Description
12Z839~
PHI 21.149 l 28.11.1983 Adapter.
The invention relates to an adapter for arranging a discharge lamp with a base on one side in a holder suitable to receive lamp bases of incandescent lamps, which adapter comprises a housing which accomo-dates a holder for receiving the discharge lamp and which is provided not only with an incandescent lamp base, but also with connection means for an electrical stabilization ballast, on the side wall with the aid of which the ballast is electrically connected both to the lamp base and to the holder for the discharge lamp. Such an adapter is known from German Patent Specification 837,893.
lo It is proposed in this Patent Specification to accommodate, when a discharge lamp should be arranged in an incandescent lamp holder, the discharge lamp in a holder in an adapter which is provided with an incandescent lamp base (such as an Edison lamp base). The stabilization ballast required for the operation of the lamp is in the known device connected to the adapter by means of a connection cable manufactured specially for this purpose. A special opening is provided in the side wall of the housing of the adapter for receiving the end of the cable.
When the ballast is connected, the electrical connection between the in-candescent lamp base and the base of the discharge lamp arranged in the holder is then established at the same time. Such a construction has the disadvantage that a special space has to be reserved in or near the luminary for the ballast. This requires an additional amount of space and often special means. Moreover, the use of the loose connection cable is annoying for a user.
The invention has for its object to provide an adapter which obviates the aforementioned disadvantages.
For this purpose, according to the invention, an adapter of the kind mentioned in the opening paragraph is characterized in that the housing of the adapter is provided with means for mechanically detachably securing the ballast, which means are rotatable with respect to the in-candescent lamp base of the adapter.
In an adapter according to the invention, the stabilization ballast can be directly secured to the side wall of the housing (which ~228391 PHI 21.149 2 28.11.1983 preferably consists of synthetic material). The use of a loose cable for establishing the connection between these two parts is avoided.
No special accommodation for the ballast is required in or near the luminary. The overall length of the lamp with the ballast and the adapter is comparatively small.
nut to the fact that the connection means for securing the ballast are rotatable with respect to the incandescent lamp base of the adapter, the adapter with the ballast can be also arranged in a holder which is present in a luminary one wall of which is located lo in the immediate proximity of this holder. In fact, after the adapter has been arranged in the incandescent lamp holder, the user rotates the said means into such a position with respect to the base that the ballast can ye secured to the adapter, for example, on a side remote from the wall. The electrical connection is then established at the same time.
In a preferred embodiment of an adapter according to the in-mention, at least the wall of the housing of the adapter is rotatable with respect to the incandescent lamp base. For example, the side wall of the housing is provided with sleeves arranged to co-operate with electrical plug-in members of the ballast.
The ballast and the housing are secured according to one embodiment by means of a dovetail connection between the side wall of the housing and the outer wall of an envelope which accomoda~es the ballast. The ballast can then be slipped by a user onto the housing in a simple manner.
The invention can be used for discharge lamps with a base on one side, especially low-pressure mercury vapor discharge lamps, as described inter aria in German Offenlegungsschrift 3121077 (PUN 9764).
Such lamps are provided with a lamp base which can be inserted into a special holder. A starter is also incorporated in the lamp base of the said discharge lap. Since these lamps cannot be screwed into a holder for Edison lamp bases without further expedients, an adapter according to the invention has proved to be very suitable.
The invention will now be described more fully with reference to a drawing, which shows an embodiment of the adapter according to the invention. In the drawing:
Figure 1 is an elevation of the adapter with a ballast situated in an envelope, PHI 21.149 3 28.11.1983 Figure 2 shows a circuit diagram of the electric wiring in the housing of the adapter and Figure 3 shows, partly in sectional view and partly in Elena-lion, the adapter at the area of the transition between the housing 5 and the incandescent lamp base.
In Figure 1, reference numeral 1 denotes the adapter. It come proses a housing 2 of synthetic material which accommodates a holder 3 suitable to receive the base of a low-pressure mercury vapor discharge lamp with a base on one side. Such a lamp with an associated holder is 10 described inter aria in DYES 3121077 mentioned earlier. The housing 2 further has at its end an Edison lamp base 4 (for example, an E 27 cap).
However, the use of a bayonet base is alternatively possible. Thus, the adapter with E-27 cap can be screwed into a holder for incandescent lamps. The housing 2 is rotatable with respect to this lamp base 4 (see 15 Fig. 3). Connection means for detachably securing an electrical stabile-ration ballast are provided on the side wall of the housing. This ballast is present in an envelope 5 of synthetic material. The envelope is shaped so that it can be slipped onto the housing by means of a projecting wall portion 6 in the side wall of the housing 2. In this case, a dovetail 20 connection is formed by the profile 7 of the wall portion 6 and the edge 8 of the envelope 5 co-operating with it. The envelope 5 is provided with electrically conducting plug-in members g and 10 arranged to co-operate with sleeves which are located in the upper part of the wall portion 6. These sleeves are not visible in the drawing. If now the 25 envelope 5 is secured on the wall portion 6 of the housing 2 by a user, an electrical connection is established between the lamp holder 3, the ballast and the base 4, which is shown diagrammatically in Fig. 2.
In this Figure, the ballast is shown in the form of a coil (11), which is located in the envelope 5 (shown in dotted lines).
30 The two electrical connection terminals 9 and 10 co-operate with sleeves pa and aye in the housing. The sleeve aye is electrically connected to an electrical conductor 3b in the holder 3 for the discharge lamp. The sleeve pa is connected to the conductor pa in the cap 4; the conductor pa is connected to the conductor 4b, likewise located in the cap. The 35 mains voltage is applied between pa and 4b.
In Fig. 3, the housing of the adapter is again designated by reference numeral 2 and the Edison lamp base by reference numeral 4.
This lamp base is secured to a disk-shaped wall portion 12 with an upright lZ2839~
Pi 21.149 4 28.11.1983 edge, which engages a circular groove 13 on the lower side of the housing

