Abstract:
A light emitting device includes a plurality of semiconductor laser elements, a light-transmissive member, and a wavelength conversion member. Each of the semiconductor laser elements is configured to emit light having a first wavelength. The light-transmissive member includes a plurality of first inclined surfaces and a lower surface. The light-transmissive member is positioned with respect to the semiconductor laser elements so that beams of the light emitted from the semiconductor laser elements enter the light-transmissive member respectively through the first inclined surfaces and exit from the lower surface. The wavelength conversion member is disposed in contact with the lower surface of the light-transmissive member and configured to convert at least a portion of the light exiting from the lower surface to wavelength-converted light having a second wavelength.
