Abstract:
An advisory lighting fitting with a luminous body which has at least one light-radiating light outlet surface, which is divided up into part surfaces radiating in various colors, and with a light source arrangement radiating light into the luminous body, the luminous body having a light conduction plate arrangement with limiting walls, wherein the luminous body is composed of light conducting plates, each of which are arranged at least one of above, adjacent to and in each other, the plates having various part surfaces, and that various light sources are assigned to the light conducting plates, corresponding to the part surfaces radiating in various colors, which light sources radiate variously colored light into the respective light conducting plates, and a filter is arranged in front of at least one corresponding part surface of the light outlet surface, the filter having a spectral transmission curve which has a maximum in the wavelength range of the light radiated by the corresponding light source and, moreover, demonstrates such reflection and absorption behavior that the radiated light has a color range which remains intact when subjected to an external light radiation by means of white light.
