摘要： Provided in the present disclosure is an ambient image projection device, which includes a light source assembly, a first projection mechanism and a second projection mechanism provided side by side; the first projection mechanism includes a display and a first optical module, a content played on the display is guided by the first optical module to form a dynamic image to be projected in space; the second projection mechanism includes an interference lens and a second optical module, light emitted from the light source assembly is guided by the second optical module to pass through the interference lens and forms an interference pattern to be projected in space; the interference pattern and the dynamic image overlap at least partially with each other in the space. The disclosure provides more stereoscopic dynamic visual experience by projecting images via a display, which is less costly as compared with the prior art and can provide a richer and more diverse image selection, and can significantly improve the user experience.

摘要： Provided in the present disclosure are an interference lens (1) and a projection ambient lamp. The interference lens (1) includes: an interference sheet (11) with a first surface (12) and a second surface (13) opposite to the first surface, the first surface (12) being a rough surface; and a reflective film (14) provided at the interference sheet (11); wherein light is reflected by the reflective film (14) to form an interference pattern. The projection ambient lamp includes the foregoing interference lens (1), a light source (2) and a focusing lens (3); light emitted from the light source (2) passes through the interference lens (1) and is reflected by the reflective film (14) to form an interference pattern, which is focused by the focusing lens (3) and projected on a medium. The present disclosure realizes simplification of the structure by providing a reflective film at the interference lens, and does not need to provide individual reflector and refractive lens as compared with the prior art, hence utilization of light energy is higher, power consumption is lower, manufacturing cost is lower, and projection effect is better.
