Image projection device, and method for manufacturing image projection device

A method for manufacturing an image projection apparatus, comprising:

• connecting a first snap-fit piece disposed at a first optical component and a second snap-fit piece disposed at a second optical component in a snap-fit fashion to assemble the first optical component and the second optical component integrally;
• and
• providing a lighting assembly configured to emit a light beam, wherein the first optical component is configured to allow light emitted by the lighting assembly to pass through, and the second optical component is configured to allow the light passing through the first optical component to pass through,
• wherein the method further comprises:
• providing an image generation module, wherein the image generation module is configured to allow the light emitted by the lighting assembly to pass through and cause the light beam that passes through to carry image information, wherein the image generation module comprises a plurality of image generation submodules distributed in a cross section of the light beam, an image generation submodule being configured to cause a sub-light beam passing through the image generation submodule to carry image information;
• wherein one of the first optical component and the second optical component comprises at least one compound eye,
• wherein the at least one compound eye comprises a first compound eye, wherein the first compound eye comprises a plurality of compound-eye units distributed in the cross section of the light beam, the compound-eye unit of the first compound eye is configured to project a sub-light beam carrying image information and passing through the image generation submodule;
• or
• wherein the at least one compound eye comprises a first compound eye and a second compound eye, wherein the first compound eye and the second compound eye respectively comprise a plurality of compound-eye units distributed in the cross section of the light beam, wherein compound-eye units of the first compound eye and the second compound eye that correspond to the same image generation submodule are configured to project a sub-light beam carrying image information and passing through the image generation submodule.

An image projection apparatus, comprising:

• a lighting assembly, configured to emit a light beam;
• and a first optical component, configured to allow light emitted by the lighting assembly to pass through,
• wherein the image projection apparatus further comprises:
• a first snap-fit piece, disposed at the first optical component;
• a second optical component, configured to allow the light passing through the first optical component to pass through;
• a second snap-fit piece, disposed at the second optical component, and adapted to be connected with the first snap-fit piece in a snap-fit fashion to assemble the first optical component and the second optical component integrally;
• an image generation module, configured to allow the light emitted by the lighting assembly to pass through, and cause the light beam that passes through to carry image information, and
• at least one compound eye;
• wherein one of the first optical component and the second optical component comprises the at least one compound eye;
• wherein the first snap-fit piece is disposed at an outer periphery of the at least one compound eye in a radial direction of the light beam, one of the first snap-fit piece and the second snap-fit piece comprises a protrusion, and the other one of the first snap-fit piece and the second snap-fit piece comprises a snap groove or a snap hook.
