Further, said lamp holder is provided with pin in the fluorescent tube contact of stretching out lamp holder, and fluorescent tube links to each other with mount pad through pin in the fluorescent tube contact.This connected mode makes mount pad and fluorescent tube be separated, and has made things convenient for the maintenance and the maintenance of LED fluorescent lamp.
Further, said fluorescent tube main body comprises that one is provided with the installed surface of heat radiation groove, and said installed surface is provided with the card rail, and said PCB aluminium base is connected on the card rail, has louvre on the said heat radiation groove.The PCB aluminium base can directly be plugged in the card rail when installing; Easy to assembly, and, a heat radiation groove is arranged between PCB aluminium base and the fluorescent tube main body; Have louvre on the heat radiation groove; Hot-air around the PCB aluminium base and the separation of the air in the fluorescent tube main body communicate in different chambers and through louvre like this, have quickened cross-ventilation like this, have improved radiating efficiency.
Further, said fluorescent tube main body comprises the radiating part with the integrated arc surfaced of said installed surface; Said radiating part is provided with some grooves; Said groove runs through the cambered surface of radiating part along the axis direction of fluorescent tube main body.The radiating part of fluorescent tube main body adopts arc surfaced, and which is provided with groove, and this mode has increased the contact area of radiating part and fluorescent tube extraneous air, has improved radiating efficiency to a certain extent.
The invention has the beneficial effects as follows: this LED fluorescent lamp heat radiation is functional, and service life is longer, and cost performance is higher, and is simultaneously simple in structure, compact, is fit to mass industrialized production.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, a kind of LED fluorescent lamp comprises mount pad 31 and fluorescent tube 41; Fluorescent tube 41 comprises fluorescent tube main body 2, diffuser 1; PCB aluminium base 7 is set on the fluorescent tube main body 2, led light source 9 is set on the PCB aluminium base 7, fluorescent tube main body 2 two ends are provided with the lamp holder 6 that is conducted with PCB aluminium base 7; Mount pad 31 links to each other with said lamp holder 6; In the said mount pad 31 the drive circuit board group 4 that links to each other with lamp holder 6 is set, mount pad 31 both sides are provided with pin 10 in the mount pad contact, and said mount pad 31 both sides are provided with and supply the open slot 11 that pin 10 stretches in the mount pad contact; Said open slot 11 is provided with the interior needle shield 12 of sealing open slot 11; Pin 10 communicates with drive circuit board group 4 in the said mount pad contact, and said mount pad 31 back sides are connected with arc lamp socket card pad 5, are provided with the gap between the said lamp socket card pad 5 and mount pad 31 back sides; Establish an air vent 8 on the said PCB aluminium base 7, said lamp holder 6 upsides are provided with venthole 61, and said lamp holder 6 downsides are provided with air admission hole 62; Said lamp holder 6 is provided with pin 63 in the fluorescent tube contact of stretching out lamp holder 6, and fluorescent tube 41 links to each other with mount pad 31 through pin 63 in the fluorescent tube contact; Said fluorescent tube main body 2 comprises that one is provided with the installed surface of heat radiation groove 21, and said installed surface is provided with card rail 23, and said PCB aluminium base 7 is connected on the card rail 23, has louvre 22 on the said heat radiation groove 21; Said fluorescent tube main body 2 comprises the radiating part 24 with the integrated arc surfaced of said installed surface; Said radiating part 24 is provided with some grooves; Said groove runs through the cambered surface of radiating part 24 along the axis direction of fluorescent tube main body 2.
