Abstract
A light emitting device includes: a base portion comprising: an upward-facing surface, and a frame defining an inner lateral surface; a plurality of semiconductor laser elements arranged on the upward-facing surface and surrounded by the frame; a cover portion supported by the frame and disposed above the plurality of semiconductor laser elements; and a protrusion extending from a lower surface of the cover portion toward the upward-facing surface. Light emitted from each of the plurality of semiconductor laser elements is incident on a lateral surface of the protrusion, passes through the protrusion, is reflected at the boundary surface, and is transmitted through the cover portion.
