Abstract:
1. A light emitting diode package comprising: a planar substrate; a light emitting diode disposed on the substrate; a first metal layer disposed on the top surface of the substrate; a second metal layer disposed on the top surface of the substrate, the second metal layer being separated from and not contacting the first metal layer; a third metal layer disposed on a bottom surface of the substrate and functioning as an anode for the light emitting diode, the third metal layer being connected to one of the first and second metal layers; a fourth metal layer disposed on the bottom of the substrate and functioning as a cathode for the light emitting diode, the fourth metal layer being connected to the other one of the first and second metal layers; a fifth metal layer disposed on the bottom of the substrate and functioning as a thermal pad for dissipating heat from the light emitting, diode; at least two through-holes passing through the substrate, and being formed at a position that is not on a central axis of the light emitting diode and is spaced away from and outside of the light emitting diode; and a reflecting layer disposed on the first and second metal layers, the reflecting layer being coated with a reflective material, wherein a sidewall of the at least two through-holes is made of a metal material.
