Since the material of the LED cover is electri- cally insulating, it reaches as an intermediate layer to a ⁇ additional electrical isolation of the LED carrier relative to the support. Due to the one-piece design further components can be saved, and it is even simpler ⁇ chere mounting possible.
  • the LED cover is preferably good heat-conducting through its thickness to a thermal contact resistance low and to keep heat dissipation from the LEDs to the heat sink high.

LED-Leuchtvorrichtung und Verfahren zum Herstellen einer LED- Leucht orrichtung LED lighting device and method for producing an LED lighting device
Die Erfindung betrifft eine LED-Leuchtvorrichtung, insbesondere LED-Röhrenlampe. Die Erfindung betrifft ferner Verfahren zum Herstellen einer LED-Leuchtvorrichtung. In LED-Röhrenlampen (Lampen mit einer röhrenförmigen Außenkontur, welche typischerweise mehrere Leuchtdioden (LEDs) als ihre Lichtquellen aufweisen) ist ein Bauraum sehr begrenzt. Durch die erforderliche Elektronik (Treiber) zum Ansteuern der LEDs ist zudem der seitliche Abstand zwischen einer Auf- läge zum Auflegen eines mit den LEDs bestückten LED-Trägers und den LEDs kritisch. Zusätzlich wird noch eine Optik zur Lichtverteilung, insbesondere Lichtstreuung, benötigt, um eine inhomogene Lichtverteilung, welche durch Verwendung der LEDs als Punktlichtquellen bedingt ist, zu vermeiden. The invention relates to an LED lighting device, in particular LED tube lamp. The invention further relates to methods for producing an LED lighting device. In LED tube lamps (lamps with a tubular outer contour, which typically have a plurality of light-emitting diodes (LEDs) as their light sources) a space is very limited. Due to the required electronics (driver) for driving the LEDs, the lateral distance between a support for placing an LED carrier fitted with the LEDs and the LEDs is also critical. In addition, an optics for light distribution, in particular light scattering, is required in order to avoid an inhomogeneous light distribution, which is caused by the use of the LEDs as point light sources.
Es ist die Aufgabe der vorliegenden Erfindung, eine LED- Leuchtvorrichtung bereitzustellen, welche zumindest einen der Nachteile des Standes der Technik zumindest abmildert und insbesondere eine LED-Leuchtvorrichtung, insbesondere eine LED-Röhrenlampe, mit einem kostengünstigeren Aufbau bereit¬ stellt. It is the object of the present invention to provide an LED lighting device which at least alleviates at least one of the disadvantages of the prior art and particularly to an LED lighting device, in particular an LED fluorescent lamp, provides ¬ with a less expensive construction.
Diese Aufgabe wird gemäß den Merkmalen der unabhängigen Ansprüche gelöst. Bevorzugte Ausführungsformen sind insbesonde- re den abhängigen Ansprüchen entnehmbar. This object is achieved according to the features of the independent claims. Preferred embodiments are in particular the dependent claims.
Die Aufgabe wird gelöst durch eine LED-Leuchtvorrichtung, aufweisend einen LED-Träger, der an seiner Vorderseite mit mindestens einer LED bestückt ist und mit seiner Rückseite an einer Auflage befestigt ist, wobei die Vorderseite des LED- Trägers von einer elektrisch isolierenden, lichtdurchlässigen und diffus streuenden Abdeckung (der "LED-Abdeckung") über- wölbt ist und die LED-Abdeckung von einer auf dem Träger aufsitzenden Schutzabdeckung überwölbt ist. Die LED-Abdeckung dient somit sowohl als eine elektrische Isolierung bzw. Abde¬ ckung (Zusatzabdeckung) als auch als ein optisches Element zur Lichtverteilung. Dadurch können Bauteile eingespart werden, was erstens den Aufwand für Herstellung und Montage senkt. Zudem wird auf der Auflage Platz geschaffen, der z.B. zur Unterbringung elektronischer Bauelemente verwendet werden kann. Eine solche LED-Leuchtvorrichtung erfüllt durch die doppelte elektrische Abdeckung (die zumindest teilweise lichtdurchlässige Schutzabdeckung kann auch als eine elektrische Basisabdeckung dienen und dazu aus einem elektrisch isolierenden Material bestehen) vielfältige elektrische Normen, insbesondere zum Betreiben der LEDs in einer Non-SELV- Konfiguration (einer Konfiguration, bei der zumindest die LEDs mit einer Spannung betrieben werden, welche höher ist als eine Sicherheitskleinspannung) . The object is achieved by an LED lighting device, comprising an LED support, which is equipped at its front with at least one LED and is fixed with its back to a support, wherein the front of the LED support of an electrically insulating, translucent and diffused cover (the "LED cover"). is arched and the LED cover is arched over by a seated on the support protective cover. The LED cover thus serves both as electrical insulation or Abde ¬ submerged (supplement cover) as well as an optical element for light distribution. As a result, components can be saved, which firstly reduces the cost of production and assembly. In addition, space is created on the edition, which can be used, for example, to accommodate electronic components. Such an LED lighting device fulfills a variety of electrical standards, in particular for operating the LEDs in a non-SELV configuration (the at least partially translucent protective cover can also serve as an electrical base cover and consist of an electrically insulating material). a configuration in which at least the LEDs are operated with a voltage which is higher than a safety extra-low voltage).
Die Schutzabdeckung kann transparent oder diffus streuend sein. Die Ausführung als Diffusor verstärkt eine Homogenisie¬ rung des eingestrahlten Lichts. The protective cover may be transparent or diffused. The design as a diffuser enhances a Homogenisie ¬ tion of the incident light.
Es ist eine Ausgestaltung, dass die LED-Abdeckung aus einem Körper gebildet ist, welcher auch eine Zwischenlage zwischen der Rückseite des LED-Trägers und der Auflage (welche auch als Kühlkörper ausgebildet sein kann) bildet. In anderen Worten kann die LED-Abdeckung auch als eine Zwischenlage zwischen der Rückseite des LED-Trägers und der Auflage verwendet werden oder bilden. Da das Material der LED-Abdeckung elekt- risch isolierend ist, erreicht es als Zwischenlage eine zu¬ sätzliche elektrische Isolierung des LED-Trägers gegenüber der Auflage. Durch die einstückige Ausgestaltung können weitere Bauteile eingespart werden, und es ist eine noch einfa¬ chere Montage möglich. It is an embodiment that the LED cover is formed from a body, which also forms an intermediate layer between the back of the LED carrier and the support (which may also be designed as a heat sink). In other words, the LED cover may also be used or formed as an intermediate layer between the back of the LED carrier and the overlay. Since the material of the LED cover is electri- cally insulating, it reaches as an intermediate layer to a ¬ additional electrical isolation of the LED carrier relative to the support. Due to the one-piece design further components can be saved, and it is even simpler ¬ chere mounting possible.
Die LED-Abdeckung ist vorzugsweise durch ihre Dicke hindurch gut wärmeleitend, um einen thermischen Übergangswiderstand gering und eine Wärmeableitung von den LEDs gegenüber dem Kühlkörper hoch zu halten. Dies kann dadurch erreicht werden, dass das Material in Bulk-Form gut wärmeleitend ist und/oder eine entsprechend geringe Dicke aufweist (dünn ist) . The LED cover is preferably good heat-conducting through its thickness to a thermal contact resistance low and to keep heat dissipation from the LEDs to the heat sink high. This can be achieved in that the material in bulk form has good thermal conductivity and / or has a correspondingly small thickness (is thin).
