The invention relates to an automobile lamp LED high-low beam integrated PES unit with an ADB function. A high-beam LED circuit board small assembly, a low-beam LED circuit board small assembly and a reflector are arranged in an optical module. A condenser is fixedly arranged right in front of the high-beam LED circuit board small assembly. When the low-beam LED circuit board small assembly works, light rays are reflected to a second focus by the reflector; most light rays are directly emitted into a lens, and small part of the light rays are refracted to enter the condenser and are then subjected to total reflection and refraction again on the front end face and the lower surface of the condenser correspondingly, so that the small part of the light rays do not enter the lens; thus a shading function is achieved, and in this way, the light emitted from the lens can form a low beam shape with a cut-off line. When the high-beam LED circuit board small assembly works, after being focused at the second focus by the condenser, part of light rays are directly emitted and then emitted into the lens; part of the light rays are subjected to total reflection when meeting the upper surface of the condenser, are emitted from the front end face of the condenser, and then emitted out after being emitted into the lens; thus a high-beam function is achieved.
