    摘要： The present invention refers to an automotive luminous device (10) comprising
    - a PCB (1) comprising at least a first outer layer (11), a first conductive plane (11, 12), a conductive shield (7, 14) and an intermediate layer (13) arranged between the first outer layer (11) and the conductive shield (7, 14), wherein the intermediate layer (13) comprises tracks (2);
    - an electroluminescent incoherent light source (3) installed in the first outer layer (11) of the PCB (11) and connected to the tracks, the light source being configured to emit a pulsed light flux modulated according to a code, while contributing to a lighting or signalling function;
    - a high frequency driver element (6) installed in the PCB (1), configured to power the light source (3) with a control signal modulated in a frequency higher than 1 MHz, delivered to the light sources through the tracks, so that the light source emits light modulated according to the code;
    - a sensor element configured to receive the pulsed light flux reflected by the outer object.
