Abstract (en)

[origin: EP0325157A1] It is intended to produce a gas discharge lamp, especially a flash tube, which is suitable for triggering electronic still cameras, that is to say, which is miniaturised and has a high internal resistance. The gas discharge lamp is characterised by the following features: a) the internal diameter of the glass tube (1) is less than 2 mm, b) a small plate (3), which can be tinned, is mounted externally on the electrode wires (2) which are fused into the glass tube (1), the small plate (3) having a diameter which is less than or equal to the external diameter of the glass tube (1) and carrying a soft solder layer (4), c) the thickness of the glass tube wall is less than 0.5 mm, d) the glass tube (1) consists of glass which can be subjected to high stress.
