College】 【weak control stage lighting techniques and taboos.

<br> the saying goes, no rules too hard radius. .Therefore, control of lighting, you can not have any arbitrary, because the lighting operation of control has its own norms and skills, otherwise it may cause light bulbs, lamps, lighting control units of the damage, and even cause fires, causing serious damage. .<BR> <BR> Here is the actual work that often appear in the misuse, to point out, learn a lesson. .<BR> <BR> 1. .In the cold light bulb state, suddenly push the light (full) light, the result may cause the light bulb, "pop" sound decrepitation; or cause tungsten lamp fuse. .<BR> <BR> (1) the light bulb in the production process, the glass bulb shell thickness inevitably uneven, leading to uneven heating of the phenomenon. .When suddenly push the light bulb will cause the glass bulb shell moment to heat up, as if to a life filled with empty glass in boiling water the same effect. .<BR> <BR> (2) After finished using the lights, light bulbs by the thermal cooling process, will absorb water molecules in the air, the water molecules will remain in the bulb's glass shell gathering. .When you suddenly push the light bulb, the glass shell of water molecules, as if in hot oil with the same effect in water, light bulbs decrepitation is also logical thing. .<BR> <BR> (3) suddenly push the bright lights will cause an instant impact on the current (higher), so easily off the lamp tungsten solution. .<BR> <BR> Operating skills: When the light bulb in the cold state (before the opening ago), it will only push the fader control of Taiwan from the point (often said that the calendar status), so that little light bulb, let it at .In the warm state, to heat evenly, while evaporation of condensation on the bulb glass shell of water molecules, preheat a few minutes later, pushed a little brighter, then warm after a few minutes, before shifting the light will light. .<BR> <BR> 2. .Avoid pushing the fader dimming full state, then open the box the power of silicon. .As a result, and the result is the same, and both can damage the bulb. .All units should be dimmer fader is turned off, open the silicon case the power line. .<BR> <BR> 3. .Never in the switch device, the lamp power control units and reverse the order of silicon box. .Power is turned on, first turn on the light the power console, and then open the box of the power of silicon; turn the power off, turn off the power silicon box, turn off lights after the console's power. .If you reverse the order of operations, then the line will cause all lights are flashing about, so will affect lamp life. .<BR> <BR> 4. .Avoid pushing the bulb light, the big action rock lamps. .Tungsten light bulb will therefore break or fall off. .<BR> <BR> Light bulb, the temperature gradually increased, a corresponding tungsten become soft, as well as by the influence of gravity, tungsten sagging accordingly (if the bulb is not using the screw-shaped tungsten wire, .This phenomenon is particularly obvious), then shake the lamp when the big move, we must wait until the light completely cooled, removable side. .<BR> <BR> 5. .Never replace the lamp, direct hand contact with light bulbs, which will affect the finish of the lamp, and the other hidden hazards caused decrepitation bulbs. .<BR> <BR> (1) grease on your fingers or fingers with the bulb's glass surface friction would leave "scars", which affects the smoothness and transparency of the lamp so the normal illumination of the light bulb. .<BR> <BR> (2) If there is sweat on the fingers, fingers and the lamp "close" contact, the sweat of the salt molecules will absorb water molecules in the air, once the lamp on the water, when the light bulb when the temperature rapidly to .very easy to decrepitation of the. .<BR> <BR> Operating skills: when replacing the lamp, be sure to wear gloves, and go touch the lamp. .If there are no gloves, light bulbs are available packaged sponge, a soft tissue paper or plastic wrap, and then install, after installation, be sure to remember to take down these inclusions, so as not to push the light bulb in a fire. .<BR> <BR> 6. .Avoid exposure to light back out of tune too much focus on the speed of light. .Focus will be too short to be installed on the light color on paper, color fades, loss of color or, worse, the color of paper burning of a hole. .If the distance between lamps and flammable items direct too close, there may be no point then. .<BR> <BR> Operating skills: adjusting the light beam irradiation, the tone was a little astigmatism that is better, if it is not enough illumination, can add lamps. .<BR> <BR> 7. .Avoid color changers installed at the same time forgot to install protective nets, protective nets to prevent the explosion splash wounding and light bulb burns <BR> <BR> items like back light 2 block pendant no slot, by which a file .install protective nets are used, and out of a block is loaded color Used for change, and some have been fixed within the PAR lamp protective net cover, which is not very good for it? .<BR> <BR> 8. .Remember the hot light of the lamp and the flammable curtain from too "intimate." .Many years ago, a school in the Northeast during a performance, it is because the light will light curtain caught fire, causing hundreds of deaths and injuries in the tragedy. .Therefore, the lighting and curtain to maintain a certain distance between the light induced important. .300W lamp in the direct direction and distance of the curtain not less than 3cm, side lamps, rear and curtain (static state) must be located no less than 2m, if the magnitude of swing big screen, there may be close to the lamps, the best in lighting .and the establishment of a metal screen in the middle of the isolation network, to prevent the screen was set in the fixture and cause a fire. .500W or more lighting, direct distance of 5m outside the curtain, side, rear and curtain from the outside in the 3m. .<BR> <BR> 9. .Lighting will be installed should not exceed the manufacturer under the power of power. .Light on the silicon box the power carried by each loop are detailed in the manual instructions. .Generally speaking, each loop carrying power has 1KW, 2KW, 3KW, 6KW. .Take 6KW example, the silicon inside the SCR, also known as solid state relays are 60A, calculation, can carry the power is 13. 