Preferably, described shockproof plate cover extends to the inwall of another lamp holder always from the inwall of a lamp holder of fluorescent tube; And the two ends of shockproof plate cover are fixedly connected on the inwall of lamp tube ends lamp holder.

Preferably, described shockproof plate cover is arc, and two ends connect; Draw-in groove is arranged on the inwall both sides of shockproof plate cover; The two ends of shockproof plate cover, and card wiring board within it all is fixedly connected on the inwall of lamp tube ends lamp holder.

Preferably, described louvre is separately positioned on the relative position of lamp tube ends lamp holder.

Preferably, described shockproof plate cover is PC material or plastic board material.

Preferably, described shockproof plate cover, its two ends, and card wiring board within it all is glued on the inwall of lamp tube ends lamp holder.

The beneficial effects of the utility model are:

At first, power panel and wiring board reduce the influence of power supply heat to the LED life-span not in one;

Secondly, be fixedly connected with shockproof plate cover in fluorescent tube, shockproof plate cover inwall is provided with draw-in groove, wiring board, insulation board, and circuit-board card can not cause electric faults such as short circuit or fracture owing to vibrations in draw-in groove;

Once more, the lamp holder of lamp tube ends is provided with louvre, and heat flows to extraneous in the accelerating tube;

At last, the LED light emitting diode welds in the circuit board and is not close to wiring board, thereby reduces the influence of wiring board heat to the LED life-span.

Fig. 4 is the sectional view of lamp holder shown in Figure 1.

The specific embodiment

A kind of LED fluorescent lamp as shown in Figure 1, comprises fluorescent tube 1, the lamp holder 2 of lamp tube ends and the pin 3 common fluorescent tube bodies of forming.

This LED fluorescent lamp adopts the shockproof plate cover 9 of band draw-in groove structure, and is fixed on the inwall of lamp holder 2; Draw-in groove is arranged on the inwall of shockproof plate cover 9; Shockproof plate cover 9 can adopt flexible materials such as PC material or plastic board material.

As shown in Figure 2, be welded with LED light emitting diode 5 on the wiring board 4, wiring board 4 electrically connects with the pin 3 of lamp holder 2.LED light emitting diode 5 is proper alignment in a certain order, as adopting the matrix form arrangement mode, shown in Fig. 2 or 3, can adopt LED light emitting diode 5 not to be close to the welding manner of wiring board 4 in the present embodiment, the service life of the heat effects LED light emitting diode 5 that minimizing wiring board 4 distributes.

Shown in Fig. 2 or 3, in LED fluorescent lamp described in the utility model, adopted independently power panel 6, power panel 6 can adopt metal needle to fix with wiring board 4, and electrically connect, independently power panel 6 can not be directly transferred on the lamp pearl of LED light emitting diode 5 heat of power supply; In addition, between power panel 6 and wiring board 4, be short-circuited, electric fault takes place, an insulation board 7 is set between wiring board 4 and power panel 6; Wiring board 4, insulation board 7, and power panel 6 is installed in the draw-in groove of shockproof plate cover 9 together, on the one hand, fixedly protection circuit plate 4, power panel 6, and insulation board 7 are avoided causing electric fault by vibrations institute; On the other hand, wiring board 4, insulation board 7, and power panel 6 is hidden in the shockproof plate cover enhancing visuality.

Above-mentioned shockproof plate cover 9 as shown in Figure 1, can be the inwall that always extends to another lamp holder from the inwall of a lamp holder of fluorescent tube; And the two ends of shockproof plate cover 9 are fixedly connected on the inwall of lamp holder 2 of lamp tube ends; For attractive in appearance and easy for installation, as shown in Figure 3, shockproof plate cover 9 can be designed to arc, and two ends connect; Draw-in groove is arranged on the inwall both sides of shockproof plate cover 9; As shown in Figure 2, the two ends of shockproof plate cover 9, and within it wiring board 4 of card all is fixedly connected on the inwall of lamp tube ends lamp holder, can use glue 8 directly fixedly connected herein; So, shockproof plate cover 9 has formed firm shockproof structure, and shockproof effect is better.
