Lamp body installation structure and moving head lamp heat dissipation mechanism

The utility model discloses a lamp body installation structure and a head shaking lamp heat dissipation mechanism, a bulb positioning hole is formed in the middle of a fixing frame of the lamp body installation structure, two fan installation frames are arranged on the two sides of the fixing frame respectively, the overall structure is simple and compact, and material cost can be saved. The flowguide pieces are fixed to the fan mounting frames respectively, heat dissipation airflow sent out by the fans can be guided through the flow guide pieces, the heat dissipation airflow can flow in a concentrated mode, and due to the fact that the air outlets of the flow guide pieces face the bulb positioning holes, the heat dissipation airflow can act on the bulb more accurately, so that the cooling and heat dissipation requirements of the bulb are better met; moreover, the bulb positioning hole is fixed with the position of the fan mounting frame, so that the relative positions of the bulb andthe fan of the lamp body
