Claim:
1. An LED 3D curved lead frame for an illumination device, comprising: a plurality of bent strip-shaped monolithic lead frames; the plurality of bent strip-shaped monolithic lead frames comprising a plurality of installation seats, wherein each one bent strip-shaped monolithic lead frame comprises an installation seat; LED chips; a high potential electrode contact; a low potential electrode contact; a power contact; a spiral joint; a conductive through hole; a plurality of insulating joints; the plurality of installation seats being connected by a plurality of wires, the LED chips being installed on the plurality of installation seats; each of the plurality of bent strip-shaped monolithic lead frames comprising a conductive metal; the conductive metal having a thickness within a range from 0.05 mm to 2 mm; the plurality of bent strip-shaped monolithic lead frames being superimposed into a multilayer lead frame; each of the bent strip-shaped monolithic lead frames being divided into multiple sections, the multiple sections being isolated by the plurality of insulating joints; the conductive through hole filled with a conductive adhesive which enables the conductive metals of two superimposed monolithic lead frames to have the same potential; the conductive metal comprising a ferrous metal, a non-ferrous metal and a copper foil sheet with an insulating layer; the high potential electrode contact is connected to power contact on the spiral joint a wire; and the low potential electrode contact is connected to the spiral joint.
