The present invention relates to an MPPT-based photovoltaic xenon street lamp illumination system device. The system achieves integration of solar energy charge-discharge control and constant currentdrive in the same main circuit, and employs a bidirectional direct current converter circuit which achieves automatic switching between photovoltaic power generation and xenon output, namely, when illumination is generated in the day, a bidirectional converter is switched to an input mode to perform storage battery storage for the solar cell generation, there is no illumination at night, the bidirectional converter is switched to an output mode, the storage battery is discharged through the direct current converter so as to provide xenon street lamp illumination electric energy. 本发明涉及种基于MPPT光伏氙气路灯照明系统装置，系统在同主电路中实现太阳能充放电控制和恒流驱动体化，采用双向直流变换器电路；双向直流变换器电路，实现光伏发电与氙气输出两者间自动切换，即在白天有光照时，双向变换器切换为输入模式，对太阳能电池发电进行蓄电池储存；夜晚或无光照时，双向变换器切换为输出模式，蓄电池通过直流变换器放电，提供氙气路灯照明电能。
