Abstract (en)
[origin: WO2020002264A1] Method for managing the power of an LED projecting optical module (1) for a motor vehicle, said method comprising: applying a nominal current (5) to the optical module; and decreasing (6) the current applied to the optical module when the temperature in the optical module is higher than or equal to a first threshold (T1). Furthermore, the current applied to the optical module is increased (7) when the temperature in the optical module is lower than or equal to a second threshold (T2), the temperature of the second threshold (T2) being lower than the temperature of the first threshold (T1).
