Abstract

A pico projector of the invention includes an illuminating module, an imaging module, and a lens-focusing module. The illuminating module is configured to emit light. The imaging module is configured to add picture messages into the light to generate an image and project the image. The lens-focusing module is configured to regulate a focal length of the imaging module.

First claim

What is claimed is:

1 . A pico projector, comprising:
an illuminating module configured to emit light; an imaging module configured to add picture messages into the light to generate an image and project the image; and a lens-focusing module configured to regulate a focal length of the imaging module.

2 . The pico projector as claimed in claim 1 , wherein the illuminating module, the imaging module and the lens-focusing module are joined by grooves, screws, mortises, latches and/or adhesive.

3 . The pico projector as claimed in claim 1 , wherein the illuminating module is a single light source module, a double light source module, a triple light source module or a laser light source module.

4 . The pico projector as claimed in claim 1 , wherein the imaging module comprises a display panel configured to add the picture messages into the light and a lens through which the image is projected, and the lens- focusing module is configured to regulate a focal length of the lens.

5 . The pico projector as claimed in claim 4 , wherein the lens is a long focus lens or a short focus lens.

6 . The pico projector as claimed in claim 1 , wherein the lens-focusing module is a lateral focusing module, a front focusing module, a bottom focusing module or a top focusing module.

7 . The pico projector as claimed in claim 1 , wherein the lens-focusing module is a manual-regulating focusing module or an electro-regulating focusing module.

8 . The pico projector as claimed in claim 1 further comprising one or more complementary module connected to the illuminating module, the imaging module, and/or the lens focusing module.

9 . The pico projector as claimed in claim 8 , wherein the complementary module comprises a reflective mirror module, a light engine protecting cover, or a heat dissipation module.

10 . The pico projector as claimed in claim 8 , wherein the illuminating module, the imaging module, the lens focusing module and the complementary module are joined by grooves, screws, mortises, latches and/or adhesive.
