Lighting applications include LED driver power supplies, industrial lighting, outdoor streetlights, stage lighting, and smart lighting systems. This field focuses on High Luminous Efficacy, long lifespan, and strong surge resistance. LED drivers often adopt high-frequency switching power architectures to improve conversion efficiency and stable brightness output, requiring high-speed rectifying components (SBD / SiC SBD / UFD) and high-efficiency MOSFET control transistors. Meanwhile, lighting systems must withstand instantaneous surges from lightning and power fluctuations, leading to the inclusion of protection components like TVS and Zener. BJTs and MOSFETs are also commonly used in dimming control and communication interface circuits to achieve smart lighting and energy management functions.
