2b.Please comment on any issues of significance which might have an impact upon
materially affected or interested U.S. parties.
Issues important to the USA:
  • 24 June 2011: LED Workshop
  • IEC 62717 - Performance standard for LED modules: The workshop discussion focused on comments (34A/1471/RVN) provided to 34A/1445/NP for improving the document after a successful NP vote. Major issues were as follows.
  • Guy Vandermeersch explained comments BE-1 and BE-2 requesting improved luminaire photometry conditions and photometry stabilization criterion to coordinate with LM-79. Consensus language was recommended by the workshop participants.
  • Comment FR-10: Lumen maintenance during a temperature accelerated stress test is considered acceptable if the lamp simply remains operable avoiding catastrophic failure (no light).
  • Comment UK-2 (and related): The workshop recommended dropping the confidence interval approach and adopting simplified statistical compliance requirements for luminous flux and module power versus manufacturer rated values. A tolerance on individuals in the population and a separate tolerance on the mean value for sample of N=20 lamps. The specific limits on the mean values remain to be negotiated. Key opposition to imposing tolerances on the mean values came from China (Ms. Yang). She claims the “need” for overstating lumens and understating the power in her region.
  • Comment NL-2: A proposal to factor the power factor into two terms, PF = Distortion * Displacement, is proceeding cautiously. The distortion factor is already standardized in IEC61000-3-2 (TC77) and will be cited. A proposal to limit the displacement factor to 2W was challenged. Support for the proposal seems qualified on determining the technical merits.
  • Comments US-5 and US-6: Photometric testing protocols are still not fully defined for LED modules. A common CIE – IEC body will deal with the development of a photometric test requirement.
  • New comment (not in the RVN): Guy Vandermeersch presents a proposal from Yoshi Ohno of the CIE TC-2 to recast the color specification for LED lamps in terms of (U’, V’) uniform color space coordinates instead of using the ANSI C78.377 quadrangles. It was suggested that he bring a more formal proposal to the next meeting.
  • A new item for Japan NC proposing to combine the failure rate and lumen maintenance curves into a single degradation metric was presented (see PRESCO(TY)035). After the ensuing discussion the workshop participants felt there was not consensus enough to advance the concept in this draft.
  • In a letter received by the workshop chairman the day before this meeting, the China NC (Ms. Yang) proposed using the ISO2859 sampling standard to set sample sizes for compliance testing to N=5. This standard is intended for statistical process control techniques and not compliance testing. Nevertheless, the matter may need to be addressed in the various NCs.
  • IEC 62707-1 LED binning — Part 1: General requirements and white grid
  • Publication of the IEC/PAS 62707-1 in March 2011 was noted.
  • Comments (34A/1455/RVN) to the 34A/1430/NP draft were reviewed. Highlights follow.
  • Comment IT-2: a proposal to align the grid with the definition of white light given in EC Regulation 245/2009 was rejected. In the ensuing discussion the terminology “white” grid in the title of this proposed standard is the cause for confusion. Technically the region covered by the grid is the unsaturated color region. Unfortunately, the workshop could not reach consensus on a correction, so the IT NC was tasked with drafting an explanatory note for inclusion in the standard.
  • Comment JP-1: A proposal was accepted to narrow the scope of the standard to apply to LED chips, dies and packages only and not for larger collections of LEDs such as lamps or modules.
  • USA delegates have committed to author a DTR providing translation of ANSI C78.377 into the white grid coordinates after completion of amendments to the ANSLG document.
  • IEC/PAS 62707-2 LED binning – Part 2: Luminous flux binning. The 34A/1481/DC suggesting an IEC/PAS for luminous flux binning received several negative votes. The workshop consensus was to stop further work on this proposal.
  • IEC/PAS 62707-3 LED binning – Part 3: Forward voltage binning. The 34A/1482/DC suggesting an IEC/PAS for forward voltage binning received a similar pattern of negative votes. The workshop consensus was to stop further work on this proposal also.
  • IEC/PAS 6xxxx — LED Testing and prediction of lumen maintenance
  • The 34A/1480/DC proposing an IEC/PAS received a number of comments opposing the approach from NCs in NL, HU and the US. Most recognized the value of citing and relying upon the IES TM-21 document soon to be published.
  • Following their promise to provide a presentation of TM-21 to the WG at a future workshop, Emil Radkov of the USA delegation gave a detailed overview of the TM-21 document and its development. The presentation was well delivered and received with many questions and dialogue between interested parties.
  • Notably, the authors of 34A/1480/DC elected not to press for corrective modifications to the draft document. Instead, an additional new proposal to use “border functions” to qualify LEDs for lumen maintenance when the curve surpasses a minimum criteria. Extrapolation of the unknown LM curve is assumed to remain acceptable to L70 levels at future testing times.
  • The DE NC offered to host additional meetings on this topic in January 2012. Meanwhile, a teleconference was proposed for later in July 2011 to further discuss the border function and TM-21 approaches.
