摘要： A light emitting component comprising a first LED light source for emitting blue light, a second LED light source for emitting red light, and a luminescent layer (100) comprising a solid polymer composition and green luminescent crystals. The solid polymer composition comprises a polymer. The green luminescent crystals are perovskite crystals. The first and the second light source are directed to the luminescent layer. Upon absorption of the light emitted by the first light source, the lumi-nescent crystals emit light of a wavelength in the green light spectrum.
