Description

The invention further relates to a lamp with a socket and a holder for a lamp according to the preamble of claim 1. The invention also relates to a lamp with a holding part and a socket according to the preamble of claim 2. Finally, the invention relates to a first method for mechanical fixing of Finally, the invention relates to a second method for mechanically fixing a lamp in a luminaire by intermeshing the lamp base and the lamp socket according to the preamble of claim 20.

From the prior art double ended lamps, in particular fluorescent lamps are well known. For example, on the DE 10 2007 054 930 A1 referred to the applicant. Such double capped, tubular fluorescent lamps have at their respective ends socket contacts in the form of contact pins, which are each inserted into a socket. These are usually sockets with a rotor, in which the contact pins are fed via a slot in the socket housing the rotor and moved by subsequent rotation of the lamp with the rotor driving in both a contact position, in which the socket contacts with the contact pins of Lamp enter an electrical connection, as well as the mechanical support is achieved. Such lamps are used in lights, by means of which elongated rooflights in offices, industry and commercial buildings and in some cases in private households are realized. Two-sided fluorescent lamps have prevailed in many areas due to their design possibilities, also because they are more conventional than other conventional ones Bulbs with the same electrical power have a higher light output.

In their handling, however, they have some disadvantages when inserting and disassembling the lamp, since the socket pins of both lamp ends are usually not synchronously used in the versions, which is due on the one hand in the handling by the user, and its cause is that the insertion of the socket contact pins into the narrow insertion openings of the sockets is imprecise. The longer the fluorescent lamp itself is the more uncomfortable is the handling. The user must be very careful not to destroy the lamp when inserting or accidentally dropping due to the low intrinsic stability of the fluorescent lamps.

Then comparatively elongated single-ended fluorescent lamps are known from the prior art, which are used in luminaires with only one socket. In order to reduce the mechanical stress on the socket and to ensure correct alignment of the lamp in the lamp, these lamps can be provided with an additional holder for the fluorescent lamp, which is usually a locking element. This partially surrounds the fluorescent lamp, which itself has no additional holding means. Reference is made to Articles 26.746.1001 and 26.726-013 shown in Catalog 2008-2011 on pages [03] 52 to [03] 54 of the Applicant. In such systems, the assembly of the fluorescent lamp by inserting it sideways regularly good. In general, not inconsiderable forces must be applied to insert the lamp in the socket. However, since the lamp socket mount provides a final assembly travel end stop, the user has the assurance that he will not lose the lamp by mistake. The same applies to the engagement of the lamp in the light-side holding element.

Again, the holding element offers a Montageendanschlag for the fixing movement. Much more uncomfortable for the user is the disassembly of such a fluorescent lamp, since here with relatively high effort the sensitive fluorescent lamp from the latching retaining element of the lamp and then has to be pulled out of the lamp socket. The usually sudden overcoming of the holding forces of the holding element and the socket results in a sudden movement of the lamp in the dismounting direction, with the risk that the lamp is accidentally dropped or abuts against the lamp housing.

On one side electrically contacted, but two-sided mechanically held lamps have become known inter alia from the search results for the original application. The determined there US 2012/0307524 A1 shows such a lamp using LEDs, in which an axial movement space is necessary for the arrangement of the lamp between the holders. this is ensured by axila movably mounted and acted upon by a restoring force retaining elements.

US 2012/0049739 A1 shows two-sided held LED lamps, which can be fixed to each other by means of mechanical connectors. For this purpose, the connectors have corresponding threaded portions, which engage in one another by means of a rotation. The connectors also enable electrical contacting of two lamps arranged one against the other. A partially gripping holder fixes the lamp to a luminaire purely mechanically.

Also will open US 2013/0002164 A1 referenced, in which arranged on end caps mounting bracket engage in corresponding openings on the luminaire side. After an axial displacement, the angles engage behind light projections, so that the lamp mechanically is secured. At the same time sort the axial displacement for that dips the electrically contacting end of the lamp in a receiving portion of the lamp and is also mechanically maintained.

A double ended LED lamp is in DE 20 2013 001 101 U1 shown

In addition, old lamp shapes have the disadvantage that when a plurality of lamps are arranged side by side, those portions do not generate any light which occupies the lamp base and the casings. This results in light bands, which are formed from several lamps, shaded areas.

Finally, LED lamps are known as a substitute for such fluorescent lamps from the printed documentation not assignable prior art. However, these use the known socket and socket systems. In order to be able to serve as a retrofit or replacement lamp for existing luminaires, such LED lamps are also modeled on the classic fluorescent lamps in their design.

In particular, LED lamps in the design of a classic, tubular fluorescent lamp generally have an aluminum body extending over the entire length of the lamp for cooling the LEDs. Compared to the glass tube of a fluorescent lamp, it comes here to considerable length expansions, due to the heating during operation, which in turn can cause tension of the built-in lamp or even a deformation of the complete lamp. In addition, this leads to contacting problems when the base contacts dissolve by reducing the length of the lamp when cooling the socket contacts.

