  LAMPE A LUMINESCENCE.

  
Les lampes à luminescence connues de petite dimension présentent sur leur bulbe en verre contenant les électrodes, un socle, qui porte en tant qu'éléments de contact un élément de contact latéral annulaire et à leur surface frontale un élément de contact de base. L'élément de contact latéral annulaire et l'élément de contact de base sont maintenus à distance l'un de l'autre par une masse de remplissage. Ce type de construction augmente la longueur axiale de la lampe à luminescence. Dans les lampes à luminescence connues il faut également des jonctions supplémentaires aux fils d'électrodes et aux éléments de contact du socle.

  
L'invention se rapporte à une lampe à luminescence, qui est caractérisée par une fabrication et un assemblage particulièrement simples. Suivant l'invention le bulbe en verre contenant les électrodes est monté dans un corps isolant en forme d'enveloppe. On a prévu sur l'enveloppe du corps isolant des éléments de contact de socle constitués par des fils d'électrodes ou des fils d'amenée aux résistances auxiliaires. Grâce à cette construction la lampe à luminescence peut être montée dans des instruments électriques d'une manière simple en tant qu'unité complète sans qu'une douille spéciale soit nécessaire dans l'instrument pour la fixation de la lampe

  
à luminescence. La lampe à luminescence peut être maintenue dans l'instrument uniquement à l'aide des éléments de contact opposés coopérant avec les éléments de contact du socle. Grâce à la forme suivant l'invention de la lampe à luminescence on peut également réduire la hauteur axiale de la lampe. Les éléments de contact du socle sont de préférence constitués par un des fils conducteurs d'amenée d'électrode et par un des deux conducteurs aboutissant à la résistance auxiliaire, l'autre conducteur d'électrode étant

  
 <EMI ID=1.1> 

  
rect comme éléments de contact d'un des conducteurs d'électrode et d'un des conducteurs de la résistance auxiliaire on diminue le nombre de pièces du socle et on simplifie la forme de ces pièces.

  
Une jonction est également suffisante dans ce cas, à savoir la jonction entre le conducteur d'électrode et le conducteur de la résistance auxiliaire. 

  
Une autre simplification substantielle pour la fabrication de la lampe à luminescence est suivant l'invention obtenue par le fait que la résistance auxiliaire est en forme d'anneau. Grâce à l'emploi de la forme annulaire, il y a moyen de disposer la résistance auxiliaire sur le bulbe de verre ou à proximité de celui-ci, de manière telle qu'elle peut être logée dans la lampe à luminescence avec un encombrement particulièrement réduit. De cette manière on peut obtenir une diminution considérable des dimensions axiales de la lampe à luminescence. La résistance auxiliaire est disposée de préférence sous forme d'élément annulaire autour de la base écrasée de la lampe à luminescence. Mais elle peut également être appliquée par projection sur l'extérieur du bulbe en verre, de manière appropriée.

  
La pièce isolante en forme d'enveloppe dans laquelle est monté le bulbe en verre est de préférence munie d'un fond pour la formation d'une cuve. Cette construction permet de réaliser un bon isolement des éléments de contact du socle de la face arrière de la lampe à luminescence. La lampe à luminescence peut être montée dans des instruments électriques en plaçant le fond de la pièce isolante en forme de cuve sur une base, sans que cette base constitue un isolant sûr. De cette manière, est facilité non seulement le montage de la lampe à luminescence dans l'instrument, mais encore est diminuée la hauteur nécessaire pour le montage dans l'instrument.

  
D'autres détails avantageux résultent de la description de l'exemple de réalisation.

  
Le dessin représente trois formes de réalisation de l'invention.

Le deuxième conducteur d'électrode 5 est relié au deuxième conducteur 9 de la résistance auxiliaire 7 au point 11. Dans cette forme de réalisation la lampe à luminescence ne comporte qu'un seul point de-jonction à fabriquer, à savoir le point de jonction entre le conducteur d'électrode. 5 et le conducteur 9 de la résistance auxiliaire 7.

   Dans la lampe à luminescence suivant l'invention des éléments de contact de socle supplémentaires ne sont pas nécessaires étant donné que les éléments de contact du socle sont constitués par un des conducteurs d'électrode 4 et par un des conducteurs 8



  LUMINESCENCE LAMP.

  
The known small-sized luminescence lamps have on their glass bulb containing the electrodes, a base, which carries as contact elements an annular lateral contact element and on their front surface a base contact element. The annular side contact element and the base contact element are kept apart by a filler mass. This type of construction increases the axial length of the luminescent lamp. In known luminescence lamps, additional junctions are also required for the electrode wires and the contact elements of the base.

  
The invention relates to a luminescent lamp, which is characterized by particularly simple manufacture and assembly. According to the invention, the glass bulb containing the electrodes is mounted in an insulating body in the form of an envelope. Base contact elements are provided on the casing of the insulating body consisting of electrode wires or wires for supplying the auxiliary resistors. Thanks to this construction the luminescence lamp can be mounted in electric instruments in a simple way as a complete unit without a special socket being necessary in the instrument for fixing the lamp.

  
luminescent. The luminescence lamp can be held in the instrument only by means of the opposing contact elements cooperating with the contact elements of the base. Thanks to the shape according to the invention of the luminescence lamp, it is also possible to reduce the axial height of the lamp. The contact elements of the base are preferably formed by one of the conductor wires for supplying the electrode and by one of the two conductors leading to the auxiliary resistor, the other electrode conductor being

  
 <EMI ID = 1.1>

  
rect as contact elements of one of the electrode conductors and of one of the conductors of the auxiliary resistor, the number of parts of the base is reduced and the shape of these parts is simplified.

