The invention relates to a double-focus light energy tracking superconduction lighting device and method. The device comprises a light difference tracking unit and a light ray gathering lighting unit.The light difference tracking unit is composed of four photosensitive sensors, a voltage comparator, a first motor potentiometer, a second motor potentiometer, a steering engine control panel, a two-freedom-degree steering engine holder and a power module. The light ray gathering unit is composed of a concave mirror, a convex lens set and a lighting optical fiber. The physics principle is applied, automatic accurate tracking of the sunlight through the concave mirror is achieved through the light difference tracking technology and the two-freedom-degree steering engine holder; the double-focus technology is adopted, large-area light rays are gathered to the focus point through the concave mirror, small-area, high-density and ultrahigh-brightness light rays at the focus point position arerefracted into parallel li
