Why does the led light strip suddenly turn off? Three reasons why the LED light strip does not light up:
The light strip is not bright generally can be divided into two situations:
One is that the entire strip of light is off, and the other is that only one section is off.
The former reason may be caused by the power failure caused by the falling off of the plug, or the connector socket is broken, check whether the plug is firmly inserted or not.
The other problem is more common, and the problems may be as follows:
1. Resistance desoldering
2. The light strip is broken
The first two are generally caused by excessive twisting and pulling damage to the light strip during the installation process, so the installation of the light strip must not be too violent.
3. The resistor is burned out and the chip is burned out
Lighting the led strip for a long time leads to overheating. Another possibility is that the led light is burned out due to the voltage. The resistance is broken down due to excessive current or voltage, and the resistance is seriously damaged, so the whole meter of the light does not light up. These are very obvious, generally there will be burn marks, you can check carefully.
Unqualified solder quality:
Before leaving the factory, some manufacturers' led light strips are not qualified. The amount of solder on the light strip is small, and the solder joints are easy to fall off. If the quality of the solder of the light strip is not good, the solder joints of the LED light strip are prone to brittle cracking and falling off during the bending process.
Shipping Damage:
The packaging protection of the led strip is not enough, and the lamp beads may be damaged by impact during transportation. The welding point of the light strip has a phenomenon of virtual welding. The vibration during transportation causes the welding point to fall off and the light strip does not light up.
Broken installation:
1. When the light strip is installed, the bending angle is too large, which causes the solder joint of the LED light strip to separate from the copper foil, resulting in no light.
2. Excessive extrusion of the product when the light strip is installed will cause the LED light strip chip to be damaged or the solder joints to deform and fall off and not light up.
The light strip should not be twisted excessively during installation. If the light strip is squeezed too violently, the solder joints of the LED light strip will fall off or the board will be broken, resulting in no light. A large part of the LED light strip does not light up due to external factors. It is important to cooperate with good manufacturers and avoid buying poor quality LED light strips as much as possible. Before you buy it and install it, test the power on the ground to see if the light strip is damaged, and do not stick it directly to the light trough. If it is not bright, you can communicate with the LED light strip manufacturer. If it is bright, then paste the light strip.
