A light emitting diode (LED) street lamp control system includes a control module and an LED street lamp unit coupled with the control module. The control module includes a dimmer module, a driving module, and a light source module coupled with the driving module. The dimmer module is coupled with the control module and receives a signal from the control module. The dimmer module also can transmit a signal to the control module. The dimmer module is coupled to the driving module by an access module to control the driving module to control the light source module.
