Applications of Aluminum PCBs in High-Power LED Lighting
As LED lighting technology continues to advance, high-power LED lighting has been widely adopted in applications such as high-mast lighting, stadium lighting, port and terminal lighting, airport lighting, and large industrial facilities. Compared with conventional lighting equipment, high-power LED fixtures often operate continuously for extended periods, and maintenance can be costly in certain applications. These operating conditions place higher demands on the thermal management, operational stability, and long-term reliability of lighting systems. LED devices continuously generate heat during operation. If the heat cannot be transferred and dissipated effectively, the LED junction temperature can rise, affecting light output stability, luminous efficiency, and service life. PCBs not only provide electrical connections for LED devices but also serve as an important part of the heat transfer path. PCB material properties, thermal conductivity, and man...
