Characteristics

It contains LED emitters that only emit one wavelength, where a strong light is placed where the energy is located in the range necessary to activate the photo initiators without accusing the disadvantages of useless radiation of other wavelengths. Infrared radiation radically conditions the use of halogen lamp systems in machines or close to people.

These characteristics make them highly efficient systems, since with 20 W of power they are more efficient than a kW halogen equipment. The graph below sums it up.

If we look at the graph of a halogen UV lamp and see that the active wavelengths in most inks are close to 400 nm. See the small area identified as ultraviolet, all the rest of the emission of visible light and infrared light is useless and not necessary in the curing of inks.
