Abstract:
1. An excimer lamp comprising a light-emitting tube containing an excimer emission gas sealed therein, wherein a pair of electrodes extending in a direction of a tube axis of the light-emitting tube are provided inside the light-emitting tube, a cylindrical tube being made of a dielectric material and disposed inside the light-emitting tube so as to extend in the direction of the tube axis of the light-emitting tube, the cylindrical tube having an inner cylindrical surface defining an inner cylindrical hermitic space therein and an outer cylindrical surface, one of the pair of electrodes is surrounded by the inner cylindrical surface and disposed in the inner cylindrical hermetic space, the other one of the pair of electrodes is in contact with the excimer emission gas and is disposed to helically wrap around the outer cylindrical surface of the cylindrical tube and extend outwardly therefrom to the light-emitting tube, and the pair of electrodes are electrically connected to respective conductive foils hermetically embedded in end portions of the light-emitting tube.
