The invention discloses an LED light string combination. The LED light string combination comprises at least two LED light strings, and each LED light string comprises an LED point light source with a sunshading LED lampshade and at least two LED point light source supports, wherein two adjacent LED point light source supports are sequentially connected in series and relatively rotate through a linkage hanging buckle and linkage shaft structure and are connected through a steel wire arranged in a steel wire mounting clamping buckle; the LED point light sources are connected with point light source clamping buckles in a buckled manner, and the LED point light sources are distributed on the front faces of the LED point light source supports; and LED point light sources are arranged in point light source embedding grooves in the back faces of point light source mounting blocks, and therefore the LED point light sources are distributed on the back faces of the LED point light source supports. The LED light string combination is convenient to mount and demount, mounting at a corner position is facilitated, and the LED light string combination can be made to be normalized; and the later engineering cost is reduced, the whole attractiveness of a product is improved, the maintenance cost is low, transportation is convenient, and the product incomes are effectively improved.
