Description

Die Erfindung betrifft eine LED-Lampe (LED: Licht emittierende Diode) nach dem Oberbegriff des Anspruchs 1.The invention relates to an LED lamp (LED: light-emitting diode) according to the preamble of claim 1.

LED-Lampen sind aus dem Stand der Technik als solche bekannt. Beispielsweise kennt man LED-Lampen, die mit einem von herkömmlichen Glühlampen bekanntem Standard-Sockel ausgestattet sind, so dass sie als Ersatz für Glühlampen verwendet werden können.LED lamps are known in the art as such. For example, LED lamps are known which are equipped with a standard socket known from conventional incandescent lamps, so that they can be used as a replacement for incandescent lamps.

Bei derartigen LED-Lampen erfolgt eine mit Bezug auf die Hauptachse des Sockels symmetrische Lichtabgabe. Sofern eine andersartige Lichtabgabe gewünscht ist, ist hierfür ein weiteres spezielles Element erforderlich.In such LED lamps symmetrical with respect to the main axis of the base light output takes place. If a different type of light output is desired, this requires a further special element.

Der Erfindung liegt die Aufgabe zu Grunde, eine LED-Lampe anzugeben, mit der eine alternative Art der Lichtabgabe möglich ist.The invention is based on the object to provide an LED lamp, with an alternative type of light output is possible.

Diese Aufgabe wird gemäß der Erfindung mit der in dem unabhängigen Anspruch angegebenen LED-Lampe gelöst. Besondere Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved according to the invention with the LED lamp specified in the independent claim. Particular embodiments of the invention are indicated in the dependent claims.

Gemäß der Erfindung ist eine LED-Lampe vorgesehen, die ein LED-Modul als Lichtquelle und einen Sockel mit einem Gewinde aufweist. Die LED-Lampe ist dabei derart ausgebildet, dass Licht, das von dem LED-Modul abgegeben werden kann, mit Bezug auf die durch das Gewinde festgelegte Hauptachse asymmetrisch abgegeben wird.According to the invention, an LED lamp is provided which has an LED module as a light source and a socket with a thread. The LED lamp is designed in such a way that light which can be emitted by the LED module is emitted asymmetrically with respect to the main axis fixed by the thread.

Auf diese Weise ist eine Lichtabgabe ermöglicht, die im Vergleich zu den bekannten LED-Lampen andersartig ist.In this way, a light output is possible, which is different compared to the known LED lamps.

Vorzugsweise ist dabei die LED-Lampe derart ausgebildet, dass das LED-Modul gegenüber dem Sockel drehbar gelagert ist. Hierdurch lässt sich die Richtungsabhängigkeit des abgegebenen Lichts verändern, wenn die LED-Lampe mit ihrem Sockel in einer entsprechenden Fassung eingeschraubt ist.Preferably, the LED lamp is designed such that the LED module is rotatably mounted relative to the base. As a result, the directional dependence of the emitted light can be changed when the LED lamp is screwed with its socket in a corresponding version.

Dabei ist die LED-Lampe vorzugsweise derart ausgebildet, dass das LED-Modul gegenüber dem Sockel durch einen Anschlag begrenzt drehbar gelagert ist. Hierdurch lässt sich erzielen, dass die LED-Lampe - nachdem das LED-Modul bis zum Anschlag gedreht worden ist - durch einfaches Weiterdrehen in eine Fassung eingeschraubt werden kann, ohne dass die LED-Lampe hierzu am Sockel ergriffen werden müsste.In this case, the LED lamp is preferably designed such that the LED module relative to the base is limited rotatably supported by a stop. In this way it can be achieved that the LED lamp - after the LED module has been turned to the stop - can be screwed by simply turning further into a socket without the LED lamp would have to be taken for this purpose sockets.

