"Holder for curved fluorescent lamps"

To attach fluorescent lamps are made "known glass and its dimensions can be observed only in relatively large tolerances. This is especially true when bent fluorescent lamps. It is therefore difficult 'uorescent lamps these ^L, in particular lamp the curved fluorescent so that they can easily ausgeweshselt can be made, whereby it must be taken into account that a good contact is made on the power supply pins, which are in one plane

To overcome these difficulties is the purpose of this innovation, whose essence is mainly to be found in the fact that the tolerances in the length of the contact pins 9 by resilient contacts 6 in length of the curved glass tube by compression springs 5, which at the same time Hold the fluorescent lamp 1 firmly after inserting it and keep a distance the contacts 9 by corresponding elongated holes 8, which the contact pins 9 record, be balanced. It does not matter whether the retaining rings 7 are attached to the bend at the outermost end of the glass tube or at another suitable location, e.g. to the cross brace 13 which connects the base 10.

In the drawing, Fig. 1 and Fig. 2 show an embodiment. Fig. 1 shows the front view, partly in section and partly in the View, Fig. 2 shows the side view. The arm 2, which can also consist of several parts, is directly or with the housing 3 indirectly rigidly connected and has a suitable one at its outlet Bracket 7 to hold the glass tube of the fluorescent lamp 1 »The Contact holder 4 is slidably housed in the housing and is by & h one or more springs 5, the coil springs or Leaf springs can be held against a suitable stop 12 · The contact holder 4 is made of a suitable material and takes the resilient contacts 6, he has elongated holes 8 for inserting the contact pins 9 of the fluorescent lamp 1, he also has a Collar or a suitable device to facilitate the introduction of the contact pins 9 into the holes 8.

The insertion of the curved fluorescent lamp 1 is relatively easy with the help of this salter. She will be with the contacts 9 inserted into the elongated or correspondingly large holes 8, the are designed so that the tolerances of the distance of the contact pins 9, with the collar of removal or a suitable device facilitating insertion, then it will printed against the contact holder 4, the contact pins 9 against the resilient contacts 6 press, -these give in and equalize

Claims (2)

Tolerance in the length of the contact pins 9, a wall-free contact being made. The base 10 with the contact pins then lie against the contact holder 4, the springs 5 give way so that the fluorescent tubes can be inserted into the holder 7 of the arm 2, the tolerances in the length of the lamp st off lamp by the corresponding stroke of the contact holder 4 are compensated. The fluorescent lamp is pressed resiliently against the holder 7 and is fixed in this way and can be removed from the lamp in the same way. In order to avoid lateral displacement, a cross bar 11 or the like can be attached. Protection requirements 1.) Holder for curved fluorescent lamps, characterized in that that the drawn fluorescent lamp 1 of one or more arms 2 with a suitable holder 7, which is connected to the housing 3 direki or indirectly firmly connected, in which there is the spring-loaded Koi clock holder 4 "is held. 2.) Housing 3 with contact holder 4 according to claim characterized in that that the contact holder 4 receives the resilient contacts β and that he by means of one or more springs 5 against the stops 12 is held.
