Abstract:
A vehicle lighting apparatus that illuminates a frontward direction of a vehicle includes: first and second light source units each having a light source main body and a light-focusing optical system that focuses light emitted from the light source main body; a reflection-type digital light deflection device that is configured by arranging a plurality of mirror elements each of which can be slanted around a rotation movement axis and each of which can be individually switched between an ON slanted state and an OFF slanted state and that reflects the light, focused by the first and second light source units, by the mirror element of the ON slanted state to form a reflection pattern; and a projection optical system that illuminates a frontward direction with light reflected by the reflection-type digital light deflection device, wherein light incident on the reflection-type digital light deflection device by the first and second light source units is overlapped.
