Abstract

Beschrieben wird eine neue Leuchtstoffmischung für eine Spezialleuchtstofflampe zur Beleuchtung von Lebensmitteln, insbesondere Fleisch- und Wurstwaren. Durch eine Mischung von Halophosphatleuchtstoffen mit einem Rotleuchtstoff mit einem Emissionsmaximum nahe 625 nm und durch optionale Zugabe eines schmalbandigen Grünleuchtstoffs lassen sich gute Schönungswirkungen und unterschiedliche spezielle Farbwiedergabeindizes in einem breiten Bereich einstellen.

A new fluorescent mixture is described for a special fluorescent lamp for illuminating foods, in particular meat and sausage products. A mixture of halophosphate phosphors with a red phosphor with an emission maximum near 625 nm and the optional addition of a narrow-band green phosphor can be used to achieve good fining effects and different special color rendering indices in a wide range.
