Abstract: A lighting device is provided which includes: a wavelength converter that emits, from laser light, light having a wavelength different from a wavelength of the laser light; and a reflector surrounding the wavelength converter and including a surface of revolution that reflects the light emitted from the wavelength converter. The reflector includes, in the surface of revolution, a through-hole through which the laser light passes.