  
A junction is also sufficient in this case, namely the junction between the electrode conductor and the conductor of the auxiliary resistor.

  
Another substantial simplification for the manufacture of the luminescence lamp is according to the invention obtained by the fact that the auxiliary resistor is in the form of a ring. Thanks to the use of the annular shape, there is a means of arranging the auxiliary resistance on the glass bulb or near the latter, in such a way that it can be housed in the luminescence lamp with a particularly compact size. reduced. In this way, a considerable reduction in the axial dimensions of the luminescence lamp can be obtained. The auxiliary resistor is preferably arranged in the form of a ring element around the crushed base of the luminescent lamp. But it can also be applied by projection on the outside of the glass bulb, as appropriate.

  
The insulating piece in the form of an envelope in which the glass bulb is mounted is preferably provided with a bottom for forming a tank. This construction makes it possible to achieve good isolation of the contact elements of the base from the rear face of the luminescence lamp. The luminescent lamp can be mounted in electrical instruments by placing the bottom of the tub-shaped insulating piece on a base, without this base constituting a secure insulator. In this way, not only is the mounting of the luminescence lamp in the instrument easier, but also the height required for mounting in the instrument is reduced.

  
Other advantageous details emerge from the description of the exemplary embodiment.

  
The drawing shows three embodiments of the invention.

in the form of an envelope, for example of synthetic material. On the side of the glass bulb from which emerge the supply conductors of electrodes 4 and

  
The interior of the envelope-shaped insulating body 6 is preferably conical in shape. The glass bulb I has a corresponding shape. In this way the bulb is firmly embedded in the insulating body in the envelope. The seat of the glass bulb in the insulating body in the envelope can be provided by appropriate means, in particular by gluing, cementing. In the conical part of the insulating body is housed the auxiliary resistance

conductor 4 emerges from the interior of the insulating body 6 and is disposed along the exterior of the insulating body in the form of an envelope. According to the invention

read directly as the lower part of the plinth. The conductor $ also emerges from the inside of the insulating body 6 and is disposed along the outside of this part. The electrode conductors 4 and the conductor 8 are held by clamping between the glass bulb I and the insulating body 6. The second electrode conductor 5 is connected to the second conductor 9 of the auxiliary resistor 7 at point 11. In this embodiment, the luminescence lamp has only one junction point to be manufactured, namely the junction point between the electrode conductor. 5 and conductor 9 of auxiliary resistor 7.

   In the luminescence lamp according to the invention additional socket contact elements are not necessary since the contact elements of the socket are formed by one of the electrode conductors 4 and by one of the conductors 8

of the auxiliary resistance. In this way the manufacture of the luminescence lamp is considerably simplified.

The embodiment shown in FIG. 2 is substantially of the same construction as the embodiment shown by

fig. I. The glass bulb I is in a shell-shaped insulating body 6, and at the lower part of the shell-shaped insulating body one of the electrode conductors 4 and one of the conductors 8 of the auxiliary resistor 7 serve. contact elements of the base. In the form of reali- <EMI ID = 6.1>

ring shape. As a result of this shape it can be housed with the smallest possible bulk near the glass bulb. In the form

In the embodiment, the auxiliary resistor is constituted by an annular element placed around the crushed base 10 of the glass bulb. By using an annular ring resistor the axial height of the luminescence lamp is reduced to a particularly great extent.

In the embodiment of figs. 3 to 5 the insulating body

6 in the form of an envelope is preferably provided with a bottom 12 for forming a tank. The contact elements of the base of the luminescence lamp are arranged on the surface of the insulating body 6. Admission to the contact elements of the base takes place by means of slots 13 in the casing of the insulating body which are preferably diametrically opposed. .

In this embodiment, the end of one of the electrode conductors 4 constitutes the contact element of the base.

The other contact element of the base is formed directly by one of the ends 8 of the auxiliary resistor 7 which is applied in the form of a ring on the glass bulb by projection or in another way. The other end 9 of the auxiliary resistor 7 is connected to the electrode conductor 5. The slots 13 through which the admission to the contact elements of the base takes place are preferably narrow. If the slits are given this shape, the opposing contact elements which cooperate with the contact elements of the base must be in the form of a knife. The slots preferably start from the bottom of the tank. In this way, the introduction of the opposing contact elements into the slots and their bringing together of the contact elements of the base is facilitated.

In order to bring the contact elements of the base into contact with the opposing contact elements, it suffices to pass the luminescence lamp with its insulating body in the axial direction between the opposing contact elements. By the fact that opposing knife-shaped contact elements cooperate with the contact elements of the base, a secure fixation of the fluorescence lamp in the electric instrument is also obtained.

contact elements of the base are sufficiently distant from the bottom 12 of the tank. This provides safe isolation of the rear face of the tank. In this way, it is not necessary to take into account, when placing the luminescence lamp in the instrument, whether the base on which the bottom of the luminescence lamp is mounted is or is not sufficiently insulated.

The luminescence lamp according to the invention is characterized by a particularly simple manufacture and assembly. As it has a low height, it can be accommodated advantageously in installation instruments, which already have small dimensions. The establishment of

the luminescence lamp according to the invention consequently does not increase the size of these instruments.
