Abstract:
1. A method for producing 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 glass substrate, the chip being seated on 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 conversion element is contained in the vitreous body, the refractive index of the vitreous body is higher than 1.6, said method comprising: sintering a mixture of phosphor and glass powder to a temperature in the vicinity of the softening point of the glass such that the phosphor penetrates the glass substrate only from one side; forming the vitreous body based on the group consisting of crown glass, flint glass, bismuth containing borate glass, phosphate glass, and a glass whose main component is Al wherein the glass substrate is formed by the vitreous body.
