When ED solar street lights are placed in the advertising space of the L light pole,

A, first of all, check whether the controller battery indicator light is lit, if not bright check whether controller and street lamp pole storage battery cables, cable is normal, the multimeter test battery voltage, battery voltage is normal, replace the controller. Second,

first, check whether controller battery indicator light. If there is no light, check the cable between controller and lamp posts battery, cable is normal. The multimeter test battery voltage. If the battery voltage is normal, replace the controller. Second, check the controller of the load indicator light is lit, the multimeter is used to inspect the output voltage, see whether there is voltage output. If there is no voltage output, replace the controller. Third, check whether the input voltage of the light emitting diode drive is normal, check whether a fuse of the light emitting diode drive in good condition, if the fuse in good condition, using a multimeter to check light emitting diode driver output voltage is normal, if is normal, please replace the light emitting diode lamp cap, if abnormal, please replace the light emitting diode driver.
