Abstract: A fluorescent module includes a fluorescent member, a heat dissipation member, and an optical relaxation member. The fluorescent member includes a phosphor-containing layer, and a light reflecting layer. The fluorescent member is secured to the heat dissipation member so that the light reflecting layer is arranged between the phosphor-contacting layer and the heat dissipation member. The optical relaxation member is configured to absorb and/or diffuse light. The optical relaxation member is arranged with respect to the fluorescent member so that the light reflecting layer is arranged between the phosphor-containing layer and the optical relaxation member.

Abstract: A light emitting device can further improve light extraction efficiency. A method of manufacturing such a light emitting device can also prove advantageous. The light emitting device includes a light emitting element, a light-transmissive member which is disposed on a light extracting surface side of the light emitting element, and a reflecting layer disposed on an element bonding surface of the light transmissive member where the light emitting element is disposed and adjacent to the light emitting element. The light-transmissive member, in a plan view, has a planar dimension greater than the light extracting surface of the light emitting element.

Abstract: A fluorescent module includes a fluorescent member including a phosphor-containing layer, and a light reflecting layer disposed on the phosphor-containing layer. The phosphor-containing layer contains a YAG phosphor and a Ga-YAG phosphor within the same layer, the Ga-YAG phosphor being a phosphor in which a portion of the aluminum constituting the YAG phosphor is substituted with gallium. A volumetric ratio of the Ga-YAG phosphor to the entirety of the YAG phosphor and the Ga-YAG phosphor is in a range of 19.0% to 80%.

Abstract: A light emitting device includes a laser light, a wavelength conversion member, a base member and a lid. The wavelength conversion member includes a plurality of projected portions each extending along a first direction on an upper surface side thereof and arranged side by side in a second direction. Each of the plurality of projected portions has a first surface extending along the first direction. The first surface is inclined with respect to a reference surface. The laser light source and the wavelength conversion member are arranged so that an optical axis of first light from the laser light source extends along the second direction when viewed from above and is inclined with respect to the reference surface, and light directly incident to the first surface along a direction parallel to the optical axis of the first light is regularly reflected toward an upward direction.
