Definitions

  • the invention relates to an LED lamp according to the preamble of claim 1.
  • LEDs Light-emitting diodes
  • the use of light-emitting diodes has hitherto been limited to certain fields of application, for example in signal technology, and has not yet been able to displace conventional light sources in the domestic sector.
  • the main problem here is that light emitting diodes are not very thermally stable.
  • the LEDs show a dependency of the operating temperature on the luminous flux as well as the service life. As a rule, with a temperature increase of about 50 degrees Celsius (starting from a value of 25 degrees Celsius), the radiant power of the LEDs decreases by approx. 15 percent and the service life increases less than half sinks.
  • the Utility Model DE 20 2007 008 258 U1 shows here a solution already technically offered solution in which connects to the lamp socket for the power connection of the bulb, a heat sink with a large surface in the form of a piston stub, on the upper flat end of a plate-shaped arrangement of LEDs, whereby the heat output generated by the LEDs directly can be absorbed by this heat sink.
  • This device is then completed by the addressed transparent hollow body, which is formed, for example, half-shell-shaped, whereby also this construction has a light bulb-shaped character in its basic form.
  • a fundamental problem of the light bulbs LED lamps presented on the market is in particular that they have a spot-like beam effect. That is, the light emission is not on all sides as in a known light bulb, but is due to the flat arrangement of the LED bulbs on a board and the arrangement relatively far forward in the bulb-shaped lamp body aligned strongly forward.
  • this LED replacement bulb expresses this structural peculiarity by the separation into a trained only as a hemisphere radiation ball and the base, which acts as a heat sink, so that a two-part impression is created, which does not match that of a conventional light bulb at the radiation emanates from the entire body.
  • these bulbs often have a larger design than ordinary light bulbs, since the design-related available cooling surface otherwise insufficient to achieve comparable brightness with light bulbs.
  • the problem of the radiation angle leads in these designs to the fact that the LED lights optically do not convey the feeling of a conventional light bulb.
  • the object of the present invention is therefore to provide an LED lamp according to the preamble of the main claim, which corresponds to the known light bulb shapes both in shape and size, as well as in their dispersion and in their light intensity allows a bulb-like illumination by the light source.
  • the core idea of the invention here was to achieve the bulb character of the bulb by the fact that the heat sink carrying and technically required heat sink itself dictates the shape of the bulb and the emission of the LEDs.
  • the heat sink may in this case be formed as a body or be composed of a plurality of separate heat sinks, which are assigned to the respective bulbs arranged around a central axis.
  • a transparent piston-like body enclosing the LEDs is completely dispensed with, as a result of which the shape of the LED light is determined exclusively by specifying the heat sink or the heat sink.
  • a transparent piston or half-piston modeled on the bulb shape is not a required part of the integral structure of the bulb and would merely have an ornamental character, for example in the form of a pop-up silicone coating with air holes completely surrounding the bulb from the thread.
  • the heat sink on LED bulbs which are arranged distributed over the outer surface of the piston-shaped heat sink, whereby the orientation of the radiation of these bulbs is determined by the bulb shape of the heat sink, thus achieving a uniform and almost all-sided light emission can be.
  • a plurality of heat sinks LED lighting means each with a sheathed heat sink, which arranged so are that a bulb similar contour arises, whereby the orientation of the radiation of these bulbs is determined by the overall piston-shaped arrangement of the heat sink and thus a uniform and almost all-round light emission can be achieved, as was also described in the first design.
  • the LEDs arranged on the heat sink are not flat and flat on a board, but that several LEDs or small groups of LEDs with low power LEDs evenly in or on the heat sink or the heat sinks along through the or the heatsink contoured bulb bulbs are distributed and thus follow its contour in their beam alignment.
  • This has in addition to the uniform emission of the LED lamp also has the advantage that the LEDs, which are often arranged side by side in known solutions, distribute in the invention on the or the heat sink and the projected from these piston surface, whereby they are not mutually exclusive heat up and thus the life and also the emission power of the LEDs are improved.
  • the invention makes it possible to use a single or a plurality of heat sinks assembled heat sink in maximum size, namely in the entire LED light. Compared to the solutions outlined above, it is possible in this way to raise the cooling surface of the entire LED light up to three times the value of the cooling surface that can be used by conventional solutions. Due to this technical starting situation, the problem of equipping such a light bulb with a brightness corresponding to the average brightness of known light bulbs is solved, since the central question of the cooling performance is solved. The replacement of a conventional 60-watt light bulb with a color temperature of 2900 Kelvin is thus realized in the current state of the art.
  • the invention allows according to the design formed of a plurality of heat sinks, each associated with at least one LED bulb that all modules are surrounded by ambient air, regardless of the angle of use of the lamp uniformly and thus optimum convection, ie heat dissipation of the individual modules to the ambient air, is guaranteed.
  • the heat is also emitted directly in the immediate vicinity of the LED. Therefore, no losses of cooling performance occur due to thermal resistance of the material along the heat transfer paths within the heat sink, e.g. from the top LED to the bottom of the LED light as in the first design.
  • the positive effect of these basic designs is that the efficiency of the LEDs is increased, the LEDs or the LED light can have very long lifetimes, the color rendering properties and thus a better quality of light can be achieved because the higher or optimized cooling capacity a larger feed of energy into the system, which can optionally be used for higher brightness and / or better color rendering and / or longer life and energy efficiency with lower energy input and thus generally colder system use, all these properties are supported by a uniform uniform light emission.
  • a currently realistic expedient design of this LED light can have, for example as technical values a brightness of about 710 lumens at a beam angle of about 340 degrees and a color temperature of 2900 Kelvin and a color rendering greater than Ra90, at the same time a common dimension of a piston diameter of about 55 mm with a total length (including E27 socket) of 97 mm. This is based on a conventional E27 socket with a power consumption of only 11 watts secondary side as a replacement for a conventional 60-watt bulb.
  • the radiated light is formed by 11 intersecting and superimposed radiating light units, which have a beam angle of about 130 degrees.
  • the individual light units used in the light bulb-shaped heat sink are formed in an advantageous embodiment of the invention as in approximately funnel-shaped body, which are used in recesses in the heat sink or are used anchored in a plurality of heat sinks on the LED driver module.
  • the approximately funnel-shaped lighting units can be formed by these heat sinks. These consist of a funnel-shaped outer heat-conducting aluminum jacket or copper jacket or ceramic jacket or a jacket a highly thermally conductive alloy or a highly thermally conductive composite material, in which a high-performance light-emitting diode on an aluminum or copper plate or ceramic board or a board made of a good heat-conducting alloy or a good heat-conducting composite material is applied and which is completed by a diffuser or a scattering lens.
  • a radiation angle of about 180 degrees is realized, whereby a closed uniform radiation is achieved, although the lamp is composed of a plurality of individual LEDs.
  • Another positive aspect of this arrangement is that the comparatively bright light of the individual lighting units, which emanates in an appropriate design only from a radiating surface of the LED chips of about 1 to 2 mm 2 , is distributed homogeneously over the scattering lens and thus the human Eye less directly on direct sight of the LED light.
  • the scattering lens or the diffuser cap is made of a plastic acrylate, in which diffuser beads are incorporated. In this way, it comes to the uniform deflection of the light emission and the aforementioned distribution of radiation in a wide angle of radiation.
  • a clear transparent medium may also be used as the termination. This increases efficiency, for example in applications where the lamp is placed behind a diffuser. However, then a universal applicability is not given and the light source is bound to its specific site and can not be used at will in various locations.
  • Another alternative is a tightly focused lens. This ensures that the individual lights spread like spots ('disco ball effect'), which of course would not correspond to the character of an ordinary light bulb.
  • Another alternative is an adjustable lens which, depending on the user-defined setting, spreads wide to narrowly focused to produce special user-dependent lighting scenes.
  • Such adjustment can be combined in a further advantageous alternative with the steering of the light in a certain direction, which deviates from the central axis of the light module.
  • the light cone emitted by the light modules can be bundled in such a way as, for example, to accentuate a part of the illuminated space, for example a space section which is to be illuminated particularly brightly.

  • the outer surfaces of the funnel-shaped body are thus pressed flush, for example by the Verschraubungsvorgang in the funnel-shaped receptacles of the heat sink.
  • This has the advantage that the heat exchange between funnel-shaped body and heat sink is optimized and can be largely dispensed with thermally conductive aids such as thermal compounds.

Description

Die Erfindung betrifft eine LED-Leuchte gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to an LED lamp according to the preamble of claim 1.

