Abstract

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.

First claim

What is claimed is:

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 wavelen…
