Variable light street lamp with brightness changing with environment

摘要: The invention relates to a variable light street lamp with brightness changing environment. is cauterized in that the comprises 220V alternating current power supply, 12V half wave commutating and voltage-stabilizing photoresistor voltage dividing circuit an illumination driving circuit. According environment, photosensitive control mode used; changed from centralized dispersed local separate control; as long environment dark or day dark, automatically lights up; according of road such rainy days, haze foggy days other natural factors, can up adjust brightness; addition, consumption reduced; service life extended; maintenance cost rate replacement significantly provides intelligent for municipal lamps.
