Document Type and Number:
WIPO Patent Application WO/2021/206198
Kind Code:
A1
Abstract:
The present invention has been made to solve a problem, and it is the objective of the present invention to provide LED lighting having an easy-to-assemble radiation fins directly attached to a metal PCB, wherein radiation fins are directly connected to a metal PCB on which LED elements are provided, thereby simplifying the manufacturing process and improving the heat-dissipation efficiency. In order to accomplish the above-mentioned objective, the present invention provides LEDs directly attached to a metal PCB, and a method for manufacturing same, an outdoor LED lighting comprising: a metal PCB having LED elements on one surface thereof; and radiation fins disposed around the other surface of the metal PCB and coupled to the metal PCB through fastening screws, the radiation fins having a fastening female-screw bar for forming a fastening line between same and the metal PCB, fastening protrusions formed to be fitted to the fastening line, and one surface configured to make surface contact with the other surface of the metal PCB.
