Description

Technical Field

[0001] This utility model relates to the field of LED lamp production technology, specifically to a flexible LED light strip bending degree detection device. Background Technology

[0002] Flexible LED light strips are an innovative product widely used in lighting and decoration, popular for their exceptional flexibility and malleability. Compared to traditional rigid lighting fixtures, flexible LED light strips can be easily bent and folded, allowing them to adapt to various shapes and spatial layouts. Their applications are wide-ranging, covering residential, commercial, and landscape lighting, creating a variety of lighting effects. The bending degree testing of flexible LED light strips is particularly critical; accurate bending degree testing ensures the performance stability of the light strip during use.

[0003] Utility model patent CN212410035U discloses a bending degree detection device for the production of flexible LED light strips that allows for multiple comparisons. The device includes an operating table and a handle. A vertical plate is welded to the upper left of the operating table, and a first lead screw and a connecting plate are disposed inside the vertical plate. The first lead screw is connected to the inside of the connecting plate. A pressure plate is installed on the right side of the connecting plate. The handle is installed at the top of the first lead screw. Limiting plates are provided on the left side of both the second top plate and the first top plate. In this bending degree detection device for the production of flexible LED light strips that allows for multiple comparisons, the left end of the pressure plate is connected to the connecting plate, and the connecting plate is threadedly connected to the first lead screw. The length of the pressure plate is the same as the length of the horizontal plate, which is connected to a fixing plate. Both the horizontal plate and the fixing plate have connecting grooves inside, facilitating the clamping and fixing of one end of multiple light strips. The other end of the light strip is movable, ensuring the normal operation of the light strip detection work.

[0004] While the existing technologies described above can detect the bending degree of flexible LED light strips, the obstruction of the vertical plate and the need for a pressure plate to fix the left end of the light strip limit the detection to the portion near the left end. This limitation prevents the detection of bending degrees at any point on the light strip, thus presenting a limitation in usability. To address these issues, we propose a flexible LED light strip bending degree detection device that enables flexible detection at any position on the light strip, improving both efficiency and accuracy.