Vorzugsweise ist dabei der Anschlag derart ausgebildet, dass die Drehbarkeit des LED-Moduls gegenüber dem Sockel auf 360° oder auf weniger als 360°, beispielswiese auf einen Winkelbereich von zwischen 340° und 360° begrenzt ist. Hierdurch wird erzielt, dass die Lichtabgabe praktisch in jede mögliche seitliche Richtung eingestellt werden kann, wenn die LED-Lampe in eine Fassung eingeschraubt ist.Preferably, the stop is designed such that the rotation of the LED module with respect to the base to 360 ° or less than 360 °, for example, limited to an angular range of between 340 ° and 360 °. This achieves that the light output can be adjusted in virtually any possible lateral direction when the LED lamp is screwed into a socket.

Vorzugsweise weist der Sockel zwei elektrische Pole auf, wobei zur elektrischen Verbindung zwischen den beiden Polen und dem LED-Modul wenigstens ein Schleifkontakt angeordnet ist. Hierdurch lässt sich eine zuverlässige elektrische Verbindung zwischen den Polen des Sockels und dem LED-Modul sicherstellen, und zwar insbesondere, wenn das LED-Modul gegenüber dem Sockel verdreht werden kann, in jeder Drehstellung des LED-Moduls.Preferably, the base has two electrical poles, wherein at least one sliding contact is arranged for electrical connection between the two poles and the LED module. This makes it possible to ensure a reliable electrical connection between the poles of the base and the LED module, in particular, when the LED module can be rotated relative to the base, in each rotational position of the LED module.

Weiterhin ist es von Vorteil, wenn die LED-Lampe außerdem einen Kühlkörper zur Kühlung des LED-Moduls aufweist. Vorzugsweise weist dabei der Kühlkörper zur Handhabung der LED-Lampe einen Oberflächenbereich auf, der elektrisch isoliert ist. Hierdurch lässt sich der Kühlkörper so gestalten, dass er zum Einschrauben der LED-Lampe in eine Fassung direkt mit einer Hand angegriffen werden kann. Dies hat im Weiteren zur Folge, dass der Kühlkörper vergleichsweise groß gestaltet werden kann, weil er einen Außenbereich der Lampe darstellen kann. Hierdurch wird erzielt, dass der Kühlkörper besonders effektiv Wärme vom LED-Modul abführen kann. Vorzugsweise weist der Kühlkörper - normal zur Hauptachse betrachtet - eine größere Querschnittfläche auf als der Sockel. Hierdurch lässt sich der Kühlkörper besonders groß und somit besonders effektiv gestalten.Furthermore, it is advantageous if the LED lamp also has a heat sink for cooling the LED module. In this case, the heat sink for handling the LED lamp preferably has a surface area which is electrically insulated. As a result, the heat sink can be designed so that it can be attacked for screwing the LED lamp into a socket directly with one hand. This has the consequence that the heat sink can be made comparatively large because it can represent an outdoor area of the lamp. This ensures that the heat sink can dissipate heat from the LED module particularly effective. Preferably, the heat sink - viewed normal to the main axis - a larger cross-sectional area than the base. As a result, the heat sink can be made particularly large and thus particularly effective.

Vorzugsweise ist das LED-Modul mit Bezug auf die durch das Gewinde festgelegte Hauptachse asymmetrisch angeordnet. Dies ermöglicht eine insgesamt besonders raumsparende Aufteilung der Bauteile der LED-Lampe, so dass sich die LED-Lampe - bei gegebener Effektivität - vergleichsweise klein gestalten lässt. Beispielsweise kann vorgesehen sein, dass das LED-Modul und der Kühlkörper eine Ebene durchsetzen, die normal zu der Hauptachse verläuft, die durch das Gewinde festgelegt ist.Preferably, the LED module is arranged asymmetrically with respect to the main axis defined by the thread. This allows a total of particularly space-saving division of the components of the LED lamp, so that the LED lamp - for a given effectiveness - can make comparatively small. For example, it can be provided that the LED module and the heat sink pass through a plane which is normal to the main axis, which is determined by the thread.