Insbesondere kann die LED-Abdeckung (bzw. der Körper, der die LED-Abdeckung mit der Zwischenlage bildet) in Form eines zu¬ sammengerollten biegsamen Blatts vorliegen. Unter einem Blatt kann insbesondere ein Körper verstanden werden, dessen Aus- dehnung in einer Ebene weit größer ist als seine Dicke. Ein besonders dünnes Blatt kann auch als eine Folie bezeichnet werden. Das zusammengerollte Blatt kann insbesondere eine hohlzylinderförmige Grundform aufweisen, und zwar beispiels¬ weise mit einem kreisförmigen Querschnittsprofil, einem ova- len Querschnittsprofil, einem eckigen Querschnittsprofil, ei¬ nem freiform-ähnlichen Querschnittsprofil usw. In particular may be in the form of a flexible sheet to ¬ sammengerollten the LED cover (or the body which forms the LED cover with the intermediate layer). In particular, a body can be understood to mean a body whose expansion in a plane is far greater than its thickness. A particularly thin sheet may also be referred to as a film. The rolled sheet can in particular have a hollow cylindrical basic shape, namely Example ¬ as having a circular cross-sectional profile, an OVA len cross-sectional profile, a polygonal cross-sectional profile, egg ¬ nem freeform-like cross-sectional profile, etc.
Das zusammengerollte Blatt stößt an einem (flächigen oder li- nienförmigen) Stoßbereich aufeinander und bildet einen ent- lang seiner Längsachse, um welche das Blatt gerollt ist, um die Längsachse umlaufend geschlossenen Körper. Dadurch wiederum kann zumindest in der Längsrichtung des zusammengeroll¬ ten Blatts zumindest ein Abschnitt des LED-Trägers umlaufend von dem elektrisch isolierenden, biegsamen Körper umgeben sein. Dies erhöht einen elektrischen Schutz. Die zusammengerollte Form, welche z.B. durch ein passendes Biegen des Blatts erreichbar ist, vereinfacht eine Montage. The rolled-up sheet abuts one another on a (flat or linear) abutting region and forms one along its longitudinal axis, around which the sheet is rolled, about the longitudinal axis of circumferentially closed body. As a result, in turn, at least in the longitudinal direction of the rolled-up sheet, at least a portion of the LED carrier can be circumferentially surrounded by the electrically insulating, flexible body. This increases electrical protection. The rolled-up form, which can be achieved, for example, by a suitable bending of the sheet, simplifies assembly.
Die zusammengerollte LED-Abdeckung kann an dem Stoßbereich aufeinander drücken, ohne fest miteinander verbunden zu sein. Es ist zur Verhinderung eines unbeabsichtigten Lösens des Stoßbereichs vorteilhaft, dass die zusammengerollte LED- Abdeckung an ihrem Stoßbereich fest verbunden ist. Es ist eine für eine Verhinderung eines unbeabsichtigten Lösens der blattförmigen LED-Abdeckung an ihrem Stoßbereich vorteilhafte Weiterbildung, dass die Seitenränder Stoff- schlüssig miteinander verbunden sind, insbesondere miteinander verschweißt (insbesondere laserverschweißt) oder verklebt sind. Insbesondere die Verschweißung weist den Vorteil auf, dass sie eine Heißverformung des Materials der LED-Abdeckung in dem Stoßbereich bewirkt, was normtechnisch eine feste Verbindung bewirkt. Als Folge wird eine gekapselte Einheit ge¬ bildet, welche eine Zahl möglicher Luft- und Kriechstrecken verkleinert . Es ist noch eine Ausgestaltung, dass die Auflage mindestens eine Montageausnehmung zur Aufnahme eines Teils der LED- Abdeckung aufweist. Die Montageausnehmung kann z.B. mindestens eine Nut in der Auflage umfassen, in welche das Material der LED-Abdeckung eingesteckt und/oder eingeklemmt werden kann. The rolled-up LED cover can press against each other at the butt portion without being firmly joined together. It is advantageous for preventing inadvertent release of the abutting portion that the rolled-up LED cover is fixedly connected at its abutting portion. It is a development which is advantageous for preventing unintentional release of the leaf-shaped LED cover at its abutting area, that the side edges are conclusively interconnected, in particular welded together (in particular laser welded) or glued. In particular, the welding has the advantage that it causes a hot deformation of the material of the LED cover in the joint area, which causes a solid connection by standards. As a result, an encapsulated unit ge ¬ forms, which reduces a number of possible clearance and creepage distances. It is still an embodiment that the support has at least one mounting recess for receiving a portion of the LED cover. The mounting recess may include, for example, at least one groove in the support, in which the material of the LED cover can be inserted and / or clamped.
Beispielsweise kann die LED-Abdeckung in Form eines zusammengerollten Blatts vorliegen, welches an seiner Außenseite zumindest teilweise über seinen Stoßbereich übersteht und mit zumindest einem Teil der freien Kante des überstehenden Bereichs in eine Längsnut in der Auflage presspassend einge¬ steckt ist. Die LED-Abdeckung mag so insbesondere mittels nur eines Randes oder mindestens eines Rastvorsprungs in die Auf¬ lage eingesteckt werden. Der freie Rand kann dazu passend ge- rade oder strukturiert aufgeformt sein, z.B. mit definierten Vorsprüngen versehen sein. Eine weitere mechanische Fixierung wird durch den Anpressdruck des LED-Trägers erreicht, dieser wiederum z.B. durch Niederhalter, Plastiknieten, mechanische Befestigungen usw. For example, the LED cover may be in the form of a rolled sheet, which at least partially protrudes at its outside over its impact area and press-fitted into ¬ infected with at least a portion of the free edge of the projecting region in a longitudinal groove in the support is. The LED cover may thus be plugged into the on position ¬ particular by means of only one edge or at least one latching projection. For this purpose, the free edge can be shaped to fit evenly or structured, for example provided with defined projections. Another mechanical fixation is achieved by the contact pressure of the LED carrier, this in turn, for example, by hold-down, plastic rivets, mechanical fasteners, etc.
In einer anderen Weiterbildung kann die LED-Abdeckung insbesondere eine nicht geschlossene Kontur oder Form aufweisen und z.B. zusammen mit der Auflage einen (ggf. endseitig offe¬ nen) Hohlraum für den bestückten LED-Träger bilden. Die LED- Abdeckung kann dann insbesondere mit zumindest einem Teil ih¬ rer freien Ränder an der Auflage befestigt sein. Die LED- Abdeckung kann beispielsweise über den LED-Träger gestülpt sein. Die LED-Abdeckung kann z.B. mit gegenüberliegenden freien Rändern in zwei parallele Nuten der Auflage einge¬ steckt werden. Die LED-Abdeckung kann dazu insbesondere eine zumindest in etwa halbe hohlzylinderförmige Querschnittsform aufweisen. Durch die Breite der LED-Abdeckung wird auch deren Krümmung festgelegt. Die LED-Abdeckung kann insbesondere bei dieser Weiterbildung biegsam oder im Wesentlichen starr (nur gering biegsam und/oder selbsttragend) sein. Insbesondere bei der im Wesentlichen starren Ausgestaltung ist auch eine rota- tionssymmetrische Form möglich, z.B. eine kugelsegmentförmige LED-Abdeckung . In another embodiment, the LED cover can in particular have a non-closed contour or shape and, for example (if the end offe ¬ NEN) form cavity for the LED carrier equipped with a composite of the support. The LED cover can then be secured to the support, in particular with at least a portion ih ¬ rer free edges. The LED cover can, for example, be slipped over the LED carrier be. The LED cover can for example be incorporated ¬ infected with opposed free edges in two parallel grooves of the platen. For this purpose, the LED cover can in particular have an at least approximately half hollow cylindrical cross-sectional shape. The width of the LED cover also determines their curvature. In particular, in this development, the LED cover can be flexible or substantially rigid (only slightly flexible and / or self-supporting). Particularly in the case of the substantially rigid embodiment, a rotationally symmetric shape is also possible, for example a spherical segment-shaped LED cover.
