Abstract

See full text

This invention relates to separately produce the complicated 3D curved structure and LED 3D curved lead frame to meet the demand of the complicated curved surface illumination of illumination device. First of all, draw illumination circuit with banded structure of multilayer lead frame on 3D illumination complicated curved surface, then spread these curved circuit into plane circuit, dismantle the banded structure of multilayer lead frame of circuit into circuit pattern of single layers, use process the prototype of circuit patterns of each layer with conductive metal charge tape, and produce the prototype of banded structure of multilayer conductive frame through repeated accumulation of multi-disc charge tapes, and install the LED chip on the installation seat to get LED flat lead frame, then flex the conductive metal into LED 3D curved lead frame with jig and paste on the luminous curved surface, and package them together with transparent material, for example, curved decorative lighting, spherical display advertising board, etc.; this method offers more flexibility for structure and aesthetic design, and fully utilizes the high heat dissipation capacity of main body of metal part.
