Claim Text:
1. A light emitting device comprising: a laser diode; a wavelength converting member configured to convert a wavelength of light emitted from the laser diode, wherein the wavelength converting member comprises a fluorescent material and a binder; a support member having a through-hole, the support member being configured to support the wavelength converting member such that the light enters the wavelength converting member via a lower surface of the wavelength converting member, and exits the wavelength converting member via an upper surface of the wavelength converting member; and a light transmissive member fixed to an inner wall of the through-hole of the support member and to the upper surface of the wavelength converting member by fusion bonding, the light transmissive member comprising a fluorescent material, wherein the binder has a melting point higher than a melting point of the light transmissive member, and wherein an upper surface of the light transmissive member and an upper surface of the support member are substantially coplanar.
