UN R128: Proposal for Supplement [8]

Source(s)

GTB

Date

10 Aug 2018

Status

Superseded

Subject

UN R128 LED Light Sources

Meeting(s)

GRE | Session 80 | 23-26 Oct 2018

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)

The current text of UN R128, Annex 4, paragraph 1.2. allows only for a decrease of luminous flux from 1 minute to 30 minutes. This has proven to be unnecessarily design restrictive as the drive electronics in a stabilized light source can lead to a slight increase in the luminous flux from 1 minute to 30 minutes. Therefore, this proposal would allow a limited increase of luminous flux from 1 minute to 30 minutes within the given minimum and maximum requirements. This proposal relates to document GRE/2018/48 retaining requirements for LR4 category light sources which would otherwise have been impacted by the present proposal.

GRE | Session 80 | 23-26 Oct 2018

22. The expert of GTB introduced amendment proposals that modified light source category LR4 in UN Regulation No. 128 and in the Consolidated Resolution R.E.5 (ECE/TRANS/WP.29/GRE/2018/48, ECE/TRANS/WP.29/GRE/2018/49 and Add.1). GRE adopted the proposals and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their March 2019 sessions as draft Supplement 9 to the original version of UN Regulation No. 128 and draft amendment 3 to R.E.5. GRE noted that both amendments are part of the same package and should enter into force on the same date.

WP.29 | Session 176 | 12-16 Nov 2018

81. WP.29 noted that GRE considered and adopted a set of amendment proposals on the use of LED substitute light sources for light-signalling applications and would continue considering LED substitutes for front-lighting applications. WP.29 was also informed that GRE had adopted new series of amendments to UN Regulations Nos. 10 (Electromagnetic compatibility) and 53 (Installation of lighting and light-signalling devices for L3 vehicles).
