Abstract
PURPOSE:To prevent the occurrence of cracks and ruptures at connection sections by locally heating and softening expected connection sections with no protective films to form connection holes and connecting mating connection holes together to form a continuous discharge path. CONSTITUTION:In the method to form a fluorescent lamp with a continuous discharge path by connecting multiple bulbs 1-3, expected connection sections 13, 23, 33 are locally heated and softened with no protective film 4 and blown through to form connection holes, then mating connection holes of the multiple bulbs 1-3 are connected together to form a continuous discharge path. Since no protective film 4 exists at the expected connection sections 13, 23, 33, no metal oxide is infiltrated into the melted glass when it is heated and melted, thus no distortion is generated on the connection sections after the cooling. Ruptures and cracks can be thereby prevented.
