LIGHT-EMITTING COMPONENT PROVIDED WITH A LUMINESCENCE CONVERSION ELEMENT

摘要

The device has at least one primary radiation source that emits primary electromagnetic radiation and at least one luminescence conversion element (5) with which at least part of the primary radiation is converted into radiation of a different wavelength. A filter element (1) with a number of nano-particles (2) is arranged after the luminescent conversion element in the radiation emission direction. The nano-particles have a filter substance that selectively reduces the radiation intensity of at least one spectral sub-region of unwanted radiation by absorption.
