Abstract:
A light-emitting device including: a base which is translucent; a semiconductor light-emitting element provided on the base; a sealing member for sealing the semiconductor light-emitting element and including a first wavelength conversion material for converting a wavelength of light emitted by the semiconductor light-emitting element to a predetermined wavelength; and a groove provided on a side of the semiconductor light-emitting element, recessed from a top surface of the base on which the semiconductor light-emitting element is provided or a back surface of the base which is a surface opposite to the top surface, and for holding a second wavelength conversion material for converting the wavelength of the light emitted by the semiconductor light-emitting element to the predetermined wavelength.
