Moreover, since a single heat pipe has the limitation of the maximum rated heat transfer capacity, as the heating power consumption of the light source (heat source) is designed to be higher and higher, the number of the heat pipes needs to be increased continuously to increase the total heat transfer capacity, so the area of the heat conducting structure is increased continuously, which leads to the increase of the space and weight of the whole heat radiating structure, and when the area of the heat conducting structure is larger than the area of the light source (heat source), the heat pipe which is farther away from the light source has smaller heat transfer efficiency, which obviously causes unnecessary resource waste.
