【 Weak current College 】 lighting control norms and techniques

As the saying goes, there is no rule hard to achieved by. Therefore, in the manipulation of light, there can be any arbitrary because lighting control has its own practices and skills, otherwise, would cause the light bulbs, lighting, lights, dials, damage, or even cause fire, causing serious damage. Below is from practical work summarizes the taboo and light manipulation techniques, hope to be helpful.
The following is the actual work is often the mistake operation, point out that lesson.

1. in the light bulb cold state, suddenly pushed off (full) lighting, results may cause the bulb to "snap" of a sound-blasting pieces; or cause a bulb tungsten wire fuse.

(1) because the bulbs in the production process, the lamp glass shell thickness unevenness inevitable and therefore lead to heated unevenness of the phenomenon. When suddenly pushed off the lamp, causing the lamp glass shell instant heating up, as if life to an empty glass filled with boiling water the same effect.

(2) after you are finished using the light, the light bulb in the hot-cold, will absorb the water molecules in the air, the water molecules will stay on the bulb on the aggregation of glass shell. When you suddenly pushed off the bulb, the glass shell of water molecules, as if boiling cream in water-like effect, bulb shards is logical.

(3) suddenly pushed bright lights can cause momentary impulse current (high) so easy tungsten wire stripping off the bulb.

Operational skills: when the lamp in the cold state (warm-up before), the control bench pusher of faders only some (often said by calendering) lamp-lit, so to keep them in a warm, making it heated evenly, while evaporated condensation in bulb glass shells of water molecules, preheating after a few minutes, then push off, then warm up after a few minutes before the light fully pushed off.

2. avoid the dimming platform faders to push full, then turn on the power of Silicon case. The result is the same as the above results, and the two damaged bulbs. Should be dimming platform all faders is off, the line open Silicon case power supply.

3. avoid in switching equipment, light control console and Silicon case power supply out of order. Turn on the power, the first open lamp control console's power, then turn on the power of Silicon case; turn off the power, turn off the power of Silicon case, turn off lights and control console. If you reverse the order of operations, will cause all rows are blinking lights, this will affect the life of the lamp.

4. do not push the light bulb, the big move shake lights. Bulb tungsten peeling will therefore fracture or.

Bulbs in the lights, the temperature gradually rise, tungsten accordingly will become soft, while under the influence of gravity, tungsten wire blepharoptosis accordingly (if the lamp does not use screw-shaped tungsten, this phenomenon is particularly evident), when the big rocking lamps, also have to wait until the light be cooled before demolition.

5. do not replace the bulb, bulb direct contact with hands, which affect the bulb finish, while another hidden hazards is led bulb of shards.

(1) finger of grease or fingers and bulb glass surface friction will stay "scars", thus affecting the bulb finish and transparency therefore affected the normal illumination of the lamp.

(2) If a sweat on her finger, fingers and bulb "intimate" contact, sweat in salt molecules will absorb the water molecules in the air, and once the water on the bulb when the bulb when the rapid warming, it is easier to burst.

Action Tip: when replacing the lamp, be sure to wear gloves, then go to the contact with the bulb. If you do not have gloves, available package lamp by sponge, plastic paper or soft tissue, and then make install, the installation must remember these wrappers down so as not to push the light bulb is the fire.

6. avoid the back light rays from the light speed is too focused. Too much focus is within a short period of time will be installed in front of coloured paper color fading, lose color, moreover, will always add roasted with burning a hole. If the direct distance between the lamps and flammable substances near, not likely be point.
Action Tip: adjusting the lamp radiation beam, tuned slightly astigmatism is better, if it is not enough you can supplement the luminance in the luminaire.

7. don't put the color change at the same time forgot to install protective net mask, protective netting to prevent light bulb when splash wounding and burns article

Like the back light is not on the 2 retaining pendant grooves on the inside of a file is packed with protective netting, while outside a block is loaded for use of color, PAR lamps have a fixed protective NET cover, this is not very good?

8. remember the hot light source lamp and inflammable screen distance too "intimacy". Years ago, the northeastern one school at a time during the performance, because the light will be lit a fire caused by a curtain, causing hundreds of casualties of the tragedy. Therefore, lights and curtains, and maintain a certain distance between is by importance. 300W lamps direct direction and distance of the curtain shall not be less than the side 3cm, lamps, tail and curtain (rest) of distance shall be not less than 2m, if screen swing of widely, it is possible to lighting, the best in lighting and curtains in the middle of a metal separate mesh to prevent the curtain on lamps and cause a fire. 500W lamp above, direct screen distance in 5m, side, rear and screen outside of distance in 3m.

9. avoid the installation of lighting and power over the power required by manufacturers. Lighting Silicon case for each circuit hosted by a power in the manual there are detailed instructions. Generally each circuit, hosting a 1KW power 2KW, 3KW, 6KW. Respect to 6KW, for example, Silicon inside the SCR is also called solid state relay 60A, calculations, can host power is 13. 2KW, anyway there is so much power in space, in this circuit can be installed on more lights 6KW. The author believes that only considers the bulb in fuse the current moment, like the problem is one-sided. Besides the manufacturers will not winNo reason to leave such a power of SCR, this is some truth in it.
