Description

Blinklampenaqqreqat Flashing light aqqreqat
Die Erfindung betrifft ein Blinklampenaggregat mit einem elektrischen Speicher, z.B. einer Batterie zur Ener¬ gieversorgung der Lampe.The invention relates to a turn signal lamp unit with an electrical store, e.g. a battery for energy supply to the lamp.
Es ist bekannt, Baustellen und Absperrungen mit Blink- lampenaggregaten abzusichern. Diese Blinklampenaggregate sind mit Einweg-Batterien ausgestattet, welche periodisch, mindestens binnen 10 bis 20 Tagen ausgewechselt werden müs¬ sen. Diese Auswechselung ist mit hohen Kosten, wie Ar¬ beitsaufwand, Batterienachschaffung und deren Entsorgung, verbunden. Außerdem besteht die Gefahr, daß bei Erlöschen der Blink'lampe durch nicht rechtzeitiges Erneuern der Batte¬ rien, also durch Nachlässigkeit des Bedienungspersonals, die Baustellen ungesichert sind und somit Unfälle passieren können. Die Erfindung zielt darauf ab, hier Abhilfe zu schaf¬ fen und schlägt vor, daß bei einem Blinklampenaggregat der eingangs erwähnten Art zur Ladung des elektrischen Spei¬ chers, der bevorzugt als wiederaufladbarer Akkumulator aus¬ gebildet ist, ein Photoelement (Solargenergenerator) vorge- sehen ist, das integrierter Bestandteil des Blinklampen¬ aggregates ist. Dadurch, daß die Energieversorgung mit pho- tovoltaischen Elementen erfolgt und damit direkt aus dem Ta¬ geslicht der nötige Energiebedarf für die in dem Aggregat befindlichen aufladbaren Akkus gedeckt wird,ist sicherge- stellt, daß während der Dunkelheit die für den Betrieb des Aggregates erforderliche Energie zur Verfügung steht.It is known to secure construction sites and barriers with flashing lamp units. These flashing lamp units are equipped with disposable batteries which have to be replaced periodically, at least within 10 to 20 days. This replacement is associated with high costs, such as labor, replacement batteries and their disposal. There is also the risk that if the flashing lamp goes out due to the batteries not being replaced in time, that is to say due to carelessness of the operating personnel, the construction sites are unsecured and accidents can therefore occur. The invention aims to remedy this and proposes that a photo element (solar generator) be provided for a flashing lamp unit of the type mentioned at the beginning for charging the electrical memory, which is preferably designed as a rechargeable battery is, which is an integral part of the Blinklampen¬ unit. The fact that the energy supply takes place with photovoltaic elements and thus directly covers the necessary energy requirement for the rechargeable batteries located in the unit, ensures that the energy required for operating the unit during darkness is available.
In weiterer Ausgestaltung des erfindungsgemäßen Blink¬ lampenaggregates ist vorgesehen, daß das Photoelement nach Erreichen eines vorgegebenen, bevorzugt einstellbaren, unte- ren Schwellenwertes der PhotoSpannung, den Einschalter der Blinklampe betätigt. Dadurch wird automatisch sicherge¬ stellt, daß bei beginnender Dunkelheit, die sich ja in ei¬ nem Abfall der vom Photoelement gelieferten Spannung bzw. Leistung äußert, das Einschalten des Blinklampenaggregates (über die nunmehr höhere Spannung an den elektrischen Spei¬ cherelementen ) selbsttätig erfolgt. Es ist jedoch zusätz¬ lich zur oder statt der vorstehend erwähnten Maßnahme auch möglich, gemäß einer Weiterbildung der Erfindung, im Ein¬ schaltkreis der Lampe einen EIN/AUS Schalter anzuordnen, der durch Funksignale, insbes. codierte Funksignale, ei¬ nes Senders, z.B. eines Rundfunksenders ansteuerbar ist. Je nachdem, ob dieser EIN/AUS Schalter in Serie oder paral¬ lel zu dem in Abhängigkeit vom Schwellenwert der von dem Photoelement gelieferten Spannung betätigten Einschalter liegt, bedarf es zusätzlich der Funksignale zum Einschalten des Aggregates oder kann das Aggregat auch alternativ nur durch Funksignale eingeschaltet werden, unabhängig von der gelieferten Spannung des Photoelementes. Die Fernbedienung erlaubt eine individuelle Anpassung der Tätigkeit des Blinklampenaggregates an die jeweiligen Gegebenheiten - (z.B. höhere Lichtleistung in verkehrsreichen Zeiten, insbeson- dere durch Zuschalten weiterer Aggregate) und damit einen sparsamen Umgang mit der im Speicher vorhandenen Energie. Auch eine Noteinschaltung kann dadurch ermöglicht werden.In a further embodiment of the flashing lamp unit according to the invention, it is provided that the photo element, after reaching a predetermined, preferably adjustable, lower threshold value of the photo voltage, actuates the switch of the flashing lamp. This automatically ensures that when the darkness begins, which manifests itself in a drop in the voltage or power supplied by the photoelectric element, the turn-on lamp unit is switched on automatically (via the now higher voltage on the electrical storage elements). However, it is in addition to or instead of the measure mentioned above It is possible, according to a development of the invention, to arrange an ON / OFF switch in the circuit of the lamp which can be controlled by radio signals, in particular coded radio signals, from a transmitter, for example a radio transmitter. Depending on whether this ON / OFF switch is in series or parallel to the on switch actuated as a function of the threshold value of the voltage supplied by the photoelement, the radio signals are additionally required to switch on the unit or, alternatively, the unit can only be switched on by radio signals regardless of the voltage supplied by the photo element. The remote control allows the activity of the flashing lamp unit to be individually adapted to the prevailing circumstances - (eg higher light output in busy times, in particular by switching on additional units) and thus economical use of the energy in the storage. An emergency switch-on can also be made possible.
