Lighting device for bicycle, has electric energy supply module with auxiliary and principle electric powering circuit supplying electrical energy continuously and discontinuously to security and principle light source, respectively
The device has an electrical energy supply module (1) with an auxiliary (1A) and a principle electric powering circuit (1B). The auxiliary circuit supplies electrical energy in continuous manner to a security light source (SS) from a dynamo (D), irrespective of speed of a bicycle. The principle circuit supplies electric energy discontinuously to a principle light source (SP) based on the speed that is below threshold speed.
