The invention solves the technical problems through the following technical scheme:
The ends of the two electrode leads in the lamp tube are respectively connected with a bunch of floating electrodes;
The floating electrode has one or more electrodes;
The floating electrode uses the same electronic powder or cold cathode electronic powder as Qi Hui;
The electrode of the long-life fluorescent lamp of the invention does not need to be shielded by a metal plate or a metal mesh, and does not need to additionally add electrode leads, and the arc bombardment of the lamp is met by using a' lightning rod' type electrode, so that harmful arc root hot spots are converted into energy beneficial to electron emission, and the service life of the fluorescent lamp electrode is greatly prolonged.
The latest scientific research achievement of our company-"long-life fluorescent lamp electrode" (also known as "double-wing electrode") was born, and the invention patent application number was 200910113957.6.
The patent of this invention, commonly known as "hanging beam lightning rod electrode", is a new T5 long-life electrode which combines lightning rod theory, arc root hot spot theory, tip discharge theory and electron cloud model to realize the coexistence of cold cathode and hot cathode. The electric shock adopts floating electrode technology, which effectively blocks the impact of mercury ions in the lamp tube on the cathode and effectively reduces the hot spot temperature, thus greatly improving the cathode life.

The electrodes produced by this patented technology can be applied to fluorescent lamps with different diameters. At present, the mass production of T5 fluorescent lamps has been realized. Practice has proved that the photoelectric parameters of T5 fluorescent lamp produced by this technology are good, the effective life is 2-3 times longer than that of ordinary fluorescent lamp, and the test life is over 20,000 hours.
