Description
Technical field
The present invention relates to a kind of imaging system, the simple and easy and convenient thin part device of adjusting wherein of particularly a kind of energy makes the focusing of imaging and the imaging system that the position is used for the ray machine of projector equipment all more accurately.
Background technology
Back-projection system commonly used, according to the ray machine technology, be broadly divided into silicon liquid crystal (Liquid Crystal onSilicon, LCOS) and digital light handle (Digital Light Processing, DLP) two kinds of patterns, wherein again the built-in digital micro-mirror device of factor word optical processing (Digital Micromirror Device, DMD), so image appearance is good, become the projector equipment of main flow.
Fig. 1 is the ray machine schematic perspective view that typical reflective digital light is handled (DLP) projector equipment.Image is after light-source system 190 produces, behind colour wheel 191 and light accumulation column, promptly inject prism apparatus 120, after handling by the digital micro-mirror device (not shown) of prism apparatus 120 belows, the image prism apparatus 120 of passing through that can turn back, be projected on the large-sized mirror (not shown) by projection lens device 140, on display screen, project again at last.Wherein, prism apparatus 120, digital micro-mirror device and projection lens device 140 regions generally are referred to as imaging system 150.
Fig. 2 is the structural representation that typical penetration digital light is handled projector equipment, mainly is made of ray machine body 210, projection lens device 240 and light-source system 290.Digital light is handled projector equipment and is produced light beams by light-source system 290, again by ray machine body 210 with the image of finishing dealing with, be projected to screen by projection lens device 240.Projector equipment through accurate the adjustment after, and assemble in the mode of error minimum, just can make image be in best focus state, and in accurate position imaging.
Handling projector equipment with the penetration digital light is example, it regulates the technology of image focusing and position, be earlier light-source system 290 to be locked in an end of ray machine body 210 with screw, projection lens device 240 temporarily is fixed on the ray machine body 210, and " progressively " adjust the relative position of 290 of projection lens device 240 and light-source systems, make image focusing and picture position moderate, with screw projection lens device 240 is locked on ray machine body 210 again.The factor that this manual adjustment need be considered is a lot, and the utmost point expends time in, and when fixing two parts with screw, packing strength easily makes the good spacing of former adjusted change, and causes the position to produce error once again, makes the final picture quality of projection arrangement be difficult to control.If being applied to reflective digital light, handles on the ray machine of projector equipment this manual adjusting style, because of the formation of its light and image device is more complicated, so the difficulty of adjusting will more be difficult to overcome.
In view of above restriction, industry proposes another again and uses the mode that tool is regulated image focusing and position of adjusting, its step is for to be assembled in projection lens device 240 on the ray machine body 210 with screw, utilize again and adjust tool adjustment light- source system 290 and 240 relative positions of projection lens device, make the focal length and the position optimization of projected image, with a glue fixed form light-source system 290 is installed on the ray machine body 210 at last, makes three's relative position constant.This uses adjusts the adjustment of tool (not shown), again in the fixing mode of a glue, though make 240 relative positions of light-source system 290 and projection lens device more easy to control, but need design in addition because of adjusting tool, and its operational program is comparatively complicated, it is uneconomical on the contrary make to adjust the activity duration, and fixedly the time used special heat-resisting durable some glue cost very high and in case gluing fixing after, does not promptly have again row and restores the possibility of row adjustment again; For expending on the integrated artistic cost, lose economization on the contrary.
For effectively reaching the adjusting of image focusing and position, and the release program is complicated, the activity duration is long, cost is high and the disappearance of the difficult keyholed back plate of technology, a kind of output that improves imaging system, make the ray machine of projector equipment, image quality before it dispatches from the factory can be adjusted to optimum state easily, make the product quality after dispatching from the factory more stable, just become for this reason industry to need the target of reaching badly.
Summary of the invention
Main purpose of the present invention, promptly be to provide a kind of imaging system that is used for the ray machine of projector equipment, by the relatively laterally sliding relation between prism apparatus in the Adjustment System and ray machine body, and its prism apparatus is remained unchanged in fact with the relative fore-and-aft distance of digital micro-mirror device, the focal position of this system imaging can accurately be adjusted easily, not only reduce assembling or maintenance man-hours, also reduce production cost.
Secondary objective of the present invention, promptly be to provide a kind of imaging system that is used for the ray machine of projector equipment, by the relative laterally sliding relation between the prism apparatus in the Adjustment System and digital micro-mirror device, the picture position of this system imaging can accurately be adjusted easily, not only reduce assembling or maintenance man-hours, equally also reduce production cost.
