Abstract
A LED package structure having an electro-static protective diode, the structure is disclosed. The structure comprises: an electro-static protective diode having an n-type electrode mounted on a lampstand by a conductive paste layer, so that it forms an electrical connecting with a positive leadfame. A LED having a p-type and an n-type electrode positioned on one side and a bottom on the other side of the LED mounted by an insulating layer atop the p-type electrode of the electro-static protective diode. Next a first conductive wire connects between the p-type electrode of the LED and the positive leadframe. A second conductive wire, connects the n-type electrode of the LED with the negative leadframe. A third conductive wire connects the p-type electrode of the electro-static protection diode to the negative electrode of the leadframe. Transparent resin is finally used to form a dome-shaped package.
