CIE is pleased to announce its cooperation with LS 2026 Athens, the IEEE Sustainable Smart Lighting World Conference, taking place from 2–4 December 2026 in Athens, Greece. LS 2026 Athens is a CIE co-branded and CIE-supported IEEE event, reflecting the close collaboration between CIE and IEEE in advancing knowledge exchange and innovation in sustainable smart lighting. The event is organised in cooperation with the CIE National Committee of Greece.
CIE and IEEE share areas of interest across lighting technology, applications and smart systems, with particularly strong connections among experts working on outdoor lighting and related topics within CIE Division 4 Transportation and Exterior Applications. These existing networks provide a strong basis for knowledge exchange and collaboration between the two organisations. The connections between the two organisations are also reflected in the involvement of individual experts. Prof. Georgios Zissis, Chair of the IEEE committees involved in LS 2026 Athens, is currently a member of CIE TC 4-61 Artificial Lighting and its Impact on the Natural Environment, and Chair of CIE JTC 19 Terms and Definitions of Horticultural Lighting. His ongoing involvement in CIE technical work further demonstrates the strong overlap between the CIE and IEEE lighting communities.
LS 2026 Athens will bring together the international lighting community to exchange knowledge across lighting science, smart systems, sustainability, design, education, policy and professional practice. The conference will address a wide range of topics, including lighting technology and innovation, sustainability and energy efficiency, human-centric lighting, architectural, urban and heritage lighting, AI and smart lighting control, as well as measurement, standards, education and practice.

PROGRAMME
The LS 2026 Athens programme will offer a compact, high-quality scientific agenda combining keynoted lectures, technical paper sessions, poster presentations, selected oral presentations, workshops, round tables and networking activities.
All accepted abstracts will be presented in poster format, while selected landmark papers will be scheduled for 15-minute oral presentations. The programme will also include the Career Day “Lighting Futures”, designed to connect companies, researchers and students around lighting careers and emerging directions, as well as round tables with international lighting organisations and meetings with lighting educators.
CIE will be represented at the event by Mr. Tony Bergen, CIE Vice-President Technical and President-Elect, who will deliver a keynote presentation and participate as a panelist.
Prof. Valéry Ann Jacobs, Editor of CIE Division 2 Physical Measurement of Light and Radiation, will also deliver a keynote addressing the current challenges in light pollution research, with a particular focus on the needs for lighting and lighting standardization. Her presentation will also highlight the role and added value of CIE in supporting research and knowledge exchange, including how CIE organizes its technical work through Technical Committees and Research Fora.
Dr. Georgios Paissidis, President of the CIE National Committee of Greece will also contribute to the opening of the conference with welcome remarks.
CIE Expert Dr. Mandana Khanie, Chair of the CIE JTC 18 Lighting Education has been invited to lead a Lighting Educator Workshop, providing an opportunity for educators to exchange on current and emerging topics in lighting education.
A Student Luminaire Competition will also offer students the opportunity to showcase their designs, with winners receiving prizes and all participating students eligible for free conference registration.
Additional activities will include workshops and special sessions, an exhibition and partner area, and a Night Lighting Walk in Athens, linking the city’s heritage with the conference lighting agenda.
