Abstract:
A lighting apparatus having laser light as a light source is provided. The lighting apparatus includes: a light-emitter which radiates light of a wavelength different from a wavelength of the laser light; and a lens including a light distribution controlling structure that controls distribution of the light radiated from the light-emitter. The lens is disposed opposite a laser light entry side of the lighting apparatus. The light-emitter is disposed between the lens and the laser light entry side. The lens integrally includes, along an optical axis of the laser light, a light-dispersing structure configured to disperse the laser light.
