Single-ended and double-ended energized LED fluorescent tube
Due to actual wiring needs, led fluorescent lamps are usually double-ended energized, and there are also single-ended energization. The main thing is to change the wiring method of the input end wire.
For double-ended plugs, the two pins are short-circuited internally. When wiring, you only need to connect any pin to achieve the purpose of electrification.
For single-ended plugs, the two pins of the plug are independent, and the two pins are not connected together. There are two types of pins on the other end of the plug. One is two completely independent needles. One is internally connected, and is mainly used to replace single-ended inductive ballast fluorescent tubes. According to the principle of auxiliary circuit. At this time, the led tube needs to be turned on. After the starter is removed, an led starter is also needed, which is this kind of single-ended energized led tube.
Of course. You can also remove all the auxiliary circuits and directly energize the single-ended circuit. That's simple. It's okay in China. However, in European and American countries, their labor is too expensive. If you hire an electrician for energy-saving transformation, the labor is quite expensive and not cost-effective. Therefore, this simple transformation is more cost-effective. In fact, in the long run, energy-saving retrofits are more cost-effective
Besides, it is really troublesome. Our Langte also has a compatible led tube. No need to change anything. Replace the led tube directly. It is only necessary to ensure that the ordinary fluorescent lamp must be working properly before replacement. Otherwise, if there is a short circuit, the compatible LED tube will be burned out.