The object of the invention is to improve the mounting of a lamp, in particular an LED lamp in a lamp, in particular in such a lamp, which can serve the creation of improved elongated light bands.

The object is initially achieved by a luminaire with the features of claim 1, in particular with its characterizing features.

The main advantage of the invention is the fact that the lamp forms a holder which serves only the mechanical fixing of the lamp and not in addition to an electrical contact and is also adapted to receive a merely mechanical fixing of the lamp serving holding part. The fact that both light as well as lamp side components are provided, which in cooperation with each other only serve the mechanical determination of the lamp in the lamp, it is possible to provide these components to a maximum of ease of use and a minimal design and favorable positioning the lamp and the lamp to optimize.

This holder for a lamp on a lamp component comprises a substantially cup-shaped base body, on the bottom of two opposing end walls are arranged, which hold between them two likewise opposite side walls, wherein the front and side walls enclose a receiving space which is accessible via an opening , which divides into a slot portion and a rearward in the insertion direction holding portion. The main advantage of the holder is the fact that it does not require detent or clamping means in this simple embodiment, and thus a substantially force-free mounting of the lamp in the holder is possible.

Part of the lamp is also a socket with a recess for receiving a mounting dome of a base in which a spring-loaded pressure plate is arranged and with a recess arranged in the retaining pin, which is articulated spring return elastic and optionally with socket contacts for electrical connection to contacts of a lamp cap, if the holder is designed as a lamp holder.

The main advantage of this version can be seen in their interaction with the aforementioned base, which realize a so-called push-in - pushout principle for anchoring the base in the socket. This is characterized by the fact that a depression of the socket into the socket initially leads to a mechanical anchoring and electrical contact and leads a renewed impressions of the lamp cap in the socket to a detachment of the socket from the socket. The central element here is the socket-side retaining pin, which is first moved via the spring return elastic deflection in cooperation with the guide surfaces of the lamp cap in a locking position and then in a release position. The spring-loaded pressure plate ensures that the retaining pin securely remains in the socket-side locking portion and after renewed pressing of the socket in the socket is moved out of the socket socket.

A preferred embodiment is characterized in that the holding portion is formed by two opposing, oriented in the insertion direction webs, which narrow the opening in the region of the holding portion groove-forming.

It is envisaged that a holding part is only used for the mechanical fixing of the lamp in the lamp and is formed contact-free with respect to electrical contacts, wherein the holding part in the light side, only the mechanical fixing of the lamp serving bracket is used. In this case, the webs of the holder are oriented at ceiling mounting approximately transverse to the direction of gravity, so that the holding part of the lamp can rest on them. In this specific embodiment, it is clear that a latching or clamping down in the light-side bracket is not necessary and therefore a simple installation and above all disassembly is possible.

Furthermore, it is provided that in the receiving space at least one guide surface is arranged, which controls the insertion movement of a lamp component to be used. The control surfaces serve to further improve the operation of inserting the holding member into the holder. The guide surfaces ensure that the insertion into the holder is a flowing movement and tilting of the holding part is avoided when mounting in the holder. In particular, the guide surfaces convert the insertion movement into the insertion section into an insertion movement into the retaining section.

Specifically, it is provided that the guide surface of the front wall lying in the direction of insertion springs and falls to the ground, in particular, when the guide surface extends parallel to the ground from the front end located in the insertion direction up to the rear wall in the insertion direction.

It is further provided that the retaining space formed between the webs and the bottom of the holding portion is dimensioned such that a holding part of a lamp to be inserted is substantially free of play durable.

Furthermore, it is provided that the holding space is bounded by the webs and the bottom guide surface.

Finally, it is provided for a simple mounting of the holder in the luminaire part, that the front and / or side walls outside locking means have to anchor the holder in a section of the lamp component can. However, it is alternatively also conceivable that the holding part is an integral part of the lamp component.

Before the above-mentioned prior art and the object of the invention, there is a further solution in a lamp with the features of claim 9, in particular with its characterizing features.

Analogous to the advantages of the lamp, the advantages of the lamp can be seen. Again, the lamp-side holding part in its combined interaction with the light-side holder offers the possibility to align the holding part only on a good manageable mechanical connection with the light and no compromise in terms of electrical contact must be received.

The holding part of the lamp has a limited by a holding part bottom and holding part side walls receiving space for lamp components, wherein one of the holding part side walls on the outside has an anchor portion for mechanically fixing the lamp to a lamp.

The main advantage of the decided trained holding part is the fact that this can be performed optimized only on the holding function. Unlike in the prior art, it is not necessary to meet other requirements, such as a good electrical contact. Compared to the other cited prior art, the dedicated trained holding part on the side of the lamp has the advantage that it relative to the lamp envelope is less sensitive and is well preserved by the user during assembly and disassembly of the lamp.

In a specific embodiment, it is provided that the anchor portion of the holding part has an anchor head which is fixed by means of an anchor pin on the holding part side wall, in particular if the anchor pin is narrower than the anchor head and the anchor portion is configured as a whole in approximately T-shaped.

This design of the anchor portion allows an ideal interaction with the above-described holder by the particular T-shaped designed anchor portion is mounted in the holding portion of the holder on the webs, whereas the anchor pin exits between the webs and so holds the lamp.

