LED-LAMPE IN KERZENFORMLED LAMP IN CANDLE SHAPE
[0001] Die Erfindung bezieht sich auf eine LED-Lampe in Kerzenform, mit einem an einem Kühlkörper angeschlossenen Lampenkolben, in dem wenigstens ein mit dem Kühlkörper in Verbindung stehender LED-Chip untergebracht ist.The invention relates to a LED lamp in candle shape, with a lamp body connected to a heat sink, in which at least one standing with the heat sink in connection LED chip is housed.
[0002] Bekannte Lampen mit dieser Bauart weisen die herkömmliche Kerzen(flammen)form auf, bei der sich im „Dochtbereich" ein Anschlussgewinde befindet. Die Lichtabstrahlung erfolgt dabei von der Oberfläche des Lampenkolbens, ähnlich wie bei matten Glühbirnen. Der ästhetische Eindruck einer klaren Kerzenglühbirne, der insbesondere bei Lustern erwünscht ist, kann mit diesen somit nicht erreicht werden.Known lamps of this type have the conventional candles (flames) form, in which in the "Wick area". a connection thread is located. The light emission takes place from the surface of the lamp bulb, similar to dimmed bulbs. The aesthetic impression of a clear candle light bulb, which is particularly desirable in Lustern, can not be achieved with these thus.
[0003] Ziel der Erfindung ist eine LED-Lampe in Kerzenform, die dem äußeren Aussehen einer klaren Lusterkerze entspricht. Dieses Ziel wird erfindungsgemäß dadurch erreicht, dass an dem LED -Chip (1) ein Lichtleiter (2) angesetzt und der Kühlkörper (4) als Kerzenhülse ausgeführt ist.The aim of the invention is a LED lamp in candle shape, which corresponds to the external appearance of a clear chandelier candle. This object is inventively achieved in that on the LED chip (1) a light guide (2) recognized and the heat sink (4) is designed as a candle sleeve.
[0004] Die Formgebung des Lichtleiters kann beliebig erfolgen und jedenfalls so beschaffen sein, dass der Leuchteindruck einer herkömmlichen Glühwendel vermittelt wird. Durch die Ausgestaltung des Kühlkörpers als den optischen Eindruck des Wachskörpers einer Kerze vermittelnde Kerzenhülse wird eine wesentlich effektivere Kühlung des LED-Chips bewirkt, als dies mit den bisher bekannten, relativ kleinen, noch im längeren Kolbenbereich befindlichen Kühlkörpern möglich ist. Dadurch können stärkere beziehungsweise mehrere LED-Chips zum Einsatz kommen als dies derzeit der Fall ist. Der elektrische Anschluss der erfindungsgemäßen LED-Lampe kann in herkömmlicher Weise erfolgen, z.B. mit Schraubverbindung, Steckverbindung usw. Im Inneren der Kerzenhülse können außerdem Vorschaltgeräte, Steuereinrichtungen etc. untergebracht werden.The shape of the light guide can be arbitrary and in any case be such that the light impression of a conventional filament is mediated. Due to the design of the heat sink as the optical impression of the wax body of a candle mediating candle sleeve is a much more effective cooling of the LED chip causes, as is possible with the previously known, relatively small, still in the longer piston area located heat sinks. As a result, stronger or more LED chips can be used than is currently the case. The electrical connection of the LED lamp according to the invention can be carried out in a conventional manner, e.g. with screw connection, plug connection, etc. In the interior of the plug sleeve also ballasts, control devices, etc. can be accommodated.
[0005] Um den Leuchteffekt zu verstärken beziehungsweise variantenreich gestalten zu können, ist es von Vorteil, wenn der Lichtleiter (2) und der Lampenkolben (3) einstückig (9) ausgeführt sind. In diesem Fall kann nämlich ein Kombinationseffekt der Lichtabstrahlung seitens des zum Beispiel eine Glühwendel simulierenden Lichtleiters und des beliebig gestaltbaren Lampenkolbens erreicht werden.In order to enhance the lighting effect or to make varied, it is advantageous if the light guide (2) and the lamp bulb (3) are made in one piece (9). In this case, namely, a combination effect of the light emission can be achieved by the example of an incandescent helix simulating light guide and the lamp bulb of any design.
[0006] Weiters kann es zweckmäßig sein, wenn der Lichtleiter (2) und/oder der Lampenkolben (3) wenigstens an einer vorbestimmten Stelle eine Verspiegelung (10) aufweist. Dadurch kann eine gewünschte Verteilung des Lichtstroms erhalten werden, zum Beispiel mit einer Vorzugsrichtung und - bei mehreren LED-Chips -eventuell kombiniert mit individuellen Dimmen Einzelner LED-Chips.Furthermore, it may be expedient if the light guide (2) and / or the lamp bulb (3) at least at a predetermined location has a reflective coating (10). Thereby, a desired distribution of the luminous flux can be obtained, for example, with a preferred direction and - in the case of several LED chips - possibly combined with individual dimming of individual LED chips.
[0007] Die Erfindung wird im Folgenden an Hand von in der Zeichnung veranschaulichten Ausführungsbeispielen näher erläutert. Es zeigen die Fig. 1 bis 4 in schematischer Darstellung verschiedener Ausführungsformen der erfindungsgemäßen LED-Lampe und Fig. 5 einen Anschnitt eines Lichtleiters mit Verspiegelung.The invention will be explained in more detail below with reference to embodiments illustrated in the drawings. 1 to 4 show a schematic representation of various embodiments of the LED lamp according to the invention and Fig. 5 shows a section of a light guide with mirror coating.
[0008] Die erfindungsgemäße LED-Lampe gemäß Fig. 1 weist einen LED-Chip 1 und einen an diesen angeschlossenen Lichtleiters 2 auf, die sich in einem transparenten Lampenkolben 3 befinden, der mit einem Kühlkörper 4 in Form einer Kerzenhülse in Verbindung steht. Weiters sind ein nicht näher spezifizierter elektrischer Anschluss 5 für den LED-Chip 1 sowie eine beliebige mechanische Befestigung 6 für die Lampe vorgesehen. Beim Einschalten der Lampe überträgt der LED-Chip 1 das Licht in den Lichtleiter 2, der dieses durch den Lampenkolben abstrahlt.The LED lamp according to the invention shown in FIG. 1 has an LED chip 1 and a light guide 2 connected to these, which are located in a transparent lamp bulb 3, which is in communication with a heat sink 4 in the form of a candle sleeve. Furthermore, an unspecified electrical connection 5 for the LED chip 1 and any mechanical attachment 6 for the lamp are provided. When the lamp is switched on, the LED chip 1 transmits the light into the light guide 2, which radiates it through the lamp bulb.
[0009] Die Ausführungsform der Fig. 2 unterscheidet sich von jener der Fig. 1 dadurch, dass in der Kerzenhülse 4 z.B. ein Vorschaltgerät 7 mit Gewindesockel 8 untergebracht ist. 1/4The embodiment of Fig. 2 differs from that of Fig. 1 in that in the candle sleeve 4, e.g. a ballast 7 with threaded socket 8 is housed. 1.4
