The invention discloses a structure of a white-light LED COB with CSP chip and a flip blue-light chip encapsulation and a preparation method thereof, so that problems of high difficulty of complexity of the color-tuning COB process can be solved and simple and efficient production of the customized color-tunable COB can be realized. The structure is formed by flip blue-light LED chips, low-color-temperature CSP light sources, and high-color-temperature phosphor silica gel; a plurality of strings of flip blue-light LED chips connected in parallel and a plurality of strings of low-color-temperature CSP light sources connected in parallel are connected to a positive electrode and a negative electrode jointly to form a dual-circuit structure; or a plurality of strings of flip blue-light LED chips connected in parallel and a plurality of strings of low-color-temperature CSP light sources connected in parallel are connected in parallel and then the parallel unit is connected to a positive electrode and a negative electrode jointly to form a single-circuit structure. The two kinds of circuit structures welded respectively are distributed on a COB substrate uniformly and are connected with corresponding electrodes respectively by lines on the COB substrate. A dam formed by a white dam adhesive is arranged around the two kinds of circuit structures and the blank area inside the dam is filled with the high-color-temperature phosphor silica gel, thereby forming a white-light LED COB structure.
