OPTICAL SEMICONDUCTOR LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an optical semiconductor lighting device capable of improving heat protection efficiency and dust proof efficiency.

SOLUTION: The optical semiconductor lighting device includes a housing which includes a first end part and an opened second end part opposed to the first end part, a light source module arranged inside the housing, a fan which is arranged neighboring the light source module in the housing and blows air toward the light source module by rotating in a first direction, and a reflection shade arranged neighboring the second end part of the housing. The housing possesses a plurality of lower end support members which are spaced apart from each other projecting around the lower side and connected with the reflecting shade so as to form a plurality of outside ventilation holes.
