Basics of LED UV technology

The technology, with which inks, varnishes, silicones and adhesive are cured using UV light, has plenty to offer the printing and coating industry. Since the start of this millennium, LEDs have been used in addition to arc lamps for UV curing.

Measurement technology

The output of a UV lamp is measured in W/cm. It describes the electrical input, i.e. the electrical power input per centimetre of lamp length. The output of a UV LED, however, is given in W/cm². This represents the optical output, i.e. the light output per square centimetre.
