Computer lamps and lanterns is a kind of important lamps. In the entertainment activities plays an atmosphere, rendering the stage of artistic conception, mobilize the emotional role, so it is widely used. Guangzhou stage lighting
Computer lamp is a kind of more sophisticated equipment, it sets the electronic, mechanical, optical equal to one, the environment, transportation, use and other requirements, and therefore its failure rate is higher. Here the failure phenomenon, the possible reasons for the analysis, for reference.
Boot no response
1, the power supply is normal, the lamp power supply line is off;
2, the lamp tube has not burned out insurance;
3, lamps and lanterns of the switching power supply output voltage.
Start up without light
1, first determine the lighting is good or bad, the lighting in a spherical polar distance is too long, whether there is leakage (glass in a piece of milk white), and view the lighting is loose.
2, determine the lamp in the state of the bubble is in the state, the measurement of the main board is the output of the voltage is normal, the normal situation is generally 12 ~ 10 v.
3, if the above two points without error, measurement of the electronic ballast point bubble instant there is no about 380V AC voltage output, if there is output, Guangzhou stage lights show that the ballast is good, so that it can be directly identified as a problem.
After a period of time, the lamp automatically reset
1, switching power supply output voltage instability;
No loosening or pressing cable line 2, line, resulting in poor contact, thus automatically reset.
Bulb automatic bubble
1, lighting destroy bubble, over time and automatic light bulbs, check cooling system is working properly, if the cooling system failure, will lead to the lamp body temperature is too high, the temperature control switch can automatic tripping. In order to ensure the safety of lamps and lanterns. In the case of electronic lighting lamp is closed, when the lamp body temperature is reduced, and will automatically light up.
2, light bulb after the bubble, can not automatically light bulb: light bulb's own problems, bulb surface is white, the interior is black, light bulb for a period of time after the phenomenon of the phenomenon (bulb life end).
There will be destroyed, no 3 gun automatic protection lamp control signal in the case of long time, will automatically switch on signal lamp.
The pattern plate, the color disc, the prism, the focusing, the enlargement appear card dies, the jitter, the step loss
1, the card is dead for mechanical reasons (except CMY), when a piece of CMY chip, so that it falls off, so as to affect the normal operation of other colors, this time there will be the phenomenon of the death of the card, such as pattern plate, color plate deformation, fixed part of the screw loose fall off, fixed pattern of the pressure spring pop and other reasons, will lead to the case of card.
2, jitter and loss step: screw loose or fall off, the channel on the motherboard chip burned, the motor line contact undesirable, broken skin on the short circuit, the motor itself.
Horizontal vertical (X/Y axis) step, not positioning
Too much dust, 1 coupling, resulting in infrared light can not control in place;
2, optocoupler board is damaged, the distance between the optical disc and optical regulating improper (excluded, should do optocoupler plate in the middle of the optical disk, and do no scratch, touch, the phenomenon of inside).
These are some of the common causes of failure analysis, in fact, to reduce the occurrence of failures, maintenance and maintenance is essential, the following brief introduction of the daily maintenance of the need to pay attention to:
1, optical element, first of all with vacuum cleaner or blow air to surface dust blowing gently to, with no odor Mianzhi or leaching water of cotton cloth to wipe to particulate matter, soaked in ethyl alcohol cotton or odorless paper to remove dust and residue, with distilled water and do a final cleaning, use a soft cotton cloth to wipe.
2, with a coating of color film, design and optical lens components, because the film is very brittle surface, it is easy to scratch, so do not use a destructive solvent cleaning;
3, to regularly replace the air filter cotton, so that it is in the best ventilation condition, and enhance the heat dissipation of the lamps;
4, computer lights tohandlegentlyand avoid collisions, falls, etc.;
5, do not pay attention to the use of dust in the dust on the occasion;
6, power supply voltage should be stable, long-term supply voltage in 240 volts to consider the use of power supply;
7, after the completion of the performance, with the console to destroy the bubble, the lamp does not cut off the power, the Guangzhou stage lights let it continue to work for a period of time (so that fans continue to work, to reduce the internal temperature of the lamp);
8, after the performance of the performance, to load the special air box in the moisture and shock, fixed installation of computer lights should pay attention to prevent the dust, anti impact, etc..
