Abstract

An illuminating device according to the present disclosure is of a reflective type and uses a laser beam. The illuminating device includes: a laser element that emits a laser beam; an optical fiber that transmits the laser beam emitted by the laser element; a phosphor layer that converts a wavelength of light incident on one of surfaces and emits the light through the one of the surfaces; and an optical component that causes reflected light of the laser beam transmitted through the optical fiber to be incident on the one of the surfaces of the phosphor layer. With the illuminating device, an intensity distribution of the light incident on the one of the surfaces of the phosphor layer is sparse at a central region.
