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.

Claims

1. A system for backlighting a visual effect of interest, comprising:

a lenticular luminescent lens having a luminescent substance disposed thereon and/or therein for providing said visual effect of interest when exposed to stimulating light;

an electroluminescent (EL) light source affixed to a surface of said lenticular luminescent lens for providing an area of illumination about said visual effect of interest; and

a power source coupled to said EL light source;

wherein when said power source applies power to said EL light source, said EL light source activates said area of illumination backlighting said visual effect of interest.

2. The system of claim 1, wherein said lenticular luminescent lens includes a transparent synthetic resin material having said luminescent substance mixed therein/applied thereto.

3. The system of claim 2, wherein the transparent systetic resin material is selected from the group consisting of polycarbonate, polyvinyl chloride, polyester and mixtures thereof.

4. The system of claim 2, wherein the luminescent substance is benzoyltrifluroacetone.

5. The system of claim 1, wherein said EL light source includes:

a layer of core stock;

a rear capacitive electrode layer formed on said core stock layer;

a front capacitive electrode power distribution bus disposed on said core stock layer and electrically coupled to said rear capacitive electrode layer;

a capacitive dielectric insulation layer disposed on said core stock and encapsulating said rear capacitive electrode layer;

an EL phosphor layer disposed on said capacitive dielectric insulation layer; and

a light transmissive electrically conductive layer coupled to said front capacitive electrode power distribution bus;

wherein said EL phosphor layer and said capacitive dielectric insulation layer provide electrical isolation between said rear capacitive electrode layer and said light transmissive electrically conductive layer;

wherein when electrical power is applied, current flows between said rear capacitive electrode layer and said light transmissive electrically conductive layer energizing said EL phosphor layer, illuminating said EL light source and backlighting said visual effect of interest.

6. The system of claim 1, further comprising one of a switch and timing circuitry coupled to said power source for selectively illuminating said EL light source and said visual effect of interest.

7. The system of claim 1, further including a top layer over the lenticular luminescent lens, thereby providing protection from the environment.

8. The system of claim 1, wherein the EL light source further includes a light transmissive polyester film environmental incapsulation.

9. The system of claim 1, wherein the EL light source comprises an ITO paste or powder applied directly to a surface of the lenticular luminescent lens.
