Definitions
- the present invention relates to a signaling unit.
- Such signaling units are used especially in rail and road traffic as light signals.
- a conversion to low-maintenance light sources is therefore very expensive and causes high costs and would have to be made during the conversions in the signal boxes overnight.
- a safety inspection and an official operating license are generally required. The effort is very large. Elaborate conversions allow today very short rest intervals in the transport networks of only a few hours, usually after midnight. Economic criteria speak against it.
- a device When using double-filament lamps in a signal system designed for this purpose, a device switches automatically to the secondary eddy by breaking the main filament. In this case, however, due to the position of the auxiliary coil outside the focal point only a reduced light intensity in the main axis of the signal is achieved and the emission characteristic also changes according to the focal deviation. Electrically speaking, based on the monitoring circuit, however, there are no changes in the circuit parameters due to the helical switching, with the exception of the transient switching of transient artifacts. It should be emphasized here that filament lamps for signaling purposes (and that is the majority of many tracks) can not be replaced by double filament lamps. The reason for this are the different operating data of the incandescent lamps and thus the functional characteristics of the control units installed for single-filament lamps, which are not designed for controlling the two lamp filaments.
- a LED replacement light source in the lamp signal circuit parallel to the incandescent filament.
- This source can be synchronous be controlled simultaneously with the control of the lamp or this replacement light source is on cold redundancy and is switched at the time of helix failure in the circuit and takes over the triggered by the control part current flow in the control circuit, the light output of the signal.
- Such a light-emission substitute takes over in the event of failure of a single-filament or at most two-filament incandescent lamp an expedient substitution of the light source and thus avoids interruptions of the functionality of the signal and thus during operation. As a result, the timing of the repair of the signal much better planning than usual.
- the inventive approach assumes that the standard light source has, for example, a nominal power consumption of a typical signal lamp of 20 watts.
- the substitution light source together with its drive device, has a significantly lower power consumption.
- the light source monitoring dimensioned in terms of incandescent lamp characteristics in the associated control part is not able to recognize it as being functional on the basis of the monitored electrical parameters in accordance with the lower power consumption and thus the smaller current of the LED emitter.
- the Figures 1 and 2 each schematically show a light signal, in which in addition to the light bulb, an LED unit is provided to replace the bulb in the event of burning their filament.
- the LED unit is arranged directly behind the light bulb on the main light axis; in FIG. 2 The light of the LED unit is fed via a light guide behind the light bulb in the main light axis.
- an infrared filter to the light exit of the light guide to at least greatly attenuate a thermal feedback of the light bulb to the LED unit or the light guide.
- the luminous flux via an exit lens on the signal is given only by the solid angle detected by the exit lens. In other words, this means that a large part of the solid angle is black and thus absorbs the light radiation.
- Modern LED units with quasi punctiform light sources therefore achieve luminous fluxes of up to 100 lumens and more, which easily reach the luminosity of the incandescent lamp used in the signal at significantly lower power consumption.
- the current latest generation of LEDs now has a luminous efficacy of up to 100 lumens / watt.
- the incandescent lamp signals radiate in the required and common in the railway safety technology execution (avoidance of phantom light) only a relatively low luminous flux. This is calculated from the active solid angle (sterradiant) and the transmission of the color filter with a light source with white A 2856 ° K. For the signal color red, the 10 lumens are then emitted to the front. From these points of view, the luminous flux defined above must then be assessed.
- the whistle of the inventive solution is therefore seen to incorporate in signals with incandescent light source a redundant replacement light source in LED technology.
- the incandescent lamp is left unchanged in the defective state in the signal housing and is used in a suitable manner as an optical function part in the beam path of the then shining LED light source.
- the LED light source radiates directly into the main axis of the beam path from the glass bulb of the incandescent lamp directed forwardly against the light exit opening of the signal or uses a collimator for processing the radiation characteristics and / or a light guide for the supply of light to the appropriate point in the major axis.
- the glass bulb of the incandescent lamp is used as a kind of lens, which throws the light in a suitable manner forward on the front lens. It is thereby achieved at least approximately the same effect as is present through the helix in the focal point of the optics.
- FIGS. 3 and 4 now each show a schematic diagram for a light bulb insert with redundant LED unit; once for a light bulb with only one filament ( Fig. 3 ) and once for a light bulb with a double thread ( Fig. 4 ).

