Abstract
A head lamp apparatus may include: a light source unit including first and second light sources; a lens separated from the light source unit; a first optic rod having a first light receiving surface, and emitting light received from the first light source toward the lens through a first light emitting surface; and a second optic rod having a second light receiving surface, and emitting light received from the second light source toward the lens through a second light emitting surface. At least one of the first and second light emitting surfaces may be positioned on a Petzval surface of the lens.

A head lamp apparatus comprising:
- a light source unit comprising first and second light sources;
- a lens separated from the light source unit;
- a first optic rod having a first light receiving surface, and configured to emit light received from the first light source toward the lens through a first light emitting surface;
- and
- a second optic rod having a second light receiving surface, and configured to emit light received from the second light source toward the lens through a second light emitting surface,
- wherein at least one of the first and second light emitting surfaces is positioned on a Petzval surface of the lens,
- wherein at least one of the first and second light emitting surfaces is inclined in a direction away from the Petzval surface.
A head lamp apparatus comprising:
- a light source unit comprising first and second light sources;
- a lens separated from the light source unit;
- a first optic rod having a first light receiving surface, and configured to emit light received from the first light source toward the lens through a first light emitting surface;
- and
- a second optic rod having a second light receiving surface, and configured to emit light received from the second light source toward the lens through a second light emitting surface,
- wherein at least one of the first and second light emitting surfaces is positioned on a Petzval surface of the lens,
- wherein the first light emitting surface has a larger area than the first light receiving surface,
- wherein the second light emitting surface has a larger area than the second light receiving surface.

- and
- a second optic rod having a second light receiving surface, and configured to emit light received from the second light source toward the lens through a second light emitting surface,
- wherein at least one of the first and second light emitting surfaces is positioned on a Petzval surface of the lens,
- wherein the first optic rod comprises:
- a first light receiving part having the first light receiving surface formed thereon, and formed in a shape of which a cross-sectional area increases and then decreases toward the first light emitting surface;
- and
- a first light emitting part having the first light emitting surface formed thereon, connected to the first light receiving part, and formed in a shape of which a cross-sectional area increases toward the first light emitting surface.
