UV LED Curing System Advantages
UV LED curing systems is cold LED-UV light source , which is more healthy and eco-friendly for environment with UV LED curing system advantages. UV LED lamps is without heat radiation when curing. The surface temperature of the illuminated items is low , to solve long-term thermal injury in optical communication and liquid crystal production , especially suitable for occasions such as liquid crystal sealing , thin film printing and so on Small heat could solve the unbearable problem of staff because of the large amount of heat by mercury lamp printing equipment . On the other hand , LED-UV light source is a single-band high-purity ultraviolet light , and it is almost without any infrared light emitting . It is cold light source , the workpiece will not be deformed by heat.
High efficiency : LED-UV light energy is highly concentrated in the effective curing of a UV spectrum to shorten curing time , its practical effects and intensity is similar with 1000-2000mW / cm2 conventional high pressure mercury lamps curing effect . The conventional mercury lamps UV light looks high brightness , but the heat is high . Because it is very wide spectrum , the real effective curing of the UV spectrum is only part of the energy . There is a considerable part in the visible light ( clutter ) and infrared spectrum ( resulting in heat generation ) It is easily to cause the damage for the operator' s eyes and to make the curing project to get deformed.
LED UV Technical Requirement for Offset Press Printing
1 . Cold light source , no heat radiation , suitable for the bonding of heat-sensitive materials
2 . Small size is able to get the device be easily integrated into the automatic production lines and equipment
3 . Without any preheating period , their irradiation intensity could be up to 500mw / cm2-12000mw / c m
4 . UV LED doesn t have infrared radiation no harmful gases . Compared to the traditional mercury lamp it is more safe and environmentally friendly
5 . Lifespan is more than 20,000 hours so as to reduce labor cost and maintenance cost
UV curing will have more and more UVLED fans in the very near future.
