Als Laterne wird insbesondere eine Leuchte mit Leuchtmittel, Gehäuse und zumindest teilweise lichtdurchlässiger Abdeckung verstanden. Verwendet werden Laternen unter anderem als Schiffsbeleuchtung und/oder Positionslichter. Andere Anwendungsgebiete, auch außerhalb von Schiffen sind möglich. Bevorzugt sind Anwendungsgebiete, auf denen Laternen bzw. Leuchten weitgehend konstante Lichtstärke aufweisen müssen.As a lantern is in particular a lamp with bulbs, housing and at least partially translucent cover understood. Lanterns are used under other than ship lighting and / or position lights. Other applications, also outside of ships are possible. Preferred are application areas in which Lanterns or lights must have largely constant light intensity.
Elektrische Leuchtmittel unterscheiden sich nicht nur hinsichtlich der Leistungsaufnahme. Für spezielle Anwendungen ist eine konstante Lichtstärke über die Lebensdauer des Leuchtmittels von größter Bedeutung, etwa bei Positionslichtern an Bord von Schiffen. Die gesetzlichen Bestimmungen verlangen Mindestreichweiten. Die hierfür ausgelegten Laternen unterliegen der Alterung und äußeren Einflüssen, etwa der Umgebungstemperatur. In Abhängigkeit von zumindest diesen beiden Faktoren können je nach Leuchtmittel Änderungen der Lichtstärke, insbesondere Schwächungen, auftreten. Mit der vorliegenden Erfindung sollen die beschriebenen Probleme verringert oder sogar vermieden werden.Electric bulbs differ not only in terms of power consumption. For special applications is a constant light intensity over the life of the Illuminant of utmost importance, such as position lights on board ships. The statutory requirements require minimum ranges. The lanterns designed for this purpose are subject to aging and external influences, such as the ambient temperature. Depending on at least these two factors may change depending on the light source the light intensity, in particular weakenings, occur. With the present Invention, the problems described should be reduced or even avoided.
Die erfindungsgemäße Laterne ist gekennzeichnet durch mindestens einen Sensor zum Erfassen der Lichtstärke des Leuchtmittels. Natürlich können auch mehrere Leuchtmittel und/oder mehrere Sensoren vorgesehen sein. Der Sensor liefert ein Ausgangssignal, mit dem Maßnahmen zur Steuerung des Betriebs der Laterne ausgelöst werden können. Einfache Sensoren sind beispielsweise Photodioden.The lantern according to the invention is characterized by at least one sensor for Detecting the light intensity of the bulb. Of course, you can also use several bulbs and / or a plurality of sensors may be provided. The sensor provides an output signal, with the measures for controlling the operation of the lantern can be triggered. easy Sensors are, for example, photodiodes.
Vorteilhafterweise ist die Laterne gekennzeichnet durch Mittel zum Ändern des Stroms oder der Spannung für das Leuchtmittel in Abhängigkeit vom Ausgangssignal des Sensors. Derartige Mittel können in einer geeigneten elektronischen Schaltung dargestellt werden.Advantageously, the lantern is characterized by means for changing the current or the voltage for the lamp depending on the output signal of the sensor. Such means may be presented in a suitable electronic circuit become.
Nach einem weiteren Gedanken der Erfindung können Mittel zum Abschalten des Leuchtmittels in Abhängigkeit vom Ausgangssignal des Sensors und/oder der elektrischen Leistungsaufnahme des Leuchtmittels vorgesehen sein. Die Funktion ist durch eine geeignete elektronische Schaltung ausführbar. Auch kann eine Umschaltung auf ein Reservesystem vorgesehen sein, etwa auf eine weitere Laterne (externe Reserve) oder auf weitere Leuchtmittel innerhalb der Laterne (interne Reserve).According to a further aspect of the invention, means for switching off the Illuminant depending on the output signal of the sensor and / or the electrical Power consumption of the light source may be provided.

Also, a switch to a backup system be provided, for example, on another lantern (external reserve) or on additional bulbs within the lantern (internal reserve).
