Definitions
- the invention relates to a device for receiving and electrically contacting a luminous means in a headlamp according to the preamble of claim 1.
- a headlamp for film, studio, stage lighting and other applications which has a headlamp housing, which serves to receive a luminous body, a transparent cover in the form of a protective screen or a lens disc and a reflector.
- lamps or luminous bodies are burners or lamps, preferably single-ended discharge lamps, in a vertical or horizontal mounting position, that is, in each case perpendicular to the optical axis, or in the axial installation position, that is, in the optical axis used.
- the lamps have a gas-filled glass body with electrodes arranged therein, a lamp cap through which the supply lines are led to the electrodes, and two or more contact pins which are arranged on the end of the lamp cap opposite the glass body.
- the contact pins are inserted for connection to a voltage source in the sockets of a lamp socket connected to the lamp housing, with a close fit between the sockets and the contact pins for the high current levels of the lamp current to be transmitted is necessary.
- the contact pins serve, for example, discharge lamps which are socketed on one side as fastening means for the discharge lamp.
- the receiving device of clamping jaws which engage around the lamp base and by means of the adjusting device in an open position in which the lamp cap is released, and in a locking position in which the lamp cap is fixed, are adjustable.
- the adjusting device consists of a pawl with two geometrically identically shaped inclined surfaces which rest on the upper and lower clamping jaw in such a way that when an adjustment of the pawl, the clamping jaws are radially spread.
- a light bulb can be used.
- the bulbs are inserted through the reflector from the front of the headlamp when the front cover is open and clamped in the bulb socket behind it. Only when the bulb centric and straight at the end stop of the bulb holder rests on the clamping device may be operated, otherwise damage to the bulb socket, the sockets or the bulb socket and the contact pins caused by breakage, flashovers or corrosion.
- the bulbs must be observed from the front when inserting into the bulb holder to the light, d. H. in mutually aligned contact pins of the bulb and the sockets of the bulb socket to use, while on the other hand, the operator must hold the bulb with one hand and center and operate with the other hand, the clamping device whose controls are usually located on the side of the headlight housing.
- the operator can no longer be sufficiently far in front of the headlight with larger headlight housings with a correspondingly large headlight housing in order to simultaneously observe the straight onset of the light source and to be able to operate the clamping device.
- Another problem is that on the one hand a for the reflection of the light emitted by the light optically cheaper and therefore the smallest possible reflector opening is desired, but on the other hand, the visual inspection upon insertion of the light in the light bulb holder difficult because it obstructs the view on the bulb holder, in particular, when the light source is already partially inserted into the light-emitting means, so that the operator can no longer recognize whether the light source is correctly inserted or tilted and consequently contact the pins of the light source the sockets of the light emitting only insufficient.
- a shift of the clamping device for non-positive and / or positive clamping of the bulb socket to the front of the headlight housing would not lead to any significant improvement in visual inspection when inserting the bulb in the bulb holder, since the visual inspection would be hindered anyway by a narrow reflector opening, so that only one enlarged reflector opening would be an improved visual inspection under taking into account a deteriorated beam reflection and poorer optical properties of the headlight would be possible.
- JP 09-185978 A known to provide a recess in the lamp base, at the bottom of a torsion spring is arranged, whose ends are bent upwards and engagement projections which engage in corresponding engagement recesses in the inner wall of the lamp socket. If the lamp base is inserted into the lamp socket, this leads to the rotation of the torsion spring and upon engagement of the engagement projections in the engagement recesses, an acoustic signal is generated.
- a device for detecting an insufficient connection of a lamp cap of a discharge lamp with a lamp holder, which consists of a connecting cable and a mounting bracket, which can be connected to the lamp socket only when the lamp cap is fully connected to the lamp socket.
- a lighting device with a single-capped spotlight is known in which a connection of the radiator is excluded with a socket when the spotlight is unsuitable.
- the socket for receiving the radiator is connected to a sensor element which receives magnetic or optical pulses, while the socket facing part of the base is provided with a marking element which emits magnetic or optical pulses which are received by the sensor element after the marker has been stimulated to deliver the pulses by an excitation means.
- a discharge lamp is known, the base of which is connected to a socket containing a device for generating a high voltage from an AC voltage.
- the socket has a recess at the end of which a high voltage contact is arranged, which is connected to a protruding from the base of the discharge lamp pin.
- contacts for preheating the cathode as well as with a circumferential lead collar of the lamp cap corresponding contacts are provided with which a signal applied to the contacts of the socket signal is shorted. With the short circuit of the contacts, the correct seating of the lamp cap is signaled in the high voltage releasing socket.
- an electrical control display which indicates the mutual locking of a lamp cap with a bayonet connector.
- the lamp cap has a pair of radially directed and diametrically opposed pins which engage in grooves of L-shaped profile of the sheath of the connector.
- the bayonet connection is made by inserting the pins in the grooves by axial displacement and subsequent rotation of the lamp cap.
- a movable tongue is pressed against a fixed tongue of a pair of taps on the electrical indicator, closing a circuit and actuating a control circuit for powering the lamp.
- the pins of the lamp cap are not penetrated far enough to the bottom of the L-shaped grooves, so that the movable tongue does not come to rest on the fixed tongue.
- the tongues form a contact pair of a switch whose open or closed state controls the control circuit for the power supply of the lamp, so that an unwanted power supply is prevented when removed or improperly inserted lamp.

Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Aufnahme und elektrischen Kontaktierung eines Leuchtmittels in einem Scheinwerfer gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for receiving and electrically contacting a luminous means in a headlamp according to the preamble of
Aus der
Die Lampen weisen einen gasgefüllten Glaskörper mit darin angeordneten Elektroden, einen Lampensockel, durch den die Zuleitungen zu den Elektroden geführt sind, und zwei oder mehr Kontaktstifte auf, die an dem dem Glaskörper entgegengesetzten Ende des Lampensockels angeordnet sind. Die Kontaktstifte werden zur Verbindung mit einer Spannungsquelle in die Steckbuchsen einer mit dem Lampengehäuse verbundenen Lampenfassung eingefügt, wobei eine enge Passung zwischen den Steckbuchsen und den Kontaktstiften für die zu übertragenden hohen Stromstärken des Lampenstromes notwendig ist.The lamps have a gas-filled glass body with electrodes arranged therein, a lamp cap through which the supply lines are led to the electrodes, and two or more contact pins which are arranged on the end of the lamp cap opposite the glass body. The contact pins are inserted for connection to a voltage source in the sockets of a lamp socket connected to the lamp housing, with a close fit between the sockets and the contact pins for the high current levels of the lamp current to be transmitted is necessary.
Gleichzeitig dienen die Kontaktstifte beispielsweise von einseitig gesockelten Entladungslampen als Befestigungsmittel für die Entladungslampe. Da mit wachsenden Lampenleistungen auch die Baugröße der Entladungslampen und insbesondere die Baulänge des Glaskörpers und des Lampensockels zunimmt, weisen die Lampen bei größeren Lampenleistungen eine solche Baugröße auf, dass insbesondere bei einer horizontalen Einbaulage der Entladungslampen erhebliche Kräfte auf die zusätzlich zur Stromzufuhr auch als Befestigungskontakte wirkenden Kontaktstifte ausgeübt werden. Diese Kräfte führen zu einer Verschlechterung des Kontaktes zwischen den Kontaktstiften und den Steckbuchsen der Lampenfassung, was mit einem erhöhten Übergangswiderstand bei der Übertragung des Lampenstromes, einer Verlagerung der Lampe aus dem Brennpunkt des Reflektors und dadurch bedingt einer verringerten Lichtausbeute sowie mit einer Übertragung der Kräfte in das Lampeninnere verbunden ist, was zu unzulässigen Spannungen und schließlich zum Ausfall der Lampe führen kann. Die Nachteile der ausschließlichen Lagerung der Lampe über die Kontaktstifte wirken sich jedoch nicht nur im statischen Bereich über die Baugröße der Lampe aus, sondern insbesondere auch im dynamischen Bereich beim Transport eines Scheinwerfers bzw. dessen Betrieb mit ruckartigen Schwenkbewegungen, Stößen auf das Lampengehäuse und dergleichen.At the same time, the contact pins serve, for example, discharge lamps which are socketed on one side as fastening means for the discharge lamp. As with increasing lamp power and the size of the discharge lamps and in particular the length of the glass body and the lamp base increases, the lamps at larger lamp power on such a size that especially in a horizontal mounting position of the discharge lamps considerable forces acting on the addition to the power supply as mounting contacts Contact pins are exercised. These forces lead to a deterioration of the contact between the pins and the sockets of the lamp socket, resulting in an increased contact resistance in the transmission of the lamp current, a displacement of the lamp from the focus of the reflector and thereby a reduced light output and with a transfer of forces in the lamp interior is connected, which can lead to inadmissible voltages and eventually to failure of the lamp. However, the disadvantages of the exclusive storage of the lamp via the contact pins affect not only the static range on the size of the lamp, but especially in the dynamic range when transporting a headlamp or its operation with jerky pivoting movements, shocks on the lamp housing and the like.
Um ein Lampengehäuse für Lampen mit unterschiedlichen Lampensockeldurchmessem ohne Austausch einer Aufnahmeeinrichtung einsetzen und die Kontaktstifte der Lampen ausschließlich zur Übertragung des Lampenstromes nutzen zu können, besteht bei dem aus der
Beim Betätigen der Verstelleinrichtung zum Öffnen und Schließen der Klemmbacken erfolgt gleichzeitig ein Öffnen und Schließen der die Kontaktstifte des Leuchtmittels aufnehmenden Steckbuchsen, so dass durch gleichzeitige Freigabe der Kontaktstifte bei einer Betätigung der Verstelleinrichtung zum Öffnen und Schließen der Klemmbacken das Leuchtmittel durch Freigabe des Leuchtmittelsockels leicht entnommen bzw. in der Öffnungsstellung der Lampenhalterung ein Leuchtmittel eingesetzt werden kann.When you press the adjustment for opening and closing of the jaws takes place at the same time opening and closing the pins of the lamp receiving receptacles, so easily removed by releasing the light socket by simultaneously releasing the pins on actuation of the adjustment for opening and closing the jaws or in the open position of the lamp holder, a light bulb can be used.
Bei Scheinwerfern mit einseitig gesockelten Leuchtmitteln werden die Leuchtmittel bei geöffneter frontseitiger Abdeckung von der Vorderseite des Scheinwerfers durch den Reflektor gesteckt und in der dahinter liegenden Leuchtmittelfassung festgeklemmt. Erst wenn das Leuchtmittel zentrisch und gerade am Endanschlag der Leuchtmittelfassung anliegt darf die Klemmvorrichtung betätigt werden, da ansonsten Schäden an der Leuchtmittelfassung, den Steckbuchsen bzw. dem Leuchtmittelsockel und den Kontaktstiften durch Bruch, Überschläge oder Korrosion entstehen.In the case of headlamps with single-cap lamps, the bulbs are inserted through the reflector from the front of the headlamp when the front cover is open and clamped in the bulb socket behind it. Only when the bulb centric and straight at the end stop of the bulb holder rests on the clamping device may be operated, otherwise damage to the bulb socket, the sockets or the bulb socket and the contact pins caused by breakage, flashovers or corrosion.
