Abstract:
1. A method of manufacturing a light emitting diode (LED) lamp, comprising: providing first and second light engines each including: providing a thermally conductive rod including a circular first end and a flattened second end with a distance between opposing parallel sides of the flattened second end less than a diameter of the circular first end and a face of the flattened second end perpendicular to a length of the thermally conductive rod; mounting the first and second light engines respectively over the opposing parallel sides of the flattened second end of the thermally conductive rod; forming a heatsink by an extrusion, molding, stamping, or die casting process to provide a fin structure for dissipating heat energy; inserting the diameter of the circular first end of the thermally conductive rod into an opening in the heatsink; and mounting an optical housing to the heatsink and disposed over the face of the flattened second end such that the first and second light engines are suspended within the optical housing.
