摘要： An active heat dissipating LED illumination lamp includes a substrate holder, at least one LED illumination assembly, a plurality of heat pipes and a heat sink module. The LED illumination assembly is installed on a side of the substrate holder, and the heat pipes and the heat sink module are installed on the other side of the substrate holder, and a plurality of first diversion channels is formed between the heat pipes, and each heat dissipating fin has at least one ventilation hole occupying 12%˜60% of the total area to form a second diversion channel, and a second interval is defined between the bottom of the heat sink module and the substrate holder. When the heat generated by the LED illumination assembly is provided for performing heat conduction, the heat is guided actively to the second diversion channel to perform heat convection.
