UV-LED Lamps: A Viable Alternative for UV InkJet Applications

摘要

The power, cost and capability of ultraviolet light-emitting diode (UV-LED) lamp systems have improved to the point where they now represent a viable alternative to traditional mercury-vapor lamp curing technologies within several inkjet applications. This article will identify the advantages of the LED-based technology, as well as the engineering challenges involved in transitioning from a traditional, mercury-vapor curing system. This article will also identify some critical performance criteria that should be used when evaluating UV-LED systems.
