    摘要： A light-emitting device has a light-emitting element including first and a second semiconductor light-emitting structures, each having a first and a second electrode, and a substrate supporting the light-emitting element. The substrate has an interconnection layer having a first interconnection portion comprising a first land, a second interconnection portion comprising second and third lands, and a third interconnection portion comprising a fourth land, and a first reflective member covering a portion of the interconnection layer. A portion of the first land is coupled to the first electrode of the first semiconductor light-emitting structure. A portion of the second land and a portion of the third land are coupled to the second electrode of the first semiconductor light-emitting structure and the first electrode of the second semiconductor light-emitting structure, respectively. A portion of the fourth land is coupled to the second electrode of the second semiconductor light-emitting structure.

    摘要： A light emitting device includes a substrate, a light source, a cover member, a light transmissive member disposed on or above the light source, a light reflecting layer disposed on or above the light transmissive member, and a light transmissive cover member. The cover member is made of a resin material containing a light reflecting substance and covers a lateral face of the light source. The light transmissive cover member covers at least a lateral face of the light transmissive member and includes an annular lens part. A thickness of a portion of the light transmissive cover member disposed above a perimeter of the light reflecting layer is larger than a thickness of a portion of the light transmissive cover member disposed above a portion of the light reflecting layer where an optical axis of the light emitting element passes through.
