Description

Lamp, industrial device, power rail, damper device and power rail adapter. The invention relates in a first place to a lamp according to the main passage of the first claim. Such lamps are known and very popular. They are manufactured by the applicant for decades. For example, reference is made to a "Focalflood" lamp that is described in the current catalog of the applicant, edition 2004/2005 on page 486 et seq., Which has several lighting elements of different colors. The lighting elements are connected to voltage supply lines, which make available the supply or operational voltage for the lighting elements. In addition, the lamp has three electronic pre-connection devices, so that the three lighting elements are individually operable. The pre-connection device can be, for example, a pre-connection device which operates according to the so-called DALÍ protocol, which is individually steerable and which is connected to a signal line. The lamp can be incorporated in a network of lamps and can receive control information through the signal line through a central control system. Thus, for example, from the central control system, the information can be transmitted to one of the lighting elements of the lamp to enter a "dimming" determination, also determined, for example, in order to mix the colors , to flash, to connect, to disconnect or similar operations. The voltage or voltage supply line, to which a phase conductor as well as a zero conductor usually belongs, is typically connected through a first connection to the lamp and transmits, for example, an operating voltage of 230 ° or alternating current. respectively 110 V. For the connection of the signal line, a second connection is provided in the lamp or respectively in the operating device corresponding to the lamp, ie, for example, the previous electronic connection device. The signal line is typically a line of two wires or webs through which the voltages can be transmitted up to 25 V, for example. The signal line is separated in the normal case separately from the voltage supply lines. Starting from a lamp according to the main fragment contained in the first claim, it is the task of the present invention to provide a lamp, which offers greater security, against mounting faults. The invention solves this task by means of the features indicated in the first claim, particularly those contained in the characterizing part, and therefore it is identified because the second connection is assigned a fuse or protection against an excess voltage, which is configured interchangeably or switchably. The principle of the present invention therefore lies fundamentally in providing a fuse that can be turned off at the time of exceeding a theoretical voltage. In case of a faulty assembly, that is to say a faulty connection of the lines, so that it is presented in the second connection for the signal line in the wrong way, the operating voltage clearly greater, then it can be interrupted or the fuse. When the fuse is advantageously formed as a melting fuse, the melting wire can be melted as a result of heating to protect the lamp arranged in the direction of the current behind the fuse or, if appropriate, the operating device of the lamp, as well as also the electronic system that is in that unit, against an excess of voltage, due to the interruption of the circuit of the current. When on the other hand the high operating voltage from for example 230 V would impinge on a high-voltage transformerfor example 12 V, could be developed for example a copper vapor, which in addition to certain direct damage to the health of the assemblers, could also have a disadvantageous influence on the electric and electronic parts of the lamp in case they were configured certain parts or insulating surfaces of the unit, in a conductive condition, as a result of precipitation of the copper vapor, which could give rise to greater indirect damages. Other harmful effects are also possible in parts of the lamp or in the operating apparatus. The fuse, in the case of an interruption trip, as for example in the case of a fusion fuse, is configured interchangeably. For this purpose, a melting fuse is advantageously mounted in an easily accessible place of the lamp and, for example, by means of traditional spring terminals it could be held and after firing it could be replaced by a new fuse. As an alternative, the fuse can also be structured in a switchable manner, so that it triggers automatically in the detection of an excessive voltage of greater than some theoretical voltage, so that either manually it could be returned from its interrupted condition, from a cut-off situation. of the current to a conductive condition of the latter, or a return system of the switching may also be brought about, for example after a certain period has elapsed. It is of fundamental importance that the fuse responds very quickly and in its interrupted or triggered condition it safely and permanently stops the voltages raised up to the size of 400 V. This resistance to the high cut of the fuse fired is necessary in those cases in which two phase conductors of different potential are connected to the second connection instead of two signal lines. The fuse is particularly advantageous when the lamp must be connected to a power rail. The fuse, in case of a defective assembly and a fault in the conductors, inside the current lane, could thus fire in a safe way to protect in this way the lamp itself or in its case the operating apparatus of the same. The placement of the interchangeable fuse or a manual switchable return fuse in some easily accessible place may mean, for example, that only a part of the lamp's camera or an operating device of the lamp must be removed, in which case, after If said part of the chamber is removed, a support apparatus for the fusion fuse is accessible so that the fuse can then be removed to be replaced by a new device. According to an advantageous configuration, the invention is placed next to the lamp an operating device, where the first connection and / or the second connection is mounted. As an operating device of the lamp, for example, an electronic pre-connection device, a transformer or some other device immediately applied to the lamp is identified, with which the functioning thereof can be directed. The operating apparatus is typically placed in the immediate vicinity of the lamp and can be located, for example, in the chamber thereof or in a separate operating device chamber. For the case in which the lamp is connected through a current lane sideboard, to the lane itself, the operating device can also be found inside a camera of the current lane adapter. In accordance with an advantageous configuration of the invention, two inputs for signal lines are mounted adjacent to the second connection, which are short-circuited via an electronic construction element, particularly through a varistor, so that when a certain value is exceeded The theoretical voltage causes a large current flow between the two inputs, as a result of the presence of the fuse. This current flow can trigger the fuse. While in the case of low voltages, that is, in the case