LIGHT DISTRIBUTION APPARATUS OF LED ROADWAY LIGHTING LUMINAIRE

摘要

PURPOSE: An apparatus for controlling light distribution of an LED lighting apparatus for a road is provided to easily perform an assembling process by coupling a lamp shade with an optical source part in a slide type. CONSTITUTION: A first lighting part(300) is located in the front of a second lighting part(400). The second lighting part distributes light in a longitudinal direction. The first lighting part is fixed by a coupling structure. The first lighting part is combined with a lamp shade fixing part formed in a first lamp shade and a second lamp shade through a lamp shade fixing bolt. A heat radiation fin fixing bolt is inserted into a heat radiation fin fixing hole combined with the heat radiation fin. An optical source part module is fixed by the heat radiation fin fixing bolt. A third lamp shade is combined with lateral sides of the first and second lamp shades.
