These lamps have no wire conductors penetrating their envelopes, and instead excite mercury vapor using a radio-frequency oscillator.Currently, It is currently the world to promote the use of green, environmental protection, energy saving of the new light source ,In contrast with all other electrical lamps that use electrical connections through the lamp envelope to transfer power to the lamp, in electrodeless lamps the power needed to generate light is transferred from the outside of the lamp envelope by means of (electro)magnetic fields. There are two advantages of eliminating electrodes. The first is extended bulb life, because the electrodes are usually the limiting factor in bulb life. The second benefit is the ability to use light-generating substances that would react with metal electrodes in normal lamps.
No electrodes, no filament, is using the principle of electromagnetic induction, firstly, electricity generated magnetic field, then, magnetic field generated induction electricity, coupled oscillation application of the principle will produce high-frequency waves into the vacuum glass shell or glass tube, producing effect with tricolor fluorescent power, thereby, avoid the problem of electrode wastage.