Vorzugsweise ist das LED-Modul derart angeordnet, dass Licht, das von dem LED-Modul erzeugt werden kann, überwiegend in eine Richtung abgestrahlt wird, die mit der Hauptachse einen Winkel von mindestens 20°, vorzugsweise mindestens 45°, beispielswiese 90° einschließt. Hierdurch lässt sich eine deutlich zu einer Seite gerichtete Abstrahlung bewirken.Preferably, the LED module is arranged such that light which can be generated by the LED module is emitted predominantly in a direction which includes an angle of at least 20 °, preferably at least 45 °, for example 90 ° with the main axis. This can cause a clearly directed to one side radiation.

Vorzugsweise weist die LED-Lampe weiterhin eine Abdeckung des LED-Moduls auf, die zum Schutz und/oder als optisches Element dient. Vorzugsweise ist dabei die Abdeckung zumindest teilweise transparent oder lichtstreuend.Preferably, the LED lamp further comprises a cover of the LED module, which serves for the protection and / or as an optical element. Preferably, the cover is at least partially transparent or light scattering.

Vorzugsweise weist die LED-Lampe weiterhin ein Elektronik-Modul, beispielsweise in Form einer Konstantstromquelle, zur elektrischen Versorgung des LED-Moduls auf, wobei das Elektronik-Modul vorzugsweise am Kühlkörper angeordnet ist.Preferably, the LED lamp further comprises an electronic module, for example in the form of a constant current source, for the electrical supply of the LED module, wherein the electronic module is preferably arranged on the heat sink.

Dabei weist die LED-Lampe vorzugsweise außerdem ein weiteres Elektronik-Modul, beispielsweise in Form eines Konverters, zur Speisung des zuerst genannten Elektronik-Moduls auf.In this case, the LED lamp preferably also has a further electronic module, for example in the form of a converter, for feeding the first-mentioned electronic module.

Die Erfindung wird im Folgenden anhand eines Ausführungsbeispiels und mit Bezug auf die Zeichnung näher erläutert. Es zeigt

Fig. 1
einen schematischen Längsschnitt durch ein Ausführungsbeispiel einer erfindungsgemäßen LED-Lampe.
The invention is explained in more detail below with reference to an embodiment and with reference to the drawing. It shows
Fig. 1
a schematic longitudinal section through an embodiment of an LED lamp according to the invention.

In Fig. 1 ist schematisch ein Längsschnitt durch ein Ausführungsbeispiel einer erfindungsgemäßen LED-Lampe skizziert. Die LED-Lampe weist als Lichtquelle ein LED-Modul 2 auf. Das LED-Modul 2 umfasst wenigstens eine LED. Weiterhin umfasst die LED-Lampe einen Sockel 8, der ein Gewinde, beispielswiese ein Außengewinde aufweist. Der Sockel 8 kann insbesondere ein Standard-Sockel sein, wie er derzeit bei herkömmlichen Glühlampen verwendet wird. Hierdurch lässt sich die LED-Lampe so gestalten, dass sie zum Betrieb in entsprechende herkömmliche Fassungen eingeschraubt werden kann.In Fig. 1 schematically a longitudinal section is sketched by an embodiment of an LED lamp according to the invention. The LED lamp has a LED module 2 as the light source. The LED module 2 comprises at least one LED. Furthermore, the LED lamp comprises a base 8, which has a thread, for example an external thread. The base 8 may in particular be a standard socket, as it is currently used in conventional light bulbs. As a result, the LED lamp can be designed so that it can be screwed for operation in corresponding conventional versions.