To operate a lamp in a lamp, in addition to the interaction of the holder and holding part, so the mechanical connection of the lamp in the lamp and an electrical connection between the lamp and lamp is required. Therefore, the invention is also directed to the lamp base of the lamp according to claim 9, with base contacts for electrically contacting socket contacts.

This base is provided with a mounting dome suitable for insertion into a second embodiment of a lamp socket having a spring return resiliently hinged retaining pin for mechanically anchoring the retaining member, the mounting dome having guide surfaces forming a trajectory along which the retaining pin is guidable Movement path is adapted to deflect in a relative movement of the base and socket, the retaining pin by means of a Auslenkabschnitts under construction of a spring tension from a rest position in a first direction, by means of a return section with partial reduction of the spring tension in Due to its rest position, while maintaining a residual spring tension to hold in a locking portion which is part of the return section.

Such a lamp cap is part of a so-called push-in push-out arrangement in which the lamp cap is held by pressing into the socket in an anchoring position and is guided by re-impressions in the socket in a release or disassembly position. When the first depression of the socket into the socket, the holding pin arranged in the socket is moved into the locking section of the socket and thus holds the socket in an assembly position. In this there is a mechanical anchoring of the base in the socket and thus the lamp in the lamp instead. An electrical connection between the socket and socket-side contacts is realized in this way.

It is envisaged that the anchor head is formed like a roller at least at its end portions. In particular, in connection with the guide surfaces on the side of the above-described holder allow the roller-like shaped end portions to ensure a comfortable, sliding assembly.

In a corresponding development of the socket according to the invention it is provided that the movement path is suitable for further relative movement of socket and socket to release the retaining pin from the locking section, to reduce the spring back tension from the return section into an Ausführabschnitt the trajectory.

The main advantage is now to be seen in the fact that a renewed pressing of the socket in the socket releases the retaining pin from the locking portion and transferred to the Ausführabschnitt, so that the socket can be removed from the socket. In this case, when removing the socket from the socket in this embodiment, no significant effort is needed. Rather, the base slides out of the socket almost independently. At most, a certain frictional engagement may hold the base taking into account the weight of the lamp connected to the socket in the socket.

In order to prevent accidental slipping out of the base of the socket and to hold the lamp at a deliberate or accidental release of the retaining pin from the locking portion in the socket, it is provided that the Ausführabschnitt is adapted to the retaining pin with rebuilding a spring tension in to deflect a second direction opposite to the first direction of deflection.

The main advantage here is to be seen in the fact that the retaining pin can slip out only under construction of a renewed spring tension through the Ausführabschnitt. This spring tension is dimensioned so that it readily prevents slipping out of the retaining pin from the locking portion solely due to the weight of the lamp.

Finally, it is provided that the guide surfaces belong to a guide groove incorporated in a side wall of the mounting dome.

It is further provided that the guide groove springs from an inlet opening, through which the retaining pin is inserted into the groove and terminates in an outlet opening, through which the retaining pin can be removed.

For a cooperation with the above-described socket a suitably designed version is required.

As can be imagined, one can form the holder in its objective embodiment according to the holding part and then form the holding part in its objective embodiment corresponding to the holder. In this case, the holding part would thus be light side, the holder, however, mounted on the lamp side. Since only the arrangement of the holder and holding part to lamp or lamp replaced, but not the function is changed, such training is to be regarded as equivalent. In the same way, this applies to the designated as socket and socket components.

The invention further provides a method for mechanically fixing a lamp in a luminaire according to claim 17. It is characterized in that the anchor portion of the holding part in a first, linearly directed movement through the opening into the receiving space of the holder and there in the insertion section is moved and is inserted in a second, also linearly directed movement in the holding portion of the receiving space of the holder.

Provided in a development that the anchor head is inserted into the insertion portion and the holding portion is inserted, the anchor pin is pushed between the groove forming webs.

Finally, it is provided that the guide surface converts the first linearly directed movement into the second linearly directed movement.

Furthermore, a component of the invention is a method for mechanically fixing one and one luminaire according to claim 20. This method is characterized in that the mounting dome is inserted into the recess of the socket by means of an assembly movement in a mounting direction, wherein the retaining pin acts on at least one guide surface of the deflection section meets and the pressure plate the Version is shifted by building a spring tension by a first distance.

This is further developed by the retaining pin over the assembly movement away along the deflection portion of the movement path slides and at the end of the assembly movement in the return section dips until it is anchored in the locking portion.

Then it is provided that a disassembly movement is performed to release the locked retaining pin, which is initially the same direction with the assembly movement.

Finally, the method is developed by moving the retaining pin in carrying out the disassembly movement in the Ausführabschnitt.

It is also provided that, in continuation of the disassembly, reversing the direction of movement of the retaining pin is guided under renewed elastic spring return elastic deflection through the Ausführabschnitt the trajectory.

And finally, it is provided that the continued disassembly movement is induced with movement direction against the mounting movement of the spring-loaded pressure plate of the socket.

