Excuse me, how to connect the emergency grid lamp with the LED lamp? In the past, ordinary fluorescent tubes needed ballasts, but now they are replaced by LEDs without ballasts. thank you

Now the original rectifier is directly removed, and the positive and negative poles of the original rectifier are directly connected to the two ends of the lamp holder.

Simply put, it is directly connected to both ends of the lamp without rectifier.

If the LED is split, then the positive and negative electrodes are connected to the LED power supply, and the LED driving power supply is connected to both ends of the lamp tube.

If an LED lamp is integrated, the positive and negative electrodes can be directly connected to both ends of the lamp holder.

The LED lamp here can be understood as an incandescent lamp, which only needs to supply power at both ends of the lamp.

The general design industry is 220V communication. Other low-voltage DC can also be done. Changing the power supply is simple. It is very simple to give the requirements to the manufacturer when ordering. Commonly used are 12V and 24V.
