Lighting apparatus

Abstract

A lighting apparatus includes a light-emitting unit that emits light in a first wavelength band; a phase modulation unit that performs spatial light phase modulation on incident light from the light-emitting unit; a wavelength conversion unit that wavelength-converts incident light from the phase modulation unit, thereby emitting light in a second wavelength band different from the first wavelength band; and a lens optical system that guides emitted light from the wavelength conversion unit to a projection lens, in which the phase modulation unit generates a reproduction image that is formed in the wavelength conversion unit as a reproduction image of the first wavelength band, and the lens optical system forms a reproduction image of the second wavelength band in an optical path between the projection lens and the lens optical system on the basis of the emitted light from the wavelength conversion unit.
