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

Custom molded UV glass optics

Maximizing a UV LED’s peak irradiance is imperative in many UV curing applications. More power can improve production speeds and increase throughput. In these applications, 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. We wondered, is…

Chromaticity Basics: Factors, Calculation, and Application

Chromaticity Basics, Calculations, Factors, and Applications

Color is a universal language. At traffic lights around the world, drivers understand to stop on red and go on green. For many signaling applications, including those in the railroad and aerospace industry, operators are trained to recognize and respond to very specific colors. So how do you make sure that your light fixture outputs…

A Year of Light: Notable Light-based Research and Technologies in 2015

2015 Year of Light

Looking back on 2015, it was a significant year for the lighting and photonics community; it was the year that the world celebrated light. Launched at the start of 2015, the International Year of Light (IYL) was a celebration of light and light-based technologies across the world. One of the main objectives of the IYL…

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

How to Design with LEDs

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

LED Useful Life

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…
