In the process of lighting control and operation, there are often many unexpected situations. The following are some specific problems that are commonly seen in actual operation -- symptomatic treatment.
1. When the bulb is cold, suddenly push the light on (full), which may cause the bulb to crack.Or cause the bulb tungsten wire to fuse.
(1) in the production process of the bulb, the glass shell of the bulb inevitably has uneven thickness and thickness, thus leading to uneven heating.When the bulb is suddenly turned on, it will cause the glass shell of the bulb to heat up instantly, just as life fills an empty glass with boiling water.
(2) after using the light, the bulb will absorb water molecules in the air in the process of changing from heat to cold. These water molecules will stay on the glass shell of the bulb and accumulate.When you suddenly push the light bulb on, the water molecules on the glass shell will act as if they were pouring water into a hot oil pan.
(3) a sudden push to turn on the light will cause an instant shock current, which will easily dissolve the tungsten filament of the bulb.
Skills: when the light bulb in the cold state (former) before the opening, the console of the pusher push up only a little (often said that the pressure of light), make the lights dim, let it at preheating condition, make its heated evenly, and evaporate condensation of water molecules in the bulb of glass shell, preheat for a few minutes later, another brighter, preheating again after a few minutes, before pushing light fully bright.
2. Do not turn on the power of the silicon box again when the dimmer push the push button full.The result is the same as above, both of which can damage the bulb.All promoters of the dimmer should be turned off to turn on the power of the silicon box.
3. Do not reverse the order of the power supply of the lamp console and the silicon box when switching the equipment.When turning on the power, first turn on the power of the lamp control desk, and then turn on the power of the silicon box.When power off, first turn off the power of the silicon box, and then turn off the power of the lamp console.If you reverse the order of operation, it will cause all the lights to flicker, which will affect the service life of the bulb.
4. Do not shake the lamp when the bulb is pushed on.The tungsten filament of the bulb will break or fall off.
Skills: after the light bulb, the temperature gradually raised, tungsten wire is correspondingly will become soft, at the same time under the influence of gravity, tungsten correspondingly prolapse (if not adopts screw shape tungsten filament bulbs, this phenomenon is particularly obvious), while big shake when lamps and lanterns, lighting should wait until completely cooled, can remove.
5. Don't touch the bulb directly with your hands when replacing it, which will affect the lightness of the bulb. Another hidden hazard is the explosion of the bulb.
(1) the grease on the finger or the friction between the finger and the glass surface of the light bulb will leave a "scar", which will affect the cleanliness and transparency of the light bulb, thus affecting the normal illumination of the light bulb.
(2) if there is sweat on her finger, finger and bulb "intimate contact", the salt in the sweat can absorb water molecules in the air, once there is water on the light bulb, rose sharply when the light bulb, it is easy to crush.
Operation skill: when changing the bulb, you must first put on gloves and then touch the bulb.Without gloves, available packing light bulb of the sponge, soft plastic or paper towel, and then to install, after installation must remember wrap these things down, so as to avoid fire when push the light bulb.
6. Do not overfocus the light speed of the reflector lamp.Too much focus will make the colored paper on the lamp lighter and lose color in a short time, or even burn a hole in the paper.If the luminaire is too close to the flammable material, it is impossible to spot it.
Operation skill: when adjusting the light beam of the lamp, it is good to make it slightly astigmatized. If the light is not enough, the lamp can be supplemented.
7. Do not forget to install the screen cover when installing the color changer. The screen cover is to prevent the explosion of the bulb from splashing people and burning objects.
Like no 2 on the back light hang groove, on fence cover with a is installed inside, and outside color change for a block is installed, some PAR lamps and lanterns has fixed shield cover, it would be nice?
8. Remember to make the lamps and lanterns of the thermal light too "warm" from the flammable curtain.A few years ago, a school in the northeast of China set fire to a curtain lit by lights during a performance that killed and injured hundreds of people.
Operational skills: to avoid fire hazards, lighting and curtain to maintain a certain distance between the important light.300 w the direction of direct distance with the curtain of lamps and lanterns shall not be less than 3 cm, lamps and lanterns of the side, the tail and the curtain (static) shall not be less than 2 m, if the curtain oscillation amplitude is very big, it is possible to close to the lamps and lanterns, in the middle of the curtain lamps and lanterns and set up a best metal cars, to prevent the curtain on the lamps and lanterns and fire.For luminaires over 500W, the distance of the direct curtain is more than 5m, and the distance of the side, tail and curtain is more than 3m.
9. By all means, the power of installed lights shall exceed the power specified by the manufacturer.The power carried by each circuit on the lamp silicon box is specified in the specification.Generally, the load power of each circuit is 1KW, 2KW, 3KW and 6KW.Is 6 KW, for example, silicon in silicon controlled rectifier and solid state relay is a 60, calculate, carry power is 13.2 KW, anyway have so much power space, in this time can be installed more than 6 KW lights on the road.It is one-sided to consider only the current produced by the bulb at the moment it is fused.
10. Do not cause three-phase imbalance when connecting the load.As you know, the power input from the lamp silicon box is mostly three-phase four-wire system.When the lamp load is connected to the silicon box, if it is not distributed, the lamp load is connected blindly, which may lead to the phenomenon of three-phase imbalance.So, when the light is turned on, you can feel the difference between light and dark.
