As further improvement of the utility model, each described dop comprises that at least one forms the first convex sets by two strip the first projections that arrange along described pcb board width, between two described the first projections in each described first convex sets, be provided with strip groove, described claw comprises at least one strip second projection, and described the second projection is isometric and wide with described groove.

As further improvement of the utility model, each described dop comprises two the first convex sets, and each described claw comprises two the second projections, and the spacing of each described dop further groove equates with the spacing of the second projection in each claw.

As further improvement of the utility model, described LED lamp is all stretched out at the described second protruding two ends.

As further improvement of the utility model, also comprise U-shaped connecting band, described connecting band comprises the connecting band main body wide with described the first convex sets, and two external parts vertical with described connecting band main body, the described section of stretching out laterally is provided with some through holes, and the two ends of described the first convex sets length and the two ends of width are equipped with the projection that can pass described through hole.

As further improvement of the utility model, described pcb board is fixed by screws on described heat sink.

The beneficial effects of the utility model are, each LED lamp is movably connected on the dop of pcb board by claw, when one of them or several LED lamp damage, only need single taking-up to damage the LED lamp, and change, this mode, the unnecessary waste of having avoided integral replacing to bring, the use cost of having saved the LED fluorescent lamp.

The accompanying drawing explanation

Fig. 1 is the structural representation of a kind of LED fluorescent tube of the utility model;

Fig. 2 is the partial enlarged drawing of A in Fig. 1;

Fig. 3 is the upward view of LED lamp in Fig. 1;

Fig. 4 is the partial schematic diagram during mounted LED lamp not in Fig. 1.

Wherein: the 2-radiator; The 4-PCB plate; The 6-LED lamp; The 8-connecting band; The 10-projection; 12-the first projection 12; The 14-groove; 16-the second projection.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further details.

As Figure 1-Figure 4, the utility model comprises body, body comprises strip radiator 2 and removably is connected to the lampshade (not shown) on radiator 2, in lampshade (not shown), also be provided with the pcb board 4 that is connected on radiator 2, some dops are laterally arranged on pcb board 4, the LED fluorescent tube also comprises some LED lamps 6, and each LED lamp 6 bottom is provided with the claw that is connected with dop.

Each LED lamp 6 is movably connected in by claw on the dop of pcb board 4, when one of them or several LED lamp 6 damages, only needs a single taking-up damage LED lamp 6, and change, this mode, the unnecessary waste of having avoided integral replacing to bring, the use cost of having saved the LED fluorescent lamp.

As further improvement of the utility model, each dop comprises that at least one forms the first convex sets by two strip the first projections 12 that arrange along pcb board 4 widths, between two the first projections 12 in each first convex sets, be provided with strip groove 14, claw comprises that at least one strip second projection 16, the second projection 16 is isometric and wide with groove 14.

During installation, the second projection 16 of LDE lamp is snapped in to the groove 14 of second protruding 16 groups, namely complete the combination of LED lamp 6 and pcb board 4, and when the second projection 16 is skidded off to groove 14, namely complete separating of LED lamp 6 and pcb board 4, this combination is simple in structure, and is easy to operate.And second the projection 16 with groove 14 isometric and wide, under the effect of frictional force, prevent the second protruding 16 landings.

As further improvement of the utility model, each dop comprises two the first convex sets, and each claw comprises two the second projections 16, and the spacing of each dop further groove 14 equates with the spacing of the second projection 16 in each claw.

Each LED is connected with dop by two two second projections 16, connects more stable.
