Abstract
A heat radiator comprises a heat radiation base plate, a plurality of heat conduction columns and a plurality of heat radiation fins, wherein one end of each heat conduction column is fastened on the heat radiation base plate; two adjacent sides of each heat radiation fin are respectively in a fixed connection with the heat radiation base plate and one heat conduction column; and the heat radiation fins are distributed on the periphery of the heat conduction column at intervals. In the heat radiator, the heat radiation fins are distributed on the periphery of the heat conduction column at intervals, so a heat radiation area is increased; multidirectional passageways formed between the heat radiation fins enables the heat radiation fins to conduct heat exchange with air; and when heat saturates, micro eddies are formed and extra heat is taken away, so great heat radiation effect of the heat radiator is improved. Besides, an LED street lamp using the heat radiator is also provided.
