The lighting device mainly contains a first material, a second material, at a light generation chip, and multiple metallic leads. The metallic leads are sandwiched between the first and second materials, and arranged in a radial manner around the indentation or the raised stand. The center of the first material has an obconical through channel and the center of the second material has either an indentation or a raised stand. The light generation chips are positioned in the center of the second material. High thermal conducting insulation paste is provided between the first material, the metallic leads, and the second material so that they are electrical insulated from each other. The present invention could achieve versatile color combinations and high brightness under superior heat dissipation effect, and could be applied in various types of packaging and welding.