Durch das Gewinde des Sockels 8 bzw. durch die Längsachse des Gewindes ist eine Hauptachse L festgelegt, die insbesondere eine Längsachse des Sockels 8 und eine Längsachse der LED-Lampe bilden kann. Die LED-Lampe ist derart ausgebildet, dass Licht, das von dem LED-Modul 2 abgegeben werden kann, mit Bezug auf die Hauptachse L asymmetrisch abgegeben wird. Hierdurch lässt sich mit der LED-Lampe eine Lichtabgabe erzeugen, die mit Bezug auf die Hauptachse L, nicht - wie bei bisherigen LED-Lampen üblich - symmetrisch ist. Beispielsweise kann das LED-Modul 2 derart angeordnet sein, dass die Lichtabgabe überwiegend in lediglich eine Richtung erfolgt, die mit der Hauptachse L einen Winkel größer Null einschließt, beispielsweise einen rechten Winkel einschließt. Mit Bezug auf das in Fig. 1 gezeigte Beispiel ist das LED-Modul 2 derart angeordnet, dass die Lichtabgabe überwiegend nach rechts erfolgt, wobei der Winkel zwischen der Richtung der überwiegenden Lichtabgabe und der Hauptachse 90° beträgt.Through the thread of the base 8 and through the longitudinal axis of the thread, a main axis L is fixed, which can form in particular a longitudinal axis of the base 8 and a longitudinal axis of the LED lamp. The LED lamp is configured such that light that can be output from the LED module 2 is emitted asymmetrically with respect to the main axis L. As a result, can be generated with the LED lamp, a light output, with respect to the main axis L , not - as usual in previous LED lamps - symmetrical. For example, the LED module 2 may be arranged such that the light output predominantly takes place in only one direction, which with the main axis L encloses an angle greater than zero, for example enclosing a right angle. With reference to the in Fig. 1 shown example, the LED module 2 is arranged such that the light output is predominantly to the right, wherein the angle between the direction of the predominant light output and the main axis is 90 °.

Beispielsweise kann vorgesehen sein, dass das LED-Modul 2 eine Platine 9 aufweist, deren Flächennormale N nicht parallel zu der Hauptachse L verläuft. Beispielsweise kann - wie in Fig. 1 angedeutet - vorgesehen sein, dass die Platine 9 mit der Hauptachse L einen rechten Winkel einschließt. Hierdurch lässt sich eine Lichtabgabe bewirken, die - mit Bezug auf die Hauptachse L - überwiegend ausschließlich zu einer Seite hin gerichtet ist.For example, it can be provided that the LED module 2 has a circuit board 9 whose surface normal N does not run parallel to the main axis L. For example - as in Fig. 1 indicated - be provided that the board 9 with the main axis L encloses a right angle. This can cause a light output, which - with respect to the main axis L - is directed predominantly to one side.

Außerdem kann vorteilhaft vorgesehen sein, dass die Platine 9 so angeordnet ist, dass sie zu der Hauptachse L einen Abstand a aufweist, der beispielsweise etwa so groß oder mindestens so groß ist wie die Radialerstreckung r des Sockels 8. Durch einen derartigen Abstand a wird erzielt, dass für weitere Bauteile der LED-Lampe besonders viel Raum zur Verfügung steht und somit die LED-Lampe insgesamt vergleichsweise raumsparend gestaltet werden kann.In addition, can be advantageously provided that the board 9 is arranged so that it has a distance a to the main axis L , for example, about as large or at least as large as the radial extent r of the base 8. By such a distance a is achieved in that especially space is available for further components of the LED lamp and thus the LED lamp as a whole can be made comparatively space-saving.

Zur Realisierung der asymmetrischen Lichtabgabe kann vorgesehen sein, dass das LED-Modul 2 mit Bezug auf die Hauptachse L lediglich innerhalb eines Halbraums angeordnet ist. Mit Bezug auf Fig. 1 ist das LED-Modul 2 lediglich in demjenigen Halbraum angeordnet, der sich rechts von der Hauptachse L befindet. Auch dies ermöglicht eine besonders raumsparende Anordnung der Bauteile der LED-Lampe.To realize the asymmetrical light output, it can be provided that the LED module 2 is arranged with respect to the main axis L only within a half space. Regarding Fig. 1 the LED module 2 is arranged only in that half-space, which is located to the right of the main axis L. This also allows a particularly space-saving arrangement of the components of the LED lamp.