of a usual connection, when the electronic construction element is not in a prominent place, for example because its electrical resistance is very high so that it does not pass through an electronic construction element, in a normal case , no current, when this theoretical voltage is exceeded, that is, in the case of a defective assembly, a current can actually pass through the electronic construction element because, due to the high voltage, for example, above a critical level of 60 V , decrease the electrical resistance by the construction element. Such a known construction element is for example a Varistor (ie a variable resistance). When by mistake in the case of a defective assembly in place of the signal line a pair of phase conductors is connected to the second connection, due to the large current flow through the electronic construction element a corresponding current flow is also caused through the fuse. In the case of a melting fuse, this large current flow due to the ohmic heat leads to melting of the melting conductor and to a fuse trip. As soon as the fuse trips and the current circuit is interrupted, the electronic system of the operating device and the lamp is protected against excess voltage, which is placed in the direction of the current, behind the fuse, in such a way that that no damage is caused to these construction parts. After firing the fuse, you only have to change the part or, if necessary, return your connection system, but not the operating device that fundamentally has a higher value or the lamp itself that will also be more expensive. According to an advantageous configuration of the invention, the fuse is triggered only above a voltage of 30 V or 50 V, particularly above 230 V, and then very particularly above 300 V. This configuration of the invention considers firstly that the control information transferred through the signal line has only reduced voltages of less than 30 V, in any case less than 230 V. For the case that instead of two lines of signals, by mistake they are placed in the Second connection Two phase conductors, voltage amplitudes of more than 400 V can be produced so that the fuse and also the Varistor must be corrected accordingly. The voltage, above which the fuse blows, must be chosen in accordance with the present invention in such a way that it is situated above that usable voltage for the transfer of the control information in addition to a certain margin in order to compensate tolerances, for example in the magnitude of the order of a few volts or several tens of volts. In accordance with another advantageous configuration of the invention, the control information corresponds to the so-called DALÍ protocol ("Digital Addressable Lighting Interface") This protocol developed by the DALI working association within the Central Federation of German Industry of Electrotechnical and Electronic, non-profit society (in German: "Zentralverband der deutschen Elektrotechnik- und Elektronikindustrie eV) (abbreviation in German: ZVEI) as described for example in every detail in the previously published manual of DALÍ, of the company DALÍ AG , 2nd edition, 2001, editor Richard Pflaum Verlag, Munich. The invention further relates to an operating apparatus for a lamp, especially an electronic type pre-connection apparatus, according to the main part of claim 6. Such an operating device can be part of a lamp or it can also be placed separately from the lamp for example near it. In addition to electronic pre-connection devices, other devices for a lamp are also considered, as an operating device, with which the lamp can be dimmed or gradually switched on and off, or it can also be switched on or off directly or with which the irradiation behavior or, where appropriate, the color of the light can be influenced or it can be worked on on some element of lighting the lamp. An operating apparatus according to the state of the art typically has a first connection for its connection to a voltage supply line, with which the supply voltage for operating a lighting element of the lamp can be transferred. The operating device also has a second connection for a signal line with which the control information can be transferred in order to direct the lamp. The control information can be configured, for example, with the so-called DALY protocol. An output of the operating device is typically connected to the lighting element so that depending on the control information or, where appropriate, control commands, a corresponding control of the lighting element or the element itself can be created for the operating device. Starting from this state of the art consists the task of the present invention in the system according to which by the previous public use of an operating device thus disclosed according to the main concept of claim 6 its operation can be improved thanks which will achieve greater security in the face of failures during assembly. The invention solves this task with the features set forth in claim 6, particularly with that of the characterizing part, and is also typified because next to the second connection a fuse is mounted against an excess of voltage that can be configured interchangeably or connectable. In order to avoid repetitions, reference is made to the explanations indicated above in relation to claims 1 to 5, in which the references, the descriptions and the advantages that refer thereto to a single lamp now analogously refer to the operating device for said lamp. . The fuse corresponds to that previously described in relation to a lamp. It is again interchangeable or connectable type. The fuse can be incorporated directly into the operating device or it can also be mounted in front / of the same. The invention also relates to a current rail according to the main concept of claim 10. Such a current rail is known, for example, from the German memory DE 100 25 646 Al. The known current rail has voltage supply lines (Phases). Standard 1, 2 and 3), that is to say phase conductors that serve to supply the operating voltage to a lamp. In addition, the current rail also has control lines which can be used to control the light and which therefore constitute signal lines according to the main concept of claim 10, through which control information can be transmitted to the lamp. The lamp has a first connection through which it can be connected to the phase conductor of the current rail as well as through at least one second connection through which it can be connected to the signal line of the rail. The two connections to the lamp correspond, of course, to the points of contact within the conductor lanes of the current lane. The lamp can again have an operating device which, due to a reception of control information, can be directed correspondingly to the lighting element. As an alternative to an arrangement of the operating apparatus within the lamp, the operating apparatus can also be applied to the lamp, by means of the two connections. Starting from the previously known current lane lies the task of the invention to improve a current rail according to the main concept of claim 10 in such a way that it will better protect the lamp or the