Abstract:
1. An LED package structure, comprising: a transparent substrate having an installed surface and at least two conductive points formed on the installed surface; a first LED chip for triggering to generate first color light, wherein the first LED chip has a major light-emitting surface, a minor light-emitting surface opposite to the major light-emitting surface, at least one first electrode area with a first pole arranged on one side of the minor light-emitting surface, and a second electrode area with a second pole arranged on opposite side of the minor light-emitting surface, wherein the polarity of the first electrode area is opposite to the second electrode area, and external light is allowed to pass through the minor light-emitting surface; wherein the major light-emitting surface of the first LED chip faces the installed surface of the substrate, and the first LED chip is arranged on the installed surface of the substrate; at least one second LED chip for triggering to generate second color light, wherein the at least one second LED chip is arranged on the minor light-emitting surface of the first LED chip, and the second LED chip has a major light-emitting surface, a minor light-emitting surface opposite to the major light-emitting surface, a first electrode area with a first pole formed on one of the major and minor light-emitting surfaces, and a second electrode area with a second pole arranged on one of the major and the minor light-emitting surfaces; a conductive unit connected between the electrode areas and between the electrode area and the conductive point for parallel or serially connecting the two LED chips together; and at least two external electric conduction units for electrically connecting the two corresponding conductive points of the substrate with an external circuit.