In the figures, a luminaire according to the invention is provided overall with the reference numeral 10. It is in perspective view in FIG. 1 shown.

The lamp 10 receives at least one, in the present embodiment, however, a plurality of elongated, assembled into a line-like light band lamps 11. For mechanical anchoring of the lamp 11, the lamp 10 has a holder 12 which cooperates with a holding part 13 of the lamp 11. The holder 12 and the holding part 13 are used exclusively for mechanical fixing of the lamp 11 to the lamp 10, whereas a light-side socket 14 and a lamp-side base 15 of the mechanical anchoring of the lamp 11 in the lamp 10 and the electrical connection are used. The base 15 is arranged at a first end of the lamp 11, the holding part 13 at a second end of the lamp 11 so that the lamp type according to the invention is a double-sided lamp type.

The lamp 10 is kept fairly simple in the embodiment. This is a carrier in H-shape with two spaced apart vertical legs 16 and a horizontal leg connecting them 17. The lamp 10 forms in this way a viewer facing receiving space 18 for the lamp 11 and a supply space 19, the viewer is facing away and which receives the socket 14, the holder 12 fasteners for the arrangement of the lamp to building parts and, for example, live cables and control cables.

The lamp itself is designed as an LED lamp, which not only has advantageous properties in terms of energy consumption, but in which the light direction can be influenced by the arrangement of the individual LEDs. In this way, the shaded by the base 15 and the holding part 13 gap between two consecutively arranged lamps 11 are illuminated to the viewer, so that a light band with continuous uniform light emission arises.

The holder 12 is alone in the FIGS. 3 to 5 shown. In the bottom view ( FIG. 3 ) is first apparent that the holder 12 forms a substantially cup-shaped base body, the bottom 20 holds two opposite end walls 21 and 22. Between the end walls 21 and 22, two side walls 23 and 24 are held. The bottom 20, the end walls 21 and 22 and the Side walls 23 and 24 form a receiving space 25 which is accessible via an opening 26. The opening 26 is divided in the direction of a direction of insertion X in a front insertion portion 27 and a rear insertion X in the holding portion 28. The holding portion 28 is defined by two spaced opposite, in the insertion direction X-oriented webs 29, the opening 26 in Narrow the region of the holding portion 28 groove-forming, so that the holding portion 28 is formed as a kind of undercut retaining groove. The holding portion 28 is formed in the insertion direction X so long that at least the production-related length tolerances of the lamps 11 are compensated. However, it is preferable to also provide a space for compensating the thermal expansion of the lamp 11, as will be described later.

In the receiving space 25 of the holder 12 guide surfaces 30 are arranged, which serve to control the insertion movement in the insertion direction X of a holding part 13. The guide surfaces 30 originate from the first end wall 21, close to the opening 26, drop toward the bottom 20 and run parallel to the ground in the region of the holding section 28. Between the webs 29 and the bottom 20 so a holding space 31 of the holding portion 28 is formed.

As seen from the perspective view of the holder 12 in FIG. 4 shows, the side walls 23 and 24 are provided with locking means 32 which serve to anchor the holding part 13 in the cutout of a lamp component. A circumferential collar 33 on the edge of the holder 12 facing the lamp 11 serves as an abutment, which prevents slippage of the holder 12 by the aforementioned cutout of a lamp component. However, it is also conceivable that the holder is integrally integral part of a lamp component and not, as proposed here, is made as a separate component for equipping a lamp.

The sectional view of the holder 12 along the section line AA in FIG. 3 illustrates on the one hand in particular the presence of the holding space 31 in the holding portion 28 and the course of the guide surface 30. This falls - starting from its opening near origin in the first end wall 21 - along a circular path section to about the level of the bottom 20 from. Alternatively, however, the sloping course may take another form. This corresponds preferably with the part to be used 13th

With the holder 12 corresponds to the mechanical fixing of the lamp 11 in the lamp 10, a holding part 13, which in a perspective view in FIG. 6 is shown.

The holding part 13 of the invention sits on the end of the lamp 11 and thus forms part of the lamp housing. For this purpose, a holding part bottom 34 holding part side walls 35, which has a in FIG. 6 away from the viewer away receiving space for lamp components form. The holding member 13 is therefore formed as a cap, which is attachable to the end of the lamp 11 and, for example, holding elements for a cover glass 43 and a board 44 which is provided with LEDs 45, formed. The holding part 13 is provided on an armature side wall 35 facing the lamp with an anchor portion 36 for mechanically fixing the lamp 11 to the lamp 10. This anchor portion 36 forms an anchor pin 37, which springs from the holding part side wall 35 and carries an anchor head 38 at its free end. The anchor portion 36 is configured so far in an approximately T-shaped. The end portions 39 of the anchor head 38 are shaped roughly like a roll.

In FIG. 6a is now an alternative embodiment of the holder 13 according to FIG. 5 shown. This differs from the holder 13 according to FIG. 5 in particular in that in the receiving space 25, a spring element 40 is arranged, the spring arm 41 is arranged in the holding space 31. The spring arm 41 is displaced upon insertion of the holding part 13 in the holder 12 from the anchor portion 36 in the insertion direction X from its rest position out. As an alternative to the leaf spring element selected here are other spring elements, such. B. coil springs conceivable that are displaced from a rest position out in the insertion direction X, when the holding part 13 is inserted into the holder 12.