In Figure 1, reference numeral 1 denotes the adapter. It come proses a housing 2 of synthetic material which accommodates a holder 3 suitable to receive the base of a low-pressure mercury vapor discharge lamp with a base on one side. Such a lamp with an associated holder is 10 described inter aria in DYES 3121077 mentioned earlier. The housing 2 further has at its end an Edison lamp base 4 (for example, an E 27 cap).
However, the use of a bayonet base is alternatively possible. Thus, the adapter with E-27 cap can be screwed into a holder for incandescent lamps.

Connection means for detachably securing an electrical stabile-ration ballast are provided on the side wall of the housing. This ballast is present in an envelope 5 of synthetic material. The envelope is shaped so that it can be slipped onto the housing by means of a projecting wall portion 6 in the side wall of the housing 2. In this case, a dovetail 20 connection is formed by the profile 7 of the wall portion 6 and the edge 8 of the envelope 5 co-operating with it.

30 The two electrical connection terminals 9 and 10 co-operate with sleeves pa and aye in the housing. The sleeve aye is electrically connected to an electrical conductor 3b in the holder 3 for the discharge lamp. The sleeve pa is connected to the conductor pa in the cap 4; the conductor pa is connected to the conductor 4b, likewise located in the cap. The 35 mains voltage is applied between pa and 4b.
In Fig. 3, the housing of the adapter is again designated by reference numeral 2 and the Edison lamp base by reference numeral 4.
This lamp base is secured to a disk-shaped wall portion 12 with an upright lZ2839~
Pi 21.149 4 28.11.1983 edge, which engages a circular groove 13 on the lower side of the housing
2. Thus, it is achieved that the housing 2 is rotatable with respect to the wall portion 12 with the lamp base 4. By means of measures known per so, a rotation of the wall portion 12 through, for example, less than 360 is obtained. It is alternatively possible to obtain a rotation through the full range of 360, whereby special sliding contacts for the electrical supply wires 14 and 15 can be provided on the inner wall of the housing 2.
In the embodiment shown, the housing is in the form of a cute lo and the wall consists of synthetic material, for example polycar~onate.
The ballast envelope also consists of the same synthetic material. The disk-shaped wall portion 12 is likewise made of the said synthetic material. In a special embodiment, the wall portion 12 is frictionally cry I
~-~ rotatable in the Cyril groove 13.
