Beschreibung
Zusammenfassung:	The active lighting device of a bicycle includes a first optical system with a first light source for long-distance illumination, controlled by a control unit, and a second optical system with a second light source for short-distance illumination, controlled by the control unit. It includes a light sensor for determining the light intensity of a location in which the bicycle is situated and allows the control unit to adapt the light intensity of the light sources, if they are activated and if the ambient light intensity is below a determined light threshold. Moreover, a speed sensor is provided for determining the speed of the bicycle in use on a path, so that the control unit controls the activation of the first light source from at least one determined speed threshold. An orientation detector is provided for orienting the light sources depending on a curve travelled by the bicycle in use.
