Experience shows that the useful life of a lamp is between 1000 and 3000 hours.
To maximize the life of the lamps is necessary verify the system of ventilation, a non-polluting environment and the qualification of operators.
Some of the recommendations to help you to increase the life of your lamps:
-Avoid excessive starts: the lamps should be started at full power in order to reduce the start-up period. Excessive starts cause premature darkening of the ends, this will result in a drop in output as the darkening eventually migrates into the body of the lamp. To avoid these situations, whenever possible, gather all of the work to be done, start the lamp and perform all of the work that can be done during this time.
-Check the lamps, reflectors and ventilation system: curing often fails due to poor lamp and system maintenance. Preventative maintenance is extremely important to minimize the problems in processes with UV technology. In order to increase the working life of lamps as well as the entire cure system it is advisable every 500 hours of operation, perform the following steps:
1-clean the lamp regularly to remove any dust, preventing devitrification problems. Lamps should always be handled using gloves and cleaned with isopropanol.
2-the reflectors have a function of improving efficiency of the system. Check if the reflectors are clean and free of distortion from the lamp’s radiated heat. Periodic cleaning and/or replacement of reflectors may be necessary to maintain maximum efficiency of both the lamp and equipment.
3-check the ventilation system: the accumulated dirt in the ventilation blocks causes the system to stop making the cooling necessary for proper functioning, causing overheating in the lamps and consequently a drop in voltage and power. The cleaning of the power supply system and air filters is essential.
4-Minimizing the risk of deformation: UV lamps generate much heat, so it is not uncommon deformations occur in the tubes, this phenomenon reduces the lifetime and efficiency. To minimize this risk, it is recommended to periodically run the lamps in 1/4 turn. Never directly touch the hot and even cold lamp, always use clean rubber gloves or cotton.
-Install Lamps with Care: avoid direct hand contact with the lamp tube. For handling use gloves or a paper towel. The use of an alcohol wipe is also recommended to assure clean surfaces. Important to ensure that the electrical connections are tight and not corroded.
