Abstract
The invention provides a light-emitting diode (LED) street lamp automatic control system and an LED street lamp automatic control method. The LED street lamp automatic control system comprises a control processing unit, a sensitizing unit, a light intensity analyzing unit and an LED lighting unit. The LED lighting unit is arranged under a lampshade of an LED street lamp, and the sensitizing unit is arranged above the lampshade of the LED street lamp. Accordingly, light sent out by the LED lighting unit is not sensed by the sensitizing unit.
