Abstract
Description
Gasentladungslampen mit elektronischen Vorschaltgeräten werden bevorzugt wegen des geringen Stromverbrauches gegenüber herkömmlichen Glühlampen bei gleicher Lichtausbeute eingesetzt. Beispielsweise kann man bei Leuchtstofflampen mit etwa 20% Stromverbrauch die gleiche Lichtausbeute erzielen.Gas discharge lamps with electronic ballasts are preferred over the low power consumption conventional light bulbs used with the same light output. For example, with fluorescent lamps with about 20% Power consumption achieve the same luminous efficiency.
In vielen Fällen werden zusätzlich sog. "Dimmer" verwendet, um die Helligkeit der Lampen zu reduzieren. Dieser Wunsch be steht nicht nur, um zusätzlich Energie zu sparen, sondern auch um eine reduzierte Beleuchtungsstärke z. B. in den Nachtstunden einzustellen.In many cases, so-called "dimmers" are also used, to reduce the brightness of the lamps. This wish be stands not only to save additional energy, but also to a reduced illuminance z. B. at night adjust.
Solche Dimmer sind aufwendig und erfordern eine zusätz liche Installation, vor allem wenn sie nachträglich in ein vor handenes Beleuchtungssystem eingefügt werden sollen. Die Erfin dung hat die Aufgabe, in einfacher Weise neben einer maximalen Lichtstärke eine reduzierte Lichtstärke wählen zu können.Such dimmers are complex and require an additional one installation, especially when retrofitted into a pre existing lighting system to be inserted. The Erfin manure has the task, in a simple manner, in addition to a maximum Luminous intensity to be able to choose a reduced luminous intensity.
Erfindungsgemäß wird das dadurch erreicht, daß im Strom kreis ein bistabiles Umschaltsystem (Flip-Flop) vorhanden ist, welches beim Einschalten der Lampe in einen ersten Schaltzustand und bei einer kurzen Unterbrechung des Stromkreises in einen zweiten Schaltzustand gelangt, und sofort bei jeder kurzen Strom unterbrechung tritt also ein Wechsel zwischen den beiden Schalt zuständen auf. According to the invention this is achieved in that in the stream there is a bistable switching system (flip-flop), which when switching on the lamp in a first switching state and in the event of a short circuit break into one second switching state arrives, and immediately with every short current interruption occurs a change between the two switching states on.
Erfindungsgemäß entsprechen die beiden Schaltzustände ver schiedenen Lampenströmen und somit verschiedenen Helligkeits werten.According to the two switching states correspond to ver different lamp currents and thus different brightness evaluate.
Bei einer längeren Unterbrechung des Stromes z. B. über eine Sekunde schaltet das bistabile Umschaltsystem wieder in den Ausgangszustand zurück.With a longer interruption of the current z. B. about the bistable switching system switches back into the for one second Initial state back.
Ein solches Flip-Flop-System kann in einfacher Weise vor teilhaft im elektronischen Vorschaltgerät untergebracht werden.Such a flip-flop system can be done in a simple manner partially housed in the electronic ballast.
Da normalerweise beim Einschalten die größere Helligkeit erwünscht ist, wird erfindungsgemäß empfohlen, daß immer beim Einschalten der maximale Stromwert erreicht wird und eine Re duzierung erst mit einer kurzen Stromunterbrechung eingeschal tet wird.Because normally the greater brightness when switching on is desired, it is recommended according to the invention that always at Turn on the maximum current value is reached and a re reduction only with a short power interruption is tested.
Je nach Bedarf sind oft verschiedene reduzierte Stromwerte erwünscht. Daher wird erfindungsgemäß vorgesehen, daß ein Regel element vorhanden ist, mit dem der reduzierte Stromwert ein stellbar ist.There are often various reduced current values depending on the need he wishes. It is therefore provided according to the invention that a rule element is present with which the reduced current value is adjustable.
Aus Einsparungsgründen wird auch empfohlen, daß ein bi stabiles Umschaltsystem mehrere elektronische Vorschaltgeräte in Gruppen steuert.For reasons of savings, it is also recommended that a bi stable switching system several electronic ballasts controls in groups.
Bei größeren Anlagen ist es auch u. U. erwünscht, bei in Gruppen gesteuerten Vorschaltgeräten die reduzierten Stromwer te einzeln oder in Gruppen mit Regelelementen einstellbar zu machen.With larger systems it is also possible. U. desired at Group controlled ballasts the reduced Stromwer can be set individually or in groups with control elements do.
Um ein kurzzeitiges Erlöschen der Lampen beim Umschalten auf den zweiten Schaltzustand zu vermeiden, wird erfindungs gemäß ferner vorgeschlagen, einen Kurzzeitschalter, z. B. in form einer Drucktaste in den Stromkreis zu legen, der so kurz zeitig unterbricht, daß die Lampe nicht erlöscht, aber das bi stabile Umschaltsystem auf die Unterbrechung anspricht. For a brief extinction of the lamps when switching over to avoid the second switching state is fiction further proposed according to a short-time switch, for. B. in form a push button in the circuit that is so short interrupts at an early stage that the lamp does not go out, but the bi stable switching system responds to the interruption.
