Abstract (en)
[origin: WO2020064823A1] The invention proposes a matrix light source having a plurality of elementary light sources with light-emitting semiconductor elements, and a common substrate in contact with an integrated circuit. The integrated circuit allows a brightness setpoint to be stored for each elementary light source of the matrix source, and comprises a circuit for managing the power supply for each source, allowing the brightness setpoint to be implemented without needing other external controls.
