Kaysen's lamp is based on the basic principle of electromagnetic induction and gas discharge.

    Electrodeless lamp is through the ballast output high frequency signal is transmitted to the wound on the annular magnetic core coil, the core to form a closed magnetic field, and further induced inside the tubes in a toroidal electric, through the annular induction electric field coupling forming discharge plasma based, stimulate Hg atoms 253.7nm spectral line radiation, and thus stimulate phosphor converted into visible light output.

    Because electrodeless lamp has no traditional light sources can be easily damaged in the filament and the electrode, so long life is 100 times that of incandescent lamp, 10 times of high pressure gas discharge lamp, compact type fluorescent lamp 5-10 times the life span can reach 100, 000 hours.
