  • Luminescence conversion LED
    Patent number: 8690629
    Abstract: A luminescence conversion LED having a radiation emitting chip that is connected to electrical connections and is surrounded by a housing that comprises at least a basic body and a cap, the chip being seated on the basic body, in particular in a cutout of the basic body, and the primary radiation of the chip being converted at least partially into longer wave radiation by a conversion element, wherein the cap is formed by a vitreous body, the conversion means being contained in the vitreous body, the refractive index of the vitreous body being higher than 1.6, preferably at least n=1.7.
