Patent ID: 7301174

Claim:
LED strip lamp comprising a light emitting diode and extruded electrodes characterized in that a shaped electrode of that LED is fixed directly to a diode connecting part on a current supplying conductor, by die bonding or other fixing means, an insulating painted layer on the current supplying conductor being locally absent, exposing a core wire, wherein the current supplying conductor comprises a metal wire rod having said insulating painted layer thereon, and further characterized in that a selected connecting part is formed on one sidewall of the current supplying conductor by removal of the insulating painted layer, and wherein a current supplying conductor is aligned and joined together with two or more current supplying conductors, and further characterized in that the distance between successive diode connecting parts is adjustable by stretching said conductor which has the form of a tube-shaped helical cable which forms a diode connecting part at the bottom of a groove formed on the exposed core wire, and another groove is formed at the periphery of the tube-shaped current supplying cable, which is wound helically.
