  • Patent number: 8338923
    Abstract: A package structure of multi-layer array type LED device is disclosed, wherein a peripheral area of a substrate and a surface of lead frame are respectively installed with a convex/concave surface structure. The convex/concave surface structure increases the surface roughness of the peripheral area of the substrate and the surface of the lead frame, so a liquid package material can be filled in cavities and concave parts; thus a package member formed through the package material being solidified can be firmly combined with the substrate and the lead frame as one piece. In addition, the bottom of a lens is provided with a binder for increasing the sealing level of the lens. Moreover, the present invention adopted a soldering paste added with material having good heat conductivity, so heat generated by LED dices can be rapidly dissipated to the exterior.
