Abstract:
A light emitting device is provided with a semiconductor light emitting element and a wavelength conversion portion. The wavelength conversion portion includes an outer peripheral portion between an input surface and an output surface. The outer peripheral portion includes a first inclined part at a side of the input surface and a second inclined part at a side of the output surface. The first inclined part and the second inclined part define a projecting portion that is projected on the outer peripheral portion.
