ELECTRODELESS FLUORESCENT LAMP

摘要

An electrodeless fluorescent lamp is provided to shield EMI(ElectroMagnetic Interference) from the fluorescent lamp by forming an EMI shielding film having various structures. 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. 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. At least one ventilating tube is protruded downwards from the lower end of the bulb. A metal film for shielding a downward EMI from the antenna is formed under the bulb.