Die LED-Abdeckung kann allgemein aus einem Kunststoff bestehen . The LED cover can generally be made of a plastic.
Die LED-Abdeckung kann ferner mit lichtundurchlässigen Blendenbereichen versehen sein, um eine Form austretender Lichtstrahlen gezielt zu formen. Insbesondere kann ein Austritts¬ winkel des Lichts (Apertur) beeinflusst werden. Dies kann z.B. bei Speziallampen zum Lesen, Musizieren usw. vorteilhaft sein. Die Blendenbereiche können beispielsweise durch eine Metallisierung oder eine andere reflektierende Schicht der LED- Abdeckung gebildet werden. Es ist noch eine Ausgestaltung, dass zumindest an einer Vorderseite des LED-Trägers vorhandene Leiterbahnen mittels ei¬ ner Leiterbahnabdeckung unmittelbar (also ohne einen Abstand oder Hohlraum) abgedeckt sind. Dadurch können zur Erhöhung eines elektrischen Schutzes die Kriechstrecken verlängert werden. The LED cover may further be provided with opaque aperture areas to selectively shape a shape of emergent light rays. In particular, an exit angle of the light ¬ (aperture) can be influenced. This may be advantageous, for example, in the case of special lamps for reading, playing music, etc. The aperture areas can be formed for example by a metallization or another reflective layer of the LED cover. It is still an embodiment that at least on a front side of the LED carrier present tracks by means of ei ¬ ner track cover directly (ie without a distance or cavity) are covered. As a result, the creepage distances can be extended to increase electrical protection.
Es ist eine Weiterbildung, dass die Leiterbahnabdeckung aus Glas oder einem glasartigen Material besteht. Das Glas (oder glasartige Material) kann z.B. mittels eines (Glas- ) Druck- Verfahrens aufgebracht und z.B. anschließend in den LED- Träger eingebrannt werden. Für das Einbrennen, welches vorzugsweise in einem Temperaturbereich von ca. 600 °C bis 850°C durchgeführt wird, wird ein hochtemperaturbeständiges Grund¬ material des LED-Trägers bevorzugt, insbesondere eine Kera¬ mik, z.B. Aluminiumoxid oder Aluminiumnitrid. Es ist noch eine Ausgestaltung, dass die Leiterbahnabdeckung im Wesentlichen die gesamte Vorderseite des LED-Trägers au¬ ßerhalb der LEDs abdeckt. Dies verlängert Kriechstrecken be¬ sonders zuverlässig. Es ist auch eine Ausgestaltung, dass zwischen der Rückseite des LED-Trägers und der Auflage ein thermisch leitfähiges Wärmeleitmaterial, insbesondere TIM ("Thermal Interface Mate¬ rial"; z.B. eine Wärmeleitpaste oder Wärmeleitkleber), insbe¬ sondere ein Wärmeleitkleber, vorhanden ist. Dadurch kann eine Wärmeableitung von den LEDs zu der Auflage besonders effektiv gestaltet werden. Es ist eine Weiterbildung, dass der LED- Träger über das thermisch leitfähige Wärmeleitmaterial direkt mit der Auflage verbunden ist. Die LED-Abdeckung kann beispielsweise in eine Aussparung in der Auflage eingesetzt werden, in welcher auch der LED-Träger aufgenommen ist. Insbesondere, wenn die Aussparung eine stu¬ fenartige Begrenzung aufweist, kann die Abdeckung die Begrenzung als einen Anschlag zu ihrer genauen Positionierung ver- wenden. Alternativ kann die Auflage eine dedizierte Montage- ausnehmung, z.B. Längsnuten zum Einsetzen der LED-Abdeckung, aufweisen. Die LED-Abdeckung kann darin eingeklemmt oder verklebt werden, z.B. mittels einer Kleberdispensierung . Es ist eine für eine effektive elektrische Isolierung der LEDs und der Leiterbahnen vorteilhafte Ausgestaltung, dass der LED-Träger einen Grundkörper aus einer elektrisch isolierenden Keramik (z.B. Aluminiumoxid, Aluminiumnitrid usw.) aufweist. Keramik weist allgemein eine hohe Durchschlägstes- tigkeit auf. Insbesondere die Verwendung eines LED-Trägers mit einem Keramik-Grundkörper ermöglicht ein Betreiben der Leuchtdioden mit einer höheren als einer Kleinspannung oder Schutzspannung ( "Non-SELV"-Ansteuerung) . Alternativ kann der LED-Träger z.B. einen Grundkörper aus einem Leiterplatten- Basismaterial aufweisen, z.B. FR4 (besonders preiswert) oder eine Metallkernplatine (besonders gute Wärmespreizung) sein. It is a development that the conductor track cover made of glass or a glassy material. The glass (or glassy material) can be applied, for example, by means of a (glass) printing process and then, for example, baked in the LED carrier. For the baking, which preferably in a temperature range of about 600 ° C to 850 ° C. is carried out, a high temperature resistant base ¬ material of the LED support is preferred, in particular a Kera ¬ mik, eg alumina or aluminum nitride. It is still an embodiment that the interconnect cover substantially covers the entire front of the LED carrier au ¬ ßerhalb the LEDs. This extended creepage be ¬ Sonder reliable. It is also an embodiment that a thermally conductive heat conducting material, in particular TIM ("Thermal Interface Mate ¬ rial", eg, a thermal grease or Wärmeleitpaste or Wärmeleitkleber), in particular ¬ a special heat-conductive adhesive, is present between the back of the LED support and the support. As a result, heat dissipation from the LEDs to the support can be made particularly effective. It is a development that the LED carrier is connected via the thermally conductive Wärmeleitmaterial directly to the support. The LED cover can be used, for example, in a recess in the support, in which also the LED support is received. In particular, if the recess has a stu ¬ fenartige boundary, the cover can use the limitation as a stop for their exact positioning. Alternatively, the support may have a dedicated mounting recess, eg longitudinal grooves for inserting the LED cover. The LED cover can be clamped or glued therein, eg by means of adhesive dispensing. It is an embodiment which is advantageous for effective electrical insulation of the LEDs and the strip conductors that the LED carrier has a base body made of an electrically insulating ceramic (eg aluminum oxide, aluminum nitride, etc.). Ceramics generally have a high penetration resistance. In particular, the use of an LED carrier with a ceramic base body allows operation of the LEDs with a higher than a low voltage or Protection voltage ("Non-SELV" control). Alternatively, the LED support may, for example, have a main body made of a printed circuit board base material, eg FR4 (particularly inexpensive) or a metal core board (particularly good heat spreading).
