Me widening of the line spectrum of the radiation from a Qasentladungslichtguelle and thus its color change with the help of τοη light st open is known. In this application, the task of the phosphor is to improve the light output of a light source. This is because the invisible short-wave radiation of this light source is converted into visible light. The formation of entire reflectors or the Austrian τοη reflector parts with luminescent materials to avoid the corneal fluorescence known as the fog effect "is known. is generally produced in lighting technology by filtering incandescent lamp or gas light or the light of a gas discharge with the help of colored glasses. B. blue light, which is generated by Slühlasipen, with the use of all known Slltex also red and green standard radiation.

It serves the same purpose of achieving uniform floor lighting The shaping of the fluorescent wide beam lamp in such a way that the light The distribution curve of the luminaire with diffraction of short-wave light has a larger one Broad radiation possesses as "when generating long-wave light" when generating short-wave light, the illuminated surfaces must be against the horizontal stand steeper than in the other case. Furthermore, the colored light is generated by large luminous areas with low luminance. Large illuminated areas achieve a more even floor lighting than the lights with the usual point-like effect according to the G-eseta of the photoraetriacimnSrenaentfernaag. Seflektxorea. SrpSflächertleuchten are also anti-glare, since direct glare from invisible arrangement of Jairegelichtq.uelle _f indirect glare caused by the distribution of the luminous flux on a large Fläclie is avoided. The generation of high luminance levels on luminescent materials requires intensive excitation, which reduces the life of all known luminescent materials. The use of phosphors on large pools of leucorrhea for the purpose of There is also a high level of equilibrium lighting in such a way that that, by JLaderaog, the concentration of the fluorescent substance on each plane and part the luminous area in Abho.ngxgfceit from the distance of each ITäehentails to the radiation source the same luminance is produced and therewith the luminance differences be balancedea that are based on non-luminescent radiation «- areas are inevitable. The change in concentration of the phosphor brings it comes with the fact that compared to the well-known large-area lights of a Strahliza so-called uelle larger illuminated areas with completely uniform luminance can be. With regard to easy maintenance and cleaning, the illuminated areas in the luminaire can be arranged interchangeably.
