Description

Technical Field

[0001] The utility model relates to projection equipment, in particular to holographic projection equipment. Background Art

[0002] Holographic projection technology is a type of 3D technology. It originally refers to the technology that uses the principle of interference to record and reproduce the real three-dimensional image of an object. Later, with the guidance of science fiction movies and commercial propaganda, the concept of holographic projection gradually extended to commercial activities such as stage performances and exhibitions. However, the holograms we usually know are often not holographic projections in the strict sense, but a type of holographic projection technology that uses methods such as Pepper's ghost and edge blanking to achieve 3D effects.

[0003] The holographic projection equipment we come into contact with daily usually uses a motor to drive the light strip to rotate, thereby achieving a visual 3D projection effect. However, this type of equipment produces a lot of noise due to its high-speed rotation when working, and when it is fully enclosed in a transparent box, its gas flow is blocked, the machine temperature is prone to being too high, and the light strip is easily disturbed by external light sources, thus affecting the display effect.

[0004] To this end, we propose a holographic projection device. Summary of the invention
