Embodiment Construction
[0049] Such as Figure 5 As shown, the manufacturing method of the mesh screen of the electrodeless lighting device of the present invention is realized in the following order: the metal sheets of a certain thickness are respectively cut into quadrilaterals and circles so as to form the base material forming stage of the basic base material (S 1 ), in order to form a network structure on the above-mentioned basic base material, it is etched (etching) to form a mesh formation stage that constitutes a network structure (S 2 ), if the mesh structure has been formed, then after the cylindrical portion (21) is made, the cover portion (25) is assembled on the cylindrical portion (21), thereby forming a mesh forming stage (S 3 ), the first metal coating stage (S 4 ), the vacuum heat treatment stage (S 5 ), the second metal coating stage (S 6 ), coated with a photocatalyst substance (TiO 2 ) photocatalyst coating stage (S 7 ).
[0050] The procedures of the above-mentioned stage...
