Abstract: A light emitting device includes an edge emitting laser chip and a reflecting mirror. The edge emitting laser chip has light emitting ports arranged in parallel in a first direction. The light emitting ports emit light beams in a second direction. The reflecting mirror includes a reflecting surface used to reflect the light beams to a third direction. The first, second and third direction are perpendicular to each other. The light beams are emitted to the reflecting surface through the virtual incident plane and project first light spots on the reflecting surface. Each projected light spot has a first axis length in the first direction and a third axis length in the third direction. An interval between two immediately-adjacent light emitting ports is greater than the first axis length of one of the two projected light spots aligned with the two immediately-adjacent light emitting ports.
