LED tsav tsheb feem ntau suav nrog cov khoom hauv qab no:
1. Fais fab tso zis: txais voltage los ntawm lub hwj chim mov.
2. Rectification thiab Lim: Hloov AC rau DC thiab smooths voltage fluctuations.
3. Switching Element: Tswj cov kev hloov tam sim no los kho cov teeb ci LED.
4. Kev Tswj Xyuas: Saib xyuas cov LED tam sim no thiab qhov hluav taws xob kom ntseeg tau tias lawv nyob hauv qhov chaw nyab xeeb.
5. Kev tiv thaiv Circuit Court: Tiv thaiv LED thiab tsav tsheb nyob rau hauv tej yam kev mob xws li overheating, overvoltage, los yog luv luv circuits.
