A description will be given below with reference to the schematic view of FIG.
That is, the discharge vessel including the dielectrics 2 and 3, the side plate 6, and the light extraction window member 1 provided in parallel with the discharge path is filled with a discharge gas that forms excimer molecules by the dielectric barrier discharge, and the AC power supply 22 is used. When a voltage is applied to the electrodes 4 and 5 by the microplasma 20a, 20b, 20c,
20d is stably generated. At the same time, creeping discharge plasma 7 is irregularly generated along the surface of the light extraction window member 1. Therefore, the light output becomes unstable. further,
For the radiance obtained from the light extraction window member 1,
In addition to the positive columns of the microplasmas 20a, 20b, 20c, and 20d, the radiated light from the surface discharge plasmas 21a, 21b, 21c, and 21d generated on the surfaces of the dielectrics 2 and 3 greatly contributes, Therefore, it was found that when the length of the light extraction window member parallel to the discharge path is shorter than the discharge path length of the dielectric barrier discharge, the luminous efficiency is extremely lowered.

As shown in FIG. 3, in a dielectric barrier discharge lamp having a light extraction window member 1 provided in parallel with the discharge path of the dielectric barrier discharge, the discharge path of the light extraction window member 1 is When the parallel length H exceeds the discharge path length L of the dielectric barrier discharge, the recess 23 is formed, and as a result, the discharge path length of the creeping discharge becomes long and the tube forming the recess 23 is formed. It is difficult to irradiate the wall with radiation from the dielectric barrier discharge lamp.
Is less likely to occur. Further, the length H parallel to the discharge path of the light extraction window member 1 is configured to exceed the discharge path length L of the dielectric barrier discharge, so that the creeping surface generated on the surfaces of the dielectrics 2 and 3 is formed. Discharge plasma 21a, 21
The emitted light from b, 21c, and 21d can be efficiently extracted, and thus high efficiency can be obtained. When the value obtained by dividing H by L is 1.2 or more, the effects of stabilizing light emission and improving efficiency are further exhibited.

When processing is performed using light, it is desirable to bring the object to be processed and the light source as close as possible from the viewpoint of light utilization efficiency. When processing the surface of a flat object to be processed, if a light source with a large light emitting surface such as a flat light emitting surface is used, the distance between the surface of the object to be processed and the light source is spread over the entire light emitting surface of the light source. It is generally difficult to keep constant, that is, it is generally difficult to keep the distance between the planes constant, so that the irradiation dose on the surface of the object to be treated becomes non-uniform and uniform. Processing is impossible.
Since the light extraction window member of the dielectric barrier discharge lamp of the present invention has a narrow band shape and can form a high-luminance band-shaped irradiation surface, when the dielectric barrier discharge lamp of the present invention is used, In this case, the distance between the plane and the band may be kept constant, and the band-shaped portion on the surface of the object to be processed can be uniformly irradiated. By using the dielectric barrier discharge lamp of the present invention and moving the flat object or the dielectric barrier discharge lamp relatively in the width direction of the window member,
The surface of the flat object can be uniformly treated. The use of the dielectric barrier discharge lamp of the present invention becomes more advantageous especially when the object to be treated is a film and it is difficult to maintain a flat surface over a large area.
