Optimize UV LED Arrays For Efficiency and Performance

By Sharayah Follett | July 18, 2018

UV curing systems using UV LED arrays without an optical element frequently allow light rays to miss the curing surface. This wasted energy leads to increased operating costs. Conversely, an optimized system will direct the bulk of UV rays to the intended surface.

Abrasion Resistant Glass Lenses for Exterior Aircraft Lighting

New White Paper Demonstrates How Abrasion Resistant Lenses Lower Maintenance Costs

By Sharayah Follett | January 24, 2018

In this two-part study, Taber abrasion and high-velocity particulate impact testing are used to evaluate the suitability of borosilicate glass, polycarbonate, and aviation grade acrylic in exterior jet aircraft lighting applications.

Custom UV Glass Optics Increase Irradiance

New Study Shows that Custom UV Glass Optics Increase UV LED Irradiance by 25% Compared to Quartz Rods

By Sharayah Follett | July 14, 2016

Maximizing a UV LED’s peak irradiance is imperative in many UV curing applications. More power can improve production speeds and increase throughput. UV LEDs are often arranged into linear arrays, where they are placed side-by-side in a row, and are usually protected by a flat window or an optic.

How to Design with LEDs: Iterative Approach Yields Fully Optimized Lighting Systems

By Sharayah Follett | October 19, 2015

While the cost of light emitting diodes (LEDs) is decreasing, they are still relatively expensive and their adoption should be carefully considered before making the switch. Optimization of the optic and other system components can reduce the number of LEDs needed and reduce the overall cost of the LED lighting fixture. Solid state lighting (SSL)…

Challenges of Determining LED Useful Life

By Sharayah Follett | September 14, 2015

The transition to light emitting diodes (LEDs) from conventional light sources brings several new challenges to lighting engineers and designers. LEDs are much different than incandescent bulbs, especially in terms of useful life. It’s easy to determine the useful life of an incandescent lamp; if the light goes out, its useful life is over. This…

Combat Color Variability: Basics of LED Binning

By Sharayah Follett | June 30, 2015

Light emitting diodes (LEDs) or solid state lighting is infiltrating many lighting markets. The rapid pace of adoption and technology innovation leaves many engineers and designers struggling to understand the basics of LED technology and how it differs from traditional light sources. Before adopting LEDs, it’s important to have a thorough understanding of their mechanics, differences, and…
