Design flow for the development of optimized LED luminaires using multi-domain compact model simulations

At present, when designing an LED luminaire, different strategies of development are followed depending on the size of the company. Since on LED datasheets there is only limited information provided, companies active in LED luminaire design need to spend lots of effort on gaining additional information before their luminaire is ready for production. SMEs often use empiric approaches leading to approximated luminaire designs, while bigger companies use advanced hardware and software tools to characterize parts, design versions and finally optimize all design steps. In both cases, considerable time and money is spent on prototyping, sampling, and laboratory testing. Digitalization (also known as Industry 4.0 approach) at all integration levels of the SSL supply chain would provide the remedy for these pains. The Delphi4LED European project aims at developing multi-domain compact models of LED (mixing electronic, thermal, and optical properties of LEDs) as digital twins of the physical products to support virtual prototyping during the design of luminaires. This paper provides a quick overview of the Delphi4LED approach aimed at supporting workflows both for SMEs and bigger companies along with some comparison with the traditional luminaire design.