Vorteilhafterweise ist als Leuchtmittel mindestens eine LED (Licht emittierende Diode) vorgesehen. Die derzeit verbreiteten LED verringern die abgegebene Lichtstärke mit zunehmendem Lebensalter und mit steigender Temperatur. Gerade in Anwendungsbereichen, in denen bestimmte Mindestlichtstärken oder überhaupt konstante Lichtstärken gefordert werden, ermöglicht die Erfindung erstmals die Verwendung von LEDs.Advantageously, as the light source at least one LED (light emitting diode) intended. The currently widespread LED reduce the emitted light intensity with increasing Age and with increasing temperature. Especially in application areas, in which certain minimum light levels or constant light levels required For the first time, the invention enables the use of LEDs.
Nach einem weiteren Gedanken der Erfindung sind mehrere LEDs ringförmig oder teilringförmig angeordnet unter Bildung einer im wesentlichen radialen Abstrahlebene. Der Hauptanteil des abgestrahlten Lichts jeder einzelnen LED wird demnach in radialer Richtung abgestrahlt. Durch die Anordnung mehrerer LED entlang eines gedachten Ringes oder Teilringes kann die Funktion eines Rundumlichts oder eines Teils hiervon nachgebildet werden. Bei vertikaler Ringachse ergibt sich so eine horizontale oder kegelförmige Abstrahlebene bzw. eine Abstrahlebene senkrecht oder unter einem Winkel zur Ringachse.According to a further aspect of the invention, a plurality of LEDs are annular or semi-annular arranged to form a substantially radial Abstrahlebene. Of the Main part of the radiated light of each individual LED is therefore in the radial direction radiated. By arranging several LEDs along an imaginary ring or partial ring can simulate the function of a omnidirectional light or a part thereof become. With a vertical ring axis, this results in a horizontal or conical Abstrahlebene or a Abstrahlebene perpendicular or at an angle to the ring axis.
Vorteilhafterweise erstreckt sich entlang der Ringachse ein zentraler Träger für die LEDs, mit einer umlaufenden Wandung, auf der die LEDs mittelbar oder unmittelbar angeordnet sind. Der zentrale Träger kann länglich ausgebildet sein unter Definition einer Längsachse, etwa als massiver oder hohler Stab. Die von den LEDs erzeugte Wärme wird vom zentralen Träger, der hier als Kühlkörper fungiert, in Richtung der Ringachse bzw. Längsachse abgeführt. Die thermische Belastung der LEDs ist dadurch geringer. Dies wirkt sich günstig auf die Gesamtlebensdauer der LEDs aus, da die höhere Leistungsaufnahme der LEDs durch entsprechende Regelung in geringerem Maße erforderlich ist als in einer Ausführung ohne Kühlkörper.Advantageously, a central support for the LEDs extends along the axis of the ring, with a circumferential wall on which the LEDs are arranged directly or indirectly are. The central support may be elongate defining a longitudinal axis, as a solid or hollow rod. The heat generated by the LEDs is dissipated by the central carrier, which acts here as a heat sink, in the direction of the ring axis or longitudinal axis dissipated. The thermal load of the LEDs is thereby lower. This affects itself favorable to the overall life of the LEDs, since the higher power consumption of the LEDs is required by appropriate regulation to a lesser extent than in an embodiment without heat sink.
Nach einem weiteren Gedanken der Erfindung ist mindestens ein Sensor senkrecht zur Hauptabstrahlrichtung der nächstliegenden LEDs angeordnet. Auf diese Weise wird insbesondere das Streulicht erfasst. Bei ringförmiger Anordnung der LED mit radialer Abstrahlebene liegt der Sensor außerhalb der Abstrahlebene mit einer Haupterfassungsrichtung des Sensors quer zur Abstrahlebene gerichtet oder mit Ausrichtung auf die nächstliegende LED. Natürlich können auch mehrere Sensoren vorgesehen sein.According to a further aspect of the invention, at least one sensor is perpendicular to Main emission direction of the nearest LEDs arranged. This way, in particular the scattered light detected. With annular arrangement of the LED with radial radiation level the sensor is located outside the radiation level with a main detection direction of the sensor directed transversely to the plane of abstraction or with orientation to the nearest LED. Of course, several sensors can be provided.
