UV curing equipment has also undergone continuous research and development and improvement process. The main production technology of mercury lamp irradiation has been used for a long time. However, due to the high cost of equipment, high maintenance costs, fast attenuation of UV light intensity, the surface temperature of irradiated components, large volume, expensive consumables, tribute pollution and other defects, the industry has been committed to improving, but because of the limitations of the original hardware has been difficult to break through.

 

 

 

The advent of UV LED has brought revolutionary changes to the UV curing industry. It has the characteristics of constant illumination intensity, excellent temperature control, portable and environmental protection, relatively low procurement cost and almost zero maintenance cost, which promotes the quality improvement and energy saving of UV curing process.

 

 

 

UV LED point light source, linear light source and surface light source have been applied in various industries.

 

 

 

Long service life of UV LED light source

 

 

 

Compared with traditional UV curing equipment, the service life of mercury lamp is only 800-3000 hours, and the service life of UV-LED UV curing system reaches 20000-30000 hours. LED mode can be lit only when ultraviolet light is needed. When DUIY = 1/5 (preparation time = 5 irradiation time = 1), the service life of LED mode is 30-40 times as long as that of mercury lamp mode. It reduces the time of replacing the bulb: it improves the production efficiency, but also saves energy. When the traditional mercury lamp curing equipment works, because the slow start and close of the mercury lamp affect the lamp life, it must always be lit, which not only causes unnecessary power consumption, but also shortens the working life of the mercury lamp.

 

 

 

No thermal radiation when illuminated by UV LED light source

 

 

 

High power light emitting diodes do not emit infrared light. The surface temperature of the irradiated product rises below 5 C, while the traditional mercury lamp ultraviolet curing machine will generally raise the surface of the irradiated product by 60 - 90 C, which will displace the positioning of the product, resulting in bad product. UV-LED curing method is most suitable for thermal sensitive and high precision bonding process requirements of plastic substrates, lens bonding and electronic products, optical fibers and cables.

 

 

 

Environmental Protection and Pollution-Free Ultraviolet LED Light Source

 

 

 

The traditional mercury lamp curing machine adopts mercury lamp luminous mode. There is mercury in the lamp. It is very troublesome to dispose and transport waste products. Improper disposal will cause serious pollution to the environment. The LED curing machine uses semiconductor to emit light, and there is no pollution to the environment. Therefore, the use of LED curing machine is more environmentally friendly.

 

 

 

UVLED Light Source with Super Illumination

 

 

 

Using high power LED chip and special optical design, the ultraviolet light can achieve high precision and high intensity irradiation, and the ultraviolet light output can reach 8600 mW/m2 irradiation intensity. By using the latest optical technology and manufacturing technology, the high strength output and uniformity are more optimized than the traditional mercury lamp irradiation mode, which is almost twice the irradiation intensity of the traditional mercury lamp mode. The UV adhesives are cured faster, the production time is shortened, and the production efficiency is greatly improved.

 

 

 

When the traditional mercury lamp point light curing machine increases the irradiation channel, the output energy of a single irradiation channel decreases with the increase of the channel. Using LED irradiation, each irradiator emits light independently, and the irradiation energy is not affected by the increase of channel, and always maintains the maximum value.

 

 

 

Compared with mercury lamp, UV LED shortens the irradiation time and improves the production efficiency because of its super concentrated illumination.

 

 

 

Low Energy Consumption for Ultraviolet LED Light Source

 

 

 

The effective luminous efficiency of UV-LED is more than 10 times higher than that of mercury lamp.
