Abstract：Urban street lighting system is an important embodiment of the level of urban modernization. However, street lighting not only improves the urban image and urban environment, but also inevitably leads to a significant increase in call fees and huge energy consumption. At present, the widely used lighting scheme can meet the needs of night lighting, but it also causes a waste of resources. Therefore, we have designed a device that can realize on-demand lighting of street lamps to solve the problem of large energy consumption caused by the traditional street lamp scheme "constant illumination of all night lamps" in the road section where no one and no car pass through. The device combines millimeter wave radar with traditional street lamps to monitor the conditions within a certain range around the street lamps through the radar. When there is no target within the monitoring range, the street lamps go out to reduce energy consumption. When there is a target, the street lamps turn on, and adjust and control the lighting brightness of the street lamps through the control module according to the distance of the target to realize stepless dimming lighting, It can not only meet the normal lighting demand, but also save energy, improve lighting efficiency and prolong the service life of street lamps.
