Beschreibung
Zusammenfassung:	The light emitting device is provided with a plurality of emitted elements 11, 12 to 1n; a light diffusion element 40 which diffuses emitted light L11, L12 to L1n respectively from the light emitting elements 11, 12 to 1n and outputs diffused light L21, L22 to L2n; and an optical coupling element 50 which receives the diffused light L21, L22 to L2n and outputs the output light L3 that is obtained by coupling the diffused light L21, L22 to L2n. The light diffusion element 40 diffuses the emitted light L11, L12 to L1n into a range that includes the direction of the optical axis of the optical coupling element 50.
