secret of making stage lighting live long

- Nov 28, 2019-

Half an hour before the opening, open all equipment, conduct low-temperature preheating, and detect all equipment and lines at the same time. The low temperature state means that the light is slightly bright.

Turn on the machine and preheat it for 15 minutes, then reset all equipment to zero to let the equipment cool down for at least 15 minutes.

After cooling, you can officially enter the stage of music performance.

Atthe end of the performance and after the guests leave the venue, the lighting engineer shall turn off all equipment and allow the equipment to dissipate heat for 15 to 20 minutes, then seal or mask the equipment, and then the lighting engineer can leave the venue.


II. Routine testing scope

Whether the bulb can be normally lit. Whether all equipment wiring is normal. Whether all equipment can be used normally, including lamp control switch, color changer control, computer lamp action, etc.

Whether the lamp can be controlled normally. *Whether the equipment is in normal use and filled with required materials, such as: cigarette machine, fog machine, snowflake machine, bubble machine, etc.


III. regular inspection every week

In addition to the daily monitoring

In addition to all projects, the following points should be noted:

During the weekly inspection, it mainly tests the connection of equipment, including the power connection, DMX512 connection, etc., to see if there is looseness, breakpoint, etc. At the same time, during the weekly inspection, the lamp position should be adjusted comprehensively.

IV. monthly equipment maintenance and proper adjustment

In addition to the above-mentioned daily monitoring, weekly inspection and monthly comprehensive inspection, the lighting engineer must have a good understanding of all the conditions of the equipment and the environment, so that if something happens, please deal with it in time, so as to get a good visual environment and have sufficient security.

Lamp position adjustment: because some lamp positions will move or the change of the guest area will occur during the use, the lamp position will change, so the level adjustment will be carried out every month, including the DMX512 signal controlled computer lamp.

Inspection of mechanical equipment: including computer lamp motor, color changer motor, nozzle of * equipment, etc.

Check all lines: check whether there are breakpoints, damages and leakage, because some human factors inevitably cause various unexpected conditions in the use of the line, such as exposed wire is broken, frequently inserted or pulled wire or breakpoints, occasionally leakage or even short circuit due to the line sprinkled with drinks, etc., so this test should be very careful. This test needs weak current to complete.

Clean the dust and garbage inside and outside the lamps. There will be some garbage in the use of the light, such as the garbage left in the lamp body by the explosion of the light bulb, in addition to the computer lights and * machines exposed in the audience area for a long time, which are easy to fall into some garbage, such as ribbon, glass ballast, residual liquid of drinks and so on. Therefore, it is necessary to wipe the garbage and dirt outside the lamp and remove the garbage inside the lamp, which requires cleaning cooperation.

Check all fire protection equipment. Lighting and acoustics are a relatively centralized type of work in the circuit. Strong current enters and weak current exits. There are many related equipment and more related wires. Therefore, fire prevention is the top priority in the lighting work. In the monthly routine inspection, cooperate with the security department to conduct a comprehensive test on all fire prevention facilities and fire-fighting equipment. The monitoring range includes the normal degree of fire-fighting equipment and the selection of fire-fighting equipment Normal, within the shelf life, etc.


In addition to the above-mentioned daily monitoring, weekly inspection and monthly comprehensive inspection, the lighting engineer must have a good understanding of all the conditions of the equipment and the environment, so that if something happens, please deal with it in time, so as to get a good visual environment and have sufficient security.
