ABSTRACT:
The wavelength-converting casting composition is based on a transparent epoxy casting resin with a luminous substance admixed. The composition is used in an electroluminescent component having a body that emits ultraviolet, blue or green light. An inorganic luminous substance pigment powder with luminous substance pigments is dispersed in the transparent epoxy casting resin. The luminous substance is a phosphorous group of the general formula A.sub.3 B.sub.5 X.sub.12 :M, and the luminous substance pigments have particle sizes<20 .mu.m and a mean grain diameter d.sub.50 <5 .mu.m.
