Abstract
A multiple-set heat-dissipating structure for a LED lamp for performing the heat dissipation of the LED set includes a heat-conducting base, a plurality of heat pipes and a plurality of heat-dissipating bodies. On end face of the heat-conducting base is used for adhering to and contacting with the LED set. Each heat pipe has a heat-absorbing end and a heat-releasing end, respectively. The heat-absorbing end is connected to the other end face of the heat-conducting base. Each heat-dissipating body has a hollow cylinder. The outer periphery of the cylinder is formed with a plurality of radial heat-dissipating pieces and is connected on the heat-releasing end of each heat pipe. By dispersing each heat pipe and heat-dissipating body, the heat generated by the operation of the LED set can be conducted and dissipated by each heat pipe and heat-dissipating body at multiple points. In this way, the LED set can be continuously operated under a suitable working temperature and thus its life can be elongated.
