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.

The collective amendment presented in GRE/2016/34 extends the usage of LED light sources of UN R128 to front lighting Regulations Nos. 19, 98, 112, 113 and 123. The introduction of LED light source categories under UN R128 for forward lighting applications (front fog, low beam, high beam,
AFS) is planned for 2017. This presentation explains the plans, timeline, and dependencies GTB proposes to address through the collective amendment, especially within the context of the simplification of lighting regulations program.

Analysis raising concerns regarding the proposal to establish photometric requirements for Class B1 based on average real performance of present Class B (halogen/LED) without reference to design specifications such as the luminous flux of light source.

Presentation concerning the proposal to introduce a new optional “Class B1” headlamp.

Supplement 3 to the 01 series of amendments to UN R 98, 112, and 123 deleted the measurement point HV from the photometric requirement table. The HV measurement point, however, remains a requirement for checking photometric stability. This proposal removes the HV measurement point from the photometric stability requirements for the passing beam. The HV measurement point remains a valid for the driving beam.

This collective amendment on the stability of photometric performance during the heat test, with particular reference to the movement of the cut-off line, clarifies the test cycle and also aligns the requirements of Regulations Nos. 19, 98, 112, 113 and 123. In addition to resolving problems of interpretation presented by the current text, this collective amendment will assist the Informal Working Group “Simplification of Lighting and Light-Signalling Regulations” in drafting the new simplified Regulations which is underway.

This collective amendment extends the usage of LED light sources of UN R128 to front lighting Regulations Nos. 19, 98, 112, 113 and 123 (as presented in the previous session document GRE-75-14). The proposal would allow for the use of regulated replaceable LED light sources according to Regulation No. 128 in all applications where the use of LED modules is already permitted.
