    摘要： The invention provides a light emitting diode device comprising a light emitting diode arranged on a substrate and a wavelength converting element. The wavelength converting element contains a luminescent material a Mn4+-activated fluoride compound having a garnet-type crystal structure. The Mn4+-activated fluoride compound preferably answers the general formula {A3}[B2-x-yMnxMgy](Li3)F12-dOd, in which formula A stands for at least one element selected from the series consisting of Na+ and K+ and B stands for at least one element selected from the series consisting of Al3+, B3+, Sc3+, Fe3+, Cr3+, Ti4+ and In3+, and in which formula x ranges between 0.02 and 0.2, y ranges between 0.0 (and incl. 0.0) and 0.4 and d ranges between 0 (and incl. 0) and 1. As the luminescent materials of the described type and structure have high stability and low sensitivity towards humid environments, they can advantageously be used as in wavelength conversion elements of LED devices.

    摘要： The invention relates to a lighting (1) device comprising a light source (2) and a wavelength converting element (7), which comprises a phosphor compounded with a polymer. The phosphor contains a metal-ion activator which is excitable via a partially forbidden electronic transition. The phosphor and the polymer being chosen such that the difference in their refractive index is smaller than 0.1. Due to this choice, scattering in the wavelength converting element (7) remains at minimum. Interesting wavelength converting elements (7) are obtained when using phosphors comprising specific Mn(IV)-activated fluoride compounds and specific fluorine-containing polymers.
