Patent ID: 8581290

Claim:
An embedding type solder point-free combination structure of LED bead with substrate or lamp body, comprising: at least one embedding type LED bead, a substrate or lamp body having a structure for docking the embedding type LED bead, a fixing structure for fixing the embedding type LED bead upon insertion into a docking hole in the substrate or the lamp body; said embedding type LED bead having a heat conductive socket and at least one LED chip being packaged on a top face of said heat conductive socket, said fixing structure including a member in threaded engagement with said substrate or said lamp body to capture said embedding type LED bead in the docking hole of said substrate or said lamp body in releasable manner, wherein said LED chip of said embedding type LED bead and conductive contact points on said substrate or lamp body are maintained in electrical contact to form a solder-point free contact structure, and the heat conductive socket of said embedding type LED bead is locked in heat conductive contact with the docking hole of said substrate or said lamp body; wherein said embedding type LED bead further comprises a fastening member having a circular shape and is provided annularly about said heat conductive socket, and said fixing structure is defined between said fastening member and the docking hole of said substrate or said lamp body; and wherein said embedding type LED bead further comprises an insulation socket provided between the heat conductive socket and the fastening member, said insulation socket having a frame body and positioning portions extending outward and upward therefrom, a plurality of elastic conductive pieces being embedded in the positioning portions for electrical coupling to the LED chip, a gap being formed between the positioning portions of the insulation socket and the frame body for accommodation of said fastening member; positioning notches corresponding to said elastic conductive contacts being formed to communicate with the docking hole of said substrate or lamp body for accommodating said positioning portions of the insulation socket.
