CIE Division 2 activities 2014/2015

CIE Divisions

Division 1 Vision and Color

Division 2 Physical measurement of Light and Radiation

Division 3 Interior Environment and Lighting Design

Division 4 Lighting and Signalling for Transport

Division 5 Exterior Lighting and Other Applications

Division 6 Photobiology and Photochemistry

Division 8 Image Technology

CIE D2 strategy

• Technical committee work – Increase of efficiency (Webex collaboration, work plans,

deadlines…) – Focus on relevant topics (update of basic documents, LED

photometry) • Scientific symposia

– Selected topics (Monte Carlo, Sampling theory, Advanced correction methods…)

• Tutorials and Lectures

– Increased demand from industry (Measurement uncertainty)

CIE TC2-71 CIE Standard on test methods for LED Lamps, luminaires and modules Chair, Yoshi Ohno (US)

developed a CIE standard

Joint work with

CEN TC169 WG7 Photometry, Chair, Guy Vandermeersch (BE)

developed an equivalent EN standard on SSL test method:

CIE DIS 025 is to be CIE S 025, then ISO/CIE/(IEC) joint standard

CIE DIS 025:2014 Test method for LED Lamps, LED luminaires and LED modules

Future activities

• Review of existing publications • Finalizing that are TC work «close to final» • New workshops and trainings for industry • Identify possible new items for standarization • Identify possible research topics

Possible research topics

1) Traceability/primary realization New primary realization LED-based traceability

2) New metrics for Multi-angle reflectometry BRDF Appearance Flicker Glare
