CIE Announces Availability of New Documentation: Test Method for OLED Luminaires and OLED Light Sources

The new CIE International Standard S 025-SP1/E:2019 is a supplement to CIE S 025:2015 Test Method for LED Lamps, LED Luminaires and LED Modules specifies the requirements for measurement of electrical, photometric, and colorimetric quantities of OLED luminaires and OLED light sources. These sources were not covered by CIE S 025:2015 even though they are very similar in regard to the measurement techniques. Recent improvements in the technology and availability of OLED-based lighting products raised the necessity to extend CIE S 025:2015 to OLED products.

OLED luminaires and OLED light sources offer a large variety of configurations with respect to geometry and/or color. The electrical, photometric and colorimetric performance of these devices need to be determined for each configuration unless it can be shown that a given configuration has equivalent performance to another.

The relevant clauses of CIE S 025:2015 are considered in terms of their applicability to measurement of OLED luminaires and OLED light sources and, where required, specific requirements are given. For measurements of LED lamps, LED luminaires and LED modules, the requirements of CIE S 025:2015 remain unchanged.

The document aims in particular to cover measurement methods for testing the compliance of OLED light sources and OLED luminaires with the photometric and colorimetric requirements of OLED performance standards issued by IEC/TC 34 "Lamps and related equipment", in particular IEC 62922.

This CIE International Standard has been approved by the CIE National Committees. It is readily available from the CIE Webshop or from the National Committees of the CIE.

Price of this CIE International Standard: EUR 72,- (Members of a National Committee of the CIE receive a 66,7 % discount on this price – please approach your NC for information on accessing this discount).

About the CIE:

The International Commission on Illumination – also known as the CIE from its French title, the Commission Internationale de l´Eclairage – is devoted to worldwide cooperation and the exchange of information on all matters relating to the science and art of light and lighting, colour and vision, photobiology and image technology.
With strong technical, scientific and cultural foundations, the CIE is an independent, non-profit organization that serves member countries on a voluntary basis. Since its inception in 1913, has been accepted as representing the best authority on the subject and as such is recognized by ISO as an international standardization body. As such the CIE is recognized by ISO as an international standardization body, publishing global standards on the fundamentals of light and lighting.