operating device for the lamp, against the consequences of a defective assembly or an incorrect connection to the current lane. The invention solves this task by the features set forth in claim 10, particularly with those contained in the characterizing part and therefore is typified because next to the second connection is placed a fuse that protects against excessive voltage, which is configured interchangeably or switchable. To avoid repetitions, reference is made to the above explanations which refers to the content of claims 1 to 5, in which reference has been made to the references, descriptions and advantages insofar as they refer to a lamp, analogously , they also apply to the current rail according to the present invention, to which a lamp or an operating device is connected. A fundamental advantage of the current rail according to the invention is that in a traditional current rail, which for example consists of three phase conductors and a zero conductor, a lamp can now be connected to receive its send information through a line of signals, without failures in the assembly generate aggravating consequences. The provision of a fuse against excess voltage, which is configured interchangeably or connectable, thus makes it possible to protect the most expensive operating devices or, if applicable, the lamp itself in case of an excess of voltage caused by a mounting fault. By exchanging the fuse or the changeable return of the fuse from the triggered state to a rest condition, in which it becomes conductive, after the corrected assembly without major expense the operating capacity of the lamp can be restored, if necessary , of the operating device. The fuse can also be mounted here in the current rail or directly or indirectly in a fixed manner in an adapter or similar part, which is connected to the current rail. The invention also relates to a switching device according to the main concept of claim 14. The purpose of this invention is to configure a switching system for a lamp or for an operating device or in its case a current rail, which will not jump at sight, in relation to some defective assembly. The invention solves this problem with the typical features of claim 14, particularly with those contained in the characterizing part, and therefore stands out because next to the second connection is mounted a fuse against excess voltage, which is configured interchangeably or switchable. The principle and advantages of this invention are understood in the best way taking into account the principle of the invention indicated under reference to a lamp and taking into account the content of claims 1 to 5 in order to avoid repetitions is referred to the explanations indicated above which also refer analogously to a switching system or device.

The switching device according to the invention can also be manufactured separately from a lamp or from an operating device or, where appropriate, from a current rail, and can be connected, a separate construction element to a lamp or, where appropriate, to a operating device, or also to a current lane. The invention also relates to a current rail according to the main concept of claim 18. The current rail is known, for example, under the identification of a three-phase current rail for decades, by the applicant himself. It typically comprises three phase conductors and a zero conductor through which part a lamp or several lamps can be supplied with the operating voltage. For this purpose, a current rail adapter is typically used within the rail configured as a U-profile and is locked mechanically and electrically with the current rail. The different phase conductors can optionally come into contact in order to connect the lamp to, for example, a group of lamps that can be directed as a set of lamps. The purpose of the present invention is to improve the known current rail in such a way that the control of the lamps is simplified.

The invention solves this task with the features set forth in claim 18, particularly those established in the characterizing part and therefore is typified because it is provided with a mounting system that switches one or both conductors as a signal line for the provision of information of control to the lamp. The principle of the invention basically consists in connecting a traditional current rail, for example a three-phase current rail by means of a connection system in such a way that one or more of the present conductors, preferably two conductors, can be used in a traditional manner , for the purpose of supplying the lamp with voltage, in which case at least one and preferably two of the present drivers will be used in a novel way as a signal line for supplying control information to the lamp. By means of the arrangement of the connection system it is also possible to use the fixedly installed current lanes, for example in a building, that is already present, for the purpose of controlling lamps having, for example, a DALÍ type pre-connection device or an apparatus operative DALÍ. DALÍ lamps can obtain their control information through the current current lane without having to install additional lines.

Therefore, the expense for the installation concept is very low, only another wiring of the current lane is required. It can therefore be said that the three-phase current rails already present can be retrofitted in a simple manner. The new connection system provided can, for example, comprise a switching part that connects one end of the current rail to a central control for a network of lamps. The invention makes possible the reuse of current rail systems already present, which only need to be connected in a different way to the traditional one, in which the current rail does not have its three phase conductors and a zero conductor but with a conductor zero is attached to a phase conductor as well as to a control unit of the DALÍ type network or another type of network. In accordance with an advantageous embodiment of the invention, a marker element is mounted on the current rail which shows that one of the conductors is used for the transfer of control information. This allows a particularly simple form of indication to indicate in which mode the current lane is located or in what way that lane has just been switched. The person who wishes to attach a lamp to the current lane, it can be ensured in this way without delay and certainly if the current rail is mounted as a traditional three-phase current rail or in a manner according to the invention as a single-phase current rail having two control lines. The marker element can also be detachably attached to the current rail, which is an advantageous feature so that it can be used as an additional element or as an accessory. Another advantageous aspect is that the marker element can be joined by means of a clip or by means of a clip for immediate connection to the current rail, so that without the application of particular auxiliaries a mounting of the marker element to the current rail can be carried out. Finally, the invention relates to an adapter for a current rail according to the main concept of claim 25. Such a current adapter is known, for