An ADB high and low beam integrated vehicle lamp illumination module, comprising a low beam primary optical unit (1), a high beam primary optical unit (2), a light shielding plate (3), and a collimating optical element (4). The low beam primary optical unit (1) comprises a low beam light source (11) and a low beam condensing element (12) used for collimating or converging light emitted by the low beam light source (11) and forming a low beam light distribution in the focal region of the collimating optical element (4); the high beam primary optical unit (2) comprises a plurality of high beam light sources (21), a high beam condensing element (22), and a bifocal optical element (23); the high beam condensing element (22) is suitable for collecting light emitted by the plurality of high beam light sources (21) and the light is irradiated to the region of a first focus (F1) of the bifocal optical element (23); a second focus (F2) of the bifocal optical element (23) is located in the focal region of the collimating optical element (4); the light shielding plate (3) is disposed in the focal region of the collimating optical element (4). A low beam light shape and an ADB light shape consisting of the low beam light shape and an ADB illuminated region having a cut-off line can be formed, and an illuminated dark region formed by the ADB light shape is smaller.
