Working Party on Lighting and Light-signalling | Session 82 | 22-25
Oct 2019
Geneva
The deadline for the submission of official working documents for this session is 29 July 2019.
Agenda Item 5.
UN Regulations Nos. 37 (Filament lamps), 99 (Gas discharge light sources), 128 (Light emitting diodes light sources) and the Consolidated Resolution on the common specification of light source categories
Guide prepared by the GRE Substitutes/Retrofits Task Force to criteria for specifying LED substitute light source categories as equivalents for corresponding fliament light source categories.
GRE/2019/15
UN R128: Proposal for Supplement [10] (GTB)
UN R128: Proposal for Supplement [10]
Proposal to insert a minimum luminance gradient as an alternative criteria. The current text requires a certain “asymmetry” of the Light Emitting Area (LEA) in order to ensure a “minimum worst-case gradient”; however, this requirement has been deemed too design-restrictive.
GRE/2019/16
RE5: Proposal for amendment [1] to version [2] (GTB)
RE5: Proposal for amendment [1] to version [2]
Proposal to amend light source categories L1A/6 and L1B/6 in the Consolidated Resolution on the common specification of light source categories (R.E.5).
Proposal from the GRE Task Force on Substitutes/Retrofits to introduce a new light emitting diode (LED) substitute light source category H11/LED for road illumination applications.
clarify paragraph 2.1 with regard to definitions: “All the definitions given in the latest series of amendments to UN Regulation No. 48 in force at the time of application for type approval shall apply, unless otherwise specified in this UN Regulation or in the pertinent installation UN Regulations Nos. 53, 74 and 86.”
amend the inboard visibility angle for rear position lamps in pairs in the new UN Regulation on Light-Signalling Devices (LSD)
Use of LED substitute light source(s) is allowed and does not constitute a change of the lamp type. However, lamp performances shall be tested during type approval also with the LED substitute light source. Approval of the lamp using filament light source(s) is a prerequisite for approval of the lamp using LED substitute light source(s).
Testing with LED substitute light sources is exempted from conformity of production control.
The technical description shall include notice that the lamp also has to be approved with the LED substitute light source(s) according to UN R128 if the applicant has so determined.
The approval marking or the Unique Identifier as well as the category or categories of LED substitute light source(s) prescribed, if any, shall be visible.
The indication of both the holder of the filament light source and of its LED counterpart light source, if any, shall be explicitly provided.
Introduce requirements for automatic switching from DRL to headlamp(s) if the maximum luminous intensity of DRL is above 700 cd.
This proposal (WP.29/2019/81) was adopted by the World Forum. Forty Contracting Parties out of the 55 applying UN R148 were present for the vote by AC.1. Forty voted in favor with zero against and zero abstaining.
