Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art can
To better understand the utility model and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
As shown in Figs. 1-2, a kind of electrodeless ultraviolet lamp, including fluorescent tube 1, magnet exciting coil 2, iron core 3 and mounting base 4, it is described
Fluorescent tube 1 is formed by inner tube 5 and the integrated molding of outer tube 6, it is however generally that inner tube 5 and outer tube 6 are formed by quartz glass, the fluorescent tube 1
Inert gas and mercury are filled with after vacuumizing, the ultraviolet transmittance of said inner tube 5 is lower than the ultraviolet transmittance of outer tube 6, described
Iron core 3 crosses inner tube 5 along the axis pipe of inner tube 5, and the magnet exciting coil 2 is wound on iron core 3, and the fluorescent tube 1 and iron core 3 are fixed on
In mounting base 4, the connecting line 7 of the magnet exciting coil 2 is drawn in mounting base 4.
