LED STREET LAMP HAVING HEAT DISSIPATION STRUCTURE

摘要

PURPOSE: An LED street light is provided to prevent the lifetime of an LED lamp by discharging heat from the LED lamp to the outside through a heat radiation path and a lamp post unit. CONSTITUTION: An LED street light(100) comprises a lighting unit(10), a heat radiation path(20), and a lamp post unit(30). The lighting unit includes an LED lamp. The heat radiation path supports the lighting unit and discharges heat from the LED lamp. A first heat radiation fin is formed on the outer surface of the heat radiation path between the lighting unit and the lamp post unit. The lamp post unit supports the heat radiation path.