example, from DE 103 12 012 Al of the applicant, whose document is made reference for the purpose of avoiding repetitions and whose content may also be incorporated herein for the purpose of making reference to the characteristics or groups of individual characteristics, within the content of the present patent application. The adapter for a known current rail serves for the mechanical and electrical connection of a lamp to a current rail. The adapter can be used by the same system, if an operating device is present, also for the mechanical and electrical connection of the operating device as well as possibly for the lamp at the same time, in order to connect it to the current rail. The operating device itself can also be incorporated into the camera of the current-path adapter for this purpose, for example. The known adapter of the current rail as proposed by the applicant can be advantageously applied already with a very small number of construction parts or module, allowing a particularly simple assembly. The known current rail adapter has for this purpose a first and a second arrow or switching shaft which have, on one side, a contact tongue of the phase conductor and, on the other hand, a contact wire of the zero conductor, with which the driver lanes can be communicated within the current lane. Starting from this current state of the art, it is the task of the present invention to improve a current rail adapter according to the main concept of claim 1 in such a way that together with a simple structure it can also be attached to the rail current a lamp that has a first connection to join a voltage supply line and a second connection that serves to connect to a signal line. The invention solves this task with the features contained in claim 25, particularly those contained in the characterizing part and therefore stands out because each arrow or connecting shaft has two contact elements rotatably attached to the switch shaft. The principle of the invention fundamentally lies in assigning to the switching arrows, in each case, two contact elements. All the contact elements, despite the very restricted space conditions, can be accommodated within the switching arrows, thanks to a suitable arrangement. Each contact element has a plug element, preferably a plug tab. The plug element can be connected to a connection conductor, which has an opposite plug element. The opposite plug element can be a flat plug wrap. The plug element, preferably of each plug element, is mounted in the vicinity of the pivot axis of the switch shaft. The plug element is also straightened, preferably from each plug element, basically along the axis of pivoting or turning of the corresponding switching arrow, that is, in a direction parallel to the axis of turn. Thanks to this arrangement, the bending stress of the connection conductor can be kept very low thanks to a turning or rotating movement of the switching shaft. This virtually excludes damage caused to the connection conductors. In view of the fact that two contact elements are associated with each switching arrow, one can be based on the traditional construction. of the adapter described in the German report DE 103 12 012 Al. Each switching shaft has a rotary axis, which in the assembled position is basically straight in a perpendicular direction on the longitudinal section of the current rail. The drive planes for carrying out a rotary movement of each switching arrow are therefore outside the interior space of the current rail to allow a suitable contact by a user with the possibility of transferring large moments of rotation. Typically, the drive planes are mounted on a wider axial section of each switch shaft or on a separate drive lever.

The division in pairs of the four required contact elements that serve for the communication of a zero conductor, a phase conductor and two signal lines in two separate switching arrows makes possible the need for reduced manipulation forces that serve to carry out a rotary movement of the commutator arrows. In contrast to a current rail adapter of the applicant which has been disclosed by means of a public previous use, in that by means of an actuator cylinder which can be rotated about an axis of rotation extended in the longitudinal direction of the current rail and in which, due to the rotation of the actuating cylinders, four contacts can be removed simultaneously, in the construction according to the invention, which provides two switching arrows for two contact elements in each case, the forces are reduced, so to speak, by half of handling, which facilitates handling. Furthermore, thanks to the presence of two switching arrows, it is possible to block the switching arrows in interrelation so that first a switching arrow can first be actuated when a second switching arrow has already been activated, as already happens in the case of the second switching arrow. case of the known current rail adapter according to DE 103 12 012 Al of the applicant. Advantageously, the current rail adapter has a common output for all four or more connection conductors. Here, it is also advantageous when a switching arrow, where two contact elements are mounted, has a passage channel at least for two other connection conductors, a contact of the two connection conductors now occurs with the plug elements of the connection elements. contact of the other switching arrow. In addition, it is advantageous when the plug elements of a first switching arrow, for example of the switch shaft having the contact elements for communication of the signal lines, in the assembled state of the current rail adapter point towards the base of the switch. current rail, while on the other hand the plug elements of the contact elements of the other switch arrow point away from the base of the current rail. This makes possible a particularly advantageous guidance or guidance of the connection lines within the adapter of the current rail and thus also creates the simple possibility of mounting a common output for all connection lines, within the adapter of the current rails. Due to the mounting of plug elements in the contact elements, the assembly of this adapter for current rails can be carried out in a simple manner. In addition, the current rail adapter can be manufactured with a very small number of modules or building elements. It is surprising that despite the reduced conditions of space available in the switch shaft due to the dimensions provided by the insertion slot within the current rail, an arrangement of two contact elements in a switch shaft is possible. Advantageously, the two contact elements are separated from each other, in each case, by some plastic or other material, electrically insulating. Other advantages of the invention result from the secondary claims not mentioned as well as on the basis of the following description of exemplary embodiments shown in the figures. In the figures: Figure 1 presents in a partially cut-away and schematic view a traditional three-phase current rail according to the current state of the art, which in the manner explained in this invention can also be switched for the transfer of command information.