2KW, anyway, there is so much power space in the back on the road to install more than 6KW .light of the. .In my opinion, only consider the light bulb moment generated by the fusing current, so consider the problem of one-sided. .Manufacturers will not be for nothing left to say such a high-power thyristor, which is a grain of truth inside. .It, said one example. .<BR> <BR> A four star hotel's engineering staff, was found in the maintenance room lamps, bedside lamps in a 60W incandescent bulb burned out, also found under the jurisdiction of the lamp is also a 6A fuse .fuse, and we all know, a 60W incandescent light bulb in the operating current of 0. 27A, that is in the fuse 60W tungsten light bulb moment, generated more than 6A current, excluding the insurance management of the margin of error of 1A, then .That light bulb is its instantaneous current fuse operating current of 5 times. .Silicon box manufacturers in the design of each circuit of the thyristor current actual load current is 2.2 times that of gas a bit too small, so the use of light control units for some time, will find more damage as the light bulb .more, silicon is also the breakdown inside the SCR, Always turn off lights not dimmable or not the phenomenon accordingly increased noticeably. .<BR> <BR> 10. .Avoid connecting the load, resulting in three-phase imbalance. .As we all know, the light input power silicon case, most three-phase four-wire system. .Lighting load in the box when connected to the silicon, if not through the allocation to blindly light loads of connections, it may result in phase imbalance occurs. .So, when pushed bright lights, you will feel the difference in light between the light and shade. .<BR> <BR>, For example, have a dimmer circuit 18 sets, it carrying power of each circuit is 6KW, input power 380V, it's 1-6 in C-phase circuits. .Did not take the load before the measurement with a multimeter A, B, C, three voltage relative to the zero line are 220V. .Assuming a silicon box loop were picked 1-6 36KW lighting load circuits, 7-12 took a total of 13-18KW lighting load took a total of 18 circuit lighting 6KW load. .This case will be pushed all the lights lit, and then measuring multimeter, A relatively small change measurements are 200V, C is the relative change measurements 220V, this is the phase imbalance phenomenon, which tells us that the more load ., voltage drop, the more obvious one phase voltage and low voltage is higher than that of a light phase of the light intensity is significantly lower. .<BR> <BR> Operating skills: In addition to install the lights in 3 equal to the total power allocated to each phase of power. .Take the example of the power numbers as an example: 600KW addition to 3 is equal to 20KW, that 1-6,7-12,13-18 loops of the load of each phase 20KW, this three-phase voltage balance. .<BR> <BR> 11. .Should not arbitrarily adjust the lighting on the rated voltage selector switch. .Imported lamp beside the power cord can be adjusted to establish a variable voltage switch gear, above 110V, 220V240V 3-block selection, if the block will be set when transferred to 110V, and the current operating voltage is 220V, then they would .fire insurance, a serious power transformer will burn out. .If the profile when transferred to 240V, so the current-voltage and higher than 20V, this will cause the computer lights have enough power. .<BR> <BR> Previously used a computer scan of early American production of light bulbs it is a 24V, 250W halogen bulbs, but also with the German Osram bulbs, but only less than a light bulb .week burned out, the only way such a good bulb life it? .Later, accidentally with a multimeter to measure its supply voltage is 240V, while the line and the line voltage between 390V-400V, That suddenly realized, because the hotel with a dedicated transformer, the voltage is relatively higher, so the computer lamp to lamp for .The corresponding voltage power will be higher, thus shortening lamp life. .<BR> <BR> Operating skills: Choose rated voltage block when local conditions, based on the current value of the supply voltage to select the gear, if the unit has a dedicated transformer, and you're using light to measure the peak of the high supply voltage .circumstances, may apply to the Engineering Department will be dedicated transformer to reduce voltage block of a block, to protect and prolong the life of all the light bulbs. .<BR> <BR> In addition, special transformers to adjust the voltage block, is not eternal, according to different seasons power usage, to adjust the voltage. .If the units do not have dedicated transformers, but by external transformer power supply, it would have to buy a 380V high-power power supply, the supply voltage within the normal range as well. .<BR> <BR> 12. .Remember to not take the situation firmly under the public use of the zero line of the light. .Six months ago, I helped in a television studio inside the studio is preparing to record a show case, and this time next to the power distribution room, the one being installed Xintian of a large-scale equipment, the construction side did not promptly notify the recording .side, without pulling the case of the total gate, without the zero line of the bolt release the public, prepare the equipment up on the zero line in parallel. .Results lighting division without the knowledge of the use of the bulb, causing light bulbs decrepitation, also caused a small silicon inside the A-phase transformer burned out. .<BR> <BR> Reasons: When the public release after the zero line, the inductance of the transformer EMF generated by the zero line to the lamps to produce a loop, a phase in the formation of a lighter load of high pressure, burned out light bulbs and .silicon box of the transformer. .<BR> <BR> Operating skills: the installation of lighting is used, the land bordering the lighthouse where the bottom deepened 1.5M to fight a long iron bar, iron bar connected to a 6MM2 in the copper wire, copper wire also .one end connected to the light line the shelves of public zero, so even if the public place in a short time off the zero line the case, do not worry about burning out light bulbs and appliances. .<BR> <BR> In addition, in the next public zero-line, be sure to bolt clamping, but also because the temperature change also affects the wiring of the thermal expansion and contraction. .Thus, even a few months later to tighten a bolt. .<BR> <BR> Final point is to love light it can show her side of it fascinating. <BR> <BR>.
