LIGHT SOURCE WITH ADAPTED SPECTAL OUTPUT

摘要

The white light spotlight for luminescence (e.g. biomarker) detection according to the invention comprises: •at least one solid state light emitting element to emit primary light, and •a plurality of wavelength converting materials, to convert part of primary light into secondary light, provided as an array of independent wavelength converting domains, wherein different domains comprise converting materials producing different secondary light emission bands/peaks, each converting material being adapted to convert primary light into secondary light, wherein each converting material is adapted to contribute to the total emission spectrum with at least one emission band/peak and the total secondary light emission provided by said converting materials provides a broad band emission spectrum except for at least one defined narrow wavelength range in which the spotlight produces no or significantly reduced light emission, and wherein the combined light emission from the converting materials is controllable to form said spectrum.
