How to replace traditional fluorescent tubes and fluorescent tubes with LED tubes
The LED tubes appearing on the market now should be directly connected to the 220V power supply. The control power is inside the lamp. The LED tube does not need a ballast or starter.
Replacement method:
Directly remove the starter of the traditional fluorescent lamp bracket, cut off all the output and input wires of the ballast, and then pull two 200V wires into the fixed lamp holder.
Pull one to the other end to fix the lamp holder, connect it with the one that was just cut off, wrap it with insulating tape, and install the LED tube. The ballast can go or not,
Anyway, now he is no longer working and does not consume electricity.
But some people say that if the ballast is not removed, it will not affect the work, but will it consume electricity?
1. It will consume a part of the electricity, if you are not afraid of trouble, it is better to remove the ballast
2. If it is an electronic ballast, it must be replaced. Because the electronic rectifier will generate high voltage, for the led tube, the withstand voltage is less than 300v, and it is easy to be damaged.
Although Langte led lamp can withstand voltage up to 305v. For ordinary inductive ballasts, after removing the starter, it can no longer generate high voltage and is safe. Because
Under normal energization, the ballast is only equivalent to an inductor, because its structure is in the form of an inductor. Even in the case of on or off, occasionally there will be a
Back EMF, the voltage is high even if it is volts, it will not affect the quality of the LED tube. However, please note that if it is not a constant current power supply, but an ordinary linear or RC power supply,
There is no guarantee, and it will break down after a short time.
