The invention provides a lamp heat dissipation structure and an explosion-proof illumination terminal, and belongs to the field of illumination equipment. The structure comprises a front shell, a rearshell arranged on the rear side of the front shell, a touch screen arranged on the front side surface of the front shell and a display screen arranged on the back side of the touch screen, and further comprises a heat dissipation frame which is arranged on the rear side of the display screen and is connected with the front shell, an opening is formed in the middle of the heat dissipation frame, and the front side surface of the heat dissipation frame is used for being in contact with the rear side surface of the display screen. According to the lamp heat dissipation structure and the explosion-proof illumination terminal, through arrangement of the heat dissipation frame, the display screen can carry out dual heat dissipation through the heat dissipation frame and the air, so that the heat dissipation efficiency is effectively improved; and the heat dissipation frame is simple in structure, the fixing effect on the display screen is further realized due to the fact that the heat dissipation frame is directly mounted on the front shell, the stability of the structure is enhanced, and the mounting and fixing structure of the display screen is further simplified.
