STAGE LIGHT HAVING CONTROL SYSTEM CONTROLLING COOLING GAS VOLUME

摘要

A stage light, having a control system controlling a cooling gas volume, comprises a light cavity (2) and a light source (1) disposed therein. A light cavity side wall (22) is arranged on one side of the light cavity (2), and a gas inlet is provided on the light cavity side wall (22). The stage light further comprises a gas pumping device (3) communicated with the gas inlet on the light cavity side wall (22). A baffle (5) and driving mechanisms (6, 7) configured to drive the baffle (5) are provided at the gas inlet on the light cavity side wall (22). The driving mechanisms (6, 7) are configured to drive the baffle (5) to move at the gas inlet and change a flow direction, a flow volume, and a flow speed of a cooling gas at the gas inlet. The embodiment is simple in structure and easy to use, and can increase safety and stability of lighting equipment, and prolong a service life of the light source (1) of the stage light.
