Description
Titel: starterlosex Betrieb von (techn.bezeichnung) Leuchtstofflampen an Wechselstromnetzen m.H. von Spannungsvervielfachung Anwendungsgebiet: Die Erfindung betrifft Leuchtstofflampen die eigentlich für das Glimmstarterprinzip vorgesehen sind.Title: starterlosex operation of (technical designation) fluorescent lamps on alternating current networks mH of voltage multiplication Area of application: The invention relates to fluorescent lamps which are actually intended for the glow starter principle.
Da bei Beuchtstofflampen in kaltem Zustand die Zündspannung größer als die Betriebsspannung ist,müssen zuerst nach dem I;inschalten die Elektroden m.H. eines Glimmstarters aufgeheizt werden. Because fluorescent lamps have a higher ignition voltage when they are cold than the operating voltage, the electrodes must first be switched on after the I; m.H. a glow starter.
Bei dieser Betriebsweise leuchtet die Lampe erst einige Sekunden nach dem Einschalten Die unterschiedliche Wärmeträgheit von den Leuchtstofflampenelektroden und dem Glimmstarter führt zu einem Flackern- in der Einschaltphase. In this mode of operation, the lamp only lights up for a few seconds after switching on The different thermal inertia of the fluorescent lamp electrodes and the glow starter leads to a flickering in the switch-on phase.
Werner tritt ein höherer Einschaltstrom im Vergleich zum Betriebsstrom auf. Werner occurs a higher inrush current compared to the operating current on.
Zweck Leuchstofflampen in kaltem Zustand zu zünden und zu betreiben. Purpose to ignite and operate fluorescent lamps when they are cold.
Leuchtstofflampen,dle bisher für Starterbetrieb vorgesehen waren, können -ohne Starterunverändert für die neur Lösung verwendet werden. Fluorescent lamps that were previously intended for starter operation, can be used unchanged for the new solution without a starter.
Lösung: Diese Aufgabe wird erfindungamäßig dadurch gelöst,daß eine Spannungsvervielfachungsschaltung angewendet wird,die eine Spannung größer als die Zündspannung in kaltem Zustand erzeugt. @@@@.Solution: This object is achieved according to the invention in that a Voltage multiplier circuit is applied, which has a voltage greater than that Ignition voltage generated in the cold state. @@@@.
Der Innenwiderstand der Spannungsvervielfachungsschaltung wird so hoch gewählt, daß in gezündetem Zustand,die Lampe mit ihrer Nennleistung betrieben wird. The internal resistance of the voltage multiplying circuit becomes like this chosen high that in the ignited state, the lamp operated with its rated power will.
Es tritt kein erhöhter Einschaltstrom auf. There is no increased inrush current.
Erzielbare Jorteile: a)Trägheitsarme Einschaltung Sekundenbruchteile im Gegensagz zu einigen Sekunden im Glimmstarterbetrieb.Achievable Jorteile: a) Low inertia activation fractions of a second in contrast to a few seconds in glow starter operation.
b)Optische Belästigung entfällt,da flackerfreier Einschaltvorgang. b) There is no visual annoyance as the switch-on process does not flicker.
c)Keine Funkenstörung. c) No spark interference.
i3eschreibung: Ein ivusführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird in folgenden naher beschrieben.Description: An example embodiment of the invention is shown in the drawing and is described in more detail below.
Zu Fig. 1 Leuchtstofflampe nicht gezündet: Die Gleichrichter Gl 1 u. 2 in Verbindung mit den Kondensatoren C 1 u. 2 bilden eine Spannunsverdopplungsschaltung. Die Gleichrichter Gl 3 u. 4 sind hierbei ohne Belang.For Fig. 1 fluorescent lamp not ignited: The rectifiers Gl 1 and 2 in connection with the capacitors C 1 and 2 form a voltage doubling circuit. The rectifiers Eqs 3 and 4 are irrelevant here.
(Betrieb in Sperrichtung) Maximal erreichbare Spannung Bei Erreichen der Zündspannung zündet die Leuchtstofflampe und die in C 1 u. C 2 gespeicherte Energie führt zu einer Lichbogenentladung.(Operation in reverse direction) Maximum attainable voltage When reached the ignition voltage ignites the fluorescent lamp and those in C 1 & C 2 stored energy leads to an arc discharge.
Leuchstofflampe in gezündetem Zustand: Dabei sind C 1 u. C 2 ohne Belang. Ignited fluorescent lamp: C 1 and C 2 are without Concern.
Die Gleichrichter G1 3 u. 4 werden wirksam und bilden zusammen mit G1 1 u. 2 eine Grätz-Brückenschaltung. The rectifiers G1 3 and 4 are effective and form together with G1 1 and 2 a Grätz bridge circuit.
Zu Fig. 2: Entsprechende Spannungsvervierfachung. To Fig. 2: Corresponding voltage quadrupling.
Spannungsverdreifashungsbetrieb auch möglich. Voltage tripling operation also possible.
Die Wahl der Schal@ung hängt von der erforderlichen Zündspannung ab. The choice of circuitry depends on the required ignition voltage away.
