Description

[Technical Field]

[0001] This invention relates to the field of rotating luminous and colorful products, and in particular to a low-cost, multi-branch conductive rotating mechanism with outstanding application effects. [Background Technology]

[0002] A projection lamp is a lighting product that uses an LED light source to project a pattern printed on a lampshade or film onto a wall to form a pattern. Traditional projection lamps use a motor to rotate the entire projection lamp, so that the pattern projected onto the wall can rotate. This type of projection lamp is large, consumes a lot of power, has unstable performance, and has relatively limited functions, resulting in a poor user experience.

[0003] For example, the utility model patent with application number CN201520337079.7 and patent title "A Rotating Projection Lamp" specifically protects a rotating projection lamp, including a base, a power supply, a geared motor, LED lights, and a projection lamp cover. The base has a battery box containing a power supply; the battery box surface has a motor mount containing a geared motor with a rotating rod; the geared motor surface has a PCB board with several LED lights; and the rotating rod holds the projection lamp cover. The projection lamp cover has a transparent pattern on its inner wall. This utility model is also encased in a decorative shell, which is independent of the base and can be changed and combined as needed. This utility model achieves a rotating projection effect while reducing power consumption and improving performance.

[0004] For example, utility model patent application number CN202020358169.5, entitled "A Dynamic Projection Lamp," specifically protects a dynamic projection lamp, including a base, a light-emitting element disposed on the base, and a projection film layer. The base also includes a grating layer, a dynamic film layer, and a rotation drive device. The grating layer and the dynamic film layer can rotate relative to each other via the rotation drive device. The dynamic film layer has a pattern that corresponds to the grating of the grating layer. Using the above technical solution, this utility model's dynamic projection lamp has a grating layer and a dynamic film layer disposed on the base that can rotate relative to each other. The dynamic film layer has a pattern that corresponds to the grating of the grating layer. Therefore, during use, the rotation drive device drives the two layers to rotate relative to each other, producing a dynamic pattern display effect, increasing the viewing experience and interest of the projection lamp.

[0005] Existing projection lamp products, especially rotating projection lamp products, generally only use a motor or other rotating drive mechanism to drive the lamp to rotate, so as to achieve the effect of rotating the projected image. The user experience is poor, the function is relatively simple, and it cannot be applied to more occasions, which is quite limiting.

[0006] Therefore, it is necessary to make further targeted improvements and enhancements to the existing design. [Summary of the Invention]
