Abstract:
1. A semiconductor light emitting apparatus comprising: a heat dissipation member to dissipate heat generated by a heat generating element, the heat dissipation member being formed of a first plate-shaped member and a second plate-shaped member that form a flow path for flowing cooling fluid between them; and a plurality of light emitting elements that are mounted to be two-dimensionally arranged on a main surface of the heat dissipation member, wherein said heat dissipation member defines an inlet for an intake of the cooling fluid and an outlet communicating with the inlet for an ejection of the cooling fluid, wherein a plurality of protruding portions are formed on a surface of said first plate-shaped member inside said flow path, and wherein said second plate-shaped member defines a fan-shaped recessed section that extends from said inlet and/or said outlet toward a center part of said second plate-shaped member substantially in a fan shape on a surface of said second plate-shaped member inside said flow path.
