description This paper presents the electrothermal modeling and control of a light emitting diodes (LEDs) system. The system consists on a Buck-Boost converter operating as the current driver and LEDs distributed along to the heatsink composing the luminaire. The model contemplates electric characteristics of the Buck-Boost converter and thermal characteristics of the luminaire. A control system is developed to regulate the LEDs current and to keep the adequate LEDs operating temperature. At the end, experimental results are presented for validation of the entire proposed system.
