LED Phosphor & Fluorescents Testing
State-of-the-art phosphor, fluorescence, and stress testing for developing the next generation of LED illumination
Did You Know?
- The output of LED lights has been doubling nearly every year since the 1960’s – today’s LED lights produce more than 300 lumens per watt.
- Isamu Akasaki and Hiroshi Amano won the Nobel Prize in 2014 for their invention of blue LED in the 1990s, finally enabling LEDs to produce white light we use today.
As the competitive LED lighting market continues to evolve at a rapid pace, the reliability of phosphors over time is a critical building block in making technical and operational progress. CSA Group offers some of the most advanced testing protocols for LED phosphors in the world, even creating our own tests and equipment where we see opportunities to serve you. We also have a robust High Irradiance Stress Testing program to ensure the safety and longevity of your LED luminaires. We can use our phosphor and high irradiance stress testing to evaluate your next product prototype or contribute to the development of your next breakthrough product.

As the global leader in LED testing, we invented a phosphor testing protocol that’s entirely independent of the LED – so our clients can create the best LED lighting products. We apply that type of innovation and passion to every service we offer.
White LED Phosphor Testing and Evaluation
Traditional testing systems for white light LEDs involve irradiating the phosphor with the LED for a long period. But the effects of aging on the LED itself can skew phosphor measurement. CSA Group developed our total fluorescence efficiency test specifically for the characterization of phosphor lens materials – completely independent of an LED. It’s the only testing protocol of its kind. With this unique dual-integrating sphere system, we test opaque, semi-transparent, or transparent sample LED phosphor materials for:
- Spectral reflectivity
- Spectral transmissivity
- Spectral absorbance
- Spectral fluorescence (forward, backward)
- Donaldson radiance factor (reflected, transmitted)
- Optical throughput (normalized)
High Irradiance Stress Testing
High-Irradiance Stress Testing is useful to manufacturers of SSL lighting components, including plastic lensing, phosphors, automotive, adhesives, and reflectors. CSA Group’s protocol utilizes our Elevated Temperature Irradiance Chamber (ETIC) to evaluate the deterioration of plastic samples and phosphors exposed to blue light irradiance and elevated temperatures. You can also request alternate wavelengths for custom test conditions. We stress the samples to a maximum common irradiance across the chamber of approximately 150,000 W/m2 and can set the test at 100-hour increments.
