ELECTRODELESS FLUORESCENT LAMP

摘要

An electrodeless fluorescent lamp is provided to rapidly spread mercury into an upper side of a bulb by storing some of mercury to an adhesive plate from an amalgam. An external sphere(11) includes an internal discharge space. An internal tube(16) is installed in the inside of the external sphere and is separated from the discharge space. A bulb(10) is formed by attaching the external sphere and a lower end of the internal tube to each other. A base(20) is coupled with a lower side of the bulb. An antenna(30) is inserted into the internal tube. An amalgam reception unit is formed at a lower end of the bulb and is connected to the discharge space in order to receive an amalgam. The amalgam is stored in the amalgam reception unit. A supporting part(110) is coupled with the inside of the amalgam reception unit. An adhesive plate(130) is attached to an upper end of a wire extended from the supporting part in order to be exposed to the discharge space.
