A light emitting arrangement is provided, comprising:—a solid state light source (101) adapted to emit primary light (L1); and—a wavelength converting member (102) comprising a plurality of wavelength converting domains (102a, 102b, 102c, etc) for converting primary light into secondary light (L2), each wavelength converting domain thereby providing a sub-range of the total light output spectrum, wherein at least some of said wavelength converting domains are arranged as an array and comprise quantum dots, wherein different wavelength converting domains comprise quantum dots having different secondary light emission ranges providing different sub-ranges of the total light output spectrum, and wherein a sub-range provided by each wavelength converting domain overlaps or is contiguous with at least one other sub-range provided by another wavelength converting domain. By arranging materials having different wavelength conversion properties in different domains, preferably in a plane, re-absorption of secondary emission can be avoided.
A light emitting arrangement (100) adapted to provide a total light output spectrum, comprising:
(canceled)
Use of a plurality of quantum dots having different secondary light emission ranges for providing a continuous total light output spectrum including all wavelengths of the range from 400 nm to 800 nm.
