<p>LED panel light is also called LED panel light, which has the advantages of beautiful appearance, environmental protection and energy saving. Today, the editor Dolight will analyze the 4 common problems of <a href="https://www.dolight-led.com/led-panel-lights" rel="noopener noreferrer" target="_blank">LED panel lights</a> with everyone.</p><p><br></p><p>1. Package failure</p><p>Refers to the quality degradation of components caused by incorrect packaging design or production process. The epoxy resin material used in the package will deteriorate during the use of the LED panel light, which will reduce the service life of the LED panel light. It can also cause problems such as refractive index, light transmittance, hardness, expansion coefficient, air permeability, water permeability, and filler function.</p><p><br></p><p>2. Chip failure</p><p>Refers to the failure of the chip itself or other causes that constitute the failure of the chip. This is how LED panel light manufacturers control the low price of LED panel lights by purchasing very poor quality chips.</p><p><br></p><p>3. Electrical overstress failure</p><p>That is, if the LED light source is used in overcurrent (EOS) or electrostatic shock damage (ESD) to the chip, it will constitute an open circuit of the chip, resulting in electrical overstress failure.</p><p><br></p><p>4. Thermal overstress failure</p><p>The important factor that affects the optical properties of LEDs has always been temperature. This is because if the temperature of the solder joints of the package pins increases under the premise that the thermal resistance of the LED system remains unchanged, the junction temperature will also increase, which will cause the LED to fail prematurely. </p><p><br></p>
