The present invention provides a headlamp capable of producing different light beams and fitted with a dynamic control mechanism for controlling the brightness minimizing light interference in all situations. The lamp comprises a light source with LED-type diodes; means for controlling the brightness and/or the geometry of the light beam; capturing means for generating an electrical signal representative of the reflected light intensity of the area illuminated by said light beam onto an illuminated object; and a control unit for generating control signals from the information generated by said capture system. The lamp has capturing means includes a focal system having a variable field under control of the control unit. Preferably, the capturing means includes at least two sensors with fixed focal length or, alternatively, a single sensor may be combined with a single controllable focal system electrically.
