LIGHT EMITTING DEVICE AND LIGHT EMITTING MODULE

WIPO Patent Application WO/2024/070857

A1

A light emitting device according to the present invention includes: a base having a mounting surface; a plurality of semiconductor laser elements each emitting a laser beam in a first direction and arranged on the mounting surface along a second direction intersecting the first direction; a plurality of first mirror members each having a first reflecting surface that reflects the laser beam emitted from the corresponding semiconductor laser element and changing the traveling direction of the laser beam in a direction away from the mounting surface; a cover body that transmits the laser beams reflected by the first reflecting surfaces; and one or more second mirror members arranged on the cover body, having second reflecting surfaces that reflect the laser beams transmitted through the cover body, and further changing the traveling direction of the laser beams. The plurality of first mirror members are arranged on the mounting surface such that positions of the first reflecting surfaces in the first direction are different from one another. With the mounting surface serving as a reference surface, the heights of the optical axes of the laser beams reflected by the second reflecting surfaces from the reference surface are different from one another.
