Embodiment Construction

[0020] In the following description, a portable active lighting device or such device mounted on a bicycle having at least two wheels is discussed. All electronic components known to those skilled in the art are described in simplified form only.

[0021] figure 1 The different components of a portable active lighting device 1 or a device mounted on a bicycle with at least two wheels are shown in a simplified manner. The lighting device 1 mainly comprises two optical systems denoted A and B. As shown in FIG. The first optical system A comprises at least one first light source 16 and the second optical system B comprises at least one second light source 17 . The first light source 16 is provided for remote illumination, preferably with variable intensity. The second light source 17 is provided for close-range illumination, preferably with variable intensity.

[0022] Each light source 16, 17 is a light emitting diode or a group of light emitting diodes that can be selected ...

Abstract

The active lighting device (1) of a bicycle includes a first optical system (A) with a first light source (16) for long-distance illumination, controlled by a control unit (2), and a second optical system (B) with a second light source (17) for short-distance illumination, controlled by the control unit. It includes a light sensor (3) for determining the light intensity of a location in which thebicycle 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 (4a, 4b) 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 (5a, 5b, 5c) is provided for orienting the light sources depending on a curve travelled by the bicycle in use.

Description

technical field [0001] The present invention relates to a portable active lighting device or such device mounted on a vehicle having at least one wheel, such as a bicycle. Preferably, each lighting device has a first optical system having at least one first light source and a second optical system arranged partly on the bicycle, said second optical system having at least one second light source . Background technique [0002] Known ways of properly illuminating the path or road traveled by a vehicle include the use of lighting devices having adjustable configurations of light intensity produced by lamps or other light sources. Such lighting can also be adjusted to direct the beam according to which corners to turn in the dark or to not dazzle drivers of oncoming vehicles on the road. [0003] Patent application WO 2017 / 023293A1 discloses an intelligent lighting system for two-wheeled vehicles such as bicycles. It comprises light emitting diodes or LED devices which can be...
