Abstract
The present invention relates to a method for preparing a carbon nanotube-based heat-dissipating material and an LED lighting device. The LED lighting device comprises second LED substrates and a heat-dissipating frame. The heat-dissipating frame comprises: a frame body formed in a polygonal column shape being open at its upper and lower ends, in which substrate contact surfaces, with which the second LED substrates respectively come into contact, are formed on outer sides of the frame body; and auxiliary heat sinks made of a carbon nanotube-based heat-dissipating material and attachably and detachably provided on inner sides corresponding to the substrate contact surfaces of the frame body.
