The utility model discloses an add an oval pad or two circular pads on the rectangle pad of conventional PCB board, wherein add two circular pads on a rectangle pad, an oval pad is added to another corresponding rectangle pad, through an oval pad of addding, two circular pads can increase with the area of contact of LED lamp pin, guarantee when the winding, LED lamp pin can be fully with the pad contact of PCB board, also can not have the phenomenon of rosin joint when the welding simultaneously.

The pin pad of LED lamp set up respectively at the both ends on long limit, its area of contact that has increased the pad, with PCB board welding process in, can guarantee that the welding is firm, the LED lamp is in and violently pastes on the PCB board, like this because the LED lamp is more endured on long limit, the bending resistance power of lamp strip is bigger.

Preferably, the two pin pads of the LED lamp are an input pad and an output pad, and are both arranged in a rectangular structure, wherein the width of the input pad is smaller than the width of the output pad.

Furthermore, the direction of the two pins of the LED lamp is perpendicular to the long side direction of the PCB.

Further, the positive main line and the negative main line are both arranged in a strip structure. Because the LED lamp is in violently pasting, on the PCB board of the same area, the positive main line of lamp strip can be walked wideer simultaneously, and the head and the tail pressure drop of lamp strip is just littleer, and head and the tail luminance is more unanimous, and the same reason lamp strip also can be done narrowly, more makes things convenient for the customer to use.

Preferably, the substrate of the PCB is made of a PI film material, and the PI film material has enough flexibility and can be wound or bent randomly to meet different requirements of customers.

The utility model has the advantages as follows: the utility model discloses a pin pad of design LED lamp is on long limit, and the corresponding pad that sets up the PCB board, through addding two circular pads, an oval pad, realizes that the LED lamp is violently pasted, and it is bigger to increase the tolerance capacity of LED lamp on long limit, and the bending resistance that makes the lamp strip is done all can bigger. Simultaneously the utility model discloses a with positive main line, burden main line all set up long structure, make the head and the tail pressure drop of lamp strip just littleer, head and the tail luminance is more unanimous.
