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.

Abstract
A light emitting diode structure has a silicon substrate, a conductive layer, and a light emitting diode. The top surface of the silicon substrate has a cup-structure like paraboloid, and the bottom of the cup-structure has a plurality of through-holes penetrating the silicon substrate. The conductive layer fills up the through-holes and protrudes out from the through-holes. The light emitting diode is disposed on the top of the conductive layer protruding out from the through-holes and is located at the focus of the cup-structure.
