<p>PURPOSE:To have continuous line lighting with no darknesses by fixing a base to each end of a fluorescent discharge tube, wherein the base encloses only the upper half of the periphery and arranging continuously rod-shaped fluorescent lamps, from these bases in the longitudinal direction as protruding each base pin outside in the perpendicular direction to the longitudinal direction of the discharge tube. CONSTITUTION:A socket 13 is arranged above each base 11 of fluorescent lamps 8 continued in the 1 longitudinal direction, that allows the base 11 of the adjoining fluorescent lamp 8 to approach very much. The base 11 encloses only the upper half of the periphery at the end of each discharge tube 10, leaving the lower half exposed to permit it to emit light, so that darkness due to seam of lamps 8 can be eliminated. Each conductor 17 protruding at a stem 15 is folded down, and a filament 16 is arranged so as to approach the end of the discharge tube 10 as much as possible, so that even the ends of discharge tube can be lighted with the same brightness.</p> |
