Patent ID: 8772793

Claim:
A light emitting diode (LED) comprising: an electrode layer comprising a first section and a second section electrically insulated from the first section; an LED die arranged on and electrically connected to the second section of the electrode layer; a transparent electrically conductive layer formed on the LED die, the transparent electrically conductive layer electrically connecting the LED die to the first section of the electrode layer; an electrically insulating layer located between the LED die and the transparent electrically conductive layer to insulate the transparent electrically conductive layer from the second section of the electrode layer; and an electrically insulating base located below the electrode layer, the electrically insulating base comprising a first electrode part and a second electrode part attached thereon, the electrode layer being arranged on the base and the first and second sections of the electrode layer respectively electrically contacting the first and second electrode parts; wherein bottom surfaces of the first section and the second section are coplanar, top surfaces of the first electrode part and the second electrode part are coplanar and respectively contact the bottom surfaces of the first section and the second section; wherein a through hole is defined in the electrode layer, an electrically insulating material is filled in the through hole to divide the electrode layer into the first and second sections, the through hole is below the LED die and entirely surrounded by the first and second sections, a gap is defined between the first electrode part and the second electrode to make the first electrode and the second electrode electrically insulate from each other, the through hole is coaxial with the gap, and the through hole has a width smaller than a width of the gap of the base.
