Abstract:
A light emitting device includes a light source including an inorganic material substrate, a light emitting element mounted on a mounting surface of the inorganic material substrate, and a metalized pattern formed on a non-mounting surface of the inorganic material substrate on which the light emitting element is not mounted, a mounting substrate including an mounting surface on which the light source is mounted, and a conductor pattern formed on the mounting surface and bonded to the metalized pattern, and an optical member disposed on the mounting surface of the mounting substrate so as to guide a light emitted from the light source in a predetermined direction. The optical member includes a heat absorbing surface at least a part of which faces the conductor pattern of the mounting substrate, and a heat radiating surface that radiates heat of the light source conducted from the conductor pattern via the heat absorbing surface.
Abstract:
A light emitting device has a light emitting element, a mounting portion and a sealing part. On the mounting portion, the light emitting element is mounted and a circuit pattern is formed to supply power to the light emitting element. The sealing part is formed on the mounting portion, sealing the light emitting element, and formed of a glass and a phosphor uniformly dispersed in the glass. The phosphor is adapted to emit a wavelength-converted light by being excited by a light emitted from the light emitting element.
