Abstract
A light film apparatus having an illuminated graphics panel with at least two segments that can be individually powered. A controller manages a power which is delivered from a power supply to each of the segments, so that each of the segments is either powered on, powered off or powered to an intermediate level. With the independent control of power to the different segments, it is possible to create a three-dimensional appearance of a moving image from a generally two-dimensional panel arrangement. A housing can be mounted so that the graphics panel abuts or is closely mounted to a mounting surface.
Claims13
A backlit graphic display device for illuminating a graphic panel, the backlit graphic display device comprising:
- a housing assembly, the housing assembly comprising a housing top, a housing bottom, a housing back, a housing front, and peripheral housing edging, the homing back comprising an assembly-receiving cavity, the housing edging defining a panel-receiving section in anterior adjacency to the assembly-receiving cavity;
- a light source assembly, the light source assembly comprising, in electrical communication:
- a power source, a light source, and a switch, portions of the light source assembly being receivable in the assembly-receiving cavity;
- a light guide assembly, the light guide being positionable in anterior adjacency to the power source in edge adjacency to the light source for guiding light from the light source in an anterior direction orthogonal to a light guide plate of the light guide;
- and device-to-window fastening means for fastening the graphic display device to a window, the device-to-window fastening means being cooperably associated with the peripheral housing edging for supporting the housing assembly such that the light from the light source is guided in the anterior direction, the anterior direction being orthogonal to a window plane of the window, wherein the laterally opposed retainer structures comprise hook and loop type fastening means for fastening the graphic display device to the window, the laterally opposed retainer structures being integrally formed with the housing back for receiving the hook and loop fastening means within a matable fastening means gap, the matable fastening means gap being structurally situated intermediate anterior surfacing of the laterally opposed retainer structures and a forward most anterior plane of the housing front, the laterally opposed retainer structures and the book and loop fastening means thus for mounting the anterior plane flush against a window plane of the window.

A backlit graphic display device for illuminating a graphic panel, the backlit graphic display device comprising:
- a housing assembly, the housing assembly comprising a housing back, a housing front, and peripheral housing edging, the housing back comprising an assembly-receiving cavity, the housing edging defining a panel-receiving section in anterior adjacency to the assembly-receiving cavity;
- a light source assembly, the light source assembly comprising, in electrical communication:
- a power source, a light source, and a switch, the light source assembly being receivable in the assembly-receiving cavity;
- a light guide assembly, the light guide being positionable in anterior adjacency to the power source in edge adjacency to the light source for guiding light from the light source in an anterior direction orthogonal to the plane of the light guide;
- and device-to-surface fastening means for fastening the graphic display device to a mounting, the device-to-surface fastening means being cooperably associated with the peripheral housing edging for supporting the housing assembly such that the light from the light source is guided in a direction orthogonal to the plane of the mounting surface, wherein the device-to-surface fastening means comprise laterally opposed retainer structures and hook and loop fastening means for fastening the graphic display device to the mounting surface, the laterally opposed retainer structures berg integrally formed with the housing back for receiving the hook and loop fastening means within a matable fastening means gap, the rentable fastening means gap being structurally situated intermediate anterior surfacing of the laterally opposed retainer structures and a forward most anterior plane of the housing front, the laterally opposed retainer structures and the hook and loop fastening means thus for mounting the anterior plane flush against a surface plane of the mounting surface.
