Presentation: Designing a UV LED curing system for wire, cable and optical fiber applications

For the past 40 years, optical fiber manufacturing has advanced with the benefits of UV curable coatings, inks and matrix materials. Using  medium pressure, mercury-based UV lamps the industry has profited from high speed coating processes (up to 2400m/min), decreased downtime, reduced waste and high quality, durable products. These lamps systems were specifically designed to meet the exacting demands of the optical fiber coating process.

More recently, there has been a shift to look at UV LED lamps as the curing system in these processes. UV LED lamps have environmental and energy saving benefits but they must also deliver uniform, focused, high irradiance UV energy needed to polymerize the coatings at a fast speed with high reliability. That required an innovative UV LED lamp system design.

The presentation will describe the challenges and solutions in designing a  UV LED lamp system to deliver high power, high irradiance, reliable UV for use in demanding optical fiber coating manufacturing processes. In addition, it is envisioned that this UV LED lamp system design could also be used in similar manufacturing processes such as thread, wire and cable coating.