The holding part 13 and the holder 12 act together as a system for mechanically fixing a lamp 11 in a lamp 12. The nature of this interaction and the operation of inserting the holding member 13 in the holder 12 will now be made recourse to the illustration of FIG. 7 explained in more detail.

FIG. 7 is a partial sectional view of the lamp 10 according to FIG. 1 with a view of the arrangement region of the holder 12 and holding part 13. From the lamp 10 itself, only the horizontal leg 17 of the H-like trained lighting profile is shown. In a recess 42 of the horizontal leg 17, the holder 12 is locked.

An end portion of the lamp 11 in sectional view is also in FIG. 7 seen. From this it is apparent that the holding part 13 with its holding part bottom 34 and its holding part walls 35 forms a receiving space for lamp components. Within this unspecified receiving space end portions of the lamp cover 43 and a circuit board 44 are held, wherein the board 44 is provided with a series of LEDs 45.

The lamp 10 facing the holding part side wall 35 carries - as already mentioned - the armature portion 36 of the below the holder 12 in front of the opening 26 in the region of the insertion portion 27 to arrange is. The anchor head 38 is now inserted in the insertion direction Y through the opening 26 in the receiving space 25 of the holding part and then slides on the guide surfaces 30 in the insertion direction X from to immerse in the holding space 31 of the holder 12.

The now engaging in the area of the undercut anchor head 38 has the connection between the webs 29 out of the holder 12 further armature pin 37 connection to the lamp 11 and holds it against the direction of gravity of the lamp 10. The advantageous roller-like configuration of the end portions 39 of the anchor head 38 allowed pivoting the lamp 11, which in this state is only one-sided mechanically held on the lamp 10, around the anchor head 38 as the center of the pivoting movement. This is advantageous with regard to the connection of socket 15 and socket 14, which will be described later.

From the illustrated interaction of holder 12 and holding member 13 will be immediately apparent to anyone that the structural features of the holder 12 may be formed on the side of the lamp 11 in the sense of a holding part, if the structural features of the holding part 13, in particular the formation of the anchor portion 36 are formed on the side of the lamp 10. In this respect, such an exchange, i. to form the holding part 13 in terms of features such as the holder 12 and at the same time form the holder 12 as the retaining part 13 in terms of features, to be regarded as equivalent.

The FIG. 9 is one of the FIG. 7 corresponding representation, but here a holder 12 was used on the light side, the modified embodiment of the FIG. 6A equivalent. It was therefore supplemented by a spring element with spring arm 41. Again, the assembly process of the holding part 13 in the holder 12 initially according to the description FIG. 7 run.

However, in order to complete the assembly process, in which the lamp must be moved to an end stop in the insertion direction X, the spring arm 41 is displaced by the anchor head 38 from its rest position and builds against the insertion movement X directed spring force. This has the consequence that when dismantling the lamp 11, including a release of the socket and socket is necessary (see below) by the spring arm 41, an ejection movement is induced. In this case, the spring forces urge anchor head 38 in a direction opposite to the insertion movement X direction until the spring arm 41 has reached its rest position. It should be noted, however, that in a particularly preferred embodiment, the anchor head 38 is moved by the spring arm 41 during disassembly of the lamp 11 in the direction of the insertion portion 27 of the holder 12, but does not get into this. Instead, it remains in the holding portion 28, so that the transition into the insertion portion 27 and thus a gravity-induced sliding out of the anchor portion 36 from the holder 12 does not take place.

In this context is on FIG. 8 Reference is made, which shows a simplified partial view of a side view of the lamp 10 in the region of two lamps 11 arranged one behind the other. In this illustration, the vertical leg 16 of the lamp 10 have been omitted. The anchor portion 36 together with the holding part 13 has been shown by dashed lines in two different positions. In a spaced-apart arrangement of the lamps 11, the anchor head 38 has approximately in the FIGS. 7 and 9 shown position in the holding portion 28 of the holder 12. By continuing the insertion movement X reach the lamps 11 in the immediate vicinity.

The lamp 11, of which the socket 15 provided with the end portion is shown, wherein the base 15 in the socket 14th is anchored, is already fully assembled so that it is forced in terms of the above process, no movement in the X direction.

Based on Figures 10 and 10a Now another embodiment of the holder and holding part will be described. Both are provided in the present embodiment with contacts that form an electrical connection in the assembled state of the lamp 11. In that regard, the holder and the holding part of this alternative embodiment are designed as a socket 14 and socket 15 and are referred to below. However, since mechanical anchoring forms the gist of the invention, this term choice is not intended to be limiting. at FIG. 10 it is a simplified partial sectional view of the lamp 10 according to FIG. 1 showing the arrangement area of socket 14 and socket 15. FIG. 10a on the other hand shows a view in the direction of insertion X on the base 15 and the socket 14, wherein in the version 14, the in FIG. 10 shown, front in the direction of insertion X front housing wall 50 is broken away. FIG. 10b finally shows a perspective view of the lamp base 15 in the insertion direction.

