ABSTRACT:
An illuminated three message sign is provided with improved illumination from the exterior of the vanes at the apices away from the sign surface exposed for message display. The sign has a message display side and an array of triangular rotating sign message displays. Each of the three sides of the triangular message displays in combination a message with corresponding sides of the other sign message displays. When the array of triangular sign message displays has the message surfaces of one of the arrays parallel to the display side, the sequential message is displayed. The apices of the sign message displays are each provided with cylindrical lenses. These cylindrical lenses register to slit light sources. By the expedient of providing a slit light source for each rotating message display, sequential illumination is provided as each message of the array rotates for viewer presentation. Additionally, an insert is disclosed for placement between an illuminated three message sign and fluorescent bulbs mounted interior of an illuminated menu box. This insert is provided with cylindrical lenses, which channel the conventional sign illumination into slit light sources registered to the apices opposite from the message display side of the sign. Thus, there is provided a three-message rotating message display sign array, which is especially adapted for light box mounting.
