GLASS COATED LIGHT EMITTING ELEMENT AND GLASS COATED LIGHT EMITTING DEVICE

摘要

This invention provides a glass coated light emitting element, which contains foams with a size of not less than 1 µm in an amount small enough to lower the transmittance by visible light scattering and is coated by a glass film with a total light transmittance of 85% or higher, and a glass coated light emitting device using the glass coated light emitting element. The glass coated light emitting element is coated with glass. The glass has been produced by firing a glass frit and has a softening temperature of 600ºC or below, a total light transmittance of not less than 85%, and an expansion coefficient of 70 x 10-7 to 125 x 10-7/ºC. The content of foams having a diameter of not less than 1 µm is not more than 500000 foams/mm3.
