Further, described fluorescent tube integral body is that straight line is shaft-like, and its two ends have the lamp bowl, and the lamp bowl is provided with the needle-like binding post that the lamp socket with traditional line shape fluorescent lamp is complementary.

Further, the dividing plate in the shell of described lamp body and the shell is made into integration by heat conduction good metal material.

Further, its length direction of two edges of described shell is provided with the draw-in groove structure, and described lampshade is provided with hook structure, and the draw-in groove structure matches with hook structure and makes described shell and described lampshade fix.

Further, described dividing plate is provided with locating slot, and described LED luminescence unit comprises led chip and LED aluminium base, and several led chips are fixedly installed on the LED aluminium base; Described LED aluminium base is fixedly installed in the described locating slot.

Further, also be provided with heat conductive silica gel between described LED aluminium base and the described dividing plate.

Further, described lampshade is high temperature resistant, high effective transparent material.

In the utility model LED fluorescent tube fansink designs is become the part of fluorescent tube, combine together with whole fluorescent tube, overall appearance, good heat dissipation, luminance height, it is suitable for general domestic lighting, the illumination of books reading room, office lighting, hotel eatery illumination, display and demonstration illumination and warehouse storage illumination etc., is a kind of ideal green lighting source.
