MOLDED UV OPTICS FOR INDUSTRIAL UV LED CURING

Glass for Industrial Equipment Applications

 

The industrial curing market is rapidly evolving with the introduction of UV LEDs. They offer many benefits compared to mercury vapor sources, but there are still many challenges that need to be addressed before widespread adoption is realized, including high costs, availability of commercially viable UV-C LEDS, formulation compatibility, and working distance limitations.

To help you harness their benefits and create fully optimized UV LED lights, we offer custom molded UV optics that increase UV LED irradiance and improve light distribution uniformity. Our molded UV optics enable the creation of high-performance UV curing lights that enable flexible working distances and the ability to cure both flat and complex 3D surfaces. Achieve greater design freedom while also improving energy efficiency, using fewer UV LEDs, and improving overall thermal management.

HIGH-PERFORMANCE LIGHTS ENABLE VERSATILE, EFFICIENT CURING SYSTEMS

High-performance UV lights help you create versatile curing systems with flexible working distances that are ideal for both flat and 3D surfaces. This enables you to achieve better quality while increasing throughput, improving energy efficiency, and extending the useful life of the UV LEDs.

Maximize Irradiance and Increase Working Distances

Molded UV glass optics increase the energy density hitting the cure surface and enable greater flexibility in cure system working distances. Maximizing the irradiance means you can cure complex 3D surfaces and ensure that the light is evenly distributed onto the surface.

High-performance Lights with Fewer UV LEDs

When first transitioning to UV LEDs one of the biggest barriers to overcome is their high cost. In high-performance flood curing units, it’s essential to maximize irradiance uniformity over large areas, which often requires large numbers of UV LEDs.

Our solution reduces the initial investment required; optics increase irradiance and allow you to reduce the number of UV LEDs in the unit, while still achieving the desired energy density.

Increase Productivity While Maintaining High Cure Quality

An increase in irradiance can boost performance of the entire curing operation. With greater energy density reaching the surface, you can increase line speeds and shorten processing times. UV optics improve irradiance uniformity and ensure that even at faster speeds, you still achieve a uniform cure.

Reduce Thermal Management Requirements and Extend UV LED Useful Life

The key to increasing the useful life of an UV LED is proper thermal management. In high-energy applications, UV LEDs require rapid heat extraction; otherwise, an increase in junction temperature will cause the UV LED to degrade over time.

The use of an optic allows you to reduce the number of UV LEDs required or to reduce the drive current to the UV LEDs. Both of these options give you the light intensity you need, while reducing the requirements for cumbersome cooling systems. Use optics to improve energy efficiency, decrease the thermal management requirements, and extend the useful life of the UV LEDs.
