PURPOSE: A streetlight device with a natural air convection type heat emitting function is provided to naturally convect air through air convection holes formed in an upper case and a lower case, thereby increasing heat emitting efficiency. CONSTITUTION: A streetlight device includes an upper case(20), a lower case(30), an LED module unit, and a cover plate(50). Air convection holes(22,34) are formed on the upper case and in an edge of the lower case. The LED module unit is arranged in the lower case. The LED module unit is made of a heat emitting plate, a substrate, and a transparent cover plate. The cover plate is coupled with the upper case to cover the air convection holes. |
