Abstract
The utility model discloses an LED street lamp radiator which comprises a conducting wall, a first cover body and a second cover body. The conducting wall comprises a first heat dissipation region, a second heat dissipation region and a third heat dissipation region which is connected between the first heat dissipation region and the second heat dissipation region.
