Abstract:
1. A light source apparatus, comprising: a semiconductor light emitting device including a light emitting unit, a first conductive member, a second conductive member, a sealing member, and an optical layer; a mounting substrate including a base body, a first substrate electrode, and a second substrate electrode, the first substrate electrode and the second substrate electrode being provided on a surface of the base body to oppose the semiconductor light emitting device; a first connection member configured to electrically connect the first conductive member to the first substrate electrode; and a second connection member configured to electrically connect the second conductive member to the second substrate electrode, the light emitting unit including: the first conductive member being electrically connected to the first light emitting unit electrode and including a first columnar portion provided on the second major surface, the second conductive member being electrically connected to the second light emitting unit electrode and including a second columnar portion provided on the second major surface, the sealing member covering a side surface of the first conductive member and a side surface of the second conductive member, the optical layer being provided on the first major surface of the semiconductor stacked body, the optical layer including a wavelength conversion unit, the wavelength conversion unit being configured to absorb an emitted light emitted from the light emitting layer and emit a light having a wavelength different from a wavelength of the emitted light, a surface area of the second substrate electrode being not less than 100 times a cross-sectional area of the second columnar portion cut by a plane parallel to the second major surface.