Nach einem weiteren Gedanken der Erfindung sind mindestens doppelt so viele LEDs wie Sensoren vorgesehen, insbesondere mindestens vier Mal so viele LEDs. Entsprechend empfängt ein Sensor das Streulicht von mehreren LEDs. Die Anzahl der Sensoren bleibt klein, während die Funktion der Laterne gewährleistet bleibt.According to another aspect of the invention, at least twice as many LEDs as are Sensors provided, in particular at least four times as many LEDs. Corresponding a sensor receives the scattered light from several LEDs. The number of sensors remains small, while the function of the lantern remains guaranteed.

Außerdem ist mindestens ein Sensor zur Erfassung der Lichtstärke der Leuchtmittel am Einsatz vorgesehen. Als Leuchtmittel werden vorzugsweise LEDs verwendet. Die Sensoren erfassen deren Streulicht und sind vorzugsweise auf einer um den Kühlkörper umlaufenden Platine und mit axialem Abstand zu den Leuchtmitteln angeordnet. Dabei erstreckt sich die Platine senkrecht zur Längsachse oder parallel zur Hauptabstrahlrichtung der LEDs.An independent idea of the invention relates to an insert for the lantern or Lamp. The insert has an elongated heat sink with a longitudinal axis and in at least one plane perpendicular to the longitudinal axis arranged bulbs. Furthermore At least one sensor for detecting the light intensity of the light source is provided on the insert. As the light source preferably LEDs are used. The sensors detect their scattered light and are preferably on a circulating around the heat sink board and arranged at an axial distance from the bulbs. The board extends perpendicular to the longitudinal axis or parallel to the main emission direction of the LEDs.
Schließlich betrifft die Erfindung auch ein Verfahren zum Betreiben einer Laterne mit mindestens einem elektrischen Leuchtmittel. Das Verfahren ist dadurch gekennzeichnet, dass die Lichtstärke des abgestrahlten Lichts ständig oder regelmäßig erfasst und in Abhängigkeit von der erfassten Lichtstärke eine Anpassung von Strom oder Spannung für das Leuchtmittel durchgeführt wird, um so die Lichtstärke auf einem definierten Sollwert oder Mindestwert zu halten. Durch geeignete Sensoren kann das Streulicht der Leuchtmittel erfasst werden. Letztere sind insbesondere als LEDs ausgeführt.Finally, the invention also relates to a method for operating a lantern with at least an electric bulb. The method is characterized in that the luminous intensity of the emitted light is recorded constantly or regularly and in dependence from the detected intensity of an adjustment of current or voltage for the Light source is performed so as to adjust the light intensity to a defined setpoint or Minimum value. By suitable sensors, the scattered light of the bulbs be recorded. The latter are designed in particular as LEDs.
Vorteilhafterweise wird das mindestens eine Leuchtmittel bei Überschreiten einer definierten elektrischen Leistung abgeschaltet, vorzugsweise alle Leuchtmittel. Bei Abschaltung der Leuchtmittel einer Laterne kann auch vorgesehen sein, dass zugleich ein Reservesystem aufgeschaltet wird, etwa eine benachbarte zweite Laterne. Advantageously, the at least one light source is exceeded when a defined switched off electrical power, preferably all bulbs.

In Weiterbildung des erfindungsgemäßen Verfahrens ist vorgesehen, dass die Leuchtmittel regelmäßig kurzzeitig ausgeschaltet werden, dass bei ausgeschalteten Leuchtmitteln Fremdlicht erfasst und zur Bestimmung der tatsächlichen Lichtstärke der Leuchtmittel berücksichtigt wird. Die von den Sensoren detektierte Lichtstärke setzt sich zusammen aus dem Licht der Leuchtmittel und gegebenenfalls vorhandenem und zumeist wechselndem Fremdlicht. Letzteres wird durch das genannte kurzzeitige Ausschalten der Leuchtmittel erfasst. Beispielsweise werden die Leuchtmittel jede Minute für ca. 10 Millisekunden ausgeschaltet. Besonders kurze Ausschaltphasen können mit LEDs gut verwirklicht werden.In a further development of the method according to the invention, it is provided that the lighting means be switched off regularly for a short time, that with switched off bulbs External light detected and to determine the actual light intensity of the bulbs is taken into account. The detected by the sensors light intensity is composed from the light of the bulbs and possibly existing and mostly changing Extraneous light. The latter is due to the said short-term switching off the light source detected. For example, the bulbs every minute for about 10 milliseconds switched off.

