Advancing Photometry: Illuminating Accuracy for Novel Light Sources
At our institute, we delve into the realm of photometry, the science of measuring visible light as it's perceived by humans. Our focus is on revolutionizing the accuracy of energy efficiency measurements for groundbreaking light sources, including LEDs and OLEDs.
Shaping the Future of Light Measurement
In the pursuit of a greener world, the accurate measurement of light sources holds paramount importance. As lighting constitutes a significant portion of energy consumption, determining the energy efficiency of lamps is essential. This assessment demands precise measurements of both luminous flux (the light output perceived by humans) and the active electrical power consumed. However, these measurements are not without challenges—especially when it comes to novel light sources like light emitting diodes (LEDs).
Equipped for Excellence
The Metrology Research Institute is armed with an impressive arsenal of photometric equipment, ranging from integrating sphere detectors and sources to standard lamps, photometers, and luminance meters. These advanced tools empower us to conduct comprehensive measurements and calibrations across all critical photometric quantities. Our capabilities span luminous intensity, illuminance, luminous flux, and luminous efficacy.
Guiding Progress, Pioneering Accuracy
As the world shifts toward more sustainable lighting solutions, our research stands at the forefront. We're committed to advancing photometry, boosting the precision of measurements, and reshaping how we perceive, understand, and utilize light. Our pursuit aligns with a greener, brighter future—one illuminated by knowledge and powered by innovation.
