The utility model relates to a remote time-difference exhaust lighting circuit which comprises an air switch, a first remote control switch, an exhaust local operation switch, a power distribution room exhaust fan, a time-delay switch relay, an indication signal lamp, a time-delay switch, a step-down coil, lighting lamp light, a lighting local operation switch and a second remote control switch. The system is small in hardware capital investment and low in cost, saves ventilation and exhaust waiting time, improves work efficiency, avoids the problems that energy is wasted due to long-term ventilation and an illumination switch is inconvenient to find at night or in an underground power distribution room, further eliminates potential safety hazards, and avoids the problems of insufficient ventilation time, remote control failure and the like due to signal delay. The operation time can be shortened, and the staff operation environment is improved.