First and starting from Figure 3, an example of realization of a lamp according to the invention identified in its entirety must be explained with the number 10. It is pointed out that in the following description of the figures, equal or comparable parts or similar elements for greater clarity carry the same references, partially under the addition of lowercase letters. The lamp according to the invention comprises in its traditional structure a chamber 11, in which interior space 12 a lighting element 13 is fixedly mounted. The lighting element, which can be, for example, an incandescent light bulb, is supplied with an operating voltage a through two input lines indicated schematically 14a and 14b. The input lines communicate the lighting element 13 to an operating device 15 indicated schematically, for the lighting element, for example in the form of an electronic pre-connection device. For this purpose, the electronic pre-connection device 15 has, in addition to the output 16 for the connection of the input lines 14a and 14b, a first connection 17 for connection to the voltage supply lines 19a and 19b as well as a second connection 18 for joining the operating device 15 and consequently the lamp 10 with signal lines 20a and 20b. The second connection 18 thus belongs not only to the operating device 15 but also to the lamp 10. The lamp indicated in Figure 3 corresponds from its basic structure to the current state of the art, but contains an interchangeable fuse illustrated below . For the invention it does not matter how many lighting elements 13 or respectively how many operating apparatuses 15 are applied to the lamp 10. It is also conceivable that different lighting elements, of different colors, can be mounted on a lamp and that they can be supplied from an apparatus or several operating devices. In the same way, the lamps according to the invention 10 or the operating apparatuses according to the invention 15 can have the same, also several first connections 17 and several second connections 18. Figure 4 shows, in the form of a block diagram representation, of schematic type, a traditional operating device 15 ', according to the configuration of an electronic pre-connection apparatus, which completed with a signal circuit 21 can be used as an operating apparatus according to the invention, 15, inside the lamp 10, as illustrated in Figure 3. The operating apparatus identified in Figure 4 with 15 'is therefore an operating apparatus according to the current state of the art that has an output 16 for the input lines 14a, 14b to the lighting element, 13, a first connection 17 with two connection points 23a and 23b for communication with the voltage supply lines 19a and 19b as well as a second connection 18 'with two connection points 22a and 22b, and that the traditional operating device 15 'serves for communication with the signal lines 20a and 20b. The connection points 22a, 22b therefore constitute the inputs of a traditional electronic pre-connection device 15 '. In front of the second connection 18 'of the traditional pre-connecting device 15' is placed on the input side, the switching system 21, which has an interchangeable fuse 25 between the connection points 24b and 22b and a Varistor 26 mounted in parallel with respect to the two connection points 22a and 22b, ie a variable resistance. To the connection points 24a and 24b of the connection system 21, the signal lines 20a and 20b are connected to the lamp according to the invention 10 or respectively in an operating device according to the invention 15. As long as through the voltage supply lines 19a and 19b, the operating voltage is supplied to the lamp 10, which can be, for example, an alternating current of 230 V, the control information is modulated as signals in the signal lines 20a and 20b with lower voltage amplitudes, for example up to 20 or 30 V. In the normal case, that is when the lamp 10 or, where appropriate, the apparatus 15 is normally connected through the second connection 18 to the signal lines 20a and 20b, only the lower voltage transferring the control information is applied to the connection points 24a and 24b. Also at the connection points 22a and 22b only the lower voltage is present, correspondingly. When due to a defective assembly, with respect to its possible creation, some observations are made in the following text, it happens that at the connection points 24a and 24b a higher voltage is present, for example that operating voltage of a level of for example 230 V , transferred from the voltage supply lines 19a and 19b, or in case of some defective connection in the two phase conductors, in the occurrence of a voltage in the order of size of 400 V, it can occur that in normal case there is a current flow between the connection points 22a and 22b to reach the blocking Varistor 26, in order to create a conductive state, since a Varistor 26 has the peculiarity that below a limit voltage does not conduct the current and above a limit voltage is effectively driving a current. When the critical tension is chosen for example from 60 V in such a degree that the voltage margin for transferring the command information is below the critical voltage and the voltage area traditionally serving for the voltage supply of the lamp 10 is located above the critical voltage, then, in case of a faulty connection, the Varistor 26 becomes conductive so that a large current flows through it. This large current flows to it also through the fuse 26 and therefore shoots at it. Advantageously, the fuse 25 is configured as a melting fuse having metal wires mounted in a quartz glass tube filled with sand, which in case of exceeding a limit current melts and thus, after melting, separates electrically the connection points 24b and 22b in a secure manner, that is to say a spark gap test and permanently. When a faulty connection of the connection points 24a and 24b occurs in the fuse 25, the electronic system 27 of the operating device 15 is protected, which in FIG. 4 has only been incompletely indicated, as well as the following lighting elements placed at a later point, which are located behind the connection points 22a and 22b, to achieve a harmful influence caused by the excess voltage. After firing of the fuse 25 and after correcting the connection of the signal lines 20a, 20b or respectively of the voltage supply lines 19a, 19b, it is sufficient to change the fuse 25 for a new fuse, without it being necessary to change all the operative device 15 or certain parts of the electronic system 27.

