PURPOSE: A heat dissipation structure of a street light is provided to easily perform maintenance and repair of an air filter by forming a switching unit in a pole. CONSTITUTION: A heat dissipation structure of a street light includes a pole(21), a lighting unit(24), an air blower(25), and an air filter(26). The pole is vertically installed on a ground. A hollow part is formed inside the pole. The lighting unit is supported by the pole. The lighting unit includes a light source module, a heat dissipation plate, a stabilizer, a housing, and a light transmitting cover. An air inlet and an air outlet are formed in the housing. The air inlet is connected to the hollow part of the pole. The air outlet exhausts an air flowed through the air inlet. The air blower is installed inside the pole.
