DELPHI4LED (2016–2019) focused specifically on translating physical LED measurements into standardized multi-domain compact models used across the lighting industry.
PI LIGHTING SARL
Swiss LED technology SME combining device-level modeling expertise with AI-driven digital twins for smart lighting infrastructure.
Their core work
Pi Lighting is a Swiss SME specializing in advanced LED lighting technology and its integration with digital intelligence. Their work spans the full arc from low-level LED characterization and compact modeling to high-level AI-driven management of lighting infrastructure. In the DELPHI4LED project, they contributed to standardized multi-domain models for LED behavior — foundational work that enables more accurate product design and lifetime prediction. In AI-TWILIGHT, they moved up the stack to building digital twins for real-world lighting installations, applying Industry 4.0 methods to predict failures, optimize maintenance, and digitalize the design workflow.
What they specialise in
AI-TWILIGHT (2021–2025) built an AI-powered digital twin system for monitoring and managing lighting installations, with a digitalized design flow as a core output.
AI-TWILIGHT explicitly targets lifetime prediction of LED infrastructure as a key deliverable, enabling condition-based maintenance decisions.
AI-TWILIGHT positions lighting infrastructure within a front-end Industry 4.0 context, connecting physical assets to data-driven operational workflows.
How they've shifted over time
Pi Lighting's trajectory shows a deliberate progression from component-level science toward system-level intelligence. Their first project (2016–2019) was firmly grounded in device physics — measuring LED behavior and encoding that knowledge into reusable compact models, the kind of work that feeds standards bodies and simulation tools. By 2021, their focus had shifted sharply upward: instead of modeling individual LEDs, they were building AI systems that manage entire lighting installations as living digital assets. The thread connecting both periods is LED as the core subject, but the sophistication of the applied layer around it has grown considerably.
Pi Lighting is moving toward becoming a software-and-intelligence company for the lighting sector, with physical LED expertise as the foundation — making them an increasingly relevant partner for smart building, smart city, and industrial IoT consortia.
How they like to work
Pi Lighting participates exclusively as a consortium partner rather than a coordinator, suggesting they contribute specialized technical expertise rather than lead project management. Their two projects pulled in 34 distinct partners across 10 countries, indicating comfort operating inside large, multi-national research consortia — both an ECSEL-RIA (a joint undertaking with strong industrial participation) and a standard RIA. This pattern fits a company that brings focused, sector-specific know-how into broader collaborative structures rather than driving the agenda themselves.
Despite only two projects, Pi Lighting has accumulated 34 unique consortium partners across 10 countries — an unusually broad network for a small SME, reflecting the large consortium structures typical of ECSEL-JU and Horizon RIA projects. Their footprint is pan-European, with no obvious concentration in Switzerland alone.
What sets them apart
Pi Lighting occupies a rare niche: a small company that bridges rigorous LED device science (compact modeling, measurement standards) with applied AI and digital twin engineering. Most lighting companies either stay in hardware or jump straight to building controls — Pi Lighting has built credibility at both ends. For a consortium needing someone who can translate physical LED behavior into a data model that an AI system can act on, there are very few SMEs in Europe with documented experience doing exactly that across two successive research projects.
Highlights from their portfolio
- AI-TWILIGHTLargest funding received (EUR 505,219) and the most forward-looking project — combining AI, digital twins, and Industry 4.0 for lighting infrastructure, which positions Pi Lighting at the intersection of three high-demand technology areas.
- DELPHI4LEDParticipation in a standards-oriented ECSEL-RIA project on LED compact modeling demonstrates foundational technical credibility and ties Pi Lighting into the European semiconductor and photonics research ecosystem.
