Abstract: A light-emitting composite arrangement for stationary arrangement in an interior of an aircraft is provided. The light-emitting composite arrangement has a base layer, a covering layer and a core portion at least partially provided between the base layer and the covering layer. The covering layer can be a prepreg layer. A lighting device is integrated in the core portion. The covering layer is cured with the lighting device integrated in the core portion.

Abstract: A light-emitting composite arrangement 1 for stationary arrangement in an interior of an aircraft is proposed, comprising a base layer and a covering layer 2, 3, wherein the covering layer 3 is a prepreg layer, comprising a core portion 4, which is arranged, at least in some areas, between the base layer and the covering layer 2, 3, comprising at least one lighting device 5, which is integrated in the core portion 4, wherein the covering layer 3 is cured with the lighting device 5 ntegrated in the core portion 4.

Abstract: A method for avoiding physiological phenomena such as color separation or stroboscopic effects that occur under boundary conditions in the case of intermittent feeding in particular of light-emitting diodes, for additive superposition to form color-locus-variable mixed light, whereby the emission brightness that can be represented by a periodic duty ratio of a pulse-time-modulated constant current feeding—preferably within the respective period—is realized by changeover to other or between different constant current intensities in such a way that a brightness equivalent, namely once again the current-time integral of the predetermined, brightness-determining duty ratio, arises in the current area sum, which now preferably no longer exhibits gaps over the period.

Abstract: In order to avoid firstly decidedly periodic loading of an output-buffered constant current power supply unit (17) and secondly physiological loading as a result of only intermittently appearing primary colors (R, G, B) when activating mixed light color loci, primary color light sources (11R, 11G, 11B) are energized in pulse-width-modulated fashion periodically in a temporally offset manner, but in addition in each instance, in time-parallel fashion with respect thereto, also those primary color light sources of further primary color light sources (11R, 11G, 11B) whose primary colors in the cyclic activation are not being energized at that time are likewise energized in a pulse-width-modulated manner (FIG. 2).
