  • Patent number: 10017103
    Abstract: A vehicle lighting apparatus includes: a light source device that includes a semiconductor laser which emits laser light and a wavelength conversion member which converts the wavelength of at least part of the laser light and that emits, from a light emission part, light from the wavelength conversion member; a reflection member that reflects light emitted from the light emission part of the light source device in a vehicle frontward direction as parallel light; a light shield member that blocks light which is emitted in the vehicle frontward direction from the light emission part and which is not incident on the reflection member; and a light detection part that is arranged at a vehicle rearward positon of the reflection member and detects part of the light emitted from the light emission part.
