[0002] With the development of the performing arts industry, lighting engineers have higher and higher requirements for stage lighting equipment, especially for light leakage at the heat dissipation vents of the lamp body structure of stage lighting fixtures.

[0003] The lamps in the prior art are limited by the lamp body structure and heat dissipation requirements, and usually adopt the following design schemes: 1) Reducing the angle of the shutters on the lamp body vents can reduce the degree of light leakage, but it is necessary to increase the wind speed of the heat dissipation fan to ensure the heat dissipation performance of the lamp, which will cause the lamp noise to increase significantly and deteriorate the recording effect of stage performances; 2) Increasing the angle of the shutters on the lamp body vents is conducive to ventilation, which can reduce the fan speed and lamp noise, but the light leakage phenomenon is obvious, which will also deteriorate the stage performance effect; 3) Keeping the angle of the shutters small and keeping the fan speed low can reduce light leakage and reduce noise, but at this time important components of the lamp are prone to overheating.

[0004] In summary, the technical defects of the stage lamps in the prior art are that the structure of the blinds used for shading is difficult to balance the ventilation performance and shading performance, which easily causes problems such as light leakage, overheating or loud noise in the lamps.