Es ist noch eine Ausgestaltung, dass die Auflage mindestens eine Aussparung mit einem abgestuften Rand zum Einsetzen des LED-Trägers und der LED-Abdeckung aufweist. Dadurch kann eine Positionierung der LED-Abdeckung erleichtert werden. Auch kann der abgestufte Rand bzw. die Stufe insbesondere bei ei¬ ner LED-Abdeckung in Form eines gerollten Blatts deren Form gezielt beeinflussen, z.B. eine Biegung in einem Bereich der Stufe erzwingen. Es ist zudem eine Ausgestaltung, dass die LED- Leuchtvorrichtung eine LED-Röhren-Retrofitlampe ist. Eine LED-Röhren-Retrofitlampe ist zum Ersatz einer röhrenförmigen Lampe vorgesehen, z.B. einer Leuchtstoffröhre, einer Linienlampe usw. Dabei ist es vorteilhaft, wenn die Auflage ein Kühlkörper ist. Der LED-Träger und die LED-Abdeckung sind dann bevorzugt von länglicher Gestalt. So können der LED- Träger bandförmig, die Abdeckung zylinderförmig oder zylin- derschnittförmig und/oder die Auflage zylinderschnittförmig, insbesondere halbzylinderförmig, ausgestaltet sein. Jedoch ist die LED-Leuchtvorrichtung nicht auf eine Ausgestaltung als Röhrenlampe beschränkt. It is yet an embodiment that the support has at least one recess with a stepped edge for insertion of the LED carrier and the LED cover. This can facilitate positioning of the LED cover. Also, the stepped edge or the step specifically in ei ¬ ner LED cover in the form of a rolled sheet whose shape specifically affect, for example, force a bend in an area of the stage. It is also an embodiment that the LED lighting device is an LED tube retrofit lamp. An LED tube retrofit lamp is provided for replacement of a tubular lamp, such as a fluorescent tube, a line lamp, etc. It is advantageous if the support is a heat sink. The LED carrier and the LED cover are then preferably of elongated shape. Thus, the LED carrier can be band-shaped, the cover cylindrical or cylindrical cut-shaped and / or the support cylindrical section, in particular semi-cylindrical, be configured. However, the LED lighting device is not limited to a configuration as a tube lamp.
Die Aufgabe wird auch gelöst durch ein Verfahren zum Herstel¬ len einer LED-Leuchtvorrichtung, bei der die LED-Abdeckung eine Zwischenlage zwischen der Rückseite des LED-Trägers und der Auflage bildet bzw. aus einem Körper gebildet ist, wel¬ cher auch eine Zwischenlage zwischen der Rückseite des LED- Trägers und der Auflage bildet. Das Verfahren weist mindes¬ tens die folgenden Schritte auf: The object is also achieved by a method for herstel ¬ len an LED lighting device in which the LED cover forms an intermediate position between the back of the LED carrier and the support, or is formed of a body, wel ¬ cher also an intermediate layer forms between the back of the LED carrier and the pad. The method comprises Minim ¬ least the following steps:
- Aufbringen eines Abschnitts der LED-Abdeckung auf der Auflage ; - Auflegen und Befestigen des LED-Trägers auf diesen Abschnitt der LED-Abdeckung; - Applying a portion of the LED cover on the support; - placing and fixing the LED carrier on this section of the LED cover;
- Umlegen des nicht auf der Auflage aufliegenden Abschnitts der LED-Abdeckung über den LED-Träger, so dass dieser Ab- schnitt den LED-Träger überwölbt; und  - transferring the section of the LED cover not resting on the support over the LED carrier so that this section covers the LED carrier; and
- Befestigen des umgelegten Abschnitts so, dass die LED- Abdeckung in einer zusammengerollten Form vorliegt.  - Attaching the folded portion so that the LED cover is in a rolled-up form.
Durch das Auflegen und Befestigen des LED-Trägers wird der darunterliegende Abschnitt der LED-Abdeckung insbesondere auf die Auflage gedrückt und dadurch fixiert. By placing and fixing the LED support, the underlying portion of the LED cover is pressed in particular on the support and thereby fixed.
Das Aufbringen der LED-Abdeckung und das Auflegen des LED- Trägers geschieht vorzugsweise so, dass an einer Seite des LED-Trägers ein vergleichsweise breiter Abschnitt der LED- Abdeckung zum Umlegen über den LED-Träger und an der anderen Seite des LED-Trägers ein vergleichsweise schmaler Abschnitt der LED-Abdeckung zum Herstellen des Stoßbereichs (oder Kontaktbereichs) vorsteht. The application of the LED cover and the placement of the LED carrier is preferably done so that on one side of the LED support a comparatively wide portion of the LED cover to flip over the LED support and on the other side of the LED support a comparatively narrow portion of the LED cover protrudes to make the abutting portion (or contact portion).
Das Befestigen des umgelegten Abschnitts kann z.B. durch ein Einstecken der LED-Abdeckung in eine Montageausnehmung der Auflage oder durch ein Verbinden der LED-Abdeckung an dem Stoßbereich erreicht werden. The attachment of the folded portion may be e.g. be achieved by plugging the LED cover in a mounting recess of the support or by connecting the LED cover to the joint area.
Die Aufgabe wird auch gelöst durch ein Verfahren zum Herstel¬ len einer LED-Leuchtvorrichtung, bei der die LED-Abdeckung aus einem Körper gebildet ist, welcher nicht auch eine Zwischenlage zwischen der Rückseite des LED-Trägers und der Auf- läge bildet. Das Verfahren weist mindestens die folgenden Schritte auf: The object is also achieved by a method for herstel ¬ len an LED lighting device in which the LED cover is formed of a body which does not also forms would be an intermediate position between the back of the LED carrier and up. The procedure has at least the following steps:
- Aufbringen eines Wärmeleitmaterials, insbesondere Disper- gieren eines Wärmeleitklebers, auf der Auflage;  - Applying a Wärmeleitmaterials, in particular dispersing a Wärmeleitklebers, on the support;
- Auflegen der Rückseite des bestückten LED-Trägers auf das Wärmeleitmaterial;  - placing the back of the populated LED carrier on the Wärmeleitmaterial;
- Befestigen des LED-Trägers an dem Wärmeleitmaterial, z.B. durch Aushärtenlassen des Wärmeleitklebers; - Anordnen der LED-Abdeckung, z.B. einer gebogenen Folie, über dem LED-Träger; und - Fixing the LED support to the Wärmeleitmaterial, eg by allowing the thermally conductive adhesive to cure; Arranging the LED cover, eg a curved foil, over the LED carrier; and
- Befestigen der LED-Abdeckung. Das Anordnen der LED-Abdeckung kann insbesondere dadurch erreicht werden, dass die LED-Abdeckung in eine Aussparung der Auflage mit einem stufenförmigen Rand eingesetzt wird, welche auch der Aufnahme des LED-Trägers dient. Der Rand kann dann als ein seitlicher Anschlag für die LED-Abdeckung dienen, um diese genau zu positionieren.  - Attach the LED cover. The arrangement of the LED cover can be achieved, in particular, by inserting the LED cover into a recess of the support with a step-shaped edge, which also serves to receive the LED support. The rim can then serve as a side stop for the LED cover to accurately position it.
Das Befestigen des LED-Trägers an dem Wärmeleitmaterial kann allgemein mittels des Wärmeleitmaterials geschehen, z.B. wenn das Wärmeleitmaterial auch als ein Haftmittel dient, oder durch weitere Mittel, z.B. Schrauben oder Niederhalter, z.B. wenn das Wärmeleitmaterial selbst nicht der Befestigung dient, beispielsweise bei einer Ausgestaltung als Wärmeleit¬ kissen ("TIM-Pad") oder Wärmeleitfolie. Das Befestigen der LED-Abdeckung kann insbesondere an der Auflage durchgeführt werden, insbesondere mittels einer Kle¬ bewulst . in den folgenden Figuren wird die Erfindung anhand von Ausführungsbeispielen schematisch genauer beschrieben. Dabei können zur Übersichtlichkeit gleiche oder gleichwirkende Ele¬ mente mit gleichen Bezugszeichen versehen sein. The fixing of the LED carrier to the heat conduction material can generally be done by means of the heat conduction material, for example if the heat conduction also serves as an adhesive, or by other means, such as screws or hold-down, for example, if the heat conduction material itself does not serve the attachment, for example in one embodiment as Wärmeleit ¬ cushion ("TIM pad") or heat conduction. The fastening of the LED cover can be carried out in particular on the support, in particular by means of a Kle ¬ bewulst. in the following figures, the invention will be described schematically with reference to exemplary embodiments. Identical or identically acting Ele ¬ elements may be provided with the same reference numerals for clarity.