Um eine Überladung des elektrischen Speichers und auch eine unerwünschte Überladung des elektrischen Speichers über an den Speicher -angeschlossene Schaltkreise (z.B. den Takt¬ geber der Blinklampe, oder den Funksignalempfänger) zu ver¬ meiden, ist ein Laderegelungskreis in das Blinklampenagg¬ regat integriert. Ein Tiefentladeschutz ist jedoch nur bei bestimmten elektrischen Energiespeichern erforderlich. Bei Verwendung anderer elektrischer Energiespeicher kann ein Tiefentladeschutz entfallen.In order to avoid overcharging the electrical memory and also undesired overloading of the electrical memory via circuits connected to the memory (e.g. the clock of the flashing lamp or the radio signal receiver), a charge control circuit is integrated in the flashing lamp unit. However, deep discharge protection is only required for certain electrical energy stores. If other electrical energy storage devices are used, deep discharge protection can be dispensed with.
Weiterer Erfindungsgegenstand ist die Verwendung des erfindungsgemäß ausgebildeten Blinklampenaggregates zur Absicherung von Baustellen, insbes. Straßenbaustellen. Die Erfindung wird nachstehend anhand der Zeichnung, beispielsweise näher erläutert.

In der Zeichnung ist mit 1 die als Photoelement (Solar¬ generator) ausgebildete Energiequelle für die Ladung eines elektrischen Speichers 6 für den Betrieb einer elektrischen Glühlampe 3 bezeichnet, die. in einem durchsichtigen, z.B. gelben Lampengehäuse 2 angeordnet ist. Das Lampengehäuse 2 ist fest mit dem Lampenfuß 5 verbunden. Das Photoelement 1 steht über eine Sperrdiode 11 mit einem Laderegler 7 für den elektrischen Speicher in Verbindung. Der Glühlam¬ pe 3 vorgeschaltet ist ein Taktgeber 8, der hinsichtlich seiner Taktfrequenz bevorzugt regelbar ist. Hiezu ist ein an den Taktgeber 8 und den elektrischen Speicher 6 ange¬ schlossener Taktregler 12 vorgesehen. An dem Taktgeber 8 liegt weiters ein Empfänger 9 für Funksignale, in dessen zum Taktgeber 8 führendem Kreis ein Decoder 10 für die Funksignale eingeschaltet ist. Der Decoder 10 prüft die vom Empfänger 9 kommenden Signale auf richtige Codierung und gibt nur dann einen Einschaltimpuls an den Takgeber 8, wenn die Codierung für richtig befunden wurde. Im Taktge¬ ber 8 integriert ist auch ein (nicht dargestellter) Schal¬ ter, der den vom elektrischen Speicher 6 gespeisten Versor¬ gungskreis schließt, sobald die von dem Photoelement 1 ge¬ lieferte Spannung unter einen Schwellenwert fällt. Die Spannung des Speichers 6 übersteigt in einem solchen Fall die vom Photoelement 1 gelieferte Ladespannung. Die Elemen¬ te 7 bis 12 können auf einer Platine 4 angeordnet werden, die leicht zugänglich, zwecks Austauschens im Fuß 5 des Blinklampenaggregates angeordnet sein kann.