Mit zunehmender Leistung und damit Baugröße der Leuchtmittel treten aber Probleme beim korrekten Einsetzen der Leuchtmittel in die Leuchtmittelfassung des Scheinwerfers auf. Einerseits muss das Leuchtmittel beim Einsetzen in die Leuchtmittelfassung von vorne beobachtet werden, um das Leuchtmittel gerade, d. h. bei miteinander fluchtenden Kontaktstiften des Leuchtmittels und der Steckbuchsen der Leuchtmittelfassung, einsetzen zu können, während andererseits der Bediener das Leuchtmittel mit einer Hand festhalten und zentrieren und mit der anderen Hand die Klemmvorrichtung bedienen muss, deren Bedienungselemente sich üblicherweise an der Seite des Scheinwerfergehäuses befinden. Dabei kann der Bediener aber bei größeren Scheinwerferleistungen mit entsprechend großem Scheinwerfergehäuse nicht mehr genügend weit vor dem Scheinwerfer stehen, um gleichzeitig das gerade Einsetzen des Leuchtmittels beobachten und die Klemmvorrichtung bedienen zu können.With increasing performance and thus size of the bulbs but problems occur in the correct insertion of the bulbs in the bulb holder of the headlight. On the one hand, the bulbs must be observed from the front when inserting into the bulb holder to the light, d. H. in mutually aligned contact pins of the bulb and the sockets of the bulb socket to use, while on the other hand, the operator must hold the bulb with one hand and center and operate with the other hand, the clamping device whose controls are usually located on the side of the headlight housing. However, the operator can no longer be sufficiently far in front of the headlight with larger headlight housings with a correspondingly large headlight housing in order to simultaneously observe the straight onset of the light source and to be able to operate the clamping device.
Ein weiteres Problem besteht darin, dass einerseits eine für die Reflektion des vom Leuchtmittel abgegebenen Lichts optisch günstigere und deshalb möglichst kleine Reflektoröffnung erwünscht ist, die aber andererseits die Sichtkontrolle beim Einsetzen des Leuchtmittels in die Leuchtmittelfassung erschwert, da sie die Sicht auf die Leuchtmittelfassung behindert, insbesondere wenn das Leuchtmittel bereits teilweise in die Leuchtmittelfassung eingesetzt ist, so dass der Bediener nicht mehr erkennen kann, ob das Leuchtmittel korrekt eingeführt oder verkantet ist und demzufolge die Kontaktstifte des Leuchtmittels die Steckbuchsen der Leuchtmittelfassung nur unzureichend kontaktieren.Another problem is that on the one hand a for the reflection of the light emitted by the light optically cheaper and therefore the smallest possible reflector opening is desired, but on the other hand, the visual inspection upon insertion of the light in the light bulb holder difficult because it obstructs the view on the bulb holder, in particular, when the light source is already partially inserted into the light-emitting means, so that the operator can no longer recognize whether the light source is correctly inserted or tilted and consequently contact the pins of the light source the sockets of the light emitting only insufficient.
Eine Verlagerung der Klemmvorrichtung zum kraft- und/oder formschlüssigen Einklemmen des Leuchtmittelsockels zur Vorderseite des Scheinwerfergehäuses würde zu keiner wesentlichen Verbesserung der Sichtkontrolle beim Einsetzen des Leuchtmittels in die Leuchtmittelfassung führen, da die Sichtkontrolle durch eine enge Reflektoröffnung ohnehin behindert wäre, so dass nur bei einer vergrößerten Reflektoröffnung eine verbesserte Sichtkontrolle unter in Kaufnahme einer verschlechterten Strahlenreflexion und schlechteren optischen Eigenschaften des Scheinwerfers möglich wäre.A shift of the clamping device for non-positive and / or positive clamping of the bulb socket to the front of the headlight housing would not lead to any significant improvement in visual inspection when inserting the bulb in the bulb holder, since the visual inspection would be hindered anyway by a narrow reflector opening, so that only one enlarged reflector opening would be an improved visual inspection under taking into account a deteriorated beam reflection and poorer optical properties of the headlight would be possible.

Diese bekannten Vorrichtungen zur Erfassung des korrekten Sitzes eines Lampensockels in einer Lampenfassung bzw. zum Blockieren des Einsetzens eines ungeeigneten Leuchtmittels in eine Lampenfassung sind sehr aufwändig gestaltet und erfordern entsprechende Einrichtungen sowohl am Lampensockel als auch an der Lampenfassung, so dass sie nur dann funktionsfähig sind, wenn der Lampensockel des Leuchtmittels mit den entsprechenden Erfassungsmitteln versehen ist. Die aufwändige Gestaltung der Erfassungseinrichtungen führt zudem zu einer erhöhten Störempfindlichkeit, die zu fehlerhaften Erfassungen führt, insbesondere unter Berücksichtigung der hohen Temperaturen im Bereich des Lampensockels und der Lampenfassung.These known devices for detecting the correct fit of a lamp socket in a lamp socket or to block the insertion of an inappropriate lamp in a lamp socket are very complex and require appropriate facilities on both the lamp base and the lamp socket, so that they are only functional, if the lamp base of the lamp is provided with the corresponding detection means. The elaborate design of the detection devices also leads to increased susceptibility to interference, which leads to erroneous detection, especially taking into account the high temperatures in the area of the lamp cap and the lamp socket.
