A STREET LIGHT

摘要

PURPOSE: A street light is provided to efficiently radiate the heat from a PCB of an LCD by using an air which is circulated through a post and a head unit. CONSTITUTION: A street light comprises a pillar(110) and a head unit(120) lighting around the street light. The head unit is installed at the pillar through a supporter member(130) extended from the pillar. A light source unit radiates light outside of the head unit. The pillar and the support member are a hollow shape to efficiently emit the heat inside the head unit. The inside of the head unit is communicated with the hollow shape of the pillar and the support member. A ventilation unit(111) is formed in the bottom of the pillar in order to guide the external air of the street light through the hollow to the head unit.
