A system and method for presenting a visual message by illumination. The system includes an LED light source and a transparent sheet. The transparent sheet is a transmission medium that includes a modified surface that refracts light in designated areas. The LED source illuminates the transparent sheet so that the LED illumination of the sheet achieves a visual effect of a neon filled glass tube lighting. The illumination system, however, is neon-free. The modified surface includes a disruption pattern or a printed ink layer, or the sheet includes two modified surfaces, one modified with a disruption pattern and another one modified with a printed ink layer. The LED light source includes multiple LED emitters on a circuit board. The LED light source projects light through the sheet in a direction that is parallel to a surface plane of the sheet.
A system for presenting a visual message by illumination, comprising an LED light source and a transparent sheet, wherein the transparent sheet is a transmission medium that includes two modified surfaces, so that at least one modified surface refracts light in designated areas, wherein the LED source illuminates the transparent sheet, and wherein the two modified surfaces include one modified with a disruption pattern and another one modified with a printed ink layer.
