High heat dissipation LED

The invention provides a high heat dissipation LED. The high heat dissipation LED comprises a metal radiator, wherein the metal radiator is a geometric revolving body and comprises a bottom face and a backward folded side face; cooling fins are evenly distributed on the side face in the circumferential direction; a heat insulation layer is laid on the rear surface of the bottom face; an inner cavity is defined between the heat insulation layer and the side face of the radiator; a circuit board is arranged inside the inner cavity; a center through hole is formed in the center of the bottom face of the heat radiator; the circumference of the radiator is averagely divided into sub-portions of an even number with the center of the bottom face as the circle center; the sub-portions are separated by insulation media; the adjacent sub-portions are electrically connected to different electrodes of the output end of the circuit board; the adjacent sub-portions form equal-width edge joints on the bottom face; LED wafers are evenly attached to the edge joints along the edge joints; two patch pins of each LED wafer are connected to the adjacent sub-portions on the two sides of the corresponding edge joint in a cross mode. The LED has a good heat dissipation effect and low energy consumption.
