The advent of Electroluminescent Diode (LED) technologies has been one of the major sources of energy reduction in the domestic lighting sector as well as in the automotive and aerospace fields. In vehicles, the use of LEDs allows a reduction of 110W to 40W useful for the function Dipped beam is a gain of about 350W in energy consumption of the vehicle with a combustion engine (from 2 to 5g of CO2 per kilometer) [1]. In 2010, Adaptive Driving Beam (ADB (also called glare-free high beam) appeared. The objective of the ADB is to adapt the beam to the presence of vehicles in both directions to improve the driver's long-range visibility without causing discomfort, distraction or glare to other road users. The ADB is a lighting function with high added value in terms of comfort and road safety [2]. The new lighting technologies make this function more and more efficient and effective with a resolution and the number of pixels that increases.
