Description
Technical field
The present invention relates to a kind of color block module and this projection arrangement that is used for projection arrangement, particularly relate to the modular design of a kind of held stationary color block module on projection arrangement.
Background technology
The widespread usage digital light is handled (Digital Light Processing in digital projection device at present; DLP) technology is as the method that produces digitized video.This technology mainly is to utilize digital micro-mirror device (Digital Micromirror Device; DMD) MEMS (micro electro mechanical system) (MEMS) is the basis, cooperates other a plurality of peripheral optical element exploitations to form.Please refer to Fig. 1, show the decomposing schematic representation of traditional DLP projection arrangement 100 main elements among the figure.This DLP projection arrangement 100 comprises light source 102, colour wheel 104, photoconductive tube 106, lens combination 108, DMD 110 and projection lens 112 etc.Wherein, whole projection arrangement 100 can be divided into two big systems according to the working direction of light, one be light source 102, colour wheel 104, photoconductive tube 106 to lens combination 108, be called illuminator (Illumination System); Its two be from DMD 110 to projection lens 112, be called imaging system (Image System).
Wherein, light carries out the color separation action of Red from light source 102 emissions by colour wheel 104, enters photoconductive tube 106 respectively and carries out the light integration.Light enters DMD 110 through the beam split of a series of lens combination 108 or after closing the effect of light, receive image input signal and make eyeglass (not shown) deflection trickle on it by DMD 110, correct light and image projection can be entered camera lens 112, by camera lens 112 image is presented on the screen (not shown) at last.Compare with the projection arrangement of other principle manufacturing, the DLP projection arrangement has advantages such as high brightness, high contrast, light and handyization.
In known DLP projection arrangement; for asking the demand of whole mechanism moduleization; usually other big the element beyond light source 102, the camera lens 112 is integrated in the ray machine (not shown); and colour wheel 104 also also becomes color block module with fixed mount (not shown) mutual group usually; by locking this fixed mount on ray machine; make colour wheel must be fixed on the interior light path of ray machine, carry out color separation.The fixed form of conventional fixed frame with at least one fixed mechanism, is locked in an end of fixed mount on the ray machine main body.Yet, because being driven by motor, colour wheel 104 runs up, its Revolution Per Minute is usually up to more than thousands of commentaries on classics, even commentaries on classics up to ten thousand.Under high-revolving running like this, known colour wheel is adopted the fixed sturcture of single direction with fixed mount, can produce suitable noise and vibrations, thereby cause DLP projection arrangement main noise source and vibroseis.
In view of this, the noise and the vibrations of being sent because of the colour wheel running when effectively suppressing the operation of DLP projection arrangement, and under the same architecture of controllable costs, finish and transform into, be necessary in fact, in order to do making colour wheel, can guarantee that still the quiet of DLP projection arrangement is with stable in running up down for a long time.
Summary of the invention
A purpose of the present invention provides the color block module that is used for projection arrangement, and this projection arrangement comprises ray machine, and this color block module comprises colour wheel, coupling arrangement and bracing frame.This colour wheel is connected with this bracing frame, this bracing frame comprises first holder and second holder, this coupling arrangement connects this first holder and second holder to this ray machine, and this first holder wherein, with respect to this colour wheel center, must be forward in fact with this second holder is oppositely arranged or is oblique being oppositely arranged and all can, to provide color block module on ray machine, to produce plural at least fixed-direction, to suppress the degree of stability of color block module rotation significantly, noise and vibrations between inhibition and ray machine avoid parts to damage because of vibrations.
Another purpose of the present invention provides a kind of projection arrangement, and this projection arrangement comprises ray machine and aforesaid color block module, is installed on this ray machine.Except making color block module can more firmly be fixed on the ray machine, the noise that also can make the two with cause because of vibrations unstable as to be suppressed significantly, and make the quality of image more stable.
Behind the embodiment of reference accompanying drawing and description subsequently, the person of ordinary skill in the field just can understand other purpose of the present invention, and technological means of the present invention and embodiment.
