Abstract:
A light emitting device includes a base; a plurality of semiconductor laser elements that are disposed on the base and that are configured to emit light laterally from the plurality of semiconductor laser elements; a reflecting member that is disposed on the base and configured to reflect light from the plurality of semiconductor laser elements; a surrounding part that is disposed on the base and that surrounds the plurality of semiconductor laser elements and the reflecting member; a wiring part that is disposed on the base so as to extend to a location outside of the surrounding part, the wiring part being electrically connected to the plurality of semiconductor laser elements; a radiating body disposed on the surrounding part, the radiating body comprising at least one of a metal and a ceramic, and the radiating body having an opening; and a wavelength converting member that is located in the opening of the radiating body, the wavelength converting member being configured to convert a wavelength of light that is emitted from the plurality of semiconductor laser elements and reflected upward by the reflecting member.