The Varistor 26 can also remain inside the connection system 21. Instead of a traditional fusing fuse, which is often used in electrical appliances, and which are held, for example, with metal springs, in such a way that it can be detached by means of manual intervention, a switchable fuse, not shown here, can also be used. This fuse can be structured with manual return so that after the fuse 25 is released and the connection lines are corrected, a user can return a switch. As an alternative, the fuse can also be configured in an automatically returnable manner to return, for example, after a certain time, which could be 10 or 20 minutes, to its conductive condition. It is important that in case of the presence of excess voltage at the connection points 24a and 24b, trigger the chosen fuse 25 in a very accelerated manner so as to prevent any damage caused to the next electronic system. For example, a fuse of type FF315mA 700 V is considered as a fuse 25. The Varistor can be, for example, a Varistor S05K60 from Siemens. The operating device identified in FIG. 4 with 15 'can be a traditional pre-connection device of the DALÍ type, which can process the control information corresponding to the DALÍ protocol. The switching system 21 with the fuse 25 and the Varistor 26 can be preassembled, in the manner indicated, that is to say in front of the traditional DALY preappliance 15 ',' and can be connected, for example, also via plug connections or other connections. electrical communications to the input 18 'of the traditional operating device 15'. As an alternative there is also the possibility of incorporating the switch system 21 within an operative 'according to the present invention. Figure 3 indicates this and represents the traditional operating apparatus 15 with the second connection 18 together with the switching system 21, in the form of a unit. The second connection 18 of the operating device 15, according to Figures 3 and 4, corresponds at the same time also to the second connection 18 of the lamp according to the invention 10 since the operating device 15 is part of the lamp 10 or belongs to it As operational apparatus, not only a pre-connection device, electronic, but also any other device of a lamp 10, which at least carries a lighting element 13 or preferably can be manipulated according to the same. The fuse 25 and / or the switching system 21 can be mounted separately from an operating device 15 in a lamp 10 and they can for example also form some separate module. As an alternative, and on the other hand, a direct application of the fuse 15 or the switching system 21 could also be done inside the camera or next to the camera, of the operating device 15 or inside the camera or next to the camera of the lamp itself 10. In the same way, the fuse 25 and / or the switching system 21 can be mounted inside a current rail adapter or next to said adapter, which will be described later. For clarity, reference is no longer made to the operating principle of an operating device 15 and in Figure 4 the structuring of the traditional operating device 15 'has been illustrated in a very schematic and incomplete manner, as regards the electronic system and switching. It is important here that the operating device 15 typically comprises a first connection 17 for the voltage supply lines, a second connection 18 for the signal lines as well as an output 16 for communication with at least one lighting element 13, in which case the command information obtained through the signal lines 20a, 20b, respond to at least one illumination element, in order to turn it off or on gradually, or in its case connect it. For greater completeness the observation is made and what has not been illustrated in the figures that there is also the possibility of mounting the fuse 25 and / or the switching system 21 together with a current rail, placing them on said piece. In the following, based on FIG. 1, a traditional three-phase current rail 28, which can be used in the manner explained in this invention, will be explained as a current rail for the transfer of the operating voltage for a lamp and for the transfer of command information. The known three-phase current rail 28 consists of a basically U-shaped profile 29, made of especially aluminum, which has an input slot 30 for the head area 72 of a current rail adapter 39 (Figure 5). As regards the basic operation of a current rail 28 and the mechanical and electrical communication to a current rail adapter 39 or to a lamp in its case 10, reference is made here to the German patent application DE 103 12 012 To the applicant, whose content is incorporated in this text, that is to say within the present patent application, also for the purpose of making reference to the individual characteristics. On the side cheeks of the profile 28 are. placed four conductor rails 31, 32, 33 and 34, electrically insulated between them. The current lane 28 according to the current state of the art has a zero conductor and a three-phase conductor. With a conventional current rail adapter, for example according to German specification DE 103 12 012 Al, a user can choose which three-phase conductor the lamp in question can be connected to. In this way you can establish and join three groups of lamps to a current lane, to achieve a command by groups, in a traditional way. In accordance with the present invention, the traditional three-phase current rail can be switched in such a way that two of the four conductors, for example the conductors 33 and 34, will be switched as a signal line, through which the information can be transferred. control to the lamp 10. The other two conductors 31 and 32 are already used for the lamp, as voltage supply lines, and are commutated as a phase conductor and as a zero conductor. While the voltage supply lines 31 and 32 correspondingly correspond to the voltage supply lines 19a and 19b of Figure 3, transfer a high operating voltage for example of 230 V, it is transferred through the conductors 33 and 34 , which correspond to the signal lines 20a and 20b of Figure 3, only those control information with a voltage lower than for example 25 V. The switching, according to the present invention, of the known current rail provides on the one hand that the signal lines 33 and 34 of the current rail 28 are connected to a control (not shown) of a network of the lamps, in which case the control not shown is coupling the control information to the signal lines 33 and 34. In case If a bidirectional transfer of the control information is provided, the information of the signal line 33, 34 can also be decoupled if necessary. The switching system according to the invention of known current rail 28 further provides that the lamp 10 to be connected to the current rail 28 and / or an operating device 15 associated with the lamp and / or a current rail adapter 39 for joining the lamp to the current rail 28, have a second connection 18 or corresponding connection points 24a, 24b, which can be connected to the conductors 33, 34 of the current