PURPOSE: A solder composition of an external electrode fluorescent lamp is provided to the solidus point of solder, since bismuth(Bi) and copper(Cu) are added in tin which is a fundamental component of the solder. CONSTITUTION: A solder composition of an external electrode fluorescent lamp comprises tin, bismuth, and copper. The tin is a fundamental component of solder(5) composition of a fluorescent lamp. The content of bismuth is 0.1-10.0% based on the weight of solder composition of the fluorescent lamp. The content of copper is 0.1-1.0% based on the weight of solder composition of the fluorescent lamp.