Abstract
Description
Die vorliegende Erfindung betrifft eine Signalisierungseinheit. Derartige Signalisierungseinheiten werden besonders im Schienen- und Strassenverkehr als Lichtsignale verwendet.The present invention relates to a signaling unit. Such signaling units are used especially in rail and road traffic as light signals.
Es sind sehr viele Lichtsignale in Verkehrsanlagen insbesondere in den Eisenbahnnetzen im Betrieb, welche mit Glühlampen als Lichtquellen ausgerüstet sind. Allein in der Schweiz dürften dies über 30'000 Lichtquellen sein. Die Signaltechnik im Verkehr basiert auf Stellteilen, welche die Signallampen mit genau definierten Betriebsparametern ansteuern. Zusätzlich werden dabei die Lichtquellen mittels Messung von vorbestimmten elektrischen Parametern, wie z.B. die Grösse des fliessenden Stroms im Lampenstromkreis, indirekt auf eine korrekte Lichtabgabe überwacht. Es gilt dabei in der Signalisieungstechnik die Annahme, dass Stromfluss durch eine Glühlampe gleichbedeutend mit Lichtabgabe ist. Glühlampen haben eine eingeschränkte Lebensdauer und fallen meist mit einem Durchbrennen / Durchschmelzen der Glühwendel mit dem folglichen Unterbruch des Stromkreises aus. Dadurch fällt die bestimmungsgemässe Funktion der optischen Anzeige, z.B. einer bahntechnischen Fahrtberechtigungs-Information (Signalbegriff) aus. Kritisch sind solche Ausfälle vor allem bei Haltbefehlen. Es wird je nach Funktion von Betriebshemmung und/oder dann von Betriebsgefährdung gesprochen. Dadurch ist für die Beseitigung dieses Zustandes kurzzeitig ein aktiver Einsatz von Wartungspersonal für den Austausch der defekten Lichtquelle erforderlich.There are a lot of light signals in traffic systems, especially in the railway networks in operation, which are equipped with incandescent lamps as light sources. In Switzerland alone, more than 30,000 light sources are expected to be. Signaling technology in traffic is based on actuators that control the signal lamps with precisely defined operating parameters. In addition, the light sources are measured by measuring predetermined electrical parameters, e.g. the magnitude of the flowing current in the lamp circuit, indirectly monitored for a correct light output. In signaling technology, the assumption is that current flow through an incandescent lamp is synonymous with the emission of light. Incandescent lamps have a limited life and usually fail with a burn through / melting of the filament with the subsequent interruption of the circuit. As a result, the intended function of the visual display, e.g. a railway driving authorization information (signal term) from. Such failures are critical, especially with stop commands. It is spoken depending on the function of operation inhibition and / or then from operational hazards. As a result, an active use of maintenance personnel for the replacement of the defective light source is briefly required for the elimination of this condition.
Will der Betreiber diese kurzfristigen Wartungseinsätze für den Austausch der Signale vermeiden, so liegt als Lösung der Austausch der Glühlampe gegen eine andere Technologie nahe. In der Signalisierungstechnik wird dies bereits mit der LED-Technik für Erstausrüstungen praktiziert. Doch die Funktionalität vieler im Betrieb stehender Lampenstellteile mit ihrer Stellwerkschnittstelle verlangen nach Glühlampensubstituten, die jedoch in der Regel vergleichsweise kostspielig sind. Für einfache Lösungen auf der Lichtquellenseite wären aufwendige Anpassungen an den (Überwachungs-)Anlagen erforderlich.If the operator wants to avoid these short-term maintenance interventions for the exchange of signals, the solution is to replace the incandescent lamp with another technology. In signaling technology this is already practiced with the LED technology for original equipment. But the Functionality of many operating in the lamp actuator parts with their interlocking interface require incandescent lamp substitutes, which, however, are usually relatively expensive. For simple solutions on the light source side would require extensive adjustments to the (monitoring) systems.
Primär ist es jedoch erforderlich, mittels der Überwachungseinrichtungen oder anderer Massnahmen die erforderliche sehr geringe Restfehler-Wahrscheinlichkeit im Sinne der Sicherheit (Safety) zu erreichen und zu gewährleisten.Primarily, however, it is necessary to achieve and ensure the required very low residual error probability in the sense of safety (safety) by means of the monitoring devices or other measures.
