发明名称 Message Projection System
摘要 A message display that produces a visible message by projecting an image on a surface such as a wall or floor. A bright light source is provided, preferably including an array of light emitting diodes (“LED's”). The light from this bright source is passed through one or more lenses in a condenser assembly to make it more uniform. The light then passes through an image plate that contains a small version of the image to be displayed. Once the light passes through the image plate it next passes through a focusing assembly. The focusing assembly creates a desired projected image on a target surface such as a wall or floor. The projected image is a representation of the image contained on the image plate.

主权项 1. A method for displaying a message on a target surface, comprising: a. providing a message projector, including, i. a light source,ii. a projection axis,iii. an image plate lying on said projection axis, said image plate having a first side and a second side, wherein said image plate includes a clear portion corresponding to said message,iv. a condenser assembly lying on said first side of said image plate between said light source and said image plate, said condenser assembly directing light emitted by said light source through said image plate,v. a focusing assembly lying on said second side of said image plate, said focusing assembly configured to focus said light passing through said image plate on said target surface; b. attaching said message projector to a fixed external object, with said projection axis being directed toward said target surface; and c. activating said light source so that said light from said light source passes through said image plate, through said condenser assembly, through said focusing assembly, and out along said projection axis, said light forming said message on said target surface.
