Abstract:
A light emitting device includes a plurality of semiconductor laser elements, a frame part, a light-reflective member, a plurality of wires, and first and second protective elements. The frame part has a pair of first inner lateral surfaces and a second inner surface. The light-reflective member is configured to reflect laser light traveling from at least one of the plurality of semiconductor laser elements toward one of the first inner lateral surfaces of the frame part. The wires electrically connect the semiconductor laser elements respectively to an upper surface of the frame part. The first and second protective elements are disposed on the upper surface of the frame part in an area of the upper surface along the second inner surface. At least one of the wires is bonded on an area of the upper surface between the first and second protective elements.
