    Electro-thermo-optical Characterization of LED / OLED / LD used in automotive environment


  • Résumé

    The emergence of technologies Emitting Diodes [LEDs] was one of the major sources of energy consumption reduction both in the field of domestic lighting as in the automotive and aeronautics. In vehicles, the use of LEDs reduces from 110W to 40W useful for 'code' function or a gain of about 350W in power consumption of the vehicle engine (from 2 to 5 g of CO2 per kilometer). The aim of this thesis is to improve our knowledge of the different modes of interaction between the different constituents of the LED / OLED / DL and the automotive environment, and then to explain by a model the degradation processes in order, through scientific publications, to influence the suppliers of LED/OLED/DL to develop technological solutions for the automotive environment and automakers to adopt to accelerate their use.
