Description
Technical field
The present invention relates to the light modulation field of light of stage, particularly a kind of mechanical dimming system for light of stage.
Background technology
In the mechanical light modulation field that is used for light of stage, mechanical light modulation specification requirement light modulation is even, and requires its gradual transition, requires simultaneously light modulation frame for movement space small and exquisite; In addition, require again this equipment safe and reliable to operation, avoid the scene effect of performing not good.
Traditional light mechanical dimming system comprises two groups of light modulation sheet metals, is fixed with the effect sheet on the sheet metal.These two groups of sheet metals carry out the light modulation campaign separately under two groups of stepper motors drive.This structure has realized the mechanical light modulation function.But in this traditional mechanical light modulation structure, sheet metal one end directly is fixed on the output shaft of stepper motor, and the heat that motor movement produces is directly delivered on the sheet metal.Under the effect of high temperature or external force, this sheet metal is out of shape easily.And other parts of sheet metal all are in vacant state.In this case, other parts are owing to being subjected to force unbalance to produce resonance, thereby affect dimming effect.
Again because the respectively motion under two groups of stepper motors drive of these two groups of sheet metals even strictly control each start-up parameter of these two groups of motors, can not guarantee the motion Complete Synchronization of two groups of sheet metals.In addition, must keep enough gaps between these two groups of sheet metals, prevent that two groups of sheet metals from moving to a place, and the light modulation support plate length that is used for installing sheet metal and stepper motor is limited.So this gap both can affect the even transition effect of light modulation, can affect again the whole size of this system.
Again, the effect sheet that is fixed on the sheet metal will strictly be controlled weight, and in the rapid movement process of mechanical light modulation, the inertia force of its generation can cause the motor desynchronizing phenomenon, has therefore restricted the application of effect sheet, has also affected its effect of heat insulation.
In sum, present mechanical dimming system major defect is the inappropriate mounting means of sheet metal, and this kind mounting means not only causes its life-span of the easy deformation effect of sheet metal, also causes sheet metal to produce the resonance affects dimming effect.