Fig. 1 zeigt eine beispielsweise Ausführung in schemati scher Darstellung, wie eine erfindungsgemäße Einrichtung auf gebaut sein könnte. Fig. 1 shows an example embodiment in schematic representation how a device according to the invention could be built on.
Die Gasentladungslampe (1) wird über ein elektronisches Vorschaltgerät an das Netz (R, S) angeschlossen. Dazwischen liegt das bistabile Umschaltsystem (6) und ein Lichtschalter (B), mit dem die Lampe (1) eingeschaltet werden kann. Sobald nach einem ersten Einschalten der Schalter (B) kurzzeitig ge öffnet wird, schaltet das bistabile Umschaltsystem in seine zweite Schaltlage und beeinflußt damit über das elektronische Vorschaltgerät (2) den Lampenstrom durch die Lampe (1).The gas discharge lamp ( 1 ) is connected to the network (R, S) via an electronic ballast. In between is the bistable switching system ( 6 ) and a light switch (B) with which the lamp ( 1 ) can be switched on. As soon as the switch (B) is opened briefly after the first switch-on, the bistable switching system switches to its second switching position and thus influences the lamp current through the lamp ( 1 ) via the electronic ballast ( 2 ).
Um eine sichtbare störende Unterbrechung des Lichtes zu vermeiden oder zumindest zu reduzieren, ist in der Zuleitung (R) ein Kurzzeitunterbrecher (13) angeordnet, der z. B. als Drucktaste ausgeführt sein kann. Wird diese Taste (13) betätigt, so erfolgt eine Stromunterbrechung im Millisekundenbereich, kurz genug, um ein störendes Erlöschen der Lampe (1) zu vermeiden, aber lang genug, um das bistabile Umschaltsystem (6) ansprechen zu lassen.In order to avoid or at least reduce a visible disturbing interruption of the light, a short-term interrupter ( 13 ) is arranged in the feed line (R). B. can be designed as a push button. If this button ( 13 ) is pressed, the power is interrupted in the millisecond range, short enough to prevent the lamp ( 1 ) from going out, but long enough to trigger the bistable switching system ( 6 ).
Um die reduzierte Helligkeit der Lampe (1) einstellen zu können, ist ein Regelelement (10) vorgesehen, welches in Art eines "Dimmers" den Lampenstrom wunschgemäß reduziert.In order to be able to set the reduced brightness of the lamp ( 1 ), a control element ( 10 ) is provided, which reduces the lamp current as desired in the manner of a "dimmer".
Fig. 2 zeigt eine Gruppenanordnung mit beispielsweise 3 Lampen (1), welche von den elektronischen Vorschaltgeräten (3, 4 und 5) versorgt werden. Das bistabile Umschaltsystem (7) beaufschlagt alle 3 elektronischen Vorschaltgeräte (3, 4 und 5), hingegen ist für das elektronische Vorschaltgerät (3) ein ge trenntes Regelelement (11) zur Einstellung der reduzierten Helligkeit vorgesehen. Fig. 2 shows a group arrangement with, for example, 3 lamps ( 1 ), which are supplied by the electronic ballasts ( 3 , 4 and 5 ). The bistable switching system ( 7 ) acts on all 3 electronic ballasts ( 3 , 4 and 5 ), however, a separate control element ( 11 ) is provided for setting the reduced brightness for the electronic ballast ( 3 ).
Das Regelelement (12) beaufschlagt hingegen als Gruppe die elektronischen Vorschaltgeräte (4 und 5). The control element ( 12 ), however, acts as a group on the electronic ballasts ( 4 and 5 ).
Die beiden beschriebenen Anordnungsbeispiele können natur gemäß beliebig variiert werden, insbesondere wenn z. B. das bi stabile Umschaltsystem (6, 7) in die elektronischen Vorschaltge räte (2, 3, 4, 5) oder in eines derselben integriert werden kann.The two arrangement examples described can of course be varied as desired, especially if, for. B. the bi stable switching system ( 6 , 7 ) in the electronic Vorschaltge devices ( 2 , 3 , 4 , 5 ) or in one of the same can be integrated.
Auch die Regelelemente (10, 11, 12) könnten in den elektro nischen Vorschaltgeräten integriert werden.The control elements ( 10 , 11 , 12 ) could also be integrated in the electronic ballasts.
Die angegebenen Anordnungen sind schaltungstechnisch belie big zu variieren, soweit sie den beschriebenen Zweck erfüllen.The specified arrangements are circuit-wise big to vary as far as they serve the purpose described.
Besondere Bedeutung kommt der Verwendung der Erfindungsidee Leuchtstofflampen zu, da diese Lampen normalerweise nicht über "Dimmer" oder ähnliche Maßnahmen in ihrer Helligkeit beeinflußt werden können.The use of the inventive idea is of particular importance Fluorescent lamps too, as these lamps usually don't have "Dimmer" or similar measures affect their brightness can be.
