The region of no pressure discharge is different with in the prior art power electrode directly being inserted, the utility model adopts the discharge of induction type metal electrode, the sputter effect that reduces the sputter of electrode material and fluorescent material has greatly prolonged the useful life of light fixture, and the fluorescence that simultaneously electrode is sent is bright-coloured more moving.This advantage is more outstanding when adopting the very little materials of sputter such as molybdenum, tantalum or yellow gold to manufacture when metal electrode.

Because metal electrode of the present utility model and power electrode mutually insulated, and power electrode is to insert within the wick conduit, therefore, between wick conduit and induction metal electrode, can insert the artistic type body made from dielectric substance, and the shape of artistic type body and the big or small restriction that can not be subjected to electrode, and can do some more special structures, given as embodiment.This more strengthens its decorative effect.

The utility model adopts gaseous mercury as the ultraviolet excitation fluorescent material, and this has just reduced the disadvantage that causes big mercury pollution in the prior art, has avoided because the black splotch that the mercury sputter causes.

Metal electrode and power electrode mutually insulated in the utility model, power electrode is arranged in the wick conduit of dielectric substance system.This structure has promptly been avoided contact conductor in the prior art outwards to draw from the light fixture region of no pressure and has been made the deficiency of manufacturing process complexity, can adopt the vacuum sealing to realize the sealing of wick conduit and glass shell again, overcome the deficiency that needs in the prior art with glass work lathe processing sealing.Therefore, the utility model both can be simplified production technology, can save production cost again.