Aus der
Bei unzureichender Verriegelung der Lampe sind die Zapfen des Lampensockels nicht weit genug zum Boden der L-förmigen Auskehlungen vorgedrungen, so dass die bewegliche Zungenicht zur Anlage an der festen Zunge kommt. Damit bilden die Zungen ein Kontaktpaar eines Schalters, dessen geöffneter oder geschlossener Zustand die Steuerschaltung für die Stromversorgung der Lampe ansteuert, so dass eine ungewollte Stromversorgung bei herausgenommener oder unsachgemäß eingesetzter Lampe verhindert wird.With insufficient locking of the lamp, the pins of the lamp cap are not penetrated far enough to the bottom of the L-shaped grooves, so that the movable tongue does not come to rest on the fixed tongue. Thus, the tongues form a contact pair of a switch whose open or closed state controls the control circuit for the power supply of the lamp, so that an unwanted power supply is prevented when removed or improperly inserted lamp.
Bei dieser elektrischen Kontrollanzeige ist ebenfalls keine Kontrolle der Bewegung beim Einsetzen des Lampensockels in den Verbinder möglich, sondern lediglich eine Kontrolle des Erreichens der verriegelten Endposition der Bajonettverbindung zwischen dem Lampensockel und dem Verbinder.Also in this electrical control display, there is no control over the movement upon insertion of the lamp cap into the connector, but only a check of the achievement of the locked end position of the bayonet connection between the lamp cap and the connector.
Aufgabe der vorliegenden Erfindung ist es, eine Überwachungseinrichtung für eine Vorrichtung zur Verbindung und elektrischen Kontaktierung eines Leuchtmittelsockels eines Leuchtmittels und einer Leuchtmittelfassung eines Scheinwerfers zu schaffen, die bei einfachem Aufbau, einfacher und sicherer Handhabung und Unempfindlichkeit gegenüber äußeren Einflüssen und Störungen ein korrektes Einsetzen des Leuchtmittelsockels in die Leuchtmittelfassung auch bei großen Scheinwerferleistungen und unter schlechten Sichtbedingungen gewährleistet.Object of the present invention is to provide a monitoring device for a device for connection and electrical contacting of a lamp socket of a lamp and a bulb holder of a headlamp, the simple installation, easy and safe handling and insensitivity to external influences and disturbances correct insertion of the lamp socket ensured in the bulb holder even with large headlight performance and in poor visibility conditions.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1 und 10 mit optischen und mechanischen Mitteln gelöst.This object is achieved by the features of
Die erfindungsgemäße Lösung gewährleistet bei einfachem Aufbau, einfacher und sicherer Handhabung und Unempfindlichkeit gegenüber äußeren Einflüssen und Störungen ein korrektes Einsetzen des Leuchtmittelsockels in die Leuchtmittelfassung auch bei großen Scheinwerferleistungen und unter schlechten Sichtbedingungen.The solution of the invention ensures a simple design, simple and safe handling and insensitivity to external influences and disturbances correct insertion of the lamp socket in the bulb socket, even with large headlights and under poor visibility conditions.
Durch die kontinuierliche Erfassung der Positionierung eines Leuchtmittelsockels, der in eine Leuchtmittelfassung eingesetzt wird, kann die korrekte Ausrichtung und Verbindung zwischen dem Leuchtmittelsockel und der Leuchtmittelfassung bereits vor dem Erreichen des Endanschlages bzw. Endsitzes des Leuchtmittelsockels in der Leuchtmittelfassung überprüft und gegebenenfalls korrigiert werden. Da mit dem Einsetzen des Leuchtmittelsockels in die Leuchtmittelfassung die Überwachungseinrichtung aktiviert und betätigt wird, kann diese sehr einfach und gegenüber äußeren Einflüssen unempfindlich gestaltet werden, was insbesondere wegen der hohen Temperaturen im Bereich des Leuchtmittelsockels und der Leuchtmittelfassung für einen störungsfreien Betrieb von besonderer Bedeutung ist. Zudem schafft die erfindungsgemäße Überwachungseinrichtung die Voraussetzung für unterschiedliche Ausführungsformen der Überwachungseinrichtung mit jeweils übereinstimmendem Funktionsprinzip.Due to the continuous detection of the positioning of a light bulb socket, which is used in a bulb holder, the correct alignment and connection between the bulb socket and the bulb holder can be checked before reaching the end stop or end seat of the bulb socket in the bulb holder and corrected if necessary. Since the monitoring device is activated and actuated with the onset of the luminous means socket, it can be made very insensitive to external influences, which is of particular importance because of the high temperatures in the region of the luminous means socket and the luminous means holder for trouble-free operation. In addition, the monitoring device according to the invention provides the prerequisite for different embodiments of the monitoring device, each with matching operating principle.
Die erfindungsgemäße Lösung geht dabei von der Überlegung aus, dass die Integration einer Überwachungseinrichtung in einen Scheinwerfer keine Sichtkontrolle von der Licht abgebenden Frontseite des Scheinwerfers erfordelich macht, so dass ein Bediener keinen Mindestabstand von der Frontseite des Scheinwerfergehäuses beim korrekten Einsetzen des Leuchtmittels in die Leuchtmittelfassung des Scheinwerfers einhalten muss, sondern sich auf das Einführen des Leuchtmittels in die Leuchtmittelfassung und Bedienen der Klemmvorrichtung konzentrieren kann. Die Überwachungseinrichtung signalisiert die korrekte Verbindung zwischen dem Leuchtmittelsockel und der Leuchtmittelfassung und damit einen optimalen elektrischen Kontakt der Kontaktstifte mit den Steckbuchsen.The solution according to the invention is based on the consideration that the integration of a monitoring device in a headlight makes no visual inspection of the light emitting front side of the headlamp required, so that an operator no minimum distance from the front of the headlamp housing when correctly inserting the light source in the bulb socket of Headlamps must comply, but on the insertion of the bulb in the bulb holder and Operate the clamping device can concentrate. The monitoring device signals the correct connection between the lamp socket and the lamp holder and thus optimum electrical contact of the pins with the sockets.
