Abstract
The invention provides a vehicle lamp which includes a lens, a lighting module, and a mask. The lens includes an optical axis. The lighting module includes a first LED lighting source which includes a first substrate to dispose a plurality of LEDs on the first substrate and includes a first lighting projection direction parallel to the optical axis for emitting a first light beam through the lens to a projection plane. The mask is located between the lens and the first lighting source, and includes an edge for partially shading the first light beam to form a cutting line between a light area and a dark area on the projection plane. The first LED lighting source is adjacent to the mask in a distance less than 5 mm.
