Proposal for a Supplement to the 01 series of amendments to Regulation No. 112
Document GRE/2014/36
11 August 2014

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.

7. (j) | Regulation No. 112 (Headlamps emitting an asymmetrical passing-beam)

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.

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.

67. The expert from France introduced GRE-71-09 and GRE-71-10 proposing to delete an unjustified design restrictive requirement of a minimum luminous flux of 1,000 lm for LED’s in UN Regulations Nos. 112 and 123. While several experts supported this proposal, some others pointed out that those alternative criteria should be developed to guarantee a minimum performance of LED light sources. GRE decided to revert to this issue at the next session and requested the secretariat, in cooperation with the expert from France, to re-issue GRE-71-09 and GRE-71-10 as official documents.
