International Lighting Seminar: Perspectives on Sustainability, Performance, Health & Smart Lighting
An international lighting seminar organised by the International Energy Agency’s (IEA) 4E Solid State Lighting Annex and the Swedish Energy Agency.
Digital lighting technology (Solid State Lighting, SSL) is now completely taking over the lighting market. The seminar gives you, as a supplier, consultant, researcher or otherwise involved in lighting issues, a unique opportunity to learn about the work of the SSL Annex’s international experts. In the seminar, SSL Annex’s experts provide an insight into a number of current issues:
- What is happening in ecodesign?
- How did international co-operation on market data accelerate the phase out of fluorescent lamps in Europe?
- Resource efficiency, product longevity and reparability – the next big challenge?
- Ecodesign for Sustainable Products Regulation
- How declared performance differs from test results – and what we can do about it
- A test method cheaper, more realistic and easier evaluation of durability (now used in the Ecodesign Regulation)
- SSL Annex’s recommended requirements for lighting products – and how they can be used
- International comparisons of laboratories’ testing capacity – the third global test begins
- Smart lighting – and energy smart lighting
- New ways to describe colour and colour rendering – what could be the standard of the future?
- Reducing light modulation for health and well-being – not just a matter of vision
The SSL-Annex is managed by six countries (Australia, Denmark, France, South Korea, Sweden and the UK) within the framework of the IEA’s 4E (Energy Efficient End-use Equipment) technology co-operation, in which some 15 countries participate.
In cooperation with test labs and international stakeholders, SSL-Annex experts evaluate test methods and test capacity of labs, compare claims with test data, develop general and harmonised requirements for lighting products that can be used by individual countries and international organisations. In addition, new technology applications such as smart lighting technology, LiFi, etc. are monitored and analysed. Light and health is an important aspect of the cooperation as energy efficient lighting should never have negative health effects.
Moderator: Prof Georges Zissis, Chair of the SSL Annex, La Place University Toulouse
