Lighting device active portable or placed on a bicycle.

The device (1) active lighting of a vehicle comprises a first optical (has) with a first arrangement (6) of light sources for illumination at a great distance, which are controlled by a control unit (2), and a second optic (d) with a second arrangement (7) of light sources for illuminating a short distance, which are controlled by the control unit. It comprises a light sensor (3) to determine the light intensity of a place where the vehicle and permit the controller to adjust the intensity of the control light of the light sources, if enabled and if the intensity of ambient light is below a predetermined light threshold. In addition, there is a speed sensor (4a, 4b) for determining vehicle speed when used on a path, for that the control unit controls the activation of the light sources of the first light source arrangement from at least one predetermined speed threshold. It is also provided an orientation detector or tilt (5a, 5b, 5c) for selecting and setting in luminous intensity at least some light sources or certain groups of light sources of the first and second arrays of light sources.
