Abstract
A light-emitting module includes at least one light-emitting element provided on a mount surface of a substratum. A translucent member is provided so as to face the mount surface of the substratum. The translucent member is separated from the light-emitting element and contains a phosphor material that converts a wavelength of light emitted by the light-emitting element. A frame having heat conducting properties is interposed between the substratum and the translucent member. The frame surrounds the light-emitting element. The frame includes an opening that leads light emitted by the light-emitting element to the translucent member, and a heat conductor thermally connected to the translucent member. The heat conductor includes a heat radiator exposed outside of the translucent member.
