Large area multi-chip LED devices, such as chip-on-board (CoB) LEDs, require the combined use of chip-level multi-domain compact LED models (Spice-like compact models) and the proper description of distributed nature of the thermal environment (the C

Besides classical inorganic LEDs, intelligent light sources can be also based on organic LEDs. OLEDs function as surface light sources and manufacturing of large area light sources is feasible with OLED technologies. Despite their lower luminous effi

Organic LEDs can be used not only in displays but also in intelligent light sources. Unlike inorganic LEDs, OLEDs do not function as point-like but as surface light sources since manufacturing of large area light sources is more feasible with OLED te