rail 28, in which case through this connection 18 or through these points connection 24a, 24b is transferred the control information. Figure 2 shows only in schematic form a marker element 35 in the manner of a so-called "clip" that is a clip having a coating plate 37 and two spring legs 36a and 37b. The marker element 35 can be introduced into the input device according to the arrow E inside the mouth of the current rail 28 to be secured there by the clip and thus when the marker element 35 is inserted the two free ends of the legs can be moved. of spring 36a, 36b, in interrelation, and then, after reaching a locking position immobilized by some detent, they can then be slightly enlarged so that a secure retention of the marker element 35 in the current rail 28 is achieved. The cover plate 37 carries on its underside a signal area 38, which can be labeled and which may contain, for example, an indication that the current rail 28 is switched in a certain condition. Preferably, the marking element 35 indicates that the traditional current rail 28, due to the switching system according to the invention, is in a state in which the conductors 33 and 34 are mounted as signal lines. By virtue of the marking element 35, the switching state of the current rail 28 is pointed out to the user, all in a simple way, while thanks to the configuration that can be clipped or clipped on the marker element 35, any indication possibility is available. simple. In this way, a user can obtain through the marker element 35 information to know whether or not he can use a lamp equipped for example with a DALÍ pre-connection device, inside this current lane. Next, the current rail adapter according to the invention is described, with reference to Figures 5 to 13: Figure 5 shows the current rail adapter according to the invention which is identified in its entirety with the number 39, in a perspective view. The two halves of the chamber 40a and 40b are open. From its basic structure, the camera basically corresponds to the camera of the current rail adapter according to the German report DE 103 12 012 Al, the content of which is incorporated herein to avoid repetitions and in order to make reference to various characteristics . As in the case of the known current rail adapter, two switching arrows 41 and 42 are rotatably arranged in one of the two chamber halves, ie in that left chamber half with respect to Figure 5, number 40a, two switching arrows 41 and 42, that can rotate about their corresponding longitudinal axis that has been identified in Figure 6 and that are designated there with the numbers 43 and 44. The first switch arrow 41 can be operated by a manual intervention in the actuator plate 70 and the second switch arrow 42 manipulating an edge 71 provided with a knurled contour, and in an enlarged manner, all in a form without problems. To assemble the adapter of the current rail 39, the two chamber halves 40a and 40b are turned around a hinge axis, to be locked with one another by means of a clip or clip. The head area of the current rail adapter 39 generally identified in Figure 5 with the number 72 is inserted into the mouth 30 of the current rail 28 according to Figure 1, in order to achieve its assembly in the current rail 28. .

In the first introduced condition, the first switching arrow 41 can be rotated by 90 ° and therefore the contact languages that will be described later, 73a and 73b, the retention tongues 75a and 75b as well as a coding language optionally provided 66 come out of the grooves made in the chamber halves 40a, 40b, to be able to enter the corresponding notches made in the current rail. Then the second switching arrow 42 can also rotate at 90 ° whereby the corresponding contact tongues 73c and 73d leave the corresponding grooves or openings in the box in order to come into contact with the conductors 33 and 34. from a rotation of the first switching arrow 41 a mechanical and electrical contacting occurs at the same time. By means of rotation of the second switching arrow 42, an electrical contact takes place. The two switching arrows 41, 42, as also occurs in the adapter of the known current rail, can be locked between them through a blocking device so that the second switching arrow 42 can be turned and then enter its contact state when the The first switching arrow 41 is already in a communication condition. Such an arrangement may remain under certain circumstances in the current rail adapter according to the present invention.

Figure 7 indicates in an exploded view the condition in which the second switch arrow 42 carries two contact elements 48a and 48b, which can be inserted inside the hollow switch arrow 42, moving in the input direction X. The switch arrow 42 is illustrated in a longitudinal section in Figure 11 and comprises a head area 51, an axial section 50 and a base foot section 52, which is clearly widened in comparison with the head section 51. The entire switch shaft 42 has a hollow condition and comprises two chambers 54a and 54b which are separated therebetween by a partition wall 53. This partition wall 53 and the switch shaft 42 consist of an electrically insulating material, preferably plastic, and are manufactured as an injection molded part. The foot area 52 has a blade 55 carrying two interruptions 56a and 56b, so that the entire switch shaft 42 carries a continuous opening in its axial length. A contact element 48 to be introduced in a second switch shaft 42, is illustrated in Figure 8, in cross section. It comprises a section 58 for constituting the contact language, which communicates with the corresponding conductor lane (for example the conductor 33 according to Figure 1), present in the current lane 28, and which is curved rectangularly fundamentally from a central area 59. A terminal section 60 of the contact element is curved and comprises at its free end a plug element 61 in the form of a tongue. Due to an elbow 62, that is to say an extension stage, the plug element 61 is placed in a direction slightly parallel with respect to the Terminal section 60. There is a nose or projection 64 that is located on the remote side with respect to the plug element. 61, of the central section 59. Two contact elements 48a, 48b are now inserted with respect to Figure 11 from the left, in the X input direction, into the two chambers 54a and 54b of the second switch 42, up to that the corresponding locking nose 64 is inserted behind the back 57 of the sheet 55 so as to axially fix the contact element 48, 48a, 48b on the second switching arrow 42. During this entry movement, the free end 61 is tensioned. from the Terminal section 60 to the central area 59 of the contact element 48 so that an interlocking and elastic support, with securing effect, can be reached, the contact element 48, on the switch arrow 42. When the blocking nose 64 is placed behind the sheet 55, the contact section 58 rests in the corresponding retainer tongue 49a or respectively 49b of the switching arrow 42, whereby a high degree of stability is achieved.

