Technical Field
The invention relates to the field of light guiding, in particular to a projector light tube fixing device and a projector.
background
The projector is a device which can project images or videos onto a screen, and can be connected with a computer, a VCD, a DVD, a BD, a game machine, a DV and the like through different interfaces to play corresponding video signals, so that a projection display mode of a large screen is achieved, and excellent presentation and visual effects of a viewer are provided. With the development of electronic technology, projectors are widely used in education, business, and home. The projector may be classified into a cathode ray tube projector (CRT), a liquid crystal projector (LCD), and a digital light processing projector (DLP) according to the operating principle of the projector. The imaging principle of the digital optical processor projector is as follows: the light emitted by the light is transmitted to the digital microscope device in an open state through a plurality of optical elements and is converted into imaging light which is emitted by the projection lens to generate projection influence, namely, the micro-influence is projected onto a huge screen, and sufficient brightness is provided.
In the DLP projector, an optical component Light Pipe (Light Pipe, LP for short) needs to be fixed, and when the Light Pipe runs, the abnormal picture and the reduced contrast are caused, and the image quality is improved. Although some devices for fixing the light pipe exist in the prior art, the problems of complex fixing mode, weak fixing, long process cycle or high cost exist. For example, FIG. 1 is a schematic diagram of a prior art light pipe fixture. As shown in FIG. 1, the device comprises a light pipe cladding 1 'and a cover body, wherein the tail part of the light pipe cladding 1' is provided with an opening 14, and the light pipe cladding is provided with a plurality of glue dispensing parts 15, when the light pipe 4 needs to be fixed, the light pipe 4 is loaded from the opening 14 of the light pipe cladding 1 ', UV glue dispensing is carried out at the position where the glue dispensing parts 15 are partially contacted with the light pipe cladding 1', after the glue dispensing process, the cover body 2 is mounted to the light pipe cladding 1 'at the opening 14 of the light pipe cladding 1', covers the end part of the light pipe cladding 1 ', and finally clamps the light pipe cladding 1' by using a clamping element and then is mounted on a DLP projector shell. Although the fixing device has a simple structure, the UV glue dispensing process has a long period and unstable quality, and the LP position is varied along with vibration and drop; secondly, when the UV dispensing amount is too much, the UV dispensing amount interferes with an external clamping element, so that the problems of infirm fixation and the like are caused; in addition, because lid 2 does not have the fixed mode of gluing and makes lid 2 have the risk of moving back, perhaps lid 2 can take place to warp to can cause the light path to be sheltered from scheduling problem.
