Flicker

Almost any light source that emits light shows fluctuations in light output. These fluctuations can be caused by mains or power supplies / drivers and differs for each type of light source and type of power supplies. Especially from health and well-being point of view, determination of flicker of light emitting sources becomes more and more important. Rapidly growing applications of LED/SSL products demand for quality assessment which include measuring flicker. In lighting industries, the flicker value is typically expressed as a percentage or flicker index. Admesy offers products and support to carry out flicker measurements according to international standards.

The Asteria light meter is capable of detecting flicker at high sample rates [186567] samples per second. Currently flicker percentage, flicker index as well as IEEE 1789 flicker recommendation are supported. For more information about flicker measurements of lighting systems, please take a look at our application guide and technical note.

How are you measuring?


Consumers are used to enjoy top-quality displays in their mobile phones, tablets, laptops and even cars. Emerging technologies such as lighting surfaces for office and home illumination are expected to look equally perfect. Both displays and luminous surfaces are the main application areas for imaging colorimeters.
