The invention discloses an automatic searchlighting warning system for a pedestrian crosswalk. The automatic searchlighting warning system comprises an infrared life detection instrument, a lighting device and an electromagnetic wave generator. The infrared life detection instrument is used for detecting the pedestrian passing condition of the pedestrian crosswalk and controlling the lighting device and the electromagnetic wave generator to work. The lighting device comprises a photoresistor and a searchlight connected with the photoresistor in series, and the photoresistor is used for controlling the searchlight to be automatically turned on or turned off. The electromagnetic wave generator is used for sending an electromagnetic wave signal to a vehicle away from the electromagnetic wave generator by a linear distance S to warn the vehicle that some pedestrian passes through the pedestrian crosswalk. The infrared life detection instrument is electrically connected with the lighting device and the electromagnetic wave generator and then electrically connected with a power supply arranged on the pedestrian crosswalk to form a closed loop, and the lighting device is connected with the electromagnetic wave generator in parallel. The automatic searchlighting warning system avoids power waste caused by a traditional street lamp and traffic accidents caused by poor light at night, and can warn the vehicle in advance and reduce car accidents effectively.
