A further object of the present invention to provide a system starter without removing the conventional fluorescent lamps as facelift when configured LED lamp to a conventional fluorescent lamp having a dual LED circuit.

The present invention is to solve the problems of the prior art techniques employed, there is a system comprising a first rectifying circuit in the LED lamp, wherein the AC input end connected to the first terminal point of the lamp, and the other end is connected a second termination point of the lamp. Second rectifier circuit, the AC input terminal, wherein a first end connected to the termination point of the lamp, and the other end connected to a second termination point of the lamp tube. The dual LED circuit lamp ballast after binding, a combination of LED lamps starter set.

Compared to existing products, the present invention provides a dual LED circuit lamp products, regardless of when the LED lamp plugged into the newly designed lighting group, or use the LED lamps in the old groups, able lit successfully used, is not limited by the lamp group. Whether old fluorescent lamps (e.g., prior T5日光灯具) or new set of LED lamps designed, may be suitable LED lamp of the present invention.

Furthermore, through the double-loop LED lamp design of the present invention, so that the user will install the LED lamp to a conventional fluorescent lamps, the traditional fluorescent lamps without completely configured in the original starter removed, but may be omitted and facelift, trouble in use.

Used in particular embodiments of the present invention, by the following examples and the accompanying drawings described further. BRIEF DESCRIPTION