In the assembled state, the two contact elements 48a, 48b are separated with electrical safety by the partition wall 53. The connection conductors, not shown in FIG. 11, leading to the second connection 18 of the operating device 15 or the lamp 10, which serve for the two contact elements 48a, 48b, has in each case a flattened insertion tube at its end, which can be brought into communication, with the plug tongue 61.

A mounting of this flat insertion tube into the insertion tongue 61 can also be carried out before inserting the contact element 48 into the second switch shaft 42. In this case the contact element 48 and the insertion tube are secured. flattened with the end of the connection conductor together in the commutator arrow. In the assembled state, the insertion tongue 61 is spaced due to the elbow 64, to a slight degree of the partitioned or dividing wall 53 so that there is sufficient space for the flattened insertion tube, not shown. This also basically allows the mounting of the connection conductor with the insertion tube flattened in the contact element 48, 48a or 48b, when the contact element is already secured in the switch shaft 42. It is important that the insertion tongue 61 be extend both along the turn axis 44 of the second switch shaft 42 and also, in the assembled state of the contact element 48 towards the base of the profile 29 of the guide rail 28. A contacting of the plug tongue or insert 61 the connection conductor therefore occurs from above, with reference to Figure 8. This makes possible, as only in general form indicates Figure 5, a power supply of the two corresponding connection conductors 69c and 69d from above, up to of the commutator arrow 42. This, in general terms, results in a form of construction, with much space saving, of the current rail adapter 39, which is why it refers to its external appearance in no way should be distinguished from the current rail adapter according to the current state of the art. The observation is made that, as is particularly apparent from Figure 7, a covering element 63 is mounted, which. it closes the base or foot area 52 of the second switch arrow 42 and therefore also completely covers the contact elements 48a and 48b. Next and referring to the Figures 6 and 13, the first switching arrow 41 is described.

Figure 6 shows that the contact elements 45a and 45b basically have a rectangular shape and that in their lower free end each have an insertion element 47a and 47b, respectively, in the manner of a plug tongue. The plug tongue serves to establish communication with an opposite plug element located at one end of the connecting conductor 69a, 69b, in the manner of a flattened insertion tube. At the opposite end of the contact element 45a, 45b, there is a contact tongue 73a, 73b, which of new accounts serves to establish communication with the conductor rails (for example the conductors 32 and 31 according to Figure 1) of the rail Current 28. The contact element 45a or 45b, respectively corresponds almost completely to that of Figures 9 to 12 according to the contact element described in the German report DE 103 12 012 Al. Also the clamping of such contact element 45a and 45b have been described in this patent application, so reference is made to said document to avoid repetitions. A particularity of the arrangement is shown in Figure 5, from which it can also be concluded that through the first switching arrow 41 the two connection connectors 69c and 69d are passed for the second switching arrow 42. It is also possible to pass a ground conductor not shown in Figure 5 as another connection conductor through the commutator arrow, as shown for example in Figure 2 of the German report DE 103 12 012 Al. As a consequence, the first switching arrow 41 of a first passage channel 68a and a second passage channel 68b are provided, which serve at least for two connection cables 69c and 69d. The connection conductors 69a and 69b associated with the contact elements 45a and 45b leave the base area 52 of the first switching arrow 41, commonly with the connection conductors 69c and 69d, so that the adapter of the current rail 39 has a common output 74 for the totality of the four connection conductors or respectively under consideration of a ground conductor, a common output for five connection conductors. This common output facilitates the communication of the connection lines with the lamp that must be connected to the adapter of the current rail. As indicated in Figure 13 and Figure 7, a dividing wall 46 can be placed inside the first hollow switch arrow 41. But it is also possible to dispense with it under certain circumstances, ie when they are sufficiently isolated connecting conductors 69c and 69d and have, for example, double insulation. The first switching arrow 41 is otherwise distinguished from the second arrow 42 by the retaining tabs 65a, 65b and by a coding tongue 66. In general, the first switching arrow 41 has a structure corresponding basically completely to the construction of a switching arrow illustrated in Figure 8 of German DE 103 12 012 A1. It is possible that an additional coding language 66 has already been mounted, but said part is not illustrated here in greater detail, as regards its functioning,. The observation is made that the contact elements 45a and 45b are inserted in the corresponding chambers 67a and 67b, to enter the first switching arrow 41 to be secured axially with the so-called blocking noses or projections 75 (Figure 6), which are placed behind the corresponding wall areas 76 of the first switching arrow 41. The current rail adapter according to the invention 39 has on the first switching arrow 41 the contact elements 45a and 45b, which can be brought into contact with the zero conductor or 31 of the current lane. 28 and with the phase conductor 32 of the current rail. The second switching arrow 42 has two contact elements 48a and 48b, which can be brought into contact with the signal lines 33, 34 of the current rail 28. In this way a lamp 10 according to FIG. only current rail adapter 39, to be connected to the current rail 28. The contact tongue 73 therefore corresponds, for example, to a contact language of the zero conductor, the contact language 73b corresponds to a contact language of phase conductor and the contact languages 73c and 73d correspond to the contact languages of the signal line.