Eine Umrüstung auf wartungsarme Lichtquellen ist demzufolge sehr aufwendig und verursacht hohe Kosten und müsste bei den Umrüstungen in den Stellwerken über Nacht vorgenommen werden. Zudem sind generell nach solchen Eingriffen in eine Anlage vor Beginn der Nutzung der aufgerüsteten Funktionen eine Sicherheitsprüfung sowie eine behördliche Betriebsbewilligung erforderlich. Der Aufwand dabei ist sehr gross. Aufwendige Umbauten erlauben die heute sehr kurzen Ruheintervalle in den Verkehrsnetzen von nur einigen Stunden meist nach Mitternacht nicht mehr. Auch ökonomische Kriterien sprechen dagegen.A conversion to low-maintenance light sources is therefore very expensive and causes high costs and would have to be made during the conversions in the signal boxes overnight. In addition, after such operations on a facility prior to the start of the use of the upgraded functions, a safety inspection and an official operating license are generally required. The effort is very large. Elaborate conversions allow today very short rest intervals in the transport networks of only a few hours, usually after midnight. Economic criteria speak against it.
Es ist nun die Aufgabe der Erfindung, dass bei einem Ausfall einer Glühlampe ein Verfahren und eine Einrichtung diejenige Funktion übernehmen, welche den weiteren Betrieb ermöglicht und die Instandstellung, das heisst der Lampenwechsel im Signal, bis zu einigen Tagen hinausgeschoben werden kann. Der herkömmlich unmittelbare Einsatz für die Instandstellung entfällt somit. Damit werden auch die Risiken gegen körperliche Schäden beim Unterhaltspersonal stark vermindert.It is now the object of the invention that in case of failure of a light bulb, a method and a device take over that function which allows further operation and the maintenance, that is the lamp change in the signal, can be postponed up to several days. The conventional immediate use for the maintenance is thus eliminated. This also greatly reduces the risks of physical injury to maintenance staff.
Bevor die erfindungsgemässe Lösung vorgestellt wird, soll hier nachfolgend noch einmal der heutige Ist-Zustand zusammengefasst wieder gegeben werden. Ein Ausfall einer Glühlampe durch Wendelbruch wird durch das zugehörige Stellteil detektiert und eine entsprechende Fehlermeldung durch das Stellteil im Stellwerk (System) generiert. Diese im Stellwert registrierte Fehlermeldung wird nun in der dispositiven Ebene der Leittechnik durch die Fahrdienstleiter verarbeitet. Mit anderen Worten heisst dies, dass der Pikettdienst für Störungen aufgeboten wird, um die ausgefallene Lichtquelle zu ersetzen. Gleichzeitig werden bei Bedarf und soweit möglich die Fahrwege (Fahrstrassen) für die Züge angepasst, um die ausgefallene Signalstelle zu umfahren und damit Betriebshemmungen zu vermeiden. Diese Massnahme kann jedoch die Streckenkapazität entsprechend verringern, was netzbetreiberseitig unerwünscht, aber aus Sicherheitsüberlegungen absolut unerlässlich ist.Before the solution according to the invention is presented, the present state of affairs should be summarized here again below. A failure of an incandescent lamp by Wendelbruch is by the associated Detected control part and a corresponding error message generated by the control in the interlocking (system). This error message registered in the control value is now processed by the dispatcher in the dispatching level of the control technology. In other words, this means that the on-call service will be called in to replace the failed light source. At the same time, if necessary and as far as possible, the routes (routes) for the trains are adjusted in order to bypass the failed signal point and thus to avoid operational obstacles. However, this measure can reduce the line capacity accordingly, which is undesirable on the network operator side, but absolutely essential for safety reasons.
