License unit for a vehicle headlamp
The invention relates to a light unit for a vehicle headlamp, wherein the light unit has at least one lamp with at least one light source and at least one igniter and at least one reflector unit with at least one opening for inserting the light source of the lamp. The invention also relates to a lamp holder and a retaining spring device for such a light unit for use in vehicle headlights.
A number of solutions for mounting lamps, in particular gas discharge lamps, in light units or in vehicle headlights are known from the prior art. This is done mainly by inserting the lamp in a reflector module and attaching the lamp in the module with a spring element, such as a sheet metal spring. AT 506 319 Bl shows such a lamp holder, which is made of a conductive material and releasably fixes a lamp to a reflector of a vehicle headlamp. The lamp holder is plugged in the direction of the optical axis of the lamp and locked to the reflector or clamped the lamp. The lamp holder creates a conductive connection between the lamp and the reflector so that electromagnetic shielding of the lamp is achieved.
The shield is used for electromagnetic compatibility (EMC) of the headlamp or the lamp. EMC refers to the problem that, when the arc is ignited, gas discharge lamps produce electromagnetic interference radiation in addition to the light which can affect the sensitive electronic vehicle systems. Therefore, an attempt is made to shield the lamps accordingly, in order to reduce or completely eliminate the interference. Solutions without the above-mentioned spring elements are shown in DE 10 2008 020 001 A1 and DE 10 2007 022 028 A1, in which the lamp is fixed in the reflector by a rotary movement about the optical axis of the lamp, whereby latching elements to the lamp and the reflector are fixed. I «·· ···» * *·· * · «* ·····« · * * 1Ί2217 DF 10 2007 022 028 Al shows a lamp fixture in which a lamp carrier and a contact plate for KMV contacting are provided between the lamp and the reflector. A clamping element in the lamp carrier described above holds in an end position, which is achieved by turning the lamp in the bulb holder. The disadvantage of this is in particular that several items are provided, which are difficult to assemble and - which is a problem especially when Klemmelcment - can easily be lost.
In the solution according to DE 10 2008 020 001 Al locking elements on the reflector neck, which is part of the reflector, bayonet with corresponding elements on T.ampensockel together. The lamp is inserted into the reflector; during a subsequent rotational movement about the optical axis of the reflector, the locking elements engage each other, so that the lamp is positioned relative to the reflector in the axial and also in the radial direction. The attachment of the lamp to the reflector thus takes place without additional, separate from the reflector and lamp fasteners. This solution has the disadvantage that the lamp must be specially made and the attachment for older lamps is not usable. Thus, a problem-free interchangeability is not given. HP 1 081 428 Λ2 shows a solution from a related field in which the light source of a (gas) discharge lamp can be fixed in a starting device by means of a bayonet lock and is thus easily exchangeable. The ignitor includes the necessary for the operation of the lamp electronics; the assembly in the vehicle headlight is obviously on the ignitor, which is said about the connection between ignitor or lamp and vehicle headlights nothing.
All these solutions have in common that they either consist of a large number of individual parts or require a special design of the lamps.
It is therefore an object of the invention to provide a lighting unit for a vehicle headlight, can be easily and inexpensively attached to the lamps of various kinds.
This object is achieved with a light unit mentioned in the introduction according to the invention by virtue of the fact that at least one in the mounted state comprises at least the igniter '(1 * * 1' * .phi. Φ * * * «Φ I II * # * · * φ · φ φ φφ φφ -3-
Lampholder is provided with extending in the direction of the reflector unit first locking means and on the back of the reflector unit corresponding second Verriegclungsmittel are arranged, wherein the first locking means are engageable during assembly by means of a rotary movement of the lamp holder about the longitudinal center axis of the reflector unit with the second locking means, The reflector unit is a reflector or a reflector arranged in a reflector adapter. The second locking means are arranged on the rear side of the reflector or on the rear side of the reflector adapter. Rear side is to be understood here in the mounted state of the light unit as the directed against the forward direction side.
