LED street lights refer to street lights made from LED light sources, which have unique advantages such as high efficiency, safety, energy conservation, environmental protection, long service life, fast response speed, and high color rendering index. They are of great significance for energy conservation in urban lighting
The LED street light power module not only needs to be designed according to the above requirements, but also must undergo strict inspection procedures:
1. Control devices with constant voltage output function, constant current output function, or both functions should be inspected according to GB19510.12/IEC61347-2-13 safety standards.
2. For control devices that only have the function of controlling logical changes in LED brightness, flicker, color, etc., safety standards GB19510.12/IEC61347-2-11 should be used for inspection.
3. If a control device has both functions, it should be inspected in accordance with the safety standards GB19510.12/IEC61347-2-13.
Practice has proven that through scientific design and strict testing, not only can LED street light systems be protected from lightning damage, but also common mode and differential mode interference from lightning on power equipment is eliminated.
