I. new clothes

Connect the mains AC 220V power supply to the two lamp feet of the LED lamp tube through the switch.

II. Modification

Refitting is to transform the internal circuit of the lamps originally using ordinary fluorescent lamps according to the requirements of LED fluorescent tubes, so that they can be suitable for LED fluorescent tubes. Taking the light pipe support as an example, the modification methods are introduced as follows:

First, remove and store the general fluorescent tube on the fluorescent tube support, remove the decorative mask on the support, and then refit according to the following two methods depending on the ballast method used by the original fluorescent tube:

1. Inductive ballast

When refitting, first remove the starter s on the light tube support, then remove the two power conductors on the wiring terminals a and B of the inductive ballast in the support, and then short the removed two conductors and disconnect them with an electrician

Wrap it with adhesive tape. In order to prevent the refitted light pipe support from mistakenly installing the general fluorescent lamp, a label shall be pasted in an obvious direction inside the support, indicating that "this lamp basin is only applicable to the LED fluorescent lamp". After checking that the wire connection is accurate, the decorative mask can be installed,

Power on the adapted LED fluorescent tube device to the light tube support.

2. Electronic ballast

The wiring diagram of traditional electronic ballast is shown in Figure 3. When refitting, remove all wires on the electronic ballast terminal in the light tube support, and then short circuit the two wires connecting the terminals a and B of the electronic ballast together and connect them to the "L" at the power input end of the support

The two wires originally connected to the terminals C and D of the electronic ballast are short circuited together and connected to the "n" at the power input end of the support, and finally wrapped with electrical insulating tape. In order to prevent the refitted light tube support from mistakenly installing the general fluorescent tube, it shall be installed on the support

Label the interior in an obvious direction, indicating that "this lamp basin is only applicable to LED fluorescent lamps of the device". After checking that the wire connection is accurate, the decorative mask can be installed, and the appropriate LED fluorescent lamp device can be powered on to the light tube support.
