Working Party on Lighting and Light-signalling | Session 77 | 4-7 Apr 2017
Geneva

The deadline for submission of official working documents to the 77th GRE session is 9 January 2017.

Agenda Item 5.
Regulations Nos. 37, 99, 128 and RE5

11. GRE took note that WP.29, at its November 2016 session, adopted the Consolidated Resolution on the common specification of light source categories (ECE/TRANS/WP.29/2016/111) and assigned it number R.E.5. This Resolution would enter into force in June 2017, simultaneously with the corresponding amendments to Regulations Nos. 37, 99 and 128.

12. The expert from GTB presented proposals for amendments to Regulation No. 128 and to the Consolidated Resolution (R.E.5) which introduce requirements and test specifications for light emitting diode (LED) substitute light sources as well as several new LED substitute light source categories (ECE/TRANS/WP.29/GRE/2017/2, ECE/TRANS/WP.29/GRE/2017/3, GRE-77-02, GRE-77-03, GRE-77-15, GRE-77-22). These proposals were accompanied by collective amendments to Regulations Nos. 48, 53, 74, 86 with the requirements for LED substitute light sources (ECE/TRANS/WP.29/GRE/2017/4). The expert from GTB explained that the proposed approach was based on the following principles:

  • Lamps may be approved with a filament light source and its corresponding LED substitute light source, when fitting in the same holder, and providing an equivalent photometric performance;
  • Lamps equipped with LED substitute light sources should be tested with both the filament lamp and the LED substitute light source.

13. GRE also noted the proposal by GTB to introduce requirements for the use of LED substitute light sources in the new LSD Regulation (GRE-77-15).

14. The expert of Germany commented on the GTB proposals (GRE-77-29). GRE generally advocated the idea of allowing for LED substitute lights sources, given their high energy efficiency. At the same time, the experts from France, Germany, Netherlands, Spain and UK pointed out the risks associated with the improper use of aftermarket LED products in lamps, which were not approved for such light sources, and called for developing a set of preventive measures, including raising public awareness and giving warnings to consumers. Several technical issues were also questioned, in particular, the proposed G-marking for LEDs with a correlated colour temperature below 3,000 K. GRE invited GTB to address the comments received and agreed to continue the consideration of this issue at the next session on the basis of revised documents to be prepared by GTB.

15. The expert from GTB presented proposals for amendments to Regulation No. 128 and to the Consolidated Resolution (R.E.5) that introduce a new LED light source category for forward lighting applications (ECE/TRANS/WP.29/GRE/2017/5, ECE/TRANS/WP.29/GRE/2017/6, GRE-77-04, GRE-77-12, GRE-77-13). He explained that GTB had abandoned the concept of “thermal grade” and instead proposed the introduction of a maximum test temperature to ensure interchangeability between approved light sources from different manufacturers. GRE also noted the proposal by GTB to incorporate LED light sources into the new RID Regulation (GRE-77-14).

16. The expert from UK requested more time to study the proposals. The expert of Germany proposed modifications to the notion of “maximum test temperature”. GRE decided to revert to this issue at the next session and invited GRE experts to study the proposals and to send their comments to GTB and IWG SLR.
