Abstract
The utility model relates to a double film reflecting screen. The utility model is mainly composed of a base (an organic plate or organic film), a metal aluminum film and a scattering film; namely, the first layer of film of the upper surface of the base adopts the metal aluminum film, the second layer of film is a semi-transparent high aggregation scattering film which has scattering particles and is coated on the upper surface of the metal aluminum film of the first layer, and the reflecting screen is provided with curves in the horizontal direction and the vertical direction to form a non-spherical reflecting structure. The utility model has the characteristics of high gain (high brightness) and wide visual angle; the double film structure adopted by the utility model not only overcomes the defects of difficult operation and inconvenient cleaning existing in the original similar products but also performs the function of protecting the screen. The utility model has the advantages of low cost and convenient operation, so the utility model is a novel and practical reflecting screen.
Description
The utility model relates to a kind of reflective viewing screen, particularly a kind of reflective viewing screen that two film layer structures are arranged.
Radiation shield at present commonly used generally can be divided into two kinds of diffusion type (fabricbase curtain type) and directional types (metal single layer overlay film type).The former visual angle is wide but gain little to be that brightness is low, must to use in darker environment, though latter's gain is big, the high visual angle of brightness is very narrow, but thereby range of observation then very little.The modified of now existing metal single layer overlay film screen, it mainly is to utilize multiple complex surfaces treatment process, thereby makes metallic diaphragm produce a kind of scattering film increase of striped surperficial oxidized formation simultaneously visual angle.The radiation shield of this structure is complex process not only, and the anti-environment capacity of oxidation film layer on surface is relatively poor, can not direct cleaning but also exist, use shortcomings such as inconvenience.
The purpose of this utility model then is the metallic reflection screen that a kind of pair of film layer structure type is provided at the existing defective of above-mentioned radiation shield.Promptly be provided with two membranes above the substrate, and its vertical and horizontal direction all there is bending, to form an aspheric surface reflection configuration at it.The utility model not only has high-gain (high brightness), and wide visual angle, but also direct cleaning treatment are less demanding to environment for use, and price is low, characteristics easy to use.
The purpose of this utility model is realized by following measure: two rete radiation shields adopt organic plates or organic membrane substrate, metallic diaphragm and scattering rete to form.First tunic on substrate adopts the metallic aluminium rete, aluminum membranous layer to be provided with the irregular high density longitudinal fluting of length (depression striped) striped staggered mutually on the surface, this tunic mainly plays reflex is distributed in perpendicular on the groove direction luminous energy, even vertical incidence light produces orienting reflex, glancing incidence light produces scattered reflection.Second tunic above the substrate is to adopt to cover on ground floor metallic aluminium rete to add a floor height polymerization scattering rete again; this scattering rete is the semitransparent thin film of band scattering particulate; molecule particle in this rete makes reflection ray produce saturating diffuse scattering in the certain angle scope; thereby form bigger field angle, second layer scattering film also plays the effect of protection aluminium film simultaneously.The vertical and horizontal direction of radiation shield all has bending, forms an aspheric surface reflection configuration, and this structure makes reflection luminous energy more concentrated, has improved the brightness and the homogeneity of picture.
Fig. 1 is a general structure diagrammatic cross-section of the present utility model;
Fig. 2 is the schematic perspective view that the utility model bends to non-spherical structure.
Below by accompanying drawing structure of the present utility model and manufacturing process are described further.
1 is substrate among Fig. 1, mainly plays a part to support rete, and substrate 1 can be organic plates or organic membrane.Covering first tunic that adds on substrate 1 is metallic aluminium rete 2, thickness is generally in 0.1 millimeter, on the surface of film is the depression striped perpendicular to horizontal direction of pressing mill to form through machinery, the varying length of striped, and the degree of depth that is highdensity its depression of depression striped is generally about 10 microns, horizontal spacing between the striped does not wait yet, and generally remains in 5 millimeters.
On metallic aluminium rete 2, cover again and add the organic translucent scattering rete 3 that one deck has the scattering particulate; its thickness generally remains in 0.05 millimeter; has high transmittance; molecule particulate in its rete plays scattering process to reflection ray; the substantivity contact can be carried out in the surface simultaneously; be convenient to handle and cleaning, so this tunic also plays the effect of protection screen when playing scattering process.
4 is front elevations of non-spherical structure among Fig. 2, the 5th, the vertical view of non-spherical structure, the 6th, the side view of non-spherical structure, according to calculating relatively, adopt the radiation shield of aspherical shape reflection configuration, after handling with this kind mode, the brightness of projection imaging will further improve because of the optically focused reflection, and horizontal direction adopts different flexibility to make with vertical direction to observe the visual effect that uniformity degree of image improves and meet the people.
In sum, the utility model compared with prior art has following advantage:
1, the utlity model has high-gain (high brightness), wide visual angle, and environment for use is wanted Ask not high characteristics.
2, the substantivity contact can be carried out in the utility model surface, thereby cleaning is extremely convenient.
3, the scattering rete of the utility model employing not only can increase the visual angle, but also plays the effect of protection screen.
4, compared with similar products, the utility model price is low, cost performance is high, and practicality is stronger.
Claims (4)
1, a kind of pair of rete reflective viewing screen, form by organic plates or organic membrane substrate, metallic diaphragm and scattering rete, it is characterized in that first tunic on substrate (1) adopts metallic aluminium rete (2), second tunic is to cover to add a floor height polymerization scattering rete (3) on ground floor metallic aluminium rete (2) again, this scattering rete is organic semitransparent thin film of band scattering particulate, the vertical and horizontal direction of reflective viewing screen all is made as bending, forms an aspheric surface reflection configuration.
2, according to said pair of rete reflective viewing screen of claim 1, the surface that it is characterized in that described ground floor metallic aluminium rete (2) is provided with the irregular highdensity longitudinal fluting of length, the groove striped is not staggered mutually, this tunic mainly plays reflex, and luminous energy is distributed in perpendicular on the groove direction, even vertical incidence light produces orienting reflex, glancing incidence light produces scattered reflection.
