Abstract
A light-emitting diode (LED) streetlight structure, which includes a light-emitting module, a power module, and a lamppost. The light-emitting module is disposed on side of the power module; the lamppost is disposed on the other side of the power module and corresponds to the light-emitting module. A heat-dissipating structure is disposed on the surface of a housing of the power module. The heat-dissipating structure corresponds to a power supply in the power module, and can dissipate the heat generated by the power supply and reduce the temperature thereof. Accordingly, heat dissipation of the power supply is enhanced, and hence increasing its lifetime.
