Abstract
A light emitting diode element having a light emitting diode; and a glass covering sealing the light emitting diode is provided. The glass of the covering consists essentially of from 30 to 70 mol% of SnO, from 15 to 50 mol% of PO, from 0.1 to 20 mol% of ZnO, from 0 to 10 mol% of SiO+GeO, from 0 to 30% of LiO+NaO+KO, and from 0 to 20% of MgO+CaO+SrO+BaO. In an embodiment, a refractive index of the glass of the covering is at least 1.6 at a wavelength of 400nm.