Die erfindungsgemäße Überwachungseinrichtung ermöglicht unter Beibehaltung des Funktionsprinzips, die relative Position zumindest eines Teils des Leuchtmittelsockels in Bezug auf die Leuchtmittelfassung beim Einsetzen des Leuchtmittelsockels in die Leuchtmittelfassung zu erfassen, mehrere Ausführungsformen mit unterschiedlicher physikalischer Grundfunktion.The monitoring device according to the invention makes it possible, while maintaining the functional principle, to detect the relative position of at least one part of the luminous means base with respect to the luminous means holder when inserting the luminous means base into the luminous means holder, several embodiments with different basic physical function.
Eine erste Ausführungsform besteht aus einer optischen Positionserfassungseinrichtung mit zwei einander gegenüberliegenden, an den Seitenwänden des Scheinwerfergehäuses und/oder eines Leuchtmittelgehäuses im Bereich der Leuchtmittelfassung angeordneten Inspektionsöffnungen, die mit einander gegenüberliegenden Öffnungen oder Aussparungen der Leuchtmittelfassung fluchten.A first embodiment consists of an optical position detection device with two oppositely disposed, on the side walls of the headlamp housing and / or a light source housing in the region of the bulb socket inspection openings, which are aligned with opposite openings or recesses of the bulb socket.
Diese erste Ausführungsform ermöglicht eine Durchleuchtung der Leuchtmittelfassung über zwei einander gegenüberliegende Öffnungen in der Leuchtmittelfassung und im Scheinwerfergehäuse, so dass ebenfalls eine seitliche Beobachtung der Leuchtmittelfassung und damit Feststellung einer korrekten Verbindung des Leuchtmittelsockels mit der Leuchtmittelfassung ohne Notwendigkeit einer optischen Sichtkontrolle von der Frontseite des Scheinwerfers ermöglicht wird, wobei die erforderlichen Aussparungen oder Öffnungen kleiner als bei der vorstehend genannten Ausführungsform gehalten werden können.This first embodiment allows a transillumination of the bulb holder via two opposing openings in the bulb holder and the headlight housing, so that also allows lateral observation of the bulb socket and thus finding a correct connection of the bulb socket with the bulb holder without the need for optical visual inspection of the front of the headlight is, wherein the required recesses or openings can be kept smaller than in the aforementioned embodiment.
Eine Variante einer optischen Positionserfassungseinrichtung ist durch mindestens einen Lichtleiter gekennzeichnet, der mit einer von zwei einander gegenüberliegenden Öffnungen in der Leuchtmittelfassung und mit einem Kontrollelement verbunden ist, so dass über eine Öffnung Licht in den zu beobachtenden Raum zugeführt und über den Lichtleiter das in den zu beobachtenden Raum eingekoppelte Licht zum Kontrollelement geführt wird bzw. bei vollständig in die Leuchtmittelfassung eingesetztem Leuchtmittelsockel beispielsweise die Lichtzufuhr zum Kontrollelement unterbrochen wird. Weiterhin kann auch die dem einen Lichtleiter gegenüberliegende Öffnung mit einem Licht zum Kontaktbereich zuführenden Lichtleiter verbunden werden, so dass auch die Lichtzufuhr zum zu beobachtenden Raum über einen Lichtleiter erfolgt.A variant of an optical position detection device is characterized by at least one light guide, which is connected to one of two opposing openings in the light-emitting and a control element, so that fed through an opening light in the space to be observed and via the optical fiber in the zu Observing room coupled light is guided to the control element or is interrupted for example completely inserted into the light bulb socket bulb socket, the light supply to the control element. Furthermore, the opening opposite the one optical waveguide can also be connected to a light guide that leads to the contact area, so that the light is also supplied to the room to be observed via an optical waveguide.
Vorzugsweise sind die beiden einander gegenüber liegenden Öffnungen in der Leuchtmittelfassung im Kontaktbereich der Stimseite des Leuchtmittelsockels mit der Leuchtmittelfassung angeordnet.Preferably, the two openings lying opposite one another are arranged in the luminous means holder in the contact region of the end face of the luminous means base with the luminous means holder.
Bei dieser Variante einer optischen Positionserfassungseinrichtung wird die optische Sichtkontrolle des Bedieners durch eine einfache optische Anzeige ersetzt, bei der sich bei korrekt bis zum Anschlag der Leuchtmittelfassung eingesetztem Leuchtmittelsockel die optische Anzeige verdunkelt und dadurch dem Bediener den korrekten Sitz des Leuchtmittelsockels signalisiert. Die optische Anzeige kann bei Bedarf durch eine elektrische Signaleinrichtung ersetzt oder ergänzt werden, indem eine opto-akustischer Wandler verwendet oder hinzugefügt wird. Bei dieser Variante einer optischen Positionserfassungseinrichtung sind jedoch zusätzliche optische und elektronische Bauteile erforderlich.In this variant of an optical position detection device, the optical visual control of the operator is replaced by a simple visual display, in which the optical display darkens when correctly inserted up to the stop of the light bulb socket, thereby signaling the operator the correct fit of the bulb socket. Optionally, the visual display may be replaced or supplemented by an electrical signal device using or adding an opto-acoustic transducer. In this variant of an optical position detection device, however, additional optical and electronic components are required.
