A new report by the IEA 4E Solid State Lighting Annex provides a look across the body of literature on lifetime definitions for LEDs and LED products. The reports looks at failure mechanisms, accelerated life tests
The IEA-4E SSL Annex is updating the voluntary quality and performance requirements which address product attributes such as colour, lifetime, power, and efficacy for common SSL lamps and luminaires. The product performance requirements offer a limited
Publication of Final Report: Visual Perception under Energy-Efficient Light Sources – Detection of the Stroboscopic Effect under Low Levels of SVM
The SSL Annex is pleased to publish today the Final Report for a research project that examined visual perception associated with temporal light modulation, and more specifically the stroboscopic effect. An interim draft report on this study was published in December 2018, and it has since been extended in sample size and in the scope of analysis and has undergone peer review.
The European Commission published the new ecodesign and energy labelling regulations that apply to all lighting products in Europe. Called the “One Lighting Regulation”, the scope of coverage applies to all light sources – incandescent, halogen, fluorescent, high intensity discharge and solid-state lighting sources. The regulations set out mandatory quality and performance requirements as well as labelling, informational and product registry database requirements.
The IEA 4E SSL Annex and the Danish Technical University (DTU) worked together to plan a one-day seminar covering recent research on health and testing, including topics such as temporal light modulation and lifetime. The seminar also covered the new EU energy label for lighting and the product registry database.
As part of the work of the Interlaboratory Comparison 2017 (IC 2017), the SSL Annex has today published the Nucleus Laboratory Comparison Report. This report presents the results of a comparison between the Korea Institute of Lighting and ICT (KILT), Korea, and Laboratoire national de métrologie et d’essais (LNE), France. This work was conducted to verify their measurement uncertainties and to bring equivalence of their measurements of the IC 2017 artefacts. Based on the results of this comparison, the correction factors for equivalence of measurements by the two Nucleus Laboratories as prescribed in IC 2017 Technical Protocol were determined.
KILT and the SSL Annex held an International Seminar on Certification, Standards & Requirements of Solid State Lighting – 4 April 2019
An international seminar on certification, standards and requirements was held on 4 April 2019 at Le Meridien Hotel in Seoul, Korea. The Korean Institute of Lighting and ICT (KILT) and the SSL Annex worked together to organise this seminar which included leading experts from both the SSL Annex and regional governments.
The CIE is holding a Tutorial and Practical Workshop on CIE S 025, the first international measurement standard for LED lamps, luminaires and modules. This workshop will be held at the Russian Lighting Research Institute (VNISI) in Moscow on 5 – 7 November.
The SSL Annex held a one day conference in Sydney with presentations by the SSL Annex’s Experts on a range of topics related to LED lighting, efficiency and quality. The conference gathered over 50 Australian lighting experts from industry, research and government.
Launch of IEA 4E SSL Annex 2017 Interlaboratory Comparison of Goniophotometer Measurements (IC 2017)
The IEA 4E Solid State Lighting Annex today is formally announcing a global interlaboratory comparison for goniophotometers (in short IC 2017). With 70 labs from around the world pre-registered, IC 2017 has the potential to be the largest single interlaboratory comparison of goniophotometers. The programme is designed in compliance with ISO/IEC 17043 to serve as a proficiency test for SSL testing accreditation programmes that recognise this comparison and it is based on the new CIE S 025/E:2015 test method for LED equipment.
The IEA 4E Solid State Lighting Annex today published a new report promoting CIE’s new global test standard. The report, entitled “Application Study of CIE S 025/E:2015”, evaluates the new international standard for use by key stakeholders as the basis for measuring important quality and performance aspects of LED lighting products. The SSL Annex has concluded that the new CIE standard is suitable for its upcoming global interlaboratory comparison of goniophotometers.
Today the IEA 4E Solid State Lighting Annex published a new policy report titled “Lessons Learned Bringing LEDs to Market” which highlights dozens of initiatives that contributed to the promotion of quality, energy-efficient lighting in the SSL Annex member country markets.
Drawing on the recently published IEA 4E SSL Annex’s quality and performance tiers, Australia and New Zealand explore new legislation for more energy efficient lighting
Australia’s Equipment Energy Efficiency (E3) Program has released a consultation regulation impact statement (RIS) considering policy options to improve the energy efficiency of residential and commercial lighting in Australia and New Zealand.
Pre-Announcement IEA 4E SSL Annex 2017 Interlaboratory Comparison of Goniophotometer Measurements (IC 2017)
Following the previous 2013 interlaboratory comparison where 110 labs from around the world were compared for measurements of LED lighting products, the International Energy Agency’s Energy-Efficient End-use Equipment Solid State Lighting Annex (IEA 4E SSL Annex) is preparing to launch the 2017 Interlaboratory Comparison (IC 2017) for goniophotometer measurements.
New LED performance recommendations help promote global harmonisation of product quality and performance
The IEA 4E SSL Annex published seven new and updated “quality and performance tiers” for popular LED lamps and luminaires. These seven documents offer policy makers and programme administrators guidance on which parameters to consider and the levels that may be appropriate when specifying or regulating LED products. Parameters include efficacy, lifetime, light colour, durability, and many other metrics.
“Smart” lamps combine technology breakthroughs in wireless communications with light emitting diodes (LEDs) to provide many exciting consumer benefits. However, the standby energy use of “smart lamps” can be larger than the energy used for providing lighting, according to a new report from the IEA 4E Solid State Lighting Annex.
Following the launch of the Global Lighting Challenge aiming at deploying 10 billion super-efficient light sources, the IEA 4E SSL Annex today published an Executive Briefing that summarises the best practices, programmes and other initiatives undertaken by its member countries to accelerate the adoption of quality, energy-efficient LED technology in their markets.
