Projector based on holographic projection technology

Abstract

The invention discloses a projector based on a holographic projection technology, and relates to the technical field of projection equipment, in particular to a projector based on a holographic projection technology, which comprises a projector body, wherein a projection port is formed in the front surface of the projector body; a projection lamp is arranged in the projection port; a protection partition plate is arranged on the front surface of the projection lamp; side face heat dissipation holes are formed in the side face of the projector body; and back face heat dissipation holes are formed in the back face of the projector body. The protection partition plate is arranged on the front face of the projection lamp, when the projection lamp is turned on, an electromagnet is energized togenerate magnetic force to push the protection partition plate rightwards to enable the projection lamp to project normally, and when the projection lamp is turned off, the electromagnet is unenergized, the magnetic force disappears, and the protection partition plate moves leftwards under pushing of the reset spring to seal the projection lamp. Dust is prevented from falling onto the projection lamp, the safety of the projection lamp is protected, and the projection lamp is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of projection equipment, in particular to a projector based on holographic projection technology. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. 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 sci-fi movies and commercial promotion, the concept of holographic projection gradually extended to commercial activities such as stage performances and exhibitions. But the holography we usually know is often not a holographic projection in the strict sense, but a kind of holographic projection technology that uses methods such as Pepper's phantom and edge blanking to achieve 3D effects.

AI Technical Summary

Problems solved by technology

[0003] Projectors project images or video screens through projection lamps. During use, if the surface of the projection lamp is contaminated with dust, it will affect the clarity of the projection. Existing projectors use projection covers to protect the projection lamp. Manually cover the projection cover, which is troublesome to use. At the same time, the existing projector is not convenient to adjust the height of the projection, and the accuracy of the impression projection. Moreover, the interior of the projector is relatively tight parts, which is very easy to be affected by vibration. And damage, for this we provide a projector based on holographic projection technology
