LIGHT SOURCE WITH ADAPTED SPECTRAL DISTRIBUTION Russian patent published in 2018 - IPC A61B5/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment. White light spotlight for luminescence, for example a biomarker, 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 wavelength converting 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 said converting materials is controllable to form said spectrum.

EFFECT: object of the present invention to overcome this problem, and to provide a light source, in particular a spotlight, having an emission spectrum that is adapted to facilitate detection of a fluorescent molecule.
