UV, Ultraviolet is the full name, namely ultraviolet rays. UV LED is the emitting diodes emits UV light. Ultraviolet (UV) is invisible, is visible for some electromagnetic radiation violet light outside the range of 10 ~ 400nm. UV LED as a branch of LED, although not directly used for lighting, but with all the advantages of LED, in theory, can replace all traditional UV light source, greatly expanded the LED applications. Today, UV LED market has increasingly been adopted, it has become the new darling of the LED business.

Compared with traditional mercury UV LED in terms of energy saving, environmental protection, low voltage safety, small size, on and off any time, long life, low temperature, but the disadvantage is the relatively high cost of the initial investment. The main advantage of UV LED is as follows:

(1) Energy efficient: UV LED light intensity per unit area of ??more than 1000 times more mercury. For example, a single LED light emitting area of ??only 0.3 mm 脳 0.3mm, but the light power is greater than 1mW, while the optical power in the mercury emitted from such a small area of ??less than 1 mw. High energy UV LED light output stability, good illumination uniformity effect. UV LED can be customized effective radiation area, length from 20mm to 1000mm. UV LED instant light, no warm-up instantly reach 100% power UV output. The same optical output power, UV LED energy is only 1/10 of mercury.

(2) Safety and environmental protection: UV LED does not contain mercury, it does not produce ozone, non-toxic, can replace traditional light source technology a safer, more environmentally friendly choice. Mercury inkjet equipment heat, staff unbearable, and UV LED cold light source, no heat radiation, according to the product surface temperature is low, heat a small, solve the optical communications, heat LCD production long-standing injury problems, especially for liquid crystal Edge, film printing and other requirements temperature rise occasions.

(3) Reliable and durable: reflected in the switching characteristics and the useful life of intelligent control. Since the light emission characteristics of the LED, no pulse switching any effect on the life of LED, 6V DC sync emits ultraviolet light is turned on, and the mercury switch directly affect their life, as compared with conventional mercury lamps, LED's UV issue and control is extremely simple and convenient. UV LED life is more than 10 times that of traditional mercury type curing machine, about 25000-30000 hours. UV LED maintenance cost is almost zero, the use of UV LED curing equipment annual savings of at least 10,000RMB/ station supplies fee.