Durch die Verbindung der Licht dem Kontaktbereich zuführenden Öffnung oder Aussparung bzw. des Licht dem Kontaktbereich zuführenden Lichtleiters mit einer Licht einkoppelnden Öffnung oder Optik an einer günstigen Stelle an der Außenseite des Scheinwerfergehäuses kann das erforderliche Licht zur Beleuchtung des Verbindungsbereichs zwischen Leuchtmittelsockel und Leuchtmittelfassung eingekoppelt werden.By connecting the light entering the contact area opening or recess or the light supplying the contact area light guide with a light coupling opening or optics at a convenient location on the outside of the headlight housing, the required light for lighting the connection area between the light bulb socket and bulb holder can be coupled.
Alternativ kann die Licht zum Kontaktbereich zuführende Öffnung oder Aussparung oder der Licht zuführende Lichtleiter mit einer Hilfslampe zur Beleuchtung bzw. Durchleuchtung des zu beobachtenden Raums in der Leuchtmittelfassung verbunden werden, so dass mit der Hilfslampe Licht in den Lichtleiter eingekoppelt wird, die den betreffenden Bereich der Leuchtmittelfassung auch ohne externes Licht, d.h. auch bei völliger Finsternis beleuchtet und damit eine optische oder akustische Überprüfung des korrekten Sitzes des Leuchtmittelsockels gewährleistet.Alternatively, the light to the contact area supplying opening or recess or the light-supplying light guide can be connected to an auxiliary lamp for illumination or fluoroscopy of the space to be observed in the bulb holder, so that is coupled with the auxiliary lamp light in the light guide, the relevant area of the Bulb holder even without external light, ie illuminated even in complete darkness and thus ensures a visual or audible verification of the correct fit of the bulb socket.
Das Kontrollelement kann alternativ aus einer am Scheinwerfergehäuse angeordneten Einblicköffnung oder Einblickoptik oder aus einem mit dem Scheinwerfergehäuse verbundenen opto-elektronischen Wandler und einer optischen und/oder akustischen Signaleinrichtung bestehen und die Lichtleiter als Glas- oder Glaskeramik-Lichtleiter ausgebildet sein.Alternatively, the control element may consist of an inspection opening or viewing optics arranged on the headlight housing or of one with the headlight housing connected opto-electronic converter and an optical and / or acoustic signal means exist and the light guides may be formed as a glass or glass ceramic light guide.
Anstelle einer optischen Positionserfassungseinrichtung kann eine mechanische Positionserfassungseinrichtung mit einem in die Leuchtmittelfassung eingesetzten und mit einer Anzeigeeinrichtung verbundenen mechanischen Sensor vorgesehen werden.Instead of an optical position detection device, a mechanical position detection device can be provided with a mechanical sensor inserted into the light-emitting means holder and connected to a display device.
Diese Ausführung ermöglicht mit einfachen mechanischen Mitteln eine Anzeige zur Überprüfung des korrekten Sitzes eines Leuchtmittels in einer Leuchtmittelfassung, ohne dass es erforderlich ist, dass der Bediener beim Einsetzen des Leuchtmittels vor dem Scheinwerfer steht. Gleichzeitig gewährleistet die mechanische Positionserfassungseinrichtung insbesondere in Verbindung mit einer mechanischen Anzeigeeinrichtung die Überprüfung des korrekten Sitzes des Leuchtmittels in der Leuchtmittelfassung auch bei schlechtesten Sichtbedingungen bereits während des Einsetzens des Leuchtmittelsockels in die Leuchtmittelfassung, wobei der Sensor aus einem in die Leuchtmittelfassung ragenden und beim Einsetzen des Leuchtmittelsockels verschiebbaren und mit einem Indikatorhebel verbundenen Taststift besteht.This design allows by simple mechanical means a display for checking the correct fit of a bulb in a bulb socket, without it being necessary for the operator to stand in front of the headlight when inserting the bulb. At the same time, the mechanical position detection device, in particular in conjunction with a mechanical display device, ensures the correct seating of the luminous means in the luminous means holder even during the worst viewing conditions during the insertion of the luminous means socket into the luminous means holder, wherein the sensor consists of one protruding into the luminous means holder and on insertion of the illuminant base slidable and connected to an indicator lever stylus is.
In dieser Ausführungsform wird der korrekte Sitz des Leuchtmittels in der Leuchtmittelfassung nicht mehr nur optisch durch eine Sichtkontrolle überprüft, sondern kann durch alleiniges Abtasten der Position des Indikatorhebels bereits während des Einsetzens des Leuchtmittelsockels in die Leuchtmittelfassung erfolgen, so dass die Überprüfung des korrekten Sitzes auch bei Dunkelheit oder unter sehr schlechten Sichtbedingungen erfolgen kann. Gleichzeitig zeichnet sich diese Ausführungsform durch ihre einfache Mechanik bei hoher Zuverlässigkeit aus.In this embodiment, the correct fit of the light source in the light-emitting socket is not only visually checked by a visual inspection, but can be done by solely scanning the position of the indicator lever already during insertion of the lamp socket in the bulb socket, so that the verification of the correct fit even at Darkness or under very poor visibility conditions. At the same time, this embodiment is characterized by its simple mechanism with high reliability.
Vorzugsweise ist der Taststift zu dem der Einsatzöffnung der Leuchtmittelfassung entgegen gesetzten Ende der Leuchtmittelfassung geführt und liegt an einem ersten Hebelarm des drehbar gelagerten und federbelasteten Indikatorhebels an, dessen zweiter Hebelarm durch eine Öffnung eines die Leuchtmittelfassung aufnehmenden Fassungsträgers und/oder Leuchtmittelgehäuses geführt ist.Preferably, the stylus is guided to the insertion opening of the bulb holder opposite end of the bulb holder and is applied to a first lever arm of the rotatably mounted and spring-loaded indicator lever, the second lever arm is guided through an opening of the bulb holder receiving socket carrier and / or light source.
