Summary of the invention
In order to overcome the deficiency that prior art exists, the purpose of this utility model is to provide a kind of maintenance, good heat dissipation, emitting led fluorescent tube of long, low-cost 360 degree of life-span be convenient to.
For reaching above purpose, the utility model provides a kind of 360 degree emitting led fluorescent tube, it comprises lamp socket, the drive circuit that is connected with described lamp socket, is arranged on three LED substrates of described lamp socket inside, three described LED substrates surround equilateral triangle, the lateral surface of described LED substrate is provided with a plurality of led chips, also be provided with the gear-like radiator of forming by a plurality of fin on the described lamp socket, have the kink of an arc on each fin of described gear-like radiator at least.
Further improvement of the utility model is, also is provided with the triangle radiator on the described lamp socket, and one side of described triangle radiator is connected with described LED substrate, and another side is connected with described gear-like radiator.
Further improvement of the utility model is that the outward flange of described triangle radiator is connected with described gear-like radiator inward flange.
Further improvement of the utility model is that described triangle radiator and gear-like radiator are one-body molded.
Further improvement of the utility model is that described LED substrate and triangle radiator binding face scribble heat-conductive coating.
Further improvement of the utility model is that described gear-like radiator is arranged on the two ends of described lamp socket.
Further improvement of the utility model is that described gear-like radiator and lamp socket are fixed by screw.