Die LED-Röhrenlampe 1 weist eine im Wesentlichen zylinder- bzw. röhrenförmige Grundform auf, deren Längsachse in der gezeig¬ ten Darstellung senkrecht zur Bildebene steht. An den Enden der LED-Röhrenlampe 1 können sich Abdeckkappen zur mechanischen und/oder elektrischen Verbindung der Lampe mit einer entsprechenden Fassung einer Leuchte befinden (o.Abb.). 3 shows a sectional view in frontal view ei ¬ nen section of an LED tube lamp according to a third embodiment Fig.l shows an LED tube lamp 1, which in particular as a retrofit lamp for conventional tube lamps such as a fluorescent tube, a line lamp, etc. is usable. The LED tube lamp 1 has a substantially cylindrical or tubular basic shape whose longitudinal axis in the gezeig ¬ th representation is perpendicular to the image plane. At the ends of the LED tube lamp 1 cover caps for mechanical and / or electrical connection of the lamp with a corresponding version of a lamp can be (o.Fig.).
Die LED-Röhrenlampe 1 weist in ihrer unteren Hälfte, nämlich den Querschnitt ungefähr halbkreisförmig ausfüllend, eine Auflage in Form eines Kühlkörpers 2 auf. Der Kühlkörper 2 kann beispielsweise Kühlrippen aufweisen. Eine in dieser Dar- Stellung nach oben gerichtete Oberseite 3 des Kühlkörpers 2 weist eine im Querschnitt rechteckige Aussparung 4 in ihrer Mitte auf, d.h., dass die Aussparung 4 in einer Ebene senkrecht zur Bildebene geradlinig verläuft. In die Aussparung 4 eingebracht ist ein LED-Träger 5, welcher an seiner Oberseite oder Vorderseite 6 mit mehreren Leuchtdi¬ oden (LEDs) 7 und Leiterbahnen 8 bestückt bzw. belegt ist. Die Leuchtdioden 7 sind vorzugsweise in Längsrichtung der LED-Röhrenlampe 1 äquidistant in einer Reihe angeordnet. Die Leiterbahnen 8 verbinden beispielsweise die Leuchtdioden 7 miteinander und mit einer elektronischen Ansteuerung. The LED tube lamp 1 has in its lower half, namely the cross-section approximately semicircular filling, a support in the form of a heat sink 2. The heat sink 2 may have, for example, cooling fins. An upper side 3 of the heat sink 2 directed upwards in this view has a recess 4 which is rectangular in cross-section at its center, ie the recess 4 extends in a straight line in a plane perpendicular to the image plane. Introduced into the recess 4 is a LED carrier 5, which is equipped on its upper side or front side 6 with a plurality Leuchtdi ¬ diodes (LEDs) 7 and conductors 8 or occupied. The light-emitting diodes 7 are preferably arranged equidistantly in a row in the longitudinal direction of the LED tube lamp 1. The interconnects 8 connect, for example, the LEDs 7 together and with an electronic control.
Die Leiterbahnen 8 sind von einer Leiterbahnabdeckung 9 aus Glas oder einem glasartigen Material abgedeckt, so dass eine Kriechstrecke K zu den Leuchtdioden 7 mindestens bis zu einem seitlichen Rand der Leiterbahnabdeckung 9, hier angedeutet durch den Abstand K, reicht. The conductor tracks 8 are covered by a conductor track cover 9 made of glass or a glassy material, so that a creepage distance K to the LEDs 7 at least up to a lateral edge of the conductor track cover 9, indicated here by the distance K, extends.
An seiner Rückseite 10 liegt der LED-Träger 6 über eine Lage aus einem Wärmeleitkleber 11 auf einem Boden der Aussparung 4 auf. Der bestückte LED-Träger 5 ist über seine gesamte Länge von einer LED-Abdeckung 12 überwölbt, welche ebenfalls in der Aussparung 4 sitzt, und zwar so, dass sie seitlich gegen einen abgestuften Rand 13 der Aussparung 4 drückt, so dass der abgestufte Rand 13 gleichzeitig einen seitlichen Anschlag für die LED-Abdeckung 12 darstellt. On its rear side 10, the LED carrier 6 rests on a layer of a thermal adhesive 11 on a bottom of the recess 4. The populated LED carrier 5 is arched over its entire length by an LED cover 12, which also in the Recess 4 is seated, in such a way that it presses laterally against a stepped edge 13 of the recess 4, so that the stepped edge 13 simultaneously represents a lateral stop for the LED cover 12.
Die LED-Abdeckung 12 besteht hier aus einem elektrisch isolierenden, lichtdurchlässigen und diffus streuenden Material, so dass die LED-Abdeckung 12 gleichzeitig als elektrische Isolierung und als ein optischer Diffusor dient. Die dem LED- Träger 5 zugewandte Innenseite kann teilweise mittels einer lichtundurchlässigen Blendenschicht 14 bedeckt sein, z.B. einer Metallisierung, so dass Licht von den Leuchtdioden nur durch ein von der Blendenschicht 14 freigelassenes Fenster 15 hindurchläuft . Here, the LED cover 12 consists of an electrically insulating, transparent and diffusely scattering material, so that the LED cover 12 simultaneously serves as electrical insulation and as an optical diffuser. The inner side facing the LED carrier 5 may be partially covered by an opaque diaphragm layer 14, e.g. a metallization, so that light from the LEDs only passes through a released from the aperture layer 14 window 15.
Die LED-Abdeckung 12 kann aus Kunststoff bestehen, hier beispielsweise in Form eines halbkreiszylinderförmigen Kunststoffkörpers realisiert, wobei die LED-Abdeckung 12 hier vor¬ zugsweise selbsttragend und nur geringfügig elastisch biegbar ist. Durch die elastische Biegbarkeit der LED-Abdeckung 12 kann diese beispielsweise beidseitig seitlich eingedrückt und dann in die Aussparung 4 eingesetzt werden, wobei nach einer Beendigung der beidseitigen Krafteinleitung die LED-Abdeckung 12 wieder seitlich zurückfedert und so durch eine Presspas- sung in der Aussparung 4 gehalten werden kann. Um eine noch sicherere Verbindung zwischen der LED-Abdeckung 12 und dem Kühlkörper 2 zu ermöglichen, beispielsweise um ein Ablösen der LED-Abdeckung 12 während eines Transports usw. zu verhindern, ist an einer Stoßkante zwischen der Oberfläche 3 und der LED-Abdeckung 12 eine Klebewulst 17 aufgebracht, z.B. durch Dispensieren eines zunächst flüssigen und dann aushärtenden Klebers . The LED cover 12 may be made of plastic, realized here, for example in the form of a semicircular cylindrical plastic body, wherein the LED cover 12 is here before ¬ preferably self-supporting and only slightly elastic bendable. As a result of the elastic flexibility of the LED cover 12, it can be pressed in laterally on both sides and then inserted into the recess 4, the LED cover 12 springing back laterally after a termination of the two-sided introduction of force, and thus by a press fit in the recess 4 can be held. In order to allow an even more secure connection between the LED cover 12 and the heat sink 2, for example, to prevent detachment of the LED cover 12 during transportation, etc., at a abutting edge between the surface 3 and the LED cover 12 is a Adhesive 17 applied, for example by dispensing a first liquid and then curing adhesive.
