| 摘要 |
The present invention relates to an LED lighting heat sink which is capable of being manufactured from an aluminum plate by a relatively simple processing method, and efficiently performs heat radiation even when applied to and installed in a closed space. The LED lighting heat sink according to the present invention is an LED lighting heat sink (1) where an LED element mounting surface (2) and a radiation side surface (3) are formed integrally or continuously on one sheet metal by drawing. The heat sink of the present invention comprises radiation surfaces in a continuous manner, which are formed on a cylindrical body to face any three-dimensional direction. |
