Heat dissipation structure of waterproof moving head lamp

The utility model provides a waterproof moving head lamp heat dissipation structure which comprises a rocker arm which is of a U-shaped structure and comprises a connecting base at the bottom and vertical connecting arms on the two sides. The rocker arm is rotationally connected to the base through a rotating shaft in the vertical direction; the lamp tube is rotationally connected between the two connecting arms; a communicated ventilation channel is arranged at the connecting position of the lamp tube and the connecting arm, and a communicated ventilation channel is arranged at the connecting position of the base and the connecting base. According to the moving head lamp, the lamp tube is communicated with the rocker arm, heat of a heat source can be dissipated by conducting hot air on the whole communicating path of the rocker arm and the lamp tube through the multiple oriented fans, the purpose of heat dissipation is achieved accordingly, the structural design is ingenious, and the heat dissipation capacit
