What are the common failures of office lighting due to improper operation?

The linear light is an ultra-thin, energy-saving, environmentally-friendly, and safe LED lighting fixture. This panel light uses the new LED light source technology and is well received by consumers. An energy-saving, environmentally-friendly and safe lighting fixture that enterprises pay attention to can completely replace the existing traditional Panel lighting, office lighting has the advantages of good color consistency, multiple optional color temperatures, high brightness, long life, low energy consumption, and environmental protection.

        The following specifically addresses the four issues that arise in the installation and use of office lighting, and summarizes the following experiences:

        1.Line lamp package failure

        Packaging failure refers to the damage to the quality of electronic components caused by packaging design innovation or unreliable product manufacturing process. The epoxy resin materials used in line lamp packaging will cause aging problems in daily use, resulting in the life of line lamps. Reduction may even cause problems such as refractive index, light transmittance, hardness, expansion coefficient, air permeability, water permeability, filler function, etc. that affect the lighting effect.

2.Line lamp chip failure

        The line lamp chip itself fails or other reasons constitute the failure of the panel light chip. This is the case where some line lamp manufacturers purchase LED chips with very unreliable quality, which is also a wrong direction to control costs.

        3.Electrical overstress failure

        That is, if the line lamp light source is used in the overcurrent (EOS) or electrostatic shock damage (ESD), the panel lamp chip is formed, thereby forming an open circuit of the panel lamp chip, resulting in electrical overstress failure.

        4. Thermal overstress failure

        The important factor that affects the optical properties of LEDs is in most cases caused by excessive temperature. This is because under the premise that the thermal resistance of the LED system is unchanged, if the temperature of the pin solder joints in the LED packaging operation increases, Temperature will also rise accordingly, and then cause problems with the optical performance of LEDs, resulting in bad LED lighting.
