Description

Technical Field

[0001] The utility model relates to the technical field of strip track lights, in particular to a line light with adjustable illumination angle. Background Art

[0002] Many commercial spaces currently use track strips and various types of track lights for primary and accent lighting. However, after installation, the majority of existing track lights cannot adjust their illumination angle, making them inadequate for optimal use in the environment. The few adjustable linear lights, however, experience unstable self-locking and fixed angles (loosening and causing them to sag and illuminate the ground), making them prone to loosening and unable to maintain the desired illumination angle for long periods of time.
