• a light source unit;
• and
• a lens disposed in front of the light source unit, wherein,
• the light source unit comprises:
• a substrate;
• a first light-emitting chip array comprising a plurality of semiconductor-type first light-emitting chips disposed on the substrate and arrayed along a horizontal direction;
• a second light-emitting chip array comprising a plurality of semiconductor-type second light-emitting chips disposed on the substrate and arrayed along the horizontal direction;
• and
• a third light-emitting chip array comprising a plurality of semiconductor-type third light-emitting chips disposed on the substrate and arrayed along the horizontal direction,
• the second light-emitting chip array is disposed on the substrate at a first distance below the first light-emitting chip array in the vertical direction,
• the third light-emitting chip array is disposed on the substrate at a second distance below the second light-emitting chip array in the vertical direction, and
• the first distance is larger than the second distance.
