The invention relates to a temperature control safety explosion-proof lamp. The temperature control safety explosion-proof lamp comprises a shell, a lamp piece and a lampshade. A good-heat-conduction heat dissipation block is attached to the back face of the lamp piece, annular cylindrical partition plates are mounted in the shell, and two cavity dividing plates are symmetrically mounted in a sealed annular cavity defined by the partition plates, the shell and the lamp piece; the annular cavity is divided into two independent semicircular liquid storage cavities through the cavity dividing plates, and horizontal semicircular piston pieces are mounted in the liquid storage cavities; the positions above the piston pieces are filled with a cooling agent, and the positions below the piston pieces are filled with air and expansion glue; and cooling holes communicated with the cooling agent are formed in the upper portions of the partition plates, and air inlet holes are formed in the lower portions of the partition plates. According to the explosion-proof lamp, the temperature inside a lamp body can be effectively reduced, safe and stable running of the explosion-proof lamp can be ensured, meanwhile, the explosion-proof lamp has the shutoff protection function, and the phenomenon that after the lamp body is exploded, electric sparks are still generated is effectively avoided.
