A intelligent long-distance infrared fill-light set for illuminating a predetermined target range at least 500 meters away cooperates with an infrared image-acquisition equipment to obtain an image of an illuminated-object, and includes: infrared fill-lights each including an optical lens, optical axis passing through a focus, infrared light sources emitting an infrared beam having a main beam angle, to generate a substantial overlapping area and at least one non-overlapping area when illuminating to the predetermined target range; enabling devices that enable light sources; and a control unit receiving image data acquired by the infrared image-acquisition equipment, for calculating and adjusting the enabling device to locally strengthen or weaken the substantial overlapping area and/or non-overlapping area. Infrared fill-lights are spaced a predetermined distance, so that the human eyes accidentally entering a predetermined dangerous illumination range will not be simultaneously illuminated by infrared beams, thereby avoiding exceeding a Maximum Permissible Exposure (MPE).
