Light emitting diode layout structure

An light emitting diode layout structure comprising:

• a substrate having a front surface and a back surface;
• at least one light emitting chip mounted on the front surface of the substrate, wherein the at least one light emitting chip has a first pole and a second pole;
• a first conductive wire formed on the front surface of the substrate and connected with the first pole of the light emitting chip, wherein the first conductive wire extends to the back surface to form two terminals on the back surface;
• and
• at least one second conductive wire formed on the front surface of the substrate, the at least one second conductive wire having a first terminal connected with the second pole of the at least one light emitting chip, and then the at least one second conductive wire extending to the back surface of the substrate and back to the front surface to form a second terminal.
