The invention relates to a vehicle lamp lighting module, which comprises a concave reflector (2), wherein a light source (S) is installed at least in the concave surface of the reflector to light at least upwards, and a lens (3) is respectively positioned in front of the reflector and the light source. The reflector is related with a flat plate (4), the top surface of the flat plate is light reflecting to buckle the light beam from the reflector, and the flat plate comprises a front end edge which can form a cutting line in light beam. The reflector (2) is fixed to ensure the ball-shaped wavesurface form the light source (S) to be converted into a wave surface identical with an arc (A) positioned on the plane of the flat plate (4), and the lens (3) is rotated along an axle (Z) which is approximately vertical with the plane of the flat plate and penetrates through the circle centre (C) of the arc.
