Lighting equipment

The utility model relates to the technical field of building equipment, in particular to lighting equipment. The hollow rod is vertically arranged on the ground, the piston with the height adjusted through air pressure is arranged in the hollow rod, the lamp body is arranged on the top of the piston, the rubber ring is arranged on the top of the inner wall of the hollow rod, and the inner wall of the rubber ring makes close contact with the outer wall of the lamp body. A baffle ring is fixedly connected to the inner wall of the hollow rod at the bottom of the rubber ring, and the inner wall diameter of the baffle ring is larger than that of the rubber ring; the piston is matched with the lamp body, the position of the lamp body can be adjusted, dust on the lamp body can be wiped cleanly through the rubber ring when the lamp body moves, the lamp body is kept clean, and therefore the lighting effect of the lamp body is guaranteed, due to the fact that the piston is arranged, the position of the lamp body can be
