[0002] A projection lamp is a device that uses optical principles and advanced projection technologies to project images, bringing a more vivid and realistic visual experience to fields such as commerce, education, and entertainment.

[0003] Most existing projection devices use transparent or semi-transparent lamp shades and achieve the projection effect through built-in light-emitting components and projection mechanisms. However, when these devices are used in specific environments (such as outdoors, with a lot of dust, etc.), there are problems such as being easily interfered by external light and the internal devices being easily contaminated. At the same time, for devices that need to achieve dynamic projection effects, such as slide projection lamps, most existing technologies achieve this through manually replacing slides or using complex mechanical structures, which are cumbersome to operate and have poor effects.

[0004] Therefore, the inventor is committed to designing a projection lamp to solve the above problems. Summary of the Utility Model
