含义

LED照明驱动故障。主控检测到LED照明灯的驱动电路异常，导致照明灯不亮、闪烁或亮度异常。

常见原因

  1. LED驱动芯片损坏或过载
  2. LED灯珠烧毁（单颗或多颗开路）
  3. 驱动电路限流电阻开路或变值
  4. LED灯组与主板连接器松动
  5. 电源输出到LED驱动的电压异常
  6. LED模块进水或受潮导致短路

自助排查

  1. 断电后重新上电，看照明灯是否恢复正常
  2. 检查LED灯组插头是否松动，重新插拔确认连接可靠
  3. 观察灯珠外观是否有黑点或断裂（目测可判断是否烧毁）
  4. 用万用表检测LED驱动输出电压是否正常（通常DC 12V或24V）
  5. 若灯珠烧毁需更换LED灯板组件，驱动板损坏需更换主板

English

Meaning

LED lighting driver failure. The main control detects an abnormal condition in the LED lamp driver circuit, causing the lights to be off, flickering, or operating at abnormal brightness.

Common Causes

  1. Damaged or overloaded LED driver IC
  2. Burned-out LED beads (one or more open-circuit)
  3. Open or drifted current-limiting resistor in the driver circuit
  4. Loose connector between the LED module and the mainboard
  5. Abnormal supply voltage to the LED driver
  6. Water ingress or moisture in the LED module causing a short circuit

Self-Check Steps

  1. Power cycle the unit and check if the lights return to normal
  2. Inspect the LED module connector; reseat it to ensure a secure connection
  3. Visually inspect the LED beads for black spots or cracks — these indicate burn-out
  4. Use a multimeter to check the LED driver output voltage (typically 12V or 24V DC)
  5. Replace the LED light board if beads are burned out; replace the mainboard if the driver circuit is faulty