Der zweite, als Zeiger dienende Hebelarm ist vorzugsweise länger als der erste, den Taststift kontaktierende Hebelarm, wodurch eine größere Auslenkung des als Zeiger dienenden ersten Hebelarms zur Verbesserung der Genauigkeit der Anzeige gewährleistet ist.The second, serving as a pointer lever arm is preferably longer than the first, the stylus contacting lever arm, whereby a greater deflection of the serving as a pointer first lever arm is guaranteed to improve the accuracy of the display.
Zur Anzeige des korrekten Sitzes des Leuchtmittelsockels in der Leuchtmittelfassung kann in einer ersten Ausführungsform der zweite Hebelarm des Indikatorhebels in einem Formteil des Fassungsträgers oder des Leuchtmittelgehäuses angeordnet werden, das eine mit der Verschiebung des Taststiftes beim Einsetzen des Leuchtmittelsockels in die Leuchtmittelfassung korrelierende Markierung aufweist. In dieser Ausführungsform kann die Markierung aus einem Endanschlag einer den zweiten Hebelarm des Indikatorhebels aufnehmenden Aussparung bestehen.To display the correct seating of the luminous means base in the luminous means holder, in a first embodiment the second lever arm of the indicator lever can be arranged in a shaped part of the holder or of the illuminant housing which has a marking correlating with the displacement of the stylus when the illuminant base is inserted into the illuminant holder. In this embodiment, the marking may consist of an end stop of a recess receiving the second lever arm of the indicator lever.
Alternativ kann die Markierung aus einer mit der Kontur des Endes des Indikatorhebels übereinstimmenden Nase bestehen, die mit der Richtung der Auslenkung des Indikatorhebels bei vollständig in die Leuchtmittelfassung eingefügtem Leuchtmittelsockel fluchtet.Alternatively, the marking may consist of a matching with the contour of the end of the indicator lever nose, which is aligned with the direction of the deflection of the indicator lever with fully inserted into the bulb socket bulb socket.
Um sicherzustellen, dass der Leuchtmittelsockel mit dem Taststift in Kontakt kommt, ist das in die Einführöffnung der Leuchtmittelfassung ragende Ende des Taststiftes derart ausgebildet, dass es beim Einführen des Leuchtmittelsockels in die Leuchtmittelfassung an einen Teil der Leuchtmittelfassung anschlägt, wobei die Fläche des in die Einführöffnung der Leuchtmittelfassung ragenden Endes des Taststiftes größer ist als der Durchmesser des Taststiftes.To ensure that the bulb socket comes into contact with the stylus, the projecting into the insertion of the bulb holder end of the stylus is designed such that it abuts when inserting the bulb socket in the bulb holder to a portion of the bulb socket, the surface of the insertion into the the bulb holder projecting end of the stylus is greater than the diameter of the stylus.
In einer konkreten Ausführungsform weist der Taststift einen in die Einführöffnung der Leuchtmittelfassung ragenden haken- oder pilzförmigen Vorsprung auf, der bei in die Leuchtmittelfassung eingesetztem Leuchtmittelsockel in eine Aussparung der Leuchtmittelfassung verschiebbar ist, und besteht aus Keramik, Glaskeramik oder Glas.In a specific embodiment, the stylus has a hook-shaped or mushroom-shaped projection projecting into the insertion opening of the luminous element holder, which can be displaced into a recess of the luminous element holder when the luminous means socket is inserted into the luminous means holder, and consists of ceramic, glass ceramic or glass.
In einer weiteren alternativen Ausführungsform besteht der Taststift aus einem frei schwimmend in dem Leuchtmittelgehäuse und/oder der Leuchtmittelfassung gelagerten und in mindestens einer Aussparung des Leuchtmittelgehäuses und/oder der Leuchtmittelfassung geführten Keramikhebel, der mit einem außerhalb des Leuchtmittelgehäuses und/oder der Leuchtmittelfassung angeordneten Indikatorhebel verbunden ist.In a further alternative embodiment, the stylus consists of a free-floating in the lamp housing and / or the bulb holder and guided in at least one recess of the lamp housing and / or the Leuchtmittelfassung ceramic lever connected to an outside of the lamp housing and / or the bulb socket indicator lever is.
Diese besonders einfache Ausführungsform ist hochtemperaturbeständig und gewährleistet auch unter extremen äußeren Bedingungen eine korrekte Funktion, da wegen der frei schwimmenden Lagerung des Keramikhebels kein Verkanten auftritt, so dass der Keramikhebel beim Einsetzen des Leuchtmittels durch den Leuchtmittelsockel verstellt wird und der aus der Leuchtmittelfassung herausragende, mit dem Keramikhebel verbundene Indikatorhebel die jeweilige relative Position des Leuchtmittelsockels in Bezug auf die Leuchtmittelfassung auch ohne Sichtkontakt anzeigt.This particularly simple embodiment is resistant to high temperatures and ensures a correct function even under extreme external conditions, since due to the free-floating mounting of the ceramic lever no tilting occurs, so that the ceramic lever is adjusted when inserting the light source through the bulb socket and the outstanding from the bulb holder, with Indicator lever connected to the ceramic lever indicates the respective relative position of the lamp socket with respect to the bulb socket without visual contact.
