Light emitting device and wavelength conversion member
A light emitting device includes a laser light, a wavelength conversion member, a base member and a lid. The wavelength conversion member includes a plurality of projected portions each extending along a first direction on an upper surface side thereof and arranged side by side in a second direction. Each of the plurality of projected portions has a first surface extending along the first direction. The first surface is inclined with respect to a reference surface. The laser light source and the wavelength conversion member are arranged so that an optical axis of first light from the laser light source extends along the second direction when viewed from above and is inclined with respect to the reference surface, and light directly incident to the first surface along a direction parallel to the optical axis of the first light is regularly reflected toward an upward direction.
