Description
Technical field
Optical extinction reflector plate that is high the present invention relates to a kind of reflectivity and can eliminating ultraviolet light, more particularly to one kind include
The back-projection system of the DLP large-screen splicing screens of the optical extinction reflector plate.
Background technology
Existing speculum is using the glass for being coated with reflectorized material on one side, generally silvered glass mirror or aluminum plating glass
Mirror, silvered glass mirror is generally the original sheet glass of float glass mirror grade or polished glass plates one layer of silver layer, then plates one layer of copper,
Again plus one layer of mirror back lacquer is as protection；Aluminized mirror is the silver layer that glass behind is replaced with aluminium layer, but reflective due to aluminized mirror
Rate does not have the height of silvered mirror, and is easier to the silver of metalling run out for hemstitching occur, being exactly commonly called as, and reflects in clarity compared to silvered mirror
Also it is poor, therefore, now in the case of having higher requirements to reflecting rate or clarity, generally all use silvered mirror.
The reflectivity of silvered mirror can reach 92%~94%, and silvered mirror is generally used in existing back-projection system, but
It is, with the raising of development and the requirement of technology, due to the reflection action of glass in traditional silvered mirror, the reflectivity of silvered mirror
The requirement is not achieved, is badly in need of a kind of reflective mirror of requirements at the higher level.
In the light sent out in projector, containing a large amount of ultraviolet light, since ultraviolet light can not pass through glass, so, no
Have ultraviolet light and overflow back projection equipment, damage to the health of personnel, still, ultraviolet light can to pass through biochip or
Organic film, if using organic film or biochip in back-projection system, ultraviolet light can pass through reflective mirror, to the personnel after reflective mirror
It damages.
In addition, due to the glass substrate that silvered mirror uses, diaphanous spot is susceptible in process of manufacture, when being reflected into
When showing on screen, it may appear that stain influences display effect；It during carrying, is easier to damage, the back side is easily
There is cut, and in back-projection system and other equipment during installation and debugging, the dynamics of dismounting is difficult to hold, easily reflective mirror
Crushing.
Invention content
The technical problems to be solved by the invention are to provide a kind of reflectivity height and are not easy impaired optical extinction reflection
Piece, meanwhile, additionally provide a kind of back-projection system for including the optical extinction reflector plate.
Technical scheme of the present invention is specific as follows：
A kind of optical extinction reflector plate, which is characterized in that including：(1) reflecting layer, the tree of the water white transparency of an electroplate
Fat piece I；(2) include the extinction layer of ultraviolet light extinction material；(3) the silver-plated table that both sides are bonded in resin sheet I respectively is further included
Face and the adhesive layer I of delustring layer surface.
Resin sheet is high relative to the light transmittance of glass, and light is because the loss amount of reflection will lack, and therefore, this optical extinction is anti-
Piece is penetrated relative to traditional silvered mirror, reflectivity will height；It, can be by delustring after ultraviolet light passes through the silver layer on resin sheet I
Ultraviolet light extinction material on layer sponges, and prevents ultraviolet light from passing through, and ultraviolet line pollution is caused to outside；Simultaneously as this light
Learning the middle of delustring reflector plate uses resin sheet to have instead of sheet glass by strong anti-extrusion ability, and can effectively prevent from transporting
Damage during use to silver coating.
It advanced optimizes, the edge of the silver-plated surface of the resin sheet I is equipped with the closing for protruding from silver-plated surface
Flange.
Silver coating such as oxidation by air can lead to the lace of reflector plate, and silver coating is aoxidized in order to prevent, and needing will be silver-plated
Layer and air exclusion, this optical extinction reflector plate are sealed back using adhesive completely, the oil that more traditional silvered mirror uses
The method of paint, seal is more preferable, but the seal of silver coating edge is poor, in order to more completely by silver coating and air
Isolation, the present invention use the design of flange, can enhance the leakproofness of edge, silver coating is separated completely with air.
It advanced optimizes, the upside that the flange is equipped with its cross section is jagged striated structure.
It is so designed that, leakproofness can be further enhanced.
It advanced optimizes, the extinction layer is equipped with the resin sheet II of ultraviolet light extinction material, and adhesive for a surface
Layer I is bonded on the surface equipped with ultraviolet light extinction material.
It advanced optimizes, adhesive layer II is additionally provided with outside the extinction layer, adhesive layer II is externally provided with the modeling of chemical fibre software
Glue-line.
The design of chemical fibre soft plastic layer can enhance the overall flexibility of this optical extinction reflector plate, primarily serve stretching resistance
Effect.
It advanced optimizes, the chemical fibre soft plastic layer is built in for textile cloth in soft plastic.
It advanced optimizes, the chemical fibre soft plastic layer is equipped with multiple holes.
The design in hole can make the bonding of adhesive layer II and chemical fibre soft plastic layer more firm, enhance whole flexible
Property and tensile strength.
It advanced optimizes, the resin sheet I and resin sheet II are PVC pieces.
It is anti-including above-mentioned optical extinction meanwhile the present invention also provides a kind of back-projection system for DLP mosaic screens
Piece is penetrated, other components are same as the prior art.
This optical extinction reflector plate has the advantages that reflectivity is high and it is impaired to be not easy, simultaneously, moreover it is possible to effectively eliminate purple
Outside line prevents from damaging human body.It can be widely applied in the equipment for requiring high reflectance.
This back-projection system has the advantages that reflecting rate is high, does not have ultraviolet line pollution.
