Led city light inspection procedure
The LED street light power module must not only be designed in accordance with the above requirements, but must also undergo rigorous inspection procedures:
1. Control devices with constant voltage output function or constant current output function or both shall be tested with the safety standard GB19510.12/IEC61347-2-13.
2. For the control device that only has the function of controlling the logic change of LED brightness, darkness, flashing, color, etc., the GB19510.12/IEC61347-2-11 safety standard shall be used for inspection.
3. If a control device has both the above-mentioned functions, it shall be tested in accordance with the safety standards of GB19510.12/IEC61347-2-13.
