Causes and solutions for non lighting of purification lamp
1. Find out the cause: check whether the LED purification lamp does not work properly due to the power supply part, which causes the bulb not to light. If so, check the power supply line, and generally the power supply is normal.
Solution: connect the LED ceiling lamp and the indicator lamp above will light up.
2. Positive and negative electrode connection: in addition to the power supply, if it does not light up, we need to check the positive and negative electrode pins of the LED purification lamp to see whether the LED purification lamp we operate is correctly connected during operation. If there is incorrect operation, the bulb will not light up.
Solution: re welding the LED purification lamp can generally solve the problem.
3. Find out why: the quality problem of the LED lamp beads themselves can also cause the LED lamp beads to not light up, because some LED lamp bead chips have leakage, which is also easy to cause the LED lamp beads to die after being used for a period of time.
Solution: try to prevent the lamp beads from being stored in a humid environment for a long time, so as to prevent the LED lamp beads from not lighting due to leakage caused by internal chip moisture.
4. Find out the cause: the short circuit of LED purification lamp may also cause the LED ceiling lamp not to light. This situation can be caused by some small companies' faulty welding in the production process of LED purification lamp, and the open circuit caused by the hot expansion and cold contraction of LED purification lamp and the extrusion of gold wire.
Solution: re welding
