Definitions
- the invention relates to a flash lamp with a gas-filled glass tube into which two electrodes protrude from the end faces.
- the invention has for its object to design a flash lamp of the type mentioned so that an exact centering of the electrodes takes place with only a small manufacturing tolerance.
- the electrodes are melted into a hollow cylindrical glass body which is inserted appropriately in the interior of the glass tube, the outer end face of each glass body being approximately flush with the corresponding end face of the glass tube and together with this end face from a layer of glass solder is covered.
- the electrodes are centered by the glass body lying inside the glass tube and fitting into it. A gas-tight closure of the flash lamp is ensured by layers of glass solder provided on the end faces, each of which is the end face of the Cover the glass tube and the glass body supporting the electrode.
- the drawing shows a flash lamp with a gas-filled glass tube 1, into which two electrodes protrude from the end faces.
- a gas-filled glass tube 1 into which two electrodes protrude from the end faces.
- only one end of the glass tube 1 is shown with the corresponding electrode 2.
- the other end is designed accordingly.
- the electrode 2 is melted into a hollow cylindrical glass body 3, which is inserted appropriately in the interior of the glass tube 1.
- the outer end face 4 of the glass body 3 lies approximately flush with the end face 5 of the glass tube 1.
- Both end faces 4, 5 are covered by a layer 6 of glass solder, as a result of which the interior of the glass tube 1 is sealed.
- the electrode 2 passes through the glass body 3 and the layer 6 and projects outwards, so that an electrical connection is possible.
- the glass body 3 enables the pin-like electrode 2 to be exactly centered, as a result of which an uneven blackening of the glass tube 1 on its inside is prevented by electrode erosion.