Die Oberseite 3 des Kühlkörpers 2 wird als Ganzes von einer (transparenten oder diffus streuenden) Schutzabdeckung 16 überwölbt. Die Schutzabdeckung 16 weist eine im Wesentlichen halbkreiszylinderförmige Querschnittsform auf und setzt be- züglich einer Außenkontur flächenbündig an dem Kühlkörper 2 an. Die Außenkontur des Kühlkörpers 2 und die Außenkontur der Schutzabdeckung 16 bilden zusammen zumindest im Wesentlichen eine zylinderförmige Fläche. Die Schutzabdeckung 16 kann bei- spielsweise mit dem Kühlkörper 2 verklebt sein und beispiels¬ weise in randseitige Längsnuten (o.Abb.) des Kühlkörpers 2, welche als eine Montageausnehmung dienen, eingesteckt sein. Die Schutzabdeckung 16 besteht ebenfalls aus einem elektrisch isolierenden Material und bewirkt, dass der LED-Träger 5 mit den auf seiner Oberseite befindlichen Leuchtdioden 7 und Leiterbahnen 8 zusammen mit der LED-Abdeckung 12 doppelt geschützt ist. Dadurch können insbesondere elektrisch kritische Luftstrecken vermieden werden. Die LED-Röhrenlampe 1 kann unter anderem dadurch hergestellt werden, dass zunächst der Wärmeleitkleber 11 in der Aussparung 4 dispensiert wird. Dann wird der bestückte LED-Träger 5 mit seiner Rückseite 10 auf den Wärmeleitkleber 11 aufgedrückt, und es wird gewartet, bis der Wärmeleitkleber 11 aus- gehärtet ist, so dass der LED-Träger 5 sicher an dem Kühlkörper 2 haftet. In einem folgenden Schritt wird die LED- Abdeckung 12 in die Aussparung 4 eingesetzt und dann durch die Klebewulst 17 mit dem Kühlkörper 2 verklebt. Dann kann die Schutzabdeckung 16 auf den Kühlkörper aufgesetzt und dort befestigt werden. In noch einem weiteren Schritt können die noch offenen Enden der sich bis dahin ergebenden LED- Röhrenlampe 1 mit entsprechenden Kappen zur mechanischen und/oder elektrischen Kontaktierung versehen werden. Bei einem Betrieb der LED-Röhrenlampe 1 strahlen die LEDs 7 Licht durch das Fenster 15 ab, wobei eine annähernd punktför¬ mige Lichtverteilung am Ort der LEDs 7 durch die diffus streuende Eigenschaft der LED-Abdeckung 12 homogenisiert wird. Der durch das Fenster 15 austretende Lichtstrahl läuft weiter durch die Schutzabdeckung 16, wobei die Schutzabde¬ ckung 16 dann, wenn sie auch eine strahlformende Eigenschaft aufweist, beispielsweise durch darin integrierte Linsenberei- che, den durch sie hindurchlaufenden Lichtstrahl nochmals formen, beispielsweise fokussieren oder aufweiten kann. The upper side 3 of the heat sink 2 is overarched as a whole by a (transparent or diffusely scattering) protective cover 16. The protective cover 16 has a substantially semicircular cylindrical cross-sectional shape and sets plus an outer contour flush with the heat sink 2 at. The outer contour of the heat sink 2 and the outer contour of the protective cover 16 together form at least substantially a cylindrical surface. The protective cover 16 can be glued as examples game with the cooling body 2 and, in Example ¬ edge-side longitudinal grooves (o.Abb.) Of the heat sink 2, which serve as a mounting recess, to be inserted. The protective cover 16 is also made of an electrically insulating material and causes the LED carrier 5 is double-protected with the LEDs 7 and printed conductors 8 located on its upper side together with the LED cover 12. As a result, especially electrically critical air gaps can be avoided. The LED tube lamp 1 can be produced inter alia by first dispensing the thermal adhesive 11 in the recess 4. Then the populated LED carrier 5 is pressed with its rear side 10 onto the thermal adhesive 11, and it is waited until the thermal adhesive 11 is cured, so that the LED carrier 5 securely adheres to the heat sink 2. In a following step, the LED cover 12 is inserted into the recess 4 and then glued by the adhesive bead 17 with the heat sink 2. Then, the protective cover 16 can be placed on the heat sink and fastened there. In yet another step, the still open ends of the result up to then resulting LED tube lamp 1 can be provided with corresponding caps for mechanical and / or electrical contact. During operation of the LED tube lamp 1, the LEDs 7 emit light through the window 15, wherein an approximately punktför ¬ mige light distribution at the location of the LEDs 7 is homogenized by the diffusely scattering property of the LED cover 12. The exiting through the window 15 the light beam passes on through the protective cover 16, wherein the Schutzabde ¬ ckung 16 when it also includes a beam-forming property, for example by integrated therein Linsenberei- surface, for example, to focus or widen the light beam passing through it.
Die von den LEDs 7 erzeugte Abwärme wird durch den LED-Träger 5 und den Wärmeleitkleber 11 auf den Kühlkörper 2 übertragen. Dadurch, dass der Wärmeleitkleber 11 einen geringen thermischen Widerstand besitzt und zudem sehr dünn aufgetragen werden kann, kann die Wärme von dem LED-Träger 5 im Wesentlichen ungehindert auf den Kühlkörper 2 übertragen werden. The waste heat generated by the LEDs 7 is transmitted to the heat sink 2 by the LED carrier 5 and the thermal adhesive 11. Due to the fact that the heat-conducting adhesive 11 has a low thermal resistance and, moreover, can be applied very thinly, the heat from the LED carrier 5 can be transmitted to the heat sink 2 substantially unhindered.
