Description
Technical field
The present invention relates to projection art, particularly to a kind of lens assembly and projector.
Background technology
Along with the continuous progress of science and technology, projection display technique was developed rapidly in recent years.Wherein,
The advantages such as short out-of-focus projection is little due to required projector distance, and projected picture is big and become recent research emphasis.
At present, it is achieved a kind of mode of short out-of-focus projection is reflective short out-of-focus projection.I.e. by projection lens by shadow
As being incident upon on curved reflector, via on curved reflector to projection screen.
As it is shown in figure 1, the structural representation that Fig. 1 is lens assembly of the prior art, of the prior art
The upper end of reflecting mirror 03 is fixedly attached on main casing 02 by straight crossbeam, and the upper end of reflecting mirror 03 leads to
Crossing screw to be fixed on crossbeam 01, lower end is fixed on main casing 02 by regulation screw.But, when instead
Penetrate after mirror fixed, be likely to result in the change of the reflection angle of curved reflector, and then projection picture occurs
Picture offsets, and On Local Fuzzy, or the most reciprocity problem in image focusing position affect Projection Display quality, at this moment
Being accomplished by being adjusted the installation site of curved reflector, when carrying out tightening screw, crossbeam is the most outside
Deforming upon under power effect, crossbeam deforms and the installation site causing reflecting mirror is also changed, impact
The drop shadow effect of projector, if not adjusting, also will affect the drop shadow effect of projector.
