Abstract:
1. An LED comprising: an electrode layer comprising a first section and a second section electrically insulated from the first section, and a through hole defined in the electrode layer to space the first section and the second section; an electrically conductive layer formed on and electrically connected to the second section of the electrode layer, an electrically conductive pole protruding out from the electrically conductive layer; an LED die comprising an electrically insulating substrate arranged on the electrically conductive layer, and a P-N junction formed on the electrically insulating substrate, the P-N junction comprising a first electrode and a second electrode, the electrically conductive pole extending through the electrically insulating substrate to electrically connect the first electrode of the P-N junction to the second section of the electrode layer; a transparent electrically conducting layer formed on the LED die, the transparent electrically conducting layer electrically connecting the second electrode of the P-N junction to the first section of the electrode layer; an electrically insulating layer located between the LED die, the electrically conductive layer, and the transparent electrically conducting layer, wherein the electrically insulating layer is adapted to insulate the transparent electrically conducting layer from the electrically conductive layer and the second section of the electrode layer; and wherein the through hole communicates with the continuous gap and is coaxial with the continuous gap.
