Document Type and Number:
Japanese Patent JP6507828
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a translucent member, an optical member and a light-emitting device having a small configuration that does not obstruct laser light used for a light source.SOLUTION: A translucent member 110 comprises: a laser light passage 113 through which laser light from a semiconductor laser device 122 passes; an incidence surface 111 upon which the light that passed through the laser light passage 113 and obtained by wavelength conversion of the laser light at a wavelength conversion part 132 is incident; and an emission surface 112 that condenses the light made incident upon the incidence surface 111, and emits it as a substantially-parallel light. The laser light passage 113 is configured by a groove or a hole, and is formed so as to be inclined to an optical axis of the light from the wavelength conversion part 132.SELECTED DRAWING: Figure 1