Vorzugsweise ist die LED-Lampe derart ausgebildet, dass das LED-Modul 2 relativ zu dem Sockel 8 drehbar gelagert ist. Insbesondere kann die Anordnung derart sein, dass sich das LED-Modul 2 um eine Achse drehen lässt, die zu der Hauptachse L parallel orientiert ist oder - wie im Fall des gezeigten Ausführungsbeispiels - mit der Hauptachse L zusammenfällt. Hierdurch lässt sich erzielen, dass die Abstrahlrichtung verändert werden kann, wenn die LED-Lampe bereits zum Betrieb in eine entsprechende Fassung eingeschraubt ist.Preferably, the LED lamp is designed such that the LED module 2 is rotatably mounted relative to the base 8. In particular, the arrangement may be such that the LED module 2 can be rotated about an axis which is oriented parallel to the main axis L or - as in the case of the embodiment shown - coincides with the main axis L. In this way it can be achieved that the emission direction can be changed if the LED lamp is already screwed into a corresponding socket for operation.

Eine entsprechende Drehbarkeit des LED-Moduls 2 kann beispielsweise durch ein Gleitlager 6 gebildet sein, das beispielsweise am Übergangsbereich des Sockels 8 zur restlichen LED-Lampe angeordnet ist. Das Gleitlager 6 kann beispielsweise einen Lagerkörper in Form eines Ringelements aufweisen und einen hierzu korrespondierenden weiteren Lagerkörper, der gegenüber dem Ringelement beweglich angeordnet ist. Dabei ist vorzugsweise ein (in der Fig. 1 nicht gesondert dargestellter) Anschlag gebildet, der zur Begrenzung eines Winkelbereichs dient, innerhalb dessen das LED-Modul 2 gegenüber dem Sockel 8 verdreht werden kann. Der Anschlag kann beispielsweise an dem Ringelement und/oder an dem weiteren Lagerkörper angeordnet sein. Insbesondere können zwei entsprechende Anschläge vorgesehen sein, so dass der mögliche Drehbereich in beide Drehrichtungen begrenzt ist. Durch eine Begrenzung des Drehbereichs lässt sich erzielen, dass die LED-Lampe leicht in eine entsprechende Fassung eingeschraubt werden kann, indem sie lediglich außerhalb des Sockels 8 angegriffen wird. Hierdurch ist ein Einschrauben in eine entsprechende Fassung erleichtert; entsprechendes gilt für ein Ausschrauben. Vorzugsweise können hierfür die Anschläge derart ausgebildet sein, dass sich das LED-Modul 2 gegenüber dem Sockel 8 um etwa 360° oder etwas weniger als 360° verdrehen lässt. Beispielsweise kann für den maximalen Drehbereich zwischen 340° und 360° vorgesehen sein.A corresponding rotation of the LED module 2 may be formed for example by a sliding bearing 6, which is arranged for example at the transition region of the base 8 to the rest of the LED lamp. The slide bearing 6 may for example have a bearing body in the form of a ring member and a corresponding thereto further bearing body, which is arranged to be movable relative to the ring member. In this case, preferably (in the Fig. 1 not shown separately) stop, which serves to limit an angular range within which the LED module 2 can be rotated relative to the base 8. The stop may be arranged, for example, on the ring element and / or on the other bearing body. In particular, two corresponding stops can be provided, so that the possible range of rotation is limited in both directions of rotation. By limiting the range of rotation can be achieved that the LED lamp can be easily screwed into a corresponding socket by only outside of the base. 8 is attacked. As a result, a screwing is facilitated in a corresponding version; the same applies to unscrewing. Preferably, for this purpose, the stops can be designed such that the LED module 2 can be rotated relative to the base 8 by about 360 ° or slightly less than 360 °. For example, can be provided for the maximum rotation range between 340 ° and 360 °.

