1. A manufacturing method for an axially symmetric light-emitting diode assembly, the method comprising steps of:

  • providing a substrate, which has an central axis; and

    forming a plurality of light-emitting areas on the substrate, wherein the light-emitting areas are arranged with axial symmetry around the central axis and insulated from each other, each said light-emitting area having one light-emitting diode and having dimensions the same as the corresponding light-emitting diode, and a plurality of the light-emitting diodes being electrically connected to each other;

    wherein the substrate is provided with a plurality of trenches through an etching process by which the plurality of said light-emitting areas is defined and each of the trenches is capped by an insulation layer to insulate two said adjacent light-emitting areas.
