Problems solved by technology

[0007] However, the above-mentioned structure only uses glue as the only fixing mechanism, and cannot bear the pressure. In addition, it is very easy to change due to the glued part at high temperature, resulting in breakage / displacement / deformation of the glass slide, which reduces the stability and performance of use under high temperature. , and the clamp directly holds the slide, which is more likely to cause damage to the slide and reduce the use time
[0008] In addition, in the above-mentioned device method, the outer surfaces of the slides are clamped by the clamp, but the deformation / displacement / breakage of the slides is easily caused at high temperature, and if the slides cannot withstand the pressure caused by the clamp Otherwise, deformation or breakage will occur, and glass slides of different sizes and shapes cannot be used in different projection systems.
[0009] In addition, even if the reflectors are combined in different ways, the shortcomings still cannot be solved

Abstract

The present invention provides an optical channel device consisting of at least one reflector plate and sleeve, wherein these reflector plates mutually laminated to form one hollow pipe for light passing. Said sleeve covers whole or a part of these reflector plates.

Description

technical field [0001] The present invention relates to a light tunnel module, in particular to a light tunnel module with high stability, no deformation at high temperature, and shareability. Background technique [0002] In a general projection system, a light concentrating system is usually required to uniformly distribute the incident light before exiting. [0003] General projection systems can be divided into image tubes (CRT), liquid crystal projectors (LCD), digital light source devices (DLP) and microdisplays according to different technologies. Please refer to figure 1 , which shows the Chinese Taiwan Publication No. 517855, which is a known digital light source device 10, which has a light source 1, a reflector 2, a color wheel 4, a converging system 3, a lens 5, A digital micromirror device 6 (Digital Micro-mirror Device, DMD) and a lens 7 . The light concentrating system 3 is a hollow pipe, that is, an optical channel, for light to enter and exit. [0004] A...
