Efficient Generation of UV Radiations

There are a lot of UV sources commercially available that can be used for curing.Depending on theprinting and exposure application, different UV lamps are needed to adaptspectral distribution,process speed, thickness of the material to be cured etc. UVlamps are produced with lengths varyingbetween a few centimeters and four meters, specific electrical power between 0.1W/cm and 400W/cm, spectral emission from the deep VUV up to the long-wave UV-A, radiant efficiencesbetween afew percent up to 60% and lifetimes of some hundred hours and of some thousandsof hours.
