1. A stage light fixture with a light head having external heat dissipation, comprising:
a light head for projecting light beams, which is formed as a cylinder with a light outlet which is covered by a light emitting lens; and
a support arm for supporting the light head to rotate via a pivoting shaft,
wherein at least one first blower is provided in the support arm, which is configured to blow air around the light head to flow and thus cool outside of the light head, and
wherein at least one effect-forming module is further provided in the light head for changing the light beams generated by a light source inside the light head, including a light shaping component for shaping the light beams, a light filter component for changing color of the light beams, a pattern component for forming light beams with specific pattern, and/or a lens component for changing divergence angle of the light beams.
