Description

Technical Field

[0001] The utility model relates to the technical field of spotlights, and more specifically, to a rotatable universal spotlight. Background Technique

[0002] Spotlights are typical modern genre lighting without a main light and without a fixed scale, which can create an indoor lighting atmosphere. If a row of small spotlights are combined, the light can form wonderful patterns. Since the small spotlights can be freely rotated, the combined lighting effect is also ever-changing. The spotlight light is soft and luxurious, and it can also provide local lighting to set off the atmosphere.

[0003] The Chinese authorized patent with the publication number of CN216667348U (a floor-standing downlight) designs the downlight as a floor-standing type through a chassis, a lamp pole and a connecting rod, which is convenient for the general public to use the downlight more conveniently. There is no need to drill holes in the ceiling to embed the downlight or arrange a guide rail to install the downlight, which is convenient to use and has a small volume and is easy to move. However, the height of the above-mentioned spotlight is basically fixed, and during use, it is not convenient to adjust the irradiation height of the spotlight according to the use requirements, so the applicability is poor, which is not convenient for the user's use requirements and reduces the practicality of the spotlight. In an existing patent for a spotlight with the patent authorization number of CN 218379196 U, through the mutual cooperation of a hollow rod, a lead screw, a rotating pin, a driving gear, a driven gear, a rotating knob, an internally threaded sleeve and a connecting sleeve, during use, the spotlight can be driven to move up and down by rotating the rotating pin, so as to facilitate the adjustment of the height position of the spotlight according to the use requirements, and the operation method is fast and convenient, which improves the practicality of the spotlight.

[0004] However, in the patent with the authorization number of CN 218379196 U, through the mutual cooperation of a connecting column, a concave sleeve, a damping rotating shaft and a ball, the connecting column is located inside the concave sleeve, and the effect of internal rotation can be realized. Since the spotlight can only rotate according to the axial position of the concave sleeve, the rotation angle of the spotlight is limited, resulting in a reduced area of the light irradiation. Therefore, we propose a rotatable universal spotlight to solve the above problems. Content of the Utility Model