The invention enables a fastening of the lamp by means of a bayonet lock on the reflector or on the reflector adapter - by turning the locking means act together and can be easily solved by turning in the opposite direction again. The fact that the Verricgelungsmittel are arranged on the lamp holder, any lamps can be used, which need not be specially prepared for the bayonet - the only condition is that the lamps fit into the lamp holder, thereby ensuring that the igniter of the lamps is not standardized, but defined by a maximum size. The holder of the lamps via the igniter. At the same time it is ensured for the user that the lamp is optimally adjusted in the reflector when mounted by means of rotary motion. The solution according to the invention is simple and inexpensive to implement and allows easy lamp mounting, or a simple lamp replacement.
The longitudinal center axis of the reflector unit essentially corresponds to the main emission direction and thus, so to speak, to the optical axis of the light unit. It runs in the assembled state of the light unit in a vehicle parallel to the direction of travel. For reasons of clarity and comprehensibility, the term longitudinal center axis is used below, but in each case encompasses the optical axis or main emission direction.
Due to the fact that the weight distribution of conventional discharge lamps due to the construction of the heavy igniter and the comparatively light source is strongly on the side of the igniter, it is a further advantage of the subject invention that it allows the lamp to be held over the igniter. This will allow proper positioning of the light source. - / ΙΊ2217 -4-
Vortrochafterweise the first locking elements are designed as locking lugs and the second locking elements as locking openings, or vice versa. Variants in which the first locking elements are partially designed as locking lugs and partially as locking openings (and the second locking elements in a corresponding manner) are possible. In a variant of the invention, the locking lugs have rising latching edges and are adapted to act in a clamping manner during the rotational movement during assembly with the latching openings. This means that with increasing rotation, the locking lugs are pressed against the locking openings, thus allowing a stable connection between the lamp holder and the reflector unit.
In a further variant of the invention, the first locking means are locking lugs and the second locking elements are locking openings, each having an insertion area and a locking receptacle, wherein the Verricgelungsnasen of the lamp holder at the same time when inserting the light source through the opening in the reflector unit introduced into the insertion be rotated and rotated by means of the rotational movement about the longitudinal center axis of the reflector unit in the clamp receptacle and so with the locking openings fixing cooperation. As a result, a bayonet closure is realized, which is also easy to solve by the lamp holder is rotated against the direction in which the assembly takes place, so that the locking lugs are again in the insertion and the lamp and lamp holder along the longitudinal central axis of the reflector unit from Reflector (or the reflector adapter) can be separated. Conveniently, the lamp holder has four first locking elements and the reflector unit has four corresponding second locking elements. The elements are conveniently arranged in pairs opposite each other. This makes it possible to realize a particularly stable attachment.
In a variant of the invention, the lamp holder has a recess on its side facing away from the reflector unit in the mounted state. This recess serves on the one hand to save material, on the other hand, so the simple reading of attached to the lamp or the detonator information is possible. 1 PI 2217 »· -5-
In order to enable optimum positioning of the lamp, at least one retaining spring device with a base plate and side elements projecting in the direction of the reflector unit is provided between the lamp holder and the lamp. The lever presses the lamp into position on the reflector unit and ensures high positioning repeatability when changing the lamp. At the same time the lamp is pressed down by the Halteklammcr, wherein the term below refers here to the mounting position Lichteinheil in the vehicle. By the retaining spring device is also ensured that detonators of different sizes (which are defined by a maximum) are held firmly.
Since the lamp holder is firmly bayoneted with the reflector unit (ie the reflector or the reflector adapter), the spring force of the retaining spring device between the lamp holder and lamp can fully unfold and cause a good attachment. The retaining spring device may, in principle, be formed from any flexible, conductive material, such as sheet metal. Other materials are possible as long as they are conductive (or have conductive regions, for example plastic with a conductive coating) and have sufficient strength for the function of the retaining spring device.
