The present invention relates to a smart street light equipped with a fine dust purification function. More specifically, the present invention relates to a smart street light equipped with a fine dust purification function, wherein fine dust can be reduced by providing a night vision securing function as well as air purification and air sterilization functions by extending a use of conventional streetlights that are used only at night, and environmental pollution can be reduced and electric power consumption can be reduced by using electricity generated by photovoltaic power generation as electric power for driving the air purification and sterilization functions. Specifically, the smart street light equipped with a fine dust purification function according to the present invention comprises: an air purification unit provided inside a street lamp and driven by electricity supplied through a photovoltaic power generation unit to purify air flowing into the street lamp and including a fine dust filter for filtering air introduced from the outside and an ultraviolet (UV) sterilizer for an ultraviolet sterilization treatment; an air flow control unit driven by the electricity supplied through the photovoltaic power generation unit and provided on a lower end of the street lamp to allow outside air to flow into the street lamp and circulate the air purified by the air purification unit to the top to discharge the air to the outside; a lighting unit turning on by the electricity supplied through the photovoltaic power generation unit; and a photovoltaic power generation unit charging a battery by generating electric energy from a solar panel installed on an upper side of the street light and supplying a power source for an operation of the lighting unit, the air purification unit, and the air flow control unit using electric power charged in the battery, thereby providing the smart street light equipped with a fine dust purification function. 본 발명은 미세먼지정화기능이 구비된 스마트가로등에 관한 것이다. 보다 상세하게는, 야간에만 활용되던 기존의 가로등의 용도를 확장하여 야간시야확보기능과 더불어 공기정화 및 공기살균기능을 제공함으로써 미세먼지를 저감할 수 있도록 하고, 공기정화 및 살균기능의 구동을 위한 전력으로 태양광 발전에 의해 생성된 전기를 활용함으로써 환경오염을 저감하고 전력소비를 절감할 수 있도록 하는 미세먼지정화기능이 구비된 스마트가로등에 관한 것이다. 이를 위해 본 발명은 가로등 내부에 구비되고, 태양광발전부를 통해 공급된 전기에 의해 구동되어 가로등 내부로 유입되는 공기를 정화하고, 외부로부터 유입된 공기를 필터링하기 위한 미세먼지필터와 자외선 살균처리를 위한 UV 살균기를 포함하여 구성되는 공기정화부; 태양광발전부를 통해 공급된 전기에 의해 구동되고, 가로등 하단부에 구비되어 외부 공기를 가로등 내부로 유입시킨 후 공기정화부에 의해 정화된 공기를 상층부로 순환시켜 공기를 외부로 유출시키는 공기흐름제어부; 태양광발전부를 통해 공급된 전기에 의해 점등되는 조명부; 가로등의 상부에 설치된 태양판넬로부터 전기에너지를 생성하여 배터리에 충전하고, 상기 배터리에 충전된 전력을 이용하여 조명부, 공기정화부, 및 공기흐름제어부의 작동을 위한 전원을 공급하는 태양광발전부를 포함하는 미세먼지정화기능이 구비된 스마트가로등을 제공한다.
