Abstract:
A lighting apparatus which has a light emitter that emits light of a different wavelength from a laser light with which the lighting apparatus is irradiated is provided. The lighting apparatus includes a condenser lens that condenses the laser light, a focusing lens that focuses the laser light that has passed through the condenser lens, and an optical component disposed between the condenser lens and the focusing lens. The optical component includes a plurality of lenses disposed at a plurality of locations on circumferences of virtual concentric circles. The virtual concentric circles include a center which is an origin. Lenses which are adjacent along a radial axis passing through the origin, among the plurality of lenses, have different phases with respect to the radial axis.
