AI Technical Summary
Existing silicone LED strips suffer from uneven light color and inconsistent light output due to variations in the spacing between the LED beads and the flexible strip during installation. Furthermore, the rigidity of LED strips produced by co-extrusion limits their application.
The design employs a flexible circuit board with bumps and LED beads, combined with opaque colloid and light-diffusing colloid. It maintains stability through reflection distance and uses light-diffusing colloid to transmit light, ensuring optical reflection and uniform light emission.
It achieves more light emitted by the light strip, higher luminous density, and more uniform illumination. The flexible light strip has consistent color and no shadows after bending and deformation, thus solving the problem of uneven light color.
