An LED package structure comprises a substrate, a first electrically conductive pattern, a second electrically conductive pattern, at least one electrically conductive element, and an LED chip. The substrate has a first surface and a second surface opposite to the first surface. The first electrically conductive pattern is disposed on the first surface. The second electrically conductive pattern is disposed on the second surface. The at least one electrically conductive element traverses the fluorescent substrate and connects the first and second electrically conductive patterns. The LED chip is disposed on the second surface and has a light extraction surface that connects the second electrically conductive pattern. The LED chip is electrically coupled to the first electrically conductive pattern via the at least one electrically conductive element.