Leuchtdioden (LEDs) weisen im Vergleich zu bekannten Lichtquellen deutliche Vorzüge auf. Diese sind unter anderem eine höhere Lebensdauer und Zuverlässigkeit, insbesondere aber ein deutlich geringerer Energieverbrauch, wodurch die Effizienz dieser Lichtquellen gegenüber den herkömmlichen Lichtquellen erhöht ist. Allerdings ist bislang der Einsatz von Leuchtdioden auf bestimmte Anwendungsbereiche, beispielsweise in der Signaltechnik, beschränkt und hat noch nicht herkömmliche Leuchtmittel im häuslichen Bereich verdrängen können.Light-emitting diodes (LEDs) have clear advantages over known light sources. These include a longer life and reliability, but in particular a much lower energy consumption, whereby the efficiency of these light sources is increased over the conventional light sources. However, the use of light-emitting diodes has hitherto been limited to certain fields of application, for example in signal technology, and has not yet been able to displace conventional light sources in the domestic sector.

DieHauptproblematik hierbei ist, dass Leuchtdioden nicht stark thermisch belastbar sind. Die LEDs zeigen hierbei eine Abhängigkeit von der Betriebstemperatur zum Lichtstrom sowie der Lebensdauer, wodurch in der Regel bei einer Temperaturerhöhung um etwa 50 Grad Celsius (ausgehend von einem Wert von 25 Grad Celsius) die Strahlungsleistung der LEDs um etwa 15 Prozent abnimmt und die Lebensdauer auf weniger als die Hälfte absinkt.The main problem here is that light emitting diodes are not very thermally stable. The LEDs show a dependency of the operating temperature on the luminous flux as well as the service life. As a rule, with a temperature increase of about 50 degrees Celsius (starting from a value of 25 degrees Celsius), the radiant power of the LEDs decreases by approx. 15 percent and the service life increases less than half sinks.

Es ist daherbei der Ausgestaltung von LED-Leuchten darauf zu achten, dass eine kältere Umgebung die Effizienz und die Lebensdauer der LEDs verbessert. Der Wärmehaushalt eines LED-Leuchtmittels ist daher ein zentraler Entwicklungsfaktor, wobei insbesondere darauf zu achten ist, die Wärme kontrolliert von dem LED-Leuchteinheit abzuführen, um Wärmestaus zu vermeiden.It is therefore important in the design of LED lights to ensure that a colder environment improves the efficiency and lifetime of the LEDs. The heat balance of an LED light source is therefore a key development factor, with particular care should be taken to remove the heat controlled by the LED light unit to prevent heat build-up.

Neben diesen Bemühungen um die kontrollierte Wärmeabfuhr der LED-Leuchtmittel sind elektronische Komponenten nötig, da die LEDs nicht direkt über das Stromnetz betrieben werden können. Es ist daher ein deutlicher Entwicklungsaufwand erforderlich, um LEDs in dem Bereich der häuslichen Lichttechnik einführen zu können.In addition to these efforts for the controlled heat dissipation of the LED bulbs, electronic components are necessary because the LEDs can not be operated directly from the mains. It is therefore a significant development effort required to introduce LEDs in the field of home lighting technology can.

Es hat in den vergangenen Jahren einige Ansätze gegebenen, eine derartige Nutzung der LED-Technik im Bereich herkömmlicher Leuchtmittel voranzutreiben. Hierbei ist, wie bereits ausgeführt, die Frage der Wärmeabfuhr ein zentrales Anliegen. Gleichzeitig ist auffällig, dass im Bereich der häuslichen Lichttechnik das Bestreben da ist, dem Kunden orientiert an seine gewohnte Formgebung der Leuchtmittel, nämlich die der klassischen Glühbirne, ein Alternativprodukt anbieten zu können.There have been some attempts in recent years to promote such use of LED technology in the field of conventional bulbs. Here, as already stated, the issue of heat dissipation is a central concern. At the same time, it is noticeable that there is a desire in the field of home lighting technology to be able to offer the customer an alternative product to the usual shape of the light source, namely the classic light bulb.

Es wird hierbei in der Regel versucht, einen glühbirnenartigen Grundkörper beizubehalten, also einen Leuchtdiodenträger mit entsprechenden elektronisch erforderlichen Komponenten in einen geschlossenen kolbenförmigen Körper einzubetten. Derartige Offenbarung sind beispielsweise in der Schrift CN 201386989 Y , DE 10 2007037820 A1 , DE 20 2008 016 870 U1 , DE 10 2007 045 540 A1 , DE 20 2008 015 948 U1 , WO 2009/083853 A1 , WO 2009/074322 A1 , EP 2 077 414 A1 sowie DE 20 2005 017 767 U1 offenbart.In this case, it is usually attempted to maintain a bulb-like basic body, ie to embed a light-emitting diode carrier with corresponding electronically required components in a closed piston-shaped body. Such disclosure is for example in the Scriptures CN 201386989 Y . DE 10 2007037820 A1 . DE 20 2008 016 870 U1 . DE 10 2007 045 540 A1 . DE 20 2008 015 948 U1 . WO 2009/083853 A1 . WO 2009/074322 A1 . EP 2 077 414 A1 such as DE 20 2005 017 767 U1 disclosed.

Es handelt sich hierbei immer um zusammengesetzte Systeme, die einen Lampensockel zum Einschrauben in eine entsprechende Lampenfassung aufweisen, von dem ausgehend ein in etwa kolbenartig in Form bekannter Glühbirnen ausgebildeter und das eigentliche Leuchtmittel aufnehmender transparenter Hohlkörper anschließt, wobei dieser aus Glas, Kunststoff oder anderen lichtdurchlässigen Materialien aufgebaut ist.These are always composite systems that have a lamp base for screwing into a corresponding lamp socket, starting from which a trained in about piston-like bulbs in the form of known light bulbs and the actual bulbs receiving transparent hollow body connects, said glass, plastic or other translucent Materials is constructed.

Es finden sich hierbei verschiedene Offenbarungen, wie die Lichtquellen innerhalb dieses lichtdurchlässigen geschlossenen Körpers anzuordnen sind. Die Gebrauchsmusterschrift DE 20 2007 008 258 U1 zeigt hierbei ein auch bereits technisch angebotenes Lösungskonzept, bei dem an dem Lampensockel für den Stromanschluss des Leuchtmittels ein Kühlkörper mit großer Oberfläche in Form eine Kolbenstumpfes anschließt, auf dessen oberen flachen Ende eine plattenförmige Anordnung von LEDs aufsitzt, wodurch die von den LEDs erzeugte Wärmeabgabe direkt von diesem Kühlkörper aufgenommen werden kann. Abgeschlossen wird diese Vorrichtung dann von dem angesprochenen transparenten Hohlkörper, der beispielsweise halbschalenförmig ausgebildet ist, wodurch auch diese Konstruktion eine in ihrer Grundform glühbirnenförmigen Charakter aufweist.There are hereby various disclosures on how to arrange the light sources within this translucent closed body. The Utility Model DE 20 2007 008 258 U1 shows here a solution already technically offered solution in which connects to the lamp socket for the power connection of the bulb, a heat sink with a large surface in the form of a piston stub, on the upper flat end of a plate-shaped arrangement of LEDs, whereby the heat output generated by the LEDs directly can be absorbed by this heat sink. This device is then completed by the addressed transparent hollow body, which is formed, for example, half-shell-shaped, whereby also this construction has a light bulb-shaped character in its basic form.

Ein grundsätzliches Problem der am Markt vorgestellten glühbirnenförmigen LED-Leuchten ist insbesondere, dass diese einen spotartigen Strahleffekt aufweisen. Das heißt, die Lichtabstrahlung erfolgt nicht wie bei einer bekannten Glühbirne allseitig, sondern ist aufgrund der flächigen Anordnung der LED-Leuchtmittel auf einer Platine und der Anordnung relativ weit vorne im glühbirnenförmigen Lampenkörper stark nach vorne ausgerichtet.A fundamental problem of the light bulbs LED lamps presented on the market is in particular that they have a spot-like beam effect. That is, the light emission is not on all sides as in a known light bulb, but is due to the flat arrangement of the LED bulbs on a board and the arrangement relatively far forward in the bulb-shaped lamp body aligned strongly forward.

