Precautions for installing LED fluorescent tubes
1. If it is a new lighting project, since the LED fluorescent tube is already equipped with a driving power supply, it can be directly connected to the 220V AC power supply, one end of the zero line L, and the other end of the live line N. The lamp will light up after power on;
2. If it is lighting renovation, there are two situations.
1. If there is an inductive rectifier in the original lamp holder, remove the starter, and the original rectifier must be short-circuited or removed; the starter must be removed, otherwise the power supply of the led fluorescent lamp will be damaged
2. If the electronic rectifier is installed in the original lamp holder, the starter and electronic rectifier must be removed, otherwise the LED fluorescent lamp will not light up. When doing lighting renovation, because the position of the fluorescent lamp is generally higher, you must pay attention to safety when working. It is recommended that two people work in a group, one person works on the top, and the other person is on the ground for protection to prevent accidents. Do not operate with electricity. There is a risk of electric shock.
3. It should be reminded that in order to save troubles and cut corners, some installers encountered the situation where an inductive rectifier was originally installed. After removing the starter, they installed the LED fluorescent lamp directly, and the led tube would also light up, as the rectifier continued. Work. At this time, the voltage across the lamp tube is as high as 300V, which will cause serious damage to the power supply of the LED fluorescent lamp. It has been working in a high-voltage state for a long time. After about 3000 hours, the lamp has severe luminous decay until it is scrapped. We hope that the majority of users will pay attention!
If you don’t understand, I hope to inquire.
