But the set-up mode of two LED lamp bars 12 about so in this strip lampshade 11, having at present; Will in about the central authorities of two LED lamp bars 12 produce a space and occur; Even two LED lamp bar 12 leans on very closely; Also still can cause right ends brightness to be higher than Centromedian brightness, so can't make 1 whole of the LED fluorescent tube can be complete shinny uniformly, so can reduce the luminous efficiency of LED fluorescent tube 1.
Therefore, have manufacturer to attempt in strip lampshade 11, only placing a longer LED lamp bar 12, and this LED lamp bar 12 also drive shinny by one drive circuit 13; But drive the LED lamp bar 12 of a whole piece, will need bigger power supply, just have enough driving powers; Therefore the transformer 131 of required use also can be along with bigger power supply increased in size; And the transformer 132 of increased in size, as putting into strip lampshade 11, will be too huge because of size; And cause this drive circuit 13 can't place inside one side of strip lampshade 11; This will cause driving the LED lamp bar 12 of a whole piece, if can solve so problem, can in this LED fluorescent tube 1, drive the LED lamp bar 12 of a whole piece smoothly.
Therefore; If can the transformer of increased in size be arranged on the drive circuit board either side; Can reduce the occupied accommodation space of this drive circuit; So that in the LED fluorescent tube can by one have the electronic component of large-size drive circuit drive the LED lamp bar of a whole piece, so should be a best solution.
The utility model content
The utility model promptly is to provide a kind of and can avoids big molded dimension electronic component to occupy big accommodation space, in the LED fluorescent tube, can drive the LED lamp bar of a whole piece by one drive circuit.
Can reach the driving circuit structure that is used for the LED fluorescent tube of above-mentioned novel purpose; Wherein the LED fluorescent tube has comprised a lampshade, at least one LED lamp bar and at least one driving circuit structure; It is inner that this LED lamp bar is arranged at this lampshade; And the driving circuit structure that is connected with this LED lamp bar also is arranged at the inner either side of this lampshade; This driving circuit structure has a plurality of resistance or capacitance kind electronic component, at least one transformer and one drive circuit plate in addition, and wherein resistance or capacitance kind electronic component are inserted on this drive circuit board one side, and this transformer can be arranged on this drive circuit board one side.
In particular, have several light emitting diodes on the said LED lamp bar.
In particular, said lampshade is a strip.
In particular, said driving circuit structure is connected with this LED lamp bar, and this drive circuit board driving circuit structure is shinny in order to drive this LED lamp bar.
In particular, said transformer is then in order to provide drive circuit board and LED lamp bar shinny required power supply supply.
In particular, described big molded dimension electronic component transformer stands on this drive circuit board one side.The beneficial effect of the utility model is:
1. the utility model can avoid transformer to occupy big accommodation space, in the LED fluorescent tube, to drive the LED lamp bar of a whole piece by the one drive circuit structure, so that whole of LED fluorescent tube can be complete shinny uniformly.