Beim Einsatz von Doppelfadenlampen in einem dafür konzipierten Signalsystem wird bei Bruch des Hauptwendels mittels einer Einrichtung selbsttätig auf den Nebenwedel umgeschaltet. Dabei wird jedoch infolge der Stellung des Nebenwendels ausserhalb des Brennpunktes nur eine verminderte Lichtstärke in der Hauptachse des Signals erreicht und die Abstrahlcharakteristik ändert sich ebenfalls entsprechend der Brennpunktabweichung. Elektrisch gesehen, bezogen auf die Überwachungsschaltung, ergeben sich dabei jedoch durch die Wendelumschaltung mit Ausnahme bei der Umschaltung kurzzeitig auftretender transienter Artefakte keine Änderungen der Stromkreis-Parameter. Es muss dabei hier hervorgehoben werden, dass Einfadenlampen für Signalisierungszwecke (und das ist die Majorität bei vielen Bahnen) nicht durch Doppelfadenlampen ersetzt werden können. Grund dafür sind die unterschiedlichen Betriebsdaten der Glühlampen und damit die funktionale Ausprägung der für Einfadenlampen installierten Stellteile, welche für eine Ansteuerung der zwei Lampenwendel nicht konzipiert sind.When using double-filament lamps in a signal system designed for this purpose, a device switches automatically to the secondary eddy by breaking the main filament. In this case, however, due to the position of the auxiliary coil outside the focal point only a reduced light intensity in the main axis of the signal is achieved and the emission characteristic also changes according to the focal deviation. Electrically speaking, based on the monitoring circuit, however, there are no changes in the circuit parameters due to the helical switching, with the exception of the transient switching of transient artifacts. It should be emphasized here that filament lamps for signaling purposes (and that is the majority of many tracks) can not be replaced by double filament lamps. The reason for this are the different operating data of the incandescent lamps and thus the functional characteristics of the control units installed for single-filament lamps, which are not designed for controlling the two lamp filaments.
Erfindungsgemäss ist es nun vorgesehen, im Lampensignalstromkreis parallel zum Glühwendel eine LED Ersatz-Lichtquelle zu betreiben. Diese Quelle kann synchron mit der Ansteuerung der Lampe gleichzeitig angesteuert werden oder diese Ersatzlichtquelle liegt auf kalter Redundanz und wird im Zeitpunkt des Wendelausfalls in den Stromkreis geschaltet und übernimmt beim durch das Stellteil ausgelösten Stromfluss im Ansteuerkreis die Lichtabgabe des Signals. Ein solches Licht-Emissionssubstitut übernimmt bei einem Ausfall einer Einwendel- oder allenfalls Zweiwendel- Glühlampe eine zweckmässige Substitution der Lichtquelle und vermeidet dadurch Unterbrüche der Funktionalität des Signals und somit im Betriebsablauf. Dadurch lässt sich der Zeitpunkt der Instandsetzung des Signals viel zweckmässiger als bisher üblich planen.According to the invention, it is now provided to operate a LED replacement light source in the lamp signal circuit parallel to the incandescent filament. This source can be synchronous be controlled simultaneously with the control of the lamp or this replacement light source is on cold redundancy and is switched at the time of helix failure in the circuit and takes over the triggered by the control part current flow in the control circuit, the light output of the signal. Such a light-emission substitute takes over in the event of failure of a single-filament or at most two-filament incandescent lamp an expedient substitution of the light source and thus avoids interruptions of the functionality of the signal and thus during operation. As a result, the timing of the repair of the signal much better planning than usual.
Der erfinderische Ansatz geht in einer ersten Variante davon aus, dass die Standardlichtquelle beispielhaft eine nominale Leistungsaufnahme einer typischen Signallampe von 20 Watt aufweist. Die Substitutionslichtquelle dagegen hat zusammen mit seiner Ansteuereinrichtung eine wesentlich geringere Leistungsaufnahme. Dadurch ist jedoch die auf Glühlampeneigenschaften dimensionierte Lichtquellenüberwachung im zugehörigen Stellteil nicht in der Lage, entsprechend der geringeren Leistungsaufnahme und damit dem kleineren Strom des LED Strahlers diesen anhand der überwachten elektrischen Parameter als funktionstüchtig zu erkennen.In a first variant, the inventive approach assumes that the standard light source has, for example, a nominal power consumption of a typical signal lamp of 20 watts. By contrast, the substitution light source, together with its drive device, has a significantly lower power consumption. As a result, however, the light source monitoring dimensioned in terms of incandescent lamp characteristics in the associated control part is not able to recognize it as being functional on the basis of the monitored electrical parameters in accordance with the lower power consumption and thus the smaller current of the LED emitter.
