YUANNENGJI The LED street light is fully on or partially off. If it is fully on, you need to consider whether the LED street light has tripped. If it has tripped, just pull up the switch. In this case, you can check the power distribution control cabinet, open the power distribution control cabinet, focus on checking the internal circuit, check whether the circuit is in good contact, and whether the wiring is broken.
1: The signal line is damaged, and the signal of the previous board cannot be transmitted to the next board, so it is not displayed. The control card is set incorrectly, the control card setting points do not reach the actual points, and the signal exceeds the part that is not displayed.
2: The quality of the LED chip is poor. Some LED chips are of poor quality and have a short service life. They will be damaged in a short time and naturally will not light up.
3: The driver is damaged. The damage of the power driver will also cause other LED street light components to not work properly.
4: The LED light-emitting diode in the display is damaged or the wiring is problematic, or the power hardware is problematic.
5: Check the LED street lamp head, disassemble the LED street lamp head, check the internal radiator, LED chip, and power driver. The power driver controls the voltage and current. If the measured current and voltage are too large or too small, these will cause the LED street lamp to not light up. 此時, replace a new power driver.
6: The control card is set incorrectly, the control card setting points do not reach the actual points, and the exceeded signal is not displayed.
