Abstract
Description
Die vorliegende Erfindung betrifft Brandnotleuchten mit Fluchtwegkennzeichnungen, die insbesondere für Tunnels geeignet sind.The present invention relates to emergency lights with escape route markings, which are particularly suitable for tunnels.
Brandnotleuchten mit Fluchtwegkennzeichnungen sollen dazu dienen, im Notfall der Person anzugeben, welcher der nächste Notausgang im Tunnel ist und sollen darüber hinaus auch eine Beleuchtung des Tunnels und damit des Fluchtwegs sicherstellen.Fire emergency lights with escape route markings are intended to indicate in an emergency the person who is the nearest emergency exit in the tunnel and are also to ensure lighting of the tunnel and thus the escape route.
Herkömmliche Brandnotleuchten weisen ein Gehäuse zur Aufnahme von Leuchtmitteln, einen Deckel, der eine Sicherheitsscheibe aufweist, auf der Fluchtsymbole angebracht sind und die an ihrer Rückseite von einem Leuchtmittel beleuchtet wird. Die rückseitige Beleuchtung dieser Scheibe erfolgt mittels Glühlampe oder Energiesparlampe, wobei die Lampe ständig leuchtet. Weiterhin ist eine Brandnotleuchteneinrichtung vorgesehen, die im Brandfall leuchtet und einen Leuchtkegel von einer in der entsprechenden Norm festgelegten Größe erzeugt. Typischerweise weist die Brandnotleuchte einen 150 W-Halogenstrahler auf, der die Norm mit I(α) ≥25 cd für α -87° < α < +87 ° erfüllen muss. Damit dieser Leuchtkegel oder Leuchtbereich verwirklicht wird, muss die Sicherheitsglasscheibe für die Brandnotleuchte im Bereich der Brandnotleuchte nach außen gewölbt sein.Conventional emergency lights have a housing for receiving bulbs, a lid having a safety disc on which escape symbols are mounted and which is illuminated at its rear by a light source. The rear lighting of this disc is done by means of incandescent or energy saving lamp, the lamp is constantly lit. Furthermore, a fire alarm device is provided which lights up in the event of fire and generates a light cone of a specified size in the corresponding standard. Typically, the emergency lighting fixture has a 150 W halogen spotlight that must meet the standard with I (α) ≥25 cd for α -87 ° <α <+87 °. For this light cone or light area is realized, the safety glass for the emergency light must be arched outward in the area of the emergency light.
Diese herkömmlichen Brandnotleuchten weisen deutliche Nachteile auf. Fällt die Glühlampe oder Energiesparlampe zur Beleuchtung der Fluchtwegkennzeichnungen aus, so werden die Fluchtwegekennzeichnungen nicht mehr beleuchtet und sind sie damit nicht mehr oder nur ganz schlecht sichtbar, was im Notfall entsprechende Konsequenzen haben kann.These conventional emergency lights have significant disadvantages. If the incandescent lamp or energy-saving lamp fails to illuminate the escape route markings, the escape route identifiers are no longer illuminated and are thus no longer or only very badly visible, which can have corresponding consequences in an emergency.
Die Ausbildung einer gewölbten oder bombierten Sicherheitsscheibe ist eine teure Spezialanfertigung, die die Brandnotleuchte insgesamt teuer macht. Weiterhin fällt bei Ausfall des 150 W-Halogenstrahlers die gesamte Brandnotleuchteneinrichtung aus.The formation of a domed or domed safety disc is an expensive custom-made, which makes the emergency light altogether expensive. Furthermore, if the 150 W halogen radiator fails, the entire fire alarm system will fail.
Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, eine Brandnotleuchte mit Fluchtwegkennzeichnungen, die insbesondere für Tunnels geeignet ist, vorzuschlagen, bei der die oben erwähnten Nachteile überwunden sind, und die eine einfach und wirksam aufgebaute Brandnotleuchte, insbesondere mit erhöhter Ausfallsicherheit, schafft.The present invention is therefore based on the object, an emergency lighting with escape route markings, which is particularly suitable for tunnels to propose, in which the above-mentioned disadvantages are overcome, and which creates a simple and effective fire emergency, especially with increased reliability.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is solved by the features of patent claim 1.
Dadurch, dass die Leuchtmittel zur Beleuchtung der Sicherheitsglasscheibe aus einer Mehrzahl von Leuchtdioden gebildet ist, wird nicht nur eine kostengünstige Beleuchtung der Fluchtwegkennzeichnungen erreicht, sondern auch vermieden, dass bei Ausfall einzelner Leuchtdioden die Beleuchtung der Sicherheitsglasscheibe und damit der Fluchtwegkennzeichnungen weiterhin vorhanden ist. Insbesondere liegt der Vorteil einer LED-Beleuchtung an einer bis zu zehnmal längeren Lebensdauer des Leuchtmittels und damit auch an einem erheblich längeren Wartungszyklus für die Einrichtung. Der Vorteil lässt sich insbesondere dadurch abschätzen, dass Reparaturarbeiten in Tunnels zu erheblichen Verkehrsbehinderungen führen können und deshalb so weit wie möglich vermieden werden sollen.The fact that the lighting means for illuminating the safety glass pane is formed from a plurality of light-emitting diodes, not only a cost-effective lighting of the escape route markings is achieved, but also avoided that in case of failure of individual LEDs, the lighting of the safety glass pane and thus the escape route markings is still present. In particular, the advantage of LED lighting is up to ten times longer life of the lamp and thus a much longer maintenance cycle for the device. The advantage can be estimated in particular by the fact that repair work in tunnels can lead to considerable traffic obstructions and should therefore be avoided as far as possible.