Vorzugsweise weist der Sockel 8 zwei elektrische Pole auf, wobei zur elektrischen Verbindung zwischen den beiden Polen und dem LED-Modul 2 wenigstens ein Schleifkontakt 7 angeordnet ist. Hierdurch lässt sich eine elektrische Kontaktierung zwischen den Polen des Sockels 8 einerseits und dem LED-Modul 2 andererseits erzielen, und zwar insbesondere unabhängig von einer Drehstellung des LED-Moduls 2 gegenüber dem Sockel 8.Preferably, the base 8 has two electrical poles, wherein at least one sliding contact 7 is arranged for the electrical connection between the two poles and the LED module 2. This makes it possible to achieve an electrical contact between the poles of the base 8 on the one hand and the LED module 2 on the other hand, in particular independently of a rotational position of the LED module 2 relative to the base 8.

Vorzugsweise weist die LED-Lampe weiterhin einen Kühlkörper 1 zur Kühlung des LED-Moduls 2 auf. Der Kühlkörper 1 kann dabei raumsparend beispielsweise so angeordnet sein, dass er mit dem LED-Modul 2 eine zur Hauptachse L senkrecht orientierte Ebene E durchsetzt. Beispielsweise kann sich der Kühlkörper 1 - mit Bezug auf die Hauptachse L - zumindest über einen Höhenbereich B erstrecken, der durch die wenigstens eine LED des LED-Moduls 2 festgelegt ist. Im gezeigten Beispiel erstreckt sich der Kühlkörper 1 über diesen Bereich B hinaus, und zwar sowohl auf derjenigen Seite, die zum Sockel 8 hin weist, als auch zur gegenüberliegenden Seite - mit Bezug auf Fig. 1 also nach oben und unten über den Bereich B hinaus. Der Kühlkörper 1 kann hierbei so gestaltet sein, dass er - normal zur Hauptachse L betrachtet - einen größeren Querschnitt aufweist als der Sockel 8. Im gezeigten Beispiel ist dies beispielsweise im Querschnitt des Kühlkörpers 1 auf Höhe der Ebene E der Fall. Dies ermöglicht einen vergleichsweise großen und damit besonders effektiven Kühlkörper 1.Preferably, the LED lamp further comprises a heat sink 1 for cooling the LED module 2. The heat sink 1 can be arranged to save space, for example, so that it interspersed with the LED module 2 a perpendicular to the main axis L oriented plane E. For example, the heat sink 1 - with respect to the main axis L - at least extend over a height range B , which is determined by the at least one LED of the LED module 2. In the example shown, the heat sink 1 extends beyond this region B , both on the side facing the base 8 and on the opposite side - with reference to FIG Fig. 1 So up and down over the area B addition. In this case, the heat sink 1 can be designed such that it-viewed normal to the main axis L -has a larger cross-section than the base 8. In the example shown, this is the case, for example, in the cross-section of the heat sink 1 at level E level. This allows a comparatively large and thus particularly effective heat sink 1.

Der Kühlkörper 1 kann in an sich bekannte Weise zur Vergrößerung der Kühlfläche Lamellen aufweisen.The heat sink 1 can have lamellas in a manner known per se for enlarging the cooling surface.