The lamp base 15 initially forms, similar to the holding part 13, a pot-shaped recess for different lamp components, as is evident in particular from the sectional view of FIG FIG. 10 is apparent. Mirrored to the holding part 13 and this recess also assumes the lamp cover 43 and the board 44 in an analogous manner.

As first from the perspective view in FIG. 10b It can be seen, the lamp base 15 has a pointing in the direction of light fitting assembly 51 51, the contact recesses 52 forms, in which base contacts 53 are seated. The contact recesses 52 in In front of the insertion direction X, a fastening section 54 is located, the front side of which in the insertion direction X and facing the front housing wall 50 of the socket forms a guide groove 55 which forms guide surfaces for a retaining pin 56 of the socket 14. This guide surfaces form a trajectory along which the retaining pin 56 is feasible, as will be explained in detail later.

The front view of the lamp holder 15 in Figure 10A is particularly suitable to explain the individual sections of the guide surfaces and the guide groove 55.

The guide groove 55 springs from a socket 14 facing the inlet opening 57, which is aligned with a free end portion 58 of the retaining pin 56 and is arranged in the embodiment in a lamp longitudinal axial, directed vertically to the horizontal leg 17 level.

Starting from the inlet opening 57, the guide groove 55 initially forms the so-called deflection section 59. This is guided at an angle to the aforementioned vertical plane and merges into a wave-like return section 60. This return section also contains a locking portion 61 and merges into the Ausführabschnitt 62, which in turn opens itself in an outlet opening 63.

In the Figure 10A also shown socket 14 has a socket recess 64 which is formed substantially complementary to the mounting dome 51 of the base 15. The aforementioned holding pin 56 of the socket 14 is fixed at one end in the socket housing 65 and directed in the direction of the insertion opening 66 with its free end portion 58. Via the insertion opening 66, which faces the base 15, the mounting dome 51 can be introduced into the socket recess 64.

The retaining pin 56 is also in the aforementioned vertical plane in the embodiment shown here. For the post-described function, however, it is urgently significant that it is aligned with the inlet opening 57 of the guide groove 55. The retaining pin 56 is also formed Federrückstellelastisch and preferably consists of a spring steel wire, wherein the free end portion formed by bending in the insertion direction X a locking tab 67, as the lamp longitudinal section according to FIG. 10 shows. For a better overview, see Figure 10A in deviation from FIG. 10 not shown arranged in the socket recess 64 pressure plate 68, which can be pressure-loaded via at least one coil spring 69.

Finally, the socket 14 forms a contact space 70, in which socket contacts can be arranged, which form an electrical connection with the socket contacts 53.

Version 14 and the base 15 in their interaction form a system for mechanically fixing the lamp cap 15 in the socket 14 and thus a system for mechanically supporting the lamp 11 in the lamp 10 while ensuring a corresponding power supply and - if necessary - the electrical connection of control lines with which, for example, light color and light intensity of an LED lamp 11 can be influenced. This also implies a mounting method for inserting a lamp cap 15 in a lamp socket 14. This will now be described with reference to FIGS FIGS. 11 to 14 continue running.

The FIGS. 11a . 12a . 13a and 14a each show a side view of the lamp 10 in the arrangement region of the base 15 and socket 14 and differ only in their respective arrangement position between the lamp 11 and lamp 10. In particular, the different immersion depth of the mounting pin 51 of the base 15 in the Socket recess 64 of the socket 14 shown. The corresponding representations 11b, 12b and 12c, 13b and 13c and 14b are those which the FIG. 10a are modeled. These are therefore views of the arrangement region of the socket 14 and base 15 in the insertion direction X, wherein the front housing wall 50 of the socket 14 is broken away.

The insertion of the base 15 in the socket 14 and their interaction for the mechanical anchoring of the lamp 11 in the lamp 10 will now be shown below.

FIG. 11a shows a pre-assembly in which the base 15 is arranged with its mounting dome 51 of the socket 14 and the socket recess 64 facing. Again FIG. 11 It can be seen b, is the spring restoring elastic deflectable retaining pin 56 in its rest position, its locking tab 67 is the inlet opening 57 of the guide groove 55 facing.

In FIG. 12 is now shown that the mounting dome 51 has been moved through the insertion opening 66 of the socket 14 a first piece into the socket recess 64. The locking tab 67 of the retaining pin 56 dives through the inlet opening 57 of the guide groove 55 in the same (see FIG. 12b ). This is done by the mounting dome 51 and the base 15 is moved in the insertion direction Z. In a continuation of the movement, the locking tab 67 slides along the deflection portion 59 of the guide groove 55, whereby the retaining pin 56 is deflected spring return resiliently from its rest position. In this case, the deflection section 59 encloses an angle with a plane directed vertically to the horizontal limb 17 and extends along the length of the lamp axis and is inclined in the insertion direction Z to this plane.