Teil des Einsatzes 30 ist im vorliegenden Beispiel außerdem eine mittlere große Platine 35, die sich parallel zur Hauptabstrahlebene 25 scheibenringförmig um den Kühlkörper 31 herum erstreckt. Ein Innendurchmesser der mittleren Platine liegt noch auf den Platinen 33 auf, nahe unterer Enden derselben. Von jeder kleinen Platine 33 besteht eine elektrisch leitende Verbindung zur mittleren Platine 35, etwa als Lötfahne oder dergleichen.Part of the insert 30 is in the present example also a medium sized board 35, which is parallel to the Hauptabstrahlebene 25 disc-shaped ring around the heat sink 31st extends around. An inner diameter of the middle board is still on the boards 33 on, near lower ends of the same. From each small board 33 is an electrical conductive connection to the middle board 35, such as a solder tag or the like.
Über Abstandhalter 36 ist eine untere große Platine 37 mit der mittleren Platine 35 verbunden. Dabei erstrecken sich die Abstandhalter 36 parallel zur Längsachse 11, die zugleich Längsachse des Kühlkörpers 31 ist. Die untere Platine 37 ist scheibenringförmig ausgebildet mit einem Innendurchmesser zur Aufnahme eines unteren Endes des Kühlkörpers 31 und mit einem Außendurchmesser ähnlich oder gleich der mittleren Platine 35. Insgesamt sind drei Abstandhalter 36 mit gleichmäßigen Abständen zueinander zur Verbindung der beiden größeren Platinen 35, 37 vorgesehen. Beide größeren Platinen 35, 37 können elektronische Bauelemente zur Ansteuerung der LEDs 32 aufweisen. Die untere Platine 37 trägt außerdem eine Klemmleiste 38 an ihrer Unterseite für nicht gezeigte elektrische Leitungen.About spacers 36, a lower large board 37 is connected to the middle board 35. In this case, the spacers 36 extend parallel to the longitudinal axis 11, the is also the longitudinal axis of the heat sink 31. The lower board 37 is disc-shaped formed with an inner diameter for receiving a lower end of the heat sink 31 and with an outer diameter similar to or equal to the middle board 35th Overall, three spacers 36 with equal distances from each other for connection the two larger boards 35, 37 are provided. Both larger boards 35, 37 may have electronic components for driving the LEDs 32. The lower one Board 37 also carries a terminal block 38 on its underside for not shown electric lines.
Die Platinen 33, 35, 37 sind zum einen über radial gerichtete Schraubverbindungen im Bereich der kleinen Platinen 33 mit dem Kühlkörper 31 verbunden und zum anderen über den Abstandhaltern 36 zugeordnete Winkelstücke 39, welche zwischen den beiden größeren Platinen 35, 37 mit dem Kühlkörper verbunden, insbesondere verschraubt sind.The boards 33, 35, 37 are on the one hand via radially directed screw connections in Area of the small boards 33 connected to the heat sink 31 and the other over the spacers 36 associated angle pieces 39, which between the two larger Blanks 35, 37 connected to the heat sink, in particular screwed.
Die mittlere große Platine 35 trägt zwei Sensoren 40, mit denen das von den LEDs 32 ausgehende Streulicht gemessen werden kann. Ausgangssignale der Sensoren 40 werden in nicht gezeigten elektronischen Schaltungen verarbeitet und zur Steuerung des Betriebs der Laterne ausgewertet. The central large board 35 carries two sensors 40, with which of the LEDs 32nd outgoing stray light can be measured. Output signals of the sensors 40 are processed in electronic circuits, not shown, and for controlling the operation evaluated the lantern.
