UV led wavelength
UV LED lights have a narrow spectral output centered around a specific wavelength, +/- 10nm. Phoseon’s products primarily utilize use 395nm wavelength. However, since they are a solid state device, they can be built with other wavelength diodes, of which 365nm, 385nm, 405nm, 410nm, are the most popular. This monochromatic distribution (see chart) requires new chemical formulations to ensure proper curing of inks, coatings, and adhesives. Request more informationUV LED Vs. Mercury Spectral Distribution
The majority of UV curing happens in a narrow emission range with the remainder of the spectral output generating unneeded and potentially harmful UV-C and infrared emissions. UV LED lights provide this narrow emission range.
UV LED curing lamps efficiently convert 15-30% of the input electrical power into usable UV light with no harmful UV-C or infrared exposure. That efficiency translates into approximately 80% power and heat savings over mercury based lamps.