The side elements have at their ends facing away from the base plate resilient clamping devices. The side members of the retaining spring device are provided on opposite sides of the base plate. In this case, two or four side elements are favorably provided by the clamping devices of the side elements, the retaining spring device can be optimally connected to the lamp or its detonator and support their proper positioning. When two side elements are provided, they are arranged on the base plate at the top and bottom or left and right - the location information relates to a view of the base plate in the mounted state of the retaining spring device or a light unit in use. For example, if two side members are provided at the top and bottom of the base plate, the top side member may be made wider so that it generates more force and therefore pushes the lamp down. At least one of the side elements can be designed in two parts to release a plug for the detonator. 1 9 * ····································································································································································································································· · · -6-
In a variant of the invention, at least one recess is provided in the base plate of the ITaltefedervorrichtung and in the recess at least one positioning spring element is arranged, which is parallel to the longitudinal central axis of Rcflektoreinhcit acting in the direction of the reflector unit. Conveniently, a pair of Positionierungsfederelemcnten each arranged in the upper and in the lower region of the recess of the base plate. These positioning spring elements assist the positioning accuracy of the lamp in its mounting position in the reflector unit (ie on the reflector or on the reflector adapter) and prevent tilting of the lamp, in particular also in the subsequent attachment of plugs (for example on the igniter, as described above). The positioning spring elements can for this purpose have round elevations, which prevent tilting of the springs on the lamp housing. "Upper Platen " and "lower range " are to be understood here starting from the orientation of the light unit in an assembled state. In addition to the top and bottom, of course, right and left and combinations of it are possible.
For reasons of electromagnetic compatibility, or because of the above-described problem of electromagnetic interference by gas discharge lamps, the retaining spring device is configured in a variant of the invention that on the Seitenelementc or on the positioning spring elements and the side elements in the assembled state, a conductive connection between the igniter and Produce reflector. For this purpose, either the side elements contact directly the igniter and the reflector, or the conductive connection to the reflector via the positioning spring elements on the back of the igniter and the side elements (if, for example, an optimal contacting by the side elements alone is not possible). The EMC problem, which is solved by it, has already been described in detail at the beginning.
In a variant of the invention, at least one secondary latch is provided on the base plate for making contact with a plug contact or for supplying energy to the lamp. Thus came also a "grounding". The light unit can be made by contacting the shield of cables connected there through the secondary latching.
In addition to or instead of the conductive connection between the Ilialtefedervorrichtung and reflector can - depending on the embodiment - between the lamp and reflector at least one Lcitungselement be provided which establishes a conductive connection between the igniter and the reflector. This line element can, for example, ring-shaped as "EMV- PI 2217 1
• «• t • * •»
* * * i * * -7-
Ring " be executed and mounted during assembly between the lamp and reflector. The cable element is obviously made of a conductive material.
By the above features, for example, a grounding of the light unit is possible by a conductive element between the reflector and detonator is made via a line element and a connection to the ground via the Haltefedervorrichtung and in particular their Sekundärver-rastung connected via a Sekundärvcrrastung, shielded cable on the vehicle.
The lamp holder is made of plastic or metal. For example, the lamp holder can be designed as a metallic die-cast. The retaining spring device is conveniently made of a conductive material. Preferably, the retaining spring device is made of sheet metal and the lamp holder is designed as a plastic part.
The abovementioned object is likewise achieved by a lamp holder or a retaining spring device mentioned at the outset for use in a vehicle headlight with the abovementioned features.

Fig. 1 shows an overall perspective view of a light unit 1 for a vehicle headlight obliquely from the front. The unit is closed to the front of a arranged in a lens holder 3 (projection) lens 2. The lens holder 3 is mounted on a reflector unit consisting of a reflector adapter 4 and a reflector 5 arranged therein. With dotted line the longitudinal center axis X of the reflector unit is shown. The longitudinal central axis of the reflector 5 or reflector adapter 4 coincides with the main beam direction of the light unit 1. For reasons of clarity and for better location, however, the term "longitudinal central axis" is used here throughout. used.
