A wavelength conversion member 102 including a solid state light source 101 adapted to emit primary light L1 and a plurality of wavelength conversion domains 102a, 102b, 102c, etc. for converting the primary light into secondary light L2, The wavelength conversion domain includes a wavelength conversion member thereby providing a sub-range of the total light output spectrum, wherein at least a portion of the wavelength conversion domain is arranged as an array, includes quantum dots, and different wavelength conversion domains are all light Comprising quantum dots with different secondary light emission ranges providing different subranges of the output spectrum, wherein the subrange provided by each wavelength conversion domain overlaps at least one other subrange provided by another wavelength conversion domain, or A continuous light emitting device is provided. By arranging materials having different wavelength conversion characteristics in different domains, preferably in one plane, reabsorption of secondary light emission can be avoided. |
