Abstract
Disclosed is an LED lighting device of which the number of LED modules thereof is changeable according to power consumption. Through a structural change of the module, heat radiation and waterproof can be greatly improved and the size, weight and manufacturing cost can be reduced. Also, a fastening bolt allows the module to be simply attached and separated and maintenance, repair and stability can be improved by providing a wiring space inside the device. Further, there is an advantage of additionally adding a light detection sensor through a cover. The LED lighting device according to the embodiment includes a plurality of heat radiating plates; at least one light source module disposed on one surface of the heat radiating plate.
