Light device for object detection

A luminous device for an automotive vehicle, comprising:

• at least one luminous module emitting pulsed visible light modulated by means of a high-frequency luminous code, each luminous module includes at least one driver circuit supplying with electricity via the same driver-circuit output a plurality of light-emitting diodes, the driver circuit being configured so as to modulate, in accordance with the high-frequency code, an electric power received by the light-emitting diodes in order to emit the pulsed visible light, and
• a reception device for receiving the light emitted by the at least one first luminous module, for receiving part of the pulsed light, modulated in accordance with the code, after reflection of the pulsed light emitted by the at least one first luminous module from an object outside the vehicle,
• wherein:
• the modulation frequency is greater than 10 MHz, and
• each light-emitting diode is connected to the same output of the driver circuit by a conductor track, the conductor tracks connecting each of the light-emitting diodes to the driver circuit each having an impedance ensuring the same phase shift at the modulation frequency for all the LEDs, thus ensuring synchronous modulation of the electric power perceived by the light-emitting diodes supplied by the driver circuit.
