High frequency electrodelss lamp is a new light resource. There is not filament or electrode which ordinary bulbs hava. Instead, there is a hollow discharge glass rube and a coupler. Through inductive coupling.plasmas is produced when avalanche ionization occurs to the air in the bulb. When getting back from excited state to ground state, the atom will emit ultraviolet ray at a wavelength of 253.7nm,which will cause the fluorescence powder on the inner wall of the lamp bulb to produce visible light.High frequency electrodelss bulb has a very long service life,from 6 to 8 years in common up to 15 years. It is especially suitable for those places that require long illumination time. Or places at which light sources are difficult or expensive to replace. |
