Abstract
A vehicle lighting device can include a plurality of semiconductor light-emitting devices and a projector lens configured to illuminate a front of a vehicle with light emitted from the semiconductor light-emitting devices. The projector lens can include a plurality of incidence surfaces which perform main control of light distribution, and respectively correspond to the semiconductor light-emitting devices. A single exit surface of the projector lens can include a plurality of exit regions which emits light entering through the incidence surfaces into the projector lens, wherein the exit regions provided next to each other overlap with each other.
