A lamp strings wiring structure using serial and parallel connection structures. Each lamp string is formed by multiple parallel-connected lamp groups. Each lamp group comprises at least two serially-connected bulbs and comprises a positive pole end and a negative pole end externally connected, same polar ends of every two adjacent lamp groups are electrically connected, a tail-end polar end of a previous lamp group is electrically connected to a front-end polar end of the next lamp group, a tail-end polar end of the next lamp group is electrically connected to a front-end polar end of a next lamp group, and a positive pole end and a negative pole end of a first lamp group of a lamp string are electrically connected to an outputting end of a controller separately. The wiring structure has the advantages: the electricity is saved during welding, the assembly is simple and easy, and the whole attractiveness is good. |
