Problems solved by technology

Since the inner tube diameter of the general dielectric barrier discharge lamp is small (about 5-15mm) and the tube body is long (about 300-1200mm), adding a spring will increase the difficulty of installing the second electrode, and will also increase Manufacturing cost of dielectric barrier discharge lamp

[0089] Figure 5 It is a schematic cross-sectional view of the second electrode placed in the inner tube according to the second embodiment of the present invention. Please refer to Figure 5 , the second electrode 130b of this embodiment and figure 1 The second electrode 130 is similar to the second electrode 130, the difference is that the surface of the electrode portion 132b of the second electrode 130b near the inner tube 114 has a plurality of conductive protruding points 131 or conductive protruding lines 139 arranged regularly or irregularly. These conductive protruding points 131 or conductive protruding lines 139 protrude toward the inner surface 118 of the inner tube 114 and are closely attached to the inner surface 118 of the inner tube 114 . For example, the positions of some of the conductive protruding points 131 or the conductive protruding lines 139 are, for example, corresponding to the positions of the discharge wires.
