Abstract: The present invention provides the cooling apparatus assembly of the LED lighting device, consisting of a LED lighting apparatus mounting plate (300), heat pipes (400) that are secured at the opposite surface to the surface where the lighting apparatus is fixed, and heat radiation pins (500) that are mechanically pressed and fixed to the heat pipes. On the mounting plate (300) of said LED lighting apparatus, at least one fixing hole (320) is provided and the heat pipes (400) are fixed rearward by the binding bolt (310), perpendicular to the mounting plate. And the one end of the heat pipes (400) is comprised of a adherence pipe (441) and an inner pipe (442), where the adherence pipe(441), having circumferential uneven or rugged portion(451) at the outer surface, is positioned at the inner side of the heat pipes, and where the inner pipe (442), having a nut screw (410) to receive the binding bolt (310), is inserted into the adherence pipe (441) with pressing force.
