As LED applications continue to deepen, LED manufacturers usually solder several LED lighting components. LED strips are formed on a printed circuit board to increase illumination brightness and integration. However, the LED light bar is integrated with the circuit board and is rigid and not easy to bend. This limits the application scenarios of some LED light bars, such as large-size billboards with curved backlights, etc., and it is impossible to directly apply a large LED light. Strip to install. At the same time, the current LED household lamps are basically rigid fixed shapes, such as LED modeling walls, usually with LED light strips covering the entire wall, which has brought some visual pollution for a long time. If you want to replace such LED modeling wall or adjust the LED lighting area, you can only remove the entire LED modeling light strip, re-customize and install. Such LED lighting application not only occupies a limited space in the room, but also is not convenient to install and disassemble. It will bring visual fatigue and aesthetic fatigue for a long time.
