1. First, remove the ordinary fluorescent tube from the fluorescent tube bracket and store it well, then remove the decorative cover on the bracket, and then according to the ballast form used by the original fluorescent tube.

2. When refitting, first remove the up-converter S from the lamp bracket, then remove the two power lines on the terminals A and B of the inductive ballast in the bracket, and then short the removed two lines. Wrap it with electrical insulating tape.

3. In order to prevent the refitted fluorescent tube bracket from being mistakenly installed with ordinary fluorescent tubes, a label should be attached at a conspicuous position inside the bracket, indicating that "this lamp basin is only suitable for installing led fluorescent tubes". Only after checking that the wires are connected correctly can the decorative mask be installed, and the appropriate led fluorescent tube can be installed on this light tube bracket to be electrified and lit.

Extended data:

Some customers design the lamp board first, and then look for the power supply, and find it difficult to have a suitable power supply, or the current is too large and the voltage is too small (for example, I & gt350 mA, V & LT40V);

Either the current is too small, or the voltage is too high (such as me

Generally, the rated working current of LED is 20 mA, and some factories have used it up at the beginning and designed it as 20 mA. In fact, the working heat is very serious at this current. After many comparative tests, the design of 16- 18 mA is ideal. Total current of n parallel circuits =17 * n;

Generally, the recommended working voltage of LED is 3.0-3.6V After testing, most LEDs work at 3. 125V, so the formula of 3. 125V is more reasonable. The total voltage of M bulbs in series = 3.125 * m.
