How to adjust the professional skills and principles of stage lighting

1. When the light bulb is cooled, the light is slammed, and the light bulb may be broken; or the tungsten filament of the bulb may be blown.

(1) Since the bulb of the bulb is inevitably thick and uneven during the production process, uneven heating is caused.

(2) After the light is used, the bulb will absorb water molecules in the air during the process of cooling from heat, and these water molecules will stay on the glass shell of the bulb to gather. When you slam the bulb, the water molecules on the glass shell seem to be the same as the water in the hot oil pan. It is also a matter of course.

(3) Pushing the light violently will cause an instantaneous surge current (rise), which will easily dissolve the bulb tungsten wire.

Operational skills: When the light bulb is in a cold state (before the opening), push the fader of the console only a little (often said calendering state), so that the bulb is slightly bright, so that it is in the warm-up state, so that it The heat is evenly distributed, and at the same time, the water molecules condensed on the glass envelope of the bulb are evaporated. After preheating for a few minutes, the light is further illuminated, and then preheated for a few minutes before the light is completely illuminated.



2. Never open the silicon box power supply when the dimmer fader is fully pushed. The result is the same as the above result, both of which will damage the bulb. All faders of the dimmer should be turned off, and the silicon box power should be turned on.

3. Never reverse the order of the lamp console and the silicon box power supply when switching the device. When turning on the power, first turn on the power of the light console, then turn on the power of the silicon box; when turning off the power, first turn off the power of the silicon box, then turn off the power of the light control station. If you reverse the sequence of operations, all the lights will flash, which will affect the life of the bulb.

4, should not shake the lamp when the light bulb is on. The tungsten filament of the bulb will break or fall off.

Crimp Tool

Our Remove tool are used to insert and extract terminals from connector housings respectively without damaging the terminal or housing, a key criterion for quality wire processing, especially for OEM and aftermarket rework and repair important.
