The invention belongs to the technical field of explosion-proof LED lamps, and particularly relates to an explosion-proof LED lamp internally provided with an intelligent inductive control module. TheLED lamp comprises a lamp body shell, a lamp holder, a focusing lens group and a focal length adjusting plate; the lamp body shell is of a cone hopper cavity structure; the lamp holder is fixedly mounted at the closed end of the lamp body shell; an LED lamp bead is fixedly mounted in the middle of the front surface of the lamp holder; four guide holes are symmetrically formed in the corners of the lamp holder; guide rods are movably embedded in the four guide holes; and the ends, located inside the lamp body shell, of the four guide rods jointly support and are connected with the corners of the focusing lens group. A focusing motor drives a cam to rotate, and the cam abuts against the back surface of the focal length adjusting plate in the rotating process to move along the four guide holes; and the distance between the focusing lens group and the LED lamp bead can be adjusted by pushing the four guide rods, so that light rays with different intensities and specifications can be focused, scattered and adjusted in focus to meet the set requirements.
