The invention describes a light burner ( 1 ) comprising a discharge chamber ( 2 ) containing a gas sealed in the discharge chamber ( 2 ) by a seal ( 4, 5 ) and a pair of electrode shafts ( 6, 7 ), each of which partially intrudes from the seal ( 4, 5 ) into the discharge chamber ( 2 ) whereby a wrapping ( 8, 9 ), at least partially contained in the seal ( 4, 5 ), is freely wound around at least one of the electrode shafts ( 6, 7 ) and constrained in its motion by a number of containment elements (P<SUB>1</SUB>, P<SUB>2</SUB>, P<SUB>3</SUB>, P<SUB>4</SUB>) positioned along the longitudinal axis of the electrode shaft ( 6, 7 ).
