Lighting considerations
1. Half an hour before the opening, turn on all equipment, preheat at low temperature, and test all equipment and lines at the same time. The low temperature state means that the light is slightly bright;
2. After 15 minutes of warm-up, reset all devices to zero, let the devices dissipate heat, and the cooling time should not be less than 15 minutes;
3. After heat dissipation, you can officially enter the stage of music performance;
4. After the performance is over and the guests leave the venue, the lighting engineer should turn off all equipment and let the equipment cool down for 15 to 20 minutes, then seal or cover the equipment before the lighting engineer can leave the venue.
Note: The maintenance of lighting equipment is more complicated and trivial than that of audio equipment. Basically, daily routine testing, weekly regular testing, monthly equipment maintenance and proper debugging are carried out.
Routine testing includes
1. Whether the bulb can be turned on normally;
2. Whether all equipment connections are normal;
3. Whether all equipment can be used normally, including whether the light control switch, color changer control, computer lamp action, etc. are normal;
4. Whether the DMX512 signal can control the lamp normally;
5. Whether the special effect equipment is in normal use and filled with required materials, such as: smoke machine, fog machine, snow machine, bubble machine, etc.; stage lighting;
Regular weekly inspection
1. During the weekly inspection, mainly check the connection of the equipment, including the power connection, DMX512 connection, etc., to see if there is looseness, whether there is a breakpoint, etc.;
2. At the same time, during the weekly inspection, the lamp position and DMX512 programming should be adjusted comprehensively;
Monthly equipment maintenance and appropriate adjustments
In addition to daily monitoring and weekly testing, proper monthly adjustments will be a very meticulous work that requires the coordination of multiple departments, such as actors, bands, weak electricity, security, cleaning, etc. When testing, the following tasks should be completed.
1. Adjustment of light position; because some light positions will be shifted or the guest area will change during use, resulting in changes in light position, so equal position adjustments must be made every month, of course, including computer lights controlled by DMX512 signals ;
1. Adjustment of light position; because some light positions will be shifted or the guest area will change during use, resulting in changes in light position, so equal position adjustments must be made every month, of course, including computer lights controlled by DMX512 signals ;
2. Inspection of mechanical equipment, including scanner motors, color changer motors, special effect equipment nozzles, etc.;
3. Check all lines. Check whether there are breakpoints, damage, and leakage, because it is inevitable that some human factors will cause various accidents in the line during use, such as leaking wires being stepped on, frequently plugged wires or breakpoints, Occasionally, the line leakage or even short circuit occurs due to the spilled drink, so this detection should be very careful. This detection requires weak current to complete;
4. Clean up the dust and garbage inside and outside the lamp. When the lights are in use, there will be some garbage, such as the garbage left in the lamp body after the explosion of the bulb. In addition, the computer lights and special effect machinery that have been exposed for a long time in the audience area are prone to some garbage, such as ribbons, glass shards, drinks and drinks. residue, etc. Therefore, it is necessary to wipe off the garbage and dirt on the outside of the lamp, and remove the garbage inside the lamp. This link requires cleaning cooperation;
5. Check all fire protection equipment. Lighting and audio are the most concentrated types of work in the circuit. Strong electricity enters and weak electricity exits. There are many related equipment and related wires. Therefore, fire prevention is the top priority in lighting work. With the cooperation of the Security Department, a comprehensive inspection is carried out on all fire prevention facilities and fire extinguishing equipment. The scope of monitoring includes the normality of fire protection equipment, whether the selection of fire extinguishing equipment is normal, whether it is within the warranty period, etc.;
In addition, in addition to the above-mentioned daily monitoring, weekly inspection, and monthly comprehensive inspection, the lighting engineer must have a good understanding of all conditions of the equipment and the environment. security.
