Fixation can be realized between pillar, no longer need to fix using adhesive tape or by gluing form, the assembly of LED light bar is simpler
List, assembly efficiency is higher, cost is lower；
(2) LED lamp tube that the present invention makes is integrally formed, and production method is simple, easy to operate；And made LED lamp tube
After forced air cooled tube is cooling, the thermal stress on glass tube can be eliminated, so that glass tube stress elimination is more thorough, glass tube is strong
Du Genggao, it is non-breakable；
(3) mold used in the present invention, can complete the LED lamp tube with pillar, fail in the prior art
A major reason for successfully producing the fluorescent tube with pillar is that the selection of mold, and mold of the present invention passes through
The formation for being set as pillar of opening provides reliable guarantee.
