Abstract
The present invention relates to a light-emitting diode (LED) streetlight structure, which comprises a light-emitting module, a power module, and a lamppost. The light-emitting module is disposed on one side of the power module; the lamppost is disposed on the other side of the power module and corresponds to the light-emitting module. The light-emitting module comprises a light-emitting device and a heat-dissipating base for the light-emitting apparatus to be disposed on. The light-emitting apparatus includes a plurality of light-emitting diodes (LEDs) and a plurality of protection devices connected electrically with the plurality of LEDs. The plurality of protection devices are used for protecting the corresponding plurality of LEDs for preventing the situation when the light-emitting apparatus is failed caused by the damage of one of the plurality of LEDs.
