What is the silicon box in the stage light? Is it similar to the distribution cabinet, and what is the difference between the distribution cabinet? What does "digital silicon box" mean? Why do digital silicon boxes require DMX512 signal input? Adjust the brightness of the lights, the lighting console can do exactly, why use digital silicon box?
Silicon box is a regulator of the traditional incandescent lamp lamps (such as a PAR lamp, lantern) the brightness of the device, the output voltage can be adjusted between 0-220V, so as to control the brightness of the lamp. Therefore, the silicon box generally does not need to supply the stable voltage lamp supply, for example shakes the head lamp, otherwise can damage the lamp.The digital silicon box is relative to the silicon box that is controlled by the old analog signal.The old analog signal control silicon box can be controlled by a special control panel, each output corresponds to a control signal, the control signal changes between 0-10V, and the output of the silicon box changes with the 0-220V. Some silicon boxes come with brightness adjustment potentiometer, which can be used independently.A digital silicon box is a silicon case that can be controlled by DMX512 signals. The basic principle is the same as the analog silicon box, but the control signal is changed from analog signal to digital DMX512 signal.The advantage of digital silicon boxes is the use of DMX512 control signals. In this way, traditional lamps and modern computer lights can be controlled by a digital light console, which is convenient for lighting control.
The main function of the digital silicon box is to adjust the brightness of the light through the size of the voltage
The two silicon box is actually the same thing, only one with the analog signal is a digital signal that is almost a power distribution cabinet, two kinds of silicon box can be connected with the DMX512 signal, the basic working process is such that the encoder is silicon box, such as silicon box 24 of the 8 in a row, each row has a coder, from top to bottom, the first encoder dial 1, second encoder dial 9, third is 17, the console write routine lamp library connected to the 512 signal line, is connected to the console silicon box, push up 1~8 lights, signal transmission to the silicon silicon box, box can output voltage of 1 to 8, the lamp opening, according to the signal intensity is different, the output voltage ranging from 0V~220v, so you can control the brightness of the light (silicon box can only control the conventional lamp and some by voltage regulation devices, and silicon box set) can A series of 512 signal lines can be connected in series with 512 silicon paths, and can be connected to more than 21 silicon boxes by 24 silicon boxesAnd you say what kind of lighting console has basically been withdrawn from the market, the console comes SCR, the disadvantage is silicon road is too small, the maintenance cost is high, the effect of editing and output signal are only responsible for the lighting lamp control table
The silicon case is a dimmer circuit using a bidirectional thyristor (similar to a fan governor)Manual dimming circuit or speed control circuit is to change the reference voltage of the entire circuit to change the phase of the output voltage and current to achieve speed regulation or dimmingDigital silicon box is to use the DMX512 convenient remote control box inside the silicon thyristor duty cycle dimming, dimming the benefits in the way that can be used directly to program Taiwan light dimming, eliminating manual dimming trouble is easy to control.The lighting console output is the low voltage control signal can not be directly used for lamp brightness, some smaller silicon controlled Taiwan is with thyristor silicon controlled circuit, but considering the heat problem, each power station is not the silicon control.Distribution cabinet is generally the stage with air box type mobile electric cabinet, mainly provides shunt control lights, leakage protection, over-current protection, voltage fluctuations can also relieve the excessive power supply network caused by the lamp start at the same time. But when it does not have the brightness adjustment function. Electric power all light, all gray.
