Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a projection ambient light. Background Technology

[0002] Ambient projection lights are a type of lighting fixture used to create ambiance, and they are frequently used in daily life. Ambient projection lights make it easy for people to create specific atmospheres, greatly facilitating their lives and work. They utilize optical projection principles, employing a high-brightness light source to project images from a projection sheet onto the floor or wall, serving both aesthetic and decorative purposes. To enrich the dynamic lighting effects of ambient projection lights, some models on the market achieve this by controlling the emission of LED chips, but this can affect the lifespan of the LED chips. To address the above issues, Chinese invention patent CN115628429A discloses an ambient projection lamp. This lamp uses a motor assembly to drive a light filter to rotate. The filter includes a first light-transmitting section and a second light-transmitting section surrounding it. The extension lines of the first and second light-transmitting sections intersect. A focusing lens is located above the light filter. Light emitted from one portion of the light source passes sequentially through the first light-transmitting section and the focusing lens, while light emitted from another portion passes sequentially through the second light-transmitting section and the focusing lens, creating projection effects in multiple directions and increasing the projection area to meet customer needs. However, the illumination from the first and second light-transmitting sections in this structure is mainly concentrated in the horizontal and vertical directions. The projection is limited by the first and second light-transmitting sections, resulting in insufficient illumination, uneven light transition, and dark areas, leading to a poor user experience. Therefore, to avoid the shortcomings of the prior art, it is necessary to improve upon it. Utility Model Content

Through the rotatable connection between the lampshade 2 and the lamp holder 1, the connection of the motor shaft of the motor 4 to the planetary gear set, and the gear ring 5 meshing with the planetary gear set on the inner side of the bottom of the lampshade 2, the lampshade 2 rotates stably under the drive of the motor 4 and the planetary gear set, preventing wobbling, ensuring smooth and stable rotation, providing a large illumination area, uniform light transition, avoiding dark areas, stable dynamic lighting effects, extending service life, and providing a superior user experience.

[0024] In a specific implementation, the planetary gear set includes a sun gear 6 connected to the motor shaft of the motor 4.

The LED light source board 3 is mounted on the second support column 9 with screws, which facilitates the fixed installation of the LED light source board 3.

[0026] A hollow projection tube 10 is installed in the middle of the top of the LED light source board 3. The projection tube 10 extends to the top of the lampshade 2. The projection tube 10 is rotatably connected to the lampshade 2, which facilitates the positioning and installation of the lampshade 2 and makes the rotation of the lampshade 2 more stable.

[0027] The top center of the LED light source board 3 has an upward-emitting first LED bead 11. A projection sheet mounting bracket 12 is detachably installed in the middle of the projection tube. The projection sheet mounting bracket 12 is equipped with a projection sheet 22 corresponding to the first LED bead 11. The projection sheet 22 is easy to replace.
