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

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.

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 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.

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.

Compressed data package of three documents providing lists of proposals for amendments to lighting regulations within the context of plans for the restructuring of UN lighting regulations.

Proposal to introduce a new optional “Class B1” headlamp. The proposal would establish photometric requirements for Class B1 based on average real performance of present Class B (halogen/LED) but would not include additional design restrictions such as the luminous flux of light source.

Proposal to amend the formula for the dirt mixture used in testing to address an error introduced by Supplement 9 to the 01 series of amendments to UN R45 where the specified quantity of “2 ± 1 parts by weight” of surfactant results in invalid testing. The correct specification should be “2 ± 1 drops” of surfactant. While GTB notes that the specification should eventually be incorporated differently under the pending simplification of lighting regulations, the organization strongly urges amending UN R45 as quickly as possible.

Updated paper on the grouping of lighting regulations under one of three new regulations as follows:
Light Signaling Devices incorporating Regulations 4, 6, 7, 23, 38, 50, 77, 87, and 91
Forward Lighting Devices incorporating Regulations 19, 98, 112, [ 113 ], 119, and 123
Retro-Reflective Devices incorporating Regulations 3, 27, 69, 70, and 104

A mock-up for the proposed regulation consolidating the current forward lighting device regulations, illustrating how the application of the device subparts would be shown in the “Status of the 1958 Agreement” registry of applications, approval authorities, and technical services. The approach would be to add a column listing the lighting functions for which each Contracting Parties accepts/issues approvals.