  • 29 June 2011: Fluorescent Dimming Workshop
  • At the PRESCO WG meeting in Bad Zurzach, CH in April, the Fluorescent Dimming WG was authorized to finalize a proposed draft technical report (DTR) describing the theory and calculations involved in the unified dimming standard for fluorescent lamps. Two very productive working sessions in Washington, DC on 8-June and in Frankfurt, DE on 29-June have resulted in a final draft. A new project proposal NP for the technical report will be prepared based on 34A/PRESCO(MED)023B.
  • Also at the PRESCO WG meeting in Bad Zurzach, CH in April, the Fluorescent Dimming WG was authorized to finalize the datasheets for T5 lamps to include the necessary parameters for dimming. Two very productive working sessions in Washington, DC on 8-June and in Frankfurt, DE on 29-June have finalized the structure and values in the proposed datasheets. A CD for IEC 60081 will be prepared on the basis of 34A/PRESCO(MED)022B.
  • In a complimentary COMEX workshop the method for qualification of dimming electronic control gear was completed. A CD for IEC 60929 will be prepared on the basis of 34C/COMEX(RTN)011D.
  • 30 June 2011: OLED Workshop – Workshop participants met to begin work drafting a new international standard for OLED performance. Comments made to the 34A/1420/NP were reviewed (34A/1456/RVN) in part. Much of the discussion centered on terminology unique to OLED products in the marketplace. It was agreed to seek the advice of the LED terms and definitions WG. Completion of observations to the comments by the project leader will be circulated by 15-Aug-2011. Next steps are to seek PRESCO advice on drafting a PAS, DC, NP, etc…
  • 30 June and 1 July 2011: CFLi Workshop – Editing session for IEC 60969. Comments (34A/1490/INF) received to 34A/1469/DC were considered. Highlights follow.
  • Annex H (Regional Regulations) was rejected as these are not relevant to an IEC Standard
  • Proposals for minimum energy performance specifications (MEPS) put forward by Australia were not recommended. Many regions are already experiencing regulatory MEPS without the need for IEC 60969 to add to this confusion.
  • A discussion regarding performance on phase-cut dimmers was held. Ron van der Brakel updated the WG on the issues of incandescent replacement by CFLi on various dimmer types. A new annex is proposed for performance testing of various dimming attributes. Labeling is considered to indicate the dimmer technology with which each “dimmable” CFLi is compatible. Two separate DC documents should be run in parallel: one for the CFLi revision with an “under consideration” placeholder section to receive a specification from the JWG on dimming compatibility and the other to be received from the JWG for inclusion into this standard when ready.
  • Starting at 0 hours – China wants a specification on the occurrence of non-starting out-of-the-box lamps. This is considered an internal matter for each company and not a standard specification. Certification to the standard is not possible without samples that have at least the minimum number of operable lamps.
  • Lumen marking on the product – Discussion about the information available to the customer at the time of replacement. Should they have the luminous flux available for considering other replacement options? This is not common practice for lamps in the marketplace today. No consensus was reached.
  • The terms “spot and flood” will be dropped from the standard. These are commercial terms and do not need definition in this standard. Evaluate the beam angle and CB intensity against manufacturers’ ratings.
  • Color marking – CCT in K is mandatory for package and data sheets; K or 3-digit code on the product. Packaging shall have CRI or 3-digit color code.
  • Power quality – The displacement and distortion representation is not embraced in TC77. They use PF and THD and have no interest in changing. THD will not be a required marking.
  • Mercury discussion – China feels strongly that liquid Hg is more dangerous than amalgam. They incorrectly reason that the vapor pressure at room temperature is lower for amalgams. Amalgams exist that have the same vapor pressure at room temperature as liguid Hg. After much discussion, the EU regulation 244/2009 marking was recommended: Mark total Hg content as x.x mg. Limits on Hg content are strongly recommended by Australia and China for this IEC standard.
  • Performance requirements and compliance tolerances will be tabulated to replace clauses 7 to 18. The format of PRESCO(AP)008 is accepted. A detailed review of the requirements ensued. Workshop participants recommend tolerances to be developed for both the population and the mean of a 10-piece sample.
  • Starting time requirements at normal line and temperature conditions shall be less than 2 seconds (unless a fasterrating is claimed). Starting at extreme conditions of temperature (-10C) and line voltage (92%) shall be less than 10 seconds. Extreme conditions of temperature may be declared differently by manufacturer.
  • IEC TC34 standards are predominantly written for type testing, i.e. using lamps selected by the manufacturer. Therefore, the sample is not selected randomly from production for compliance determination. With the increased prevalence of regulatory surveillance the TC34 may want to reconsider updating their standards.
  • Life tolerances – Public comments from NEMA to the USDOE Certification, Compliance and Enforcement NOPR were circulated. Very wide tolerances on measured median life of 10-lamp samples will be necessary!
  • Workshop participants recommend removal of photometric methods of measurement from Annex A responding to the written request of the CIE to IEC.
