above. It is in the illustrated
