LED measurement group seeks participants for optical tests

Feb. 7, 2005
A group in the UK is seeking participants for a series of round-robin tests to promote understanding of optical measurement issues
The UK's National Physical Laboratory operates an Optical Radiation Measurement Club, which in December 2002 established an LED Clusters Focused Interest Group (FIG).

The FIG aims to promote a better understanding of optical measurement issues in connection with LED clusters, and enjoys representation by NPL, LED manufacturers, LED cluster and signal manufacturers, optical measurement equipment manufacturers, LED cluster users, and consultancies.

A successful round-robin test was conducted in 2003 using a number of LED cluster artefacts, and the findings of this exercise have been used to identify the measurement issues which require specification or control in order to minimise measurement error and uncertainty.

These measurement issues have been used by the FIG to develop a Best Practice Guide, which is currently in the final stages of drafting.

The LED Clusters FIG is planning a second series of round-robin tests which will be conducted with reference to the Best Practice Guide. Results will be treated anonymously, and participating organisations stand to gain familiarity with the Best Practice Guide.
