Basic knowledge of stage lighting control techniques for performing arts halls

First: In the stage lighting control of the auditorium, if the lighting controller suddenly pushes the light up when the bulb is cold, it is likely to cause the bulb to burst with a "pop"; or cause the bulb tungsten wire to fuse. Faced with this problem, the control technique that our stage lighting controllers should master is when the light bulb is in a cold state (before the opening), push the fader of the console only a little (often referred to as the calender state) , Make the bulb slightly bright, let it in the preheating state, make it evenly heated, and at the same time evaporate the water molecules condensed on the bulb glass shell. After preheating for a few minutes, push it brighter, and then preheat for a few minutes, Only then can the light be fully turned on.

Second: The lighting engineer should remember not to turn on the power of the silicon box when the fader of the dimmer is fully pushed. If the controllers operate in violation of the regulations, the result obtained is still the fault in the first problem mentioned above.

Third: When lighting engineers switch the equipment, remember not to reverse the order of the light console and the silicon box power supply. It is normal for the equipment to be damaged by the incorrect operation sequence. Friends who understand control technology should be very clear about this. .

Fourth: When operating and controlling lighting equipment, do not shake the lamp in a big motion when the bulb is turned on. This problem is rare.

Fifth: Do not touch the bulb directly with your hands when replacing the bulb, which will affect the smoothness of the bulb, and another hidden hazard is causing the bulb to burst. The operating technique we use in this step is to replace the bulb At the same time, be sure to wear gloves before touching the bulb. If you don’t have gloves, you can wrap the bulb with sponge, plastic paper or soft tissue before installing it. After installation, you must remember to remove these wrappers to avoid fire when the bulb is turned on.

Sixth: Don't forget to install the protective net cover while installing the color changer. The protective net cover is to prevent splashes and burns when the bulb explodes.
