<p>The device has two voltage measuring devices to respectively measure voltage across a full-wave rectifier (3) and a sensor resistor (6) that is in series with a LED (2). A control unit (9) reduces the LED current when the rectifier voltage is high. A capacitor (11) powers the LED when the rectifier voltage is below the LED threshold value, where the capacitor is charged when the rectifier voltage is above the value. An independent claim is also included for a process for operating an LED of a bicycle.</p> |
