The present invention relates to a heat radiation device for an LED lighting apparatus which is installed on an LED lighting apparatus. The device comprises: a radiating plate which has an LED module installed on one surface thereof; a first radiating block in which a plurality of first radiating ribs slantingly installed to form an acute angle in a clockwise direction based on a longitudinal central shaft of the radiating plate on the other surface of the radiating plate, are separately arranged at a predetermined distance along the longitudinal direction; a second radiating block in which a plurality of second radiating ribs separated from the first radiating block in a width direction on the other surface of the radiating plate and slantingly installed to form an acute angle in a counterclockwise direction based on the longitudinal central shaft of the radiating plate, are separately arranged at a predetermined distance along the longitudinal direction; and a third radiating block in which a plurality of third radiating ribs separated from the second radiating block in the width direction on the other surface of the radiating plate and slantingly installed to from an acute angle in the clockwise direction based on the longitudinal direction central shaft of the radiating plate, are separately arranged at a predetermined distance along the longitudinal direction. According to the present invention, the device has radiating ribs which are slantingly installed in a crossing direction with respect to a neighboring radiating block of each of three radiating blocks, thereby maintaining a high radiating capability regardless of the direction of wind. In addition, air inputted to the radiating plate passes through the three radiating blocks, such that the number of air paths is increased, thereby maximizing a heat radiating effect. |
