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. The sensitizing unit is used for sensing light, and transmits a sensing optical signal relevant to the sensed light to the light intensity analyzing unit according to the sensed light. The light intensity analyzing unit analyzes the intensity of the current light according to the sensing optical signal, and transmits a light intensity signal showing the intensity of the current light to the control processing unit. The control processing unit compares the light intensity signal with a first light intensity threshold, a second light intensity threshold and a third light intensity threshold, wherein the first light intensity threshold, the second light intensity threshold and the third light intensity threshold increase progressively in sequence.
