uv led curing productsUV LED technology is rapidly replacing traditional mercury or arc based lights for the reasons outlined below. The change from conventional curing technologies to UV LED allows system manufacturers to offer their users lower operating costs and higher quality products while enabling new capabilities and even reduced shipping and inventory storage due to the ability to print on thinner, heat-sensitive substrates.

UV LED Vs. Mercury Arc Lamps
Traditional UV lamps produce light by generating an electric arc inside an ionized gas (typically mercury) chamber to excite atoms, which then decay, emitting photons. The photons cover a broad range of spectrum of which only about 20% is useful for UV curing.
UV LED solutions produce light by generating a voltage across a solid state semiconductors device to join positive holes with negative electrons emitting energy in the form of photons.
Combining energy generation of today’s UV LED light sources and the right formulation of UV curable resins, photoinitiators, and additives, it is possible to surpass current process capabilities for a variety of applications. Phoseon has worked with a large number of third party formulators to develop materials specifically formulated for UV LED technology.
