Abstract: Disclosed is a uniformly luminous baseball bat, including: a baseball bat body, where a first connector is arranged at a tail end thereof; a mounting base, with one end thereof inserted into the baseball bat body; a condensing lens, which is mounted on the mounting base; a spotlight assembly, which is mounted inside the mounting base; a fastening unit mounted on the first connector, where the mounting base and the spotlight assembly are arranged between the fastening unit and the baseball bat body; and a cover arranged at a head end of the baseball bat body, where a reflective surface is arranged on an inner wall of the cover. The spotlight assembly and condensing lens arranged at a tail end of the baseball bat body ensure that any light beam penetrates through the entire baseball bat body, thereby ensuring uniform illumination of the entire baseball bat body.
