Pin distribution structure of patch type LED lamp

The pin distribution structure comprises a support, a left pin and a right pin, the bottom face of the support is rectangular, and the longitudinal side length of the bottom face of the support is larger than the transverse side length of the bottom face of the support. A longitudinal center line, a plurality of left pins and a plurality of right pins penetrate through the center point of the bottom face of the support and are distributed on the left side and the right side of the longitudinal center line respectively, the sum of the longitudinal side lengths of the left pins is A, the sum ofthe longitudinal side lengths of the right pins is B, and the ratio of A to B is 1: 0.7-1.3. According to the utility model, the structure is simple, the ratio of the sum of the longitudinal side lengths of the left pin to the sum of the longitudinal side lengths of the right pin is limited; according to the surface mount type LED lamp, the sum of the longitudinal side lengths of the left pin andthe right pin is kept equa