In the following embodiment, the variant is described in which the lamp holder via the reflector adapter 4 takes place - the reflector unit therefore has a reflector adapter 4 and a reflector 5 supported therein. For the sake of completeness, it should be pointed out that the solution according to the invention is also applicable to variants in which the reflector unit consists only of a reflector 5, but this has no influence on the function according to the invention.
At the back of the reflector adapter 4 are the devices according to the invention for holding the lamp 7, namely the lamp holder 9 together with Haltefedcrvorrichtung. 8
As will be described below, the lamp 7 is mounted on the reflector unit (ie on the reflector 5 or reflector adapter 4) by means of a bayonet closure - the lamp 7 is connected to the lamp holder 9 and holding spring device 8 along the longitudinal center axis X of FIG

Reflector Einein introduced, by turning about the longitudinal center axis X locking elements engage the lamp holder 9 and the reflector adapter 4 locking together. After a brief description of the individual components of the light unit 1 according to the invention a more detailed representation of the bayonet closure takes place.
Lamp holder 9 and Ilaltefedcrvorrichtung 8 can be better seen in Fig. 2, in which a perspective view is shown obliquely from behind. Here, between the lamp holder 9 and retaining spring device 8 through a recess 11 in the lamp holder 9 of the igniter 7 'of the lamp 7 can be seen, which is encompassed by the lamp holder 9. Thanks to the recess 11, information can be read from the back of the igniter 7 ', e.g. the dot matrix code of the built-in lamp 7.
The perspective exploded view in Fig. 3 shows (apart from the reflector adapter 4, which is omitted for reasons of clarity), the individual components of the lighting unit 1 according to the invention:
The lamp 7, which is a discharge lamp, consists of igniter 7 'and light source 7 ". During assembly, the lamp 7 is guided through an opening 10 in the reflector 5 to a substantially circular lamp support 40 and then fixed. The lamp support 40 is the exact reference surface along the longitudinal center axis X of the light unit 1. The lamp 7 must come to rest with its reference points on the lamp support 40 properly. The lamp support 40 thus serves as a stop for the lamp 7 or its detonator 7 '; When mounting so the attachment of the lamp 7 by means of lamp holder 9 takes place against this lamp support 40th
To ensure that the appropriate for the light unit 1 lamp 7 is properly introduced, the lamp 7 is referenced to the reflector 5 (or the socket area). For this purpose, in the region of the opening 10 in the reflector 5 (or in the reflector adapter 4) coding means 30 (see Figures 8 and 9) are arranged - in the figures 8 and 9, a plurality of coding means 30 is provided. These are easy to break out and will be removed depending on the intended lamp type or not.
A line element 6 is provided between the lamp 7 and the reflector 5 - in this case a conductive ring (FIG. 10), which is responsible for a conductive connection between the lamp 7 and the reflector 5. [001] »
Fl 2217 ψ «* * · ... · · · · · · · · · · · · · · · · · · · · ·. To ensure the connection contact elements in the form of protruding buttons 60, 60 'are provided. The conductive ring and the conductive connection to the reflector 5 serve to ensure the electromagnetic compatibility of the lamp 7:
In today usual discharge lamp, which is usually a common assembly of light source 7 " and igniter 7 ', there are often electromagnetic compatibility problems in the area of the power supply circuits associated with the lamp 7. By the high voltage necessary for the operation of the lamp 7 or in the ignition of the arc electromagnetic waves are radiated, which influence as noise electronic devices of the vehicle or -. in the case of airbags, sensors, etc. - may interfere with their proper functioning. It is therefore necessary to shield these electromagnetic emissions in the area of the lamp 7 by means of specific shielding devices. The reflector 5, which usually consists of a conductive material (for example metal diecasting) or is provided with a conductive layer, serves for this purpose. The line element 6 connects the lamp 7 and the reflector 5; As will be described below, the shielding can also be done differently or with additional means.
For fixing the lamp 7 in the reflector unit (in this case in the reflector adapter), the lamp holder 9 and the holding spring device 8, which comprise the igniter 7 'or the lamp 7, are fixed with the reflector unit.
