| 摘要 |
The present invention relates to an LED lighting apparatus including a housing block having an inner heat radiation space and a power supply arrangement space, a plurality of housing heat radiation fins being provided at an inner circumference of the inner heat radiation space while being radially spaced apart from each other and protruding inwardly, the space between the housing heat radiation fins being open outwardly; an inner heat radiation block coupled with an inner part of the inner heat radiation space, a plurality of inner heat radiation fins being provided at an outer circumference of the inner heat radiation block and alternately interposed between the housing heat radiation fins with an air flowing space while radially protruding outwardly; a plate-shape cooling unit installed at an inner side of the inner heat radiation block to allow the air to flow out through the air flowing space; an LED unit coupled with an outside of the inner heat radiation space of the housing block; and a power supply unit provided in the power supply arrangement space to supply power to the plate-shape cooling unit and the LED unit. Accordingly, provided is the LED lighting apparatus in which the volume of the apparatus is minimized while the cooling efficiency can be maximized. In addition, provided is an LED lighting apparatus capable of adjusting heat radiation. |
