Patent abstract
A light emitting diode lamp includes a light emitting diode and a circuit board having a circuit layer and a heat conductive layer. The circuit layer includes at least one mounting area having a first electrode, a second electrode and a heat conductive section spaced from each other. A heat conductive pole is provided corresponding to the heat conductive section. Two opposite ends of the heat conductive pole are thermally attached to the light emitting diode and the heat conductive layer of the circuit board, respectively. A spacing between the heat conductive section and each of the first electrode and the second electrode ranges from 0.7 millimeter to 1.45 millimeters.