Auch im Gesamterscheinungsbild dieser Ersatzglühbirne auf LED-Basis drückt sich diese bauliche Eigenart aus durch die Trennung in eine lediglich als Halbkugel ausgebildete Strahlungskugel und die Basis, die als Kühlkörper fungiert, so daß ein zweigeteilter Eindruck entsteht, der nicht dem einer herkömmlichen Glühbirne entspricht, bei der die Abstrahlung von dem gesamten Körper ausgeht. Zudem weisen diese Birnen häufig eine größere Bauform auf als gewöhnliche Glühbirnen, da die bauartbedingt zur Verfügung stehende Kühlfläche ansonsten nicht ausreicht, um eine mit Glühbirnen vergleichbare Helligkeit zu erzielen.Also in the overall appearance of this LED replacement bulb expresses this structural peculiarity by the separation into a trained only as a hemisphere radiation ball and the base, which acts as a heat sink, so that a two-part impression is created, which does not match that of a conventional light bulb at the radiation emanates from the entire body. In addition, these bulbs often have a larger design than ordinary light bulbs, since the design-related available cooling surface otherwise insufficient to achieve comparable brightness with light bulbs.

Es ist grundsätzlich festzuhalten, dass eine ganze Reihe von Anbietern ähnliche, auf diesem technischen Aufbau basierende Modelle anbieten, die von einem Gewinde ausgehend eine etwa die Hälfte der Gesamtlänge desLeuchtmittels einnehmenden Kühlkörper aufweisen, wodurch lediglich die vordere Hälfte der LED-Leuchte als abstrahlender Bereich verwendet werden kann. Dies drückt sich zudem darin aus, dass diese Glühbirnen nicht die Lichtqualität aufweisen, wie dies die herkömmliche Glühbirne tut. Dies betrifft die Abstrahlung in alle Richtungen und die eigentlich Lichtleistung, die häufig bei einem geringen Wert liegt, als dieser von Hersteller angegeben ist und somit auch unter dem Wert liegt, den herkömmliche Glühbirnen aufweisen.It is to be noted in principle that a whole series of suppliers offer similar models based on this technical structure, which starting from a thread have a heat sink occupying approximately half the total length of the luminaire, whereby only the front half of the LED luminaire is used as the emitting area can be. This is also reflected in the fact that these bulbs do not have the quality of light, as does the conventional light bulb. This applies to the radiation in all directions and the actual light output, which is often at a low value, as it is specified by the manufacturer and thus also below the value that have conventional light bulbs.

Insbesondere die Problematik des Abstrahlwinkels führt bei diesen Bauformen dazu, dass die LED-Leuchten auch optisch nicht das Gefühl einer herkömmlichen Glühbirne vermitteln.In particular, the problem of the radiation angle leads in these designs to the fact that the LED lights optically do not convey the feeling of a conventional light bulb.

Die Aufgabe der vorliegenden Erfindung ist somit, eine LED-Leuchte nach dem Oberbegriff des Hauptanspruchs zu schaffen, die sowohl in Ihrer Kontur und Größe den bekannten Glühbirnenformen entspricht, als auch in ihrem Abstrahlverhalten und in ihrer Lichtstärke eine glühbirnenartige Ausleuchtung durch das Leuchtmittel ermöglicht.The object of the present invention is therefore to provide an LED lamp according to the preamble of the main claim, which corresponds to the known light bulb shapes both in shape and size, as well as in their dispersion and in their light intensity allows a bulb-like illumination by the light source.

Erreicht wird dies nach der Erfindung durch eine LED-Leuchte gemäß den Merkmalen des Anspruchs 1.This is achieved according to the invention by an LED lamp according to the features of claim 1.

Die Unteransprüche 2 bis 11 haben vorteilhafte Ausgestaltungen dieser Erfindung zum Gegenstand.The subclaims 2 to 11 relate to advantageous embodiments of this invention.

Kerngedanke der Erfindung war hierbei, den Glühbirnencharakter des Leuchtmittels dadurch zu erreichen, dass der die Leuchtmittel tragende und technisch erforderliche Kühlkörper selbst die Formgebung der Glühbirne sowie die Abstrahlung der LEDs vorgibt. Der Kühlkörper kann hierbei als ein Körper ausgebildet sein oder zusammengesetzt sein aus mehreren separate Kühlkörpern, die den jeweiligen Leuchtmitteln zugeordnet um eine zentrale Achse angeordnet sind.The core idea of the invention here was to achieve the bulb character of the bulb by the fact that the heat sink carrying and technically required heat sink itself dictates the shape of the bulb and the emission of the LEDs. The heat sink may in this case be formed as a body or be composed of a plurality of separate heat sinks, which are assigned to the respective bulbs arranged around a central axis.

Im Gegensatz zu den bereits bekannten und ausführlich beschriebenen Lösungen, bei denen beispielsweise vom Gewinde ausgehend etwa zwei Drittel des Lampenkörpers den Kühlkörper bilden, der ebenfalls bereits in seiner Formgebung einem Teil einer Glühbirne ähnelt, allerdings das vordere Drittel des Glühbirnenkörpers durch eine halbschalenförmige transparente Kuppel abschließt, die die eigentlichen Leuchtmittel einschließt und somit den Glaskolbencharakter einer Glühbirne aufnimmt, geht nun der Erfindungsgegenstand einen völlig neuen Weg.In contrast to the already known and described in detail solutions in which, for example, starting from the thread about two-thirds of the lamp body form the heat sink, which also resembles in its shape a part of a light bulb, but the front third of the bulb body terminates by a half-shell-shaped transparent dome , which includes the actual bulbs and thus absorbs the glass bulb character of a light bulb, now the subject of the invention goes a completely new way.

Es wird hierbei beim Erfindungsgegenstand auf einen die LEDs einschließenden transparenten kolbenartigen Körper vollständig verzichtet, wodurch die Formgebung der LED-Leuchte ausschließlich durch die Vorgabe des Kühlkörpers bzw. der Kühlkörper bestimmt ist. Ein transparenter, der Glühbirnenform nachempfundener Kolben oder Halbkolben ist kein erforderlicher Teil des integralen Aufbaus des Leuchtmittels und hätte lediglichdekorativen Charakter, beispielsweise in Form eines den Lampenkörper vom Gewinde ausgehend vollständig umschließenden, aufgestülpten Silikonüberzugs mit Luftlöchern.In this case, in the subject matter of the invention, a transparent piston-like body enclosing the LEDs is completely dispensed with, as a result of which the shape of the LED light is determined exclusively by specifying the heat sink or the heat sink. A transparent piston or half-piston modeled on the bulb shape is not a required part of the integral structure of the bulb and would merely have an ornamental character, for example in the form of a pop-up silicone coating with air holes completely surrounding the bulb from the thread.

Bei einer ersten Bauform der LED-Leuchte weist der Kühlkörper LED-Leuchtmittel auf, die über die Außenfläche des kolbenförmigen Kühlkörpers verteilt angeordnet sind, wodurch die Ausrichtung der Abstrahlung dieser Leuchtmittel durch die Kolbenform des Kühlkörpers vorgegeben wird und somit eine gleichmäßige und nahezu allseitige Lichtabstrahlung erreicht werden kann.In a first design of the LED lamp, the heat sink on LED bulbs, which are arranged distributed over the outer surface of the piston-shaped heat sink, whereby the orientation of the radiation of these bulbs is determined by the bulb shape of the heat sink, thus achieving a uniform and almost all-sided light emission can be.

In einer anderen vorteilhaften Bauform der Erfindung weisen mehrere Kühlkörper LED-Leuchtmittel mit jeweils einem ummantelten Kühlkörper auf, welche so angeordnet sind dass eine glühbirnenähnliche Kontur entsteht, wodurch die Ausrichtung der Abstrahlung dieser Leuchtmittel durch die im gesamten kolbenförmige Anordnung der Kühlkörper vorgegeben wird und somit eine gleichmäßige und nahezu allseitige Lichtabstrahlung erreicht werden kann, wie dies auch bei der ersten Bauform beschrieben wurde.In another advantageous embodiment of the invention, a plurality of heat sinks LED lighting means, each with a sheathed heat sink, which arranged so are that a bulb similar contour arises, whereby the orientation of the radiation of these bulbs is determined by the overall piston-shaped arrangement of the heat sink and thus a uniform and almost all-round light emission can be achieved, as was also described in the first design.

