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 P2O5, from 0.1 to 20 mol % of ZnO, from 0 to 10 mol % of SiO2+GeO2, from 0 to 30% of Li2O+Na2O+K2O, 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 400 nm.
