Now the solution to this problem has come, just a simple holographic film, glass windows into advertising window, the projection content is perfectly presented on the left and right sides of the window. In the rear projection program, the lamp body in the inside, the human vision in the outside, can avoid the limitations of the installation, but also do not need to consider the outdoor waterproof problem.

The holographic film was first used with a projector, but the brightness of the projector is usually around 3000-5000 lumens, even in the evening when there is no light at all the effect is also general, not to mention the use of the daytime. But the projection lamp lumens easily up to 20,000 lumens or more, and then supporting the rotation of water and other special effects, the projection screen can be clearly visible during the day, to the night is lifelike, if you use the semi-permeable holographic film can also reflect the three-dimensional effect Oh!

Projection lamp, although temporarily unable to achieve dynamic effects, but can be used in rotating mode to show the enterprise’s promotional patterns and some basic text information, compared with the current posters, more colorful and full of a sense of technology, especially the replacement of the pattern only need to replace the LOGO piece can be, saving the installation trouble.
