Abstract

The invention relates to a compact lamp with adapter consisting of a gas discharge vessel (1) with electrode terminals (2) and having a plug-in adapter with counter-contacts (3), in which there is an electronic ballast (4). The contacts (3) of the adapter take the form of flat springs electrically connected to the output terminals (2) of the ballast (4) which contact under spring pressure when the adapter and the gas discharge vessel (1) are plugged together. To improve insulation, the flat springs (3) are fitted in substantially axially extending chambers (13) in the adapter housing.

Description

Compact lamp with adapter

Gas discharge lamps require a ballast to limit the current and most of the compact lamps on the market such ballast are integrated in a common housing with the Gasentladungsgefä3.

Since the gas discharge AESS compared to the ballast has a relatively short life, it is best to build these two parts separately and to connect both parts with a plug connection.

Such a connector requires at least two, usually four electrical connections to be made as small and inexpensive.

Object of the invention is to describe a particularly simple design which is suitable for the smallest space and lowest total cost, especially for a vollauto¬ matic assembly.

To achieve the object, the invention is characterized by the technical teaching of claim 1.

An essential feature of the invention, since / 3, each flat spring is disposed in a respective extending substantially in the axial direction in the housing chamber of the adapter and is thus protected against accidental electrical contacts on the part of the circuit board of the ballast. So the chamber walls protect the flat springs against the electronic components of the ballast.

The invention thus proposes an attachable adapter, which contains the electronic ballast and flat springs as counter-contacts for the Elektrodenan- εchlüsse of the gas discharge äßes which the fäßes both resiliently with the electrodes Anschlussen of Gasentladungsge-, but the device also to the output Anschlussen of the ballast, a compound produce.

Moreover, such flat springs can be designed such as / 3 they form fit with the circuits of the Elektrodenan¬ Gasentladungsgefä / 3es rest.

A particular advantage of the inventive Ausge¬ staltung these leaf springs is that, as / 3 are inserted into the housing of the adapter after the loading of the electronic ballast.

A particularly simple contact between the Connection wires, the ballast and the leaf spring takes place in that the connecting wire extends in each case in a chamber and that an electrical contact with this An¬ is prepared circuiting wire after the insertion of the flat spring in the chamber.

It therefore requires no soldering, plug or clamp connection to make such contact.

Of course, however, the invention also encompasses such soldering, plug and socket connections and is not limited to the above embodiment.

Another essential feature of the invention that is arranged in the substantially flat circuit board in the axial direction in the housing and carries the components of the ballast. This is a very raum¬ saving construction is achieved and the total given Bauhöhe- of the adapter is substantially reduced. In this case, it is preferred if the chambers for receiving the flat springs are arranged on both sides of the circuit board in the housing, as this gives the greatest possible distance between the chambers and thus good insulation distances.

Incidentally, it is preferable if the housing of the adapter is designed in two parts and consists of a Gehäuse¬ lower part, as well as a releasably connected to this upper housing part. This results in a particularly simple manufacture and easy installation.

It is preferred here for the connection of housing upper to the lower housing part, a locking connection between said two parts.

The invention object of the present invention arises not only from the subject of the individual patent claims

εprüche, but also from the combination of the individual patent claims. All in the documents, including the summary, disclosed details and characteristics, in particular the spatial design shown in the drawings as essential to the invention claimed, as far as they individually or in combination over the prior art are new.

In the following the invention is explained in detail with reference to only one embodiment illustrative drawings. Here are evident from the drawings and their description

more erfindungεweεentliche features and advantages of the invention Extend the features and advantages of the invention produced.

Show it:

1 shows schematically a section through an adapter;

2 shows in an exploded view -unterteil the adapter housing top and;

3 shows a gas discharge vessel with electrode terminals in side view;

4 shows the top view of the open housing lower part;

5 shows a modified embodiment of a

Adapter in comparison with FIG. 4

Figures 1 to 5 schematically show an exemplary embodiment of the inventive concept.

Figure 1 firstly shows an adapter, for example for connection to the mains with a screw thread (7) in a normal standard version E 27 can be screwed in order to connect to the mains. The thread (7) is provided with a housing upper part (9) verbun¬ to which can be connected to a housing lower part (10). This housing is made of insulating aterial contains an electronic ballast (4), which, for example, for ease of mounting on a printed circuit board (8) is constructed. 3 shows a gas discharge vessel (1) having its electrode terminals (2) in a base (11) is shown schematically.

said flat springs (3) in the housing lower part (10) are now In the present invention arranged such that they produce on the one hand an electrical connection to the output Anschlussen (5) and (6) of the electronic ballast, but also the other hand, when plugging in the Gasentladungsge- fäßes (1 ) lie resiliently against the electrodes Anschlussen (2) and thus establish the electrical connection. In Figure 1, the position of a electrode lead (2) is shown after being plugged and is designated (12) on the right side.

In Figure 4, the still open housing lower part (10) with inserted ballast (4) and the losing Ausgangsan¬ (5) and (6) is shown. In this example, the output terminals (5) and (6) are shown as wires, which extend into the chambers (13). The flat springs (3) are not used in Figure 4, so that one can still see the slots (14), can be eingschoben in the later, the electrode terminals (2).

In figure 2 is shown how the housing upper part (9) is not on the housing lower part (10) is seated, the printed circuit board (8) to the electronic ballast device (4), however, is included in the lower housing part (10) inserted. Only after the flat springs (3) in the

Chambers (13) are inserted, the upper housing part (9) is placed, as shown in FIG. 1

The chambers (4) further have the advantage that elec- trical components of the ballast (4) are electrically disconnected from the spring contacts (3).

The embodiment may of course be varied in many ways. 5 shows, for example, "an embodiment of a round adapter in a symmetrical embodiment, but of course also a non-symmetrical arrangement of the contacts and the slots (14) can be provided to the vessel for example to avoid confusion when inserting the Geasentladungs-.

In Figure 1, also hold-down (15) are shown which have the task in the lower housing part (10) flat springs (3) inserted to prevent it from moving up.

The example shows the extreme simplicity of the flat spring contacts that do not require a complicated die, still a soldered or welded connection. The insertion of the flat springs (3) is possible even with an automatic assembling by a simple robotic assembly.

The embodiment mentioned is by no means intended to be limiting. It merely serves to ein¬ simpler explanation -des inventive concept, and can be adapted in the form of any desired spatial and functional moderate requirements. DRAWING LEGEND
