Abstract
The utility model discloses a ground hemispherical projection device. The ground hemispherical projection device comprises a cabinet body and a projection screen arranged on the cabinet body, wherein a lamp tube or an imaging device is arranged in the cabinet body, the beam from the lamp tube or the imaging device converges or diverges on the projection screen, and the projection screen is in a convex or concave spherical or arc structure. The ground hemispherical projection device is easy to use, realizes the multi-angle view and interaction; and can be arbitrarily placed, and not subject to site constraints.
Description
Technical field
The utility model relates to a kind of ground semispherical projection device.
Background technology
Traditional product or display and demonstration screen, all the plane curtain by a light beam and imaging forms, because vision at ordinary times, a lot of visitors can only watch interaction in a direction.And a light beam projecting is on the curtain of plane, when having the visitor to be not intended to block light beam, all can not imaging on the curtain of whole plane, and cause visual loss and bring defective.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of easy to use, can multi-angle view and admire interactive ground semispherical projection device.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of ground semispherical projection device, comprise cabinet and be arranged at projection screen on described cabinet, be provided with fluorescent tube or video imaging instrument in described cabinet, the light beam of described fluorescent tube or video imaging instrument is assembled or is diverged on described projection screen, and described projection screen is sphere or the arcuate structure of epirelief or indent.
As the further optimization of technique scheme, described projection screen is transparent or semitransparent material.
The beneficial effect main manifestations of a kind of ground of the utility model semispherical projection device is: easy to use, can multi-angle view and admire interactive; And can arbitrarily place, not limited by the place.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of the utility model a kind of ground semispherical projection device.
Fig. 2 is the plan structure schematic diagram of the utility model a kind of ground semispherical projection device.
Embodiment
