Lamp to be introduced into an object, in particular for its decontamination

A lamp to be introduced into an object, in particular for decontaminating said object, comprising:

• a tube which extends in a rectilinear direction, having first and second tube ends, capable of diffusing a light flux;
• two electrodes fixed inside the tube, each of the two said electrodes being fixed to one end from among the two said first and second tube ends;
• an electrical device for supplying electrodes, voltage delivery means between the two said electrodes;
• the two electrodes have different lengths, one of the two electrodes having a short length and being fixed to said first tube end and the other of the electrodes having a long length and being fixed to said second tube end;
• said long-length electrode extending over a tube length and having an electrode end located at a distance from said second tube end;
• at least one radial support element being fitted around said tube length in which said long-length electrode, said at least one radial support element having at least two peripheral points of contact on said tube, said at least two peripheral points of contact being spaced apart from one another by a distance equal to at least twice the diameter of said tube;
• in that said at least one radial support element includes at least two peripheral seals and a radial support outer sleeve, said two peripheral seals being positioned between said tube and the sleeve, said sleeve also making it possible to grip said lamp, said at least two peripheral seals corresponding to said at least two peripheral points of contact and being capable of being compressed between said tube and said sleeve, and in that said sleeve is fitted around said tube and extends:
• from the end of said long-length electrode;
• at least over said length of tube, enclosing said second tube end including said long-length electrode.
