The novel beneficial effect of this use comprises:

1, described flexible LED rope light comprises flexible PCB and plurality of LEDs; Described flexible PCB belongs to non-aggressive flexible circuit board, its structure is: comprise dielectric film and fit in many juxtaposed flat conductors on dielectric film, need on part flat conductor, be provided with and disconnect district according to circuit, LED is welded in and disconnects district, flat conductor can need to do flexibly wide or do thick according to heat radiation, make LED lamp band itself just possess good radiating effect, without radiating element is set in addition, on the other hand, the LED light source of this structure is with respect to the LED light source of aluminium base, and its cost can reduce about half; This structural flexibility LED lamp band can be realized automated production, and its cost is the half of traditional corrosivity flexible circuit board LED lamp band cost.

2, described LED light source comprises many flexible LED rope lights, and described many flexible LED rope lights are arranged to multiple zone circles, between each zone circle, equidistantly arranges; Described LED light source comprises many flexible LED rope lights, and many flexible LED rope lights equidistantly arrange side by side, and the light that these two kinds of modes can make LED panel light send is more even.

3, described LED light source is arranged at the side of LGP, can make lamp body make to obtain book more.

4, described rear interior surface is provided with reflecting coating or reflective membrane, as much as possible the casting out of light that LED light source is sent, thus improve light efficiency.

It is pointed out that enforcement arbitrary product of the present utility model not need to reach above simultaneously and produce effect.