Es ist hierbei ein zentrales erfinderisches Merkmal, dass die am Kühlkörper angeordneten LEDs nicht eben und flächig auf einer Platine angeordnet sind, sondern dassmehrere LEDs oder kleine LED-Gruppen mit LEDs geringer Leistung gleichmäßig im bzw. am Kühlkörper bzw. den Kühlkörpern entlang dem durch die bzw. den Kühlkörper konturierten Glühbirnenkolbens verteilt angebracht werden und so dessen Kontur in ihrer Abstrahlausrichtung folgen. Dies hat neben der gleichmäßigen Abstrahlung der LED-Leuchte zudem den Vorteil, dass sich die LEDs, die bei bekannten Lösungen häufig nebeneinander angeordnet werden, in der Erfindung über den bzw. die Kühlkörper und die von diesen projizierte Kolbenfläche verteilen, wodurch sie sich nicht gegenseitig aufheizen und somit die Lebensdauer und auch die Abstrahlleistung der LEDs verbessert werden.It is here a central inventive feature that the LEDs arranged on the heat sink are not flat and flat on a board, but that several LEDs or small groups of LEDs with low power LEDs evenly in or on the heat sink or the heat sinks along through the or the heatsink contoured bulb bulbs are distributed and thus follow its contour in their beam alignment. This has in addition to the uniform emission of the LED lamp also has the advantage that the LEDs, which are often arranged side by side in known solutions, distribute in the invention on the or the heat sink and the projected from these piston surface, whereby they are not mutually exclusive heat up and thus the life and also the emission power of the LEDs are improved.

Zudem ermöglicht die Erfindung, einen einzelnen oder aus mehreren Kühlkörpern zusammengesetzten Kühlkörper in maximaler Größe, nämlich in der der gesamten LED-Leuchte, zu verwenden. Gegenüber den zuvor skizzierten Lösungen ist es auf diese Weise möglich, die Kühloberfläche der gesamten LED-Leuchte bis zum dreifachen Wert der Kühloberfläche anzuheben, die von herkömmlichen Lösungen verwendet werden kann. Aufgrund dieser technischen Ausgangssituation ist die Problematik, eine derartige Glühbirne mit einer Helligkeit entsprechend der durchschnittlichen Helligkeit bekannter Glühbirnen auszustatten gelöst, da die zentrale Frage der Kühlleistung gelöst ist. Der Ersatz einer herkömmlichen 60-Watt-Glühbirne mit einer Farbtemperatur von 2900 Kelvin ist beim derzeitigen Stand der Technik somit zu verwirklichen.In addition, the invention makes it possible to use a single or a plurality of heat sinks assembled heat sink in maximum size, namely in the entire LED light. Compared to the solutions outlined above, it is possible in this way to raise the cooling surface of the entire LED light up to three times the value of the cooling surface that can be used by conventional solutions. Due to this technical starting situation, the problem of equipping such a light bulb with a brightness corresponding to the average brightness of known light bulbs is solved, since the central question of the cooling performance is solved. The replacement of a conventional 60-watt light bulb with a color temperature of 2900 Kelvin is thus realized in the current state of the art.

Zudem ermöglicht die Erfindung entsprechend der Bauform gebildet aus mehreren Kühlkörpern, denen jeweils zumindest ein LED-Leuchtmittel zugeordnet ist, dass alle Module unabhängig vom Einsatzwinkel der Lampe gleichmäßig von Umgebungsluft umströmt werden und somit eine optimale Konvektion, also Wärmeabgabe der einzelnen Module an die Umgebungsluft, gewährleistet ist. Die Wärme wird hierbei auch direkt im unmittelbaren Umfeld der LED abgegeben. Daher treten keine Verluste der Kühlleistung durch Wärmewiederstand des Materials entlang der Übertragungswege der Wärme innerhalb des Kühlkörpers auf, also z.B. von oberster LED an den unteren Rand der LED-Leuchte, wie bei der ersten Bauform.In addition, the invention allows according to the design formed of a plurality of heat sinks, each associated with at least one LED bulb that all modules are surrounded by ambient air, regardless of the angle of use of the lamp uniformly and thus optimum convection, ie heat dissipation of the individual modules to the ambient air, is guaranteed. The heat is also emitted directly in the immediate vicinity of the LED. Therefore, no losses of cooling performance occur due to thermal resistance of the material along the heat transfer paths within the heat sink, e.g. from the top LED to the bottom of the LED light as in the first design.

Durch diese direkte Wärmeabgabe kann der Kühlkörperanteil der Leuchte weiter reduziert werden, da die Kühlung hiermit optimiert wird. Dies hat auch Vorteile gegenüber Bauform 1 bezüglich der Herstellungskosten, da nicht mehr ein 'tragender' Kühlkörper mehr gebraucht wird, welcher relativ kompliziert aufgebaut ist und damit kostenintensiv hergestellt werden müsste. Schließlich ermöglicht diese Bauform die Montage bzw. Wartung des Leuchtmittels, wenn diese als Leuchte in modularer Bauform betrachtet wird, bei der die einzelnen Kühlkörper mit den LED-Leuchtmitteln bei Bedarf ausgetauscht werden können.Through this direct heat dissipation of the heat sink component of the lamp can be further reduced because the cooling is hereby optimized. This also has advantages over design 1 in terms of manufacturing costs, since no longer a 'supporting' heat sink is needed, which is constructed relatively complicated and thus would have to be produced cost-intensive. Finally, this design allows the installation or maintenance of the bulb when it is considered as a luminaire in a modular design, in which the individual heat sink can be replaced with the LED bulbs when needed.

Der positive Effekt dieser Grundkonstruktionen ist, dass die Effizienz der LEDs gesteigert wird, die LEDs bzw. die LED-Leuchte sehr lange Standzeiten aufweisen kann, die Farbwiedergabeeigenschaften und somit eine bessere Lichtqualität erzielt werden kann, da die höhere bzw. optimierte Kühlleistung eine größeren Einspeisung von Energie in das System zulässt, welche wahlweise für höhere Helligkeit und/oder bessere Farbwiedergabe und/oder längere Lebensdauer und Energieeffizienz bei geringerer Energieeinspeisung und damit allgemein kälterem System Verwendung finden kann, wobei all diese Eigenschaften unterstützt werden durch eine allseitig gleichmäßige Lichtabstrahlung.The positive effect of these basic designs is that the efficiency of the LEDs is increased, the LEDs or the LED light can have very long lifetimes, the color rendering properties and thus a better quality of light can be achieved because the higher or optimized cooling capacity a larger feed of energy into the system, which can optionally be used for higher brightness and / or better color rendering and / or longer life and energy efficiency with lower energy input and thus generally colder system use, all these properties are supported by a uniform uniform light emission.

Eine momentan realistische zweckmäßige Bauform dieser LED-Leuchte kann beispielsweise als technische Werte eine Helligkeit von ca. 710 Lumen bei einem Abstrahlwinkel von ca. 340 Grad und einer Farbtemperatur von 2900 Kelvinsowie eine Farbwiedergabe von größer als Ra90 aufweisen, gleichzeitig eine übliche Abmessung von einem Kolbendurchmesser von etwa 55 mm bei einer Gesamtlänge (incl. E27-Fassung) von 97 mm aufweisen. Dies ist aufgesetzt auf eine herkömmliche E27-Fassung bei einem Stromverbrauch von lediglich sekundärseitig 11 Watt als Ersatz für eine herkömmliche 60-Watt-Glühbirne.A currently realistic expedient design of this LED light can have, for example as technical values a brightness of about 710 lumens at a beam angle of about 340 degrees and a color temperature of 2900 Kelvin and a color rendering greater than Ra90, at the same time a common dimension of a piston diameter of about 55 mm with a total length (including E27 socket) of 97 mm. This is based on a conventional E27 socket with a power consumption of only 11 watts secondary side as a replacement for a conventional 60-watt bulb.

In einer vorteilhaften Ausgestaltung der erfindungsgemäßen LED-Leuchte wird das abgestrahlte Licht von 11 sich schneidenden und überlagert abstrahlenden Leuchteinheiten gebildet, wobei diese einen Abstrahlwinkel von etwa 130 Grad aufweisen. Dies sind allerdings lediglich Werte, die eine bauliche Realisation der LED-Leuchte zum momentanen Zeitpunkt betreffen. Es können sowohl Leuchten mit weniger, insbesondere aber Leuchten mit deutlich mehr Leuchteinheiten gebaut werden, was zu einer Reduzierung der Leistung der einzelnen Leuchteinheiten führt und insbesondere optische Unterschiede bewirkt, ohne den Kerngedanken der Erfindung zu verlassen. Es ist hierbei zweckmäßigerweise vorgesehen, den Leuchteinheiten einen Diffusor voranzusetzen, wodurch ein gleichmäßig gestreutes Abstrahlen des Lichtes erfolgt. Diese Diffusorkappe wirkt in diesem Fall als Streulinse.In an advantageous embodiment of the LED lamp according to the invention, the radiated light is formed by 11 intersecting and superimposed radiating light units, which have a beam angle of about 130 degrees. However, these are merely values that relate to a structural realization of the LED light at the moment. It can both lights with less, but especially lights are built with significantly more lighting units, which leads to a reduction in the performance of the individual lighting units and in particular causes visual differences, without departing from the essence of the invention. It is expediently provided to precede the light units with a diffuser, whereby a uniformly scattered radiation of the light takes place. This diffuser cap acts in this case as a scattering lens.

