Description
Technical field
The present invention relates to guide-lighting field, in particular to a kind of projector light pipe fixing device and projector.
Background technique
Projector is a kind of equipment that can be projected image or video on screen, can be same by different interfaces
Computer, VCD, DVD, BD, game machine, DV etc., which are connected, plays corresponding vision signal, reaches the Projection Display side of large screen
Formula provides viewer splendid presentation and visual effect.With electronic technology development, projector be widely used in education, business and
In family.Cathode ray tube projection instrument (CRT), liquid crystal projector (LCD) sum number can be divided into according to projector's working principle difference
Code optical processing projector (DLP).The wherein image-forming principle of digital optical processor projector are as follows: the optics that optics issues passes through
Multiple optical elements be transferred to numerical digit microscope equipment in the open state be converted to image optics by projection lens project with produce
Raw projection influences, i.e., projects to minor impact on jumbo screen, and provide enough brightness.
Optical element light pipe (Light Pipe, abbreviation LP, light pipe) needs to fix in DLP projector, when light pipe is run
When dynamic, picture exception and contrast is caused to reduce, video imaging quality.Although there are also fix to light pipe in the prior art
Device, but that there are fixed forms is complicated, is not fixed firmly, the problems such as CT Cycle Time is long or higher cost.For example, Fig. 1 is existing
There is a kind of light pipe fixture structure schematic diagram present in technology.As shown in Figure 1, the device includes light pipe coating member 1 ' and lid
Body 5, the tail portion of light pipe coating member 1 ' is equipped with opening 16, and is equipped with several dispensing portions 17 in light pipe coating member, when needs are to light
When pipe 4 is fixed, light pipe 4 is packed into from the opening 16 of light pipe coating member 1 ', in 1 ' part of dispensing portion 17 and light pipe coating member
The place of contact carries out UV glue point glue, after the dispensing processing procedure, then by lid 5 at the opening 16 of light pipe coating member 1 '
Installation coats the end of light pipe coating member 1 ', finally clamps light pipe coating member 1 ' using clamping element, so to light pipe coating member 1 '
After be arranged on DLP projector shell.Although the fixture structure is simple, since UV glue point glue CT Cycle Time is long, product
Matter is unstable, and LP falls with vibration and made a variation in position；Secondly, can be generated with external clamping element when UV dispensing amount is excessive
Interference, causes the problems such as being not fixed firmly；In addition, since the fixed form for dispensing glue of lid 5 makes lid 5 have the wind retreated
Danger or lid 5 can deform, to will cause the problems such as optical path is blocked.
