Portable active lighting device or same installed on a bicycle
First Claim
1. A portable active lighting device for a bicycle,wherein the device comprises:
- at least one power supply source,a first optical system with a first light source arrangement for long-distance illumination and controlled by a control unit connected to the power supply source, and each whereof, or groups whereof, is/are intended to generate a light beam having a different orientation direction at the output of the first light source arrangement,a second optical system with a second light source arrangement for short-distance illumination and controlled by the control unit connected to the power supply source, and each whereof, or groups whereof, is/are intended to generate a light beam having a different orientation direction at the output of the second light source arrangement,a light sensor for determining the light intensity of a location wherein the bicycle with the lighting device is situated and for supplying a measurement signal to the control unit, which is arranged so as to automatically activate at least the second optical system if the ambient light intensity falls below a determined light threshold, and so as to adapt the light intensity of some light sources or of some groups of light sources of the first optical system if activated and/or of the second optical system, anda speed sensor for determining the speed of the bicycle in use on a path or road, and for supplying a measurement signal to the control unit in order to activate the first light source arrangement of the first optical system from at least one determined speed threshold.

Abstract
An active lighting device of a bicycle includes a first optical system with a first light source arrangement for long-distance illumination, which is controlled by a control unit, and a second optical system with a second light source arrangement for short-distance illumination, which is controlled by the control unit. A light sensor determines the light intensity of a location of the bicycle 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 threshold. A speed sensor determines the speed of the bicycle, so that the control unit controls the activation of the light sources of the first light source arrangement from a speed threshold. An orientation or inclination detector selects and adjusts the light intensity of light sources.
