Lighting apparatus for vehicle

A lighting apparatus for a vehicle, comprising:

• a lens;
• a reflection unit;
• a light source device disposed behind the lens, wherein the light source device is configured to emit a beam toward the lens;
• a phosphor assembly configured to convert a wavelength of an incident beam and to emit light having the converted wavelength toward the lens,
• an auxiliary reflection unit disposed apart from the reflection unit;
• a sensing unit configured to sense light that is emitted by the phosphor assembly and reflected by the auxiliary reflection unit;
• and
• a controller configured to control the light source device based on information sensed by the sensing unit,
• wherein the phosphor assembly comprises:
• a phosphor configured to emit the light having the converted wavelength of the incident beam;
• and
• a reflector comprising a plurality of reflective guide walls configured to reflect the light having the converted wavelength emitted by the phosphor,
• wherein the reflector comprising the plurality of reflective guide walls defines at least one space through which the light having the converted wavelength emitted by the phosphor is guided by the plurality of reflective guide walls, and
• wherein the reflection unit is disposed between an optical axis of the lens and a peripheral surface of the lens.
