Abstract

Normal lighting for the bicycle is powered by a dynamo. The new lamps illuminate when the bicycle is temporarily stationary. The dynamo AC output is rectified by diode (2) and charges up a capacitor (3) of extremely high capacity via a voltage regulator (3). In the stationary bicycle condition, the capacitor discharges through a resistor (10) and PNP transistor (9) to the LED (11). ADVANTAGE - Increased safety arrangement for cyclist requiring no battery which can became flat and incurs no switch-over delay.

Description

Die Erfindung betrifft eine Einrichtung zum Schalten des Standlichtes mit Leuchtdioden für nichtmotorisierte Fahrzeuge, insbesondere Fahrräder, deren elektrische Verbraucher nur in Bewegung durch einen Wechselstrom­ generator mit Strom versorgt werden.The invention relates to a device for switching the Parking lights with LEDs for non-motorized Vehicles, especially bicycles, their electric Consumers only move through an alternating current generator can be powered.

Die Stromversorgung der elektrischen Verbraucher von nicht­ motorisierten Fahrzeugen, insbesondere von Scheinwerfer und Rücklicht von Fahrrädern erfolgte bisher durch allgemein bekannte Fahrraddynamos, deren Antrieb durch die Drehung des den Dynamo antreibenenden Rades erfolgte.The power supply to the electrical consumers from not motorized vehicles, especially headlights and Backlight of bicycles has so far been made by general well-known bicycle dynamos, which are driven by the rotation of the the dynamo driving wheel was done.

Nachteilig bei dieser Art der Stromversorgung ist, daß bei Stillstand des Rades die Beleuchtungsanlage dunkel bleibt und in dieser Situation der Radfahrer von anderen Verkehrs­ teilnehmern oft nicht oder zu spät wahrgenommen wird.A disadvantage of this type of power supply is that The lighting system remains dark when the wheel comes to a standstill and in this situation the cyclist from other traffic participants are often not noticed or noticed too late.

In DE-OS 24 27 740 wurde vorgeschlagen, daß die Beleuch­ tungsanlage durch zusätzlich am Fahrrad angebrachte galva­ nische Elemente mit Strom versorgbar ist, wobei ein an sich bekanntes Relais mit einer Elektronikschaltung, die ein zusätzliches Zeitglied enthält, eine automatische Umschaltung von Dynamo auf Batteriebetrieb sowie eine automatische Abschaltung der Batteriespannung nach einer bestimmten Zeit garantiert.In DE-OS 24 27 740 it was proposed that the lighting system by means of an additional galva attached to the bicycle African elements can be supplied with electricity, one at known relay with an electronic circuit that contains an additional timer, an automatic one Switching from dynamo to battery operation and one automatic shutdown of the battery voltage after a  guaranteed certain time.

Die DE-OS 25 19 837 schlägt vor, daß der Dynamo über eine Einweg-Gleichrichterschaltung und eine nachfolgende elektro­ nische Schaltung Strom an die Beleuchtungsanlage und an eine aufladbare Batterie abgibt.DE-OS 25 19 837 proposes that the dynamo have a One-way rectifier circuit and a subsequent electro African circuit electricity to the lighting system and to a rechargeable battery.

Nachteilig dieser Lösungen ist es, daß Primär- oder Sekundärelemente benötigt werden und diese nach einer gewissen Zeit gewechselt werden müssen.The disadvantage of these solutions is that primary or Secondary elements are needed and this after a have to be changed after a certain time.

Ein weiterer Nachteil ist, daß durch Auslaufen der Batterien die Elektronik zerstört werden kann.Another disadvantage is that by battery leakage the electronics can be destroyed.

Ziel der Erfindung ist es, daß die Primär- und Sekundär­ elemente entfallen und durch einen nichtwechselbaren Energiespeicher ersetzt werden.The aim of the invention is that the primary and secondary elements are eliminated and by a non-exchangeable Energy storage to be replaced.

Aufgabe der Erfindung ist es, daß eine nichtwechselbare Energiequelle eingesetzt wird, welche die Primär- und Sekundärelemente ersetzt.The object of the invention is that a non-exchangeable Energy source is used, which is the primary and Secondary elements replaced.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine nichtwechselbare Energiequelle eingesetzt wird. Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die von der Fahrradlichtmaschine erzeugte Wechselspannung über eine Diode gleichgerichtet wird und über einen Spannungs­ regler einen Kondensator auflädt, ohne Leuchten der Leuchtdioden. This object is achieved in that a non-changeable energy source is used. According to the invention the object is achieved in that the AC voltage generated by the bicycle alternator a diode is rectified and across a voltage regulator charges a capacitor without lighting the LEDs.  

Im Stand wird die Leuchtdiode über einen Widerstand und npn-Schalttransistor vom Elektrolytgoldkondensator für einige Minuten mit Strom versorgt.In the stand, the light emitting diode is connected via a resistor and npn switching transistor from the electrolytic gold capacitor for powered for a few minutes.

Die Erfindung wird nachstehend an einem Ausführungsbeispiel näher erläutert.The invention is illustrated below using an exemplary embodiment explained in more detail.

Die von der Fahrradlichtmaschine erzeugte Wechselspannung wird über die Diode 1 gleichgerichtet, über den Spannungs­ regler 3 stabilisiert und dem Kondensator 5 zugeführt. Bei fehlender Wechselspannung wird der pnp-Schalttran­ sistor 9 über die Widerstände 7, 8 durchgesteuert und schaltet über den Widerstand 10 die Leuchtdiode 11 ein. Da die Leuchtdiode bei laufender Fahrradlichtmaschine nicht leuchten soll, wird die von der Fahrradlichtmaschine kom­ mende Wechselspannung über die Diode 2 gleichgerichtet und über den Elektrolytgoldkondensator 6 geglättet und sperrt damit den pnp-Schalttransistor 9.The AC voltage generated by the bicycle alternator is rectified via the diode 1 , stabilized via the voltage regulator 3 and supplied to the capacitor 5 . In the absence of AC voltage, the pnp-Schalttran sistor 9 is turned on via the resistors 7 , 8 and turns on the light emitting diode 11 via the resistor 10 . Since the light emitting diode should not light up when the bicycle alternator is running, the alternating voltage coming from the bicycle alternator is rectified via the diode 2 and smoothed via the electrolytic gold capacitor 6 and thus blocks the pnp switching transistor 9 .
