摘要:
A light-emitting device includes a light-emitting element, a wavelength conversion member arranged on the light-emitting element, a light-reflective member and a light-distributing member. The light-reflective member covers lateral surfaces of the light-emitting element and the wavelength conversion member while an upper surface of the wavelength conversion member being exposed from the light-reflective member. The light-distributing member has a plate shape with an upper surface and a lower surface. An inner wall of the light-distributing member defines a through-hole disposed above the wavelength conversion member and extending between the upper surface and the lower surface. The inner wall is inclined from an upper edge of the through-hole defined by the upper surface toward a lower edge of the through-hole defined by the lower surface so that an opening defined by the lower edge is larger than an opening defined by the upper edge.