The lamp holder 9 (see Figures 4 and 5) is preferably made of plastic and designed so that it comprises the igniter 7 'of the lamp 7. The lamp holder 9 has first locking means, which are designed in the illustrated embodiment as locking lugs 12, wherein two locking lugs 12 are provided opposite each other. In the mounted state of the lamp holder 9, the locking lugs 12 extend in the direction of the reflector 5 or reflector adapter 4. At the side facing away from the reflector 5 side of the lamp holder 9, the above-mentioned recess 11 is executed.
The retaining spring device 8 is shown in Figures 6 and 7 in perspective views. The retaining spring device 8, which is preferably made of sheet metal or another conductive material, has a base plate 13 with side elements 14, 14 'protruding therefrom. In the present exemplary embodiment, two side elements 14, 14 'are provided, which are conveniently arranged opposite one another - the side elements 14, 14' '1' '' '' '*. * * * * *' 121217 '*. For example, they can be arranged on the base plate 13 at the top and bottom (if necessary also right and left). The information "top " and "below" or "right" and "left" refer to the arrangement of the device in Figures 6 and 7. For example, if four side elements 14,14 'are provided, they can be arranged above, below, left and right. Before mounting the lamp 7, the Haltefedervor-device 8 is first attached to the igniter 7 'of the lamp 7 (see Fig. 11), then the lamp holder 9 is attached and the assembly can take place. In a preferred variant, first the retaining spring device 8 is mounted in the lamp holder 9 (see FIG. 12) and only then attached to the igniter 7 '. For captively holding the retaining spring device 8, the retaining spring device 8 resilient stop elements 24 which engage after insertion of the retaining spring device 8 in the Lampcnhalter 9 with corresponding stop openings or stops in the lamp holder 9. As a result, loss of security is given, which by depressing the stop elements 24 again a release of the retaining spring device 8 from the lamp holder 8 is possible.
This makes it easy to realize a lamp exchange, since simply the combination of lamp holder 9 and retaining spring device 8 subtracted from the igniter 7 'of the defective lamp 7 and the new lamp 7 is pre-assembled in the lamp holder IIaltefedervoragekombination. Then the lamp 7 is mounted again on the socket.
For proper attachment to the igniter 7 ', the Seitcnelemente 14, 14' at their remote from the base plate 13 ends resilient clamping devices 15,15 ', which attack the igniter 7' behind. The lower side member 14 'is for receiving plug contacts for the lamp 7, e.g. for the igniter 7 ', divided into two and includes an exemption for the plug. For the plug, a Sekundärverrastung 21 is further provided for contacting. If a plug with associated, shielded cable is connected to the plug contact, the secondary catch 21 locks with this plug or its shield.
In a variant of the invention, which is not shown in the figures, the side members 14, 14 'can be extended so that they touch the reflector 5 of the light unit 1 in the assembled state - in that the side members 14, 14' clamp the igniter 7 'of the lamp 7, so in the sense of EMC, a conductive connection between the lamp 7 and reflector 5 can be made, in addition to or instead of the line 1 • · * * * «* V« * * Γ12217
* * B * * * * * * ft * t * * • * * t * 12 elements 6 can be provided. In addition to the illustrated, other arrangements and solutions of Seitenelcmente 14,14 'are possible.
In the base plate 13, a recess 16 is provided in the positioning spring elements 17, 18, 19, 20 are arranged. The positioning spring elements 17,18,19, 20 are designed as wide Federblättcr acting in a direction parallel to the longitudinal center axis X of the reflector unit or the reflector 5 in the direction of the reflector unit - the positioning spring elements 17, 18, 19, 20 press so in the assembled state the lamp 7 in the direction of the reflector unit and ensure a firm grip of the lamp 7. This also prevents tilting of the lamp 7, for example when attaching a plug (see above). In the illustrated embodiment, the positioning spring elements 17, 18, 19, 20 are arranged in pairs in the upper and lower region of the recess 16 - the terms "top". and "below" refer again to the orientation of the retaining spring device 8 in Figures 6 and 7. The positioning spring elements 17, 18,19, 20, which touch the igniter 7 'of the lamp, in conjunction with the Seitenelcmenten 14, 14', the conductive contact of the Reflectors 5 are particularly well realized.
