Compared with traditional UV mercury lamps, UVLED UV light sources have the characteristics of long service life, soft light output, low energy consumption, safety and pollution-free, wide irradiation area, uniform light spot, and convenient installation. LED type UV surface light sources are used in Large-area light curing, such as microelectronic devices, LCD, PCB, inkjet printing, mobile phone surface treatment, etc., replaces traditional large high-pressure mercury lamps, which consume less energy, last longer, and significantly reduce maintenance and use costs.
The traditional mercury lamp method has a large power and a small heat dissipation area. Even if a large number of radiators are added, a large amount of heat cannot be quickly led out, which accelerates the attenuation rate of light and has a service life of only 1000-3000 hours. The heat dissipation effect of the UVLED light source with the same power is dozens of times of the mercury lamp, and the life can reach 25,000-30000 hours, and the life can be achieved by controlling the lighting. The traditional mercury lamp method has high power consumption, high frequency of lamp updating, and requires UV fiber output, which greatly increases maintenance costs. UVLEDs have low energy consumption, and the luminous efficiency is more than 10 times that of mercury lamps. There is no lamp replacement. Low maintenance costs. UVLED high-power diodes do not emit infrared light, and the surface temperature of the irradiated product is below 5 ° C. The traditional mercury lamp method will increase the surface temperature of the irradiated product by 60-90 ° C, which will cause the positioning of the product to be misaligned, thereby improving The defective rate of the product.
The volume of the UVLED controller is about 1/8 of the volume of the traditional mercury lamp irradiation machine, which makes the installation of the equipment simpler and reduces the area occupied by the production site. The irradiation head fully considers the space requirements of precision production to make the installation of the device more convenient. In addition, the small head uses a fan heat dissipation design to fully guarantee the energy stability and service life of the LED for a long time.