Die einzelnen in den glühbirnenförmigen Kühlkörper eingesetzten Leuchteinheiten sind in einer vorteilhaften Ausgestaltung der Erfindung als in etwa trichterförmige Körper ausgebildet, die in Aussparungen in den Kühlkörper eingesetzt werden oder eingesetzt in mehrere Kühlkörper am LED-Treibermodul verankert sind. Die in etwa trichterförmigen Leuchteinheiten können hierbei von diesen Kühlkörpern gebildet werden. Diese bestehen hierbei aus einem trichterförmigen äußeren wärmeleitenden Aluminiummantel oder Kupfermantel oder Keramikmantel bzw. einem Mantel aus einer gut wärmeleitenden Legierung oder einem gut wärmeleitenden Verbundmaterial, in dem eine Hochleistungsleuchtdiode auf einer Aluminiumplatine oder Kupferplatine oder Keramikplatine bzw. einer Platine aus einer gut wärmeleitenden Legierung oder einem gut wärmeleitenden Verbundmaterial aufgebracht ist und der von einem Diffusor bzw. einer Streulinse abgeschlossen wird.The individual light units used in the light bulb-shaped heat sink are formed in an advantageous embodiment of the invention as in approximately funnel-shaped body, which are used in recesses in the heat sink or are used anchored in a plurality of heat sinks on the LED driver module. The approximately funnel-shaped lighting units can be formed by these heat sinks. These consist of a funnel-shaped outer heat-conducting aluminum jacket or copper jacket or ceramic jacket or a jacket a highly thermally conductive alloy or a highly thermally conductive composite material, in which a high-performance light-emitting diode on an aluminum or copper plate or ceramic board or a board made of a good heat-conducting alloy or a good heat-conducting composite material is applied and which is completed by a diffuser or a scattering lens.

Durch diese Maßnahme wird ein Abstrahlwinkel von etwa 180 Grad realisiert, wodurch eine geschlossen gleichmäßige Abstrahlung erreicht wird, wenngleich die Leuchte aus einer Vielzahl einzelner LEDs zusammengesetzt ist. Ein weiterer positiver Aspekt dieser Anordnung ist, dass das vergleichsweise helle Licht der einzelnen Leuchteinheiten, welches in einer zweckmäßigen Bauform lediglich von einer Abstrahlfläche der LED-Chips von ca. 1 bis 2 mm2 ausgeht, über die Streulinse homogen verteilt wird und somit das menschliche Auge bei direktem Anblick der LED-Leuchte weniger blendet.By this measure, a radiation angle of about 180 degrees is realized, whereby a closed uniform radiation is achieved, although the lamp is composed of a plurality of individual LEDs. Another positive aspect of this arrangement is that the comparatively bright light of the individual lighting units, which emanates in an appropriate design only from a radiating surface of the LED chips of about 1 to 2 mm 2 , is distributed homogeneously over the scattering lens and thus the human Eye less directly on direct sight of the LED light.

In einer zweckmäßigen Ausführungsform der Erfindung ist die Streulinse bzw. die Diffusorkappe aus einem Kunststoff-Acrylat gefertigt, in welches Diffusorperlen eingearbeitet sind. Auf diese Weise kommt es zur gleichmäßigen Umlenkung der Lichtabstrahlung und zur angesprochenen Verteilung der Strahlung in einem weiten Abstrahlwinkel.In an advantageous embodiment of the invention, the scattering lens or the diffuser cap is made of a plastic acrylate, in which diffuser beads are incorporated. In this way, it comes to the uniform deflection of the light emission and the aforementioned distribution of radiation in a wide angle of radiation.

Alternativ kann anstelle eines Diffusors auch ein klares transparentes Medium als Abschluss verwendet werden. Dies steigert die Effizienz, zum Beispiel für Anwendungsgebiete bei denen die Lampe hinter einem Diffusor angeordnet wird. Allerdings ist dann eine universelle Einsetzbarkeit nicht gegeben und das Leuchtmittel ist an seinen spezifischen Einsatzort gebunden und kann nicht nach Belieben in verschiedenen Einsatzorten eingesetzt werden.Alternatively, instead of a diffuser, a clear transparent medium may also be used as the termination. This increases efficiency, for example in applications where the lamp is placed behind a diffuser. However, then a universal applicability is not given and the light source is bound to its specific site and can not be used at will in various locations.

Eine weitere Alternative ist eine eng bündelnde Linse. Hierdurch wird erreicht, dass sich die einzelnen Lichter spotähnlich ausbreiten ('Discokugeleffekt'), was aber selbstverständlich nicht dem Charakter einer gewöhnlichen Glühbirne entspräche.Another alternative is a tightly focused lens. This ensures that the individual lights spread like spots ('disco ball effect'), which of course would not correspond to the character of an ordinary light bulb.

Eine weitere Alternative ist eine verstellbare Linse, welche je nach benutzerdefinierter Einstellung breit streut bis eng fokussiert, um spezielle anwenderabhängige Lichtstimmungen zu erzeugen.Another alternative is an adjustable lens which, depending on the user-defined setting, spreads wide to narrowly focused to produce special user-dependent lighting scenes.

Eine solche Einstellmöglichkeit kann in einer weiteren vorteilhaften Alternative kombiniert werden mit der Lenkung des Lichtes in eine bestimmte Richtung, welche von der Mittelachse des Lichtmoduls abweicht. Die von den Lichtmodulen abgestrahlten Lichtkegel kann so gebündelt werden, um beispielsweise einen Teil des beleuchteten Raumes zu akzentuieren, beispielsweise ein Raumabschnitt welcher besonders hell ausgeleuchtet werden soll. Dies kann über Funksignale oder durch überlagerte Signale in der Speisespannung oder manuell gesteuert bzw. eingestellt werden.Such adjustment can be combined in a further advantageous alternative with the steering of the light in a certain direction, which deviates from the central axis of the light module. The light cone emitted by the light modules can be bundled in such a way as, for example, to accentuate a part of the illuminated space, for example a space section which is to be illuminated particularly brightly. This can be controlled via radio signals or by superimposed signals in the supply voltage or manually.

Zweckmäßigerweise ist im Innern des trichterförmigen Körpers, in welchem sich die LED-Platine befindet, die Innenwand schräg ausgeformt sodass seitlich aus der LED-Kuppel bzw. LED austretendes Licht von diesen schrägen Flächen nach vorne reflektiert wird, mit dem Ziel die aus dem trichterförmigen Körper austretende Lichtleistung zu steigern. Die inneren schrägen Flächen sind also Reflektoren. Zweckmäßigerweise sind diese Flächen mit einer reflektierenden Oberfläche bzw. Schicht versehen, wie beispielsweise Nickel oder Chrom oder poliertes Aluminium oder mit einer reflektierenden Lackierung.Conveniently, in the interior of the funnel-shaped body in which the LED board is located, the inner wall is formed obliquely so laterally from the LED dome or LED light emerging from these oblique surfaces is reflected forward, with the aim of increasing the light output exiting the funnel-shaped body. The inner oblique surfaces are therefore reflectors. Conveniently, these surfaces are provided with a reflective surface or layer, such as nickel or chromium or polished aluminum or with a reflective coating.

Zweckmäßigerweise sind die LED-Platinen, welche die LEDs Tragen und eine runde Kontur aufweisen, seitlich mit einem Außengewinde versehen, und werden mittels dieses Gewindes mit einem Innengewinde im trichterförmigen Körper verbunden.Conveniently, the LED boards, which carry the LEDs and have a round contour, laterally provided with an external thread, and are connected by means of this thread with an internal thread in the funnel-shaped body.

