Abstract:
1. A LED lighting assembly, comprising: a substrate defining a body and a central hole surrounded by the body, the body defining an upper surface and a lower surface opposite to the upper surface; a thermal conductive mass positioned in the central hole of the substrate and defining an upper surface close to the upper surface of the body of the substrate and a lower surface opposite to the upper surface; a LED chip defining a bottom attached to the upper surface of the thermal conductive mass; a shell mounted on the upper surface of the body of the substrate and forming a room together with the body; a phosphor coating covering an outer surface but not including the bottom of the LED chip; a barrier surrounding and connected to a whole peripheral side of the phosphor coating for limiting the position of the phosphor coating; a first electrode electrically connected to the conductive mass and a second electrode; a first terminal electrically connected to the conductive mass and a second terminal electrically connected to the second electrode; wherein the outline of the phosphor coating is square, the barrier is a square frame; a pad is provided on the upper surface of the body to connect the second electrode to the second terminal, and the pad is disposed within the barrier and touches an inner wall of the barrier.