Dieses eigentlich fehlerhafte Verhalten kann jedoch bedarfsweise durch den Einsatz von entsprechenden selbsttätigen Verfahren der Fehlerverarbeitung zur Bildung von Fahrstrassen-Umgehungen bei der fehlerhaften Signalstelle nun neu berücksichtigt werden, indem diese Verarbeitung deaktiviert wird. Das Deaktivieren ist zulässig, da die Zuverlässigkeit der LED Lichtquellen im Besonderen im Einsatz als kalte Redundanz sehr hoch ist.However, this actually faulty behavior can now, if necessary, be taken into account anew by the use of corresponding automatic methods of error processing for the formation of route bypasses at the faulty signal point by deactivating this processing. Deactivation is allowed because the reliability of the LED light sources is very high, especially when used as cold redundancy.
Durch eine sehr einfache Ausprägung der Schaltung und eine LED-Anordnung als Lichtquelle mit hoher Zuverlässigkeit und einer zeitlich gesehen geringen Einsatzdauer ist eine Überwachung der Funktion der LED-Anordnung nicht zwingend erforderlich, weil die bestimmungsgemässe Funktionalität mit sehr hoher Wahrscheinlichkeit angenommen werden kann.By a very simple form of the circuit and an LED arrangement as light source with high reliability and a temporally low duration of use is a monitoring of the function of the LED array is not mandatory, because the intended functionality can be assumed with very high probability.
Wenn der obige Ansatz zur Zuverlässigkeit bei sehr hohen Sicherheitsanforderungen nicht hinreichend ist, werden noch spezifische Zusatzkriterien in der Überwachung geschaltet, welche je nach Ausprägung selektive Entscheide beim Auftreten von Fehlerrückmeldungen durch die Überwachungseinrichtung zulassen.
20 Watt nominal; Betrieb bei Tag mit ca. 17,5 Watt
Leistung 1 bis 3 Watt im Betrieb
siehe oben
Leistung < 2 Watt im Betrieb
Voraussetzung für den Betrieb:
Die Leistungsaufnahme der redundanten Lichtquelle ist vielfach kleiner im Vergleich zur Glühlampe. Z.B. < 2W. Ist diese Vorgabe nicht erfüllt, sind Anpassungen im Überwachungskreis des Signalstromkreises erforderlich und die Selektivität der Fehlererkennung nimmt dadurch ab.
20 Watt nom. Betrieb bei Tag mit ca. 17,5 Watt
Leistung 1 bis 3 Watt im Betrieb
20 watts nominal; Operation by day with approx. 17.5 Watts
Power 1 to 3 watts in operation
see above
Power <2 watts in operation
Condition for operation:
The power consumption of the redundant light source is often smaller compared to the incandescent lamp. Eg <2W. If this specification is not met, adjustments in the monitoring circuit of the signal circuit are required and the selectivity of the error detection decreases as a result.

Die
Da bei einem Bahnsignal keine Reflektoren (Spiegel) zulässig sind (Verhinderung von Phantomlicht), ist der Lichtstrom über eine Austrittslinse am Signal nur durch die von der Austrittslinse erfasste Raumwinkel gegeben. Mit anderen Worten heisst dies, dass ein grosser Teil des Raumwinkels schwarz ist und damit die Lichtstrahlung absorbiert. Moderne LED-Einheiten mit quasi punktförmigen Lichtquellen erzielen daher Lichtströme bis 100 Lumen und mehr, die ohne weiteres bei wesentlich geringerer Leistungsaufnahme die Leuchtkraft der im Signal eingesetzten Glühlampe erreichen.Since no reflectors (mirrors) are permissible for a path signal (prevention of phantom light), the luminous flux via an exit lens on the signal is given only by the solid angle detected by the exit lens. In other words, this means that a large part of the solid angle is black and thus absorbs the light radiation. Modern LED units with quasi punctiform light sources therefore achieve luminous fluxes of up to 100 lumens and more, which easily reach the luminosity of the incandescent lamp used in the signal at significantly lower power consumption.