As FIG. 12c shows the locking tab 67 after completion of their movement along the deflection section 59 in the so-called return section 60 which extends approximately transversely to the aforementioned plane and allows the return of the retaining pin 56 in its rest position. About the transversely to the insertion direction Z extending guide surface portions of the guide groove 55 in the return section 60, a Bewegungsendanschlag is defined, which limits the insertion of the base 15 in the socket 14. When inserting the base 15 in the socket 14 of the assembly dome displaces the in FIG. 10 illustrated pressure plate 68 against the coil spring 69 also in the insertion direction Z, wherein the coil spring 69 a the insertion direction Z opposing spring tension builds up.

The guide groove 55 is approximately roof-shaped in the region of the return section 60, the ridge being directed into the socket recess 64. When the locking lug 67 reaches the movement end stop formed by the return section 60, the base 15 is released. Due to the roof-like design guide groove 55 in the return section 60 in cooperation with the locking tab 67 in the rest position moving spring tension, the locking tab 67 slides in the direction of ridge line, with a minimal backward displacement of the base 15 against the insertion Z caused by spring-loaded pressure plate 68. If the locking nose 67 reaches the ridge area, the return movement of the retaining pin 56 is terminated for the time being. A residual spring tension remains the retaining pin 56, however. The locking tab 67 is seated in the locking portion 61 (the ridge) of the guide groove 55 and holds the base 15 against gravity direction in the socket 14. The base 15 is mechanically anchored in the socket 14 (see FIGS. 13a and 13b ). At the same time there is an electrical connection between the socket contacts and the socket contacts 53rd

To release the base 15 from the socket 14, the base 15 is again moved in the insertion direction Z. In this case, the locking tab 67 slides out of the locking portion 61 and in the direction of rest position of the retaining pin 56 until it reaches the Ausführabschnitt 62 of the guide groove 55. The transition from the return portion 60, which contains the locking portion 61, in the Ausführabschnitt 62 is located shortly before the point at which the locking tab 67 is located in the rest position of the retaining pin 56. The Ausführabschnitt 62 itself in turn encloses an angle with the above-defined lamp longitudinal axial plane, but is directed in the insertion direction Z of this pioneering.

The transition of the locking tab 67 in the Ausführabschnitt 62 is in Fig. 13c shown. At the same time, the return section 60 in the transition area into the Ausführabschnitt 62 by the guide surfaces of the guide groove 55 in turn forms a Bewegungsendanschlag, which prevents further insertion of the base 15 in the socket 14 into it.

After releasing the base 15, this now induced by the spring force of the coil spring 69, contrary to the insertion direction z slides out of the socket recess 64 until a removal position is reached. Due to the course of the Ausführabschnittes this exit movement forces again a spring return elastic deflection of the retaining pin 56, which is arranged in its rest position in the vertical plane (see above). The movement of the base 15 against the insertion direction Z when loosening from the socket 14 must therefore take place against the spring restoring force of the retaining pin 56, the thereby generated friction on the guide surfaces of the guide groove 55 brakes the movement. In an advantageous embodiment, the spring restoring force or induced by the Ausführabschnitt 62 deflection of the retaining pin 56 is dimensioned so that a return displacement of the base 15 from the socket 14 out against the insertion Z, for example, by gravity can be done only to a certain extent, without However, additional effort by a user, this removal movement is not completed, so that the base 15 is held in the socket 14 in a removal position ( Fig. 14 ).

In this way it is prevented that in an accidental as intentional release of the base 15 from the socket 14, the lamp 11 uncontrollably leaves its mechanical anchoring and unintentional falling out of the lamp 11 from the lamp 10 is not possible. Only pulling out the base 15 from the socket 14 overcomes the frictional connection and forces the retaining pin 56 a deflection, via which it is adapted to leave the guide groove 55 via the outlet opening 63.

Finally, the assembly of the lamp 11 in the lamp 10 is now described, which uses both the method for inserting the holding part 13 in the holder 12 and the method for inserting the base 15 in the socket 14.

In this mounting method, the holding part 13 is first positioned in front of the opening 26 in the region of the insertion section 27 of the holder 12. The anchor head 38 is moved through the opening 26 in the insertion portion 27 in the insertion direction Y. The insertion direction Y is then transferred via the guide surfaces 30 in the insertion direction X. A further movement in the direction of insertion X of the anchor head 36 leads to its arrangement in the holding section 28. If present, the spring arm 41 of the einitzenden in the holding space 31 spring 40 is urged under construction of a spring tension from its rest position.

When inserting the holding member 13 in the holder 12, the lamp 11 has a lamp 10 inclined position (see Fig. 2 ), so that the Socket 15 is clearly spaced from the socket 14. Due to the possible by the shape of the end portions 39 of the anchor head 38 pivoting movement of the lamp 11, it is now possible zuzubewegen the base 14 in the insertion direction Z on the socket 14. The pivoting movement takes place around the anchor head 38, so that the insertion direction z is actually a circular movement and not a strictly linear movement. Due to the large radius, which is determined by the length of the lamp 11, the actual insertion movement Z of the mounting mandrel 51 into the socket recess 64 can be considered as a linear movement.