Der Kühlkörper 1 kann derart gestaltet sein, dass er einen Außenflächenbereich der LED-Lampe bildet. Auf diese Weise kann ein Oberflächenbereich des Kühlkörpers 1 als Grifffläche zur Handhabung der LED-Lampe dienen, also beispielsweise als Angriffsfläche beim Einschrauben der LED-Lampe in eine Fassung. Vorteilhaft weist dabei der genannte Oberflächenbereich eine elektrisch isolierte, beispielsweise nicht-metallische Oberfläche auf. Insbesondere kann der Kühlkörper 1 nach Sicherheitsstandards an anfassbaren Teilen durch nicht-metallische Oberflächen elektrisch isoliert sein.The heat sink 1 may be configured to form an outer surface area of the LED lamp. In this way, a surface region of the heat sink 1 can serve as a grip surface for handling the LED lamp, that is, for example, as a contact surface when screwing the LED lamp into a socket. Advantageously In this case, said surface area on an electrically insulated, for example, non-metallic surface. In particular, the heat sink 1 according to safety standards on touchable parts by non-metallic surfaces can be electrically isolated.

Vorzugsweise weist die LED-Lampe weiterhin eine Abdeckung 3 des LED-Moduls 2 auf, die zum Schutz und/oder als optisches Element dient. Die Abdeckung 3 kann insbesondere transparent oder lichtstreuend sein.Preferably, the LED lamp further comprises a cover 3 of the LED module 2, which serves for the protection and / or as an optical element. The cover 3 may in particular be transparent or light-scattering.

Vorzugsweise weist die LED-Lampe weiterhin ein Elektronik-Modul 4 zur elektrischen Versorgung der wenigstens einen LED des LED-Moduls 2 auf. Bei dem Elektronik-Modul 4 kann es sich beispielsweise um eine Konstantstromquelle handeln. Vorteilhaft ist das Elektronik-Modul 4 am Kühlkörper 1 angeordnet. Beispielsweise kann vorgesehen sein, dass das Elektronik-Modul 4 in direktem thermischem Kontakt mit dem Kühlkörper 1 angeordnet ist.Preferably, the LED lamp further comprises an electronic module 4 for the electrical supply of the at least one LED of the LED module 2. The electronics module 4 may be, for example, a constant current source. Advantageously, the electronics module 4 is arranged on the heat sink 1. For example, it can be provided that the electronics module 4 is arranged in direct thermal contact with the heat sink 1.

Zur Speisung des Elektronik-Moduls 4 kann vorteilhaft weiterhin ein weiteres Elektronik-Modul 5, beispielsweise in Form eines Konverters vorgesehen sein. Das weitere Elektronik-Modul 5 kann dabei insbesondere in raumsparend vorteilhafter Weise zwischen dem Kühlkörper 1 und dem Sockel 8 angeordnet sein, wie in Fig. 1 schematisch dargestellt. Das weitere Elektronik-Modul 5 kann dabei zur Herstellung einer Verbindung zwischen den beiden Polen des Sockels 8 über den wenigstens einen Schleifkontakt 7 vorgesehen sein.For feeding the electronic module 4 can advantageously continue to be provided another electronic module 5, for example in the form of a converter. The further electronic module 5 can be arranged in particular in a space-saving advantageous manner between the heat sink 1 and the base 8, as in Fig. 1 shown schematically. The further electronic module 5 can be provided for establishing a connection between the two poles of the base 8 via the at least one sliding contact 7.

Die LED-Lampe kann insgesamt so geformt sein, dass ihre äußere Oberfläche der Oberfläche einer herkömmlichen Glühlampe ähnlich ist. Sie kann beispielsweise als Ersatz für Glühlampen in haushaltsüblichen flachen Leuchten verwendet werden; besonders eignet sie sich als Ersatz für eine herkömmliche Glühlampe, wenn die entsprechende Leuchte so konstruiert ist, dass eine Lichtaustrittsfläche entsprechend seitlich von der Glühlampe vorgesehen ist.The LED lamp as a whole may be shaped so that its outer surface is similar to the surface of a conventional incandescent lamp. It can be used, for example, as a replacement for incandescent lamps in household flat lights; in particular, it is suitable as a replacement for a conventional incandescent lamp, if the corresponding lamp is designed so that a light exit surface is provided according to the side of the light bulb.
