PCT No. PCT/JP93/00913 Sec. 371 Date Dec. 20, 1994 Sec. 102(e) Date Dec. 20, 1994 PCT Filed Jul. 2, 1993 PCT Pub. No. WO94/01848 PCT Pub. Date Jan. 20, 1994A device for preventing a false lighting phenomenon is provided between a light source of the main body of a signal lamp and e cover lens for preventing the signal lamp from presenting a false lighting phenomenon. The device for preventing a false lighting phenomenon comprises a pair of complex spherical lenses formed by many numbers of spheres arranged in a matrix on planes, and configured in a chain form in which the contact points, front, rear, left and right sides, of each of the spheres truncate the spheres forming a gapless interface while the upper and lower spherical surfaces are left intact to function as spherical lenses. A shielding element is interposed between the pair of complex spherical lenses and has light transmitting slits for receiving each lens surface of the spherical lenses from corresponding sides to function as a spacer for positioning the focuses of the spherical lenses on one side in the vicinity of the vertices of the corresponding lens surfaces of spherical lenses on the other side.