Der LED-Träger 5 weist hier vorzugsweise ein Basismaterial aus Keramik (Aluminiumoxid, Aluminiumnitrid usw.) auf, so dass er erstens elektrisch sehr gut isoliert, eine hohe Durchschlagsfestigkeit aufweist, eine hohe Wärmebeständigkeit aufweist, was insbesondere bei einer Auftragung der Leiter¬ bahnabdeckung 9 aus Glas vorteilhaft ist und zudem eine sehr gute thermische Leitfähigkeit aufweist, so dass die Leuchtdi¬ oden 7 sehr effektiv kühlbar sind. Fig.2 zeigt eine LED-Röhrenlampe 21 gemäß einer zweiten Aus¬ führungsform. Im Gegensatz zur LED-Röhrenlampe 1 ist die LED- Abdeckung 22 nun so ausgeführt, dass sie gleichzeitig als die Zwischenlage 27 dient. Dazu besteht die LED-Abdeckung 22 aus einem ursprünglich rechteckigen Blatt (einem Körper, dessen Dicke erheblich geringer ist als seine ebene Ausdehnung) aus einem elektrisch isolierenden, lichtdurchlässigen und diffus streuenden Material, insbesondere Kunststoff. Die LED- Abdeckung 22 wird folgend in einen zusammengerollten Zustand überführt, der hier gezeigt ist, bei dem durch die LED- Abdeckung 22 ein Kontakt- oder Stoßbereich 23 gebildet wird, an dem zwei Bereiche der LED-Abdeckung 22 aufeinanderstoßen. Dabei kann der zusammengerollte Zustand nicht nur durch eine Rollbewegung sondern auch durch jegliche andere Verbiegung des Blatts erreicht werden, beispielsweise durch großflächi- ges Verbiegen entlang einer oder mehrerer Biegelinien. Bei der LED-Röhrenlampe 21 ist die LED-Abdeckung 22 so mon¬ tiert worden, dass zunächst das die LED-Abdeckung 22 bildende Blatt auf den Kühlkörper gelegt wird, so dass es die Ausspa¬ rung 4 überdeckt. Dann wird der LED-Träger 5 mit seiner Rück- seite 10 in die Aussparung 4 eingesetzt und auf den in der Auflage 2 befindlichen Teil der LED-Abdeckung 22 (welche als die Zwischenlage 27 dienen soll) aufgedrückt, z.B. durch Nie¬ derhalter oder andere Befestigungselemente. Da der LED-Träger 5 schmaler ist als die Aussparung 4, verbleibt auf einer Sei- te ein schmaler Abschnitt 24 der LED-Abdeckung 22 frei, und auf der anderen Seite verbleibt ein breiter Abschnitt 25 der LED-Abdeckung 22 frei. Durch den abgestuften Rand 13 der Aussparung 4 werden der schmale Abschnitt 24 und der breite Ab¬ schnitt 25 dort hochgebogen. Der schmale Abschnitt 24 weist somit einen nach schräg oben gerichteten, vorzugsweise aus der Aussparung 4 herausschauenden freien Seitenrand auf. The LED carrier 5 preferably has here a base material made of ceramic (alumina, aluminum nitride, etc.), so that it first electrically very well insulated, has a high dielectric strength, has a high heat resistance, which in particular in a plot of the conductor ¬ track cover 9 is advantageous from glass and also has a very good thermal conductivity, so that the Leuchtdi ¬ oden 7 are very effective coolable. 2 shows a LED fluorescent lamp 21 according to a second ¬ guide die. In contrast to the LED tube lamp 1, the LED cover 22 is now designed so that it serves as the intermediate layer 27 at the same time. For this purpose, the LED cover 22 consists of an originally rectangular sheet (a body whose thickness is considerably smaller than its planar extent) made of an electrically insulating, translucent and diffusely scattering material, in particular plastic. The LED cover 22 is subsequently transferred to a rolled-up state shown here in which a contact or abutting portion 23 is formed by the LED cover 22, on which two portions of the LED cover 22 collide. In this case, the rolled-up state can be achieved not only by a rolling movement but also by any other bending of the sheet, for example by large-scale bending along one or more bending lines. In the LED tube lamp 21, the LED cover 22 has been so mon ¬ advantage that initially the LED cover 22 forming sheet is placed on the heat sink, so that it covers the Ausspa ¬ tion 4. Then, the LED supporter 5 is inserted with its rear side 10 in the recess 4 and (to serve serving as the intermediate layer 27) to the located in the support 2 of the LED cover 22 pressed, for example by Nie ¬ derhalter or other fasteners. Since the LED carrier 5 is narrower than the recess 4, a narrow portion 24 of the LED cover 22 remains free on one side, and on the other side a wide portion 25 of the LED cover 22 remains free. Due to the stepped edge 13 of the recess 4 of the narrow portion 24 and the wide Ab ¬ section 25 are bent up there. The narrow portion 24 thus has an obliquely upwardly directed, preferably out of the recess 4 looking out free side edge.
Als nächstes wird der breite Abschnitt 25 einfach über den bestückten LED-Träger 5 herübergebogen und mit seinem freien Rand an dem freien Rand des schmalen Abschnitts 24 vorbei in eine als Längsnut ausgebildete Montageausnehmung 26 in der Oberfläche 3 des Kühlkörpers 2 eingesteckt. Dabei drückt zu¬ mindest der freie Rand des schmalen Abschnitts 24 gegen den breiten Abschnitt 25 und bildet so einen den LED-Träger 5 in Längsrichtung der LED-Röhrenlampe 21 umschließenden, elektrisch isolierenden Körper. Die Endflächen stehen bis dahin weiterhin offen, können aber geeignet verschlossen werden, beispielsweise durch ein Zusammenziehen oder Zusammenpressen, so dass die LED-Abdeckung 22 für den LED-Träger 5 eine im We- sentlichen (bis beispielsweise auf flächengrößenmäßig ver¬ nachlässigbare Durchführungen für Befestigungselemente oder elektrische Leitungen) allseitig umschlossen wird. Bei der LED-Röhrenlampe 21 wird der Stoßbereich ausschließlich durch den mechanischen Druck des schmalen Abschnitts 24 auf den breiten Abschnitt 25 aufrechterhalten, es ist keine Nachbearbeitung an dem Stoßbereich 23 erforderlich. Die Montageausnehmung 26 und/oder der freie seitliche Rand des breiten Abschnitts 25 können vor einem Einstecken des freien Rands in die Montageausnehmung 26 mit einem Haftmittel versehen werden, um ein unbeabsichtigtes Lösen der LED- Abdeckung 22, 25 aus der Montageausnehmung 26 sicher zu verhindern . Next, the wide portion 25 is simply bent over the populated LED support 5 and inserted with its free edge past the free edge of the narrow portion 24 in a trained as a longitudinal groove mounting recess 26 in the surface 3 of the heat sink 2. Thereby suppressed to ¬ least the free edge of the narrow portion 24 to the wide portion 25 and thus forms an enclosing the LED carrier 5 in the longitudinal direction of the LED lamp tube 21, electrically insulative body. The end surfaces remain open until then, but can be suitably closed, for example by contracting or compressing, so that the LED cover 22 for the LED carrier 5 essentially (up to, for example, surface-size ver ¬ negligible feedthroughs for fasteners or electrical lines) is enclosed on all sides. In the LED tube lamp 21, the impact area is maintained solely by the mechanical pressure of the narrow portion 24 on the wide portion 25, no post-processing on the abutment portion 23 is required. The mounting recess 26 and / or the free lateral edge of the wide portion 25 may be provided prior to insertion of the free edge in the mounting recess 26 with an adhesive to prevent inadvertent release of the LED cover 22, 25 from the mounting recess 26 safely.
Je nachdem, welche mechanischen Eigenschaften die LED- Abdeckung 22 aufweist, insbesondere, ob sie im Wesentlichen rein elastisch verformbar oder auch praktisch plastisch verformbar ist, kann der breite Abschnitt 25 der LED-Abdeckung 22 einfach über den bestückten LED-Träger 5 herübergeführt werden (insbesondere bei einem sich im Wesentlichen elastisch verformenden Blatt, welches vorzugsweise auch selbsttragend ist) , oder der breite Abschnitt 25 kann entlang definierter Biegelinien abschnittsweise plastisch verbogen werden (insbesondere bei einem sich plastisch verbiegenden Blatt) . Diese mechanischen Eigenschaften der LED-Abdeckung 22 lassen sich beispielsweise durch eine Auswahl eines Materials, insbeson- dere Kunststoffs, mit geeigneten mechanischen Bulk- Eigenschaften und/oder durch eine Wahl einer Schichtdicke d einstellen. Dabei kann eine geringere Schichtdicke d zur Ver¬ ringerung eines thermischen Übergangswiderstands zwischen der Rückseite 10 des LED-Trägers 5 und dem Kühlkörper 2 vorteil- haft sein. Vorteilhafterweise ist die Dicke d der LED- Abdeckung 22 nur in dem Bereich, der unter dem LED-Träger angeordnet wird, gegenüber dem die LEDs überdeckenden Bereich reduziert. Dadurch wird eine mechanisch stabile Überdeckung der LEDs wie auch eine gute Wärmeabfuhr gewährleistet. Zur effektiveren Wärmeabfuhr wird es allgemein bevorzugt, dass das Material der LED-Abdeckung 22 thermisch gut wärmeleitfä- hig ist. Depending on which mechanical properties the LED cover 22 has, in particular whether it is substantially purely elastically deformable or also practically plastically deformable, the wide section 25 of the LED cover 22 can be easily brought over the populated LED carrier 5 ( in particular in the case of a substantially elastically deforming blade, which is preferably also self-supporting), or the broad portion 25 can be plastically bent in sections along defined bending lines (in particular in the case of a plastically bending blade). These mechanical properties of the LED cover 22 can be adjusted, for example, by a selection of a material, in particular plastic, with suitable mechanical bulk properties and / or by a choice of a layer thickness d. In this case, a smaller layer thickness d to Ver ¬ ringerung a thermal contact resistance between the back side 10 of the LED substrate 5 and the heat sink 2 advanta- be adhesive. Advantageously, the thickness d of the LED cover 22 is reduced only in the region which is arranged below the LED carrier with respect to the region covering the LEDs. This ensures a mechanically stable overlap of the LEDs as well as a good heat dissipation. For more effective heat dissipation, it is generally preferred that the material of the LED cover 22 is thermally well thermally conductive.
