Method of producing a wavelength-converting casting composition

摘要

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 phosphororous group of the general formula A3B5X12:M, and the luminous substance pigments have particle sizes <=20 mum and a mean grain diameter d50<=5 mum.
