Abstract: A projection apparatus of the present disclosure includes a light-emitting element for emitting excitation light, a wavelength converter for receiving the excitation light, converting the excitation light into light of a different wavelength, and emitting the converted light as radiation light, and an optical filter for receiving the radiation light. The optical filter reflects long-wavelength light of wavelengths longer than wavelengths of the radiation light. With this configuration, the optical filter reflects long-wavelength light of wavelengths longer than wavelengths of the radiation light, thus being able to prevent the wavelength converter from being irradiated with long-wavelength light, and being able to prevent deterioration of the wavelength converter.

Abstract: The present disclosure aims to enhance controllability of a lighting apparatus and increase durability. A lighting apparatus includes a light source; a condenser that converges first light emitted from the light source onto a predetermined focal position of a wavelength conversion element as converged light; the wavelength conversion element that receives the converged light and emits second light at an emission point; and a projection lens that projects the second light as projection light. The lighting apparatus changes the focal position of the condenser lens to change the emission point of the second light to the projection lens, thereby being capable of projecting the second light in any direction.
