Main purpose of the present utility model is providing a kind of fluorescent structure, by two ends one seal cover and an adapter are set respectively at fluorescent tube, be provided with and make fluorescent tube, seal cover, adapter form one, the convenient use for the space that is installed with electronic circuit in adapter inside.

A time purpose of the present utility model is providing a kind of fluorescent structure, and the outer surface system of its fluorescent tube is provided with a connecting line that can be communicated with sealed at both ends lid, and fluorescent tube gets separately when damaging and changes, to reduce the waste of resource.

The utility model is to adopt following technological means to realize:

A kind of fluorescent structure, include a fluorescent tube and an outer tube, wherein, the fluorescent lamp piping is arranged in outer tube inside, this outer tube is that transparent material is made, be provided with connecting line between outer tube inside and the fluorescent tube, the side of fluorescent tube and outer tube is provided with seal cover, and sealing is covered with can be for the pin of fluorescent tube and connecting line connection; Be provided with the adapter that an inside can hold electronic circuit in the outer end of seal cover, one end of this adapter is provided with can be for the terminal that joins with lamp socket, the other end can insert for the terminal of seal cover and form conducting, and the first end of transferring is provided with the collar that seal cover can be coated.

Aforesaid adapter, an adapter inside wherein is provided with the control circuit device that comprises rectifier and high-frequency inverter, and another adapter inside then is provided with inductor, connects with the two way circuit conducting between control circuit device and the inductor.

A kind of fluorescent structure of the utility model compared with prior art, has following remarkable advantages and beneficial effect:

Fluorescent structure of the present utility model, because integral body is combined into the non-tight formula, when the fluorescent lamp pipe has damage, can directly fluorescent tube and seal cover be changed together, keep adapter with electronic circuit, owing to do not need directly to utilize high frequency to make fluorescent light emitting tube, can improve the useful life of fluorescent tube to the filament heating.