Zweckmäßigerweise wird zur besseren Wärmeübertragung zwischen LED-Platine und trichterförmigen Körper auf die Verbindungsflächen zwischen diesen beiden Körpern eine Wärmeleitpaste oder ein Wärmeleitklebeband angebracht um den Wärmeaustausch zwischen der LED-Platine und dem trichterförmigen Körpern zu optimieren. Dieser Wärmeaustausch wird durch die Kraftübertragung der Verbindungsgewinde auf die Stoßflächen noch optimiert.Conveniently, for better heat transfer between LED board and funnel-shaped body on the connecting surfaces between these two bodies, a thermal paste or a Wärmeleitklebeband attached to optimize the heat exchange between the LED board and the funnel-shaped bodies. This heat exchange is further optimized by the force transmission of the connecting threads on the abutment surfaces.

Bei der ersten Bauform ist zweckmäßigerweise an einem zylindrischen Stumpf der trichterförmigen Körper der Leuchteinheiten ein Gewinde, ein Bajonettverschluss oder eine andere mechanische kraft- und/oder formschlüssige Verbindung angebracht, mithilfe derer die trichterförmigen Körper mit dem Kühlkörper verbunden werden.In the first design, a thread, a bayonet lock or another mechanical positive and / or positive connection is expediently attached to a cylindrical stump of the funnel-shaped body of the light units, by means of which the funnel-shaped body are connected to the heat sink.

Die Trichterform der Körper ist hier vorteilig, da beim Einsetzen der trichterförmigen Körper in die trichterförmigen Aussparungen des Kühlkörpers ein Andruck zwischen den Innenflächen der trichterförmigen Aufnahmen des Kühlkörpers und den Außenflächen der trichterförmigen Körper entsteht, der der Wärmeübertragung dient. Die äußeren Flächen der trichterförmigen Körper werden also beispielsweise durch den Verschraubungsvorgang in die trichterförmigen Aufnahmen des Kühlkörpers flächenbündig angepresst. Dies hat den Vorteil dass der Wärmeaustausch zwischen trichterförmigem Körper und Kühlkörper optimiert wird und auf thermisch leitende Hilfsmittel wie Wärmeleitpasten weitestgehend verzichtet werden kann. Der optimierte Wärmeaustausch zwischen den einzelnen Elementen hat zur Folge dass das ganze System insgesamt eine bessere Kühlleistung erzielt, und die LEDs somit insgesamt kühler und somit Effizienter und langlebiger sind.The funnel shape of the body is advantageous here, since when inserting the funnel-shaped body in the funnel-shaped recesses of the heat sink, a pressure between the inner surfaces of the funnel-shaped receptacles of the heat sink and the outer surfaces of the funnel-shaped body is formed, which serves for heat transfer. The outer surfaces of the funnel-shaped body are thus pressed flush, for example by the Verschraubungsvorgang in the funnel-shaped receptacles of the heat sink. This has the advantage that the heat exchange between funnel-shaped body and heat sink is optimized and can be largely dispensed with thermally conductive aids such as thermal compounds. The optimized heat exchange between the individual elements means that the whole system achieves a better cooling performance overall, and the LEDs are thus cooler overall and therefore more efficient and durable.

Eine weitere zweckmäßige Ausgestaltung in Bezug auf Bauform 2 ist die Verbindung der trichterförmigen selbstkühlenden LED-Module(umfassend den Kühlkörper und die LED-Lichteinheitsowie Streulinse)mit dem LED-Treibermodul mittels vom Benutzer lösbaren Verbindungsschnittstellen, welche außer der Befestigung der Module an den Träger bzw. das LED-Treibermodul die Aufgabe haben, den Strom zu übertragen. Dies könnten beispielsweise sogenannte Klinkenstecker oder Cinchstecker sein, wie sie aus der Unterhaltungsindustrie bekannt sind.A further expedient embodiment with respect to design 2 is the connection of the funnel-shaped self-cooling LED modules (comprising the heat sink and the LED light unit and scattering lens) with the LED driver module by means of user-detachable connection interfaces, which except the attachment of the modules to the carrier or The LED driver module has the task of transmitting the power. These could be, for example, so-called jack plugs or RCA plugs, as they are known from the entertainment industry.

Die Vorteile die solch ein modularer, vom Benutzer lösbarer Aufbau bietet, wäre etwa die Möglichkeit verschiedenfarbige LED-Module einzusetzen, um bestimmte Lichtstimmungen zu erzeugen, oder aber die LED-Module unregelmäßig auf dem Trägermodul bzw. LED-Treibermodul zu platzieren, etwa um bestimmte Raumabschnitte des beleuchteten Raumes von der Beleuchtung auszulassen um bestimmte Lichtstimmungen zu erzeugen, oder aber einsatzbedingt die Energieersparnis zu erhöhen, wenn beispielsweise der Einsatzort derart gestaltet ist das es keinen Sinn macht in alle Richtungen abzustrahlen, und z.B. nur Licht nach vorne oder zur Seite gewünscht bzw. sinnvoll ist.The advantages offered by such a modular, user-detachable structure would be about the possibility to use different colored LED modules to produce certain lighting moods, or to place the LED modules irregularly on the carrier module or LED driver module, such as to omit certain sections of space of the illuminated space of the lighting to produce certain lighting moods, or to increase the energy savings due to use, for example, if the site is designed in such a way that it makes no sense to radiate in all directions, and eg only light forward or to the side desired or useful.

Zweckmäßigerweise ist im Innern des Kühlkörpers der LED-Leuchte bzw. zentral zwischen der Vielzahlvon Kühlkörpernein LED-Treiber angeordnet, wobei die elektromagnetische Abstrahlung, die durch einen derartigen LED-Treiber entstehen kann über den diesen umschließenden Kühlkörper absorbiert wird, dass heißt, der Kühlkörper hat neben der Funktion der Kühlung zudem den einer elektromagnetischen Abschirmung im Bezug auf die elektronische Komponente des LED-Treibers, der für die Umwandlung des Stroms bzw. die Umsetzung evtl. Dimm- oder Steuersignale erforderlich ist.Expediently, an LED driver is arranged inside the heat sink of the LED luminaire or centrally between the multiplicity of heat sinks, the electromagnetic radiation that can be produced by such an LED driver being absorbed via the heat sink enclosing it, that is to say the heat sink In addition to the function of cooling also an electromagnetic shield with respect to the electronic component of the LED driver, which is required for the conversion of the current or the implementation of any dimming or control signals.

Nachfolgend soll die Erfindung anhand von Zeichnungen näher beschrieben werden.The invention will be described in more detail with reference to drawings.

In Figur 1 ist die seitliche Ansicht der LED-Leuchte 1 im Gesamten dargestellt. Es wird hierbei deutlich, dass die einzelnen Leuchteinheiten 4 in den glühbirnenförmigen Gesamtkühlkörper 3 eingebettet sind. Dieser Kühlkörper 3 ist in der beispielhaften Ausführungsform gebildet aus von der Fassung 2 ausgehenden und in der vorderen Spitze der LED-Leuchte zusammen laufenden Lamellen 8, die von einem in etwa zylindrischen durchgängigen Kern 11 der LED-Leuchte ausgeht.In FIG. 1 the side view of the LED light 1 is shown as a whole. It is clear here that the individual light units 4 are embedded in the light bulb-shaped overall heat sink 3. This heat sink 3 is formed in the exemplary embodiment of outgoing from the socket 2 and in the front tip of the LED lamp together running lamellae 8, which emanates from an approximately cylindrical continuous core 11 of the LED lamp.

Zwischen diesen Lamellen 8 sind nun die einzelnen Leuchteinheiten 4 der LED-Leuchte 1 angeordnet, wobei eine Leuchteinheit 4 zentral nach vorne weist und an der Spitze der LED-Leuchte 1 angeordnet ist. Die weiteren Leuchteinheiten 4 sind in zwei ringförmigen Anordnungen von jeweils 5 Leuchteinheiten 4 gleichmäßig über den Umfang der LED-Leuchte 1 verteilt angeordnet, wobei die Abstände bei dem der Fassung am nächsten liegenden unteren Ring von Leuchteinheiten 4 zwischen den Leuchteinheiten 4 größer sind als bei dem näher zur vorderen Spitze der LED-Leuchte 1 gelegenen Ring.Between these slats 8, the individual light units 4 of the LED light 1 are now arranged, wherein a light unit 4 points centrally forward and is located at the top of the LED light 1. The further lighting units 4 are arranged distributed in two annular arrangements of 5 lighting units 4 evenly over the circumference of the LED lamp 1, wherein the distances at the socket closest to the lower ring of light units 4 between the light units 4 are larger than in the closer to the front tip of the LED lamp 1 ring.

