ELECTRODELESS FLUORESCENT LAMP HAVING FERRITE CORE

摘要

An electrodeless fluorescent lamp having the ferrite core is provided to reduce the generation of heat and increase the optical power by adjusting the angle of the ferrite core. An electrodeless fluorescent lamp comprises the pair of semicircle bodies(11,13) which are combined with each other; the magnetic field centralized portion focusing the generated magnetic field to the center of the ferrite core; the ferrite core including magnetic field centralized portion. The magnetic field centralized portion is formed into the shape getting narrow from the both sides center of the ferrite core to the top and the designated angle slope. The tilt angle of the magnetic field centralized portion is 4~6 degrees.
