Description
Technical field
The present invention relates to six axial adjustment of the mosaic screen projective technique field DLP more particularly to DLP mosaic screen light engine projects
Device and its method of adjustment.
Background technique
DLP mosaic screen is to be imaged by realizing on light engine projects to dedicated projection screen, and make the figure projected
As being just displayed on the screen with the equirotal complete scale of projection screen, just to the standard of the position of projector itself
True property proposes very high requirement, and in order to reach this requirement, universal in the market is all the device for using six axial adjustment platforms,
Light engine is mounted on above the platform, and this six axial adjustment platform can be moved forward and backward, and is moved left and right, is moved up and down, X-axis
Rotation, Y-axis rotation, Z axis rotates to be adjusted on six direction, and light engine is enabled accurately to position large screen.
Currently on the market it is mainly multiple screws by manually adjusting six axial adjustment platforms, also has and adjusted respectively by motor
The adjustment that each screw realizes the position of platform is saved, due to the central point of the adjustment of six axial adjustment platforms and the projection light of projector
Central point it is not consistent, X, Y, the rotation of Z axis can change the left and right of platform, front and back, upper and lower relative position, thus both
Method have the shortcomings that one it is obvious, be exactly it is time-consuming very long, need to adjust repeatedly, it is time-consuming and laborious, especially manually adjust accuracy
It is also weak, while one man operation is inconvenient, is adjusted after film viewing screen before need to shielding.There is also the dresses to six axial adjustment platforms for another postorder
The maintenance set.
It is cumbersome etc. to ask the purpose of the present invention is overcoming regulating time existing for existing six axial adjustment platform adjustment mode long
Topic, present invention employs a kind of adjustment methods, light engine is connect with control box, and light engine can pass through cabinet light
Road design be positioned directly in projection imaging it is substantially all over the screen under conditions of, operator only needs to operate by remote controller, in adjustment
Pattern is set, adjustment intermediary operation personnel operate while observing before screen, save a large amount of adjustment manpower and time.
Summary of the invention
