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.

Abstract: A light emitting device includes a light emitting element, a substrate, and a cap. The cap surrounds the light emitting element disposed on the substrate, and has a plurality of lateral portions including a first lateral portion having a first inner lateral surface through which the light emitted from a light emitting surface and traveling along an optical axis passes, and a second lateral portion having a second inner lateral surface different from the first inner lateral surface. The first inner lateral surface is inclined at a first inclination angle toward a side where the light emitting element is disposed with respect to a plane perpendicular to the mounting surface. The second inner lateral surface is inclined at a second inclination angle larger than the first inclination angle toward a side where the light emitting element is disposed with respect to a plane perpendicular to the mounting surface.

Abstract: A light emitting device includes a base defining a recess, a lid portion, first and second semiconductor laser elements, and a collimate lens. The lid portion covers the recess so that a hermetically sealed space is defined by the lid portion and the base, the lid portion having a bottom surface fixed to the base and a top surface opposite to the bottom surface. The first and second semiconductor laser elements are provided in the hermetically sealed space. The first and second semiconductor laser elements respectively irradiate first and second lights having first and second peak wavelengths in a visible range. The collimate lens is fixed on the top surface of the lid portion with an adhesive. The collimate lens has a plurality of lens portions including a first lens portion through which the first light passes, and a second lens portion through which the second light passes.