Auch die LED-Abdeckung 22 kann zumindest in ihrem breiten Ab- schnitt 25 mit einer Blendenschicht, insbesondere Metallisie¬ rung, (o. Abb.) ausgerüstet sein. Fig.3 zeigt in einer zu Fig.2 analogen Darstellung einen Ausschnitt einer LED-Röhrenlampe 31 gemäß einer dritten Ausfüh¬ rungsform, wobei die Position des Ausschnitts analog zu dem in Fig.2 gestrichelt eingezeichneten Kreis liegt. Der Aus- schnitt zeigt insbesondere einen Stoßbereich 33 einer LED- Abdeckung 32. Also, the LED cover 22 (Fig. O.) Can be cut at least in their broad base 25 having an aperture layer, in particular metallization ¬ tion, be equipped. 3 shows in a view analogous to Figure 2 a section representation of an LED fluorescent lamp 31 according to a third exporting ¬ approximate shape, wherein the position of the cutout in Figure 2 by dashed lines analogous to the drawn circle lies. In particular, the section shows a joint region 33 of an LED cover 32.
Die LED-Röhrenlampe 31 ist zumindest ähnlich zu der Röhren¬ lampe 21 aufgebaut, außer dass der schmale Abschnitt 34 und der breite Abschnitt 35 in dem Stoßbereich 33 fest miteinander verbunden sind. Dadurch kann die Montageausnehmung 26 entfallen. Die feste Verbindung kann beispielsweise durch ein KunstStofflaserschweißverfahren bewerkstelligt werden. Dazu ist der schmale Abschnitt 34 so schmal, dass er sich voll- ständig in dem Boden der Aussparung 4 des Kühlkörpers 2 be¬ findet, vorzugsweise so, dass sein freier Rand an den abge¬ stuften Rand 13 der Aussparung 4 stößt, so dass eine genaue Positionierung des freien Rands und damit der LED-Abdeckung 32 besonders einfach durchgeführt werden kann. Dadurch liegt der schmale Abschnitt 34 flach auf dem Boden der Aussparung 4 auf, so dass der freie seitliche Rand des breiten Abschnitts 35 einfach ebenfalls in der Aussparung 4 oberhalb des schma¬ len Abschnitts 24 aufgesetzt werden kann, wobei der abgestuf¬ te Rand 13 als ein seitlicher Anschlag dient. Durch ein leichtes Herunterdrücken des breiten Abschnitts 35 bildet sich ein zumindest linienförmiger, vorzugsweise breiter Stoßbereich oder Kontaktbereich, welcher durch einen Laserstrahl L zum Verschweißen der beiden Abschnitte 34, 35 einfach erreichbar ist. Auch dieses Verfahren lässt sich besonders ein- fach durchführen und ergibt auch den Vorteil, dass das Schweißverfahren eine normtechnisch elektrisch dichte Verbindung bildet. The LED fluorescent lamp 31 is at least similar in structure to the tubes ¬ lamp 21 except that the narrow portion 34 and the wide portion 35 is connected firmly to one another in the joint region 33rd As a result, the mounting recess 26 can be omitted. The solid compound can be accomplished, for example, by a plastic fiber welding process. For this purpose, the narrow portion 34 is so narrow that it is completely in the bottom of the recess 4 of the heat sink 2 be ¬ , preferably so that its free edge abuts the abge ¬ stepped edge 13 of the recess 4, so that a Precise positioning of the free edge and thus the LED cover 32 can be carried out very easily. As a result, the narrow portion 34 lies flat on the bottom of the recess 4, so that the free lateral edge of the wide portion 35 can also be easily placed in the recess 4 above the schma ¬ len section 24, wherein the graduf ¬ te edge 13 as a lateral stop is used. By a slight depression of the wide portion 35, an at least line-shaped, preferably broad impact area or contact area is formed, which is easily accessible by a laser beam L for welding the two sections 34, 35. This method can also be carried out particularly easily and also has the advantage that the welding method forms a connection that is electrically sealed in terms of standard technology.
Selbstverständlich ist die vorliegende Erfindung nicht auf die gezeigten Ausführungsbeispiele beschränkt. So ist die LED-Leuchtvorrichtung nicht auf eine Verwendung mit LED-Röhrenlampen beschränkt. Es können vielmehr auch anders ausgestaltete LED-Lampen die beschriebene Erfindung nut¬ zen bzw. damit aufgebaut sein. Darüber hinaus ist die Erfin- dung nicht auf eine Verwendung mit einer Lampe beschränkt, sondern kann beispielsweise auch LED-Module und LED-Leuchten umfassen. Beispielsweise kann der Kühlkörper anstelle des ge¬ zeigten dedizierten Kühlkörpers einer LED-Röhrenlampe auch ein Teil einer LED-Leuchte sein, dies kann insbesondere be- deuten, dass sich die LEDs 7 nicht einfach standardisiert austauschen lassen, was jedoch in Anbetracht der hohen Lebensdauern der LEDs 7 kein wesentliches Problem sein mag. Beispielsweise mag die Leuchte eine Tischleuchte, Wandleuchte oder Pultleuchte sein, welche ebenfalls eine zylindrische Grundform aufweisen können. Of course, the present invention is not limited to the embodiments shown. Thus, the LED lighting device is not limited to use with LED tube lamps. It can rather the described invention be constructed nut ¬ zen and thus also differently designed LED lamps. In addition, the invention is not limited to use with a lamp, but may include, for example, LED modules and LED lights. For example, the heat sink instead of ge ¬ showed dedicated heatsink a LED tube lamp also be a part of an LED luminaire, this particular point loading that 7 does not just let the LEDs replace standardized, which, however, in view of the long lifetimes LEDs 7 may not be a significant problem. For example, the lamp may be a table lamp, wall lamp or desk lamp, which may also have a cylindrical basic shape.
Allgemein ist die Erfindung nicht auf längliche, z.B. zylinderförmige, Leuchtvorrichtungen beschränkt, sondern kann auch jede andere Form annehmen, z.B. mit rotationssymmetrischen Abdeckungen, solange nur die doppelte Abdeckung mit der LED- Abdeckung und der Schutzabdeckung über den LEDs umsetzbar ist . Generally, the invention is not intended to be elongate, e.g. cylindrical, lighting devices limited, but may also take any other form, e.g. with rotationally symmetrical covers, as long as only the double cover with the LED cover and the protective cover over the LEDs can be implemented.
Das Material der LED-Abdeckung kann z.B. PC, ABS und/oder PMMA aufweisen. The material of the LED cover can have, for example, PC, ABS and / or PMMA.
