New CIE Technical Report: Optical Measurement of LED Modules and Light Engines

LED modules and light engines represent a wide range of very different products with unique physical properties. Thus, they can neither be treated as single LED packages (where measurements refer to a specific junction temperature of a single LED or the average of a single die, multiple-junction LED) nor as complete lamps or luminaires (where measurements refer to the ambient temperature).

This Technical Report describes the methods for the measurement of photometric, radiometric, and colorimetric quantities of LED modules (with or without integrated control gear) and light engines that are connected to DC or AC power supplies. The report specifies the test-point temperature as a temperature reference when taking measurements.

The publication is written in English, with a short summary in French and German. It consists of 38 pages with 17 figures and one table and is readily available from the CIE Webshop or from the National Committees of the CIE.

The price of this publication is EUR 120,- (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.
For any further information please contact CIE Central Bureau, Kathryn Nield, General Secretary, at Babenbergerstraße 9/9A, A-1010 Vienna, Austria, by phone at +43 1 714 31 87 or by email at kathryn.nield@cie.co.at. You may also visit the CIE website at http:/www.cie.co.at

New BJB LED Connector for Linear LED Modules: Book 21 Compliant

New BJB LED Connector for Linear LED Modules: Book 21 Compliant Lampholders were standard in older, traditional lighting systems. Modern LED fixtures that utilize non-replaceable LEDs create several assembly and field-replacement disadvantages. Zhaga Book 21 addresses these shortcomings by standardizing linear 'socketable' LED modules. In accordance with Book ... Read more »

Measuring the Oxygen Content of Blood with LEDs

Measuring the Oxygen Content of Blood with LEDs Pulse oximetry is a non-invasive method for determining haemoglobin (Hb) saturation through oxygen in the blood and heart frequency. It uses the fact that oxygen-rich and oxygen-poor haemoglobin absorb red and infrared light differently. In order to measure the oxygen content reliably, LEDs with ... Read more »