Die Leuchteinheiten 4 selbst sind als in etwa trichterförmige Körper erkennbar, die von einer Streulinse 5 abgeschlossen sind, die auch als Diffusorkappe 5 wirkt. Diese liegen hierbei in der Ebene des glühbirnenförmigen Kühlkörpers 3 selbst und stehen somit nicht über die Grundform der LED-Leuchte 1 hinaus.The light units 4 themselves can be seen as approximately funnel-shaped body, which are completed by a scattering lens 5, which also acts as a diffuser cap 5. These lie here in the plane of the bulb-shaped heat sink 3 itself and thus are not beyond the basic shape of the LED light 1 addition.

In Figur 2 wird deutlich, wie die LED-Leuchte 1 aufgebaut ist. Sie besteht zum einen aus der Fassung 2 , auf der auf einem zylinderförmigen Fortsatz 11 der LED-Treiber 10 aufgesetzt ist. Auf diesen zylindrischen Fortsatz 11 ist der eigentliche Kühlkörper 3 mit den radial nach außen gerichteten Kühllamellen 8 aufgesetzt, wobei über den Kühlkörper 3 verteilt trichterförmige Aussparungen 9 vorgesehen sind, in die die Leuchteinheiten 4 einsetzbar sind.In FIG. 2 it becomes clear how the LED light 1 is constructed. It consists on the one hand of the version 2, on which on a cylindrical extension 11 of the LED driver 10 is placed. On this cylindrical extension 11 of the actual heat sink 3 is placed with the radially outwardly directed cooling fins 8, wherein distributed over the heat sink 3 funnel-shaped recesses 9 are provided, in which the light units 4 can be used.

Diese Leuchteinheiten 4 bestehen aus einem ebenfalls trichterförmigen Außenmantel 7, in dem eine Hochleistungs-LED 12 auf einer Trägerplatine 15 angeordnet ist und der von einer Streulinse bzw. Diffusorkappe 5 abgeschlossen ist. Die bauliche Einheit der Leuchteinheit 4 wird nun formschlüssig in den Kühlkörper 3 eingesetzt, wobei grundsätzlich verschiedene Möglichkeiten der Befestigung vorgesehen sein können, beispielsweise kraftschlüssige Verbindungen, Schraubverbindungen oder Klebverbindungen. Nach Einsetzen der Leuchteinheiten 4 in den Kühlkörper 3 sind diese mit den Streulinsen 5 flächig an der Kontur des Kühlkörpers anliegend, wodurch die angestrebte Glühbirnenform der LED-Leuchte 1 realisiert werden kann.These lighting units 4 consist of a likewise funnel-shaped outer jacket 7 in which a high-power LED 12 is arranged on a carrier board 15 and which is terminated by a diffuser cap or diffuser cap 5. The structural unit of the lighting unit 4 is now positively inserted into the heat sink 3, with fundamentally different possibilities of attachment can be provided, for example, non-positive connections, screw or adhesive joints. After insertion of the light units 4 in the heat sink 3, these are flat with the scattering lenses 5 on the contour of the heat sink, whereby the desired light bulb shape of the LED light 1 can be realized.

In Figur 3 ist ein horizontaler Schnitt oberhalb des LED-Treibers 10 durch die LED-Glühbirne 1 dargestellt. Es ist hierbei der Schnitt durch die unterste umlaufende Reihe von Leuchteinheiten 4 geführt, sodass man die trichterförmigen Außenmäntel 7 dieser Leuchteinheiten 4 geschnitten sieht sowie die in diese eingesetzten LEDs 12 auf den Trägerplatinen 15. Abgeschlossen werden diese durch die ebenfalls im Schnitt erkennbaren Diffusorkappen 5.In FIG. 3 For example, a horizontal section above the LED driver 10 is shown by the LED light bulb 1. It is the section through the lowest circulating Series of light units 4 out, so that one sees the funnel-shaped outer shells 7 cut these light units 4 and the LEDs used in these 12 on the support plates 15. These are completed by the also recognizable in section diffuser caps. 5

Es ist erkennbar, dass die Leuchteinheiten 4 radial von der Längsachse der LED-Leuchte ausgehend gleichmäßig verteilt ausgerichtet sind, wobei zwischen den Leuchteinheiten 4 deutliche Abstände erkennbar sind, in denen Lamellen des Kühlkörpers 3 verlaufen. Es ist hieraus ersichtlich, dass die einzelnen Leuchteinheiten 4 eine gute Wärmeableitung über die an diesen anliegenden Kühllamellen 8 aufweisen sowie durch den Abstand der Leuchteinheiten zueinander eine Wärmeübertragung unterbunden wird.It can be seen that the lighting units 4 are oriented radially distributed uniformly starting from the longitudinal axis of the LED light, wherein between the light units 4 clear distances can be seen, in which run lamellae of the heat sink 3. It can be seen from this that the individual lighting units 4 have good heat dissipation via the cooling fins 8 resting against them and heat transfer is prevented by the spacing of the lighting units from one another.

In Figur 4 wiederum ist ein vertikaler Schnitt durch eine aufrecht stehende LED-Leuchte 1 dargestellt, wobei hier insbesondere erkennbar ist, dass nicht nur radial zur Längsachse der LED-Leuchte 1 eine gleichmäßige Abstrahlanordnung 13 der Leuchteinheiten 4 vorgesehen ist, sondern dass auch die Verteilung der Leuchteinheiten 4 über die vertikal durch die LED-Leuchte 1 verlaufende Schnittebene gleichmäßig erfolgt. So ist die erste Leuchteinheit 4 an der Spitze der LED-Leuchte 1 angeordnet und die weiteren zwei Reihen in einem in etwa gleich bleibenden Winkeln zu dieser frontalen ersten Leuchteinheit 4 ausgehend vom zentralen Schnittpunkt im Kern der LED-Leuchte ausgehend ausgerichtet. Auf diese Weise erreicht die erfindungsgemäße LED-Leuchte 1 eine gleichmäßige Lichtabstrahlung 13 in Verbindung mit den verwendeten Diffusorkappen 5 und der Oberflächenbeschaffenheit des Kühlkörpers 3 selbst.In FIG. 4 in turn, a vertical section through an upright LED lamp 1 is shown, in which case it can be seen in particular that not only radially to the longitudinal axis of the LED lamp 1, a uniform Abstrahlanordnung 13 of the light units 4 is provided, but that the distribution of light units. 4 is uniform over the vertically extending through the LED light 1 cutting plane. Thus, the first lighting unit 4 is arranged at the top of the LED lamp 1 and the other two rows oriented in an approximately constant angles to this frontal first lighting unit 4, starting from the central intersection in the core of the LED light starting. In this way, the LED lamp 1 according to the invention achieves a uniform light emission 13 in conjunction with the diffuser caps 5 used and the surface quality of the heat sink 3 itself.

In den Figuren 5 und 6 sind die Leuchteinheiten 4 in genauer Darstellung erkennbar. Figur 5 zeigt hierbei eine Explosionszeichnung in perspektivischer Darstellung, wobei erkennbar ist, dass die trichterförmigen Außenmäntel 7 der Leuchteinheiten 4 über eine an ihrer Oberseite umlaufende Nut 14 zur Aufnahme der Diffusorkappe bzw. Streulinse 5 verfügen.In the FIGS. 5 and 6 the lighting units 4 can be seen in detail. FIG. 5 In this case, an exploded view in a perspective view, wherein it can be seen that the funnel-shaped outer shells 7 of the lighting units 4 have a circumferential groove 14 on its upper side for receiving the diffuser cap or scattering lens 5.

Die Platine 15 zur Aufnahme der LED 12 weist seitliche Rillen auf, um die Verkabelung der LEDs 12 zu ermöglichen. Die die LEDs 12 aufnehmenden Außenmäntel 7 weisen hierbei, wie in Figur 6 dargestellt eine zylindrische Bohrung 16 auf, um den Anschluss an den LED-Treiber 10 im Kern der LED-Leuchte 1 zu ermöglichen.The board 15 for receiving the LED 12 has lateral grooves to allow the wiring of the LEDs 12. The LEDs 12 receiving outer shells 7 in this case have, as in FIG. 6 12 illustrates a cylindrical bore 16 to facilitate connection to the LED driver 10 in the core of the LED lamp 1.

Figur 6 zeigt des weiteren, welche Wirkung die vorgesetzte Diffusorkappe 5 im Bezug auf die Streuung und die gleichmäßige Verteilung der Lichtabstrahlung aufweist. Es ist erkennbar, dass hier eine starke Streuung erfolgt, sodass der Eindruck der einzelnen Leuchteinheiten nicht mehr blendend ist. FIG. 6 further shows what effect the superior diffuser cap 5 with respect to the scattering and the uniform distribution of light emission. It can be seen that a strong scattering occurs here, so that the impression of the individual lighting units is no longer dazzling.

