High Frequency Electrode less Induction Lamp is called electrode less lamp for short. Inside the bulb there is no filament or electrode, rather, it is consist of a current rectifier, hollow discharge bulb and a coupler. The electromagnetic field of the high frequency generator establishes links with the internal bubble by induction, causing the cumulative ionization of the gas inside the bulb and making the gas turn into plasma. While returning to the ground state, those exited atoms of the plasma will radiate ultraviolet light of 253.7nm, which invigorates the phosphor on inner wall of the bulb to give off visible light.
     High Frequency Electronic Discharge Lamp has a lifespan of more than 10 years with an average lifespan of 6-8 years. For this reason, it hasbecome the first choice of the illumination in factory, government, campus. Public squares, halls, stations, wharfs, airports, highways, tunnels, municipal roads and so on. It is especially applicable to the place which has high requirements on illumination liability, long lifespan, also, it is applicable to places where it is difficult to change the lights or it generates high costs when changing the lights.
