The utility model provides an efficient energy-saving signboard which comprises a vertical board, the other side of the surface of the vertical board is electrically connected with a light sensor, one side of the surface of a first supporting plate is in threaded connection with a rotating mechanism, and the other end of the vertical board is connected with a lifting mechanism. According to the signboard, through the arrangement of a second limiting groove, a clamping spring, a limiting column, a sleeve block, a third limiting groove and a second limiting hole, when the signboard is used, due to the characteristics of the clamping spring, the clamping spring can contract under the action force, when the action force disappears, the clamping spring can restore to the original shape, after the limiting column is pressed, the clamping spring can contract, and the limiting column is separated from the second limiting hole; the vertical board can slide up and down in a third limiting groove of the sleeve block and