Figur 7 stellt eine seitliche Gesamtansicht einer weiteren Bauform der LED-Leuchte 1 mit mehreren Kühlkörpern 3 dar, die jeweils eine Leuchteinheit 4 tragen. Die Kühlkörper 3 sind hierbei ebenfalls trichterförmig ausgebildet und orientiert an der Kontur einer handelsüblichen Glühbirnen konzentrisch angeordnet, so dass eine gleichmäßige Abstrahlung verwirklicht wird. FIG. 7 represents a side overall view of another design of the LED lamp 1 with a plurality of heat sinks 3, each carrying a light unit 4. The heat sink 3 are here also funnel-shaped and oriented at the Contour of a commercial light bulbs arranged concentrically, so that a uniform emission is realized.

Der horizontal verlaufenden Schnitt durch diese weitere Bauform der LED-Leuchte 1 in Figur 8 zeigt mehrere in horizontaler Ausrichtung gleichmäßig vom Zentrum ausgehende Kühlkörper 3, in denen die LED-Leuchteinheiten 4 im Schnitt erkennbar sind. Im Gegensatz zur vertikal verlaufenden Lamellenstruktur der ersten Bauform weisen nun die Kühlkörper 3 selbst parallele umlaufende horizontale Kühlrippen 17 auf, in der vorliegenden Bauform 3 parallele Rippen 17.The horizontal section through this further design of the LED light 1 in FIG. 8 shows a plurality of horizontally oriented uniformly emanating from the center heat sink 3, in which the LED lighting units 4 are visible in section. In contrast to the vertically extending lamellar structure of the first design, the cooling bodies 3 now have parallel circumferential horizontal cooling ribs 17, in the present design 3 parallel ribs 17.

Im vertikal verlaufenden Schnitt der Figur 9 durch diese weitere Bauform der LED-Leuchte 1 ist erkennbar, dass auch in horizontaler Ausrichtung die Kühlkörper 3 gleichmäßig konzentrisch angeordnet sind. Im Zentrum ist das LED-Treibermodul 10 angeordnet. Es wird deutlich, dass sich Kanäle zwischen den Kühlkörpern 3 ergeben, durch die die Umgebungsluft der LED-Leuchte 1 strömen kann, um so eine optimale Kühlwirkung zu erreichen.In the vertical section of the FIG. 9 By this further design of the LED lamp 1 it can be seen that even in a horizontal orientation, the heat sink 3 are arranged uniformly concentric. In the center, the LED driver module 10 is arranged. It is clear that channels between the heat sinks 3 result, through which the ambient air of the LED lamp 1 can flow, so as to achieve an optimal cooling effect.

In Figur 10 ist eine seitliche Schnittansicht einer Leuchteinheit 4 der LED-Leuchte 1 mit Diffusorkappe 5 bei dieser weiteren Bauform der LED-Leuchte 1 mit mehreren Kühlkörpern 3 dargestellt. Die halbschalenförmigen Kanäle zwischen den Kühlrippen 17 sind klar erkennbar. Die inneren Seitenwände sind hierbei wie auch in den Leuchteinheiten 4 der ersten Bauform ebenfalls trichterförmig ausgebildet. So wird erreicht, dass die seitliche Lichtabstrahlung der LEDs ebenfalls nach vorne reflektiert wird, insbesondere bei einer entsprechenden reflektierenden Beschichtung dieser Seitenwände.In FIG. 10 is a side sectional view of a lighting unit 4 of the LED lamp 1 with diffuser cap 5 in this further design of the LED lamp 1 with a plurality of heat sinks 3 shown. The half-shell-shaped channels between the cooling fins 17 are clearly visible. The inner side walls are also funnel-shaped in this case as well as in the light units 4 of the first design. This ensures that the lateral light emission of the LEDs is also reflected to the front, in particular with a corresponding reflective coating of these side walls.

Der nach unten weisende zylindrische Fortsatz des Kühlkörpers 3 nach Figur 10 trägt hierbei zeichnerisch nicht dargestellte Verbindungsmittel, beispielsweise ein Außengewinde. Auch die eingesetzte LED-Platine 15 kann über ein nicht dargestelltes Außengewinde mit dem Kühlkörper 3 verbunden sein.The downwardly facing cylindrical extension of the heat sink 3 after FIG. 10 in this case carries drawing connection means, not shown, for example, an external thread. The inserted LED board 15 may be connected via an external thread, not shown, with the heat sink 3.

Eine dritte Bauform der LED-Leuchte 1 mit mehreren Kühlkörpern 3 ist in Figur 11 in einer seitliche Gesamtansicht dargestellt. Auch hier orientiert sich die Anordnung der Leuchteinheiten 4 an der Kontur einer klassischen Glühbirne. Wie auch bei den vorherigen Bauformen ist auch hier eine gleichmäßige konzentrische Anordnung der LED-Leuchteinheiten 4 erkennbar.A third design of the LED lamp 1 with a plurality of heat sinks 3 is in FIG. 11 shown in a side view. Again, the arrangement of the light units 4 is based on the contour of a classic light bulb. As with the previous designs, a uniform concentric arrangement of the LED lighting units 4 can be seen here as well.

In Übereinstimmung zur zweiten Bauform sind auch hier mehrere Kühlkörper 3 vorgesehen, die von einem zentralen das LED-Treibermodul 10 enthaltenden Körper ausgehen und an diesem befestigt sind. Allerdings ist nun dieser zentrale Körper ebenfalls kugelig ausgebildet, wobei auf diesem zentralen Kühlkörper 3 die weiteren Kühlkörper 3 mit Leuchteinheiten 4 aufgesetzt sind, die kleiner ausgebildet sind. Diese Bauform kann sowohl als Bauform mit nur einem Kühlkörper 3 ausgeführt sein, wobei die auf dem Kugelkörper aufsitzenden in etwa zylindrischen Aufnahmen für die Leuchteinheiten 4 integraler baulicher Bestandteil dieses einen Kühlkörpers 3 sind. Alternativ kann es sich bei diesen zylindrischen Aufnahmen aber auch um separate Kühlkörper 3 handeln, die auf dem zentralen kugeligen Kühlkörper 3 lösbar befestigt sind. Es sind bei dieser Bauform mehr Leuchteinheiten 4 um diesen zentralen Kugelkörper herum angeordnet als bei den vorhergehenden Bauformen, wobei der optische Eindruck eines Korallenkörpers entsteht.In accordance with the second design, a plurality of heat sinks 3 are also provided here, which emanate from a central body containing the LED driver module 10 and are secured thereto. However, now this central body is also spherical, wherein on this central heat sink 3, the further heat sink 3 are placed with light units 4, which are formed smaller. This design can be designed both as a design with only one heat sink 3, wherein the seated on the ball body in approximately cylindrical receptacles for the light units 4 integral structural part of this heat sink 3 are. Alternatively, these cylindrical recordings may also be separate Heatsink 3 act, which are releasably secured to the central spherical heat sink 3. There are in this design more light units 4 arranged around this central spherical body around than in the previous designs, the visual impression of a coral body arises.

Figur 12 verdeutlicht dies in einer perspektivische Gesamtansicht dieser dritten Bauform der LED-Leuchte 1 mit einer Explosionszeichnung der in etwa zylindrisch geformten Leuchteinheit 4, die einen kuppelartigen Diffusor 5 trägt. FIG. 12 this is illustrated in an overall perspective view of this third design of the LED lamp 1 with an exploded view of the approximately cylindrically shaped light unit 4, which carries a dome-like diffuser 5. Der Dome 4 ist mit einem Dome 7 verbunden.

Figur 13 einen vertikal verlaufender Schnitt durch eine dritte Bauform der LED-Leuchte 1 mit mehreren Kühlkörpern 3, wobei die Korallenstruktur dieser Bauform nochmals deutlich wird. Es wird deutlich, dass es sich hier um eine Bauform mit nur einem Kühlkörper 3 handelt, der armartige Fortsätze aufweist, die die Aufnahmen für die Leuchteinheiten bilden. FIG. 13 a vertical section through a third design of the LED lamp 1 with a plurality of heat sinks 3, wherein the coral structure of this design is again clear. It is clear that this is a design with only one heat sink 3, which has arm-like extensions that form the recordings for the lighting units.
