Abstract
A vehicle lamp, a vehicle, and a vehicle lamp illumination module. The vehicle lamp illumination module comprises light sources, a low-beam primary optical element, a high-beam primary optical element, and a secondary optical element. The low-beam primary optical element can guide light to be sequentially emitted via the low-beam primary optical element and the secondary optical element to form a low-beam shape. The high-beam primary optical element comprises multiple collimation units, wherein the surfaces of light emitting ends of the collimation units are connected together or integrally formed to form a high-beam light emitting surface. Light incident ends of the collimation units have one-to-one correspondence to the light sources, so that the light can be sequentially emitted via the high-beam primary optical element and the secondary optical element to form a lightless shape. The module has accurate light shape control, is precise in assembly, and high in light energy utilization.
