CIE Metrology of LEDs and LED Modules

A Seminar at the CIE Central Bureau, Vienna/Austria,

November 28, 2012, 13:00 – 18:00 and
November 29, 2012, 08:30 – 13:30

Goal: 
The seminar will summarize fundamental differences in the measurement of traditional light sources and LEDs as well as LED modules.


Target Group: Anybody interested in solid state lighting, the photometry and colorimetry of solid state devices, especially LEDs and LED modules.

Please, note: places are limited and will be assigned on a first come, first serve basis.

Costs: 
EUR 800,-- (excl. 20% VAT)



Subjects to be covered are the following:

1. Fundamental differences between LEDs, LED modules and LED lamps as well as traditional light sources (LED structure, thermal differences,  aging and life-time)
2. The most basic terms used with LEDs and LED modules
3. Photometry of LED devices (differences compared to traditional light sources):
       a.Gonio-photometry, with special emphasis of absolute photometry of LED sources
       b.Integrating sphere photometry
       c.Spectroradiometry, with special emphasis on band-width and stray light effects.
4. Colorimetry of LEDs and LED modules
       a.Tristimulus colorimetry
       b.Problems with the CIE 1931 colorimetric system
       c.CIE TC 1-36 based colorimetry and practical experience

The lectures will be accompanied by demonstrations and hands-on experiments.