In connection with the line element 6, a further variant of the contacting or shielding can be realized via the positioning spring elements 17, 18, 19, 20 as follows: the line element 6 establishes a conductive connection between the reflector 5 and the igniter 7 '; via the side elements 14,14 ', possibly in combination with the positioning spring elements 17, 18, 19, 20, a conductive connection of the igniter 7' with the retaining spring device 8 is realized; Secondary locking 21 is used to connect to the shielding of a cable and thus to grounding of the vehicle.
The aforementioned bayonet closure will now be explained in more detail with reference to Figures 1, 2, 4, 5, 8 and 9. The bayonet closure is realized as a connection between the lamp holder 9 and Reflektoreinhcit (reflector 4 or reflector adapter 5). The variant with the reflector adapter 5 is described below. In the ready-to-use light unit 1 is located in the reflector adapter 5, a reflector 4, the assembly of the lamp 7 is then in the reflector 4 and the adapter - for reasons of clarity, however, the reflector 4 is recessed in Figures 8 and 9. 1 * 1 · * i | «* * * *· * * * * P12217 *» ·· ** ·· * * * «···« * * * *% I «* *« I · * * -13-
The lamp holder 9 has first locking elements (the locking lugs 12 described above), which cooperate with corresponding second Verriegelungsclementen on the back of the reflector unit - in the present ball with arranged on the back of the reflector 4 in the reflector adapter 5 second locking elements.
The second locking elements are designed as locking openings 22, which are provided according to the number and arrangement of the locking elements 12 of the lamp holder 9.
As can be seen in FIG. 9, the locking openings 22 each have an insertion region 220 and a clamping receptacle 221 - during the import of the lamp 7 mounted in the lamp holder 9 through the opening 10 in the reflector 4 along the longitudinal central axis X of the reflector (see FIG. 3) at the same time the locking lugs 12 introduced into the insertion areas 220 of the locking openings 22. FIG. 13 shows a detailed view of a locking opening 22 with a contact area 220 and a clamping receptacle 221. FIG. 13 shows the area marked by the dot-dashed circle in FIG. 9. Then, when the lamp holder 9 and lamp 7 are rotated about the longitudinal center axis X of the reflector unit, the locking lugs 12 move into the clamping receptacles 221 and thus interact with the locking openings 22 together fixing. The lamp holder 9 (and the retaining spring device 8) thus exert a pressure on the lamp 7 along the longitudinal center axis X of the reflector 5 in the direction of the reflector 5 and cause a secure mounting of the lamp 7.
In order to enhance this fixation, the locking lugs 12 may be formed with rising locking edges 23, as can be seen in Fig. 5 - the " thickness " the locking edge 23 increases in the circumferential direction and seen in the radial direction. Thus, when the locking lug 12 comes into the clamping receptacle 221 when rotating about the longitudinal center axis X of the reflector unit, the latching edge 23 acts increasingly clampingly with the clamping receptacle 221 with increasing rotation and ensures a secure hold of the bayonet catch. At the same time, the closure is again easily releasable by turning in the opposite direction.
In the case shown in the figures, four locking lugs 12 and four corresponding VerTiegelungsöffnungen 22 are provided in each case. Λ PI2217 ψ * «* ·» »· · f ··· ········ · ·«
As already mentioned, more or less such devices can be provided. Combinations are also possible in which the locking lugs 12 are arranged partly on the lamp holder 9, partly on the reflector unit (ie on the reflector adapter 4 or on the reflector 5). As described above, the second locking elements can also be arranged on the reflector 5 instead of (as shown) on the reflector adapter 4. In the selected locking variants must be ensured that the lamp 7 with a uniform pressure on the reflector 5 and the lamp support 40 (see Fig. 3) presses and there is no tilting or disturbance of the light image due to the bayonet.
