Application of LED PCBs in Traffic Signal Lights
With the intelligent and energy-efficient development of urban traffic systems, LED PCB traffic signal lights have gradually replaced traditional incandescent or halogen signal lights, becoming an important part of urban traffic management. In LED traffic signal lights, the PCB serves as the core support platform, playing key roles in circuit connection, heat dissipation, and structural support. In particular, the use of high-performance LED PCBs provides strong assurance for the stable operation and long lifespan of traffic signal lights . 1. Functional and Structural Advantages of LED PCBs LED traffic signal lights are mainly composed of LED light sources, driver circuits, PCBs, and housings. Among these components, the PCB serves as the core support platform that connects the driver circuit and the LED light source. Compared with traditional wiring methods, LED PCBs offer significant advantages such as high integration, excellent thermal...
