1. The required length of the light strip should be made in advance and rounded. If it is 4.4 meters, it must be 5 meters. Why? Because the light strip is a unit of 1m, it will not affect the circuit only if it is cut off from the incision. If you cut it off at will, a unit will not light up.
2. The plug with the lamp interface cannot be reversed.
The optical band is not a very LED diode, and it is driven by DC, so it has positive and negative poles. If the positive and negative poles are reversed, the light strip will not light up. . If the connecting plug is not energized, just remove the other end of the light strip.
3. Place the light strip correctly
Most of the light strip is the original packaging of the coil, and the newly removed light strip will be distorted and difficult to install. You can tidy them up first and put them in the light trough.
Because the light strip is single-sided, uneven placement will lead to uneven light and shade, especially at the corner.
4. Pay attention to the installation environment
Most of the light strips are installed in the grooves around the ceiling, and the dust in the grooves must be cleaned up, because the dust is easy to cause open fire accidents when heated.
Second, matters needing attention
1. When the whole roll of light strip is unpacked or piled into a ball, don't electrify the light strip, because the magnetic field and heat brought by the coil are strong, which will cause fire.
2. When cutting the light bar according to the installation length, you can only cut it at the place marked by the scissors, otherwise one of the units will not light up.
3. Only ribbons with the same specification and voltage can be connected in series, and the total length of series connection shall not exceed the maximum allowable length.
4. When connecting the power supply or connecting two light bars in series, bend the lantern head left and right first, so that the wires in the light bars are exposed for about 2-3 mm, cut them clean with scissors without burr, and then connect them with pins to avoid short circuit.
5. When the light strips are connected in series with each other, try to light one section for each connection, so as to find out in time whether the positive and negative electrodes are connected incorrectly and whether the light emitting directions of the light strips are consistent.
The installation of ceiling lamp strip can be completed in three steps. Of course, the installation should also pay attention to specifications. Everyone should also pay attention to some precautions above to ensure smooth installation. Finally, safety issues need attention, and safety comes first.
