Abstract

The present invention provides a light core structure and a manufacturing process thereof Firstly, an insulation material that is temperature resistant and has high thermal conductivity is provided to serve as a base material and the base material is used to form a thermal conductive body that has a cylindrical shape, a circular tubular shape, a spherical pillar shape, or a conical pillar shape. Printing techniques are then applied to print solderable conductive metal wiring on a surface of the thermal conductive body and heat is applied to cure the wiring to form a curved surface circuit. Afterwards, SMD bonding technique is applied, together with a fixture, to mount SMD LED elements to the curved surface of the thermal conductive body through soldering. The thermal conductive body is then coupled to an adaptor element through threading or other suitable machining or being used in combination with other thermally conductive bar.
