A laser collimation unit (2) and a vehicle ultrahigh luminous flux light source module therefor, for use in an intelligent vehicle lamp module comprising a laser source array (1-1), a dynamic transmission type fluorescent wheel (3), a relay lens group (4), a DMD chip system (5-1), and a projection lens group (6). The laser collimation unit (2) is provided between the laser source array (1-1) and the dynamic transmission type fluorescent wheel (3). The laser collimation unit (2) reflects all collimation lights emitted from left and right directions to the same direction by means of a coated reflector array (13) mounted in front of a collimation lens array (10). All parallel lights collimated in the same direction enter a converging lens group (7) located in front of the relay lens group (4) along an optical axis of the converging lens group (7) mounted above the module. Lights emitted by all semiconductor lasers are converged on a point of the front side of a fluorescent ceramic of the relay lens group (4) by