In continuation of the pivoting movement now passes the mounting dom 51 of the base 15 in the region of the insertion opening 66 of the socket housing 65 of the socket 14. He penetrates the insertion opening 66, wherein the locking tab 67 of the retaining pin 56 passes through the inlet opening 57 in the guide groove 55. It slides along the deflection section 59 while building up a spring tension along and is deflected spring return elastic. When the locking lug 67 arrives in the transition region from the deflection section 59 into the return section 60, the guide surfaces of the guide groove 55 form a movement end stop for a movement in the insertion direction Z.

The result of the movement of the mounting mandrel 51 into the socket recess 64 is that a pressure plate 68 which is spring-loaded in the socket recess 64 is also displaced in the insertion direction Z, building up a spring tension. When the locking tab 67 reaches the end of travel stop, the socket 15 is released by the user. The spring tension acts on the mounting mandrel 51 via the pressure plate 68 and leads to a partial rearward displacement against the insertion direction Z, wherein the retaining pin 56 moves along the guide groove in the return section 60 in the direction of its rest position. A roof-shaped portion of the return portion 60, which is the actual Locking portion 61 forms, allows movement of the locking tab 67 up to a ridge. If this is reached, the return displacement of the mounting mandrel 51 induced by the pressure plate 68 also ends out of the socket 14. The locking tab 67, which rests in the locking portion 61 of the guide groove 55, now holds the base 15 against the spring-loaded pressure plate 68 and the possibly acting gravity in the socket 14. The base 15 is mechanically anchored in this way in the socket 14.

If the lamp 11 mounted in this way and held by the base 15 and the socket 14 on the one hand and by the holder 12 and the holding part 13 on the other hand, comes another advantage of the interaction of the holder 12 and holding part 13 to wear. When the lamp 11 is mounted, the anchor head 38 is mounted at a distance from the nearby second end wall 22 located at the rear in the insertion direction. Occurs now during operation of the lamp 11, the above-mentioned thermal expansion, the anchor head 38 in the holding section 28 correspondingly wander in the direction X, so that no damage to the lamp 11 or lamp 10 occur. The holder 12 and the holding part 13 thus allow the compensation of the thermal expansion of the lamp eleventh

To remove the lamp 11 from the lamp 10, the base 15 is now first again moved into the socket recess 64 in the insertion direction Z. This leads to a movement of the locking tab 67 in the direction of the rest position of the retaining pin 56, wherein the locking tab 67 leaves the return section 60 and in the Auslenkh section 59 opposite Ausführabschnitt 62 passes. This opens into an outlet opening 63 through which the locking tab 67 can leave the guide groove 55, so that a removal of the base 15 from the socket 14 is possible.

As described above, however, the Ausführabschnitt 62 of the locking tab 67 forces a movement, which in turn leads to a deflection of the retaining pin 56 and to build a spring tension. This spring tension is suitable for holding the mounting dome 51 against the spring tension of the pressure plate 68 and / or against any gravitational force in the socket 14, so that a failure of the socket 15 from the socket 14 is avoided (FIG. Fig. 14 ).

Now, an additional force is applied by the user, which dissolves the base 15 of the socket 14 and leads to a sliding out of the locking tab 67 of the guide groove 55. After this release of socket 15 and socket 14, the lamp 11 in turn has a light 10 inclined position (see Fig. 2 ).

Now, the anchor head 38 can be moved against the insertion direction X from the holding space 31 out into the insertion portion 27. The guide surfaces 30 reverse the direction of movement in a withdrawal direction which is opposite to the insertion direction Y. The anchor head 38 leaves the holder 12 through the opening 26, whereupon the mechanical connections between the lamp 11 and lamp 10 are canceled.

If a holder 12 with spring element 40 has found use, the spring arm 41 supports the movement against the insertion direction X and induces the disassembly movement. In addition, the spring arm 41 also pushes the anchor head 38 out of the holding space 31 and into the insertion section 27, when the lamp is inadvertently released from the socket 14 when the base 15 is released. In this way it is prevented that the forces exerted by such a dropping of the lamp and the resulting pivoting movement on the holder 12 and in particular their webs 29 destroy the latter. Even with such a misoperation is thus ensuring that the holder 12 and thus the lamp remains intact.

As has been shown, the base 15 and the socket 12 serve the mechanical anchoring of the lamp 11 in the lamp 10 by a very advantageous operating concept, which is also known as a push-in push-out operating concept. This means that both for anchoring and for loosening the base 15 must be pressed into the socket 14. It is therefore obvious that, omitting socket contacts and base contacts and corresponding contact carrier components, it is possible to form a holding part and a holder which correspond to the base 15 and the socket 14 with regard to the components which are responsible for the mechanical anchoring. The use of such configured holder and holding part must therefore be regarded as equivalent to the use of socket and socket.

In addition, it is at any time apparent to those skilled in the art that the subject embodiment of the socket can be realized on the socket side and the objective embodiment of the socket can be realized on the front, without resulting in disadvantages or special design requirements. Even such a solution would therefore be considered equivalent.
