LED street lights are divided into all off and some off, if all are off, you must consider whether the LED street lights have tripped. If it is tripped, you can pull the brake directly. In this case, you can check the power distribution control cabinet, open the power distribution control cabinet, and focus on the internal wiring. See if the lines are in good contact and if cables are broken.
1: The signal line is damaged. The signal from the previous board cannot be transmitted to the next board, so it is not displayed. The setting of the control card is wrong. The number of points set on the control card does not reach the actual number of points. The signals exceeding the display are not displayed.
2: The quality of the LED chip is poor. Some LED chips are of poor quality and have a short service life. It will not be long before it will be damaged, and naturally it will not appear bright.
3: The driving device is damaged. The damage of the power driving device will also cause other LED street light components to malfunction.
4: The light-emitting diode of the LED in the display screen is damaged or the cable is defective, or the power supply hardware is defective.
5: Check the LED street lamp head. Disassemble the LED street lamp head and check the internal heat sink, LED chip and power driver. The power drive controls the voltage and current. If the current and voltage are measured to be too large or too small, these will cause the LED street light to not light. At this time, you can replace with a new power supply.
6: The setting of the control card is incorrect. The number of points set on the control card does not reach the actual number of points, and the signals exceeding the display are not displayed.
