Advancements and Challenges in UV LED Curing Systems

The UV LED curing system is increasingly used in various industrial curing applications, thanks to the continuous advancement of the technology and the maturation of cooperation between industries.

The core technology of UV LED curing includes not only UV coatings, ink materials and formulation techniques, but also the curing systems that complement each other.

While UV coatings and ink formulation techniques for mercury lamps have evolved significantly over the years and are relatively mature, the transition to LED UV light sources presents some technical challenges that require further research and resolution.

Currently, there is an urgent need to address the following three major issues:

  • Efficient, non-yellowing, and economical photoinitiators that match the UVA spectrum.
  • Low-migration coatings and inks suitable for food packaging and compliant with standards.
  • UV coatings that rival the adhesion and other physical properties of thermally cured coatings.

The UV LED system mainly consists of lamps, cooling systems, and drive control systems, making it a knowledge-intensive product involving many disciplines such as optics and packaging, cooling, heat transfer, power electronics, and others. Deficiencies in any one of these areas can greatly affect the quality and overall performance of the product.

As a result, the successful development of UV LED systems typically requires talents such as structural engineers, heat transfer and fluid mechanics engineers, optical design engineers, software engineers, power electronics engineers, and electrical engineers.

The main difference between the UV LED industry and the traditional mercury lamp industry is that UV LED is a semiconductor product and its technological development is extremely rapid. It requires continuous investment in research and development to keep up with technological trends or risk being quickly phased out of the market.

By utilizing a multidisciplinary approach and drawing on the expertise of professionals in the fields of optics, heat transfer and power electronics, UVET company ensures the development of robust and reliable UV LED curing lamps. UVET is committed to continuous research and development in order to keep pace with the rapid development of the industry.
