Light MeasurementThis newsflash is fully dedicated to light measurements, with the LED event coming up next week,
Enjoy reading,
The LED Event takes place on
R&D managers, engineers, developers, and lighting designers bring the LED Event a visit to see the newest possibilities. The increasing possibilities of electronics and the rapid development of LED technology offering more opportunities to create LED applications. We will give a lecture about: LED Flicker – where we are with test methods and standards? Get your free entrance ticket here
Rapid developments in LEDs over the past decade have created a major growth market with completely new applications. Full color displays for large areas only became possible with the introduction of high-intensity blue LEDs, while highpower white LEDs are becoming widely used in general lighting and the automotive industry. These applications have placed increasingly stringent demands on the optical characterization of LEDs and Solid-State Lighting devices. Specific expertise is needed in order to achieve precise and reproducible results.
This handbook discusses the special characteristics of LEDs and emerging OLEDs. It provides an overview of state-of-the-art measurement equipment and gives recommendations for obtaining accurate measurement results. The main goal of this handbook is to give readers new to this subject an introduction into LED metrology. However, this handbook is also a useful reference work for more experienced readers.
At the LED event we the Hardcover Handbook of LED and SSL Metrology can be purchased for the special price of € 50,-
Over the past decade UV LEDs have emerged as a highly attractive alternative to conventional UV emission sources. They are cost effective and energy efficient devices in a small housing. These advantages allow new fields of applications and access to a larger group of users – even in the consumer market, e.g. water purification. Dr. Tobias Roesener, Product Manager at Instrument Systems, explains what makes accurate measurement of UV LEDs so complicated and what the crucial requirements on the measurement equipment are. In addition, he discusses calibration and stray light issues.
Evaluating the flicker of LED lighting systems requires an extremely high level of precision due to the rapid response of LEDs to changes in the electrical supply. Such evaluations are done by measuring the amplitude and frequency of any modulation of the light (flicker measurement using the BTS256-EF). BTS256-EF – Highquality, handheld meter with flicker evaluation function
At the LED event we are more then happy to demonstrate the BTS256-EF, with a test booth where you can see the difference between light with a flicker component and flicker free light.
In the October issue of LEDs Magazine, the article “Understand how to measure luminous flux and radiant power” covered some of the basics of metrology for the solid-state lighting (SSL) industry. This article continues the metrology theme, covering luminous and radiant intensity measurements and providing a discussion of uniformity and glare. The prior article and this article have been excepted from a chapter of the newly-published Handbook of LED and SSL Metrology reference book.
We look forward to supplying you with all the material and information you need and answering any question.
