Light-emitting diode streetlight structure

A light-emitting diode streetlight structure, comprising:

• a light-emitting module, comprising at least a light-emitting apparatus and a heat-dissipating base, said light-emitting apparatus disposed on said heat-dissipating base;
• a power module, disposed on one side of said light-emitting module, comprising a first housing, a second housing, a power supply, and a driving circuit board, said driving circuit board disposed in said first housing, said power supply disposed in said second housing, said driving circuit board connected to said power supply, said second housing disposed in said first housing, said light-emitting apparatus connected to said driving circuit board, said second housing having a heat-dissipating part on its surface, and said heat-dissipating part corresponding to said power supply and having a plurality of heat-dissipating fins;
• and
• a lamppost, disposed on one side of said power module, and corresponding to said light-emitting module;
• wherein said heat-dissipating base comprises:
• a heat-dissipating body, disposed on one side of said power module and having a plurality of heat-dissipating fins and a plurality of heat-dissipating holes, said heat-dissipating body having a sliding trench on each of both sides, respectively;
• a frame having at least a sliding block on each of both sides, respectively;
• said sliding block corresponding to said sliding trench on each of both sides of said heat-dissipating body, and said sliding block slidably disposed in said sliding trench on each of both sides of said heat-dissipating body;
• and
• a heat-dissipating cover, disposed on the other side of said heat-dissipating body, corresponding to said heat-dissipating body, and having a plurality of heat-dissipating holes.
