    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 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.
