EC EcoDesign LED lamps regulation 1194-2012 now in force

The European Commission’s EcoDesign regulation for directional lightbulbs, LED lamps and related equipment is in force from today.  Headline LED lamp requirements include:

• starting time < 0.5 s;
• Power Factor: P_NOM ≤ 2 W, no PF limit; 2 W < P_NOM ≤ 5 W, PF > 0.4; 5 W < P_NOM ≤ 25 W, PF > 0.5; and P_NOM > 25 W, PF > 0.9;
• and lamp survival factor at 6,000 hrs > 0.9.

The regulation takes effect for LED lamps in September 2013, except for lamp survival and lumen maintenance (from Mar 14) and compliance with ‘state of the art’ dimmer compatibility requirements (from Sept 14).

Energy Star publishes lamp specification V1.0 – draft three

Energy Star has published the third draft of its V1.0 product specification for new LED lamps that includes for the first time performance targets for flicker, dimmer and noise levels.  The key changes over the second draft [see CamSemi blog 6 Jul 12] include:

• abolishing the ‘Commercial Tier’ so PF ≥ 0.7 for P_NOM > 5 W for all LED lamps;
• LED operating frequency now ≥ 120 Hz to counteract flicker;
• proposed performance specifications for dimmable lamps (including minimum light output, flicker index and acoustic noise levels);
• and efficacy now ≥ 55 lm/W for P_NOM < 15 W and ≥ 65 lm/W for P_NOM ≥ 15 W.

Future versions of the specification may include limits for standby power consumption and reduced lifetime requirements for dimmable lamps.  Click to view all V1.0 documents including draft 3 test specifications or contact CamSemi.

ITU approves development of universal power adapter for networking products

The International Telecommunications Union has agreed first stage approval for L1001, a new standard for universal power adapters designed for stationary ICT equipment including modems, set-top boxes, home networking equipment and fixed telephones.

Key efficiency requirements are divided into transitional and target specifications as follows:

• transitional specs for average and light load efficiencies: η_AVE to Energy Star V2; η_10%= (η_AVE–10%) and with NLP < 150 mW;
• target (3 yr) spec: η_AVE to DoE; η_10%= (η_AVE–5%) and NLP < 30 mW (5 V output) or NLP < 75 mW (12 V output).

ETSI updates voluntary standard ES 202 874-1

The European Telecommunications Standards Institute has updated its voluntary ES 202 874-1 standard, which has been driving 10% load efficiency requirements since 2010, to include 12 V 3.2 A on its universal adapter outputs list.  The standard requires NLP < 300 mW but also high efficiencies.  For example:

• 12V 1A: η_AVE > 78% and η_10% > 71%
• 5V 2A: η_AVE > 77% and η_10% > 70%

EC publishes EPS efficiency draft code of conduct V5

The European Commission has published draft revisions to the voluntary 2009 code of conduct on energy efficiency of ‘normal’ and ‘low voltage’ (< 6 V, ≥ 550 mA) external power supplies from 0.3 W to 250 W.  The revisions include details on active and light-load (ie at 10% load) efficiency requirements divided into two tiers or performance levels. Tier 1 becomes effective in January 2014; tier 2 in January 16.

Examples:

• 12V 1A: η_AVE > 80.0%, η_10% > 70.0% (Tier 1); η_AVE > 83.0%, η_10% > 73.0% (Tier 2)
• 5V 2A: η_AVE > 75.9%, η_10% > 65.9% (Tier 1); η_AVE > 78.7%, η_10% > 68.7% (Tier 2)

The target completion date for the CoC revision is December 2012 and with the requirements likely to guide revisions to EC regulation 278-2009 for EPS efficiency and NLP due in 2013.
