Proposal to allow LED light source approval based on photometric criteria in place of the current minimum criteria of 1000 lumens.

34. The expert from France proposed to delete a design restrictive requirement (ECE/TRANS/WP.29/GRE/2015/22 and GRE-73-26). This proposal received comments from the experts of Germany and the Netherlands. The expert from Poland suggested a different approach on this issue (GRE-73-21). The Chair invited the experts from France, Germany, Netherlands, Poland, CLEPA and IEC to prepare a revised proposal for the next session.

Proposal to update document GRE/2016/34. At the 73rd GRE session, France proposed to delete a design restrictive requirement (GRE/2015/22 and GRE-73-26). This proposal received comments from Germany and the Netherlands. Poland suggested a different approach on this issue (GRE-73-21). The Chair invited France, Germany, Netherlands, Poland, CLEPA and IEC to prepare a revised proposal for the next session. Based upon the approach proposed in GRE/2015/22 and GRE-73-26, GTB has investigated the specification of minimum levels of flux projected in critical zones of the passing beam distribution. This approach offers a technology-neutral performance based requirement. The result of the GTB study is to propose minimum projected flux requirements in two zones:
a) 15°D-1°U/30°L-30°R to ensure overall adequate illumination of the road and
b) 3.5°D-1°U/30°L-30°R to ensure sufficient range.

30. The expert of GTB presented the results of their study of minimum levels of flux projected in critical zones of the passing beam distribution of a H4 halogen reflector headlamp and a representative LED headlamp (GRE-76-25). Based on these results, he proposed to remove the design-specific requirement of a minimum objective flux (1,000 lm) for LED and halogen light sources and to replace it with a technology-neutral and performance-based requirement (GRE-76-04-Rev.1). The proposal received comments by the experts from France, Germany, Italy, Poland, UK, EC, OICA. As there was no unequivocal support to the proposal, GRE decided to keep it on the agenda of the next session and to pass it to IWG SLR at a later stage.

Proposal to delete the requirement that the total objective luminous flux of all LED modules producing the principal passing (main low) beam of a headlamp be greater than or equal to 1000 lumens because the requirement is design-restrictive, unnecessary given the objective criteria for luminous output and photometric grid points of the regulation, and obsolete given improvements in LED technologies.

43. The expert from France proposed to delete a design restrictive requirement of a minimum luminous flux of 1,000 lm for LED in Regulations Nos. 112 and 123 (ECE/TRANS/WP.29/GRE/2014/35, ECE/TRANS/WP.29/GRE/2014/36, GRE-72-25). The expert from Poland proposed an alternative definition of photometric requirements (GRE-72-24). GRE supported the deletion of the 1,000 lm requirement, but could not agree with the requirement for light distribution of the beam pattern proposed as an alternative. GRE invited the expert from France, in cooperation with the expert from Poland, to prepare a revised proposal for consideration at the next session. All GRE experts were invited to contribute.
