    1. Poor Conductivity

    • Cause: The current cannot flow smoothly through each LED bead.
    • Solution: Inspect and secure the strip wiring to ensure unimpeded electrical flow.

    2. Inconsistent LED Bead Quality

    • Cause: Variations in manufacturing can lead to different power outputs among beads.
    • Solution: Select LED strips with uniform bead quality to ensure consistent power across beads.

    3. Overly Long LED Strips

    • Cause: The resistance in longer strips can make bulbs further from the power source dimmer.
    • Solution: Divide long strips into shorter sections, each with its own power supply.

    4. Improper Use

    • Cause: Incorrect handling during installation or use can affect light distribution.
    • Solution: Follow correct installation procedures and avoid excessive bending or compressing the strip.

    5. Ambient Light Interference

    • Cause: The intensity of room lighting can affect the LED strip's light output.
    • Solution: Consider ambient light levels and choose strips with appropriate brightness.

    6. Incorrect Installation Position

    • Cause: The positioning of the strip can impact the distribution of light.
    • Solution: Adjust the strip's installation position to alter light distribution.

    8. Connection Line Problems

    • Cause: Poor connection lines can impede electrical current.
    • Solution: Inspect and repair the strip's connection lines to ensure they are secure.

    9. Surface Contamination

    • Cause: Dust or dirt on the strip's surface can affect light scattering.
    • Solution: Regularly clean the strip surface with a soft cloth.

    10. Brightness and Color Temperature Adjustment

    • Cause: Brightness and color temperature settings may not suit the current environment.
    • Solution: Adjust the strip's brightness and color temperature for the desired lighting effect.

    11. Raising the LED Strip

    • Cause: High light slots may prevent the light from the LED strip from being visible.
    • Solution: Raise the LED strip to maintain a distance of about 4-5 cm from the top edge of the light slot.
