Abstract

La présente invention a pour but de simplifier la fabrication en grande série des lampes à éclair à mise à feu par impulsion électrique de haute tension. Selon l'invention, les moyens de mise en ignition sont constitués par deux fils conducteurs 8, 10 scellés dans le pied 4 de la lampe 2 et faisant saillie à l'intérieur de l'enveloppe de celle-ci où ils affleurent la surface de verre 12. Leurs extrémités internes entre lesquelles le matériau d'amorçage 14 est déposé, sont dénudées. Application à la production automatisée en grande série des lampes à éclair à usage photographique.