Dadurch, dass die Brandnotleuchte aus einer Mehrzahl von Halogenstrahlern gebildet ist, die im Betrieb den geforderten Leuchtkegel bzw. Leuchtbereich erzeugen, wird erreicht, dass keine zusätzlichen Maßnahmen, wie das Wölben beziehungsweise Bombieren der Sicherheitsscheibe notwendig ist. Wiederum bietet sich hier auch der Vorteil, dass bei Ausfall einzelner Halogenstrahler die verbleibenden Halogenstrahler weiterhin die Funktion der Brandnotleuchte, wenn auch in verringertem Maße, erfüllen können, wohingegen bei Ausfall des einzelnen Halogenstrahlers im Stand der Technik die Funktion der Brandnotleuchte ausfällt.The fact that the emergency light is formed from a plurality of halogen lamps that generate the required light cone or light area during operation, it is achieved that no additional measures, such as buckling or crowning the safety glass is necessary. Again, here also offers the advantage that in case of failure of individual halogen lamps, the remaining halogen lamps continue to fulfill the function of emergency lighting, albeit to a lesser extent, whereas failure of the individual halogen lamps in the prior art, the function of the emergency lights fails.
Die Ausfallsicherheit der Leuchtmittel für die Fluchtwegkennzeichnungen wird vorteilhafterweise insbesondere dadurch erreicht, dass die Leuchtdioden so verschaltet angeordnet sind, dass beim Ausfall einer Leuchtdiode die restlichen Leuchtdioden weiterhin leuchten.The reliability of the light source for the escape route markings is advantageously achieved in particular by the fact that the LEDs are arranged so interconnected that the failure of a light emitting diode, the remaining LEDs continue to light.
Dabei wird eine gute Beleuchtung durch die Verwendung von Hochleistungs-Leuchtdioden erreicht.This will provide good lighting through the use of high power light emitting diodes reached.
Durch die Verwendung einer Konstantspannungsquelle für die Leuchtdioden ergibt sich der Vorteil, dass bei Netzspannungsschwankungen diese zu keiner Änderung der Leuchtdiodenhelligkeit führen und damit Netzspannungsschwankungen nicht sichtbar sind. Dies ergibt den Vorteil, dass kein Flackern bei den Fluchtwegkennzeichnungen auftritt, und somit jegliche Ablenkung und Verunsicherung der sich im Tunnel bewegenden Personen vermieden wird.By using a constant voltage source for the light-emitting diodes, there is the advantage that in the case of mains voltage fluctuations, these do not lead to a change in the brightness of the LEDs, and thus mains voltage fluctuations are not visible. This provides the advantage that no flicker occurs in the escape route markings, and thus any distraction and uncertainty of moving in the tunnel people is avoided.
Vorteilhafterweise sind fünf Halogenstrahler vorgesehen, die so angeordnet sind, dass sie einen Leuchtkegel mit einem Winkel von 180° erzeugen. Dies übererfüllt nicht nur die oben angegebene Norm sondern ist die 40°-Abstrahlcharakteristik dieser Halogenstrahler als Orientierungsstrahl im Rauch auch deutlich besser sichtbar. Vorteilhafterweise werden statt dem 150 W-Halogenstrahler des Standes der Technik fünf einzelne 20 W-Halogenstrahler mit einem Durchmesser von jeweils 50 mm verwendet.Advantageously, five halogen lamps are provided, which are arranged so that they produce a light cone with an angle of 180 °. This not only exceeds the above-mentioned standard but is the 40 ° radiation characteristic of these halogen lamps as orientation beam in the smoke also much better visible. Advantageously, instead of the 150 W halogen spotlight of the prior art, five individual 20 W halogen lamps with a diameter of 50 mm each are used.
Weiterhin ist von Vorteil, dass der Deckel mit integrierter Sicherheitsscheibe aus Edelstahl gebildet ist und so an dem Gehäuse angebracht ist, dass er durch Entriegelung eines Schlosses mittels Sicherheitsschlüssel oder Vierkantöffner entfernt werden kann. Dies verhindert ein umständliches und damit zeitintensives Entfernen des Deckels zu Wartungszwecken, insbesondere zum Ersetzen ausgefallener Leuchtmittel, was, wie bereits oben erwähnt, in einem Tunnel von besonderer Wichtigkeit ist.Furthermore, it is advantageous that the lid is formed with integrated safety disc made of stainless steel and is attached to the housing so that it can be removed by unlocking a lock using security key or square opener. This prevents a cumbersome and thus time-consuming removal of the cover for maintenance purposes, in particular for replacing failed bulbs, which, as already mentioned above, in a tunnel is of particular importance.
