New Webinar: Lens Material Selection for Exterior Aircraft Lighting

New Webinar: Lens Material Selection for Exterior Aircraft Lighting

When designing an exterior aircraft lighting fixture, it is necessary to choose a cover lens material that is resistant to pressure, abrasion, and impact.  With the onset of LED technology, manufacturers of lighting fixtures essentially have two options for cover lens materials: glass or plastic. This decision affects safety, maintenance, and total cost of ownership.…

New White Paper Demonstrates How Abrasion Resistant Lenses Lower Maintenance Costs

Kopp Glass

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. In the aerospace industry, Light Emitting Diode (LED) technology promises to keep planes operating longer with reduced maintenance costs and lower power consumption. With…

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…