Diese Merkmale einer mechanischen Positionserfassungseinrichtung gewährleisten zum einen, dass die Isolationswirkung der Leuchtmittelfassung erhalten bleibt und nicht die notwendigen Kriech- und Luftstrecken beeinträchtigt werden, da der im Gefahrenbereich liegende Teil des Mechanismus der mechanischen Positionserfassungseinrichtung aus einem Hochtemperatur-Isolator besteht und zum anderen ein großer Indikatorhebel einsetzbar ist, durch den der korrekte Sitz des Leuchtmittelsockels in der Leuchtmittelfassung äußerst exakt angezeigt und bedarfsweise auch mit zusätzlichen Signalisierungseinrichtungen gekoppelt werden kann, die den korrekten Sitz zuverlässig und reproduzierbar angeben.These features of a mechanical position detection device ensure, on the one hand, that the insulating effect of the illuminant holder is maintained and the necessary creepage and clearance distances are not impaired, since the part of the mechanism of the mechanical position detecting device lying in the danger zone consists of a high-temperature insulator and, on the other hand, a large indicator lever can be used by the correct fit of the bulb socket in the bulb holder extremely accurately displayed and, if necessary, can also be coupled with additional signaling devices that indicate the correct fit reliable and reproducible.

Das Leuchtmittelgehäuse 5 enthält eine Leuchtmittelfassung 7 mit Steckbuchsen zur Stromzufuhr, in die die Kontaktstifte des Leuchtmittels 4 eingesetzt werden, das einen länglichen, gasgefüllten Glaskörper 41 und einen Leuchtmittelsockel 42 mit den Kontaktstiften aufweist.The
Zur Reduktion bzw. Beseitigung der auf die Kontaktstifte auf Grund der Länge des Glaskörpers 41 sowie dessen Gewicht und des Gewichts des Leuchtmittelsockels 42 auf die Kontaktstifte des Leuchtmittels einwirkenden Kräfte, die in das Leuchtmittelinnere übertragen werden und dort zu unzulässigen Spannungen und einen Ausfall des Leuchtmittels führen und den elektrischen Kontakt zwischen den Kontaktstiften und den Steckbuchsen 81, 82 der Leuchtmittelfassung 7 beeinträchtigen können, sowie zur verbesserten Halterung und Klemmung des Leuchtmittels 4 ist eine Klemmvorrichtung 6 mit zwei Klemmbacken 61, 62 vorgesehen, die den Leuchtmittelsockel axial zueinander beabstandet umfassen und kraft- und/oder formschlüssig einklemmen. Die obere Klemmbacke 61 und die untere Klemmbacke 62 sind jeweils mit zwei Hebelarmen verbunden, die an ihrem den Klemmbacken 61, 62 entgegengesetzten Enden über Querstege miteinander verbunden sind und flächig an der Leuchtmittelfassung 7 anliegen. Parallel zu den Querstegen sind Verbindungsstangen zwischen den Hebelarmen der oberen und unteren Klemmbacke 61, 62 vorgesehen, die über federelastische Abstützungen mit dem Fassungsträger 5 verbunden sind.To reduce or eliminate the force acting on the pins due to the length of the
Durch die federnde Lagerung der Hebelarme und damit der Klemmbacken 61, 62 wird bei einer beispielsweise durch Stöße hervorgerufenen Bewegung des Leuchtmittels 4 die Aufnahmevorrichtung in der gleichen Ebene mitbewegt, so dass die Kontaktstifte frei von Spannungen bleiben. Durch eine ebenfalls elastische Abstützung der Leuchtmittelfassung 7 über eine Federlagerung gegenüber dem Fassungsträger 5 wird sichergestellt, dass keine Kräfte auf die Kontaktstifte des Leuchtmittels 4 übertragen werden, so dass die Kontaktstifte zur ausschließlichen Übertragung der elektrischen Leistung dienen.Due to the resilient mounting of the lever arms and thus of the clamping
Zum Verstellen der Klemmbacken 61, 62 von einer Öffnungsstellung, in der der Leuchtmittelsockel 42 zur Entnahme des Leuchtmittels 4 freigegeben wird, in eine Schließund/oder Verriegelungsstellung, in der die Klemmbacken 61, 62 den Leuchtmittelsockel 42 einspannen und das Leuchtmittel 4 in seiner Lage fixieren, dient eine Verstelleinrichtung 63 mit einem auf die Hebelarme einwirkenden Verstellglied und einem Betätigungsglied zur manuellen Betätigung der Verstelleinrichtung 63.For adjusting the clamping
Zum Einsetzen oder Austauschen eines Leuchtmittels werden die Klemmbacken 61, 62 mittels der Verstelleinrichtung 63 geöffnet und das Leuchtmittel 4 durch die trapezförmige Öffnung der voneinander getrennten Klemmbacken 61, 62 von der Frontseite des Scheinwerfers mit seinem Leuchtmittelsockel 42 in die Leuchtmittelfassung 7 und dabei die Kontaktstifte des Leuchtmittels 4 in die Steckbuchsen 81, 82 der Leuchtmittelfassung 7 eingesetzt. Nur bei gerade in die Leuchtmittelfassung 7 eingesetztem Leuchtmittelsockel 42 ist aber zum einen eine zentrische Anordnung des Leuchtmittels 4 in der Leuchtmittelfassung 7 zwischen den Klemmbacken 61, 62 der Klemmvorrichtung 6 und zum anderen eine optimaler elektrischer Kontakt zwischen den Kontaktstiften des Leuchtmittels 4 und den Steckbuchsen 81, 82 der Leuchtmittelfassung 7 zur Vermeidung von Schäden durch Bruch, elektrischen Überschlägen oder Kontaktkorrosion gewährleistet.To insert or replace a bulb, the
