Abstract
A light emitting module is provided with a light emitting element and an optical wavelength converting member. The optical wavelength converting member includes a light incident plane, a light output plane, and an outer plane which is a plane except for said light incident plane and said light output plane. The optical wavelength converting member converts a wavelength of light emitted on the light emitting element and entered from the light incident plane into the optical wavelength converting member and outputs the wavelength-converted light from the light output plane. An average roughness 'Ra' of at least a portion of the outer plane is lower than an average roughness of the light output plane.
