ABSTRACT:
A method of making a light emitting device includes mixing a glass powder with a phosphor powder including at least one of a sulfide phosphor, an aluminate phosphor and a silicate phosphor to produce a mixed powder in which the phosphor powder is dispersed in the glass powder, heating and softening the mixed powder to provide an integrated material, and subsequently solidifying the integrated material to provide a phosphor-dispersed glass, and fusion-bonding the phosphor-dispersed glass onto a mounting portion on which a light emitting element is mounted by hot pressing, and simultaneously sealing the light emitting element with the phosphor-dispersed glass on the mounting portion.
