发明名称 LIGHT EMITTING DEVICE
摘要 The light emitting device according to the present invention comprises a laser diode; a wavelength converting member which is configured to convert a wavelength of a light emitted from the laser diode; and a support member which is configured to support the wavelength converting member so that the light passes through two surfaces of the wavelength converting member. The wavelength converting member comprises a fluorescent material and a binder. At least one light transmissive member is disposed on at least one of these two surfaces of the wavelength converting member. The binder has a melting point higher than a melting point of the light transmissive member. The light transmissive member is fixed to the support member by fusion bonding.
