UV LED curing products offer advanced capabilities, operating economics and environmental advantages. UV LED curing allows system manufacturers to offer their users lower operating costs and longer-lasting solutions while enabling new capabilities and even reduced shipping and inventory storage due to the ability to print on thinner, heat-sensitive substrates.
UV LED solutions produce light by generating a voltage to join positive holes with negative electrons emitting energy in the form of photons. These semiconductor devices are designed to last beyond 20,000 of operating time, unlike traditional UV lamps that produce light by generating an electric arc inside an ionized gas (typically mercury) chamber to excite atoms, which then decay, emitting photons. Additionally, the European Commission (EC) through its Restriction on Hazardous Substances (RoHS) guidelines has continually monitored the rapid progress of UV LED's capability. Many in the industry predict the EC will begin limiting traditional lamp usage, starting first with smaller systems then working towards larger systems in ensuing years.
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.
