摘要： A light emitting device includes a package including a recess which includes a bottom surface having a substantially circular shape with a circular center, and light emitting elements provided on the bottom surface. Each of the light emitting elements has a substantially regular hexagonal shape. The light emitting elements include a first light emitting element, second light emitting elements provided to surround the first light emitting element, and a light reflective resin disposed between the first light emitting element and the second light emitting elements. The first light emitting element has an element center of the substantially regular hexagonal shape and is disposed on the bottom surface so that the element center substantially coincides with the circular center. Each side of the substantially regular hexagonal shape of the first light emitting element opposes one side of each of the substantially regular hexagonal shapes of the second light emitting elements.

摘要： A light emitting device includes: a light emitting element; a first reflecting member containing reflecting particles, and covering the upper surface of a base while exposing a light extraction surface of the light emitting element; a first cover member having a lower concentration of reflecting particles than the first reflecting member and covering the first reflecting member and a portion of lateral surfaces of the light emitting element while exposing the light extraction surface of the light emitting element; a second cover member covering a portion of the lateral surfaces of the light emitting element; a second reflecting member surrounding the second cover member in a top view and contacting the second cover member and the first reflecting member; the second reflecting member having a narrow-width portion being in contact with the first reflecting member and a wide-width portion located above the narrow-width portion in a cross-sectional view.
