Summary of the invention
In order to change the lamp box advertisement form of the present content dullness of subway platform, solve video frequency projector simultaneously and use the screen image desalination problem that exists as the projection advertising equipment, the invention provides a kind of technical scheme of high brightness projection advertisement device at subway platform.
Technical scheme of the present invention is: adopt high-brightness reflective material as projection screen, the replacement advertisement lamp box is installed on the wall in the underground railway track outside, advertisement projector is installed in the height of setting the inboard platform of underground railway track top projection is carried out in screen; Because 0 ° of this projection screen watches the angular brightness reflection coefficient high, the passenger that waits during to the projection screen top view, will see advertisement picture very bright on the projection screen on platform; This picture has the reflecting brightness height, color rendition is good, and clear picture is bright, the strong characteristics of penetrating sense, and picture is not only desalinated under the interference of surround lighting, can produce the attracting especially sight of distinguished advertising results on the contrary.Therefore, utilize high-brightness reflective material to manufacture projection screen, need not to adopt the more high-power projector of high brightness, just can solve the projected image desalination problem that video frequency projector runs into when subway platform uses.
Technical scheme of the present invention realizes by following measure: a kind of high brightness projection advertisement device at subway platform, form by the advertisement projector 3 that is fixed on 1～100 width of cloth picture frame screen 2 on underground railway track 4 outside walls 5 and is installed in platform 6 one side equivalent amounts.Picture frame screen 2 has adopted high-brightness reflective material 1 to make, and its physical dimension is 80～250 o'clock; High-brightness reflective material 1 has reflecting brightness height, characteristics that resolving power is strong, and watching the angular brightness coefficient at 0 ° is 150～1800, the image resolving power be 50～400 lines right/mm, thickness is 0.01～8mm; Above the inboard platform 6 of underground railway track 4, advertisement projector 3 is installed in subway name of station lintel plate 7 inboards, corresponding with picture frame screen 2, the setting height(from bottom) of advertisement projector 3 is apart from 1.8～3.5 meters on platform 6 ground, and its picture dimension that projects to picture frame screen 2 on the wall 5 of the outside is 80～250 o'clock.
Because the space between subway carriage and the name of station lintel plate 7 is limited, thus advertisement projector 3 is adopted vertical vertical installation, and before projection lens 8, installed catoptron 9 additional, so that the refraction image direction.
The invention has the beneficial effects as follows: the general brightness projector that utilizes some panel height brightness picture frame screens and equivalent amount, formed the video frequency projection advertisement device that can connect the multimedia and the network equipment at subway platform, the advertising lamp box that has replaced the picture dullness, improved the technical merit of tube advertising device, make the advertizing content of subway platform become rich and varied, allow the passenger that waits in the limited time, see advertising message more, that upgrade.Simultaneously, this video frequency projection advertisement device with lamp box advertisement compare, not only saved the making and the maintenance cost of lamp box, and need not to adopt the more high-power video frequency projector of high brightness, just can create huge advertisement economy benefit.
