Intelligent illumination system at underground garage gateway

The utility model discloses an intelligent illumination system at an underground garage gateway. The system can effectively reduce the illumination difference inside and outside the underground garage, and achieves a function of driving indication and energy conservation. The system comprises an intelligent illumination module that is used for adjusting the illumination in the underground garage, then achieves transition between the illumination inside and outside the underground garage, and eliminates garage black hole phenomenon. The intelligent illumination module comprises an illumination detection circuit used for detecting the illumination outside the garage and transmits the detection results to a DSP processor. A light modulation circuit is used for adjusting the illumination of the circuit according to a control signal given by the DSP processor. A plurality of light modulation circuits are provided. A plurality of output ports of the DSP processor are provided. Each output port of the DSP processor controls one light modulation circuit. The system further comprises a driving indication module and an energy saving control module. When a vehicle passes by the gateway of the underground garage, the driving indication module prompts another oppositely approaching vehicle to keep clear to reduce the accident rate. When the vehicle departs from the gateway, the set time delay is over, and the lamp in the underground garage automatically becomes an energy saving state.
