Meetings • 1st meeting: 2017-12-14, Aachen (report: TFSR-01-11) • 2nd meeting: 2018-02-06, Bonn (report: TFSR-02-05) • 3rd meeting: 2018-03-27, Brussels (report: TFSR-03-09) • 4th meeting: 2018-06-06 Brussels (report: TFSR-04-09) • 5th meeting: 2018-01-30 Aachen (report: TFSR-05-09) • 6th meeting: 2019-05-15 BrusselsParis (scheduled) Two-step approach: • Step 1: LED Substitutes • Step 1A: light signaling applications • Step 1B: road illumination applications • Step 2: LED Retrofits • Technical items • Administrative items

  3. Step 1A: LED Substitutes for light signaling applications • Package of documents approved by GRE80 • R128 • RE5 • R-LSD • R-Installation • Approved by WP29 in March 2019

  4. Step 1B: LED Substitutes for road illumination applications • Detailed discussion started in the 5th TFSR meeting in Aachenon 30 January 2019 • Equivalence criteria have to be extended • TFSR-05-04 • Specific intensity distribution • Specific homogeneity of LEA • Contrast • … • GRE-80-02 • Test voltage • Luminous flux • … • Intensity distribution • Homogeneity of LEA • … • Spectral content • Thermal behavior • …
