Abstract

A light source unit includes one or more solid-state light sources and a light collecting optical system. The one or more solid-state light sources are arranged on a rear side of an output portion and each output light in a predetermined wavelength range along the same direction as an optical-axis direction. The output portion includes a light emitter that is excited by the light in the predetermined wavelength range with a predetermined direction as the optical-axis direction to emit visible light in a wavelength range longer than the predetermined wavelength range. The output portion is also capable of outputting light containing the light in the predetermined wavelength range and the visible light from the light emitter along the optical-axis direction. The light collecting optical system collects the light in the predetermined wavelength range.
