Beneficial effects: two independent light emitting units and optical reflecting systems are provided in one module, and light rays emitted by the two units use the same lens to control emergent light rays, realizing the optimum illuminating effects that when the low beam for automobile illumination is used, a near wide area is focused and lightened, and when the high beam therefor is used, a distant narrow area is focused and lightened.
