Four common problems and malfunctions of LED Back-lit Panel Light


LED Back-lit Panel Light, also known as LED panel light, has the advantages of beautiful appearance, environmental protection and energy saving. Today, I will analyze with you the 4 common problems of LED Back-lit Panel Light.

   1. Package failure

Back-lit Panel Light
   refers to the deterioration of component quality caused by incorrect packaging design or production process. The epoxy resin material used in the package will deteriorate during the use of the Back-lit Panel Light, which will reduce the service life of the LED Back-lit Panel Light. It can also cause problems such as refractive index, light transmittance, hardness, expansion coefficient, air permeability, water permeability, and filler function.

   2. Chip failure

   refers to the failure of the chip itself or other reasons that constitute the failure of the chip. This is how LED Back-lit Panel Light manufacturers control the low price of LED Back-lit Panel Light by purchasing very poor quality chips.

  3. Electrical overstress failure

   is that if the LED light source is used in overcurrent (EOS) or electrostatic shock damage (ESD), the chip will be damaged, which will cause the chip to open and cause electrical overstress to fail.

  4. Thermal overstress failure

The important factor that affects the optical properties of LEDs has always been temperature. This is because under the premise that the thermal resistance of the LED system remains unchanged, if the temperature of the solder joints of the package pins increases, the junction temperature will also increase, and then cause LED Back- lit Panel Light expires early.
