Background technique

Starlight is a type of product in projection equipment. Through the design of the light path, the light source is transmitted and illuminated on the projection film, so that the content on the projection film is put on the wall or curtain, resulting in a visual experience of moving starry sky.

The existing star lights have two ways, one is to place the projection sheet directly above the tray gear, and the tray gear drives the projection sheet to rotate together; the other is that the projection sheet is fixed with the tray gear and mounted on the tray as a component. On the top, the projection film is driven by the tray gear to rotate together. However, in the first method above, there is no fixed relationship between the projection film and the tray gear, so there is a risk of the projection sheet falling off when the tray gear rotates, and when the starlight is tilted, the projection sheet and the tray gear will be partially disengaged , causing skew and affecting the projection effect. In the above-mentioned second method, the tray gear has no relevant constraints in the vertical direction, and gear jumping is likely to occur during the transmission of the tray gear, which affects the projection experience effect.

Therefore, the existing star lights have defects such as insufficient stability and single vision, resulting in poor projection effects of the star lights, affecting the user's experience, and being unfavorable for the popularization and use of the star lights.
