Abstract:
A light emitting device includes: a base; a first semiconductor laser element disposed on an upper surface of the base and configured to emit first light; a first light reflecting member disposed on the upper surface of the base and configured to reflect the first light upwards; a phosphor member having a lower surface onto which the first light is irradiated and an upper surface serving as a light extraction surface; and a light shielding member surrounding lateral surfaces of the phosphor member. First and second regions of the first light reflecting member are formed such that a portion of the light reflected by the first region that is reflected on a side close to the second region and a portion of the light reflected by the second region that is reflected on a side close to the first region intersect before reaching the lower surface of the phosphor member.
