Extension 440a and lower extension 440b defines an accommodation space 444, light valve module 450 can insert extension 440a and under
Between extension 440b, for example upper and lower two sides and extension 440a, 440b that make light valve module 450 form superimposed relationship,
May be defined as light valve module 450 in space in the term of this " superimposed relationship " can project along horizontal or vertical direction projection
At least part of extension 440a, 440b, or extension 440a, 440b can along horizontal or vertical direction projection in space
Project at least part of light valve module 450.In the present embodiment, the optical module of moving part 410 can be located in framework 440,
Coil 422 can be located between framework 440 and the optical module of moving part 410, and framework 440 can carry inner full-reflection prism 460
(inner full-reflection prism 460 is coated by framework 440), enable light-path adjusting mechanism 400 assemble after position closer to interior
Portion's total reflection prism 460.Figure 16 B are the schematic diagram of the light-path adjusting mechanism of another embodiment of the present invention.As shown in fig 16b, light
Road adjustment mechanism 400b framework 440 can include a ledge arrangement in the extension that the one end for closing on light valve module 450 is formed
440c, and light valve module 450 can insert the opening 446 that ledge arrangement 440c corrals go out, that is, ledge arrangement 440c can be with light valve
At least two sides of module 450 form superimposed relationship, enable the position after the assembling of light-path adjusting mechanism 400 closer to inside
Total reflection prism 460.Understand that framework 440 only need to correspond to light in the one end for closing on light valve module 450 based on foregoing individual embodiments
Valve module 450 forms breach or extension, and breach or extension can define the sky of accommodating at least part light valve module 450
Between, you can obtain the position allowed after the assembling of light-path adjusting mechanism 400 and be able to the effect closer to inner full-reflection prism 460.
Figure 17 A are that the light-path adjusting mechanism of another embodiment of the present invention is arranged in pairs or groups the component decomposition maps of other optical modules, figure
17B is side view and schematic top plan view of Figure 17 A light-path adjusting mechanism after assembling.As shown in Figure 17 A and Figure 17 B, light path is adjusted
Complete machine structure 400c light-shielding structure can be an independent anti-dazzling screen 448, and anti-dazzling screen 448 may be disposed at framework 440 and other light parts
Between (such as light valve module 450, inner full-reflection prism 460), light valve module 450 is avoided in closed mode (OFF state)
Reflected light or system veiling glare irradiation system other components cause temperature raise or contrast decline the problems such as.Figure 17 C
For according to one embodiment of the invention, display anti-dazzling screen 448 and light valve module 450 and the schematic diagram of inner full-reflection prism 460.Such as figure
Shown in 17C, because independent anti-dazzling screen 448 is without the condition limitation for being located in framework 440 or connecting framework 440, therefore in layout type
There is larger design flexibility in state, in an embodiment, the distributed areas of anti-dazzling screen 448, the visual light valve module of size
450 closed mode (OFF state) reflected light and the main configuration that position optimizes of haunting of system veiling glare, to enter one
Step lifting light shielding effect.In each embodiment of the present invention, the form of light-shielding structure does not limit completely, such as can be a screening
Light portion, an anti-dazzling screen, a shading piece etc. are without limiting.Furthermore in an embodiment, such as anti-dazzling screen 448 or light shielding part
At least a portion of 440d light-shielding structure can form superimposed relationship with an inner full-reflection prism (or mirror lens) 46.
It should be noted in above-mentioned each embodiment, such as the component of light valve module and inner full-reflection prism is only to illustrate, example
As inner full-reflection prism can be substituted by field lens, speculum or mirror lens, and when light-path adjusting mechanism applies to different optics
System or when being arranged at the diverse location of optical system, light-shielding structure (such as light shielding part 440d or anti-dazzling screen 448) is equally available
To cover do not share the same light unnecessary light or veiling glare caused by part.Furthermore the material of light-shielding structure does not limit, such as it can be modeling
Glue or metal, and if light-shielding structure formed by the Heat Conduction Material of such as metal, light-shielding structure also for example may extend to contact light
Valve module 450 assists the function of the radiating of light valve module 450 to provide.In addition, light-shielding structure also adjusting and external form to make
For the aperture between light valve module 450 and projection lens (not shown), or lid can be used as on ray machine to provide dust-proof effect.
The Individual features mentioned by each embodiment of the present invention are should be noted, are not only capable of applying to illustrate or describe this feature
Embodiment in, that is, this feature can operate with each other embodiment or the non-illustrated change of other specifications of the present invention
Example is without limiting.For example, Figure 15 A embodiment shows that framework 440 has a breach 442 and light-shielding structure 440d, but its
Do not limit, have breach 442 framework 440 can also arrange in pairs or groups as shown in Figure 17 A not with framework 440 link independent anti-dazzling screen
448.Or in another embodiment as shown in figure 18, eyeglass 212 can be located at the load of such as eyeglass seat 214 by leaf spring 232
On body, and two are not attached to coil group 222 and can be respectively arranged at two diagonal sides of eyeglass seat 214 independently of one another.
