LED LAMP HEAT DISSIPATING STRUCTURE

摘要

An LED lamp heat dissipating structure includes a first cover, a second cover, a heat dissipating device, and an LED light source. The first cover and the second cover cover each other to form a hollow space. The heat dissipating device is disposed inside the first cover and the second cover. The LED light source is disposed below the second cover and is in heat-conducting contact with the heat dissipating device. The heat dissipating device further includes a plurality of cover heat pipes. Each of the cover heat pipes has a heated end and a cooled end. The heated end is connected at the heat conducting base. The cooled end extends along the first flange of the first cover and the second flange of the second cover, respectively, so as to be sandwiched between the first flange and the second flange.
