Abstract: 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 as 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. Said compound is most preferably {Na3}[Al2-x-yMnxMgy](Li3)F12-dOd.
