Abstract:

An improved system for backlighting a visual effect of interest is presented. The system includes a lenticular luminescent lens, an electroluminescent (EL) light source and a power source coupled to the EL light source. The lenticular luminescent lens includes a luminescent substance disposed thereon/therein for providing the visual effect of interest when exposed to stimulating light. The EL light source is affixed to a surface of the lenticular luminescent lens. When the power source applies power to the EL light source, the EL light source activates an area of illumination backlighting the visual effect of interest.
