Description

Technical Field

[0001] The utility model relates to the field of light strips, and more specifically to an angle-adjustable neon light strip. Background Art

[0002] Neon light strip refers to neon light beads assembled on a strip-shaped FPC (flexible circuit board) or PCB hard board. It is named because its product shape is like a strip.

[0003] Since different occasions such as factories, large warehouses, building corridors and warehouses require different light irradiation angles, a neon light strip with adjustable irradiation angle is needed. A Chinese utility model patent discloses a light strip adjustment device (application number: CN201721412461.5), which includes a mounting plate, a fixing column and a fixing ball. The light strip is mounted on the mounting plate, and the mounting plate is provided with a spherical receiving groove with an opening. The fixing ball is accommodated in the spherical receiving groove. One end of the fixing column is connected to the fixing ball. The arc surface of the fixing ball is spaced along the thickness direction of the mounting plate. A plurality of locking grooves are provided, and a locking assembly which is plugged and fixed with the locking groove is provided on the outer wall of the mounting plate. After the mounting plate is rotated to a more suitable angle around the fixed ball, that is, after the light strip reaches a more suitable illumination angle, the mounting plate is limited by inserting the locking assembly into the locking groove. However, the locking assembly needs to be pulled out and then the mounting plate is rotated, and the position of the locking groove in the spherical mounting groove cannot be seen. The locking assembly often cannot be aligned and inserted into the locking groove, which requires the user to rotate and adjust the mounting plate so that the locking assembly can be inserted into the locking groove, which is very inconvenient.
