In fact, the cause of LED fluorescent tube failure is also diversified, some are unreasonable operation, and some are caused by large fluctuations in power supply voltage and current. These problems appear more or less, depending on how we find faults and how to find faults. The reason is then solved in the most practical and simple way. For the possible problems of LED fluorescent tube products, let's share and cope with strategy sharing:
1. After the led fluorescent tube is energized, the starter beats normally, and the two ends of the tube emit light like ordinary incandescent light, while the filament is not flickering, the middle is not bright, and the tube cannot be started. Any such phenomenon indicates The LED fluorescent tube has leaked. For any LED fluorescent tube with serious air leakage, a slight trace of white smoke may appear on the inner wall of the filament at both ends.
2. When replacing the LED fluorescent tube, if the new tube is energized at both ends and the sound is extinguished with the sound, the inductive ballast is generally damaged. At this time, the filaments at both ends of the lamp tube are detected, and at least one end has been blown. In this case, the ballast should be replaced first, and then the new LED fluorescent tube is installed.
3. The starter is damaged. After the power is turned on, the two ends of the lamp are illuminated and the LED fluorescent tube can not be lit at all times. It is OK to replace the starter.
4. The two ends of the LED fluorescent tube are black, indicating that the lamp life will be finished, and the luminous efficiency is also reduced, and should be replaced in time.
5. The starter is frequently started, and the LED fluorescent tube is lit when it is not lit. Generally, the quality of the LED fluorescent tube is not good, and the qualified LED fluorescent tube with better quality should be replaced.
6. The flashing phenomenon of LED fluorescent tube is serious or there is a phenomenon that the light column is fluctuating, which proves that it can not be in the normal lighting state. The LED fluorescent lamp can be turned off and restarted. Repeated several times the failure phenomenon cannot be eliminated, indicating that the LED fluorescent tube is of poor quality. There are many impurity gases in the tube, and the new LED fluorescent tube should be replaced.
