Common Problems in the Installation Process of LED Panel Light

What are the common faults of LED panel lights due to improper operation? The following is a summary of the following experiences for the four problems in the installation and use of LED panel lights.

Ⅰ. Electrical overstress failure of LED panel lights

If the LED panel light source is used during overcurrent (EOS) or electrostatic shock (ESD), the chip of LED panel light will be damaged, resulting in an open circuit of it, resulting in electrical overstress failure.

Ⅱ. Thermal overstress failure of LED panel lights

An important factor affecting the optical properties of LEDs is mostly caused by excessive temperature. This is due to the fact that under the premise that the thermal resistance of the LED system remains unchanged, if the temperature of the lead solder joints in the LED packaging operation increases, the junction temperature will also increase, and then cause problems in the optical performance of the LED, leading to damage to the LED lighting.

Ⅲ. Packaging failure of LED panel lights

Package failure refers to the quality damage of electronic components caused by package design innovation or unreliable product production process. The epoxy resin material used in the package of LED panel light will have aging problems in daily use, which will reduce the service life of the LED panel light, and even cause the refractive index, light transmittance, hardness, expansion coefficient, air permeability, Water permeability, filler function and other issues that affect the lighting effect.

Ⅳ. The problem of chip failure of LED panel light

The failure of the chip of LED panel light or other reasons constitute the failure of the panel light chip. This is why some led panel light manufacturer purchase LED chips with very unreliable quality. This is also a wrong direction to control costs.
