Example Embodiment

[0023] See figure 1 , figure 1 Shown is a schematic diagram of a projector according to the present invention. The present invention provides a projector 1. The projector 1 includes a casing 101 and a light pipe module 2, a light source module 102, and an optical engine 103 housed in the casing 101. The light pipe module 2 can pass through The first positioning member is fixed on the body of the optical engine 103. The main function of the light pipe module 2 is to homogenize the light projected from the light source of the light source module 102 of the projector within the body and guide the light source into parallel light with a rectangular cross section. The projector 1 generates an image by projecting parallel light onto the optical engine 103, and projects it onto a wall or a target through a lens.

Abstract

The invention discloses a light guide pipe module and a projector with the same, wherein the light guide pipe module comprises a shell, a light-transmitting element and a light guide pipe; the shell is provided with a first end and a second end which are arranged oppositely; the first end is provided with a first opening and a clamping hook extending from the shell; the second end is provided with a second opening; the light-transmitting element is arranged in the shell from the first end; a first surface of the light-transmitting element abuts against the second end and covers the second opening completely; the light guide pipe is provided with a through hole; when the light guide pipe enters the shell from the first end, the through hole corresponds to the second opening, the end part of the light guide pipe abuts against a second surface of the light-transmitting element, and the clamping hook and the light-transmitting element limit the light guide pipe to move in the first direction, wherein the first direction is the direction from the first end to the second end; and the first surface is opposite to the second surface. The light guide pipe module and the projector disclosed by the invention have the advantages that sand and dust are isolated and the assembly is convenient.

Description

technical field [0001] The present invention relates to a light pipe module and a projector, in particular to a light pipe module capable of isolating sand and dust and easy to assemble and a projector with the light pipe module. Background technique [0002] The projector has the advantages of large-size images and easy portability, and has become the best image display device for office presentations or home theaters. A traditional projector includes a light source module, a light pipe module (Light pipe Module), an optical machine housing and a digital micromirror device (Digital Micromirror Device, DMD). The light source module is installed in the optical machine housing, and provides light source, and the light pipe is assembled on the optical machine housing. The light pipe module has a light pipe, which is one of the important optical components in the projector. The main function of the light pipe is to homogenize the light projected from the light source module ins...
