(57) [Summary]n[PROBLEMS] To show high invariance even when the operating temperature changes. It emits white light and has particularly high color reproduction and high efficiency. Providing lighting units thatnThe conversion uses at least one phosphor. The phosphor is cation M and silicon nitride or niobium. Derived from a derivative of torido, this phosphor is 430-6 Emits light at the peak emission wavelength at 70 nm. On is partly dopant D, ie Eu 2+ Or Ce 3+ In this case the cation M And at least one of the divalent metals Ba, Ca and Sr And / or at least of the trivalent metals Lu, La, Gd, Y One type is used and this phosphor is of the following type: structure MSi 3 N 5 , M 2 Si 4 N 7 , M 4 Si 6 N 11 And M 9 Si 11 N 23 Nitride, structure M 16 Si 15 O 6 N 32 Oxynitride of structure MSiAl 2 O 3 N 2 , M 13 Si 18 Al 12 O 18 N 36 , MSi 5 Al 2 ON 9 And M 3 Si 5 AlON 10 Derived from sialon Illumination unit having at least one LED as a light source knit. |
