Lighting device using high power led with multiple lead

A lighting device, comprising:

• a first material whose center has an obconical through channel with a larger opening on a top side and a smaller opening on a bottom side of said first material, said bottom side coated with a high thermal conducting insulation paste;
• a second material having an indentation in the center on a top side of said second material, said top side coated with a high thermal conducting insulation paste around said indentation;
• at least a light generation chip positioned inside said indentation of said second material;
• a plurality of metallic leads, each having a wiring section, a zigzag section, and a soldering section;
• wherein a top side and a bottom side of said wiring sections coated with a high thermal conducting insulation paste;
• said metallic leads arranged in a radial manner around said indentation so that said soldering sections fanning out radially;
• said second material, said metallic leads, and said first material are stacked in this order from bottom to top and pressed to that said wiring sections sandwiched between said first and second materials;
• said first material, said second material, and said metallic leads are electrical insulated;
• said light generation chips are electrically connected to said wiring sections, respectively;
• and said through channel is partially filled with a packaging material.
