Abstract
The utility model relates to a projection screen, in particular to a reflective orthographic projection screen, which comprises a shell, a spacing frame and a reflective screen surface which is arranged in the shell and is spaced by the spacing frame. The utility model is characterized in that the reflective screen surface is made to be concave inwards to take a sphere crown shape and a carbon nano powder coating, a nano metal powder layer, a rare earth metal nano powder layer, a substrate layer, an epoxy resin layer and a fluorocarbon coating are sequentially arranged on the reflective screen surface of the composite layer. By adopting the structure, the utility model mainly solves the technical problem that the existing reflective orthographic projection screen is not provided with the condensing effect and the brightness of the existing reflective orthographic projection screen can not still satisfy people due to the relation of the shape of the screen surface and provides a product with good condensing effects whose screen surface is acid and alkali-resistant, waterproofing and dustproof.
Description
Technical field:
The utility model relates to projection screen, particularly a kind of reflective front projection screen.
Background technology:
Reflective front projection screen is the vitals of projector equipment, also is the support equipment of equipment such as projector, projection TV set, projector.Along with the widespread use of computer technology, go into education, culture, academic exchange, video conference, command centre, all be all trades and professions and every field such as analog simulation with the supporting large screen projection equipment stride of computing machine in every field.The supporting most soft screens that adopt of current and projector are so because literal and drawing that optical loss reflects greatly are all darker, and result of use is poor, the indoor necessary low light level has influenced observing effect greatly.One of solution is to adopt high-quality high-brightness projection screen efficiently, and the metal screen is one of first-selection.At present, reflective front projection screen mainly is by shell, limitting casing and is positioned at shell and by the spacing reflection panel of limitting casing, this reflection panel can be the plane, sphere or cylinder.Though its appearance has solved above-mentioned problem to a certain extent, owing to the shape relation of panel does not have the optically focused effect, its brightness still can not be satisfactory.In addition, also need to solve problems such as panel acid and alkali-resistance, waterproof and dustproof.
The utility model content:
The utility model will solve existing orthogonal projection radiation shield does not have the optically focused effect owing to the shape relation of panel, and the technical matters that its brightness still can not be satisfactory provides the product of the good and panel acid and alkali-resistance of a kind of spotlight effect, waterproof and dustproof.
For solving the problems of the technologies described above, the utility model is achieved in that
A kind of projection radiation shield, comprise shell, limitting casing and be positioned at shell and by the spacing reflection panel of limitting casing, it is characterized in that: this reflection panel indent is one spherical, and the reflection panel of this composite bed is followed successively by carbon nanometer powder coating, nano metal powder layer, rare earth metal nanometer powder layer, substrate layer, epoxy resin layer and fluorine carbon coat from top to bottom.
The reflection panel of this 120-150 inch, catercorner length are 304-381 centimetre, and recess bow height is 5.7-9.0 centimetre.
Major advantage of the present utility model is:
1, screen of the present utility model adopts the spherical cap-shaped structure of indent, is that its optically focused performance is better than original planar shaped, sphere shape and cylinder shaped screen, and the brightness of screen is better.
2, the utility model adopts the reflection panel of composite bed to be followed successively by carbon nanometer powder coating, nano metal powder layer, rare earth metal nanometer powder layer, substrate layer, epoxy resin layer and fluorine carbon coat from top to bottom, makes this panel have technique effects such as acid and alkali-resistance, waterproof and dustproof.
Description of drawings:
Fig. 1 is the front view of the utility model projection radiation shield.
Fig. 2 is the cut-open view of A-A direction among Fig. 1.
Fig. 3 is the partial enlarged drawing at B position among Fig. 2.
Among the figure:
1-shell; 2-limitting casing;
3-reflection panel;
31-carbon nanometer powder coating; 32-nano metal powder layer;
33-rare earth metal nanometer powder layer; 34-substrate layer;
35-epoxy resin layer; 36-fluorine carbon coat.
Embodiment:
See also Fig. 1,2,3, it is the structural representation of the utility model projection radiation shield.As shown in the figure, it comprises shell 1, limitting casing 2 and is positioned at shell 1 and by the spacing reflection panel 3 of limitting casing 2.
These reflection panel 3 indents are one spherical, and therefore, the image imaging face has certain geometric buckling, and with the human eye spherical crown surface, the curvature of pupil imaging is similar.The reflection panel 3 of this composite bed be followed successively by from top to bottom carbon nanometer powder coating 31,, rare earth metal nanometer powder layer 33,, epoxy resin layer 35 and fluorine carbon coat 36.Wherein, nano metal powder layer 32 mainly is made of as diffuse surface metals such as Al, Ag.Substrate layer 34 can become spherical by polycarbonate (PC), tygon sheet materials such as (PE, PP) heat back in mould, and product specification has 72 inches, 84 inches, 100 inches, 120 inches etc., and oversize has fiberglass cold conditions layer to cover to form.
If this reflection panel 3 is 120-150 inches, then its catercorner length is 304-381 centimetre, and it is 5.7-9.0 centimetre that recess bends height.
Claims (2)
1, a kind of projection radiation shield, comprise shell (1), limitting casing (2) and be positioned at shell (1) and by the spacing reflection panel (3) of limitting casing (2), it is characterized in that: this reflection panel (3) indent is one spherical, and the reflection panel (3) of this composite bed is followed successively by carbon nanometer powder coating (31), nano metal powder layer (32), rare earth metal nanometer powder layer (33), substrate layer (34), epoxy resin layer (35) and fluorine carbon coat (36) from top to bottom.
