Description

Die Erfindung betrifft einen Leuchtkörper mit einem Lampenkopf und einem damit beweglich verbundenen Lampensockel gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a luminous element with a lamp head and a lamp base movably connected thereto according to the preamble of claim 1.

Täglich werden weltweit Millionen Leuchtkörper in den Müll geworfen, obwohl diese teilweise noch in Ordnung sind oder zumindest eine Komponente (Netzteil, Leuchte, etc.) noch funktionell ist. Ein besonders großes Problem stellen in dieser Hinsicht Leuchtstofflampen dar, da diese toxische Stoffe beinhalten.Every day, millions of lights are thrown in the garbage worldwide, although some of them are still in order or at least one component (power supply unit, lamp, etc.) is still functional. Fluorescent lamps pose a particularly big problem in this regard, as they contain toxic substances.

Es ist deshalb aus dem Stand der Technik bekannt, Lampenkopf und Lampensockel eines Leuchtkörpers derart auszuführen, dass sie voneinander getrennt werden können. Dies hat den Vorteil, dass bei Defekt eines Teils im Lampenkopf nur dieser ausgetauscht werden muss, während der Lampensockel weiterverwendet werden kann.It is therefore known from the prior art to design the lamp head and lamp base of a luminous element in such a way that they can be separated from one another. This has the advantage that if a part in the lamp head is defective, only this part needs to be replaced, while the lamp base can continue to be used.

Auch sind aus dem Stand der Technik Leuchtkörper bekannt, die umschaltbare Leistungen oder Leuchtfarben aufweisen, wobei die Umschaltung in der Regel durch ein Bedienelement am Leuchtkörper erfolgt. Ein derartiges Bedienelement am Leuchtkörper ist jedoch schwierig zu bedienen und meist auch aus ästhetischen Gründen unerwünscht.Luminous bodies are also known from the prior art which have switchable powers or luminous colors, the switching usually being carried out by an operating element on the luminous body. However, such an operating element on the luminous element is difficult to operate and mostly undesirable for aesthetic reasons as well.

Verschiedene Leuchtkörper sind aus der WO 2012/168860A2 , WO 2012/168831 A2 , WO 2012/148384 A1 , DE 10 2012 207188 A1 , EP 1 348 902A1 und DE 10 2012 207190 A1 bekannt.Different filaments are from the WO 2012/168860A2 , WO 2012/168831 A2 , WO 2012/148384 A1 , DE 10 2012 207188 A1 , EP 1 348 902 A1 and DE 10 2012 207190 A1 known.

Die Aufgabe der vorliegenden Erfindung besteht darin, diese bekannten Leuchtkörper in ihrer Bedienbarkeit zu verbessern und weiter auszubilden, um einen ästhetisch ansprechenden Leuchtkörper zu realisieren, der dennoch die bekannte Funktionalität realisiert und wirtschaftlich in seiner Herstellung und Benutzung ist.The object of the present invention is to improve the operability of these known luminous bodies and to develop them further in order to realize an aesthetically pleasing luminous body which nevertheless realizes the known functionality and is economical in its manufacture and use.

Die Aufgabe wird erfindungsgemäß mit einem eingangs genannten Leuchtkörper mit den Merkmalen des Kennzeichens des Anspruchs 1 gelöst.According to the invention, the object is achieved with a luminous element mentioned at the beginning with the features of the characterizing part of claim 1.

Es kann insbesondere vorgesehen sein, dass Lampenkopf und Lampensockel durch eine Steckverbindung lösbar verbunden sind, wobei die Steckverbindung in einer ersten Stellung und zumindest einer zweiten Stellung fixierbar ist, wobei in der ersten Stellung ein erster elektrischer Betriebszustand hergestellt wird, und in der zumindest einen zweiten Stellung ein zweiter elektrischer Betriebszustand hergestellt wird.It can be provided in particular that the lamp head and lamp base are releasably connected by a plug connection, the plug connection in a first position and at least one second position can be fixed, a first electrical operating state being established in the first position and a second electrical operating state being established in the at least one second position.

Durch die erfindungsgemäße Steckverbindung kann der Lampenkopf in zwei unterschiedlichen Stellungen am Lampensockel fixiert werden. Die beiden Stellungen unterscheiden sich in ihrem elektrischen Betriebszustand, sodass der elektrische Betriebszustand des Leuchtkörpers beim Fixieren des Lampenkopfs am Lampensockel durch den Benutzer ausgewählt werden kann. Dadurch wird erreicht, dass am Leuchtkörper kein Bedienelement vorgesehen werden muss, was sowohl die Herstellungskosten reduziert, als auch die ästhetische Erscheinung des Leuchtkörpers verbessert.The plug connection according to the invention allows the lamp head to be fixed in two different positions on the lamp base. The two positions differ in their electrical operating state, so that the electrical operating state of the luminous element can be selected by the user when the lamp head is fixed to the lamp base. This means that no operating element has to be provided on the luminous element, which both reduces the production costs and improves the aesthetic appearance of the luminous element.

Erfindungsgemäß ist eine dritte Stellung vorgesehen, in der der Lampenkopf nicht am Lampensockel fixiert ist, sondern auf den Lampensockel aufgesetzt und von ihm getrennt werden kann.According to the invention, a third position is provided in which the lamp head is not fixed on the lamp base, but can be placed on the lamp base and separated from it.

Es kann vorgesehen sein, dass die zumindest zwei Verschlusselemente und die korrespondierenden zumindest zwei Ausnehmungen jeweils in einer Ebene winkelig zueinander angeordnet sind, wobei der Winkel ungleich 180° ist, sodass ein Einsetzen der Verschlusselemente in die Aufnahmeabschnitte nur in einer einzigen Position möglich ist. Der Winkel kann insbesondere etwa 154 "betragen.It can be provided that the at least two closure elements and the corresponding at least two recesses are each arranged at an angle to one another in one plane, the angle not being 180 °, so that the closure elements can only be inserted into the receiving sections in a single position.

Es kann vorgesehen sein, dass am Lampenkopf ein Zentrierstift vorgesehen ist, der zum Eingriff in eine Zentrieröffnung am Lampensockel ausgeführt ist, um eine geführte Verbindung des Lampenkopfes mit dem Lampensockel zu ermöglichen.Provision can be made for a centering pin to be provided on the lamp head which is designed to engage in a centering opening on the lamp base in order to enable a guided connection of the lamp head to the lamp base.

Es kann vorgesehen sein, dass die Verschlusselemente im eingerasteten Zustand des Bajonettverschlusses mit elektrischen oder elektronischen Komponenten im Lampenkopf und/oder Lampensockel in Verbindung stehen.Provision can be made for the closure elements to be connected to electrical or electronic components in the lamp head and / or lamp base when the bayonet catch is engaged.

Es kann vorgesehen sein, dass die Steckverbindung zumindest teilweise im Inneren eines am Lampensockel angeordneten Kupplungsteils und/oder einer Abdeckhülse angeordnet ist.It can be provided that the plug connection is arranged at least partially in the interior of a coupling part arranged on the lamp base and / or a cover sleeve.

Es kann vorgesehen sein, dass am Lampenkopf, vorzugsweise an einem Kühlkörper, zumindest eine erste Markierung sowie am Kupplungsteil zumindest eine korrespondierende zweite Markierung vorgesehen ist, um die Position der Steckverbindung und den entsprechenden Betriebszustand des Leuchtkörpers anzuzeigen.It can be provided that at least one first marking is provided on the lamp head, preferably on a heat sink, and at least one corresponding second marking is provided on the coupling part in order to indicate the position of the plug connection and the corresponding operating state of the luminous element.
