1. A lamp unit comprising:
- a first substrate;
a second substrate disposed on the first substrate; and
a plurality of light sources disposed on the second substrate, wherein at least two light source arrays are provided, in each of which a plurality of the light sources are disposed in a row, wherein at least a first light source array and a second light source array among the light source arrays are individually driven, wherein the first light source array is supported by a first surface of the second substrate, wherein the second light source array is supported by a second surface of the second substrate, and wherein an angle between the first surface of the second substrate facing the first light source array and the second surface of the second substrate facing the second light source array is from 91 to 179 degrees.

21. A vehicle lighting system comprising:
-
a sensor unit sensing ambient conditions of the vehicle; a head lamp including a lamp unit which includes a first substrate, a second substrate disposed on the first substrate, and n number of light source arrays (n is an integer equal to or greater than
2) formed by disposing a plurality of light sources on the second substrate, wherein the light source array includes a first light source array and a second light source array, which are adjacent to each other, are electrically isolated from each other and are individually driven; andan electronic control unit individually driving the first light source array and the second light source array in accordance with the sensing result produced by the sensor unit, wherein a surface of the second substrate includes a planar surface and an inclined surface relative to the planar surface where an angle between the planar surface and the inclined surface is between 91 to 179 degrees, the first light source array provided on the planar surface and the second light source array provided on the inclined surface.