Die Lichtstärke der LEDs verringert sich mit zunehmendem Alter und zunehmender Temperatur. Um eine gewisse Mindestlichtstärke zu halten, erfolgt eine Regelung der Aufnahmeleistung der LEDs in Abhängigkeit vom Ausgangssignal der Sensoren 40. Nach Erreichen einer Obergrenze der Leistungsaufnahme wird die Laterne abgeschaltet. Die Erhöhung der Aufnahmeleistung kann im Einzelfall auch den Ausfall einer einzelnen LED ausgleichen.The intensity of the LEDs decreases with age and increasing temperature. In order to keep a certain minimum light intensity, there is a regulation of the recording power of the LEDs in response to the output of the sensors 40. Nach Reaching an upper limit of power consumption, the lantern is turned off. The Increasing the recording power can in individual cases, the failure of a single LED compensate.
Möglich ist auch das Umschalten auf ein Reservesystem in Abhängigkeit von der Lichtstärke und/oder Leistungsaufnahme. Das Reservesystem kann durch zusätzliche LEDs innerhalb der Laterne (nicht gezeigt) gebildet sein oder als externe Reserve durch eine zusätzliche Laterne 41, siehe Fig. 9 und 10. Derart übereinander angeordnete (und miteinander verbundene) Laternen sind im deutschen Gebrauchsmuster 201 14 306.2 gezeigt, dort mit Blitzleuchtmitteln.It is also possible to switch to a reserve system depending on the light intensity and / or power consumption. The backup system can be powered by additional LEDs be formed within the lantern (not shown) or as an external reserve by a additional lantern 41, see Figs. 9 and 10. Such superimposed (and each other connected) lanterns are shown in German Utility Model 201 14 306.2, there with flash bulbs.
Die Sensoren 40 weisen jeweils eine Hauptabtastrichtung auf, welche sich parallel zur Längsachse 11 erstreckt und die Hauptabstrahlebene 25 mit Abstand zu den LEDs 32 kreuzt.The sensors 40 each have a main scanning direction which is parallel to the Longitudinal axis 11 extends and the Hauptabstrahlebene 25 at a distance from the LEDs 32nd crosses.
Die von den Sensoren 40 erfasste Lichtstärke ist auch von eintreffendem Fremdlicht abhängig. Um dessen Einfluss zu eliminieren, wird das Fremdlicht kurzzeitig erfasst und aus dem Streulicht herausgerechnet. Möglich ist dies insbesondere durch eine nicht sichtbare kurzzeitige Abschaltung der LEDs, beispielsweise für etwa 10 Millisekunden. Dieser kurze Zeitabschnitt ist für das Auge nicht sichtbar. Während dieser Zeit wird das Fremdlicht erfasst und so eine Nulllinie für das Streulicht der LEDs festgelegt. Die Streulichtmessung kann kontinuierlich oder in Abständen erfolgen, beispielsweise jeweils kurz nach dem kurzzeitigen Ausschalten der LEDs. Das Ausschalten für die Erfassung des Fremdlichts erfolgt beispielsweise regelmäßig jede Minute einmal.The light intensity detected by the sensors 40 is also dependent on incoming extraneous light. In order to eliminate its influence, the extraneous light is briefly detected and off the scattered light out. This is possible in particular by an invisible short-term shutdown of the LEDs, for example, for about 10 milliseconds. This short one Period of time is not visible to the eye. During this time, the extraneous light is detected and set a zero line for the stray light of the LEDs. The scattered light measurement can be continuous or at intervals, for example just after each momentarily switching off the LEDs. Switching off for detection of extraneous light For example, every minute takes place regularly.
Der Kühlkörper 31 ist aus gut wärmeleitendem Metall hergestellt, insbesondere als massiver oder hohler Stab mit an beiden Enden vorgesehenen quergerichteten Endflächen 42, 43. Die Endflächen 42, 43 liegen am Deckel 12 bzw. Boden 14 an und ermöglichen so eine Übertragung der Wärme auf Deckel und Boden. The heat sink 31 is made of good heat conducting metal, in particular as solid or hollow rod having transverse end surfaces 42 provided at both ends, 43. The end surfaces 42, 43 are on the lid 12 and bottom 14 and allow so a transfer of heat to the lid and bottom.
