AI summary

The present invention discloses an internal-circulating heat dissipation system for a stage light, the system comprising a support arm, a light holder and a circulating heat dissipation system, wherein the light holder is pivotally connected to the support arm through a pivot shaft, the pivot shaft is of a shaft pipe structure, an internal space of the light holder is in communication with an internal space of the support arm through the pivot shaft, the circulating heat dissipation system comprises a cooling medium, a heat dissipation component located inside the support arm, and a power component that promotes the cooling medium to flow in circulation between the light holder and the heat dissipation component through the shaft pipe structure, and the cooling medium is isolated from an external space of the stage light. The cooling medium is driven by the power component to flow in circulation between the light holder and the support arm through the pivot shaft of a shaft pipe structure, so that the heat inside the light holder is brought out, and heat dissipation is performed by the heat dissipation component at the support arm, thereby enlarging the heat dissipation space and improving the heat dissipation efficiency while ensuring the leak tightness of the light holder. Moreover, since the heat dissipation component is arranged inside the support arm, the volume of the light holder is effectively reduced as compared with the previous case in which the heat dissipation component is arranged inside the light holder.
