摘要：
A light emitting device and a method for manufacturing a light emitting device, wherein the light emitting device comprises a light emitting diode (LED) emitting light in a first emission spectrum, and a composition comprising at least two components and being adapted to absorb at least a part of the light in the first emission spectrum and upon absorption to emit an up-converted light in a second emission spectrum, wherein the light in said second emission spectrum has a wavelength range lower than the wavelength range of the light in the first emission spectrum, whereby the light emitted by the light emitting device comprises a mixture at least of light in the first emission spectrum and of light in the second emission spectrum.
