Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a spotlight that can rotate stably 360 degrees. Background Technology

[0002] Spotlights are a general term for spotlights with a small beam angle. They project a beam of light with a narrow beam angle, have strong focusing ability, high illuminance, and produce a strong beam effect. They can be used as ceiling lights, stage lights, etc. Spotlights are commonly used lighting fixtures in daily life. The light from a spotlight shines directly on the object to be emphasized, highlighting it. The adjustment of the spotlight's beam angle directly affects its lighting effect. However, current spotlights mainly rely on the mounting bracket for angle adjustment, lacking an angle adjustment mechanism within the spotlight itself. The rotation angle adjustment is limited and unstable, making spotlights inconvenient to use and affecting their lighting effect, resulting in unsatisfactory performance. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content
