Description

[Technical Field]

[0001] The utility model relates to a strip lamp connection structure. [Background Art]

[0002] In existing strip lamps formed by connecting multiple lamp bodies, the connection ends between the lamp bodies cannot achieve universal rotation. Only one lamp body can rotate relative to another lamp body in a set direction. Therefore, during decoration and installation, the decoration design layout needs to be carried out according to the rotation direction of the lamp, which has great limitations and is not convenient for quick decoration and installation. On the other hand, in existing strip lamps, external extended power cords are required to supply power to each lamp body respectively, resulting in the problem of unsightly exposed power cords. At the same time, during installation or use, the power cords are easily pulled off by external forces or the connection between the power cords and the lamp bodies is pulled off, causing damage.