Die aktuell neueste Generation von LED hat mittlerweile eine Lichtausbeute bis zu 100 Lumen/Watt. Die Glühlampensignale strahlen in den in der Eisenbahnsicherungstechnik erforderlichen und gebräuchlichen Ausführung (Vermeidung von Phantomlicht) nur einen verhältnismässig geringen Lichtstrom aus. Dieser berechnet sich aus dem aktiven Raumwinkel (Sterradiant) und der Transmission des Farbfilters mit einer Lichtquelle mit weiss A 2856°K . Für die Signalfarbe Rot werden dann noch um die 10 Lumen nach vorne abgestrahlt. Unter diesen Gesichtspunkten ist dann der oben definierte Lichtstrom zu beurteilen.The current latest generation of LEDs now has a luminous efficacy of up to 100 lumens / watt. The incandescent lamp signals radiate in the required and common in the railway safety technology execution (avoidance of phantom light) only a relatively low luminous flux. This is calculated from the active solid angle (sterradiant) and the transmission of the color filter with a light source with white A 2856 ° K. For the signal color red, the 10 lumens are then emitted to the front. From these points of view, the luminous flux defined above must then be assessed.
Der Pfiff der erfindungsgemässen Lösung wird daher darin gesehen, in Signale mit Glühlampen-Lichtquelle eine redundante Ersatzlichtquelle in LED-Technik einzubauen. Dabei wird die Glühlampe unverändert im defekten Zustand im Signalgehäuse belassen und wird in geeigneter Weise als optischer Funktionsteil im Strahlengang der dann leuchtenden LED-Lichtquelle genutzt.The whistle of the inventive solution is therefore seen to incorporate in signals with incandescent light source a redundant replacement light source in LED technology. The incandescent lamp is left unchanged in the defective state in the signal housing and is used in a suitable manner as an optical function part in the beam path of the then shining LED light source.
Die LED Lichtquelle strahlt direkt in die Hauptachse des Strahlenganges aus den Glaskolben der Glühlampe nach vorne gegen die Lichtaustrittsöffnung des Signals gerichtet oder benutzt einen Kollimator für eine Aufbereitung der Abstrahlcharakteristik und / oder einen Lichtleiter für die Zuführung des Lichtes an den an den geeigneten Punkt in der Hauptachse. Dabei wird der Glaskolben der Glühlampe als eine Art Linse genutzt, welche das Licht in geeigneter Weise nach vorne auf die Frontlinse wirft. Es wird dadurch zumindest annähernd die gleiche Wirkung erzielt, wie sie durch den Wendel im Brennpunkt der Optik vorliegt.The LED light source radiates directly into the main axis of the beam path from the glass bulb of the incandescent lamp directed forwardly against the light exit opening of the signal or uses a collimator for processing the radiation characteristics and / or a light guide for the supply of light to the appropriate point in the major axis. In this case, the glass bulb of the incandescent lamp is used as a kind of lens, which throws the light in a suitable manner forward on the front lens. It is thereby achieved at least approximately the same effect as is present through the helix in the focal point of the optics.
Damit wird durch die erfindungsgemässe Lösung eine erhebliche Entlastung in mehreren Punkten erzielt. Zum einen müssen in der stellwerkseitigen Überwachung des Lampenstroms keinerlei Veränderungen vorgenommen werden und die herkömmlichen Glühlampen können gegen solche mit redundater LED-Einheit ausgetauscht werden. Das hierfür erforderliche Design betrifft daher ausschliesslich das Glühlampen-Einsatzmodul und bedarf - wenn überhaupt - höchstens nur geringer Anpassungen am Signal. Zum anderen muss das Wartungspersonal bei dem Ausfall der Glühlampe nicht unmittelbar ausrücken, um die Streckensicherheit möglichst schnell wieder herzustellen, sondern wegen der hohen Ausfallsicherheit der LED-Technik kann mit extrem hoher Wahrscheinlichkeit davon ausgegangen werden, dass die LED-Einheit anstelle der Glühlampe leuchtet. Ein Ausfall der Glühlampe löst daher natürlich einen Service-Auftrag seitens des Stellwerks oder der Leittechnik aus, dieser ist jedoch mit erheblich grösserer Terminfreiheit ausführbar.This is achieved by the inventive solution a significant relief in several points. On the one hand, no changes have to be made in the control of the lamp power on the side of the control panel, and the conventional light bulbs can be replaced by those with a redundant LED unit. The design required for this purpose therefore only concerns the incandescent insert module and requires - if at all - only minimal adjustments to the signal. On the other hand, the maintenance staff does not have to disengage immediately in the event of failure of the light bulb to restore the route safety as quickly as possible, but because of the high reliability of the LED technology can be assumed with an extremely high probability that the LED unit lights up instead of the bulb. Of course, a failure of the light bulb triggers a service order on the part of the interlocking or the control technology, However, this is executable with much greater deadline.
