Abstract
The utility model relates to a high brightness spherical reflecting screen. The utility model belongs to the spherical reflecting screen which is formed by that the bottom plate of the spherical screen is coated with directional reflecting coating or metal reflecting cloth. When the high brightness spherical reflecting screen of the utility model is used, sharp and non-deformed images are displayed at each part of a silver screen, and meanwhile, viewing is carried out from any angle and screening is carried out in bright indoor places.
Description
The utility model belongs to the projection screen of projector.
The utility model is patent " the reflective screen of high brightness arc " improvement (CN93237256.2).The reflective screen of high brightness arc is horizontal arcs of recesses screen, and when the smaller and screen of radius-of-curvature was bigger, the image of marginal portion was just clear inadequately up and down.
The purpose of this utility model is to provide a kind of any angle to watch each several part in the screen all to manifest the reflective screen of high brightness of picture rich in detail.
The reflective screen of the utility model high brightness sphere is that to adopt reflectorized material to be coated with or to overlay on the projector camera lens be the reflective screen of sphere on the concave spherical surface screen base plate of spherical radius to the distance of screen.
The reflective screen of the utility model high brightness concave spherical surface can strike out concave spherical surface with sheet metal, also can make concave spherical surface screen base plate with fiberglass by mould, then coated with reflectorized material, promptly makes the reflective screen of high brightness sphere.
Adopt the reflective screen of high brightness sphere of the present utility model,, can be adjusted to lens focus because the projector camera lens is equal to the each point distance of screen.Therefore, watch in any one angle, each several part can both the clear showing image in the screen.
Accompanying drawing is an embodiment of the reflective screen of high brightness sphere.
It is the sphere that foursquare every chord length of 4040mm is 1600mm that embodiment 1 usefulness fiberglass is made the radius of a ball, sprays directional reflective coating (military chemical plant, geographical lake, Chinese Academy of Sciences Nanjing research institute capital produces) then and promptly makes the reflective screen of high brightness sphere.This kind screen by day or lamplit indoor, projection projection or magic lantern are watched in any angle, can both see indeformable clearly image.And screen light is soft, and is not dazzling.
Embodiment 2, with the 1.5mm cold drawing strike out the square that the radius of a ball is 4040mm, every chord length is the sphere of 1600mm, with viscose glue metal reflective cloth (production of green hill, Jiangyin City, Jiangsu Province reflective cloth factory) is sticked on calmly and promptly makes the reflective screen of high brightness sphere on this sphere then.
Claims (3)
1, the reflective screen of a kind of high brightness sphere is characterized in that being coated with or overlaying on the projector camera lens with reflectorized material is the reflective screen of sphere on the screen base plate of concave spherical surface of the radius of a ball to the distance of screen.
2, the reflective screen of sphere according to claim 1 is characterized in that it can being to be sprayed on the reflective screen of the sphere of making on the screen base plate with directional reflective coating.
3, the reflective screen of sphere according to claim 1 is characterized in that it can being to stick on the reflective screen of the sphere of making on the screen base plate with metal reflective cloth calmly.
