ELECTRODELESS FLUORESCENT LAMP

摘要

An electrodeless fluorescent lamp is provided to decrease the amount of EMI radiated from the fluorescent lamp by forming an EMI(ElectroMagnetic Interference) shielding film on the fluorescent lamp. An electrodeless fluorescent lamp includes a bulb(10), a base(20), and an antenna(31). An outer ball has a discharge space therein. An inner tube is formed inside the outer ball to form the discharge space. The outer ball is bonded with the inner tube to form the bulb. The base is coupled with a lower portion of the bulb. The antenna is inserted from the base into the inner tube and generates a magnetic field in the discharge space. A metal film for shielding a downward EMI from the antenna is formed on an inner wall of the base. A copper paste is coated on the metal film.
