What the Characteristics of UV LED Light Performance are 2018-08-31 16:18:29

1.UV LED safety and environmental protection standard VU varnish belongs ti solvent-free varnish with 100% solid content. In other words, all light enters the film in terms of effective film, VOC emissions, helping to prevent air pollution, improving the operating environment, and reducing fire risk.

2.High production efficiency, fast curing, higher than the general polishing method, the current curing speed is 50-150 m/min, up to 300-500 m/min.

3.Suitable for a wide range of UV LED polishing paper, as well as a large number of substrate such as aluminum foil, gold and silver cardboard, vacuum aluminum, laser film, plastics, synthetic paper, metal, wood and other printing carriers.

4.Excellent film forming performance UV LED glass is not only of high gloss and smoothness. After UV curing, due to the formation of the tough network structure of the body, it has excellent abrasion resistance, water resistance, heat resistance scratch, chemical resistance and solvent resistance.

5.The UV LED energy saving and floor area of UV LED polishing equipment covers a much smaller area than the dry tunnel area uses much more energy, making it ideal for online polishing and automated assembly line operations. Because VU polishing performance is stable, does not contain volatile solvent, not easy to cause the viscosity change of coating process, so coating stability is good, time saving.

6.In order to avoid the resin used in solvent coatings, it is mainly thermoplastics resin. Due to temperature, humidity, coating thickness and drying conditions and other factors, UV LED can easily cause the degree of product adhesion, as well as the photo-curable coating. Only if the conditions area met, then don’t worry about adhesion problems, after polishing can be ant stack or post-processing operation.

7.UV LED can replace plastics and plastics film, and composite UC LED coating composite technology has been widely used in many communities at home and abroad. It completely avoids the frequent occurrence of Alice, bubbling, wrinkling, layering, and so on in the coating process, and can recycle paper, reducing the formation of environmental pollution that the film cannot regenerate.


UV LED is widely used in daily life. In peacetime, there are three factors that affect the life of UV LED lights :

1.Wall load.

2.Working voltage.

3.Power density.


The quality of quartz glass has a great influence on lighting. High quality quartz glass has high purity, no bubble inside, smooth surface. Because the temperature is usually on the wall above 600℃, if not enough material purity, can have a glass surface gasification, lead to many small pits, affect the radiation of ultraviolet from wall. The formation of the quartz eye can directly see the bubble inside the wall, the effect of ultraviolet ray on the wall, the high-temperature bubble forms the high-pressure air mass to break the wall. The UV LED electrode material is usually a barium zirconium or other cathode emitting material on the surface of tungsten filament. Tungsten and cathode materials, anti-aging, temperature directly affect the electrode life.


This factor is the most important factor that restricts the quality of household UV LED lamps. The main processes affecting the service life of the lamp are : cleaning the inner wall of the lamp, dust absorption, purity and injection amount of mercury, argon charging and discharging electrode lead welding, cathode material sintering, etc.. The whole process should be carried out in an advanced clean place. The sintering and welding of cathode materials should be done under vacuum conditions. At present, domestic manufacturers of UV LED lamps do not have these conditions, which greatly affect the lamp’s life. Improper use will greatly reduce the lamp’s life. Read the instructions carefully or consult with the supplier before using.
