Why did the LED strip light suddenly stop lighting up?
Why does the LED strip light suddenly stop lighting? Three major reasons why LED strip lights do not light up:
The strip light does not light up generally can be divided into two situations:
One is that the entire strip light is off, and the other is that only one section is off.
The former reason may be caused by a power outage due to the plug falling off, or the connector socket is broken. Just check whether the plug is firmly inserted or whether it is broken.
The other kind of problem is more common and may cause the following problems:
1. Resistor desoldering
2. Broken board of strip light
The first two are generally caused by excessive twisting and pulling during the installation process, so the strip lights must not be installed too violently.
3. The resistor is burned out and the chip is burned out.
Lighting the LED strip light for a long time leads to overheating. Another possibility is that the LED light is burned out due to voltage reasons. The resistor is broken down due to excessive current or voltage, and the resistor is seriously damaged, so the entire meter of light does not light up. These are very obvious, and there are usually signs of burnt out. You can check them carefully.
Solder quality is unqualified:
Before leaving the factory, some manufacturers' LED strip lights were substandard. The strip light has a small amount of solder and the solder joints are easy to fall off. If the solder quality of the LED strip light is not good, the solder joints of the LED strip light may easily crack and fall off during the bending process.
Shipping damage:
The packaging protection of LED strip lights is not enough, and the lamp beads may be damaged by impact during transportation. The welding points of the strip light have weak soldering. The vibration during transportation caused the welding points to fall off and the strip light did not light up.
Broken installation:
1. When the strip light is installed, the bending angle is too large, causing the solder joints of the LED strip light to separate from the copper foil, resulting in no light.
2. Excessive squeezing of the product during the installation of the strip light may cause the LED strip light chip to be damaged or the solder joints to deform and fall off and not light up.
The strip light should not be excessively twisted during installation. If the strip light is squeezed too violently, the solder joints of the LED strip light will fall off or the board will be broken, resulting in no light. A large part of the reason why LED strip lights do not light up is due to external factors. It is important to cooperate with good manufacturers and avoid buying poor quality LED strip lights as much as possible. Before you buy it and install it, test the power on the ground to see if the strip light is damaged. Do not stick it directly to the light slot. If it does not light up, you can contact the LED strip light manufacturer. If it is bright, then attach the strip light.
