1. A light emitting diode structure comprising:

  • a silicon substrate having a cup-structure with a parabolic shape thereon and a plurality of through-holes at a bottom of the cup-structure penetrating the silicon substrate;

    a reflective layer disposed on a top surface of the silicon substrate in the cup-structure;

    a conductive layer filling up the through-holes at the bottom of the cup-structure and protruding out from the through-holes, wherein a part of the conductive layer protruding out from the through-holes is a base; and

    a light emitting diode disposed on top of the base, wherein the light emitting diode is located at a focus of the cup-structure.
