Common problems in the installation process of LED panel lights
What are the common faults of LED panel lights due to improper operation? The following is specifically for the four problems that arise in the installation and use of LED panel lights, and summarize the following experience:
1. Electrical overstress failure problem
is the LED panel light source if overcurrent is used (EOS) or electrostatic shock damage (ESD) to the panel light chip, thus forming an open circuit of the panel light chip, resulting in electrical overstress failure.
2. Thermal overstress failure problem
Most important factors affecting the optical properties of LEDs are caused by high temperature. This is due to the fact that under the premise of constant thermal resistance of the LED system, if the temperature of the pin solder joints in the LED packaging operation increases, the junction The temperature will also increase, and then cause problems with the optical performance of the LED, resulting in a bad phenomenon in the LED lighting.
3. LED panel light package failure problem
Package failure refers to the quality damage of electronic components caused by packaging design innovation or unreliable product production process. The epoxy resin material used in LED panel light packaging will have aging problems in daily use, which will cause the LED panel light The service life is reduced, and it may even cause problems such as refractive index, light transmittance, hardness, expansion coefficient, air permeability, water permeability, and filler function that affect the lighting effect.
4. LED panel light chip failure problem
The LED panel light chip itself fails or other reasons constitute the panel light chip failure. This is why some manufacturers of LED panel light purchase very unreliable LED chips. This is also a wrong direction to control costs. Panel light LED lamp manufacturers LED as a lighting source has been widely used in many fields, including landscape lighting market, automobile market, traffic light market, special general lighting, safety lighting and special lighting, etc., production and sales of various LED indoor and outdoor LED lamps , Products include LED panel lights, LED tubes, fluorescent tubes, LED ceiling lights, downlights and other products