Vorteilhafterweise ist der Deckel pyramidenstumpfförmig aufgebaut, das heißt seine vier Seitenwände vergrößern sich von der Frontscheibe in Richtung Gehäuse, wodurch scharfe Kanten an der Frontseite vermieden werden.Advantageously, the lid is constructed in the shape of a truncated pyramid, that is to say its four side walls increase in size from the front pane in the direction of the housing, as a result of which sharp edges on the front side are avoided.
Weiterhin ist vorteilhaft, dass Leuchtdiodenstreifen vorgesehen sind, die seitlich am pyramidenstumpfförmigen Deckel der Brandnotleuchte angebracht sind. Das Netzteil für diese LED-Streifen befindet sich im Gehäuseinnenteil. Sobald der Deckel mit dem Gehäuse verbunden wird, werden auch die Steckkontakte von Deckel und Gehäuse miteinander verbunden über welche die LED-Spannung vom Netzteil zu den LED-Streifen geführt wird.Furthermore, it is advantageous that light emitting diode strips are provided, which are mounted laterally on the truncated pyramid lid of the emergency light. The power supply for these LED strips is located inside the housing. As soon as the cover is connected to the housing, the plug contacts of the cover and housing are also connected to each other via which the LED voltage from the power supply to the Led strip is led.

Bezugnehmend auf Fig. 2 ist dort in Teilansicht ein Gehäuse 31 der Brandnotleuchte 1 ohne Deckel 3 dargestellt. Auf einer Montageplatte 33 sind fünf Halogenstrahler 21 angeordnet, wobei sie jeweils unter einem bestimmten Winkel zueinander angeordnet sind, wodurch ein Gesamtlichtkegel mit einem Winkel α von +90° und -90° erreicht wird. Wie aus Fig. 2 ersichtlich, ist der mittlere Halogenstrahler auf einer optischen Achse X ausgerichtet, die im Wesentlichen senkrecht zur Frontseite der Brandnotleuchte verläuft. Der unmittelbar davon links und der unmittelbar davon rechts angeordnete Halogenstrahler ist unter einem Winkel β von ca. 35° zur optischen Achse X angeordnet. Die beiden äußeren Halogenstrahler sind jeweils unter einem Winkel γ von ca. 20° angeordnet, wobei der Winkel γ zwischen der optischen Achse X2 des Halogenstrahlers und der Senkrechten zur optischen Achse X aufgespannt ist.Referring to FIG. 2, there is shown in partial view a

Wie weiterhin ersichtlich, sind die Halogenstrahler 21 nach leichtem Entfernen des Deckels 3 unmittelbar zugänglich und können bei Ausfall entsprechend schnell ausgewechselt werden, indem sie aus ihren jeweiligen Fassungen 22 leicht entfernbar und durch neue Halogenstrahler 21 ersetzbar sind.As can further be seen, the
In Fig. 3 ist eine Montageplatte 35 gezeigt, in der Hochleistungs-Leuchtdioden 37, insgesamt 12 an der Zahl, sowohl an den vier Eckpunkten der Montageplatte 35 als auch in einer kreisförmigen Anordnung um das Zentrum der Montageplatte 35 herum angeordnet sind. Die Leuchtdioden 37 sind dabei so geschaltet, dass bei Ausfall einer Leuchtdiode die anderen Leuchtdioden weiter in Betrieb sind.In Fig. 3, a
Die Leuchtdioden 37 werden über Leitungen 39 mit Strom von einer Konstantspannungsquelle (nicht dargestellt) versorgt, wodurch sichergestellt wird, dass Netzspannungsschwankungen keine Schwankungen in der LED-Helligkeit erzeugen.The light emitting diodes 37 are supplied with power from a constant voltage source (not shown) via lines 39, thereby ensuring that line voltage variations do not produce variations in LED brightness.
Mit der vorliegenden Erfindung wird somit eine Brandnotleuchte mit Fluchtwegkennzeichnungen geschaffen, bei der vorteilhafterweise eine einfachere und billigere Ausgestaltung als bei Brandnotleuchten des Standes der Technik erreicht wird, und insbesondere nicht nur eine erheblich längere Lebensdauer der konstanten Fluchtwegkennzeichnungsbeleuchtung und damit erheblich geringere Wartungsarbeiten an den Leuchten erreicht wird, sondern auch durch die Mehrzahl an Halogenstrahlern eine größere Ausfallsicherheit der Brandnotleuchten selbst, und eine bessere, sowohl breitere als auch intensivere Beleuchtung des Tunnels im Brandfall erreicht wird.The present invention thus provides an emergency exit light with escape route markings which advantageously achieves a simpler and cheaper design than prior art emergency lights, and in particular not only achieves a significantly longer life of the constant escape route marker lighting and thus significantly reduces maintenance on the lights is, but also by the majority of halogen lamps greater reliability of the emergency lights themselves, and a better, both wider and more intense illumination of the tunnel in case of fire is achieved.
