  • Wavelength converting element
    Patent number: 9897285
    Abstract: A wavelength converting element (101, 102, 103, 110) comprising a polymeric carrier material comprising a first wavelength converting material adapted to convert light of a first wavelength to light of a second wavelength, wherein the oxygen diffusion coefficient (D) of the polymeric carrier material is 8×10?13 cm2/s or less at 25° C. A prolonged lifetime of the wavelength converting material is achieved by selecting a polymeric carrier material with an oxygen diffusion coefficient (D) at 8×10?13 cm2/s or less at 25° C.
    Type: Grant
